    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...

                Yes, and it's pressed down by adhesive tape...

                Hooray! That's to much for my skills... Are there any other solutions?

                  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:
                  ...

                  Lenovo ThinkPad L15 Gen 1 i7 (20U4) Bios and EC dump needed
                  by Joluvillas
                  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...
