Sure. I have successfully entered the brand name. Just like in the photo.
But every time I start up, the laptop still reports error 2202.
I don't know what to do anymore
otherwise use planar service with your serial

I used the Gold key to re-enter the information but the problem was not resolved.
Has anyone solved this problem yet?
Thanks,

I have been trying to enter Brand name for 1 week but without success. With your guidance, I succeeded the first time.
Thank you so much.

Hello, maybe one of you can help me. I have 2 T14s laptops with board number NM-C891, after soldering the wires and moving the resistor, I still get the message in SVOD 4.
MEC IDCODE: B1240020
Device ID: 0
Device Revision: 0
Device Status: 0
Flash Status: 0000000000
Boot Block in not protected mode
Boot Block in not protected mode
the reading is empty every time. I will add that in the X390, where the board is very similar, I managed to do it every time. Maybe someone had a similar problem ?

I've screwed up a T14 gen1 and now I need to erase the SVP to make it bootable again (0199 System Security error). I'm going to use a Vertyanov JIG V3 for that and I would like to avoid losing all OEM info and windows activation.

just look at the following CON# (43 4F 4E 23 53 00 02 A8 F4) or BC B0 B1 DC AC FF FD 57 0B 02 A8) in Xor version.
Same principle for all, can be doubled on certain models

Hello,
I have RT809F and a damaged Thinkpad T490 board (M2-Connector was damaged and is removed). I use it for testing the procedure of removing the SVP from MEC-Chip. (Yes, I have the SVP.) I do this test because we received Thinkpads T490 donated for our school but they have SVPs. At present they are used. But during summer holidays I hope to remove the SVPs this way.
Typ 20N3001EGE
Serial PF1DTJNC
Bios N2IET99W (1.77)
The MEC chip is recognized correctly. I can read and write the MEC using MEC1633_256. My problem is that erasing of the Chip doest not work.
Does anyone have an idea what the cause could be?
