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.

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 ?

Followed ICS root instructions, weird results?

So I went through the instructions of getting root on the ICS leak and got some weird results. I flashed the superuser file once and got an error. I ran it a second time after reboot and made it further but still didn't complete. I ran it a third time without reboot and it completed and seems to be working.
What could have caused me to have to flash it 3 times in order for it to take? There shouldn't be any issues now that its there and working but my curiosity is peaked as to why it did it. Any thoughts?

From reading other posts that's not a unique experience. Not sure why it happens though.

that's just how it works; i had to flash twice, well once then fix permissions, then a second time and it worked.

I left that part out, after the initial try it didn't take I ran fix permissions, rebooted then flashed again with no luck. The third time was the charm though. So nobody that has experienced this has had any troubles with it? Its basically just a weird bug that crawled out from under the table just to disappear when you came back with something to kill it with... Damn things...

I had the same issue .

I used the same process to root and mine reboots and powers off fine.
I also had the failed install flashing Superuser.. ended up moving it to the internal storage and I didn't have it happen after that. Not sure if its just coincidence or not.
Everything else seems to be working great, Rom Manager just won't fix permissions. Having no button or force close issues.

System won't mount r/w in root explorer. Anybody else having this problem?

Nope, using ES File Explorer I turned on Up To Root, Root Explorer, and Mount system as writable and was able to create a file and delete it.

I've always had to flash the su zip numerous times before it took. Don't reboot recovery just keep trying. Ide say there is nothing to worry about since its happened from day one and I've never had any problems before. Still don't have any issues :thumbup:

These are the issues I'm currently having.
I ODIN'd ICS and CWM. Installed SU (3x) and Rom Mngr.
I no longer have Home button functionality, though I did on and off after flashing ICS.
Rom Mngr. throws errors when attempting to Fix Permissions and it won't.
Rom Mngr. throws erros about the Internet, messaging, etc has stopped working when first attempting to accomplish a task.
The Power menu consist only of Power Off & Restart. Restart freezes and requires a battery pull.
Factory Reset also freezes.
EDIT: After installing CWM via ODIN and then ROM Mngr., it wouldn't recognize that CWM was installed and prompted me to install it.

GPS issues

My s3 has been acting funny lately.. the GPS seems a little wonky. I noticed when flashing a 4.2 rom.. my GPS seems to want to work..then just won't get lock on its own..I have to toggle GPS on/off to force it to work..and even then its not very solid. When I flash back to a 4.1 rom.. it seems to work. It gets lock on its own..but even then..I notice a strange inaccuracy.. I use My Tracks..a free GPS app..when running side by side with my tablet..the location seems weak on the phone..while driving in a straight line..it shows me on the other side of the highway..but near..not too fat away..then sometimes it seems on track. Now on the tablet..its dead nuts accurate.. showing me driving straight..not like I had a twelve pack first..lol..could formatting the SD card of damaged something? I wonder if all the flashing I do screwed something up..

My only fix
I have had the same problem. On CM10 my GPS works flawless but when I go to CM10.1 the GPS only works for an app if I toggle it inside the app. I have only found one fix so far for it to work in CM10.1.
Here's what I used from buhohitr (post):
Download the zip, unzip it, then copy the 2 files (gps.conf and certificate) to /system/etc of your device, reboot and try out your gps. Let me know how it goes. You must be rooted to do this.

I read on XDA, someone talked to a Verizon rep and said it's a VZW bug, not ROM/phone related. This worked for me, here's the fix:
Clear Data on Maps
Clear Data on Google Services Framework
Go to Location Services and turn OFF Verizon Location Services (leave other 2 ON)
Reboot Phone
You should now have GPS lock (hopefully)

If you can get into download mode, you're still OK - you just need to odin via PC. Check the MD5 and filesize of your root66.tar, if it's failing it's most likely a corrupt download. If they match and it still fails, what is the error message that comes up? Once you flash the stock img, get superuser and a custom recovery, and from there I hope you made a nandroid or can clean flash a new ROM. Hope this all helps.

Yeah, I've heard just Odin back to stock and then a clean flash can do the trick. I still recommend getting the app called GPS Status and downloading the aGPS Fix. Good luck!

Of course I spoke too soon when I look at the 3 choices under location settings it's missing the Verizon setting it actually only has 2 settings plus 1 location setting toggle at the top which activates the 2 at the bottom it's a different layout.. It's gone back to only working what I toggle it on and off again..
Sent from my SCH-I535 using Tapatalk 2

Hmmmm that sounds like the ROM had changed the menu layout. The problem could be a ROM related issue. Have you checked if its been reported in its specific thread?
Also, go to Google Now (or Google Search), hit menu and go to settings. Check that Google's location services are on.
Lastly, I've heard about and seen better GPS with Wifi turned on, even if you're not connected. Try that too.
Sent via SGS3 using Tapatalk

What worked for me 100% is the app called GPS Status & Toolbox. Worked flawless. I have zero issues and locks solid in less than 20 seconds. That is the longest, usually 5 seconds is normal for me. Program runs when outage GPS enabled and running google maps.

I have tried them..just doesnt work unless i toggle gps on/off..lol..but its strange I can go back to 4.1 and gps works fine... All 4.2 ROMs give me the same issue..the GPS works fine..just doesnt start up on its own when I start maps or something.. I have go toggle GPS..then it works..that goes for any GPS app..just like the one u are talking about..it sounds like your GPS was indeed coming on at least..just weak..my icon doesn't start unless I toggle it after starting GPS app of choice..

[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....

[Q] Bluetooth won't turn on

This morning, when starting my commute to work, I noticed that the S5 wasn't connecting to my BT car stereo. I checked the phone and BT was off. I tapped the icon and it did the slight dimming for a few seconds and then went back to the off state. I opened up BT settings and tapped the slider to turn it on, got the message "Turning on bluetooth", but again, after a few seconds, it returned to the off position.
I'm running the stock ROM, rooted with the hotspot mod, and the restart menu mod.
I tried restarting, powering off and removing battery and restarting, restarting and hitting the BT settings as quickly as possible, but it still will not work. Permissions on /system/vendor/lib/libbt-vendor.so are rw-r--r--, so I don't think it has anything to do with permissions.
I read a thread regarding a different phone and ROM having this problem and they fixed it by flashing a different kernel. Any ideas before I take this route?
EDIT: Just to be sure, I rebooted into recovery and ran fix permissions. No change.
Does anyone have the stock kernel that I can try to flash or Odin? Thought I might give this a try before going with a modded kernel.
Thanks

As much as I hated to do it, a factory reset fixed the problem. Still don't know what actually caused the problem.

Are you going to reflash the mods you were using to see if the problem was the same? Also, you might be able to just make a backup of your system/data/recovery and flash it over so you don't have to factory reset.

I tried the backup, but it brought the problem back as well. Not sure if it was something in the system or days our apps. Still need to do some forensics.

If you flashed off of an SD card, sometimes you can get subtle corruptions? I thought I saw something about it before..
