Asus GL502VM Unlocking Menus
#1
Hiya
Firstly where is BIOS data physically stored?
I'd like to dump and flash using CH341A programmer and SOIC8 clip as I've previously done on other laptops but on this laptop the resultant dump using flashrom is too small, only 1Mb and not recognized in usual AMI BIOS tools or any other tools.
I dumped ROM using ftpw and the size was good, around 6Mb like Asus official, and the dump could be opened in AMIBCP.exe

So I guess I'm attaching SOIC8 clip to wrong chip?
Circled in red is the chip I clip
bios chip?

I'd like to open up the menus and see if ROM is stable with removal of ME via me_cleaner.

Current ROM can be found here GL502VMAS304.zip
The valid dump I created:  dump-from-fptw.rom
Bad dump: dump-from-ch341A.rom

I searched the forum and a very similar GL702VM (just bigger screen I think) seems to have menus opened up and a GL502VS (GPU is 1070 rather than 1060) has it's own thread with good work done.

Cheers,

Bios size is 8mb but your dump bios is 1m , so i guess you read error chip(EC??).
Its name should like w25q64fvssig or mx25l64xxx ,you can re-search correct bios chip again in motherboard.

Thanks. I had another look and found the right chip (W25Q64FVSIQ) and now the clip read/writing is working. 
I've upgraded my ME firmware then killed the ME with me_cleaner and reflashed and the laptop is running fine.

I might play around with AMIBCP.exe later on and see what's usefull to enable in there.
