Problem white screen on my devo 7e

Hello !
One month later, i've moded my devo 7e with a 4 in 1 module and deviation 5.0 with success but since many days, i've only a white screen

I've flash and flash again but nothing change. the screen display anything

I guess the SPI works because i've the welcome signal when i turn it on and i've recheck wiring with the screen but everything was not clear : i've clearly found only data/command, clock and CS pin but not mosi or miso ?
and it apear clock have no signal...

There is any way to debug this ???

EDIT : i've use this for my mod : www.deviationtx.com/forum/how-to/5955-7e...he-devo-version-4in1

and this for my research of the problem : pin mcu

thanks for your help and your job. In the small period that worked, i was realy happy to control all of my models !

Hi

No answer ! but this day i've see something (not on my screen sadly T.T) on the error.txt file. I've try to flash it again and format and finaly put fresh file dans it's trys to write something on it. before power on after flash, the file have a size of 1Kb and after power on, 4Kb ! it contains "empty" and a lot of char after. i join the file and i try to open it with an hex editor

Edit : it seem it write a lot of 0 ?!?
