[Q] SIM MODded Photon Q 4G LTE issue with GSM - Motorola Photon Q 4G LTE

Hi guys,
I normally am not a big responder or thread creator here.. Just a happy Photon Q user … but now I am looking for your help!
I own a Photon Q modded by CornholioGSM. Worked like a charm untill I got on a plane last week. (From Netherlands to Italy)..
When boarding I set the phone to flight mode.
Got off the plane and switched it back on, turned off flight mode. No longer acquiring connectivity to mobile network.
So.. went into Android testing (*#*#4636#*#*), turned Radio Off and set it to GSM Auto. Turned Radio back on.. still nothing.
Went into settings.. Mobile Networks > Network Mode was suddenly changed into “Global” and could not change it into anything else.
Factory Reset the device, again set it to GSM Auto and Network Mode was now changeable.
Set it to all kinds of different settings but it still won’t connect to a mobile network.
Everything else on the phone works fine except mobile networks. So no GSM, EDGE, 3G etc. WiFi does work.
The SIM card is also detected and eg. Whatsapp works fine too.
Does anyone know how to solve this?
Do I have to reconfigure the device or perhaps try a different ROM?
Any help will be greatly appreciated!
Grazie,
Steve McQueen

Photon Q &/or Note 3 on ting.com

Thnx for your reply RBeavers!
I did consult the SIM MOD thread.. My issue is a bit different though.. My Q has no network connectivity anymore.. at all.
It doesn't drop sometimes and then reboot to fix.
Btw: Its running stock ROM. Might be worth to mention that
Hope someone can help!

Hmmm just installed CM 10.2 .. Set the band to 800/900/1800/1900 .. Set Phone testing to GSM Auto.
Mobile Networks to connectivity to GSM/WCDMA Preferred.
Still outta luck.
Can't think of anything else other than a wire has come loose.

Maybe it's something like this?

Also, getting radio log (as soon as possible after boot) could help to diagnose the issue:
Code:
adb logcat -b radio

Happy days!!
Got it working with CM10.2!! Fiddling around with it. Set band to Automatic, *#*#4636#*#* GSM Auto, Settings > Mobile Settings > Preferred Network Mode: GSM Only
And set Use Only 2G checkbox. Magic.
These settings in the stock ROM wouldn't work anymore.
Thread can be closed. Thnx everyone for reading and replying!

Weird APN / 3G issue

hi,
I'm on day 2 of trying to sort out my wife's new Captivate, so would appreciate any help at all. Phone is rooted, unlocked and has decent signal, but I cannot connect to 3g.
I'm on Optus network via TPG (Aussie network). I've tried many APN settings, and I'm at the point where I don't think this is the issue (yes, I know this is normally the issue).
I tried going into *#*#4696#*#* and doing WCDMA preferred, and WCDMA only, made sure AUS radio band was selected and did 'Enable data'.... also no help
I've also made sure data is enabled on the sim/account. If I insert the sim into another phone, it works with 3G. So it's something to do with the phone for sure.
Optus' 3g info says "2100MHz frequency band. Enabled with High Speed Packet Access technology (HSPA)". So WCDMA is the correct setting I think.
To be clear, I've never gotted the little 3G symbol at all (or an 'H' symbol that I've seen someone mention). I first tried emulating my own Vibrant's settings exactly, which didn't help.
Any ideas would be great.
thanks.
I'm completely out of options ... is there a chance this is an issue with bad contacts? I fixed my Vibrant's GPS by prying up one of the contacts...
All fixed. If anyone else has this trouble - flash back to stock, following this guide http://forum.xda-developers.com/showthread.php?t=884364
Note - I already had stock, so no idea what the hell was going on, but whatever.

[Q] Unable to use 3G on unlocked HTC Desire

Hi,
I am unable to use 3G on htc desire. I have set the correct APN. The problem is that when I choose "WCDMA" as the network mode, it automatically switches back to "GSM only". The place where I live has no problem with 3G availability. I feel the problem lies more with my handset. Can someone please help ? Is there anything that I can do to get rid of this problem. My phone has lost its warranty since I unlocked it.
Have you tried any other operator sim card? It's a good troubleshooting to do when this kind of problems happen...
Had problems like that before and it was an incorrect APN setup.
Thanks for getting back. I tried with a different sim and a different operator. They were also not successful. APN setting is perfectly right for the current sim. The APN settings were given by the operator.

Are you using any kind of widget to switch APN on / off, 2G/3g ?... I noticed that for example, Widgetsoid can mess with 3g connection so much that sometimes you need to remove it and reboot the phone so you can get things working again.
Try using another SIM card too. It may give you a clue on what's going on: wrong settings / card with no data activated / etc ...
I am not using any widget to turn on/off the 3g. EDGE services work on my mobile while 3G is not working. If I use the sim card on to a different mobile, 3G works fine without any problem. Tried using another sim card with 3G data activated and that also did not work fine for me on HTC Desire.

3G not working

My phone is a Nexus One w/ CM7 installed with the latest radio and I live in the US. I read to go into the Phone Info settings and switch the 'Preferred Network Type' field to WCDMA Only to force the phone into 3g mode but when I do this I get the message 'fail because Radio not available' under GSM disconnects DATA. I tried flashing several different radios and this did not help.
I get a connection when using WCDMA Preferred but I am restricted to the E or the G symbol in my notification bar. I want the 3G symbol!
I am out of ideas here!
i got exactly the same problem ... !
might help...
have you tried toggling airplane mode off... then on... then toggle data off... then on?... it might work... then again, it may not... dosent hurt to try i guess...

[Q] How to make LTE/GSM default?

some time ago i set the phone to LTE in the testing menu to see what LTE networks it could see. it saw them fine but not for the network i use yet.
the thing is ever since then everytime the phone reboots it seems to default back to LTE only. soi have to ga back in to the test menue and set it back to LTE/ GSM to get the signal back.
Help! why is it still doing this and how can i fix it?
Go to Settings, More... under Data usage, Mobile networks, Preferred network type. Make sure the radio button for 3G is selected.
so i cant leave it on 4g preferred? 4g should be coming to my location in the next coulpe weeks so id not want that to be perminant.
or will setting it to 3g reset things?
ooooooh, did as you said rebooted, 3g locked on. sat back to 4g preferred and rebooted, 3g locked on.
yey! thanks, i dont get why it worked but much appreciated.

Please help! No 3G or GSM, can't call, but LTE works fine.

I really need help with my device, I searched all over XDA and no-one seems to have the same issue as me.
Here is some information:
1) Nexus 6P (H1511)
2) 6.0.1 Absolute stock, no rom, no root, no custom recovery. Build number MMB29P.
Recently got a new Nexus 6P and imported to Russia. All of the major bands here are supported. And the phone worked excellent for a few weeks, but then it lost all 3G or GSM connectivity. Just randomly,didn't do anything with it, the only thing I did is move to another city but than I got back, the issue didn't resolve. LTE works perfectly but can't call or receive calls, can receive sms though. Reseting network settings and factory reset changed nothing. Tried manualy set network to WCDMA or GSM with *#*#4636#*#* command, the moment I switch to anything besides LTE the connection is lost. Contacted the provider, no problem on their side, my SIM works good in other phones, my phone with other SIMs - no.
I don't think it is a hardware issue because a few times I managed to get everything working after an hour of switching networks and bands with no particular order in the *#*#4636#*#* testing mode.
After a while I figured that if I set phone to "GSM only" on USA bands in testing mode, but at the same time set it to "LTE prefered" in the normal network settings menu. I am able to set phone to Band mode 7 and set the network back to 2G in network settings keeping it on " GSM only" the whole time and only after this compicated algorithm and after a reboot 2G and 3G starts working. But any reboot after that revertes everything back to only LTE stage. Also if I get everything working but than reset network settings everything stops working again.
I have no idea what caused such an issue, I really hope someone can help.
Sorry couldn't post screenshots because of the "10 posts rule".
