Hey guys, is there any guide covering the subject? I got few iMac A1418 eDP LCD's some of them cracked glass and working and 2 whole, but no display (backlight ok) I guess it's worth trying to mess around the eeprom's.

Re: EDID dump/write over i2c with raspberry pi
Is EDID stored in SPI memory and somehow interfaced to i2c or there is i2c memory module I cannot find? in EC?
Hooking raspi pi to panel now, will update if find something.Comment

by Habble7The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

by MephysisHello guys i really need help, i recently updated my DS-7208HGHI-K1 and it somehow got bricked, I've got it up and working now by flashing a new dump file i found but the serial number is really wrong and the uploader of the dump file probably intentionally did it.
I still have the bricked dump file is it possible to transfer the serial number of the "bricked dump" to the "working dump"? -
by hyperwoodHi everyone,
Iām looking for a 2 MB BIOS dump for a Lenovo IdeaPad 5 16ARH7H / Legion 5 with mainboard NM-E471 Rev. 2.0.
The BIOS chip is a Winbond W25Q16FW (1.8V, 2MB) and it's completely unresponsive / bricked. I tried recovery via USB but no success. Now I want to reflash it externally using a CH341A programmer.
I already found 32MB dumps (e.g. from Vinafix and Badcaps), but they are too large for the chip ā and the last 2MB in those files are just FF FF FF....
ā What I need:- A working 2MB BIOS dump
- Matching NM-E471 Rev. 2.0, e.g. JY575
