    [REQUEST] Modify BIOS version of dumped image(Panasonic CF-RZ6)

    Hello.

    I keep tried unlocking FIVR lock(XTU, Throttlestop) to do undervolting, but failed. What I tired is...

    1. Unlocked hidden menu >>> Disabled CFG lock, Overlock lock, SGX
    2. Replaced CPU microcode to 2017, 2018 version (pre Spectre, Plundervolt)
    3. Disabled Intel ME, Hyper-V & Vt-d
    4. Removed microcode update of Windows(mcupdate_GenuineIntel.dll)
    5. Try from fresh Win 8.1(boot with USB)

    Even I already did all of above, XTU and Throttlestop is still locked. So I think what I can do is downgrade the BIOS version, but Panasonic does not provide the BIOS image file and gives only installer(I checked with 7z, but there was no perfect image file).

    Is there any way to modify the BIOS version to spoof the installer for downgrade?

    Here is my dump and version is showing as V2.00L30 in BIOS.

          Solved by patching BIOS installer with IDA Free.

              need help to modify a bios dumped from set-top box
              by jason0503
              The set-top box has a TV silicon tuner IC MXL608, which has a programmable channel selection filter (6MHz/7MHz/8MHz), and the default value is 8MHZ, but the manufacturer sets the set-top box to 6MHZ. How can I change this value by modifying the dumped bios? I tried using UEFITool.exe, but it doesn't work. The BIOS of the TV box is different from that of the computer. I don't know how to modify it or what tool to use. I downloaded the data sheet of MXL608, which mentioned that when the value of SYMBOL is set to 2.85, BW=6MHZ. When the value of SYMBOL is 3.75, BW=8MHZ, but I can't find the corresponding...

              Hello everyone,
              i made out of two broken Samsung Galaxy Tabpro S one that works partially.
              The one Mainboard had a broken screen output but working hdmi (usb c adapter) output and the other didnt start at all.
              I switch the bios chips and now the tablet starts but very very slow and it takes some trys to get it starting.
              The problem is, that the micom Version doesn't match with the bios version, see picture.
              How can i update the Micom Version? The Samsung bios update wont work.

              Lenovo Thinkcentre M75n DMI Data extraction from dumped BIOS
              by Kentsfield
              Hi,

              I got a Lenovo Thinkcentre M75n (MT-M 11G5 PF3XG5V3) with a semi-bricked bios.

              Short recap: I want to add an external GPU via the M.2 slot (Oculink). It does work but has some problems with the onboard GPU of the Ryzen 3 3300U. So I used Smokeless_UMAF to disable it. Since then I don't get any video via the external GPU nor the iGPU and Can't access the BIOS, but the PC does boot to the OS.

              I desoldered the flash IC MX25U12872F and dumped the flash.

              I also downloaded the newest BIOS and have it as a .bin file (I loosely compared the contents...

              Asus ROG Strix Scar G533qm with a G733qm Motherboard, can I modify the Bios to accept G533 Bios
              by glovecaps
              Hello,

              I have a Asus ROG Strix Scar 15 (G533QM) that had a dead motherboard (Graphics card dead) and after trying to fix the motherboard with no success, I bit the bullet on a sale for a new motherboard. I ordered a motherboard for the 15 inch model which is the one that I have, and when the motherboard arrived it wasn't for a little while that I saw it was from the 17 inch model.

              My question is, can I update the Bios on this G733 motherboard to a G533 Bios.

              The reason for wanting to do this is that the keyboard isn't working as it should, and I think this...
