OK first post here other then intro and I got major issue with an XT907 retail on VZW.
Problem: Lost 4G data/modem connection, still have phone use for calls and WiFi.
How: got a replacement phone after screen broke on insurance, new phone came with 98.18.78. I then remember that there was a fix to roll back a the software to gain root then update. All was working at this point.
Like a moron being to quick to jump, flashed VZW_XT907_4.1.2-9.8.1Q-66_1FF to the phone and of course it failed at the trusted zone. Then flashed the current VRZ_XT907_9.8.1Q-78-1_1FF to the phone to put things back where they were.
(both flash files are from "Droid-Developers SBF" and passed the MD5 checks)
BBut after boot up the phone could no longer conect to the network but would connect over WiFi.
Tried:
Using the Samuri fix for rooting the phone and reappling update - No go
Matts razr M utility 1.2 both option 1 and 2 - No go
I flashed stock 98.15.66 with out the Trusted Zone (edited the .xml file)- No go
Tried using files from another working Razr M in the house on older firmware and still No go
In each case I also allowed the phone to update using the system update option over WiFi and every thing would look good but the 4G data has not come back. Checked APNs as well names are different but settings are the same and I dont think its the name since my Droid 4 does use those names and both the working M and the D4 have the same settings.
At a loss here and need some help BAD.
I know that this has to have happened to some one else since all I did was flash an older software (bad idea) to the phone and then flash current or allow it to update again and still no data connection.
Any help please.
Thanks
