Ok friend,
there is a tool = Prr.exe (Svl7) that bypass this error !!!
Can You upload a Screen Shot of that phase when flashing is locked as You ave to press enter to continue (is wrote n screen) ?
I would see if It's possible to flash like many Others users have done !
Let me know
Regards

Hi ,
thanks for your quick repsonse.
I've difficulties to understand, what you are saying.
What should I do first? The tool Prr.exe or the screenshot from the error message of the first try?
How can I do a screenshot in DOS-Mode?

Michael

Use a camera or phone to make shots of that sequence to look what is happen !
Upload pics here and I will try to understand.

Hi friend,
into m Bios Mod is Always used prr.exe and looking your picture You'll see that the first coman executing is prr.exe and then FPT.exe.
So You have the issue as prr.exe cannot bypass the error !!!
I am sorry You have to use an SPI Exteral USB Programmer.

I found this if this could be to any help http://www.thinkwiki.org/wiki/Problem_wi...twork_card
As i also to find out there is 4 different versions wifi cards for Laptops, there is IBM, HP, DELL and one that called NORMAL.
If you put in a not supported WIFI mini card you get this "Unauthorized network card is plugged in - Power off and remove the miniPCI network card"

Hi friend,
the only solution is to use an SPI External USB Programmer to write directly into your Eeprom the Bios Mod !!!

Look here :

OKi thanks, but i found out know wath to do, as i said there is 4 models of this PCI-e card wifi IBM, HP, DELL, NORMAL, the NORMAL is wath you can buy in stores and should work in most computers. If you want one for a lenovo you buy a IBM it should be marked as a IBM compatible, thats wath i found out on Alibaba from sales. I also send a email to Intel how distinguish the different compatible WiFi cards, if you can do it on any number of the manufacturing or so.

Hello there!

I would also like to ask you for help removing the whitelist limitation on my Lenovo Z50-70. My current wireless card is qualcomm atheros ar956x and I'm trying to upgrade it to Intel Dual Band Wireless 7260ac, yet I encountered the same error (unauthorized wireless card...) as others.

Here is the backup of my current bios: http://ulozto.net/xpUsmzDi/lenovo-9bcn25ww-rom .

Thank you very much for your help!
