Re: LG C500 2 sec shuts off
I optained the file for LG C500 Pegatron H46Y rev 2.1 from Another website and proven to be working according tp replies. Check if you have the same model as above. The model name is given as file name inside RAR file. If your MB has Another name/ rev then it won't work. How did you flash the EC??
Would recommend trying another bios chip and flash it with a known good programmer.Comment

Re: LG C500 2 sec shuts off
Thanks for the response tibd at first i flashed the main with your file laptop turns on automatically fan spinning fast but no display after that i flashed the EC with your file because the same size with my original 64kb i flashed with miniprotl886cs programmer and soldered back when i plugged in laptop nw no power and led lights.it is possible the ec problem?i checkex the motherboard is the same with your file H46y rev 2.1.Comment

Re: LG C500 2 sec shuts off
Main bios is winbond W25Q32bv and ec is mx25l512 i checked the voltage on this chip voltage is correct. I dont have another the same chip to replaceComment

Re: LG C500 2 sec shuts off
I had a pair of these 25q32 failing. they seemed to be programmable but never worked, changing them revived the MBs, just a though that it might be so but very hard to say. As i mentioned the dumps are not from som device i own but from a very good website that i never had problem with.Comment

Hello everyone,
I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details- Barebone / Chassis: TongFang GK7MRFR

Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder... -

Product Name: Razer Blade 15 (2022)
Product ID: RZ09-0421
Motherboard: CH580
BIOS Versions I work with: 2.02 & 2.06
Bios File Size: 32,768 KB
Dear Forum Readers!
I'm looking for a BIOS modder or anyone with experience who would give me suggestions about my razer blade's BIOS settings.
I can view and edit the content of the BIOS .bin file with AMIBCP BIOS editor.
The BIOS files I'm working with are from badcaps.net and those are CLEAN BIOS files (anyone can find it with the search string: RZ09-0421).
