Ideapad 700-15ISK Type 80RU MDM - INVALID

[internetdivisor]

Dear Gents

I rescued a Lenovo Ideapad 700-15ISK Type 80RU.
The matter is that Bios is displaying:

Product Name - Lenovo E5 - Wrong, it should be the above name
MTM - INVALID - should be replaced by the number on the sticker on the backside of the laptop
Lenovo SN - INVALID - should be replaced by the number on the sticker on the backside of the laptop
UUID Number - 0000000-000 etc, this one might have been lost because i don't have it anywhere.
All te info can be seen in the attachement.

Now, can someone please add the Name, MTM and SN to the bios file so they will be updated as they should. Any help or indication would be greatly apreciated.

The OEM update file of the laptop is available at: https://download.lenovo.com/consumer/mob...cn63ww.exe
If you think that other stuff needs unlocking, etc. please feel free to modify as you desire, as I don't have any other requests.

Also after searching the web I fear that the bios or EC may have been corruputed or badly flashed, not moded tho.

Thank you in advance for the help and support

Dear fire1234,

This is the bios that is actually runing as we speak. If you need any other info please direct me to how to provide it.
PS: everything works well with the exception of the integrated tx950M that gives a 43 error code in Windows, might be BIOS might not, that will be investigated later on.

Best Regards and thank you in advance for helping.

I also attached the RW-Everything report. This is as far as I know to extract information from the actual bios.

you need to make a bios copy with the programmer and then you can add sections where SN, MTM and Name are given

Dear fire, thanks for the info but unfortunately I am a home-user and and I don't have any hardware tools.

Can this be accomplished by editing the files that i attached here by someone who knows what he is doing?

Sadly so far I wasn't able to find some software, program etc to make a dump or backup of the actual BIOS that is running (i mean the actual settings) given that the File Type: zip E5CN63WW.zip (3.33 MB, 2 views) is updated at this time and runs the laptop.

LE: I also have an identical board, bricked that is, that has the correct BIOS written with the correct details. Are they ok for swap? - If available this should be the last resort if all else fails.

Thanks for any info or help

There is actually a tool which can be used to set these values.

But since I dont have it at home and I dont remember the name of it (something with lvar...), I cant post it right now.

As I found, for the Motherboard SKL MB 15221-1, the one in discussion, this is the BIN dump.

LVAR64, LVAR32, LvarDos, etc does not work on Phoenix BIOS as I found so far, when trying to set the values, either in DOS or Windows it throws an error about SPI interface not ready or something.
As I also found out, and got the full "Lenovo Internal Document", it was used for Y700-15ISK and not IDEAPAD 700-15ISK. Offtopic: can't understand why Lenovo launched 2 products with almost identical names, but that's just me.

You might be right but last time I think I used it on ideapad 500-14ISK and it worked.

So maybe theres another issue?
I have used it both inside windows and using windows installer. I think running it in admin mode was necessary. And /w /ln /c "blablabla" was the command format.

Far from me to argue your opinion, when you have the time please send me your version in order to try it. The one I had gave that Error even when I tried to read the info EX: LvarWin64V221.exe /r /ln or something like that, popped the SPI interface Not Ready . And I never seen that error on the web

Re: Ideapad 700-15ISK Type 80RU MDM - INVALID

So it looks like we are getting closer. Suggested by another member I tried the Winflash64 that comes in the BIOS update package with the following command string, besides other:

Winflash64.exe /patch /dms "LENOVO" /nodelay /exit

And I get this:

Phoenix SCT Flash for Windows V2.35.0.0

SecureFlash BIOS detected.
Initialize Flash module.
Read current BIOS

Begin Flashing......
----++++++------+++++++ etc.
Image flashing done.

Flashing finished.

WARNING: BCP DMI run time update service failed =0x8000045C

BIOS is updated successfully.

Re: Ideapad 700-15ISK Type 80RU MDM - INVALID

At this point I believe that the commands should be put in the winflash64.bat using almost the same method used to flash the new OEM BIOS with restart, UEFI write and restart but I am stuck at this points given that the commands in there elude me .

Please adivise

Re: Ideapad 700-15ISK Type 80RU MDM - INVALID

The bios you posted at #3 is a .CAP file not a full bios backup,its a bios update extracted from the lenovo bios update exe.The bios at post #8 is corrupt. Try this bios at post #8 https://www.badcaps.net/forum/showthread.php?p=890606 .

The DMI info is DMI 801000 - 8011FF Length 200 ,the win key NWYDW-8JW** ,if the bios is updated to the latest version the win key is in a slightly different place .No need to use lvar or any other DMI tools,just a hex editor.

Re: Ideapad 700-15ISK Type 80RU MDM - INVALID

Thanks for the info, now, I am a real newbie when it comes to BIOS and manual flashing. I got the bin you posted at #8, the BIN. Now, how to flash it without bricking something?

I have no idea how to flash the EC or the Bin you posted.
LE: I have no idea how to backup the actual BIOS that is running on the machine in order to post it here for checking. If that can help, please be so kind as to direct me to how it should be done.
If it's too much to ask, thanks for all the help you provided so far and best regards.

Re: Ideapad 700-15ISK Type 80RU MDM - INVALID

Should I use Plhash in a bootable DOS USB for both files with the command : phlash "filename".bin for both the files you provided?

Thanks

Re: Ideapad 700-15ISK Type 80RU MDM - INVALID

The most reliable way is to use an SPI bios programmer,such as a chepo CH341A + clip + optional 1.8V adapter. You can try from windows or dos but you could brick it. Rename the bios to clean.bin ,and edit winflash64.bat to this:

WinFlash64 /file clean.bin /bak /all /cvar /bbl /bcp /sd /sn /silent /cac /cbp 30 /shutdown

Re: Ideapad 700-15ISK Type 80RU MDM - INVALID

Ok, getting to it. Should I also do the same procedure with EC? I won't edit anything just rename the file.

I'll keep you posted.

PS: the actual bios is the file attached on the EXE mentioned above.

Re: Ideapad 700-15ISK Type 80RU MDM - INVALID

Ok, nothing happens. If I run the command from DOS it says /all command is invalid and if I delete the coomand and run the update it says:
ERROR 233 - Only secured capsule is allowed on a SecureFlash system!

Re: Ideapad 700-15ISK Type 80RU MDM - INVALID

Ah yes i forgot. You can flash the CAP file to update the bios but not the .bin .You`ll have to use an SPI programmer to flash the .bin
