I have same issue. My sim card is not recognized in firefox os .So i tried to restore my Stock Os. SAME PROBLEM.Tried several Rom 

 

Please help!

 

@Bhanne Did you solve it?

[Guest xbadaxex]

OMG IMEI unknown,IMEI SV unknown :angry:

SOLVED! My Sim card is now recognized

@Bhanne  Do the following steps.

 

1.Do full Wipe.

2.Restore Stock Rom from your Backup

3.Go to Settings>About phone and write down the buildnumber

4.Search  the stock firmware with your build number in google or huawei official website,modaco,htcmania.

5.After download completed.unzip the firmware copy dload folder to your external SDCARD (path should be like this "sdcard\dload\UPDATE.APP"

6.Go to Settings>System update>local update and flash it.

 

After installing i got boot loop twice.then it boots normally:)

Now your device will return to stock Rom with stock recovery and locked bootloader.
