I haven't run any custom ROMs on the M so I am not certain what the problems might be with 4.4 versions, but I can talk to dhacker and see if he is aware of any specific issues and/or fixes for GSM service. This hack unlocks the radio itself and has nothing to do with the ROM, but the ROM has to support the radio properly for services to function, obviously. The apns_config.xml is a typical problem that needs editing but there are other RIL libs and binaries that need to be there as well as build.prop configurations that also need to be set for everything to work.
None of that can work at all until the radio is unlocked in the NVM first though.
Long time troller/first time poster and thank you to many of the developers on this site for many things I have used and especially cellzealot for the NV hack for the RAZR M to use ATT. I saw this thread was still relatively active so I thought I would post here.
I was able to successfully use radiocomm and I can get att service with an h+ symbol. But reception is horrible and frequently drops service completely. Is there a tutorial somewhere regarding apns_config.xml changes/ RIL libs/binaries/build.prop configurations? I like using my unlimited ATT data plan for cheap! also if someone would like to take this opportunity to inform me how I can be of service to this community- I'm no hacker, but have successfully performed many mods described on this forum- I would gladly contribute.
I am on xt907, android version 4.1.2, system version 98.18.78.xt907.verizon.en.us, kernel version 3.0.31, build number 9.8.1q-78
Only mod is unlocked the radio in NVM.
Fixed!- I input *#*#4636#*#* into the dialer and chose GSM auto and this seemed to help. I had previously tried to change this in the mobile network settings (because i didn't know about *#*#4636#*#*) but that was not as effective.
