RX TX CHINA MOBILES

Method 1: HOW TO FIND RX TX It is tasted and also you can test it. 1 step is, we need to find GND from phone. 2 step is, we should power on phone (operation with dead phone: phone must be 100% dead by software)and take multimater put it to voltage. 3 multimeter (-) line put it GND and with (+) line check each connectors , and usually Tx= 1.8v or 2.8v and Rx=1.7v or 2.7v (it will be change by processor but strongly 1.7v or 2.8v not 3v or 4v) This way is too easy and you will save a more time. Method 2: How To Find Rx,Tx "The Multimeter Method" 1. Plug your new connector into your phone, with solder pads/pins exposed 2. Put Multimeter into fault-check. (or if unavailable, then it’s highest resistance range) 3. Keep negative Multimeter probe on negative battery connector in phone. 4. Touch each pin of the connector in sequence with the other probe until you hear a beep ( or see 0.000 resistance ) 5. Note this connector pin as GNDPin 6. Now install battery and switch on Phone 7. Put Multimeter into DC voltage measurement 8. Keep negative Multimeter probe on GNDPin 9. Touch other pins of the connector in sequence and note pins that have voltage between 2.6 and 2.9 volts.(be careful not to short pins ) 10. You should end up with a list of 2 or 3 pins. RX and TX will be among these. 11. Try all combinations of RX and TX with these pins you found. I’ve found several hundred pinouts with the method above. It works 99% of the time, and takes about 2 minutes once you’re in practice. So you now have your RX, TX, GND wires on your interface end, and your pinout or set of pinouts to try for the phone.

REPAIRE DEAD CHINA MOBILE PHONE WITH DC POWER SUPPLY

) How do you can repair your china(chip) dead phone with a power supply(DC Supply).

I share here my some idea .

(1) 1st check dead board via volt miter have short or not? if not shot you can go ahead for next step.

(2) take power supply war and connect phone v+ with power supply v+ and v- with phone v-.
(3) press phone power button and see phone volt reading........its show what ?

(4) if power supply reading nothing i mein reading0.00 change cristal clock ....then check volt . all is ok set must go on ,cause main ic not found power 4 this missing.

(5) if power supply do reading 4-6 its 1st try to format or flash ....if set not open ..then re-hit power ic with hot air and solder pest.all is ok set must go on.
(6) if power supply reading 35-45 reading ....its must be flash ic(Ram) problem ....now re solder flash ic with hot air .

HOW REPAIR DEAD MOBILE SET

How You Repair A Dead 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
Bt ic
Last try is cpu.

HOW REPAIR DEAD MOBILE PHONE

How to Repair a Dead Mobile Phone

---

If the mobile phone does not switch on, it is called a dead mobile.
It can be due to many reasons
1. Water damage
2. Fall down
3. Not used for a long time ( Mostly battery is down)


(1) Check the Battery. It should show 3.7 volts or as written on the battery.

(2) Check the Battery Connector
Check two things (a) Voltage coming or not (b) shorting
Note : If there is shorting then clean the circuit in ultrasonic cleaner (Remove display, camera, etc before putting it in ultrasonic cleaner )
Clean the circuit with a soft brush and make it dry with a hair dryer or ****er.
If the shorting does'nt go it may be due to shorting in an ic,capaicitor or circuit. if shorting is in ic u can check it by attaching a battery then press the on-off switch keep the battery for 10-15 seconds. after that remove the battery and check which ic bacomes hot. Reball or replace that ic. If shorting is in circuit it must be removed by ultrasonic cleaner
Note - The circuit is made of three layers. if there is shorting in the middle layer it cannot be removed
(3) Check the On/Off switch & voltage at on-off switch
Note - Connect a charger. If charging is shown on display then the problem is with the on/off switch or software problem

(4) Try flashing the mobile.

(5) If flashing cannot be done then there is hardware fault we first dry solder the Flash IC & RAM IC and check in the Software. if flashing cannot be done then we dry solder/reball/replace flash ic & RAM ic.After that dry solder/reball/replace Power IC, Network IC, Crystal, CPU

WHITE DISPALY

whose got white screen afte

This is for anyone whose got white screen after changing Display (display ok).
1st Step : Read Flash file from spiderman.
2nd Step : Flash with another flash file with different CPU (if the phone has MTK6225, flash it with MTK6223 or other CPU flash file)
3rd Step : Now flash it back to the original flash file (flash file from the 1st step).
I hope this works for everyone. I got it work with G' Five U808.

TESTING OF MOBILE PHONE

Mobile Phone Repairing Testing Methods

Faults in each part, component or section of a mobile cell phone can be repaired fast by using following 2 methods at the time of repairing mobile cell phone. These methods can also be used to find out faulty or damaged parts or components inside a mobile cell phone.

1. Cold Testing Method: When we check the value of resistance using a multimeter at the time of repairing a fault in any mobile phone, it is called cold testing. There is no need to give any power supply to the faulty mobile phone from any equipment such as DC Power Supply or battery during cold testing. Diode Range and Beep Sound from the multimeter is used to find fault in a mobile cell phone using the cold testing method of mobile phone repairing. In this testing method, the RED Probe of the multimeter is connected to the ground of the mobile phone PCB and the BLACK Probe is touched at the testing points of the mobile phone. During the fault finding and repairing process of each part, component or section, following correct values will be received:
   1. Ear Phone Connector Tip (+ , -): .500 to .700
   2. Loud Speaker / Ringer Connector Tip (+,-): .300 to .600
   3. Battery Connector Tip (+): .400 to .500
