[Q] NO Cell Service/Data before and after unroot. Any ideas? - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

After fumbling around all day I discovered that i basically lost my IMEI and its been corrupted/ set to 0. I have the number from my battery, could someone point in the right direction from here?
Recently, my rooted phone ( I was on clockworkmod recovery and stock rom) became rather volatile and would randomly reboot and get stuck in a bootloop. This lasted about a day and then the phone stabilized on its own and eventually returned to normal. Once it returned, the cell service was spotty and 4G was gone, i only had the occasional E in the top right corner.
This progressively worsened into me having no cell service, however I did not have the circle with the line through it. I had full signal bars all while this was happening.
I decided to unroot my phone and return to stock everything , hoping this would solve the issue. Still nothing.
I did a factory wipe and still nothing. Very rarely ill be able to sneak a text message or two before everything stops working again.
Anyone encounter anything like this before? I'm considering just resetting my flash counter and running over to an AT&T store pretty soon

If you're on 4.3 try flashing this modem here through CWM or TWRP http://forum.xda-developers.com/showpost.php?p=47817339&postcount=23 I had the same problem when I updated to 4.3 and after I flashed the modem I got data 100% working

[Q] I am absolutely stumped, please help

Hi All, I come begging for help after exhausting all of my options and searches for similar issues.
I have a CDMA Galaxy Nexus Stock 4.0.2 but rooted (I installed CWM).
I woke up to my phone stuck in the boot loading screen; it just kept looping over and over. I shut off the phone restarted it and the phone was practically unuseable, it ran very very slow. Now I haven't done anything recently or installed any apps. The only app I installed was a modified MMS app (one of the Inverted Black ones), but that was 2 weeks ago and everything was running fine since then. (However since I'm not on a deodexed Rom, I knew there could be issues).
Well I of course switched back to the stock MMS app that I had manually backed up and that did not help. Now my phone would load, it would get to my homescreen, but it would then say something along, "service is not working, wait, close, or ok?" I'd hit wait and within 2 minutes my phone would automatically reboot and then go into a a sort-of bootloop (it would just show the boot.img and loop).
I then tried to restore two Nandroid back-ups (which were basically bone stock and made months ago) and both worked, except it would say secure.img not found or something like that. I was still able to boot up and use these back ups, but then within 5 minutes I would get the same error and then the phone would reboot.
After retrying them I decided to to just go bone stock and wipe and do a factory reset. This worked and everything seemed fine until I went to turn on wi-fi.
I would wait for wi-fi to turn on and eventually it would just quit and then reboot the phone. I did this 3 times in a row to confirm that it was indeed wi-fi causing these rebooting issues.
Now here's the thing, right now my phone is working as I have purposely tried not to touch the wi-fi (I need to use my phone) . Data, voice, mms/sms all work. But I literally have no idea why wi-fi would be causing my OS to go crazy?
My last resort is to flash the stock toro.img but I was hoping you guys could help me before I get to that point.
As of right now even though I did a data wipe/factory restore my phone is still rooted (rooted apps all work) and my bootloader is still unlocked. (I renamed the secure.bootloader file as per the instructions when using fastboot to load CWM).
Please help me troubleshoot this, Thanks guys.
I don't know if you have tried but maybe try flashing a rom after a data wipe

I'm thinking about doing this as well since I will probably have to flash back to stock. I just want to make sure I can get back to stock since I am still covered by warranty and insurance (assuming they do not check to see if my phone has an unlocked bootloader).

Well you can always relock the bootloader. I doubt you will have to go back to stock though

[Q] Phone deactivated?

I was running latest paranoid android and I wiped cache/dalvic cache after flashing Cerberus in recovery and when the phone booted up it was asking me to Activate (sprint service) my phone. I've never seen this with flashing roms and was wondering if this is a known issue with flashing roms on the S3 or something that can randomly occur from time to time.
Anyone have experience with this before? I had been running Paranoid Android for less than 24 hours but initially didn't have any problems whatsoever.
Itll do that sometimes depending on the rom. Usually does it after a factory reset and installing a cm based rom. Its just asking you to add your google account... you should be fine

This didn't have anything to do with my Google account. I guess I should have been more specific, I mean that my phone is deactivated on Sprint's network as in I can't make phone calls and all the info is missing in about phone. Phone number, PRL and such. I am flashing back to stock right now and hope this fixes it. Will probably give paranoid another go but this doesn't sound like a common issue because I haven't been able to find anything by searching.
When you get back to stock it'll probably reactivate itself. If not (although you can do this regardless just in case), ##72786# in the dialer should set you straight. If I'm not mistaken the screen you're referring to should be gone when you boot stock regardless. Its a bug. Doesn't work for a sprint phone but still buried in the rom
Ahhh... could try manually flashing your modem after the install too

Soon as I flashed the stock rom it tried to activate and initially failed and prompted me to reboot. Second attempt it was successful and then I immediately flashed back to PA and it is working. Going to give it another shot and keep the stock rom on my sd card this time in case I get stuck in a pinch.
I jumped the gun, phone activated fine but signal drops in and out randomly and will not connect to 3g. Just reflashed to stock again and everything seemed fine but signal was still back in and out. Checked under status and PRL read "0" tried updating to no avail so did the dialer code and it did the activation and all is right in the world again, or at least for the moment.
Just trying to figure out why when I flash Paranoid all my settings just disappear
*edit*
Just flashed back to PA this third time after fully making sure that the phone was working and had 3G data and all was right with the world (my phone). Will update if it goes South again but as of right now the phone is behaving properly. Maybe it just wasn't working right the first time and I didn't notice since I was on wifi. Only thing that keeps me from thinking that is I didn't get the Activation message until 12 hours or so after I had flashed and had been using the phone. /shrug
I still think flashing a modem in recovery after installing PA would yield a poisitve result

Thank you,
and sorry if i am breaking forum rules

Having All Sorts of Issues (Won't boot + No Reception)

Hello,
I just got a used SGS II from a reputable dealer. When I turned it on, it was fine, but it was stock. I was getting reception and everything was working as normal. I then used the toolbox application to root and put CWM on it. After I did that, I flashed the Allstar rom. Then all of a sudden I wasn't receiving any kind of signal. Zero bars, unknown, nothing working cellular-wise, anywhere in my town.
So, I think "Maybe it's the ROM' and nope- flashed Corys mod and I'm having the same thing. Everything works 100% fine but no cell at all. So at this point I'm completely stumped, and I decide to revert to stock to see if the bars come back. I flash to stock via Odin, and now it won't get past the "Samsung" screen, after the green android.
Can anyone help? It won't even boot now

Go back into recovery mode and wipe data and cache than reboot!

Try new rom with custom kernel like kko or hotcakes see if it helps with the problem.

To fix the no reception, flash a different radio.
For the phone stuck on the Samsung logo, boot into recovery and do a factory reset.

If you're flashing a JB rom its a known issue that it shows no reception even though you do.

[Q] Stuck on bootloader after changing screen density with Rom Toolbox

Hey guys. As the title suggests, I can't boot my Note 2 (sgh-i317). It is stuck on the AT&T logo and while it's stuck there it vibrates slightly every 5-6 seconds. I tried changing my screen density to 240 and it worked for a bit but annoed me. then I went to change it back and got this problem. I accidentally set it to 360 I think though, instead of 320. I have wiped the cache. I have wiped the data. I have installed roms countless times already with Odin. I'd imagine my reset counter is at over 10 just from today.
I've been searching on google and these forums for hours and have seen many suggestions, but none of them have worked. The farthest I have gotten was to get the phone to boot, but once I start going through all the setup stuff I begin getting error popups saying that Touchwiz home has stopped responding. As soon as I push OK the error immediately pops up again. I seriously can not do anything with my phone.
Is there any way to get a stock build.prop file somewhere for this phone, and if so, how would I install it if I can't even boot into the device?
Any help would greatly be appreciated. I have no idea where else to turn here. Thanks!
-Mark
Do you have a backup to restore from recovery ??
If not....then power down the device and remove the SD card and place it into a PC card adapter...
Then download or copy over a suitable rom...
Then place the SD into the phone and boot into recovery...
Fully wipe the device and flash the rom of choice...
Reboot....set....profit....g
Edit:
Are you certain that your power button is not stuck ?
If the method I suggested fails... and rebooting occurs with vibration...then your power button is suspect....g

Thanks. Well I got it to boot finally, however there's been a couple issues since. It's on 4.1.2 right now...
1. Whenever I try to officially update to 4.3 through the settings, it downloads, then when installing it ALWAYS fails at 25%.
2. This is a big issue. My data connectivity is gone. I have no 4g access period. If I'm not using a wifi network, I can't do anything online, period. I've reflashed numerous times, and can't get it to recognize the network. I can make calls just fine, just no data.
I've tried wiping data and going to factory reset, but this doesn't help in any way whatsoever. I've popped out the battery and sim card and reinserted after a few minutes, still to no avail.
The funny thing also, last night my friend, who has the same phone, updated to 4.3 and got the EXACT issues I've been dealing with. The ONLY thing in common is that we have both rooted our phones in the past. When I first got 4.3 it worked fine. It wasn't until I rooted that these issues began. My friend's phone was not rooted, however it had been in the past. I'm thinking that this 4.3 update has an issue with phones that are rooted or have been at some time. I don't know how it can tell, but that's all I can think of. his phone now is also a doorstop, like mine.
K, fixed data connectivity from another thread here. For some reason, even if I wipe my system, it seems to still keep settings intact. In this case, nothing set in APN. Seems the more I try to fix my phone, the more problems show up.
If you updated to official 4.3...then yes ...a whole new host of problems are yours until the devs figure out the locked bootloader and it's knox flag...
Backups won't restore....and so forth...
Read around ....you'll see...g

Verizon G3 Bootloop

im rooted with no custom recovery on 4.4, i used the phone last week with gps running and mobile hotspot in the sun for over 2 hours and i think my phone got a little too hot. the next morning it started rebooting on its own and hasnt really stopped except for a few hours when it worked on sunday but then started acting up again.
i purchased a new battery and its still happening. id like to try and wipe the phone to see if it helps but i would really like to try and backup my whatsapp database and media and my downloads folder before attempting the restore.
is there any way of getting the files on the phone? i can access download mode and the stock system recovery screens without issue and the phone stays on indefinitely on both of those screens so im hoping that this just may be a software problem.
Any ideas?
anyone?
