Cannot connect to 3g

Hey whats up guys...im really not sure what the problem is but maybe some one has experienced with before..
My droid incredible cannot connect to 3g service...i tried installing all different kinds of roms even the latest gingerbread releases but still nothing.
Some times i allows me to connect to 1x but then you see the "3g" on the top but then it instantly disconnects.
Ive so tried 3 different radio from the NIS business sense release...all failed..
Any ideas?!?!?
Or if i just need the stock radio??

Aloha! I'll see if I can help.
1) Do a nandroid backup in recovery.
2) Wipe data/cache/dalvik cache then flash rmk40's gingersense leak: http://forum.xda-developers.com/showthread.php?t=1087077
3) Reboot and skip set up. Turn on 3G and even test it out for a bit. You should have whatever signal you are used to having return.
4) reboot into recovery and wipe cache, then go into advanced and wipe dalvik cache
5) Restore your latest Nandroid backup
Let me know how this works.

How would this fix any 3g issues by flashing a new rom and then returning to you old Rom with a backup? I seem to have an issue changing from 1X to 3g causing me to restart my phone at times to pick up the 3g signal again.

Primarily, the people who noticed this issue were/are folks who try out the various gingersense roms available. I've been a member of XDA since January and haven't noticed users in large numbers have issues with 3G until these roms came out. Whether it's due to there not being an official base or what, idk but many users have had these issues with 3G since the May unofficial gingersense leaks:
1) 3G being present and fully functional then disappearing from the notification bar altogether even while still being enabled in Settings
2) 3G signal dropping down to 1x and not displaying again until you perform a reboot.
I have experienced this issue and know this resolved it. This rom as well as Incubus26jc or JoelZ's stock OTA gingersense leak, for whatever reason, are a solution to resolve the 3g drop issue not the only solution. Incubus26jc, JoelZ, and Nils each have recommended and note this is a fix. My (non-fact and own) answer to you would be I believe since these three roms are the unaltered and "(un)official gingerbread Sense" files, they recorrect the 3G signal that is going awry.
Try it and let me know how this works. You don't stand to lose anything except a few minutes haha

This solution fixed my problem.

Dang it actually worked. Wish i had done this a while back. Thanks for the simple fix.

Not a problem, I'm just thankful there's a fix.

Accidentally worked for me too
I had the same problem on CM7. Flashing back to my stock 2.2 Android backup fixed the problem. Flashing back to CM7 and OMGB caused the problem to return. I am on the leaked ota now, I have flashed the gingerbread radio, and I am having no 3g issues. I wish that I had found this thread earlier.

Had this exact issue with synergy rls1 and was also told to flash the rom above to fix it. It worked for awile but then 3g issues would return again, even on non sense 3 roms and even on my old virtuous nandroid. If just flashing the above rom works for you and permanetly fixes it thats cool, but if your like me the only fix is to revert back to compleet stock and i mean compleet stock rom radio recovery boot img everything the only thing not stock would be you still want to have s-off as a matter of fact make sure to check you are s-off before going stock. Once stock you need to do a factory reset from the settings menu. What this does is it compleetley wipes your phone back to stock including wiping vzw programing, wich is the key to fixing 3g. Once your phone reboots from the factory reset you will be prompted to dial *228 option 1 to reprogram your phone. Once reprogramed your 3g will be fixed. From there flash clock work or amon ra recovery and then restore your favorite nandroid or install a new rom. I personaly would stay away from sense 3 roms as after fixing mine with the above steps i not thinking installed another sense 3 rom and broke 3g again making me fix it all over again. I have stayed away from sense 3 and havent had any problems since. Note if you have a compleete stock nandroid you can just flash that then flash stock recovery and radio do the factory reset .....

Well this is why Android is all about choice.

Well, I tried to install rmk's rom and that didn't work. I also tried to go back to stock with the RUU and the PB31IMG.zip file to do a factory reset, but that didn't work either. Are there any other suggestions that I can try?

If an ruu and a factory reset with new programing didn't fix your 3g issue its possibly hardware related. Can you still connect at 1x speed?

No, I called Big Red and they're sending out a replacement phone. I'm one of them weird people that don't use their phone as a phone too much, but I realized that I couldn't make or receive phone calls or texts either. We got that issue fixed, but they couldn't get the data working.
I guess the world of root is gone for me since it will probably come with Gingerbread on it already. Oh well, I'm probably going to buy a new phone in December anyway, so I'll have a new Dinc to put away in the drawer.

Looks like they are sending me a Rezound...JK. Actually, it looks like they are sending me an OG Incredible. I'll know more tomorrow and will let you know.
Thanks for the link to the root method. I have been studying it and I have all the files downloaded just waiting.
Edit: I did get an OG Incredible, but it came with Froyo on it. I should be good to go as far as rooting it goes. I think that I have an SLCD model though which sucks.

[Q] Generic network failure... HELP!

Let me start by saying, I have searched all of the treads for my phone, and the ones suggested before posting a new one, with no luck. I also searched all over other sites for an answer, about 3 hours now, and still nothing that quite fits my problem..
I have a Verizon HTC Inc2
-running 2.3.4
-Virtuous Unity v2.39.0
The problem I keep running into is that whenever I flash a new rom, or do a factory reset with clockworkmod, I can never get my phone to send or recieve MMS. It always says, generic network failure. I have tried with the HTC messages app and handsent app, both failed. The data icon in the notification area usually does not even show activity. I tried wiping the cache several times, restarts, changing data and wifi settings but to no avail. Funny thing is, I can restore my phone to the first backup I made, Gingerbread 2.3.3, and then MMS works.
Any ideas as to what may be happening? I can give you any additional info you need or ask as well. I'm not a total noob, but I feel like one right now. I just can't figure this one out on my own. Thanks!

General Network Error is when the system returns an error stating that you have no connectivity to send a message or an MMS (at least from my experience w/ it). I have this issue a lot with any messaging on my end because of shoddy reception. Which other ROMs besides Virtuous are you flashing that are giving this error? I know for a fact the CM7 has been having a LOT of issues with data connectivity. The last ones I remember hearing about with working data is #79 (or was it #80, I can't remember) and #85 and for a few people, #92.

I do have plenty of reception, always around 2 to 3 bars. Sorry I worded that wrong in my post, Virtuous is the only and first rom I flashed. I did it because Verizon OTA updates kept freezing my phone and I would get the blue android with the !. What I meant was, even when I did a factory reset, my MMS wouldnt work. First time I got that error, I was able to use bootloader and make a backup of eberything, then did a factory reset/wipe data and thats when I first noticed MMS was not working. So I copied the backup to my laptop, did another factory reset and format SD card, then I copied the backup to my card again, and did a restore with that backup. I restored data, cache, system, and boot I believe, and everything was back to normal and MMS was working. Unfortunetly I kept getting the OTA updates and each time, same problem, so this morning I read on a forum that a custom rom would prevent OTA updates, so I flashed Virtuous. I just found it odd that a normal factory reset, with no custom rom, would prevent MMS.
One more thing, not sure if its related, but I keep recieving messages from #6250 that say "VZWNMN: 1." Google searched that, most responses in forums are people saying they get the same thing and that Verizon told them they know nothing about it..

Have you tried a different radio?

People on CM were complaining of the same exact issue. They'd get bars of reception but MMS was just broken. I was just stating that when I try to send a message thru verizon and not google voice, I often get the same error message you're getting, which means that the data is being prevented from going out. I probably should've clarified that a little better lol. When you installed Virtuous, did you do a wipe data/cache and a wipe dalvik cache?
Also, if you restore back to your Gingerbread 2.3.3 that's rooted and your MMS is working fine there, then I don't believe it could be your radio. A possibility would be the kernel, but I doubt that Virtuous would package a kernel that would crash the MMS function. And since it's any SMS/MMS app, that knocks out the possibility of it being application based. The only thing I can suggest, would be to test out another ROM. If you're looking for sense based roms, go for BAMF's (http://www.teambamf.net) or Newt's Incredible 2 HD (http://www.themikmik.com). If you're looking for an AOSP based rom, go for CM7 (found on ROM Manager or at http://www.cyanogenmod.com) or MIUI (ROM Manager again, or http://www.miuiandroid.com). If you want a hybrid, I would suggest Skyraider Zeus (http://www.teambamf.net) or Gingersense (it can be found in the development portion of XDA). Remember when you flash a rom for the very first time, I'm sure you know this already, but you need to backup your rom first and then wipe data/cache and wipe your dalvik cache. Not doing either wipe before installing a brand new rom for the first time can cause unforseen errors.

Ok I found the answer while actually looking for new radios, so thanks for the post! haha
For all you out there who might run into the same problem, this is the solution I found..
Instructions to fix MMS (by xelsewherex)
1.Go to the market and download apn backup and restore (Market Link APN B&R).
2.Create a folder on your sdcard named APNBackupRestore if it doesn't exist already.
3.Copy this file, ht tp://db.tt/9Ao5ErR, to APNBackupRestore folder (If you aren't doing this on desktop, hit menu now in xda and choose browser. File is an xml and your phone will not know what to do with it. Long press the link and use 'save link'). This is an XML doc, sorry but since I'm new I can't just post a link, just remove the spaces between ht and tp.
4.Run APN Backup Restore and press Delete Apns and then Restore from the downloaded file.
5.You should be good to go from there. MMS should now work and the softkey lights do as well.

[Q] (Telus) Can't make or receive phone calls, "Call ended"

For some reason, my phone randomly has lost the ability to make or receive phone calls. Any time i try to place a call, it simply says "call ended" before even attempting to dial. I have not made any major changes to the phone recently. This seems to have happened out of nowhere. Data and text messaging work just fine, but phone calls won't.
My phone is rooted and I have the leaked Touch Wiz Jelly Bean rom installed. Also using CWM recovery.
I have tried pulling the battery for 10 minutes, and I also wiped cache/dalvik then did a system reboot through recovery, to no avail. Is there anything else I can try? Would prefer not to have to do a full data wipe if possible. Unfortunately I can't even call Telus (my carrier) to ask them for advice, due to this problem.

Is your IMEI# intact? Maybe try a new SIM card? Go back to stock to see if that fixes it. (I know you said you'd prefer not to wipe.)

Just to rule out any ROM related issues you could always make a full backup from recovery, then full wipe and flash back to stock and see if the problem persists. This way although you did wipe you can revert back to you current setup in a matter of minutes like nothing ever happened, if the problem is not fixed by going back to stock.

Yep IMEI is still there. Anyone have any other suggestions before I wipe and flash back to stock? I'll try a new SIM card if wiping and re-flashing doesn't work.

This seems like a good idea, I think I'll have to go this route... thanks.

Okay so I did a full backup using CWM, then wiped everything. Attempted to re flash the stock rom but ran into an issue and decided to try a different rom instead just to try it out.
Dialler worked fine on the new rom, so that was great news. Then I attempted to sync my contacts and everything with my Gmail.... But nothing was there. Apparently I somehow lost all my contacts!
So, freaked out, I immediately reverted to my Cwm backup, which thankfully restored everything. Just for the hell of it I tried the dialler... And it worked! So.... Yeah I have no idea what exactly fixed my problem in the end, but I'm just happy its working.
Thanks for the suggestions everyone!

Sounds like the dialer app was borked somehow, might want to look into those sync settings though. I had an issue one time where the contacts i added to my phone were saving to the phone and not as gmail contacts. To check you can just log into gmail in a broswer and look at your contacts, make sure they are all there. If not you can go to your contacts on your phone, press menu and export to a .csv file. This will move all contact info into this file and you contacts will be blank, at this point simply find where you saved the .csv and import the contacts which will give you the option to make them gmail contacts. Then all you need to do is go into gmail on the browser again and delete and/or merge the duplicates.

Okay so I left my phone as-is for the past couple weeks until earlier tonight. I made a backup with CWM, then I attempted to flash a couple new roms. Did a cache/dalvik/system format/factory reset before each rom installation, then made sure to format cache/dalvik and fix permissions after each installation attempt. The roms installed fine and everything was working, except I lost use of my dialler again! So I reverted to my backup, but the dialler problem has persisted, just like I described in the OP. The way I "fixed" it last time, was to restore my backup....but that isn't helping this time...
Anyone know what else I can try? IMEI still intact, getting mobile data, wifi, MMS, etc... just can't make or receive calls again.
I should also mention that I a while back, before I tried rooting/installing any custom ROMs, I made a backup of my EFS folder on my phone... should I attempt to restore this?

I had a similar problem messing around with lte, and found the above fixed the issue.

Strange occurence of phone constantly restarting.

Hello,
I have owned a Sprint Galaxy S III since August of 2012 and have been using it pretty much flawlessly until this week.
To give some history, I rooted it once it became a common thing to do and have CWM-based Recovery v5.5.0.4.
I have loaded many different roms - cyanogenmods, m.o.a.r., wicked, miui to try out and many others and have never had an issue.
I recently upgraded to M.O.A.R. v 6.0 at home and everything seemed great - loaded apps, settings, etc. The next day on the way to work, the phone restarted by itself. I thought was strange but chalked it up to a new rom issue. When I got to work, the frequency of the issue increased to the point that the phone was no longer usable as it would just continue to restart, boot, etc.
Restoring the rom I previously had did nothing to help the issue.
I looked up online at possibilities and came across the SD card issue. I replaced it, but still occurs. I've tried a few different roms and no matter what, it seems to continuously boot and restart based on certain locations that I am in or am passing through.
Today, I turned off 4G LTE as preferred mobile network and it seemed to keep the phone on. I have not done extensive testing, but could this be an issue? I am able to use 4G LTE at home with no problem as well as other areas, but it seems that once I am in or pass through certain locations, that it is crashing my phone? Maybe the GPS?
Are there any tips or suggestions of what I can do or try? I am at a loss as to how to fix this when it has not been an issue up until this week after flashing to MOAR v6.0. I've wiped data, cache, dalvik, many times and retried but still is happening.
Any feedback would be much appreciated.

At first it sounded like sudden death syndrome (a power button failure) but when you said turning off 4G fixed it that is very weird. Have you tried asking in the M.O.A.R thread?

Are you restoring any System Data ? I would suggest doing a Clean install. Meaning a FULL Wipe : System - Data - Dalvik - Dalvik Cache - Factory Reset ( 3x's ) . I also like to wipe Internal Storage. But that's up to you. Then Flash the Rom, and let it Boot. Do not load anything, or tweak anything. Just leave the device alone for the first 5min. Then test it to be sure everything is working correctly before loading apps, or doing any settings.

Just to update...
I clean installed MOAR 6 again - this time I upgraded CWM to latest version. I clean wiped data/cache, cache, dalvik about 3 or 4 times. Once it reinstalled, I noticed the data wasn't working at all so I did that ##72786# (forgot numbers off top of head) that reactivated phone. The data came back and I thought this was going to solve all the issues...keep in mind I did all this in the evening from home last night.
On the way to work this morning, sure enough once I got in the vicinity of work, phone restarted a few times. I was quick enough to catch it one time to turn preferred mobile networks to 3G first and disable 4G... my phone has not restarted for the rest of the day.
It's great that it seems the issue is isolated to 4G, but I don't understand how it can be fine in some areas and not in others. For instance, at home, 4G works just fine.
I think I will try to go back to stock or try an aosp rom. I've seen in some places talk of MB1 and MD4...is there a way to tell which I have or is that related to anything?

Actually, yes - I have been putting my gmail account information in and it has been syncing the apps. It's just so odd because I haven't had issues for over a year and I don't recall installing any new stuff.

well, now it happened at home when turning on 4g... damn.

You did not mention wiping system. If you do not Wipe system, and also Factory Reset then it's really not a Clean install. I would still suggest a FULL Wipe, and Clean install. Then run the Device for a while without adding anything. See how it performs.

I ended up just flashing this - http://forum.xda-developers.com/showthread.php?t=1904099 to stock with flash reset.
I am not sure about wiping system - I always just follow the steps of the rom wipe data/cache/dalvik. I will have to research on how to wipe system.

If you never wipe system you are definitely going to run into problems.

You just do it in Recovery before you flash. If you look at my Sig on a PC / Internet Mode there is a link on how to do Full Wipe before flashing a Rom.

No call connection until restart and no rom change

I have 2 problems.
First since a month mine and my wife's phone started to have no connection after dialing some number. We both have the same issue. Let's say I hit to call my friend Tony. SO after pressing name I see connection sceen, I see time of conversation, I see bars but no voice. The person I call to hears me. I tried with different people. Same issue on both phones.
After restart calling is normal. Airplane mode off/on doesn't help.
On June 2014 we finally decided to switch roms. So since then we have Cyanogenmod 10.2.0-hercules (4.3.1). It was alright, beside problems with camera, 30% of photos and videos have defects /artefacts.
SO I thought maybe changing rom will help.
I spent whole day on searching stock roms but all files are deleted and i can't find neither one of last 4 versions.
So I thought I will change rom to earlier version of Cyanogemod. It didn't help.
Today I spent few hours too and finally decided to change rom to 4.4.2 | HellKat (first that succesfully wanted to download).
Something went wrong.
I thought I was doing everything right and there are no tricky parts but I guess I forgot to do something or... maybe something is wrong with my phone.
So I'm using TWRP. First I hit "factory reset", then "advanced wipe" and and wiped everything beside sdcard.
Then I installed my new rom, after few seconds, it shows "failed"
So I wiped everything again and tried to restore my backed up rom.
It showed "failed"
SO I wiped everything again and installed my current rom.
It shows "failed".
I started to worry and to think that I just want my old phone back, at least it works... sometimes.
I hit reboot, wipe, and install again my current rom.
Success. (Maybe reboot after wipe is needed? or maybe it's coincidense)
Finally.
I hit reboot and installed gapps.
So I was almost happy that i could go back to where I was.
Not quite...
I started to download my apps.
On second one screen went black.
Actually it powered off.
I tried to turn it on but it was only showing Samsung logo and black screen after that.
I went to TWRP, wipe, install current rom 3 times.
It seems that restart after installing makes phone bad and I can only see black screen without even booting. Ewentually I found out that now I have 60% chance that if I hit reboot I won't be able to come back to my system.
I will have just black screen and the only way to have working phone is install new rom again and not restarting.
Or maybe it's just coincidence but I don't have time to play and spend another hour on wiping, installing rom and the gapps and apps.
I hope you guys see some stupidity or some detail in what i did wrong.
I hope that maybe one of you will actually will be able toi help me with chagning rom the right way or to fix that connection issue.

same, sort of.
I have similar issue. I cant make calls unless i reboot. And it seems when i open an amount of apps, the calls just dont work. I dont know what to do.

Make sure you're on the latest TWRP, earlier versions will not successfully flash newer roms.
As for the voice thing, did you have snapchat installed? It's been reported to occur when you have snapchat installed.

Funny fact, before you wrote we have been testing our phones and found out that it is actually snapchat who makes a problem wih calling. We uninstalled it from botrh phones and 3 days it is ok
I will install new TWRP , hopefully there is newer version.

Just a heads up, Google Hangouts Dialer has the same effect as Snapchat as well.

Is there any way to avoid this? i use snapchat often, and removing it would be a loss :/

There's an older version of Snapchat that works without booking your audio. Search the threads for it. If I come across it anytime soon, I'll return with the link.
