Vesko,

Author of this topic ask about password and how to recover it. Seems he made a post in wrong part of forum, as he didn't made bios request, but password removal help.
I continue discussion of how to remove password.
I didn't upload bios file at all, so i think this is missunderstanding.

This topic is about Lenovo Thinkpad L15 Supervisor Password removal, if your request is about this model OK, if not you are off topic here, that's why you must provide the data I've asked for as per the rules.

So did anyone had any luck using SVOD4 or vertynov?

From SVOD i keep getting empty reading and cant write or erase or verify.
Has anyone had any luck?

SVOD and VERTYANOV are proofreading the firmware, ABOVE POSTED A CLEAN, READING CONSISTS IN THE CORRECT CONNECTION !!!!!

Re: Lenovo Thinkpad L15 (CPU 10th Gen) Supervisor Password

Re: Lenovo Thinkpad L15 (CPU 10th Gen) Supervisor Password

hello friends, first you have to do is update your svod4, ask the manufacturer for that, second the steps are in the note, and third you have to connect the battery and charger. I leave the clean files of the ec.

Why is the extracted EC file not 256kb?

Re: Lenovo Thinkpad L15 (CPU 10th Gen) Supervisor Password

does reading from svod 3.0 work for you ?

Re: Lenovo Thinkpad L15 (CPU 10th Gen) Supervisor Password

Re: Lenovo Thinkpad L15 (CPU 10th Gen) Supervisor Password

I found a Vertyanow successor NM-C631 KB_pins=40 LEFT DOWN 05MM FLASH=256 JENK=7 TCK=13 TMS=11 TDI=14 TDO=17 CHIP=NPCE68APA0DX 0x0FE2201F (evserv)

This will allow to connect using RT809H?

Re: Lenovo Thinkpad L15 (CPU 10th Gen) Supervisor Password

yes, with svod4, you have to update to be able to read that ec, it is also 256 not 128. in the end I was able to do it.

Can you please upload full config and connection from SVOD?
