Lenovo G570 Rewrite InsydeH2O BIOS from USB
#1
Hello BIOS-Mods Community! I am romanian.
I own a Lenovo G570 laptop. Two days ago I flashed BIOS with  NWL (NoWhiteList) and ADV (ADVanced menu unlocked). All thinghs ok until I went to Video Config and set Primary Display from SG to PEG. I thought that PEG is abbreviation from PciExpressGraphics, but I discovered it comes from Peripheral Graphics. Since then, BIOS can't see my video card and can't boot, can't enter in bios, can't nothing, only black screen.
 
Things I tried:
1. Reset CMOS with CMOS battery method. It reset only the BIOS password, not entire BIOS settings.
2. I followed this tutorial https://www.bios-mods.com/bios-recovery/...-recovery/ ; Andy P’s SLIC tool from My Digital Life results that my BIOS recovery file name is "PIWG1.bi?". I downloaded the original BIOS for G540 and G570 from Lenovo site, extract it with 7zip to find BIOS bin file. I renamed PIWG2219.bin to PIWG1.bin and I placed it in root of 4GB stick FAT formated with 64kb.
I took out my DVD and HDD.
If I put only the HDD back (without DVD, USB or alimentation battery inserted), when I start laptop normally, at normal fan speed, it beep once. So laptop can see HDD. I took out HDD.
If I insert in laptop only the the USB stick, it beep once. So laptop can see my USB stick.
I keep in lapto USB stick. I keep out of laptop the alimentation battery and the power cord. With these two disconnected I hold Fn+B. I reconnect only the power cord. I press the power button. The fan goes to maximum speed, so it obviously go in recovery mode or something.
Now in BIOS recovery mode, at maximum fan speed with USB stick inserted, laptop not beeps, LED on USB stick lights up so it reads the USB stick, but THE ONLY PROBLEM is that cannot find the BIOS recovery file. I waited 30+ minutes, but unfortunately nothing happens.
 
I think maybe the recovery file name is wrong.
 
Please help me. I don't want to buy a new motherboard because it obviously can be recovered, but I don't know the recovery file name. On internet, it's no such of case for g570 or g540. It's for g550 but the case is totally different because the BIOS isn't InsydeH2O, it's Phoenix and the bios file is in ".wph" format, not ".bin".
 
Anyway, any small help would be appreciated.

here You go (Camiloml suggestion to use Recovery) :

https://www.bios-mods.com/forum/Thread-R...9#pid42719


*******************************************************************************************

Do this.

Rename the ROM file to PIWG1.bin and place it on root of FAT32 formatted pendrive.
And flash it by recovery holding FN-B with pendrive inserted and while you press power on on laptop
(from powered off state)

From another G770 user

1. turn off the laptop
2. Unplug the power cord.
3. insert the flash drive
4. press and hold Fn-B key combination
5. while holding Fn-B, plug in the power cord
6. still holding Fn-B, press Power button
the computer will spin up the fan but the screen will remain black.
If it finds the appropriate file, it'll beep again, read it in, and will start flashing the BIOS.
Once it's completed flashing the BIOS, it will continuously beep, the power button will not respond,
neither will any key combinations (Scared me at this point, thought i bricked my motherboard).
I unplugged the laptop from the power, pulled the battery to kill the laptop.
Once I put the battery back in, I hit the power button and it powered up and ran without issue.

Hey and thanks for the good work Camiloml.
It works like a charm;D

***********************************************************************


So this way is tested and wroked, i hope It will work for You but I know that
NVRAM is emulated into Firmware Eeprom Chip so It will remains like DMI data !
If You will not Recover your laptop then only way is rewrite manually by SPI PGM
the Pure Firmware without the wrong Video Settings !

Hi there! Same problem, almost thought I killed the laptop.
Found out how to fix it, and voila! A ready guide with all necessities inside!
You would need CH314(A) programmer from AliExpress (or Temu) and NeoProgrammer.
Link to a .zip file with BIOS images and the guide:
