Help with Thinkpad Maintenace Utility on T590

[Maxpower3]

hmmm why u not answer me ? i see you are online everyday

My version is not finished at the moment
I don't have time to take care of it and it is not available .


Write access is locked, if your usb key is well done with the utility provided,
you must have the rights.

No access, weird.
Rest of password, or Ec corrupted may be ?
try to load the default setup, clean the security tab etc. and try again.

For block 84, I have no idea what it corresponds to

I don't know what you originally did to the PC, it's hard to help you anymore


try this one ThinkPad Maintenance Utilities V1.19(X64)

Sorry i didn't see your post.

But i found solution now!!!
Problem ist SVOD4. In some cases the svod4 programmer makes the mec chip (some kind of) locked. If this happenes the notebook is running, but mec isn't writable.
Then you need RT809H, write the dump back with this programmer and the problem ist gone, now i can write all data like B0 etc with U1. No Problems anymore and no error messages.
The funny part is: once programming with RT809H, programming with svod4 is possible again.

can you post your EC dumps?
have you tried planar services?
with dump eeprom (5), are there serials and information marked in it ?

you can try with SERUPDT (exemple 7 and 8 in my pics)

with lenovo diskette
create eeprom.dat with serial info
place in root of usbkey
IN EFI SHELL
cd A:\MTMSN\ThinkPad\

for write
SERUPDT L eeprom.dat

for save in eeprom.dat
SERUPDT S eeprom.dat

Hello, can you share your software???
