![]() So I replaced the hex data just like you told and saved the modded bios. REMOVE “,” FROM HTTPS IN THE ABOVE LINK and paste link and folder content like “LinkFolder” in address bar PLEASE SINCE I AM NOT ALLOWED TO POST EXTERNAL LINKS YET AS I AM A NEW MEMBERĮdit by Fernando: Thread title customized Link:ht,t, ps:///drive/folders/įolder: 1cvpZecfjRyj95UCXDFnn1vPArIXu1-ra?usp=sharing Please help me with this as the pinmod is quite a tedious task for me to perform again and again. I am attaching the bios files both modded and unmodded and also the log of successfull flash using fpt. the settings reset option failed many times so I had to recover the bios and now I am stuck as I have no clue what the hell went wrong. When I restarted my laptop after flashing the modded bios, the dell logo appeared and after that it gave me bios recovery menu showing only two options which were either recover my bios from HDD or reset bios setting to default. ![]() Finally I flashed the bios using intel fpt via command “fptw64.exe -bios -f modded-bios.bin” which completed successfully (since FD is unlocked now using the pinmod). I also verified the resulting modded bios file by extracting the efi module from it and using “IRFExtractor 0.3.6” for easy readability. efi module from the old bios.bin v1.11.0. efi after which I used Uefitool v0.28 to replace the corresponding PE32 module in the latest bios.bin v1.15.0 (which I had extracted from my working system) with the extracted. I then opened the bios.bin in “Uefitool NE” and searched for the “overclocking lock” using text search, extracted the body of the respecteive PE32 module as. Now for the modding part, I extracted the bios.bin file from dell bios v1.11.0 exe file using “Dell PFS Extract v5.1” (extracted 5 files from the exe one of them was bios with bios guard). Now since dell has locked the flash descriptor of my laptop (verified using command “fptw64.exe -d spi.bin”) I performed the pinmod (shorting pin 1 and 5 of Realtek HDA chip) which unlocked the FD for me and I was able to read the spi region. ![]() What I did was extracted the bios.bin (v1.15.0) file from my currently working system using intel fpt via command “fptw64.exe -bios -d bios.bin”. So, after spending about a month researching I finally tried modifying my bios. I have searched and read here that enabling “CFG Lock” and “Overclocking Lock” will enable undervolting again. Unfortunately I had already updated long before becoming aware of the situation so now I am stuck with this ridiculus locked bios. ![]() For my inspiron 7567, the last bios version with undervolting enabled is 1.11.0. As you know that dell has patched the plundervolt vulnerability in its computers’ bioses & while doing so has rendered majority of them unable to undervolt. ![]()
