ASUS ROG Ally X - (Handheld Gaming PC)
Model No: RC72LA
Serial No: SBNVKD001014459
Hi all, I've spent the past week digging through the forums and guides to try correct my foolish mistake of changing hidden settings while tinkering around, and to be honest my heads overloaded so I'm hoping you'll be able to help.
I used a tool called 'Smokeless-UMAF' to access usually hidden settings in the bios. I tweaked one or two 'safe' things but made the mistake of tweaking a lot of settings under 'USB/Thunderbolt Configurations' when I didn't know what they did. For example, I changed 'USB4 Bus Reserved' from 96, 'USB4 IO reserved (KB) from 16, 'USB4 Non-Prefetch Memory Reserved' from 384 and 'USB4 - non-Prefetch MMIO align' from 64. I think I also changed USB4 ACPI _DEP Support. Since then it won't boot and sticks on the ROG logo despite resets/battery removal etc.
After finally getting to the point of having a (verified via md5) backup of my bad BIOS, taking the ASUS bios from their site and figuring out how to get it the right file size, I've got the two open in Tiny Hexer and on seeing how much differs between them I'm not confident what I need to copy from mine to the other to make sure all works ok without copying over whatever I broke and maintaining as full a functionality as possible. For example I've read about issues with ASUS cloud restore with a bad bios and I'll likely need to use it after this, and I stumbled across lines in the bios dump mentioning cloud certificates or something similar, so I don't want to make it worse.... I'm feeling a bit 'in too deep'!
I've attached my backup of the bad Bios - from what I gather the serial, win key, and I'm assuming other bits of info I can see in it like cloud recovery certificates etc. all get transplanted to the ASUS bios? Is this the 'DMI' I'm trying to wrap my head around?
Also attached is the altered ASUS bios to correct the file size, removing the first 2KB from the original file. This was downloaded from their site and edited by me in Tiny Hexer. I've put in the untouched bios also.
Thank you for your help
