At this time I will give tips on cell phone repair tips, especially in the release or revocation of a given IC glue, because it is given the IC removal techniques glue is more difficult and more risky than the repeal of IC that are not given the glue.
Location of the position of IC on the PCB there are two, namely mobile phone IC in glue (resin) and ic laid without glue. for the removal of IC that are not glued together we have learned and this time we will learn how to lifting the glued IC. A lot of mistakes made when moving or lifting the IC is in the rapture glued and glued IC which has a substantial risk that could damage broken lines or damage to the phone PCB, risks taken in doing this component is big enough, just imagine if you have no charging damage on your mobile phone, having analyzed the damage caused by IC UEM (Universal Energy Management) and the chip was glued or protected by a resin, the removal of the one on the chip can cause further damage that could occur total dead cell phone. Surely you do not want your phone to be victims, Well this is the risk that must be taken by a technician, because it confirms to the customer is required before doing repair mobile phone.
IC is glued not to hard to be demolished or removed, but to preserve it for IC chip holder can be water resistant, impact resistant hard and not easily dislodged or tenuous that may cause damage. For mobile users actually an additional advantage provided by a product but still has a weakness that is if there is damage to the chip will be replaced, have a risk of more fatal. Substances used for adhesive glue it is like silicone or solid resin which is heated instead of melting it becomes 'brittle' and strong glue to be appointed. Generally, IC is given if we remove this adhesive from the PCB, the chip will be damaged, due to excessive heating to release the glue.

Another reason the process of appointment of glued UEM:

1 - Entrance of water that can damage the UEM

2 - Burned or shorting due to the high voltage of charge process

30-30 seconds autoshut Off usually after repair imei

4 - Insert sim card (insert sim card), although the sim card has been installed and others

Replacing Glued UEM IC or chip in the glue is rather difficult and requires full concentration. One cause of difficulty in removal of the glued IC is the use of nonstandard equipment in repair action. Please note the appointment of a standard instrument for investments needed funds BGA chips around $ 15.000 to 75.000, and certainly not the answer to a cheap and good. When we recall the saying goes there is no cane so the technician was trying to resolve this matter in another way that is still using steam solder for appointment.
Tools - tools that are prepared:

1. solder steam
2. siongka paste or flux
3. knife cutter (normally used scalpels that have eyes and the eyes of a flat taper)
4. tweezers
5. clip board (clipboard)

methods:
1. Use a hot soldering temperature steam with 350-400 ˚ C in air pressure from 2.5 to 3 or depending on the blower that you use.

2. Place the PCB for mobile phones on the clipboard during the work process does not shift or rock.

3. Use a good flux and place on top area and the ball - tin ball IC. flux function is to reduce damage to the PCB.

Use a knife with a pointed tip on the side of the function Ic for prying and lifting ic of the PCB. The appointment requires full concentration so as not to damage the many paths and the possibility to fly or missing other supporting components.
Warming temperatures are to remove the remaining glue or resin requires patience and it takes about 2-5 minutes, so just lift the chip confiscating waktu.jangan before certain liquid tin has been uneven, usually can be seen through the release of some tin of chips due to heat stress given.
Once lifted, the IC can be seen the remnants of glue which is located on the pcb, during the process of appointment of a better rest - the residual glue stick to the IC, so no need to clean up the remaining glue and just replace it with a new Ic.
Clean the rest - the remaining glue with a knife that has a flat tip eye. Work process is accompanied by the use of solder steam with low air pressure, using the fluxes and done gradually to avoid a break point on the PCB. The direction of the blade direction and not try random - messy.
After missing the remaining glue on the PCB PCB wait until cool and then clean the PCB by using liquid IPA (Iso propanol Alcohol). For PCB cleaner and easy to put the chip back.

In this post I wanted to share some tips on improving the damage phone just by using a secret code and the settlement was very easy to do in Mobile SmartPhone or adopting Operating System such as Symbian, Linux, Windows Mobile and Palm.
Many mobile phone users confused and panic if they find problems on his cell phone and they come to the phone service center to immediately repair the damage. In his mind there may be feelings of fear that if such damage could have a wider impact, so it must be immediately brought to the service center.

Actually there are some easy things that should be done in case of problems on your cell phone, which may very easily but did not have time or thought in your mind other possibilities do not know. It is easy it is to do a format and reset factory settings if your phone is having problems or more known as hard reset the phone. Perhaps part of mobile phone users do not know how to do it or feel scared and horrified to do that format. In fact by doing a factory settings reset so many minor problems on the phone that you think weight can be resolved by doing this.

After the reset process, then the phone will return the standard. Some mobile phones that adopt SmartPhone or operating systems such as Symbian, Linux, Windows Mobile and Palm are the initial setup feature, also provided a procedure to do a hard reset. It aims to return all phone data system on the condition that actually default standards vendor. So that all files, contacts, applications and all that is loaded after the phone purchase will be erased completely, so we'd better backup it first before doing the master reset.
Master reset is also useful to "refresh" the performance of mobile phones that feel increasingly slow and clean the phone system of junk files that interfere so often result in the phone hangs and error.

So all Symbian-based phones that most of the damage could be in because Software.Sebelum use software tool to repair (repair box) should try to do repairs themselves by way of a master reset on the phone. Master reset method on each brand and type of course different phone, for more details see some trick or method of a Master reset on a variety of mobile smartphone type the following:

Here is an experience - our experience in repairing damage to the phone by using a secret code in various types of mobile phones:
1. Overcome Hang that can make your phone's performance is slow or not working at all
2. Overcome the phone frequently or auto restart on of
3. Overcome the phone often turns itself off within a few minutes or hours
4. No Overcome ringing caused you activate the switch off the menu but do not know how to turn it
5. Overcome Compose SMS can not appear alphabet / letters, but which appear only numerical or numbers only
6. Can not write SMS Overcome due to missing folder
7. One Overcome Icon menu on the phone can not be activated or enabled
8. LOCK PHONE Overcome emergence messages on mobile phones
9. Overcome Display menu chaos reigned
10. Overcome the virus into the cell phone
11. Overcome the emergence of the message "application closed" on the phone
12. Overcome the emergence of the message "System Error" on your phone
13. Overcome the emergence of the message "Phone start-UP CONTACT RETAILER" on mobile phones
14. Overcome nokia blink 4 times on your Nokia series symbiyan
15. Overcome error camera when taking pictures or NOT READY message appears camera and can not be used
16. Overcome the emergence of the message "MEMORY FULL" when the contents of memory in a state still many empty
17. etc

Some important things to consider before making these improvements:

1. The phone will return to the initial settings such as the beginning of factory settings, so that important data such as Phonebook, ringtones, pictures and applications will be lost. Use the built-in software such as PC suite to back up data or if your phone uses an external memory move the data into the memory.

2. Memorize the location of the language setting, to prevent the display language change that can make you confused, especially on the phone - the phone that you lack an understanding of the menu.

3. For the series comunicator Officenya you can delete the file so it must be installed again.

Ways to Reset on various mobile phones based on the sequence of damage that is often encountered:

PDA (Windows Mobile)

"PDA" (Personal Digital Assistant) was first introduced to replace conventional organizer (organizer). Where once people use the agenda to record all activity schedules, phone numbers, or to help in reminding the things that mattered to him. But with the increasing rapid development of computer technology. With the found and the introduction of an electronic organizer or often referred to as PDA (Personal Digital Assistant), then people are now starting to replace conventional organizer with PDA to help him in his daily activities. But in its development, the manufacturer of the PDA is to improve its PDA capabilities. In terms of software (operating system and application) and in terms of hardware (processor speed, color screen, large memory) is also in terms of physical form an increasingly small. Now the PDA also has added a variety of attractive amenities such as the ability to create a network without wires (wireless), ability to function as a cellular phone, as well as digital cameras.

To check, you can see from the durability (life time) and standby time and talk time, we can examine and test the phone by using the power supply with the following steps :

* When your phone is turned off (off) this is the mobile phone has taken the current in the battery, this is proven by needle amperes at power supply shows the number 100 milli amperes. Things like this that causes the cell phone battery wasteful, because the cell phone constantly taking the current from the battery even though the phone was dead.

* Now remove the IC PA first.

* Do re-test such as the above, see the needle ampere if silent, then certainly the PA IC is faulty.

* Replace the PA with a new IC, do re-test such as the above, see the needle ampere, ampere needle should remain silent.

* Battery you are not wasteful anymore.

The problems the keypad on the phone there is some sort, though very rare event of damage on the phone keypad. Here are some types of damage on the phone keypad along with the solution :
* If one keypad is pressed but does not work, for example number 3, we check and test voltage (volts) in key 3, the voltage (volts) that comes out is 0 V, it means there is no voltage (volts) comes out. Such damage can be caused by poor connectivity on track, we try to clean first keypad brass plate on the PCB by using an ordinary pencil eraser we use. If still not successful then we do the jumper by the way: For instance was the number 3 is not working then jumperlah number 3 was the number 2 (horizontal) and item 6 (vertical), the jumpers 'outer circle' brass plate between the number 3 with number 2 (horizontally), then the jumpers 'sphere of' brass plate between the number 3 to number 6 (vertically).

* All the keypad does not work alias 'hangs', then check and test in advance whether the IC Power is still good, just warm up if IC Power is still good, or replace it with a new IC Power IC Power if it turns out it is damaged. After that do the program (flash).

* One of the keypad when pressed then the exit is not the same, for example, we press the number 5 but who came out number 1. We check and test voltage (volts) at the 5, then the voltage (volts), the exit is 2.0 V. Such damage can be caused by poor connectivity, we do like the way the jumpers above.

* One button is pressed it causes the phone to die, if we check or test the voltage (volts) emitted is 2.8 V.

* The solution we do the inspection and testing before the ICs ¬ Power, Heat Power IC if not damaged or replace it with a new Power IC if it is broken, then do the program (flash) your phone software.

Blogger friend, Charge it could not function so there is some possibility of damage: The damage occurred on the appliance rechargeable (charger) battery itself, try your charger on the mobile device and another similar to find broken or not. Battery is damaged on your mobile phone can also be so battery can no longer be refilled. Check if the battery recharge connector on your phone is still good. Then we just do the inspection and testing of the phone itself.

* If your screen appears the message "Not Charging" or cell phone refill process (charging), but the indicator Rechargeable battery runs without charge or refill process (charging) but refill indicator did not say anything then surely its IC Charge damaged. Replace with new IC Charge

* Mobile phones are finished rechargeable (battery full), but the refill indicator keeps going on, then his power IC damaged. Replace it with a new Power IC.

* The phone is not in a state rechargeable (charge), but the refill indicator road continues, then the software (SW) are damaged. Do the program (flash) on the phone with the same version.

* The phone will be done every refill process (charge) is always dead, then the Charge or IC Power IC damaged. Perform inspection and further testing on the phone to determine whether IC or IC Power Charge and then replace the damaged IC or IC Power Charge damaged.

* After charging (charge) phone with a charger, no leaks before the electrical power-on button is pressed, when you press the power button-on, the phone does not work. The cause of the problem is electrical leakage in power supply capacity. The goal remains the Power IC, IC UI, PA IC that is connected to the voltage batteryt VBATT, the units are often damaged and can create problems is the Power IC, IC UI. Because Power is a BGA IC, the IC is integrated, then the method that is usually done is to remove IC UI, then recharge (charge) returned the phone, note whether there is electricity kobocoran. If not, then IC UI damaged, if any, means the power IC damaged. The problem is completed, after the replacement IC above.

* We recharge (charge) the phone, then press the ON button, but the phone did not fire, no electric current that goes into the phone. If so then take the measurement on the R224, if both ends do not have the VBAT voltage is 3.2 V, the mean IC Power is damaged or there is a poor soldering on the IC power. Power IC Replace damaged or re-do the soldering on the IC Power.

* Try to re-flash your phone manner.

On the phone that dumb, if we use mobile phones, then the other person can not hear our voice, we can perform inspection and testing of components using multitester MIC with the following steps :
* Use the manual on the scale multitester xl, the positive pole cable ties and cable from the negative pole on the legs multitester MIC component, if the needle moves so multitester MIC components in good condition. But if the needle on multitester not move then we need to replace components of the MIC, for MIC of damaged components.

* Next we test runs of MIC components. To test MIC kaponen point, we also use the manual on the scale multitester x1, connect the cable interface multitester with MICs in the positive and negative poles, if multitester needle move, then the good path, but if multitester needle does not move, then the line disconnected MIC. We can do a jumper to handle system.

* If a good path, try to heat the IC Audio using a blower.

* If the phone is still silent, replace with a new audio IC.

* After we are done in hardware but the phone was still silent, then there is damage to the program (software) phone.

In this article I want to share some solutions to improve mobile phone that has a problem with the Contact Service.
Mistakes like this on mobile phones means that the software can run normally, and therefore the ability of IC Power (CCONT) can work. Function selfttest running when power is turned on and the software is run from flash. If there is selfttest that fails, the text "Contact Service" will be displayed on the LCD. Errors in general:
* MCU ROM checksum fails, try the program (flash) your mobile phone. If your phone is still not right after the program (flash), soldering machine and try to update your phone software once more

* Interface CCONT failed, most likely due to CCONT damaged or defective soldering or less good. Mistakes are almost certainly caused by MAD or PCB (track) is damaged.

* Parallel / serial COBBA failed, possibly due to the IC COBBA damaged or defective soldering or less good. Try to replace COBBA. If it still fails, the error caused by MAD or PCB (track) is damaged.

* Check software

Good luck, and good luck ...

In this tutorial I want to share to solve the problem of the phone signal is not stable, sometimes strong, sometimes weak.
Repair procedure:

* Check whether the phone can be used to search the network by way of manual. If the phone can not find the network manually, then the RF IC (HAGAR) is damaged, replace the RF IC (HAGAR.

* Also check that the path to the IC PA uninterrupted.

* If the reverse cell phone network can find the manual way, then the PA IC damaged, replace the IC PA.

* Once the hardware of the phone has been tested and repaired but the problem persists, we need to reprogram / flash again phone software according to the type and version of the phone or with a newer version of the previous phone software version.

* Turn on your phone, then your phone will function normally again.

Hopefully help ....

Unstable signal problems can sometimes be frustrating when we are in need phones to make calls function comparatively important. Signal problem is actually caused by 2 things namely, the quality of the signal from the BTS operator weak and condition of the phone itself does have a problem in it. If the signal beam BTS does not have any problems at all then surely, a problem that occurs due to the phone.The phone is in trouble with the signal also has 2 possibilities. Problem is guilty of a software or hardware. The first step that must be done is to repair the software by tuning signal. If after tuning the signal still has particularly a problem, then the last step is to make the turn on the switch components of the antenna, RF IC, PA, Audio and more associated with weak cell phone signals.

Switch antenna is weak, it does not mean to do the turn. If it has very limited funds, then we can do the jumper switch the antenna without having to replace the IC PA.

The equipment must be prepared in advance are:

1. Tin solder 0.3 mm following
2. Fluid Flux
3. Jumper cable 0.3 mm

The steps that must be done:

1. Disconnect the phone casing to stay PCB / Board Phone

2. Prepare a jumper cable to be connected at appropriate points in the image, precisely in the IC PA

3. In the picture above, we do the jumpers on the phone 33XX

4. After making jumpers, combine parts of the phone back to normal.

5. Mobile phones can now be used to capture a better signal.

Trick antenna switch jumper this will affect the ability of dual-band mobile phone into one band only, ie 900 MHz. This trick is very useful to get around the limitations of funds. If you do not want to lose the ability to dual-band mobile phone into one band only, then the alternative is to make the turn with a new IC PA.

Good luck...

Make sure also that the phone is not stolen cell phone by looking at the completeness of the used phones, including: the dos and the manual that came with the phone, also complementary accessories that sometimes also included when purchasing a new phone, for example: handfree.

3. Non-warranty or Black Market (BM)
Do not buy a phone that black market (BM), because the risk is often the case jamper on its PCB and if entered the program files (flash) on the original software is often the case "Contact Service" and other damages, and sometimes it is not biased restored so that the phone could not be used at all (Matot)

4. Physical Condition
Check out the conditions and the phone is it still in good condition and most importantly is not disabled. You should also open the phone casing is to ascertain whether the mobile phone has been dropped or had improved (the service). Note the condition of the LCD is still in good condition or has been blurred, also check keoriginalannya. After you check the condition of the phone, then the next turn on the phone, try all the buttons on the keypad if there is a stuck or even not working. Try pressing any number key on the keypad as much as possible and make sure the phone does not hang. Then make sure the functions on the menu all works fine, for example: ringtone, vibration, etc.

5. Signal
Make sure the phone signal is still good. Just compare similar phones with the same network card. If the phone when you try a sudden die alone so be careful, the phone is problematic, this could be due to battery and its weak IC Power.

6. IMEI number
Check carefully whether the same all the IMEI number of the phone (usually printed on the back of the phone / behind the battery), the IMEI number on the program your phone (mobile machinery) and the IMEI number listed in phone boxes. This is done is to make you easier to sell this phone back later because the IMEI number has been fit all.

7. Battery
Battery is included on some phones the former certainly has the power of life (life time) is shorter, such as guard time (stand-by) and talk time (talk-time) will be shorter. Another case when the phone battery is new or you buy a new battery. To test the battery then do a call using a phone to call someone or call toll free in the long term.

8. Charger
Notice his charger. Usually that is not original charger its long process, otherwise the original fast charger of his process. Physical charger is heavier than the original that is not original. Longer than the original cable that is not original.

9. Spare parts
We suggest you choose the phone that has a lot of network service, it easier for you in repairing the damage that may occur when you use these phones, as well as the availability of spare parts / spare parts or accessories that complete mobile phone.
