Hi all, I have a few questions. Any help is greatly appreciated.
I recently bought a Lenovo G505s - Type 80AM (Model: 20255) with an AMD A10-5750M and dual graphics. Windows 8 is installed (for now).
Can only a stock BIOS image be flashed internally on this PC?
Can I flash "83CN53WW_v3.00_clean_BIOS.bin" and/or "83EC53WW_v3.00_clean_KB9012.bin" from https://github.com/g505s-opensource-rese...roprietary internally?
If I want the advanced settings unlocked do I need to flash externally or could the Recovery Procedure flash it?
I just bought a CH341A Mini Programmer from https://www.aliexpress.com/item/32725360255.html for ~$2 AUD but it may take a long time to arrive from China.
The laptop came with
BIOS Version 83CN12WW(V1.01)
EC Version 83EC12WW(V1.01)
and I wanted to update to
BIOS Version 83CN53WW(V3.00)
EC Version 83EC53WW(V3.00)
which is now done but for some reason, I had to use the Recovery Procedure to get the BIOS updated after several apps failed to work.
Fn+R with VALGCX64.fd (and .bin and .rom) on a FAT32 formatted USB stick plugged into the right side port worked for me. I don't know if the extension or USB port matters but it might.
I tried FLASHIT 1.3u that I found on https://forums.lenovo.com/t5/Welcome-FAQ...t/p/278406 but all it'd do is say "Error:Not support AT-p information CL Regisry:0x2"
I then found InsydeH2OFFT_x86_DOS_100.00.08.18 from https://www.insyde.com/downloadcenter on https://www.win-raid.com/t4631f16-Insyde...l#msg76187 which only partially worked.
When I ran H2OFFT-D.exe from FreeDOS it said:
Insyde H2OFFT (Flash Firmware Tool) Version (SEG) 100.00.08.18
Warning
The region map shouldn't have duplicate region type within.
Initializing
Error: The region map has no end type (0xFF).
Current BIOS Model name: INVALID
New BIOS Model name: INVALID
Current BIOS version: 83CN12WW(V1.01)
New BIOS version: 83CN53WW(V3.00)
Dangerous! Do you want to flash BIOS? (Y/N)
I decided to press Y and then it updated the EC but not the BIOS.
Even the official Lenovo Windows flasher "winflash(3.00).exe" wouldn't update the BIOS, it showed the BIOS Version as INVALID, the EC Version as 83EC53WW(V3.00) and an error message popped up. What could cause these errors? Could it be a bug in the BIOS (versions prior to 2.05 have a CPU bug for example)?
