This thread is for repairing IMEI on U600 and U600B phones, with damaged NVM area, using last NsPro version.

Read flash with last NsPro version from damaged phone (U600 or U600B)
Will result an 192Kb file.

For repair IMEI you must post:
1. File readed with NsPro from damaged phone
2. S/N from the phone label (under the battery)

I will answer to your post with a file that will fix your phone.
Each phone need a different file.

To repair the phone, flash that file into phone using NsPro.

Make sure that Repair Mode and Differences only are UNCHECKED when writing NVM file on phone.

After phone was repaired, can be flashed with any firmware.
The IMEI wont be damaged on flashing.
Just make sure that you use NsPro to flash the phone.
