Atrix wont connect to cell towers? - Atrix 4G Q&A, Help & Troubleshooting

I was sitting here playing with my Acer Iconia A500 tablet, and went to send a text to my wife. I noticed that I didn't have any service which is strange since I have full bars in my room normally. Toggled airplane mode on and off, restarted the phone, even did a factory reset, but the phone just won't connect to any cell towers. There is no physical damage done to the phone, and it worked perfectly fine an hour before this. I was running CM7, but now I'm back on stock since AT&T said they would send me another. However, I apparently bought a refurb so the 90 day warranty is already long past which means I have to fork out for a new phone.
I'd really prefer not to. I'd like to just get the phone working properly again. Anyone have any ideas?

Reset your apns or try doing a fastboot wipe. I had that happen when the first one doesn't work do a fastboot wipe and then if you want use a fruitcake of your choice.

[Q] No service [solved somehow but more questions]

I got a droid eris from a friend who switched to that apple thingy. It is still going to be a bit before I can get it activated, so I started playing with it. When I first got it, he had wiped and factory reset it, and it would connect to 3g and get signal. I skipped activation for now. Here's what I did in order:
I followed this guide http://theunlockr.com/2010/09/22/how-to-root-the-htc-droid-eris-unrevoked-method/ to get clockworkmod recovery installed.
I installed this rom http://forum.xda-developers.com/showthread.php?t=944430 and once again just skipped activation. I set up wifi and discovered the world of android
Today I noticed there were no signal bars and an "x" by them when I turned off airplane mode. On the lock screen it said "No Service". My verizon razr gets full bars so I know I'm in range. After trying a few things like reflashing cyanogen, I followed this: http://forum.xda-developers.com/showthread.php?t=792026 and used the rom that also flashes the radio.
It's now un-rooted, clockworkmod is gone, and its on the stock 2.1 verizon firmware. It still says "No service". I'm at a loss. Did I permanently destory this phone somehow, or is there a way to fix this and get cyanogen back on and working with service?
Update: After trying activation about 10 times and constantly getting a no service error, I decided to try to manually program a verizon prl. I went to emergency call and did a ##3424# to go into usb programming mode for QXDM. Out of nowhere...SERVICE! I backed out and hit Activate and viola! Automated voice lady was there to tell me it couldn't activate(yet). I powered the phone down and put it on a shelf. I'm not touching the dang thing until I get it activated. Now I'm wondering a few things. First, what the heck happened? Second, after I get it activated, is there a chance this will happen again after rooting and installing cyanogen?
As soon as you activate it, it should be fine

Right, but the state it was in I couldn't activate it. I somehow randomly got it to be able to activate again if you see my update tho.
I just know from experience that when I forgot to pay my bill a while back, I did not have any service bars or anything until I called them up later that day and reactivated it. It seems like when you first got the phone for some reason even though it wasn't activated it showed that the phone had a data signal. I could be misinterpreting the issue though.

I've had that happen a couple times flashing themes.
Wiped data/cache fixed once other time never figured it out, just reformated sys/data/cache and flashed sbf.
All was back to norm then. :s

That's weird. But from a first boot 100% stock the phone still connects to the network. Otherwise there's no way to get it activated. So no matter what, when functioning properly on a cdma network it should have bars if you're in range of a tower. Now it is functioning properly, and I have signal at the initial setup and activation screen.

Data is dead after removing and reinserting sim. Help?

I have been running custom roms on my droid since the root explot was first discovered, and I have a rooted xoom as well. Last night I rooted my thunderbolt and installed the debloated rom. I don't think it is even related to my problem, as it still worked fine after doing this, but I thought it was worth mentioning. I removed the sim card today, just to prove to my brother that it did indeed have a sim, and after reinsertation, my thunderbolt has not been able to connect to a data network. I do not live in a 4g area, and I have tried reseating the sim several times. I can make phone calls, wifi works fine, but I cannot get the 3g icon, and the browser won't load if not on wifi.. I'm starting to get scared. I can't think of anything else to try. Any suggestions?
EDIT 1: I have intermittent 1x data, but I never get 3g. And when I say intermittent, I mean I get it like right after a call for maybe a minute, then it goes away.

I had this same issue as well when I removed and reinserted my SIM card. When I booted back up I was stuck on 1xRTT. After making a call, they phone locked back on to LTE and everything was good after that. If it still isn't working I would recommend giving Verizon a call. They may be able to reactivate it. I did notice that the problem persisted even though I flashed a couple different roms on the device. I'm thinking it probably isn't a great idea to remove and insert the SIM if you don't have to.
Just an update,
I spent 2.5 hours at the effing verizon store today after spending an hour on the phone. Even after all that time, and giving me a new SIM, they STILL couldn't get my TB to connect to 3g. They said that it might magically start working at midnight for no particular reason, but had no clue what to do (I was actually at a corporate store btw) If it doesnt start working tonight, I am going back tomorrow. I have no idea what the hell is up. I am very tech savvy, and this is just insane. It must be a verizon problem in my area that it wont let the phone reactivate for the 3g/4g

[Q] weird boot loop

ok i just got this hting less then a week ago, and 2 nights ago i was loading some game and the thing crashes. no big deal, boot right back up again. unlocked the screen, got to about the point where the sense weather displays and bam reboot. then even if i left it alone, it would constantly reboot. it got so bad to the point i couldnt even get it into h-boot. so i let the battery die, charged it up then booted it into h-boot and did a factory reset. reset worked fine, got 70% of the way through set-up then bam, boot loop
let the battery die again, factory reset it boot i into recoverymode, and was able to reboot and set it up. used it for about 10-20 mins, started syncing up accounts and stuff figuing whatever i did fixed it. bam, reboot. now im at square 1.
now im in my 14 days to exchange it but every damn store in boston is sold out, and since im an employee of at&t it get least priority to inventory(yes even though i am also a paiyng customer, seems kinda stupid but whatever). and i dont wanna deal with somerhing refurbed if i have to do a warranty swap...
so ANY ideas or help would be great.

When you wiped and restarted, did the device begin to restore your installed apps? I would try a wipe without the device restore, just start it clean.

I'm with ya. Mine was solid for the first couple of weeks. Now its just a bootloop. Oddly, it was fine while I was on a flight today. Maybe something to do with the radio??

And FYI I'm on the horn with HTC who says its a problem with the SIM. I took it out and its working just fine on wifi. Of course they have no resolution and offering to do nothing for me, other than "they're looking into it". It did stop the reboots for me though.
Same problem
I have had the same problem. Taking out the sim worked for a day but now it still reboots. Doing a clean factory reset doesn't work. It will re-boot over and over until it runs the battery out.
HTC said they are looking into it. WTF.
I use mine for wifi only, no SIM...I've been stuck in the boot-loop of death 3 times and the only thing I can do is let it run till dead. Really lame...and I was outside my 14 days.
Best build quality of any tablet I've owned (just about all of them) but it really has quite some bugs.
Thought I would share since I feel the HTC rep is full of BS with the SIM solution.

I agree with what you've said and feel that if we can't get some root access and start cleaning this thing up it will not live up to expectations... I'm finding less and less reasons to use it each day.
By the way. back on topic. I've gotten a reboot 4 times today while trying to get the gps to hook up and navigate. and it never has connected!
FYI: They're saying it's location-based now. HTC made me give them all the addresses I was at while it had been rebooting. It's happened to me in Chicago, where I live, and DC over the weekend.
I got this thing for remote administration. It's worthless to me without a SIM card.
AT&T is sending me a free one though. Guess I'll see if it happens on that one.

I just landed in McLean and my device is rebooting like mad unless it's in airplane mode!!!
I've disconnected all mobile data and am connected with wifi only and so far no reboots... Will keep you informed but suggest you attempt same. 2:15pm Still no reboot!! 3:45 turned off airplane mode... rebooted twice already.
10:57pm. No reboots once I got out of DC/McLean area and into Baltimore. Back in Texas now and no reboots since landing and corrected to 4g
My reboot problem solved with workaround - boot in portrait mode
I had what may be a different issue than described in other entries on this thread, but here's my story:
1. Rebooted the device manually (to clear app memory)
2. Touched screen to log in
3. As soon as circle dragged to middle of screen, device reboots
(repeated this many times in frustration, then)
4. pulled SIM Card and microSD card, same issue
5. Put device in portrait mode (HTC logo on right, charger on left)
6. touched screen to log in
7. get to password entry screen.
8. enter password, I'm in!
9. Insert SIM, manually rebooted, log in with Portrait mode, works
10 Insert SD card, manually rebooted, logged in with Portrait mode, works.
11. Manually rebooted, logged in with landscape mode (HTC logo on top, charger on bottom), got instant reboot. Pulled SIM/SD, same thing.
I don't know if it was a bug in the password protection screen or what, but I disabled my password at login and now I only orient it in portrait mode when I boot. Have not had the problem since. Oh and mine is not location-based - It worked forever in Seattle until it stopped working, and also worked in Paris, France until it stopped working. Same location each time - same room even. only change was orientation of the screen for me.
I think all the reboot issues are related to AT&T Sim cards and AT&T apps
Because I unlocked my own and uesing another sim card and I didn't face any rebooting issue

It is entirely location based. Last week I was in McLean VA. My device was in constant reboot. When I left and was closer to Baltimore it was fine. In Austin over the weekend... No problem. This week in Nashville... No reboots at all. I'll be in DC next week and am sure it will reboot.

Hey all,
This request may sound odd, but could you list out the last time ur device rebooted and in what city?
I'm in Dallas and my tablet stopped rebooting over the weekend.

. Things that make you go hum....
I have the same problem !! I return it and I bought other one "Unlocked" I thought that will work, but,, still with same problem
i will change the SIM card from at&t to t-mobile hopefully the problem will not occur.
The ones not having or the reboots stopping, are you in a LTE market? Plus you could be a “soft” LTE market. ATT Intruder, Austin is not listed as a LTE market, but does your JS indicate LTE on the taskbar? San Antonio had LTE On since Feb/March. The people having the reboots, might be in markets where they are “lighting up” LTE in beta and those APNs/PSIDs might not be load in those new LTE SIMs cards.
Or, I could’ve been out of the cellular world too long…

Reboot issue - just surfaced AFTER ACTIVATING THE PHONE (livid right now).

I pre-ordered this phone and received it on 5/24 - I've been using it around the house on Wi-Fi to check email/internet, etc but waited until last night to activate the phone.
Now, I'm having issues with the phone randomly freezing and rebooting. I've done numerous PRL updates, I'm going to try a hard reset now too.
What's interesting is that this happened ONLY after I put the phone on the Sprint network. The phone has been in use since I got it on 5/24 and I never experienced this issue. In fact the problem started as I was trying to activate the phone. The phone froze while trying to use the "Activate this device" feature in settings. I had to turn around and go online to activate it.
This sounds like a network/software issue - why would this problem surface immediately after activating the phone???? Grrrr Sprint.
I had problems using the activate this device in settings as well. It would not activate and kept retrying to activate every minute or so. I ended up calling Sprint and they had me do a PRL update. I can't remember though if they did anything on their end. In the end it worked after the update. Maybe give them a call.

I was able to activate phone on Sprint.com.
Did or do you have issues with the phone freezing after activating it?
if you're gonna hard reset your phone, I'm pretty sure you need to wipe data for Google wallet first. Good luck. Sorry about reboots. Never had one on this device.

I had small problems activating also so I had to call sprint. They had me go to settings>system updates>update profile and then everything was fine. You might want to try that too.
Sent from my EVO using XDA
You could see if calling Sprint and having them re-provision the phone.. not sure if it will do anything but it doesn't hurt and takes a few minutes
Thanks for the suggestions guys - ultimately I decided to exchange the phone.
I pre-ordered the original phone and you know the first batch are always a little buggy. I was able to duplicate the problem immediately at the Sprint store just by turning on 3G, lol. It froze and went into its reboot cycle.
So far the replacement seems ok.......

Verizon LG G3 Phone not registered + IMEI all zeroes

I just downgraded my Verizon LG G3 down to 10b from 12 and rooted it, did supersu and flashed TWRP and all is fine there. I then checked off Survival mode in supersu as well. When I went to my update section in settings I got the message that my phone is not yet registered. Now I did read those other threads that explain that when using a flash tool you need to pull out the Sim card, which I didn't do nor did any one of the guides that showed me what to do say anything about that step. So is the fix going to Verizon and buying another Sim card and then inserting it and doing a factory reset? Will I lose root if I do this? Is that basically what I do? Turn the power off, remove the old Sim replace it with the new one turn the phone back on go to settings and do a factory reset? Will the Sim activate that way or do I need to let Verizon themselves do this for me? How does the new Sim get reactivated for my account?
EDIT
And now I am noticing I am getting downgraded to 1X instead of 4G about a half hour after I reboot, happens every time. I assume that is due to the Sim card issue as well
EDIT #2 Damn now I notice my IMEI number is 0000 0000 0000 0000
Damn I guess I am screwed, thought I would have some answers by now lol. I regret rooting the phone....
Has this not happened to anyone else? Losing the IMEI number but the phone still works? The only major issue I seem to have is I can't use OTA to get back to build 12 because I get that message saying the phone is not registered yet and also about 20 minutes after starting the phone I all of a sudden lose 4G and it goes to 1X. I reboot it goes back to 4G and 20 minutes later back to 1X. I am hoping the not registered yet message is due to maybe a screwed up sim card and hopefully the 4G issue as well. If anyone has any ideas at all please reply. Also will reflashing the phone rebuild that efs partition that stores the IMEI number? As I am under the impression that totally reflashing back to stock rebuilds all the phones partitions.
HERE IS ANOTHER CLUE
When I go into settings in 1X mode, if I turn airplane mode on and then off again a few seconds later I go back into 4G mode for a short while then it goes back to 1X. I am really hoping my sim card is to blame for this issue as I will get a new one today to test it out.
Do some research and look at the G2 method to restore IMEI. Use the hints of how to downgrade version by tot method in connecting G3. It can be done. Try to stay off of Verizon in mean time.

Check this thread for your IMEI issue...it may work for you too: http://forum.xda-developers.com/ver...-t3033445/post58915450?nocache=1#post58915450
Good luck
Thanks a lot for the help guys. I was at work all day so I didn't see that 2nd link or I would have tried it before I did what I actually did. I went to the local Verizon store and told the salesman that in trying to get my phone to be able to use a PS3 controller (which is the truth) me and my buddy downloaded software onto the phone to alter it so it would allow for the controller to work with the phone so I could play games with it. Again all true I just left out the name of the software and I handed the guy the phone after telling him how my Sim card seems to be whacked out and my IMEI is gone. He changed out the Sim card and that did indeed fix the phone not registered issue and also the 4G problem was gone too. I was going to leave well enough alone when he said while your phone will work fine it is showing up as an unsupported device on my computer, it is still within the 14 day exchange period do you want me to swap it out with a new phone? I said that we altered the phone, wouldn't I have to pay for a new phone as that voids my warranty no? He said well I see you are eligible for a discount and since you bought this LG G3 near Valentines day I can offer you a free LG G Tab 8.3 tablet, I will knock off the 10 dollars payment per month from another phone that you are owed a discount on and basically all you have to pay for is the 40 dollar activation fee and sign a 2 year contract for the 10 bucks a month that you really won't be paying since I am knocking it off of another phone for you. Do that and I will just wipe this phone again as it works fine and we can easily fix it and I can just set you up here with a replacement and you will be good to go. I couldn't believe it lol. So I walked out of there with a new LG G3 plus a free (not really free since it is 10 bucks a month but he took 10 bucks off of a different phone which would not have happened if I didn't go there today) LG G-tab tablet AND I TOLD THE TRUTH!!!! It probably doesn't hurt that I now have 8 devices attached to my account and send somewhere around 360-400 dollars a month to them lol.
Glad it worked out for you! Yep, I'm sure it doesn't hurt that you're a non-benefiting "shareholder".
I have the VK810.4G (Verizon LG G Pad 8.3) too.
