@solomonenakele - please edit your posts when you need to add more thoughts and no one else has replied yet, thanks How do you have identical laptop with different model? 571 and 571G are not same, so I may not be able to unlock your BIOS, I will check. Thanks for letting me know which your BIOS ID is, but since you have dump provided I don’t need anyway Do you want this exact old version BIOS you posted unlocked, or do you want to update to 1.33 first and then send me new dump?
I just unlocked latest BIOS 1.33 for this model here, for your reference and anyone else later too (Since unlock was never confirmed in this thread by the OP) Don’t use that BIOS, only linking for confirmation of unlock OK Microcode Update of Insyde UEFI BIOSes
Can you tell @winactive how you removed the locks so you were able to FPT flash, thanks Or, maybe it’s only possible for you since you are on old BIOS and you didn’t have to do anything special?
@solomonenakele - thanks, I suspected it may be due to older/different version BIOS, thanks. Sorry Winactive, I figured it was that I checked, and this BIOS is only 1.32, so not really old compared to 1.33, but I didn’t compare dates so may be older than version seems to indicate. And, as I mentioned before, this is not same model, his is the A5WAB BIOS, so that must be the reason the security locks differ.
So this is what I did. *Restart ur pc 1. Open Command Prompt 2. Dump ur Bios with command "FPTw.exe -bios -d biosreg.bin" 3. Send it to @Lost_N_BIOS (awesome bro.) to unlock for you… 4. Flash it with command "FPTw.exe -bios -f name-of-modded-bios-file.bin" That’s it… It ought to work at this point. But if you run into 280 error like I did… try the following. 1. input the flash command on cmd (“FPTw.exe -bios -f name-of-modded-bios-file.bin”), but don’t press enter yet. 2. put your pc to sleep(not shutdown or hibernate) for 5mins or more. 3. when you wake your pc, the first thing you do is press enter on the cmd and it will flash successfully…!
This method sounds too easy and less techie buh, it was how i got past the 280 error
note my bios version is 1.32, windows10 1903 (may 2019 update) intel core i3, 12gb ram. am on secure boot uefi
If you run into any problems with “audio device not found” just restore default in bios and it should fix that problem.
Pls for anyone to try this… do let us know if it worked for you or not…
Special Thanks to @Lost_N_BIOS for unlocking the 1.32 bios… It works…!
I know BIOS lock is enabled by default, but if I knew you had this issue I would have modified that also in the mod BIOS I sent you, so next time around it would already be unlocked. Sorry I didn’t think to check since you said no issues previously flashing
And yes, some BIOS have the S3 security sleep bug, thanks for posting that here for others! And thank you for the how-to guide for others as well
@davidm71 - for many Insyde unlock, this guide will help get you there - http://web.archive.org/web/2016111807325…power-tabs.html I hate Insyde BIOS, so it’s not my usual thing and I can’t easily write out a guide or anything like that. If you are familiar with IDA I can show you were the edits are done in the IDA flow charts, but once you find this it’s only a two byte edit in hex on the setup module body (one for each menu, to not bypass/lock them)
Here’s the actual edit done on the BIOS above Section_PE32_image_DriverSampleDxe_SetupUtility_body.efi 00000000000014A9: D5 >> Change to >> 00 00000000000014DD: A1 >> Change to >> 00
As for AMI, I’m not sure what you mean there? But generally, no, I’ve not found any good modification info for AMI, that bit you see in my guide on Tonfang is best modding info I know for Aptio V, Aptio IV can be similar to that method a little bit sometimes, but usually it’s more setup module edits or AMITSE/SetupData modifications (AMIBCP)
I meant in regards to non-insyde type bios files. My interest in this topic is purely academic. Want to learn. I appreciate the links you have provided and will check them out! Will also PM you later… Thank you.
Yeah, not too much good info out there in once place or in any guides that I’ve seen for AMI If you find some on modern AMI let me know, I like to learn BIOS mods/methods too, thanks! Rebelshaven is a good source for old AMI info, but it’s hard to find good links to archives of many pages there now.
@shino246 - what BIOS did you flash? Sounds like you maybe flashed someone’s BIOS that has password on it? You can try this password and see if it lets you in to then blank out current pass Insyde H2O BIOS (Acer, HP) - 31758401
@minhquang47 - I can and have unlocked your BIOS, but you need flash programmer to dump BIOS and send to me, then I edit and you program back. You need CH341A + SOIC8 test clip with cable, if you need linked examples of these items let me know.
