I have been hunting around, trying to find a solution
I am having XT-912 Verizon Droid Razr Maxx model, and i am in India using a GSM network.
All cdma roms, dont show gsm signal bars, hence i am using patch to enable gsm using coupe of build.prop entries. [Src: http://www.internauta37.altervista.org/how-and-patch-fully-enable-gsm-verizon-cdma-phones-android]
Everything works well, but the main problem is whenever i move from one area to another, many times phone loses signal and doesnt re-connect for a loooong time.
It gets very irritating as i have been missing calls, msgs, etc
1. The problem wasnt there initially and i feel some junk data or cache in baseband might be causing it?
2. I think the problem might be a ril or baseband mismatch. I am on cdma_n_05.21.00R which is latest baseband, any idea if trying different basebands might help solve this proble,?
3. Also is it possible to flash older baseband [ics or gb or older jb] on my phone to check compatibility or will i cause brick or locking etc?
Also i read about CID, and its something about region secific identifier, so anything about that affecting my device?

ok this phone a brand new, i can receive calls and text but when i dial a number and try to make a call the phone restarts
This is factory unlocked and not rooted
Try flashing a newer radio rom.
I dont want to root it incase i cant get the original rom back.
It is weird as, i have tried with every sim card to make calls and it works but when i put the 3 sim in does plays up
We experienced the same issue on some Turkish networks as well and flashing a newer radio rom fixed the problem. Flashing roms and rooting are totally different. What you need is a newer version of your current baseband ( radio rom ) sbf and official motorola software flasher " RSD Lite 5.3 "
Hope it helps.
Thank you so much for that Semseddin.
My problem solved, i just flashed it using RSD lite 4.9
Thanks everyone
Hi. I've been having the exact same issue. I've got an unlocked AT&T Atrix and I'm trying to use a Three UK sim (I'm in the UK). I'm a bit new to the world of android, can someone post a link to an appropriate Radio Rom?
Thanks for any help!!
OK after a little more web searching I've found a (sort of) solution -
"Here's a quick fix for it thou, (not permanent)....
1. type *#*#4636#*#* on the dialer
2. Chose Phone Information
3. Set preferred network to GSM only
Viola...its fixed
problem with this fix is that you wont be able to use your 3G network but the dialer should be working."
Problem is of course that you can't use your 3G connection. Hope this helps anyone else with the same issue.

Why is it always 3 that cause a problem?
When the Nokia N900 came out, that wouldn't work with 3 initially until a couple of updates later!

May not work for Pay as you go? I didn't think that it had 2G fall back?
I just flashed simply honey 5.1 and now i cant recieve calls or even get a data signal. help? i seem to be having the same problem with anything simply honey 3.8+
Back to stock (Odin), and than try reflashing. Looks like bad flash. Unless you had bad luck like me and core files got messed up...
I have Odin'd back and reflashed twice now
My stock works fine, but whenever I flash I lose my data capabilities and I can't receive calls. Is that what it's like when your core files get messed up? If so, how to fix?
No, you have different problem than me than.... my does not connect at all in any rom.
sorry but your problem is beyond my knowledge, I would say that maybe bad download, but it seams you downloaded more that one rom so... sorry
Go to settings, network, mobile, check data, check roaming, then go to network operator, choose provider automatically.
After it finishes, go back and go to access point names and make sure you have the correct apn.
If not, please state the rom, kernel, and modem by going to settings, about.
After I checked Data and roaming and set it to choose automatically it said "registered on network" but when I went to APN it says no items.
I am using:
Firmware
2.3.4
Baseband
T959UVKB5
Kernel
2.6.35.7-I9000XXJVP-CL264642
Bullet-JVP-1.2Ghz-v5.4-voodoo#12
Build number
GINGERBREAD.XXJVR
Go to the Market, search for APN Global, install it and let it install your settings for your carrier. Let me know if you still need help.
Also, what is your carrier and which country? You have an I9000 kernel that's why I'm asking.
Hey, I noticed you folks were mentioning something like what I was having trouble with. My phone shows that I have a 3G or H connection; however, any app that uses data fails to connect. Any ideas on solving this? It seems as though Tomulek may have experience with my issue.
Hello.
Here is my problem.
In fact, my gsm Internet connection used to work fine but recently, in the last updates, i have data situations. My Internet connection is blocked even whith the HSDPA icon.
I tried to fix this problem by:
-Doing wipes (factory, cache) reset
-Installing different recent roms
-Installing different kernel
My problem is not from my ICS upgrade. It came largely after.
Do you have any ideas how to fix this problem?
All of them are welcome.
My actual rom is Litening 2.7 rom under the 3.0.15-9100XXLPS-CL294511 CWM kernel.
My baseband is 9100XXLPS
I'm under android 4.0.3 ICS
I'm rooted.
Thanks for your help.
Edit:
I kept a backup of an older rom. When i restore it, the Internet GSM Works again. But the problem stay with the most recent roms. I want to keep beeing updated.
I'm in france under the operator Orange.
Correct IMEI ???
jje
Yes. I compared between the state in "About the phone" and under the battery. It's the same code.
No ideas at all??
Sounds like incorrect APN settings to me.
Maybe. Because sometimes when i try to search Network Operators, the phone keep searching until i use the touch "go back". But i have no idea how to fix.
Detail: My phone number is displayed as unknown. Everything works: Call, sms, i have the icon E,3G,H. But when i use the Internet navigator, i have the Orange(Operator) website which tell me that my phone is not compatible with the Internet connection. Sometimes, i have another website which suggest me to pay for an Internet connection. But i already pay an Internet connection. (Vultures)
Edit: Never Mind. Problem solved.
Guys I need urgent help. I have flashed 38p radio on my Atrix and now it is reporting unknown baseband and IMEI. Cell service and data doesn't work anymore. I have tried flashing other radios, and even the old one that was working is not working anymore. I always get an unknown baseband error. Is there any way I can fix this? Everything else works on the phone.

I had similar problem. My phone was unable to find the Baseband and the IMEI no. My network was not displaying though the WiFI was working. I was just rooted and installed CM7 as per their site instruction.
The final verdict to fix the issue was to install the Radio Base Band zip "baseband-N_01.77.37P.zip" and isntall as update zip option from recovery menu. Now every thing is working.
double restart
two important thing:
1. its important to try all Radios and find the best one that fit to your device\carrier.
2. another thing that important is that after flashing a new radio, you need to restart your device, twice.
sometimes one restart is enough, but in other times , if you dont make double restart - its simply not connected.
First upon there are few senior guys in here who hates noobs questions, to them " Don't forget you too where a nobiee in the beginning."
NOw my story!!
2 weaks before I brought one unlocked E970 from my friend, which runs CM11 nightly 13. The first thing I did was updating to 14 which was just released. The phone had little heating problems and gps fixing issue, also terrible battery backup due to wake locks.
So I flashed the cm 10.2 stable and found all issues fixed except the phone fails not register in 900mhz 2G networks in India (I mean weak signal in 900mhz, where other carriers like DOCOMO which works on 1800mhz are works just fine).
After reading a lot I decided to flash on nexus 4 radio (.54),but there is no hope.
Then I flash back the stock ATT_JB radio and find the network problem is resolved have all frequencies (900/1800mhz gsm) and carriers listed, but my sim is not recognizing.
Ok good, I start flashing almost every radio up there
E970,e971,e973,e977 - all gives the No sim error. ( even on LS970) ( surprisingly the all shows the same baseband also)
but all the nexus 4 radios did works, but terrible signal in GSM 900mhz. ( also experience few problems in .84 and above)
Guys I even flashed on E980 modem and find the network and SIM works amazing but no audio, speaker and demigod crash. Which can be understood since e980 is snapdragon 600 SOC.
OK I must have broke some thing lets go to the beginning, so I did the LGNPST and return my phone to 4.1.2 stock att&t.
results -- Stock rom and stock rado
problems-- not even network scan is working( error in scanning network), and of curse no SIM!!!
That's it> I rooted my phone by using freegee unlocked my boot loader and install CWM. Then flashed back the CM11 and nexus radio. Atleast the phone is working expect the volume keys are inverted.
I may have broke the EFS, but I have IMEI number and phone working in N4 modem. So the issue is with the ATT radio which may be some RIL issue I guess.
In order to get my phone useful, either I have to make the ATT radio accpet my SIM or some have edit the nexus4 radio and make it give a good signal in gsm 900mhz. Also the inverted volume keys are awkward.
To be honest I have no idea what to do next, but I strongly feels its a software error and can be fixed, BUT HOW?

you done lots of wrong things with your phone for minor network issue.
First flash Stock LGNPST to make your phone usable. And then use it for about a day. sometimes due to low signal it doesn't network.
If still doesn't work then flash EFS and Stock ATT JB modem and then try to use it.
or ask your friend if he gave you and unlocked phone or locked one or he might have bricked modem just like you are trying todo.
Flashing files for diff in your phone makes things worse and might give you Hard brick. so never flash anything of other phones. NEVER.
Your best bet is to use stock rom for a while to make things normal or else you might hard brick your phone and also if you are buying phone from someone else then first check it if everything works or not.
