Xbox Original Bios Mod PCB Is

Yours appears to be missing a switch and socket however, so it might be a clone.

Firstly Id try flashing with XBlastOS, as that supports the widest range of chips.

Just upload the BIOS file you want along with the XBE, open the XBE on your Xbox and browse to select the BIOS to attempt a flash.

If not, youd probably have better luck carefully removing the 49LF020A chip from the PCB with a needle and plugging it into an external flash programmer to do it from PC.

I always remove the logo personally- you can do this using EVTool.

As your Xbox is a 1.6 your options are limited, so M8 is probably best, make sure it has the 1.6 variety with LBA48 support.

Because it does not support every flash chip, there is one of two possible problems: 1: the flash chip is not supported, thus it is coming up with the manufacturers ID as FF and device ID 00.

It is possible your mod PCB is wired in such a way to avoid the flash being writable.

As documentation is lacking for this PCB youd need to take the flash chip itself out (labeled 49LF020A) and reprogram it externally if this is the case.

Thats why I suggest running XblastOS to try flashing with that first, since it supports more chips than EvoX-Dashboard.

I opened it and saw that it even wasnt EvoX, but UnleashX (idk why).

I need help which files to remove that are part of the unnecessary dash (I wanna keep the folders: Alt Dashboard, Applications, Backups, CACHE, MP3, PICS, TDATA, Trainers, UDATA and Video).
