Hi all,

I'm having trouble deleting the SVP on my laptop.
EDIT:
[It's an x280 20KES2SN00; i5-8350U 8GB 01LX681
SN: PC16FNZB 19/07
IC: W25Q128JVSQ]

After flashing the patched file, I get a black screen and a musical note.
The original bin dump is uncorrupted and works after flashing it.

How can I fix the patched file so it works to remove the SVP?

Thanks for your help

Please verify that the chip is erased before patched file is flashed (you could easily miss this option).

Please backup bios with programmer (a hardware device) not with software because software cannot backup the entire bios file.

Hello,
I am trying to unlock my sypervisor pasword on my lenovo e570
At firts i did something wrong and i bricked the laptop, but now i have a working bios that works normally but it still has password. I generated the patch using the method on post#1 but when i boot it gets stuck in the boot screen and any input on the keyboerd does nothing. Reflashong the working bios on the laptop makes it work again but it still has the password. The bios dumb i used is a mix of lenovo's latest uptate bios files, and the clean me region posted on the e570 thread. I post bellow both bios'es(patched+working).

Board: ce570 nm-a831 ren3.0
Model num: TYPE 20H5-S00H00 S/N PF-0MLF40 17/02
Bios chip: winbond 25Q64FVSIQ 1630


(What is shown when booting with patched bios, waited for a long time,about an hour, and tryied every input with no result, stuck in this image)

[chaulong88]

hi try

Thank you very much.
Your BIOS version works well, but I'm currently needing to remove the existing BIOS password.
With the new BIOS version, the password still exists.
Perhaps I have to program the ITE chip

Hello there,
I have a supervisor-password-locked ThinkPad E590 which I tried with the Autopatcher. I dumped the BIOS with my MiniPro but while running the Patcher I get

Using UEFIReplace to inject 2 DXE drivers...
[1/2] BootOption (GUID e0746c42-d3f9-4f8b-b211-1410957b9ff5)
[2/2] LenovoTranslateService (GUID 826bcf56-bac4-43f4-8ea1-8cdf0a121abd)

Looking for volumes to patch...
[1/1] NVRAM_EfiSystemNvDataFvGuid (checksum 2609h):
      Not found... Skipping.

Flashing the patched BIOS I get a black screen on the notebook. Flashing back the original BIOS makes the notebook work again, but with an unknown password.

The machine is an ThinkPad E590 20NB, SNR: PF1L2SCD

Keep the original content safe and write this patched content.
Should boot and follow the procedure described on the first page of this topic.
If all going to be ok then write back your original bios content.
Good Luck!

Thanks. I will report back when I flashed the update. I wonder whats different to following the "receipe" in the download.
