I'm having a problem with my RAZR xt910 651.167.21.xt910.retail.en.EU GB 2.3.6 (rooted) , I bought it a month ago and it was working very good, there was nothing wrong with it. But some days ago it turned off by itself (having 80% battery) and I couldn't turn it on. So I plugged in the battery charger (AC) and it showed me that I got 5% battery :s. But when I turned it on, it showed me 76% battery and my SIM card wasn't recognized (But everything else worked fine). Then I went to the Settings menu > About phone and it shows the Baseband unknown and in "Status" it shows Network unknown, Mobile network type Unknown, IMEI Unknown and IMEI SV Unknown.
I flashed it several times with different fastboot files from this site but it didn't help. I attached a picture of the Status menu.
Please help me! I found no solution to this problem : / I will be very thankful!!!
PS: the Wi-Fi stopped working, it just tries to connect, but it doesn't.
