Erasing was an issue as well, suppose to be FF all over but I saw some FEs.
I’ve found the root cause, 1.8v adapter is definitely a must. I’ve referred to the guide from within here actually.
After one order placed for the 1.8v adapter and a verify+flash away, my laptop booted!
Thank you so so so much for the guidance and pointers! @lfb6 @68k-dude
I’ve definitely learnt something, rather than just requesting for the BIOS file to be given. Cheers!
