    ThinkPad T460s bootloop - BIOS failflash

    Hi everybody!

    I've tried to flash a T460s with the modified file by maxpower3 to remove the bios lock. Sadly somethings went wrong, the T460s won't start now, played to much with the bios dump and bricked the ThinkPad...

    Now it's in a boot loop (0,2 sec on - off - 0,2 sec on - off.....). Can anybody please have a look on it what's wrong with this acutal dump file?

    Thx!

          Thanks a lot for your efforts @hoaca388!

          Sadly the dump brought no improvement - still remaining in the boot loop. Maybe the original dump from this machine could help. I've tried to flash it back - but also no success. It must be a problem with the TPM or Intel ME I think...

                  Thanks again, sorry to say, that the Thinkpad is still reamining in the bootloop. Any ideas left?

                                  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...

                                  I need a BIOS dump for the Samsung S49CG934SU monitor
                                  by Habble7
                                  The 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.

                                  Troubleshooting Attempts:
                                  ...

                                  Hi all! I was reading on tutorials how to flash a bios to remove password from a bios, and I ended up reading the EC chip instead of the main bios chip, it only gave me a .bin file of 1,024kb, I learned later that that is the EC chip not the main bios chip (I should have read the tutorials here instead before attempting anything, my bad), I went to flash the original backup, the 1,024kb size file into the same chip and laptop is not powering up anymore. I may have screwed the chip or even the motherboard (Hopefully not), I am trying to see if there is a fix before I discard it. I had a couple...
