Problem with Sigmatel V88
 

I have strange version of Sigmatel V88, first of all when i was looking for pinouts i have noticed that their differs from others V88:

Sigmatel v88 pinout
keypad up
con type 2x6
pin 5 rx
pin 6 gnd
pin 8 tx
pin 12 +vbat

This is what i found for others, but for mine it is different:

keypad up:
1 - - - - 6
7 - - - - 12

3 - tx (tx and rx may be swaped)
10 - rx
9 - GND
6 - B+

Connecting by this i can flash my phone, everything works fine. But i think that if connection is different maybe the flash file is different too? I have tried lots of flash versions but no luck. The phone turns on, plays welcome music, the keyboard works, but the screen is totally white. Tried Nokia 6300 flash , but the same - white screen. Maybe it can match flash from other china phone?
Here is the details of phone and its flash:
Flash: v04SZMI25_06B_PCB01_GPRS_MT6225_S00.MAUI_06B_W07_2 4.BIN
CPU: MT6225
Nor Flash: SAMSUNG K5L2931CAM
LCD type: FPA-S5T28T-02
Dual SIM

Thanks in advance

any solution for my problem?

Today i have flashed v04CREATONE25_K817_ESPIGIVRT_PCB01_GPRS_MT6225_S00 .CREATONE_K817_ESPIGIVRT.BIN flash file from Sigmatel S66 to my V88, and you know what, the display worked!!! but the keyboard was working different, you press 1 - presses 4 and so on, and the sim was not working too. Maybe this would help to know wich flash would be perfect for me ... :rolleyes:

You might be SOL if you don't have an original backup (which I'm assuming you don't, and that's why you're trying different images). There's a bazillion kinds of MT6225 phones, and not uncommonly totally different hardware within the same model. Your best bet is to try and find someone with the same kind of phone (and hardware) that you have.

Good luck

Yes i understand that. So maybe there would be kind V88 owners, that could check their phones LCD type and pcb and share the backup? :rolleyes:

Now i need to wait and try all the similar firmwares ;)

Thanks in advance for help
