Re: mec 16xx dump with info block
I looked at my file and you’re right there is more info at the end that was cut off.
On mine the cut off was just blank padding no content so likely why it had no effect.
So the 256k would be a better option.
Depending what MEC chip your Reading the size may be different....Leave a comment:

Re: Need ThinkPad Config Information Update v1.02 or Lenovo Maintenance Utility V2.02
I had same issue, from main menu I think it' option 3, set product name.
Name should be “Lenovo ThinkPad T14s Gen 2” or “ThinkPad T14s Gen 2”.
The tool I think automatically adds the first “thinkpad” part when entering the name of you let it....Leave a comment:

Re: T14s - MEC-1663 - Jtag - Pinout - Bios Password Removal
Did you try to remove the charger, bios and main battery after erasing chip.
Let it sit for 5min then reflash and boot.
Also it's the same chip but maybe this model the password is stored in the bios image. May have to manually edit it out or try the Lenovo bios unlock tool....Leave a comment:

Re: Lenovo MDM - Windows Autopilot
I did not find a way to remove the Oa3 key, as a work around I found you install windows on another machine, then bring the SSD over and do offline activation before connecting internet it skips the auto windows activation and never reads the OA3 key.
But if windows ever deactivates it may start the enrollment when it reactivates. And if you reinstall you’ll have to do the same process, cannot install directly as windows install force reads the OA3 key....Last edited by SMDFlea; 06-12-2023, 02:54 PM.Leave a comment:

Re: Lenovo MDM - Windows Autopilot
Changing serial, HW id, uuid have no affect.
The key that needs to be changes is the os3 key but it’s a .cfg file how do we change it?
I tired Oa3 tool from windows sdk it said couldn't install drivers I installed them manually as they extracted into the tools folder but still the same message.
A workaround is you have to install windows from another Pc, bring SSD back, install and activate windows offline with a new key. If you do online activation it will force check for that os3 key and start the...Leave a comment:

Do you happen to have the board view to go with it "NV-B141 YD1KL-3 BoardView"?
