I have successfully removed EC password. The system has received complete information. But when starting the laptop there is still message 2202: Product name is invalid.
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 ?Comment

Hey Maxpower3, I've noticed that you've filled with F the blocks from 0x300 to 0x34F. Is this all it takes with all MEC1663 to erase SVP or was this something specific for this user's laptop?
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.Comment

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 modelsComment

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?

I have SVOD4, I can read and write it5679-1M chip for the P14s gen 2, nm-D451. Can someone share the file for this chip ?Comment

Hi,
My laptop has bios password.
Thinkpad T490S FT491/FX390 NM-B891 REV 2.0
S/T: MJ-0C3ABP
Here is bios dump. Please unlock it.
Thanks,...Comment

There is no difference between your uploaded MEC content and the factory one (attached)...they are identical.
The password is stored in the 2K EEPROM inside the MEC.
There are programmers (like SVOD 4) that can read the eeprom content separately and then you can delete the password.
If you don't have such a programmer you can simply erase and reprogram the whole MEC1633 and after that reinsert the DMI info.
This is my opinion.

by Habble7The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

by MephysisHello guys i really need help, i recently updated my DS-7208HGHI-K1 and it somehow got bricked, I've got it up and working now by flashing a new dump file i found but the serial number is really wrong and the uploader of the dump file probably intentionally did it.
I still have the bricked dump file is it possible to transfer the serial number of the "bricked dump" to the "working dump"? -
by Andreas_deHello!
i got a damaged Manson NTP-5561 (60V, 1,6A DC output) and and the main issue is that the controler IC for the LCD display has a short. The controler IC PIC18F87K90 is mounted on the back of the back of the LCD. Vss-Vdd = 3 Ohm. The 5V and 3,3V power line was killed as well, but that is not a problem. A new LDO 3,3V and 5V 7805 is already ordered.
Replacing the PIC18F87K90 is necessary but that makes no sense without having the HEX dump of the new controler.
Does anybody have such a power supply and could do a HEX dump of the Flash and EEPROM memory?

by re-atariHello all, as the title says, I'm very much in need of a valid firmware dump of a Anycubic Photon 5.5 3D resin printer. It's stored in a Winbond 25Q32, so it's 4Mbyte.
Here's a little background for my request. A few weeks ago I bought this 3D printer from a guy who had moved on to a PLA printer. I got it at a vey reasonable price, as it was in a defective state. The seller told me that he had experienced a power failure during a firmware upgrade, after which the printer appeared to be dead. He thought the firmware was corrupted in such a way that the printer was now bricked. As he... -
by Buzzfuzz2kHi Everyone,
I'm facing a problem with a locked bios with a password and i can't find how to remove it...
The small computer is only booting on a M2 ssd Windows partition and i get a "signed partition error" if i try to boot on the same SSD with another Os (linux for example).
