Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal


Hi,

An update-
The LED blink seems to be an indication of fried MB from what I read. Since I did not use any glove/anti-static measures, there is a chance this may have happened (or the chip somehow got messed up).
So- I kept it aside and picked up the second laptop. Same model- Gen3, 20BT.
Followed the instructions from this post- [url]https://www.badcaps.net/forum/showthread.php?t=87588[/url]

Everything went fine and now I have a TP, with a BIOS that doesnt have SVP....

Hi,
So, I sorted out the Ch341 voltage and took a BIOS dump from another working X1 Carbon Gen3 (20BS). It has SVP, but does boot and load the OS.
Used this BIOS to flash the bricked laptop. This time, I took the whole motherboard out and disconnected CMOS while flashing. Still no luck. On power up, all I get is a quick fan spin and the same 4 LED blinks on the power button (that repeats for the eternity as long as the power lead is connected). Resetting the laptop hasn't helped either.

Hi All Members,
First of all thank you very much for all the information shared. Its truly remarkable.
I have a Thinkpad X1 Carbon Gen3 (touch screen - 20BT) that had a supervisor password, which later I managed to brick rather ingeniously. System would start POST (fan spins up and KB lights comes up for about 3 sec and dies).Since I haven't had a back up copy of the BIOS, this is what I tried so-far
1. Downloaded a generic copy of the BIOS (size did match up with my chip- 16384KB)
2. Flashed...
