[REQUEST] Asus A550JK & K550JK & X550JK BIOS Unlock

Well at least you have local place to RMA to quickly then, that makes RMA easier, tell them it died on reboot after "Some Asus Updates via auto-updater" that way they can't blame you for bad BIOS flash.

Yes, if after that bad flash went in (After the size warning and then flashed anyway), and you did not reboot, then you could have reflashed your original FPT dump and it would have been fixed. No Winflash tool to be used here.

Mhm, but I think it's safer to use winflash and flash the original bios from the asus support site. Makes me feel more comfortable to see a ui than command prompt interface.

But yeah, thanks for being here with me and providing help!

That may or may not work, in the situation we are discussing, but you'd only find out if it failed after a risky reboot. Proper way would be to reflash the original dumped FPT BIOS region, but it's very hard to know the outcome since I did not see the original command, the original error and then the final message.

What I was mainly confirming on your question, in a normal situation where you dumped a BIOS region, edited it, then flashed back via FPT, but knew it would brick on reboot due to some error or you noticed bad edit in the BIOS etc, yes, before a reboot you could write in a proper BIOS region again via FPT before rebooting and that would fix any possible mistake the first one caused since no reboot yet.

In your particular case, it may or may not have mattered, due to the "Size error" you got that mean you either did not write to the BIOS region, or you wrote in more than the BIOS region (So wrote over some other region also). So following that with a proper BIOS region re-write may not have fixed it, due to the other non-BIOS region areas that were written to following the "Size error" and you saying "Yes" to flash anyway.

GUI only does the CMD line stuff in the backround, same as you would do in a CMD line. Let me know once you get the new system going and we can try again, this time you stop and take image on any and all errors and do not move forward until I say OK

[shong57]

As an answer to the "flags" I added into the command, it was exactly the ones you instructed me to type in; flashing only the bios region. And the size mismatch error pops up after I flashed the modded bios dump.

And yeah, I'll be slower this time. I was too quick and excited that time.

You can't get size error when flashing same size file as the region being flashed, so something was wrong there, mistyped flag, or some issue with using FPTx64 possibly, some Win10 issue etc

So, I got the laptop fixed. Should I try doing it again? I'll first test original FPTw by making a dump of current bios by the way. I'll let you know what happens.

EDIT: Here's the result when I tried using 32-bit fptw.

   

[shong57]

Hmn, well, after thinking a lot for quite some time. I have a question. Am I able to verify the bios bin first before flashing it? The fptw seems to have that command, I tried using the flag "-help" and it came up with a lot of flags for me to choose from. And there's one related about verifying, it's "-verify"

Sorry for the long delay though, I got kinda shaken up from the bricking last time. 

[Lost_N_BIOS]

Ahh, so a crap Win10 issue, not a FPT issue! Do from DOS instead then, it's better doing that anyway, then you don't have to worry about 32/64 bit, nor running CMD as admin or having ME FW drivers installed.

The verify function from FPT only verifies the file it dumps (right then) vs the same contents it dumped from, or verifies that it wrote what you gave it.

If you get size error again, don't reboot the system! Show me image of command entered and error all on same screen, then leave system as-is without rebooting until we can correctly flash it.

No worries about long wait to reply back, I know that feeling too You can save yourself from that stress by ordering Ch341A + SOIC8 test clip w/ cable, total cost shipped $6, let me know if you need some linked examples. A set of those will save you from any future bad BIOS flash, and it will also allow you to flash in anything you want, anytime, without restrictions

[shong57]

Mhm, okay then. But how do I get the DOS version to work? I don't know how.

But still, I got some picture of me trying to verify the bios dump you made for me. And the size mismatch only shows when I tell it to verify the one you made. The normal unmodded dump is fine though. I don't think it's FPT problem, but if it is. I'm fine with doing it the other way, just wanna make extra sure.

Boot to DOS on USB, here's how to make bootable DOS USB if you don't have other preferred method
Win98 SE USB Boot (Follow steps 1-4 to create bootable USB)
https://www.win-raid.com/t3756f16-lt-Req...l#msg53541

Once you've created that, copy all contents from the FPT DOS folder to the root of USB (nothing in folders), and a copy of your original biosreg.bin and the mod biosreg.bin file.

I don't see any Size Mismatch errors there, only Data Mismatch in those images, which is expected since you are comparing mod BIOS with current BIOS contents
