LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

[bigboots]

Hi all.
Has any one got a solution to the auto-patcher tool when it won't save the patched file. It worked before resetting my machine. Now it gets to stage 1 shows the patched file then removes it? Thanks in advance.

The first try didn't worked out and the bios beeped 5x times (wrong checksum). UEFITool revealed the wrong hash:

FfsParser::checkProtectedRanges: Phoenix protected range [BB0000h:F30000h] hash mismatch, opened image may refuse to boot
RelativeOffset: 00BB0000h Size: 380000h
Hash: 894F0EC4AAE777028ADC60150B10ECE724FC165E6530129DD6B56E45623192E6

With the help of HxD i calculated the SHA256 of above range and replaced the old hash with the new one (search the old hash and replace it with the calculated one with help of HxD). A boot with manipulated checksum and patched BIOS binary worked. Supervisor password was removed. Thank you very much!

Hi everyone!

I'm looking for a replacement MB for old lenovo L580.
There are some options to buy one with boot password. Can this tool help in removing it?

I have original motherboard functioning, but with dead charging port -- can be used to read EEPROM.

Oh ok thanks for the response. I thought x260 was on the list of supported laptops for the auto patcher.

The auto patcher used to work fine until i had to reinstall windows. So just thought it was some settings in windows to get it to work again.
Thanks in advance.

Hi , does the patcher work on T540p laptops with two chips? I have dumped the binaries from both chips and tried to patch the 4MB dump and getting error "T540.bin id corrupted or does not contain a a valid dump. There was an error... Aborting." I have read the binaries from the 3237E chip few times and still same error. I had no issue with few other models which I have already cleared the bios passwords on. Thanks
