Re: IdeaPad 720s-13ARR: if the bios won't be updated anymore?

Hi,

I can confirm that flashing the BIOS via HW works fine. Also the official display driver from the Lenovo page now work without any problems.

 

Only thing still open now is to reenter correct P/N and Serial Number. My system keeps freezing when I try to read or write any information using lv** oder lv**32 in Windows 10. The missing P/N and S/N do not seem to generate any problems, still beeing able to reenter all the information would be great. Any hints how to do that correctly or which tool to use?

Thanks

MSI

The program whose name may not be named get stuck in my environment. W10 instantly freezes and i have to reset.

The chinese blog version can not be downloaded. Maybe the "great wall" does not like me. :-D

When sombody has the tool, i really like to test that. Send me a PM.

Thank you Axus, download worked. Change log indicates AMD compatibility, so the correct version of the tool seems to matter.

Will try that later an will give short feedback afterwards.

Hi!
Thanks for the files! I have downloaded them, but won't use them yet: I have asked about the Bios-issue in the German section of this forum and the admin there, Juraj, will ask someone at Lenovo. This person already helped me with a few other questions and fortunately contacted Lenovo directly with an earlier issue.

Both admins / mods there, Juraj and Grisu, are very helpful and dedicated to their job in the forums.
At once there is / if there is any reply I will post it here.

Re: IdeaPad 720s-13ARR: if the bios won't be updated anymore?

It generally worked, MTM, S/N and Product are back in the Bios. Thank you all for the support :-)

 

Still open: I'm not sure how to write the preconfigured Windows Licence back to the BIOS, but I'm not sure if this is really needed. Maybe only if I need to do a complete reinstall of the OS someday. If anybody has instructions how to do that part correctly that would be great, this would really finalize the whole BIOS update procedure.

Re: IdeaPad 720s-13ARR: if the bios won't be updated anymore?

I found official doc for magic tool on lenovo site.

 

 

I think i found a way to restore it.

1. use product key viewer program to view your own key

2. create binary file 49 bytes replace 00000-00000-00000-00000-00000 with your product key.

01 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 1D 00 00 00 30 30 30 30 30 2D 30 30 30 30 30 2D 30 30 30 30 30 2D 30 30 30 30 30 2D 30 30 30 30 30

3. use magic tool again to update msdm

 

I've update my blog with test key (all zero) and windows know it. let's try.

Re: IdeaPad 720s-13ARR: if the bios won't be updated anymore?

After checking old information I have collected before updating bios.

I found offset changed in protected and private region.

I think we can just change platform.ini to enable region movement.

EnablePrivateRegionMovement=0 -> 1
EnableProtectionRegionMovement=0 -> 1

 

If anyone who like to use hardware programmer please try that first.

maybe we don't needed a complicate tools.
