Hello everyone,
I’m urgently looking for a full BIOS and EC firmware dump for the HP Omen Transcend 16-u0000sl laptop (Product ID: 949A4EA).
My BIOS chip is a Winbond 25R128JVSN, and the motherboard has a single 128Mbit (16MB) BIOS chip.
After a system update and an attempted USB recovery, the system bricked, and I had to use a CH341A programmer.
I’ve tried several official versions, but I now need a working original or modded compatible dump, including:
EC firmware
UUID/NVRAM (or neutral values)
Microcode compatible with Intel 13th Gen i7 + RTX 4070 Mobile
If anyone can provide a working dump or a reliable link, I’d greatly appreciate it.
I can also share my corrupted files for comparison.
Thank you in advance — any help is greatly appreciated!
Use HP files from current or same version of the system before updating and try to reconstruct the firmware/regions… as i suspect it won’t be easy to find dumps from this system.
08BB3 or 08BB4
EDIT: Corrupted vs Rebuild
Hello, I tried transplanting the BIOS region from 08BB4 onto my corrupted dump using UEFITool, and I populated the various DMI fields (feature byte, serial number, SKU, etc.). After flashing it, I did notice different behavior: with the corrupted dump I had the Caps Lock blinking two short and two normal times (I think the BIOS is corrupted). Now the PC powers on; after the flash the screen backlight comes on, then it goes black and the system reboots twice with a black screen and then shuts down. I’m attaching my dumps in case someone can take a look and see if I did something wrong. Thanks in advance for your time.
It looks to me like the two non-highlighted entries — InsydeH2O flash device map and the branch 7d5fdcf6…etc in the corrupted BIOS — might be the result of a failed update, which could have left them behind as duplicates. Could this be the case?
Tanks for your time
