Touch Screen repair
Touch Screen IC 4182A and MT6301 same. See X- X+ Y+ Y- reference my picture jumper.
Touch Screen use of 4-wire resistance screen, four lines are: X1, X2, Y1, Y2
X1, X2 in the horizontal direction for a change in the resistance, Y1, Y2 for the longitudinal resistivity.
How do you know which line is a two x1 x2 y1 y2? Touch panel along the four lines above are facing their own look at the screen from top to bottom in the line is about on both sides of the x1 x2 is y1 y2. Established phone touch screens measuring four points of the voltage. Two 2.7V and two 0v . two voltage are measured after boot. 2.7 v is y. X is not the voltage.
After corresponding with xy can generally be connected. If the touch panel screen and click position opposite or reverse. Swap contrast x-y reversed.

How To Make China Phone Flash Cable
Many of new member face the problem, how they make a usb to com cable for flash his china phone. with this usb to com cable any one can use free soft for do software operation on his phone.
with a usb to com cable (as like ringtone cable) you can make your own cable for flashing, format, ect for china phone.
i explain here with a Motorola c261 usb ringtone cable, its always do better work for me.
first collect a cable of Motorola c261 usb ringtone cable (available in market) like this-
in cable middle have intact a box by plastic. in it have a mini pcb. need to open this
mini box for see and work on it. see picture-
after open it, now we see a mini pcb, its one side have 5 cable, which is connect to pc usb, no need to touch it. its ok.
we work on pcb opposite cable connection, here have 3 cable. 1 tx, 1rx, 1gnd. see pic-
here have 3 cable, now make a connection for V+ or B+. when we flashing our phone we need power supply for flash phone. so connect a cable with clip in this point, just use a diod from pc usb V+, see picture-
for cable driver, use it motorola usb to com cable drive or you can use PL2303 USB driver.
connect cable tx rx gnd B+ to phone tx rx gnd B+ and work your phone. now we found our won cable for flashing china phone.
for expert user : now you can collect a RJ45 connector. than join tx rx gnd in in RJ45 Socket. now you use any rj45 cable with it. and place it on any box, as like in any reject device, open box and leave it old pcb than place this pcb in it. and V+/B+ cable and clip stay in out or side for give power supply to phone. now you found a complete china box/device and use it.

All Common Problem Solution For China Phone
How You Repair A Dead China Phone:
First we need to know why a phone is dead-
1. For Software
2. For Hardware
1. For Software-
Flash is its final solution, but mtk cpu 90% phone done by format. if its MTK,SPD,AD, SI4904 cpu first try to format than try to full flash your phone with a good and perfect flash file. and other cpu haven't format option, so direct flash them. when you flash careful about original flash file version.
A. what you do before format or flash-
Always remember, before format or flash of your any china phone must first backup your current flash file if phone is dead, also do it. because it will help to find its original flash file version and many other.
B. What you need for flash or format a china phone-
(1) Connecting device (also your can do it with usb to serial cable but a device/box can give you full/final solution)
(2) Phone TX and RX.
(3) Need to know phone cpu type/model, flash chip type/model, Flash file version.
(4) For Flash need a good flash file which same to your phone original flash file version.
C. What problem you face for wrong flash file
(1) phone still dead
(2) white screen
(3) keypad not work
(4) phone hang after power on
(5) keep restarting
(6) no network
(7) etc.
Tool For MTK Flash info
2. For Hardware-
when a dead phone not possible to repair only with software you need to repair phone hardware.
Which hardware you need to check for dead phone-
(1) when you try to flash if phone not boot check power source/battery voltage/V+ pin in phone connector. just do confirm phone found enough voltage for software operation.
(2) if phone power source is ok but still not boot, do confirm your tx and rx is 100% working/tested.
(3) if tx rx is ok, than check your phone connector, its tx rx pin is confirm connect with cable and internal connector pin is joint on pcb perfectly.
(4) if pin is ok, maximum china phone tx rx going to cpu after crossing a resistor or capacitor so check them.
(5) if resistor is ok now you need to check boot diod, all phone have no boot diod so last try is check cpu tx rx pin.
(6) if boot is ok but phone not receive flash file, maximum time this problem coming from flash ic or ram (maximum china phone flash memory and ram have in one chip). so you need to try first re-hot it if still not solve change it.
but its true flash chip/ram always show error not only for them, sometimes cpu to flash chip/ram connection lost for bad cpu pin or bad cpu soldering on pcb. so check both of them.
(7) phone flash ok but not power on (although file is 100% correct) , for it you need to check
Flash chip/ram (95% include in 1 chip)
Clock crystal and battery
26mhz (near rf ic)
Rf ic,
Power ic and v+/b+ way

How to repair keypad problem in china phone-
First we need to know china phone keypad connected with PCB how way-
(A) Direct on PCB
(B) Flex System (flex cable direct soldering pcb to keypad panel)
(C) Flex and socket system include (flex one side soldering with key panel other side connect to pcb with socket)
(D) only Socket System (here have 2 socket, 1 with key panel others with pcb)
Keypad problem have various type-
1. All key not work.
2. some key work and some other not work.
3. sometimes work and sometimes not work.
1. All key not work
china phone all key not work for this type of problem-
(A) though its touch screen phone, first try to disconnect touch panel line from phone pcb or display flex (4 line)
(B) though not solve and keypad direct on pcb first you try to good clean full pcb with cleaner.
(C) though not solve now you try to format/flash your phone because some time key problem come from software problem.
(D) though still not solve now you check must be CPU. 95% china phone keypad directly going in cpu. and other 5% first going to resistor or capacitor near the cpu or keypad than going to cpu. so now first check them than you can try to re-hot, re-soldering or changing cpu.
(E) though its flex or socket system, first check GND connection continuslay pcb to key panel. next check full flex or socket all line going continuously pcb to key panel or not. also sometimes flex or socket shorted with other line or gnd so check also them.
(F) Also you can check all key anyone is short 2 line.
(G) sometimes keypad line broken from cpu pin on pcb to key panel, so check them.
2. Some key work and some other not work-
Some key work and some other is not work for this type of problem-
(A) maximum time this problem we face for flex or socket system keypad. so check flex cable and socket all line any line is broken or not and though need change them. and check all key connection on key panel.
(B) though its direact on pcb, some of key line broken internaly. and maximum china phone have alternative test point near every key or with other key on keypad. so check them with multimeter and though need connect to not work key with near testpoint or other working key.
(C) common problem is keypad metal ball (which is short 2 line on key when we press) sometimes its damage for phone water damage or over key voltage, so clean them or change.
(D) also try to check line continuously from cpu to not working key.
3. sometimes work and sometimes not work-
this problem come from this defect-
(A) flex or socket system keypad any line is bad soldering or do lose contact. check them and
re-soldering or keep there line join with extra ware.
(B) for cpu bad soldering or cpu pin is broken. so re-hot or re-ball cpu.

Repair Display Problem Of China Phone-
China Mobile Display Type-
1. Flex system
2. Connector/socket system
Display Problem Come From-
1. Display Damage/Broken/ Broken Microchip area in display
2. Flex and parts damage
3. connector damage on both (pcb and display flex)
4. wrong software.
5. Display line broken from display connection to CPU.
6. CPU internal display section Damage.
China Mobile Display Type-
1. Flex system
2. Connector/socket system
Display Problem Come From-
1. Display Damage/Broken/ Broken Microchip area in display
2. Flex and parts damage
3. connector damage on both (pcb and display flex)
4. wrong software.
5. Display line broken from display connection to CPU.
6. CPU internal display section Damage.
1. Display Damage/Broken/Broken Microchip area in display
For this type of problem, have no way without display change (every one know it). so just
change display.
Display Microchip area on display panel-
2. Flex and parts damage
Sometimes we can see with our won eyes where is broken flex line or any parts.
but maximum time we can't see it normally. so we try to repair our display, when we confirm
phone show display problem only for display panel not for any type of pcb defect. can we
confirm it by replacing a good display on pcb. when we 100% confirm problem only on display
panale than we can try to repair it. otherwise first fix other problem.
For this type of problem can you repair flex cable with extra wire, but first need to
calculate flex cable all line with multimeter. some times line cross flex cable 1 side to
another side by in flex. so check them. and you try to change this type or parts, see picture-
here i mark some parts and only one type of display, other display parts find by your self.
though possible, change all parts from another display (which is broken but parts is ok)
3. connector damage on both (pcb and display flex)
Connector/socket system display create problem from there connector. so check simpaley there
all line with multimeter and fix them. though need join them with extra wire from direct pcb
to display. also you can change both socket.
4. wrong software
for wrong flash file or software problem we face white screen problem. so take any step before
do 100% Confirm its not for software problem.
we maximum time face this problem after flash or format. so after flash or format when a dead
phone is power on. we can 90% confirm its for wrong version flash file. so first see your
original flash file version than backup it and next flash phone with this same version
new/another ok file.
5. Display line broken from display connection to CPU.
98% china phone display line going direct cpu and other 2% have display ic. and sometimes
display line broken or break soldering from cpu to pcb middle point. just cpu bad soldering.
so can you try to re-hot cpu with your won risk.
also sometimes pcb internal line broken from cpu to display connection point. so check them
and fix them. (but do it after changing a good cpu though still display not ok)
6. CPU internal display section Damage-
Sometimes phone all section is working ok (without display) but have no display still after
change a good display (soft ok also) now you need to change must be cpu. because many time i see
phone all section work ok but have no display, after changing a good display phone is ok
100%. can anyone question, though its problem from cpu so how phone all section work ok. ans is
- phone all section work ok because only display area damage internally in cpu but all other
section have no problem.
Sometimes we can see with our won eyes where is broken flex line or any parts.
but maximum time we can't see it normally. so we try to repair our display, when we confirm

Connector/socket system display create problem from there connector. so check simpaley there
all line with multimeter and fix them. though need join them with extra wire from direct pcb
to display. also you can change both socket.
4. wrong software
for wrong flash file or software problem we face white screen problem. so take any step before
do 100% Confirm its not for software problem.
we maximum time face this problem after flash or format. so after flash or format when a dead
phone is power on. we can 90% confirm its for wrong version flash file. so first see your
original flash file version than backup it and next flash phone with this same version
new/another ok file.
5. Display line broken from display connection to CPU.
98% china phone display line going direct cpu and other 2% have display ic. and sometimes
display line broken or break soldering from cpu to pcb middle point. just cpu bad soldering.
so can you try to re-hot cpu with your won risk.
also sometimes pcb internal line broken from cpu to display connection point. so check them

VERY EASY WAY TO SIGN UNSIGNED APPS!! Even my grandma can do it
Now this is what i call a fast signing procedure of unsigned applications. It doesnt take more than 5 seconds and 4 clicks on your computer to sign a unsigned application!
First, install 2 sis application on your phone.
Then open the RootSign.exe on your computer
Choose the unsigned application that you want to sign.
And its done!
In order to install “Unsigned” releases, you need to go through a one-time procedure. You will need to run the in the release included “SecMan.exe”. This program allows you to install our future “Unsigned” releases, without signing them every time.
For this, you will need to have TRK (included in this package) installed, and connected to your pc via USB connection.
s60_3_0_app_trk_2_8_6.sisx for SymbianOS9 devices WITHOUT FP1 s60_3_1_app_trk_2_8_6.sisx for SymbianOS9 devices WITH FP1
To get this app properly running, make sure you have installed the newest Nokia PC Suite, and your phone connected via “PC Suite” mode. On the phone, run the TRK app, in applications folder. When it asks for bluetooth connection, don’t turn it on, and change connection settings to USB. After you have done that, click “Next” and follow the instructions on screen.
When the installation is done, look in the Applications folder on your phone, and find SecMan. Open it, and click on “Install Root Certificate”.
After this is done, you will be able to install our future “Unsigned” releases like normal “Signed” applications.
Please keep in mind, if you format / upgrade your phones firmware, you’ll need to do this step again and after that manually install those apps from Application Manager.
NOTE: To install previous unsigned releases, use RootSiGN v1.0 (Included in the package) first to sign these releases with our root certificate. This can be used to sign and install any unsigned .sis(x) file
Thx to X.Factor for the info and BiNPDA for creating this app!

How to Change iPhone 3G Battery
Each step has a bullet indicating the tool you'll be using. Don't worry about getting lost or confused; hundreds of people have successfully used the Fixit Guide series to repair their laptops.
Tools used in this guide
-Metal Spudger
-Phillips #00 Screwdriver
-Spudger
Parts relevant to this guide
-iPhone 3G Replacement Battery
Step 1 — Battery
Remove the two Phillips #00 screws from the dock-connector end of the iPhone.
Step 2
There is a fragile rubber gasket between the silver front bezel and black display assembly. Keep your tool as close to the silver front bezel as possible to prevent damaging the gasket.
We recommend a metal spudger for this task, but an X-acto knife should also work, just be careful not to slip.
Insert a metal spudger into the seam between the silver front bezel and the black display assembly on the edge closest to the home button. Gently pry the display assembly up from its bezel.
Step 3
If necessary, insert the metal spudger in the same manner on the side of the iPhone and continue to pry up gently. Stop using the metal spudger once the display assembly is up enough that you can lift it up with your fingers.
Step 4
The display assembly is still connected to the iPhone by several cables, so don't try to remove it entirely just yet.
Rotate the display assembly up until it is at an angle of approximately 45 degrees.
Step 5
Continue to hold the display assembly with one hand, and use your other hand and a spudger to disconnect the black ribbon cable labeled "1."
step 6
Rotate the display assembly up until it is roughly vertical. This will allow easier access for disconnecting the remaining cables.
Use a spudger to disconnect the black ribbon cable labeled "2."
Step 7
Use a spudger to flip up the white plastic tab holding the remaining ribbon cable in place. The white tab will rotate up 90 degrees, releasing the ribbon cable.
Slide the black ribbon cable out of its connector, and remove the display assembly from the iPhone.
Step 8
Insert your SIM eject tool or a paper clip into the hole next to the headphone jack.
Press down on the tool until the SIM card tray pops out.
Grasp the SIM card tray and slide it out of the iPhone.
Step 9
Use a spudger to disconnect the ribbon cable labeled "4."
Step 10
Use a spudger to disconnect the ribbon cable labeled "5."
Step 11
Use a spudger to disconnect the ribbon cable labeled "6."
Step 12
Carefully peel up the small sticker labeled "Do not remove."
Step 13
Remove the following 8 screws:
Five 2.3 mm Phillips #00 screws with partial threads securing the logic board to the rear panel.
Two 2.3 mm Phillips #00 screws with full threads securing the logic board and camera.
One 2.9 mm Phillips #00 screw from beneath the "Do not remove" sticker.
Step 14
Use a spudger to gently pry the camera up and out of its housing in the rear panel. The camera cannot be removed entirely yet because it's connected to the bottom of the logic board.
Step 15
Use a spudger to gently pry up the end of the logic board closest to the dock connector.
If the board won't lift up, double check to make sure all the screws securing the logic board have been removed.
Step 16
Slide the logic board towards the dock connector and out of the iPhone.
Step 17
Use a spudger to pry the battery up from the rear panel. The battery is attached with an adhesive strip around the perimeter of the battery. To prevent the battery from bending during the removal process, we recommend against using just the plastic
