The APN issues thread

Hi everyone,
I figured I would start this thread to give everyone a place to post their APN issues/fixes/work arounds to maybe cut down on the questions being asked in the development forums. I will include any of the fixes/workarounds I have seen so far and try to keep this thread updated with any new ones that come about. I have learned so much on here on XDA just by searching and reading, I hope that this thread can do the same for anyone else looking for answers. Thanks/credit for all these fixes/work arounds goes out to all the OP's (special thanks to Martovitz for inspiring me to write this) Again this is just random things people have tried that have worked for them,this is NOT a step by step, THEY MAY OR MAY NOT WORK FOR YOU, and they are in no particular order, everyones phone is different:
APN Voodoo:
1) Try Holding power button down while holding volume up to reboot phone.
2) Try pulling battery out while the phone is on, let it sit for a minute, then restart.
3) Try toggling airplane mode on wait a minute, then turn it back off.
4) If simple user is selected in your APN menu try selecting T-Mobile. If this fails try deleting simple user APN.
5) Go into settings>wireless>mobile networks. -let it search, pick one, let it 'error' then select the 'select automatically' option -wait a second, press back to the home screen, wait two more seconds APN issues disappear
6) Run fix permissions in ROM Manager
7) Replace Sim card,try new UICC sim card specifically for 3g/4g devices.
8) Try flashing new ROM while in a good T-Mobile area (ie full bars of reception) to register on network
9) Try reinstalling ROM using this process:
a) Wipe cache
b) Wipe Dalvik
c) Flash ROM
d) Flash gapps
e) Fix Permissions
f) Reboot
10)
a)Turn on WiFi and make sure you're connected.
b) Go into the Market, search "APN Backup".
c) Download the program called "APNsBU (ROOT)"
d) Open the program and click on the "Backup APNs" button.
e) After that's done, click on the "Restore APNs" button. It will prompt you to reboot your phone.
f) After the reboot, open the APNsBU program, click on the menu button on your phone and click "View APNs".
g) You should be able to see "Simple" and "T-Mobile US." Turn off your WiFi and you should be good to go!
11) The fix that's been working for me 100% is to just delete the APN type on both the T-Mobile US and Simple and then make sure T-Mobile US is selected
11) Use ROM Manager to "Reboot into Recovery", once recovery boots simply select "reboot system now" and let the phone boot back up. That's it, when the phone boots back up the apn settings will be restored and data will be working like it should.
***Disclaimer: I am in no way responsible for any damage you do to your phone trying these fixes/work arounds***

pretty awesome thread, thanks for sharing your experiences

Would someone be willing to type up or link to the reason why the APN problems manifest? I really appreciate the list of (supposed) fixes, but I'd also like to know why the problems exist in the first place.

I honestly don't think anyone really knows, but I'm willing to bet with the release of official gingerbread update these problems will disappear
Maybe if everyone starts posting the problems their having and where, when, why, and how they started we could narrow it down

APN Issues only occur with not stock roms for me.

Apn issues:
They basically give u no data and when u go to apn settings there are no presets. This usually doesn't happen on first boot on cm. But when u reboot everything dissapears. Some fixes use to work for me but now data works when it wants to

Exactly my problem or when I am on wifi and turn it off I don't get data back either

See and the really weird thing is you get people like me that have never had any apn problems .... but I have only flashed Cm7 rom starting with nb#32. I haven't used any other roms.... maybe that's a possible reason why i have no apn issues.

Have u tried apn'sBU? It fixes every time for me. Usually happens first reboot after new flash (not the reboot out of cwr).
Yah, it's a crazy issue. Cm7 is the only rom I've flashed, I did a few full wipes around nightlies 38+ figuring it would have to help. Made no real difference.
Good luck.

My data/apn fix...
Okay, I guess this isn't technically a "FIX", but it WILL get your data working again until the next time the apn settings decide to mysteriously disappear.
Use ROM Manager to "Reboot into Recovery", once recovery boots simply select "reboot system now" and let the phone boot back up. That's it, when the phone boots back up the apn settings will be restored and data will be working like it should.
Wish I had an actual fix but this is MUCH better than nothing, and in my opinion easier than taking my case off and pulling the battery every time.

Any time I'm having data or signal issues, this pretty much fixes it.

Going to try the clockwork one, would like to run cyanogen but no data is an issue

APN // No data
Having the same issue here with cyanogen ... Tried many build ... I'm adding my APN (I'm sure it's correct, it's working on stock firmware) But on Cyanogen, no data (4G) HSPA+ network ....
Tried removing battery, airplane ... impossible to get data working...
Any clue ?

My first answer to any of this kind of question is factory reset. Another good option would be to looking into CM ROMs, or even LC's ICS ROM.

Factory reset? No no no...the default answer should never be straight to factory reset!
OP...are you rooted? If so which rom are you currently using?

Factory reset is your last option if you have an unrooted stock ROM. And if you have a custom ROM it is not even an option. OP, follow through with cwhitney24.

I'm just guessing, but it sounds like something that uses only mobile data is always on. Sometimes an app may not close right and hang it up. Try rebooting and see if it still does it.

I had this happen to me once with my home wifi. I ended up having to make the phone forget my remembered profile, scan, and setup again. Not sure what caused it, but it hasn't happened again.

Please help - Cyanogen Nightmare! Can't connect to cell network

EDIT: RIGHT AFTER POSTING, MY PHONE RANDOMLY STARTED WORKING. I HAVE NO IDEA WHAT I DID BESIDES POST HERE. MAGIC.
I installed Cyanogen version 7.2.0 just fine using the guide that was found here: http://www.mrmuh.com/2012/01/update-a-motorola-milestone-from-motorola-firmware-to-cyanogenmod-7/
However, the next morning I think I enabled the 2g/3g switch widget - and then my phone entered into a constant and continuous loop of "com.android.phone has unexpectedly closed" - and couldn't connect to cell service.
In a panic, I searched everywhere for fixes. I then tried a few of the fixes which instructed you to download "sqlite editor" and do some edits to the settings file. I did this, along with a couple of other network edits, resetting them to "0" instead of the "1" they were currently set to. No help.
Finally, I went into the Open Recovery system and did a full reset on cache/factory reset/etc. and then rebooted into cyanogen. Now my network won't even connect for a half a second and then crash like before - just straight up NO CONNECTION.
Now I've went through and attempted changing back some of those settings I messed around with in Sqlite - but to no avail.
Anyone with any ideas on how I can get an operating phone again, please let me know. I noticed I still have all my apps from previously, so I don't think I'm really factory resetting the phone. That could be part of the issue, I'm sure....I am very depressed and hoping for a miracle!!

Look into installing minimod recovery and then flashing the correct radio for your location after a full wipe.
If you do a google search you should find minimod. I'm on my phone or I would just link you.

OK Thanks for your reply.
However, randomly, just after I posted this - I looked down and my phone had a full 2G Connection. Went into baseband settings, enabled 850 band 3G, and now I have full 3G connectivity.
I have no clue how this happened. XDA forum is magical?
Thanks again for your reply, but thankfully I don't need the minimod suggestion as of now!!

You're welcome. You might want to go ahead and install minimod though. I made the mistake of not having it installed and flashed a new rom without the ability to select bands and was without a phone all day. It's better safe than sorry.

Good call. I'm just quite happy this is working now, but you are right, don't want that doomsday feeling again. Thanks

im having the same problem here :// i only can get cellNetwork if i restart with airplane mod.. then after i rebooted i go back to normal 3G/2G mode but otherwise i dnt get cell signal// also seems like wifi has some bugs im using HOHO CM7

Do a fresh install of HONO through minimod recovery.

[Q] Glorious Overdose V5 crashing processes

Downloaded this ROM from the second link. Thought it was a bad download, as it would go through all the setup but it seems to install just fine, but when the phone reboots, the phone process immediately crashes, can't set any accounts (accounts crash), keyboard crashes, etc. Not sure what I'm hitting wrong, I've downloaded it again, wiped cache/reset, wiped dalvik, install just the rom first, set permissions, reboot into recovery, run again, install all software (launcher, factory apps, etc), but they still manage to crash (especially phone so I get no data unless connected to wifi).
Any advice? Thanks in advance

I believe thereis an issue with wifi calling, need to look into this, see if all works when not installing this, well try wiping, flashing rom only, then go back in aroma and flash anything but the removed from stock stuff. Hopefully this will be fixed soon

I absolutely LOVE this rom. I got over the .phone crashing as it doesnt effect me much it seems just crashes twice on start-up and thats it. I didnt download wifi calling and it still crashes for me. But this is seriously otherwise the best rom ive ever used. Many kudos.

Yeah. I'm having the same problem too. Basically, the phone won't work. Everything just crashes. I hope they make a fix really soon. I love this ROM.

I find it weird that GO is the SLOWEST out of any roms I've tried...and even though I don't like it, stock isn't as bad as I thought - just has bad bloat. GO has chrashed even more than stock has, but after I just did a clean stock, its faster and both previous experiences....

Weird lag issue

I just picked up a bad esn sprint phone. Its pure stock, locked bootloader and all. I did a couple factory resets. And cant for the life of me figure out whats causing the lag. For a minute or two after boot its tolerable app drawer speed but whenever I open something (any app at all) it will hang anywhere from 5-30 seconds. Then once the app opens it will hang up again. Sometimes popping up the not responding wait or force close box. I hit wait and almost instantly its useable but laggy. Anyone have any ideas

Backup your stuff. Unlock bootloader. Flash factory image. Report back if it solves the problem.

No working pc at the moment. And why should you need to reflash the image on a factory unrooted device. It seems after i clear memory with clean master it speeds right up again for 15-20 minutes. It gets down to 11% available memory. I don't have really anything installed except xda and some tools. My hope for this phone is to try and learn how to port a ROM and want this phone to run smooth pure stock before i start so if it has a lag when i port i will know its my fault. And when flashing stock image can i downgrade without any issues

Factory images are one of the best sources to start afresh. Flashing a factory image (4.1.2 in this case) will wipe EVERYTHING and you will be able check if the lag is still present.
And since, you are working on porting a new ROM which I thing is > 4.1.2, you will not face any downgrading issues.
