can someone assist me here? I put the original and unlocked roms on a usb drive, i booted into efi shell but when i press fs0, or fs1, etc  get ‘fs1’ is not recognized as an internal or external command, operable program, or batch file. what am I missing?

sorry, figured it out fs1: is the command lol. thanks everyone!

new question, i can see my usb drive from uefi shell but it has no alias attached to it (null), how do i mount it so I can see the contents? I cannot get to the bios rom on the usb drive.

UPDATE: took a chance and flashed it from the emmc drive. all went well, I have advanced options now. however, I disabled the cpu power management but my TDP in HWInfo still shows 6W. What did I do wrong or is this setting just present in Bios but has no effect?

sorry if i miss something but, what is “embedded controller (ITE)” ?

I received a “claimed good” Samsung 860 Evo ssd 250 Gb , chances of detection are better with bios but it doesn’t works better than Crucial MX500 when Win 10 boots up.

I just received my 1.8v converter, I will try to dump bios at 1st.

If it works then I’ll try to change ahci bios module with the one from Ezbook 3L sourced by @Chupa so please @Giovanni , do you think i should extract and replace ahci module “as it is” or “uncompressed” ?

best regards

Long story short: failed bios update, tried to flash bios with external prommer but flashed wrong chip ? Now I have two eprom chips on ezbook motherboard with wrong bios…

Success, use CH341A (without adapter 1.8V !) + Colibri (GD25LQ64)

1. read

3. write
4. read (for check crc32)
