Hello again badcaps team! In the end I tried modifying the BIOS with autopatch and I managed to create the patched image of my original BIOS, then I tried erasing the original and flashing the patched image to do the password reset according to the steps you have to do in your post of the autopatch manual. Also, now I have some practice and I know how to verify the flashes well and I know when I can have a failure and correct it, and I do all the work correctly, but it turns out that my image patched with the autopath does not work (the LED of the ESC key and the LED of the letter "i"... -
Thanks again, I'll wait for now to see if anyone can confirm if there's a way or a BIOS patch...
Thanks, Moderator SMDflea!!!Leave a comment:

That's true. Thanks again, moderator SMDflea!!
From what I've read in the forum rules post, I seem to remember that the password on these devices was stored on the Nuvotron NPCE288 chip. Is that true? If not, please correct me. If so, then I'm sorry. I'm still learning and wasn't sure. I thought the password would be in the BIOS chip: 25U128. The problem is that I don't currently have a readout of my Nuvotron NPCE288 EC chip. I need to get one to be able to read and dump it, but I still need to look into which one and where to get one. I guess there's no way to do it without the EC chip...Leave a comment:

Hello friends and colleagues! I'm here to ask if you can help me. I have a PC with a supervisor password in the BIOS, and I can't remember it. Could you fix the reading and dumping of my BIOS chip image and remove the password, or offer me a generic image if there is one that might work for my PC? I would greatly appreciate it. I've tried the autopatcher, but it didn't work for me. The information you need:
PC: Lenovo Yoga 11e 5th Generation
MTM: 20LNS0QU00
SERIAL NO.: R9115RSF
MOTHERBOARD: LLA-1 17833 - 1M 448.0DA06.001M
BIOS CHIP: 25U128 (1.8v)
Thank you very...Leave a comment:

Well, I finally got it thanks to you all. I want to thank each and every one of you; Hoaca388, lapfix, danito, and especially SMDflea, who has been very patient with me. In general, thank you all for taking the time to answer my questions and helping me. The problem I was having was a flashing error. I tried several times, but it turned out it wasn't done correctly. Finally, with one of your clean images, it worked. Thanks again to all of you, and I hope to continue learning a little more with your help. A big hug, and see you soon!Leave a comment:

Well, I waited the 30 seconds and nothing, the PC is dead, I'm starting to think that I have no solution, in addition, only the As programmer 2.1. 2 program is the only one that searching for the XMC25RH256C chip lets me do a dump and flash, I tried the Hoaca dump again and it didn't work, after doing the flashing, it decided to check the flash verification and it gave me a data verification error, but the flashing was done correctly, I'm starting to think that I don't know if the original reading I did is correct since I haven't been able to do any other readings, I don't flash with other versions...Leave a comment:

Hi Lapfix, first of all, thank you very much for your help!
I've performed both the BIOS reading and flashing without a charger connected, without the CMOS battery connected, without a battery, and
even with and without RAM installed. I've tried multiple methods, and the same thing happened every time. I press the power button.
The button lights up for a couple of seconds, then it turns off and won't boot. I've also tried the dump Hoaca provided me in post #36 again, as you mentioned. I even tried the dump you provided me again just in case.
It might have flashed incorrectly...Leave a comment:

Please can someone help me? I have a black screen, the PC does not start, does not boot, does not enter the BIOS, and it does not work even when I flash my original dump again, it is something that I do not understand because both my CH341a programmer and the As Programmer and the connection cable between both work correctly, the problem I had when flashing the image that the user lapfix provided me, from flashing that image, I have a black screen, even when flashing my original dump, please help 1, my PC has died, please!Leave a comment:

Hi, thank you very much Lapfix, I have tried your image, I have saved it and it turns out that now the PC does not boot; I press the power button, the power LED lights up but in a few seconds it turns off and no longer shows an image or the logo or anything; it has died, oh my god !!, I have saved the original image from the dump I made the first time again but it does not work either; it does not show an image or enter the BIOS or anything at all... please help me, now I am desperate because nothing works for me and I do not know why my original dump does not work either, what has happened to...Leave a comment:

Thank you very much for answering me hoaca388! I have tried to flash the unlocked files you provided, but when I start the PC and press F1 to enter the BIOS, it asks me for the system password again. Could you help me again? Thanks in advance.Leave a comment:

Hello, could you please help me? I've set the BIOS password on my Lenovo PC and I don't remember it. Could you help me decrypt it, or should I flash my BIOS chip? I'm a novice. If you could help me, I'd really appreciate it.
Model:
LENOVO THINKBOOK 15 G4 IAP Motherboard No: LA-L931P REV 1A S/N: MP2E6NZB
BIOS Chip: XMC25RH256CX
I used the CH341a programmer and AsProgrammer 2.1.2.
The BIOS chip wasn't recognized directly, nor with the Neo Programmer software. It only detected: SPI: 204319
But in the direct chip search, I managed to read it by entering the chip...Leave a comment:
