Is there any way to unlock the CFG-Lock in my laptop, DELL INSPIRON 3421. My BIOS is O14A13 (link: https://www.dell.com/support/home/en-vn/drivers/driversdetails?driverid=dcgmv&oscode=wt64a&productcode=inspiron-14-3421). I've try using the /writeromfile but when open the file with UEFITool (link: https://github.com/LongSoft/UEFITool/releases) but when open it, it shown some errors and when I find the word "CFG-Lock", it shown no things although I can find the Unicode string "CFG". Thanks a lot for reading my article and helping me.
For the turning off CFG-Lock guide that I'm using is here: https://dortania.github.io/OpenCore-Post-Install/misc/msr-lock.html#what-is-cfg-lock
