P50 - updating MTM/SN/UUID
P50 - updating MTM/SN/UUID
TL;DR: Hi, I need help in finding a way to update MTM/SN/UUID on new P50 MB. The BIOS update utility from support pages doesn't work for me.
Greetings,
I bought a new motherboard for my broken P50. Installed it a week ago and everything is perfect, but the INVALID Machine Type Model, Serial Number, UUID. As I understood from numerous posts here and there I need to prepare a bootable disk (USB) with the utility from Lenovo and this should give me the option to update those fields. However, after downloading "BIOS Update Utility (Windows)" (from here: https://pcsupport.lenovo.com/gb/en/prod ... IOS%2FUEFI, which is P50 support product page) I couldn't create a bootable disk with it. Despite the documentation clearly states that running mkusbkey.bat file will make USB drive bootable, it doesn't. It just copies some files to the drive. I tried also first make a FreeDOS bootable with Rufus and then run that mkusbkey.bat batch file to copy necessary files, however, after booting from it - there is nothing to do: not a single EXE file (except for the LOCALE directory which holds drivers for screen and keyboard, probably coming from FreeDOS).
I searched the web, and couldn't find a solution. Some people say that they were able to get somewhere a specialized BIOS tool that can update those fields and this SW is given to the service centers, not intended for end-user usage. If somebody has this, please share it. So far all solutions I could find didn't work for me, unfortunately.
Will really appreciate any help!
Thanks!
PS. Not sure what is needed, here are some of the details:
MT-M: 20EN-0013US
OS: Win10
BIOS: wmic bios get name: N1EET57W (v1.30 )
PPS. BTW, since I have upgraded (a bit) my MB, should the MTM change as well? FRU 01AY360 (6700,2G,WIN,N-AMT,Y-TPM,N-RA) --> FRU 01AY364 (6820,4G,WIN,Y-AMT,Y-TPM,N-RA)

Don't know if this still works: http://download.lenovo.com/ibmdl/pub/pc ... tm38us.exe

Re: P50 - updating MTM/SN/UUID
OK, I have updated the UUID. 1 problem less..
Regarding the S/N I have read in HMM of P50 about using the SN update utility. The problem is that my data:
Machine Type: 20EN
Model Number: 0013
Country: US
S/N: ######## (8 letters)
is incompatible with the format of the utility.
According to numerous sources online (blogs, forum posts) I need to enter 20-letter string containing:
1STTTTMMMMCCSSSSSSSS
Where:
1S - constant prefix (not sure if this is correct prefix for P50 though)
TTTT - Machine Type
MMMM - Model Number
CC - country
SSSSSSSS - Serial number as appears on the sticker.
This perfectly aligns with my data, however the utility asks for 16-letter string in the form:
1STTTTMMMSSSSSSS
where MMM is a 3-letter Model Number and SSSSSSS is a 7-letter Serial number.
Looks like this utility is incompatible with P50??

Re: P50 - updating MTM/SN/UUID
Try using P50 and the serial number. That is, after all the model number.

From the documentation here:
https://nanopdf.com/download/20-incos_pdf
It seems you should be able to select between 7-digit model and 10-digit model systems when entering device type.

Re: P50 - updating MTM/SN/UUID
There is also an EFI version: https://download.lenovo.com/pccbbs/mobiles/n1ctm02w.zip
It contains only 1 file: BootX64.efi but I don't know how to run such a utility.
Latest: https://download.lenovo.com/pccbbs/mobiles/n1ctm07w.zip
with more info.

Re: P50 - updating MTM/SN/UUID
This was it. I couldn't find any manual for this utility. I had to choose C0 option for the longer SN.dr_st wrote: ↑Tue Jul 28, 2020 7:42 amFrom the documentation here:
