Re: RCUnlocker

Thank you @hoaca388 but given your previous response as well as for @RethoricalCheese is it worth flashing this one on the 32MB chip or should I address the 16MB one with RC Unlocker ?

Re: RCUnlocker



RC Unlocker will not work 32MB files.

I need to work *both* the 32MB and 16MB BIOS ?

Soldering the MX25L12873FZNI seems a million times more difficult than the W25Q256JVEQ 8\

I am close to giving up 8\...

Re: RCUnlocker

Finally managed to get the CH341 programmer, read the BIOS twice compared OK used HPUnlocker, wrote the BIOS back and this is when things start to get messy...
Comparing _unlocked.bin with BIOS there are differences:
[CODE]
01B01CA2: FF 01
01B01CA3: FF 00
01B01CA4: FF 00
01B01CA5: FF 00

Comparing original BIOS with _unlocked:

01B01C9A: 02 00
01B01CA2: 01 FF
01B01CA3: 00 FF
01B01CA4: 00 FF
01B01CA5: 00 FF
01B01CAA: 64 00
01B01CAC: 65 00
01B01CAE: 66 00
01B01CB0:...

Re: RCUnlocker

Well found myself doing poor life choices and getting a BIOS locked HP 640 G4... because I currently do not have and EEPROM reader/ programmer (already ordered one) and find myself terrified for unsoldering it, and I have electronics background still, tried killing of time and managed to extract the EEPROM with a tool found on Major Geeks, BIOS Backup ToolKit V2.0 to "fool around" with RCUnlocker.
Well RCUnlocker seems to work the file fine, in the end the splash screen display correctly the information for the machine.
Went comparing the two...
