Here you go. Try this file

Thanks for your reply.
The original backup dump size is 128ko whereas the file you posted is 256ko (double).
Any new suggestion is welcome.

Thanks for the link. It's very instructive.

it5261VG-256 = 256kb
it5261VG-512 = 512kb

it`s very simple

what`s yours? Make the right choice in my tool ECFinder from the link above and it`ll cut EC firmware automatically from a bios dump or update

Mine is it5261VG-512
I tried with ECFinder_0.5.1 and ECFinder_0.4.7 as well and cmd opens and closes immediately with the error message attached.
I also used Console Mode and got the error message, I attach.
Please help me to overcome this issue.
Also, I would appreciate if you could, from your side, try ECFinder with my above attached EC dump file and post the output file if any. Might be that some DLL files needed are failing in my system, though no specific error displayed.

here you are

main + EC

from official Lenovo T14 Gen 1 (type 20UD, 20UE)

PS no need any additional dlls - working on bare windows7x64+

I used ECFinder_0.4.7 and ECFinder_0.5.1 in windows 10 system and it succeeded but don't understand how to access the saved output file ? Could you please clarify the next steps, the url that opens is in russian language.



Many thanks for the file. I used it but unfortunately no change, superviser password is always requested. I find strange that my EC dump shows 128ko of size, before and after flashing the new dump ?
P.S As EC size is not clearly readable on the chip, I got 512ko from a schematic, I also wrote the 256ko dump posted by mainvod to no avail.

output file in the same directory as it's source file

I think that`s how you read it, not setting manually the correct size of the EC

I revert. Now, I'am well doing with EcFinder after seeing the video. Thanks. It turned out that the correct size of the it5261VG chip in my case is 256kb. So I reworked out the R1BET81W.zip [7.78 MB] dump you posted on the base of 256kb and got a file of 256, whereas the original backup dump file is only 128kb how to explain that ? Is the EC chip failing, not reading the correct size of it's integrated bios ?
