    [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.

              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...

              HP Pavilion Gaming Laptop 15-ec2523nd - Dimm2 slot disabled after corrupt bios repair? Advice requested.
              by Bloodhoundje
              Hi everyone,

              I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

              I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

              After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

              I have desoldered the bios chip (GigaDevice...
