                          After reflash the EFI still have the same issue. I decided to replaced the CPU voltage regulator U7400 turn on then killed the CPU.

                              Help me verify my NAND dump (attached) from LG SK10Y soundbar stuck in PLEASE WAIT - is it missing critical data?
                              by Daniel Larsson
                              Hi everyone,

                              I’m trying to bring a LG SK10Y soundbar back to life. Currently it is stuck in the “PLEASE WAIT” loop.

                              My conclusion so far is that something fails to boot fully, but it does start via eARC and can play perfectly good sound until watchdog shuts it down.

                              After dumping NAND with a T48 programmer, extracting with binwalk and exploring with Ghidra I think:
                              • Kernel B is present, but no Kernel A. Is that normal?
                              • SquashFS A/B are present
                              • Bootloader is present
                              • UBI region is completely empty (only volume 0 / layout volume exists)
                              • No system.cfg,
                              ...

                              Request HP Proliant Microserver Gen 8 (J06) BIOS dump to restore system firmware
                              by Ahari
                              Hi all,

                              This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.

                              I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

                              I...

                              ASUS ZenBook UX480F : need help with cleaning the ME region of my BIOS dump
                              by mkdj
                              Dear all,
                              I have a ASUS ZenBook UX480F with the following symptoms:



                              I suspect it is a BIOS issue. So I decided to try to clean the ME region. I followed the guide on win-raid, and I believe I have done everything correctly. My problem is: when I open the outimage.bin in ME Analyzer, it says that it is Extracted, and not Region, Extracted as it should be. Is it normal, or did I do something not correctly? This is my first experience editing BIOS files.

                              I would appreciate if someone could take time to explain the issue, so that I can learn. But I would...

                              Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS

                              Hello everyone,

                              I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.

                              This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.

                              I have opened the laptop and identified the main BIOS chip...
