Hello all, I recently flashed a custom BIOS for my HP 6730B provided by Maxinator from BIOS-MODS.com in an attempt to enable dual-IDA mode to increase my CPU clock, however apparently this BIOS was untested ended up bricking my laptop so now I need help restoring it, and I haven't gotten any help from that website. I initially tried creating a USB recovery drive but the laptop would not initialize BIOS recovery. Next I tried using the Win+B and Win+V commands, but neither brought up the BIOS recovery utility. Next I decided to see what I could do with my CH341A, so I disassembled the laptop and hooked up the chip to a separate laptop. Upon reading the chip with ASProgrammer, I was able to confirm that the custom BIOS provided to me was flashed correctly by comparing the BIOS file to what was in the custom bios sent to me. I next tried to wipe and flash the EEPROM with the original BIOS, however it appears that the EEPROM is stuck in Write Disable Mode, so although I was able to erase the custom BIOS, I cannot reflash the original BIOS. Using "Unprotect" in ASProgrammer does not unprotect the chip. Checking the status registers for my EEPROM (SST25VF016B) confirms that WREN (Write Enable) is low (0) and writing is disabled. According to the datasheet for this EEPROM, Writing can be enabled by sending the hex code 06 to the IC, however it's not described how to send this code in the datasheet. Does anyone know how to re-enable write mode on this EEPROM? I have a few of these laptops, so I tried this BIOS again on another one, this time I removed the CMOS battery beforehand, and still bricked, I'm not sure what else to do here, it doesn't seem like there is any way to reliably purchase another one of these EEPROMS to replace the current ones. Any help is greatly appreciated!
