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 ...
