This may setoff virus warnings for you, ignore or disable before you download and use You can’t get full backup with FPT unless you unlock FD First via pinmod, but you might be able to with Universal BIOS Backup Toolkit, try and see (window cannot move, press read, then once it’s done press backup). Please show me image of this error you get > Invalid firmware image > Signature Invalidĭismantle laptop now and get backup made is much better than dismantle laptop later to try and recover with partial BIOS download from the web. If you don’t do that, and have to recover later with stock BIOS only, you can never get NVRAM/VSS back, and it will be a huge pain to find and put back in your system - You have TXE MW FW, you can see that in UEFITool or with ME Analyzer, you need to use TXE V2 FPT, from this thread in section “C2” - Intel Trusted Execution Engine: Drivers, Firmware & System Tools * Edit - I see your edit and raise you > Last resort is fine, but since you have it and you are trying to flash in mod BIOS, I suggest you use your programmer now to get a valid and verified backup made, that way you know you can recover and you know what version software works for your setup. Please be patient, I will let you know once I’ve found the edits on your iscflash.dll (I’m using slow computer right now, so the search within the file is very slow) Why create such a guide, and then not allow discussion!?!? It’s too bad he’s disabled comments on that, I’m sure that would have been discussed and tested at length. I wonder if that method, gets you around RSA Internally Signed BIOS or not, or only the RSA check at the flashing level. However, that does not work on some more recent BIOS, it only causes another error instead, then you can’t get around that one either unless you do the edit via programmer to the onboard BIOS first.
That is a lot of edits though, so on a non-personal level (ie someone making a mod BIOS for someone else) it’s easier to just bypass the secure BIOS check by editing the iscflash.dll
Thank you for the interesting post you linked at post #2 above, although he disabled replies, so you can’t see the amount of success vs failure with that method, it does look valid and proves a long drawn out edit can be done to fix the issue as well. dll - in general, this is done in assembly/hex, in assembly you find the coding that checks and invokes this error and bypass it by either jumping past it, or making it not happen (NOP it out > No Operation Possible > 9090) And the link at the bottom is all the latest version of Insyde H20 tools I can find last year.You’re welcome, please wait, I will tell you how to edit the. I can’t translate the text below precisely because of my poor English, so I just attached the text I once post in Chinese forum written in original language.
