              Try writing only this file, then reset all security-related settings (inclduing FP)

                  Hi Sparo, thanks for the file.

                  Ive flashed the chip out of circuit on a t48 with success, also verified it.
                  when i soldered it back its still the same, 3 white pwr led when the power adapter is inserted.
                  Maybe any other tips?

                  Any help will be gladly appreciated, im out of ways

                            not working thanks for the try, if you can check once more if this is correct so i know that the bios is not the issue.

                              Panasonic LED TV Dead after EMMC dump
                              by BigPete
                              I recently took a dump of the 4GB EMMC dump of a new and working Panasonic main board and now the TV won't turn on.
                              The dump was successful and the program finished without errors.
                              I used a XGecu T48 to do the dump.
                              I actually had a few issues getting it to go and I might write up something as a bit of a guide as I couldn't find much in English to go from.
                              One thing I did do was connect a 1kohm resistor from the 1.2v line to the RSTN pin as per the instructions, could this have caused issues?
                              I also shorted out the crystal of the adjoining ECU together and at one...

                              Lenovo X1 Carbon 7th Gen Type 20R1 BIOS DUMP

                              SN: PF1Y5BBJ
                              Board: GX490 NM-C661 Rev: 1.0

                              I have made two dumps of this bios, with the bios chip removed from the board and the hashes match on both dumps, but I cannot find the DMI information in the dumps except for the Windows product key, so I think it is corrupted. I have downloaded two bios updates from the Lenovo support site, but they contain small .PAT file, and 4 subfolders containing .FL1 and .FL2 files, which I don't understand enough to figure out how to use to fix my dump.

                              The problem with the laptop is that...

                              Monster Abra A5 V19.3 - Tongfang GM5AGFO MB V1.1 - BIOS Dump Clean ME Request
                              by s.izadbakhsh
                              Hi everyone,

                              I need a working BIOS dump for a Monster Abra A5 V19.3 laptop.

                              Here are the motherboard details:
                              • Model: Tongfang GM5AGFO MB V1.1
                              • CPU: Intel 12th Gen (Alder Lake)

                              The laptop is currently in a boot loop (turns on and off immediately). I have desoldered the SPI Flash IC (GigaDevice GD25R256DYIG) and read the original 32MB dump.

                              Note: I have already tried testing another BIOS dump found online, but the laptop behaves exactly the same (on/off boot loop) with both the original dump and the other file.

                              Could someone please provide...

                              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...
