Hi everyone,
I'm trying to recover a Fujitsu Lifebook E5513 (most likely 2023 model) that was bricked during a BIOS update. The update was interrupted (probably due to power loss), and now the laptop is stuck in a boot loop showing "PBB rollback" / "SBB rollback" messages.
BIOS access (F2) and Boot Menu (F12) are no longer possible โ the system instantly reboots after the rollback messages.
I extracted the official BIOS update package from Fujitsu (contains FJNB2FD.CAP, ~18.7 MB) and tried tools like UEFIExtract, but it seems to only contain... -
Hello everyone,
Iโm currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, Iโm at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Hereโs a full breakdown:
๐งฉ Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

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 need a BIOS dump file for my Fujitsu LIFEBOOK AH47/J laptop.
Motherboard model: DAFH6BMB6A0
The system BIOS got corrupted and now the laptop powers on but does not boot.
I already tried the official Fujitsu support site, but the downloadable BIOS is only in .exe format and does not contain the raw .bin file needed for programming the BIOS chip directly with a programmer (CH341A).
If anyone has a working BIOS dump (.bin) for this model, please share it.
Thanks in advance!... -
Hello, my laptop is now completely bricked after updated the fresh install Windows 10 Pro.
It wont ever response to charger and LED completely off after 0.1s
When i tried reflash my dumped with ME clean BIOS and EC extracted from Outimage.bin, LED is now working and battery can charging. But will hard reboot every 3s with WiFi blinking twice, and it can't even turn on.
I tried download BIOS from their website, but the file .UPD (25,6 MB) size is exceed my splitted BIOS (24,0 MB)
Here is my dump BIOS from 128Mb, 64Mb and 8Mb chip. Thank you
