Any luck?

I ran the bios backup utility again but noticed that it couldn't identify the bios error came up No wonder when the program finished reading the bios, there was no information pertaining to the vendor, type, version, etc. Is there another tool to backup the bios? I'm sure the uploaded file is not useful for you to look at as the bios couldn't be read.

Unpack result file and look :

Error 286: Unable to write data to flash with SPI lock enabled.

It has Eeprom Write Protect !, only SPI Programmer can do this job, so look here :

I extracted Original Bios File AIUU1_X64s_Extracted_92CN30WW(V1.10).rom from Setup and It's Signed and Capsulated !!!
Let me know

Where can I obtain a modified bios for my laptop to flash with SPI programmer tool?

Thanks.

[BDMaster]

First It need to read Firmware from your Eeprom Chip so when You got the Tools
then write to me and I will explain all procedure !
Regards

P.S. I posted all modifies to do at firmware above !!!

BDMaster thanks for the info. Just ordered the CH341A programmer and test clip today. Awaiting for tools to get here and learn some new stuff.

Will update the thread soon.

You can do a test as many times doing (when It's possible) a downgrade then
Eeprom became again Writable !
So do a downgrade toa previous version Bios and then flash this Bios Mod :

I wish I have the resource to an older bios to test this but unfortunately I don't. Guess I'll have to wait until the tools come in to flash the modified bios you provided.
