Network settings keep forcing GSM/UMTS - Motorola Photon 4G

So, while tweaking settings using *#*#4636#*#*, I've apparently disabled the MoPho's recognition of the Sprint network entirely, and now the phone continues to reset itself to GSM/UMTS only in Network settings, even after reboot, and even after i change the settings manually to "any CDMA" or "Sprint" after the fact.
4G however, works.
(shrugs)
This is a first for me, and a headscratcher. Definitely don't want to go the hard reset route. Any suggestions of what I should be looking for?
**Update** - Have somehow managed to get it to stop forcing itself to GSM/UMTS, but will now only set itself on Automatic, and will not allow me to set "Any CDMA" or "Sprint only". Clicking these options won't stick, and just reverts to Automatic.
Preferred network type in Phone Info is "GSM/CDMA auto (PRL). I've turned the radio off/on several times, and it still shows as searching for service.
Sigh..
**Update #2** - Factory data reset didn't do the trick; phone still can't locate network. I'm sure this has got to be an easy fix. Anybody?
**Update #3** - Sprint couldn't figure it out either, chalked it up to a bug, and swapped out the phone for a 3D since they didn't have any MoPho's in stock. Would still be curious to know if anyone else ever encountered this issue..

Just out of curiosity, coyld you try putting in a sim chip and see if your phone recognizes it? Also, what is your baseband?

That is indeed a bug of the stock firmware. Only way to fix it is to sbf back to stock. Hopefully you are not on the latest OTA (235) as I believe you can not sbf that version (downgrade).
Did the same thing myself by tooling around in the debug menus.

Encountered the same issue when I selected USA band. Did several things and nothing good happened. Finally flashed 235_radio_only.sbf from peetr_ and it worked. GSM 3G is working and 4G seems ok but unable to test it as I am not in US.

++please>>>helppppppp

my atrix was fine today, but the signal suddenly disappeared from my carrier, and not make calls anymore. when I put my SIM card in another phone it recognizes the signal from my carrier and I can call. any ideas?
thanks
HELP!!!!
please
can be a problem in the GSM frequency?? Because I can find other carrier..
may have burned only one frequency?
how to check?
is possible to burn only the 2100 mhz frequence??
1. Try to search network in setting. Than choose your carrier..
2. Last way is to flash your atrix.
Power off / power on the phone. Double check your network and APN settings. Otherwise you might be looking at a factory data reset...

Last night at this time, 4 people I was with had full bars on AT&T, none of us could download/upload or make calls. 2 iphones, 2 android. Someone with a Verizon phone was fine.
Maybe your sim card broke?

Are you still without a signal?
Have you tried the factory reset yet?...
if you can, try someone elses sim card in your phone. Its a long shot but I have seen it work in the past. If it works, takes it out and then put yours in. Otherwise Flash SBF, or take it in for warranty replacement.
Just out of curiosity, have you installed any weird 3rd party apps recently?...

Might not explain the calling, but do you have anything in your APN list?

phone automatically disabling network

hey guys,
having an issue with me phone!
it randomly turns off network connectivity.
eg, disables reception so i can't make calls,sms or use data.
i have tried rebooting phone
i have tried doing factory reset
but it still randomly does this at times.
also when i go into my network settings i get PROCESS.COM.ANDROID.PHONE IS NOT RESPONDING!
so i can't even turn on/fix/choose network!
*edit*
i can sometimes access my network settings without the error but i have now found out that EVERYTIME i reboot the phone my network is disabled on startup and i have to go to network settings, then get the error and force exit then reopen it again and it enables the network!
could anyone share some light?
thanks.
Ahh , old error..
which version are you running on currently...?
Join the Club.
I had 2 Razrs both had the dreaded self power down issue so a manual power on was the only way to turn it back on. One of the phones the 3rd actually just died on its own no batter power nothing. On all the phones I had this network issue, it would be at 4G then when it switches to 2G it actually turns the network off completely and then goes to 2G. It does this on many occasions and sometimes I'm wondering if I'm on a call and signal strength goes down I wonder if I will be cut off. Had all the phones have issues weeks apart and awaiting the return of the 3rd phone from the service center I can't offer much more than what I have experienced so far. What I have found on this phone is that the signal quality isn't great in fact the SG2 I"m using right now on average has a better signal than the Razr. I'm also wondering if the self power down is attributed to the loss of signal, where the phone continues to look for a signal and don't find one and then powers down?
Try to check your smart setting.

XT 310???????????????????
I think its a typo
anyways, I had the problem.. but then I upgraded the baseband to 85P and it is okay now..
If the baseband is correct then, install the application CATLOG and start logging... in case the phone throws the error, catch the data and post it here..

No 4G after installing custom rom

Hi, I have a Verizon Droid Razr Maxx and I have been rooted for a while with the stock ICS rom but I wanted to try one of the custom roms out there. First I tried MIUI and I had no service then I did black widow and It had service but only 3G/1X. I restored back to stock with DroidRazrUtility 1.8 and I am still only getting 3G/1x.
I have another 4G phone that is getting 4G service so it's not an outage. Also, I tried swapping the sims in the phone and the Razr still won't connect to 4G.
Does anybody know what's wrong?

have you checked and made sure its not on cdma only.
Sent from my Droid Razr using xda app-developers app
Ok I think i can fix your problem. Try this. First off, in ICS there is no way to check for settings as "CDMA ONLY" like Gingerbread. They removed the option in all their infinite wisdom. Download this program "Phone Info" from the market place. GO to the first option of "Phone Information". Scroll to the bottom, you should see a bunch of fields and one states the frequency of the antenna. It will be above the "Turn off Radio" button. It allows you to change it to literally anything available whether the phone can find the signal or not. It may be on "CDMA only (auto PRL)" This is only 3g as you probably guessed. Make sure it is on this "LTE/CDMA/EVDO/GSM/WCDMA". This is the normal frequency and will do 4g/3g/1x. Hope this helps

Sorry, don't think I said to check under mobile networks. Guess I should have specified, dial *#*#4636#*#* you can now pick cdma only or make sure its not chosen
Sent from my Droid Razr using xda app-developers app
Thanks for the suggestions. I went to the phone info page and tried the suggested settings and even tried a few other's but nothing seems to get a 4G connection.
Again I checked my other 4G phone and it is connected to 4G so I know it's not an outage.
I changed to to LTE ONLY just to see what would happend and it indicated that the radio is off but with no way to turn it on. You know the button that says "Turn on radio" won't toggle like it will on the other settings. I am not sure if that means anything.
Ah well ibforgot about dialing the service number. Phone info takes you to that menu anyways

mobile network not working on cm 10 or cfx roms

hi guys i am having trouble with the mobile network on just this rom. i only have 3g in this area (cant wait till january so i cant test lte, but it is most likely the rom. i just cant get the phone to connect to mobile network. do i need to flash newer radio? other stock moded roms work fine. No good on cyan mod 10 roms ethier
You could try disabling it from looking to LTE service in the mobile networking options - Maybe they happen to be turning it on to test and your phone is trying to connect?
It's under Settings => <More> => Mobile Networks => Network mode => Change to CDMA / EvDO auto
I already tried changing no luck thanks for reply
Very similar in theory.. But also try this.
Go to the dialer, hit *#*#4636#*#*, go to phone information, and change to CDMA auto (prl) in the drop down list there.

ya i tried that got it to work. now I am having the issue where when i receive multiple mms's In one single text
(i got mms to send and download using an alternate apn found in Baffles thread under android development if you cant get it to work try rebooting after you restore the apn)
the app itself tries to open it as a slide show then instantly closes, this is a problem with the app since i downloaded an alternate messaging app and it worked fine. the reason i care is because i wanted to have the stock app working due to the "reply in notification bar" feature. can you guys try out receiving multiple messages sent at the same time from one phone to another and see if it works or if any one can link me to a working CM10 apk messaging app

[Q] Can't use anything but wifi, please help!

I was playing with the *#*#4636#*#* menu in CMX and changed my band to Australia. I then lost all connectivity but wifi. I figured I'd just nandroid back to my fully functioning CMX - I was wrong. After restoring the nandroid, the phone still won't connect to anything but wifi.
I then saw this post and flashed meanbean to use the Sense dialer.
None of the instructions worked! When I try to ##786# reset all my data, the phone will do its thing and then boot back up into meanbean and ask me sign in to my accounts.
The DEVICE_PROVISIONED=1 doesn't exist in my build.prop as seen in this post so I can't use the simple method. :crying:
Any help is greatly appreciated. I only have wifi while I'm at work, so in 5 hours I'll be screwed.
EDIT: Almost fixed it! I nandroided back to CMX and tinkered with some more advanced settings. I figured I can't hurt anything more than I have. It's now connecting to the network and 3G, but says it needs activated. Finally, progress!

Thanks guys, I did get it fixed. Once I got some sort of connection reestablished I needed to activate the phone. I called Sprint customer service from my work phone and they refreshed all my data/connections. That allowed me to connect to the network, but not use it (if that makes any sense). I then downloaded the deodexed stock rooted JB ROM from here. After flashing that and booting into it, it said "hands free activation" and then starting updating the PRL before asking me to set up my accounts.
Hopefully my story helps anyone who gets caught up in this issue.
One more thing, upon reinstalling my cmx nandroid, I checked the build.prop file and it had the DEVICE_PROVISIONED=1
I changed it and that's how I got the phone to reconnect to the network (still no use of the signal though at that moment). That's when I flashed to the stock rooted ROM and everything was fine from there.
