I received a Lenovo Z6 Pro phone on monday with "global rom" which had QCN file messed up. not only that, it has Wlan and modem messed up too. All that could be fixed by using ZUI.com/iunlock website's provided unlock .img file, but for that i need to provide the site with imei and serial numbers.
Problem is - until my phone connects to cellular network and it's imei is registered as active, that site will not acknowledge my imei1.
To do that, first I need a working qcn file. I can rebuild the qcn file with MY imei's but I need a genuine z6 pro qcn and I can't seem to find any to download anywhere
so, please... if any1 knows where to get it or has theirs backed up - would really help a lot!

I am in serious need of a hex or bin with the qnc file. Does anyone have a QCN file they would be willing to send?
I was working on my Phone with qpst attempting to get internet. When i finally got internet to work correctly i lost the ability to send sms messages. So i went back in to fix it again but must have screwed up bad. Now i have only phone. I can receive sms but cannot recive. And #777 no longer gets me data.
Or if anyone would be willing to look at my qcn and tell me what i did wrong?
Here is the problom qcn. If anyone can tell me what is wrong?
Hi,
seems like I've just noticed this issue, even if my last flashing (no, I didn't use that Odin option to clear efs) has been done 7 months ago.
The (italian) guide I have read when I bought the Spica back in June didn't mention ANYTHING regarding backing up the efs folder.
My IMEI is 00000000000000, but I can succesfully make and receive calls, sms, and use HSDPA data (Postemobile, a virtual operator working on Vodafone network).
My efs folder contains only a nv_data file.
My doubts are:
-If my IMEI is blank, why I haven't any problem at all?
-If I flash with ODIN a stock 2.1 firmware, can I recover the issue?
-I asked a friend a good nv_data file from an eastern Europe Spica, in an extreme case may I overwrite my nv_data file?
-Any hints regarding the policy of the US carriers if the IMEI is blank? It would be a problem if I couldn't connect to the mobile network. Last time ATT and T-Mobile worked well, but that was before the last ROM flashing, so I don't know...
thanks
Your nv_data file did get corrupted or deleted. This could happen if you ticked the option "Debug Only" -> "Phone EFS Clear" option in Odin.
When the file is broken or missing a new file is created at startup which does not contain IMEI data. Look if you have a nv_data.bak file in your efs folder. You can rename it and look if it fixes the fault. If there is no such file then you have a problem. This can't be fixed easily.
You can go to a professional unlock shop nearby and get a emei repair.
Ore you can contact this guy and get a fix for 20$:

PS: The missing imei will not cause problems with the phone. The complete phone will work without a problem.
Hi since this is technical, and Google has no answers for me at least I can't find any. I need urgent help on to repairing my imei on a qcn file, I can only use that since I will lose my AWS bands with Wind Mobile. I want to use the imei that is back of the battery and is same as my box that I have. I have 04 Imei right now. I don't know how to edit the qcn file with any hex editor, it's all bunch of algorithms of numbers and letters.
