    One more theory to confirm tomorrow - flash EC one more time, and start it from scratch... maybe initialize eeprom works incorrectly from the second time....

      Re: mec 16xx dump with info block

      When adding products name with utiliti, do not use Thinkpad, just type p14s Gen1, utility adds Thinkpad by itself and if you also type Thinkpad, then the name will be Thinkpad Thinkpad p14s gen1, and thats why you get error.

      My laptop is P14s gen1. EC Flashed with rt809f, no problem, same resistor for jtag reset and the same jtag pinout as showed earlier in the topic. Now we need to write serials back, and here is the problem!
      Googling this problem lead me to this video https://www.youtube.com/watch?v=U30H3_iNM3k
      I am using ThinkPad maintenance utilities 1.11(x64) blabla august.12.2020. First time I didnt have planar service option in the forst menu at all. Ok, I found two files - plnsrv.ini and tpconfig.ini with the utility. but plnsrv.ini doesnt have P14s entry for the model! Ok, notepad and lets add this entry manually. Copied two files on the flash drive in the same folder with boot64.efi and planar service option appeared. But anyway - i am introducing all info - c0, model, kb language, uuid, and after restart - the same 2202 Product name...

      Now I am thinking that this utility is too outdated for the p14s... And it looks to me that I am out of options... Maybe somebody have any thoughts? Will be very gratefull....

        THANKS MAN you are right, Lenovo wants exact model to be written, so I added 20S5=ThinkPad P14s Gen 1 in the plnsrv and all went fine! Thanks for the help guys!

I believe that few here know how to do it and no one shares it, I understand that certain types of information are not shared and are sold! But I persisted, and I come to inform you that the (Thinkpad T14 1st 20S1) was unlocked by an RT809H the only programmer I have, as I don't have access to a vertyanov. Here are the photos in the attachment, now I just need to invert the bios information, but I had taken a photo before.

                Hello everyone - I am new to the Forum and Bios Flashing/Unlocking - I have a Lenovo T14 Gen1 and have been reading through these threads - some of it makes sense but some does not as I am new to this. I have a CH341a and have used it with a few HP laptops with success using RCUnlocker tool.

                Please could someone explain briefly whether it is realistic for me to unlock the T14 as it seems like a complicated process requiring special tools. If the RT809H does it, I could buy this? Will I have to do some soldering?

                Thank you in advance.

                  Nah, you need to buy another programmer. Ch341 is only for SPI, not for jtag.

                    Thank you for replying - if I purchased a RT809H is this a very hard job to unlock the password - I am contemplating paying someone to do this but would like to do it myself if I can learn.

                        U can also try Rt809f or vertiyano or svod
                        Among all cheapest is “F”

                            hey, guys. a small question about service information. i was able to reflash eeprom area, but now i need input some data to eeprom area via UEFITool. for instance, i can't type correct "Machine Type and Serial number". also, "Product name is invalid", that's what startup sequence telling me every time i boot. if someone can explaine this issue, it would be nice.

                              lenovo doesn't give support for lost password
                              but give support for dead or not working laptop within warranty
