I recently got the Verizon Droid Razr M XT907 and used it to go from Cricket CDMA to GSM. It's running 4.4.2 build KDA20.62-15.1(most recent update), no root and locked bootloader. The phone is working fine except for random reboots about every one to two hours except when on WiFi. I'm using the AIO APN's and have tried AT&T APN's for preferred network type I have tried Global and GSM/UMTS with network options GSM only, UMTS only and automatic. Under Global and GSM/UMTS (UMTS only and automatic) I get H+ for data along with random reboots. I'm currently on GSM/UMTS GSM only I get G and E for data with no reboots as of yet.
I've checked with the previous owner and this is the first time it has done this. I have tried everything I have searched for from factory reset, enabling all factory apps to removing apps I installed. I didn't have any of the type of apps mentioned in my searches that may cause this problem.
I don't know if this is an issue with the phone, with it being a Verizon phone or with the sim from Cricket.
Any help will be greatly appreciated,
Thank You
Probably software but it could be the battery or other hardware failure

So have you tried a factory reset?

Yes I have several times. After googling an app call modem fast dormancy monitor service to see what it was I came across a Motorola forum that discussed it and they had the same problems. The app only effects the phone when not using Verizon for service along with KitKat. The only way I've found to disable it is with root access and with the latest update it's not possible that I know of.

Hi all,
i got a problem with my phone...
for some reason it stopped getting signal a few days ago..
when i try searching for a network i get an error saying "Error while searching for networks"...
now, i've already searched the forum and found a few solutions but for some reason nothing helps!
tryed switching my sim with another friend's sim - nothing
reflashed 4.3 - nothing
reflashed the latest radios - nothing
reflashed all the radios from the 4.2.2 versions to the 4.3 versions - nothing
reflashed stock 4.2.2 including radios, kernel and everything - still nothing...
i got no idea what else to do /=
anyone can help?
thanks!
anyone?
maybe hardware failure?
what recovery you use? TWRP or CWM?
this also happen to me and not only to N4 but also to my Gnex, but after restart i've got signal again

im hoping its not hardware related...
quick update - i can get a connection but only when i "set prefered network type" to gsm only (through the *#*#4636#*#* menu)
still cant get HSPA or HSPA+ and after reboot i need to set it to gsm all over again
Sounds Like antennae problems then. High probability of hardware fault

the phone is only two weeks old /=
is there a way to check if its really the antenna?
Check ur APN.. Usually its the #1 culprit...
Nexus 4 - PA rom and franco kernel
checked the APN... it's correct /=
Apn well not have any effect on general signal. Only connecting to data /mms
The fact that you could connect before hand and now can't means something has changed.
Because you can still connect to gsm seems that the radio software is good.
You have flashed Different roms and radios eliminating software as the culprit
By process of elimination I would say you have a hardware fault. Either in the radio chip or an antenna.

I recently flashed NAE modem from this thread http://forum.xda-developers.com/showthread.php?t=2338919&highlight=signal And now I have literally no signal. The only APN listed now is LTE - SPRINT OTA otasn and it is grayed out so I can not add a new one. Does anyone have or know of any fixes for this? I tried flashing back to MJA modem but all of them on that thread only have this one APN and they are all grayed out. I have been searching all over and can't really find a good fix for this so any help would be GREATLY appreciated. My GS4 is rooted and have Philz and Negalite WondeROM if that helps at all. I assume it is an APN issue since I do not have the one I see most people talking about...however I can not add new ones since it is gray....i suck lol. Thanks again for any help at all.
I'm on stock unrooted NAE and have them greyed out so that means that's "normal"

Play around with the mobile network settings... and do profile and prl updates... see how that goes

my carrier supports wifi calling but only if you buy the phone directly from them which means it needs to run their old version of android. Is there any way around this? Not too keen on going back a release or two and getting their bloatware on my phone

If your device is rooted you can download CSC feature expert or CSC Master from the play store. The option is in there somewhere. There's loads of other stuff you can enable too. Your phone can do lots they don't allow by default!

thanks, my phone is not rooted. Is there no way to do this without rooting?
i have read all the posts about that, but nothing helped
tried to flash Chroma and select a different band, but this doesn't help

Yeah that's a setting you don't want to touch. I remember a thread here about how to fix this in this forum so a search will probably find it for you. I think people had to re flash the radio. Or flashing pure nexus. I don't remember now it was a while ago.

Fixed, thanks!
My cellular data keeps on disconnecting and it shows a exclamation point on the signal. I'm using G900v on t-mobile network. The issue only happens running Marshmallow. I've tried AICP, PhoenixRom and Cyanogenmod 13. All have the same issue. It happens randomly and immediately after a phone call. I constantly have to turn on and off data to reset it.
If I install Lollipop there are no issues. I've tried everything I can find online but nothing seems to work. My APN setting are correct.
Can anyone help figure out why?
Make sure you are on a mm modem check by going to settings about and check what baseband /modem you are on

Yes its GSM. I've tried changing the network type and also installed Advanced Signal Status to change it. Both options didn't solve the issue.

Best bet is to reinstall a lolipop firmware in odin and reroot and reboot bootloader unlock then reinstall mm rom

Make sure to backup /transfer all important data to a pc before you flash lolipop firmware

Tried that already. Went back to stock Verizon Lollipop.... Rooted.... bootloader unlock and updated to MM.
Let me know if you find a solution to this! Been bothering me for a while. To be clear, my problem only exists in non-TouchWiz ROMS.
I am also having exactly same issue but instead of exclamation sign, I get small white x on the signal bars. I also have Verizon S5 that I am using on T-mobile. I had no issues when I was using ATT but this problem started as soon as I switched to T-mobile. My data disconnects randomly and I have to either disable or switch to airplane mode to enable data. Is there a solution to this problem without going back to Lollipop? Currently, I am on Cosmin-OS 7.1.1
does anyone know where i can find the latest modem to flash on my verizon variant , my signal has been poor lately and i wanted to know if flashing the latest baseband would help currently im on a 7.1.2 rom and the baseband is the g900vvvru2bpb1 .
