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
Help! My phone is freezing / locking up and rebooting several times a day now!
I successfully did the stock AT&T Jellybean update this week when it became available via Kies.
I had no issues with the initial upgrade…it seemed to go smooth.
After a day…or a few hours….I can’t remember…I did start noticing a few issues with Touch Wiz closing or freezing and some other apps misbehaving. I can’t even remember what exactly the issues were.
I was also having some other quirky issues with the phone on stock ICS before the JB update…so I have been meaning to do a factory reset and reinstall everything.
So with the phone being even more flakey with JB I went ahead and did a factory reset with my new JB setup.
After a few hours setting up the phone with all my apps, settings, etc I noticed two issues. Swiftkey would not remain selected as my default keyboard and AT&T Voicemail viewer would not retain any of my account settings after a reboot.
After some Googling I learned that this is a know issue with JB 4.1.1 for many apps…they don’t quite install properly and something happens during shutdown that causes the settings to be lost. The only work around seemed to be:
Root Phone
Install apps
Backup with Titanium or other backup program
Uninstall apps
Restore apps – then they somehow install properly and work
I did this…first time rooting the phone….and the root and work around worked perfectly first time.
But after continuing to install apps and tweak my phone the real problems have now begun.
The phone is completely freezing at random times…in any app or in the TW launcher. It seems to just sit there frozen until I hold down the power key long enough to force a reboot or take out the battery.
There are no force closes or other error messages and I have found no other pattern to the freezes.
So now the phone is almost totally useless. It may work for a few hours…or just a few minutes before locking up. Worse…I have no way to know this has happened if the phone is in my pocket.
I did another full factory reset using the Recovery Mode and reinstalled everything again and am having the same issues.
I fear the root somehow corrupted my phone or one of my apps is totally incompatible with JB but I have to many (~70) it will be very hard to tell which one.
The other issue I am having is the battery is draining in just 4-5 hours even with light use.
Coincidentally….4G LTE was just turned on in my area this week so that would be a factor in both the battery drain and maybe even the lockups. I have a Microcell at home…wondering if 4G LTE and my Microcell are not behaving.
There are just too many variables with a new ROM (JB), fresh rooting of the phone plus recovery app installed, plus 70+ apps, plus new 4G LTE, plus my Microcell.
I don’t know what to try next to get the phone stable or to get the battery use reasonable.
Please post any and all suggestions….
One thing I’d like to clear up or eliminate is the root issue…is there any way that is the cause of my phone’s current problems?
What a mess of a week! Instead of the total awesomeness of JB, 4G LTE, and the fresh experience of using a rooted phone...all happening for me in the same week...I get a total headache and useless phone. Sure hope I can dig my way out of this.
Thanks for reading my long post!
I'd say to flash stock rooted official jellybean from here http://forum.xda-developers.com/showthread.php?t=1968625 i'd then do a Hard Factory reset *2767*3855# then you can install apps that are compatible with jb but not the app data and see how the phone is. also, for signal issues, try using a different modem located herehttp://forum.xda-developers.com/showthread.php?t=1831898

Thanks for the ideas....had not heard of the "Hard Factory reset *2767*3855#"....how is that different from a factory restet initiated from winthing Android or from the recovery program?
Also - is there any quick / easy way to know which of my apps are supposed to be compatible with JB?
Sure will be a pain to reconfigure everything again.
Should I be safe installing my apps via Titanium backup restores? (as long as I don't restore data)
Also - what about restoring my IMs and call logs from Kies? Is that safe?

Do you happen to have juice defender? I had the same problem, and noticed it only happened when I was on battery. I uninstalled that and it stopped rebooting.

Nope....juice defender...
And my phone doesn't really seem to be rebooting....just freezing up. I have to force it to reboot by holding down the power button for 10 seconds.
About to try a fresh factory ROM install (pre-rooted) and a hard factory reset.
Then I'll add my apps back very slowly to see....
What a pain in the you know what!

Well...I did all that...and no luck. Still freezing up.
I could not actually do the exact *2767*3855# reset...the phone would not respond to that command. So I used CWM to format the SDCard and also did a factory reset there.
Reinstalled my apps carefully and without data restore...boom....phone is locking up all the time again after maybe 12 hours of good operation.
Either this build of JB is not working on my phone or it somehow got fubar'ed during that first upgrade.
My plan now is to restore to factory ICS un-rooted....reset the flash counter if possible....and return the phone under warranty if possible.
Any recommendations for this?

HELP!!!! Please!!!!!
I did a warranty RMA and got a new (refurbed) phone from AT&T. I set it up with stock ICS and it seemed to work fine. I installed CWM without rooting via ODIN and did a Nandroid backup. I then used CWM to load TWRP recovery and did a backup with that.
Then I loaded the stock JB room with root. Tweaked the phone and app settings a little and things seemed to be fine for 1/2 a day. I reinstalled TWRP since the ROM flash replaced it with stock recovery. Things still seemed fine.
So...with JB rooted and seeming to work fine....I booted into Recovery (TWRP) and did a fresh Nandroid backup since the phone was finally all configured and working (apparently).
Well after rebooting from the backup...the phone is acting all crazy again. It seemed to crash my home WiFi network....had to reboot my router. Now the phone freezes or locks up any time I disable WiFi or change WiFi settings.
I am just cursed with the GS3!
Two separate phones with stock AT&T JB with root...one running CWM Touch and the new one running TWRP and both lock up or freeze all the time.
Should I give up and try custom ROMs? Give up on rooting?
I want TouchWiz for SBeam and some of the Samsung apps that I like better than stock...would rather just stay stock with Root.
What can I do to get this phone stabilized with root and JB???
Just did another test...
If I leave my house and walk a couple hundred yards away...as soon as the phone finally loses the WiFi signal and disconnects it locks up.
Seems like all my issues (with first phone maybe too) are tied to WiFi.
Is no one else having WiFi issues with JB? Could it be tied to rooting somehow? For instance...maybe the stock rooted ROM has different modem or WiFi drivers...or different kernel than the actual stock JB ROM I first used via Kies update?

I've got the KIES JB Update, & rooted. I am not experiencing any of the issues your having. It might be helpful if you could post a list of apps & widgets that you have installed, If you have frozen or removed stock files.
It sounds like you may be experiencing some app conflict issues.

Having the exact same problems as you. Please help. I'm also considering giving the phone back at Best Buy and having them give me a new one with ICS and leaving ICS on there. My steps are very simple. I had the stock ICS ROM from AT&T and I used Kies to upgrade to stock JB. That's it, nothing else, no rooting, nothing.
I am seeing exactly the same behavior, when wifi switches to 4G or even sometimes when bluetooth comes on, etc I will see the lockup and hang. Have to hold down power button to restart. But I don't think this is completely the issue, because even if I turn off wifi, bluetooth and only leave on 4G, then I still will see random reboots, but a lot lot less frequent. Also, I have always had 4G and I see the battery only lasting 4-6 hrs, so I think this is normal with 4G. I saw this even with ICS.
I have not done any factory reset or anything - I would assume if you use the Kies s/w to update and it leaves your files and apps on there, then it should just work. But I will try the factory reset once I backup my contacts, etc.
I'm a little shocked that people are having this problem with a newly released ROM.

After several re-flashes to stock JB with root and still more freezing with WiFi, etc....I gave up and loaded a custom ROM this morning.
I'm running BlackJelly...and after about 8 hours it seems be be running great so far. It is TW JB-based...and having very few issues with it. Battery is poor but it takes a few days of charging and use I guess to get the battery / phone / ROM calibrated. AT&T Visual Voicemail is not working and the phone shows H instead of 4G LTE...but I'm sure I can fix those issues by searching through the hundreds of thread pages on that ROM is this forum.
Give it a try before you switch to ICS or trade in the phone. You can always flash back to stock un-rooted and use Triangle Away to reset flash counter.
Good luck!
Still stuck with crashing phone!

Well...after over a week of trying it out....BlackJelly did not help me. Still had freezes / lock-ups.
I can't tell if the phone is re-booting itself or just re-launching the Launcher (I us Nova but tried stock and Apex too). The phone appears to re-boot on it's own but the up-time under status would not reset...making it seem like not a re-boot but a launcher reload or something. Pretty much same issues as with stock JB.
So I gave up and tried CM10.1 nightlies....and wow....crashing all the time now. Whereas stock JB and BlackJelly seemed to crash when I left my home or left any WiFi network or even just when I disabled WiFi while connected....CM10.1 crashes all the time while at home seemingly at random. I can get 5 hours of great use...then have it crash 5 times in an hour. Seems to crash a lot in the settings menus.
This is with my second (replacement) phone. I am just cursed!
How do I effectively use a LogCat app or something to find out what apps or services or whatever are crashing my phone? Help!
Read through this whole thread and no where did you ever mention clearing your cache. Clear your system cache/davlik cache and reboot.

Sorry...should have mentioned that. I've cleared the system and davlik cache many times...before and after flashing. I've done full system wipes / resets, formatted my SD card...everything I can think of.
I either have a rouge app that I seem to install right away after clean flashes....or a rouge Wifi router in my house that messes up my phone even when I leave and use other networks...or a rouge ATT&T microcell that does the same....or a rogue LTE area in West Michigan....
Or a second bad phone sent from AT&T. But no form of JB seems to work for me no matter what. Guess I could run a clean install with no apps for several days...and then add in an app a day for the next 2+ months until I find the bad app...if that is even the case.
So bummed with this mess!

Interesting....that might be what I was experiencing....but I never thought that was it....did not notice that cause/effect.
I gave up and went back to stock / rooted ICS / TW...version LH9. Loaded it yesterday and have had 24 hours of great use...no issues.
I miss JB and Google Now...but at least my phone works!
I'm not sure for stock JB but on other ROMs, you could try changing your governor and scheduler.

When on CM10.1 I tried bumping the minimum CPU speed to 484 and 5xx (can't remember the actual numbers)....and the maximum CPU speed to to 14xx and 13xx (again, can't remember)....and this did not help.
Not sure if that is what you meant tho.
Anyway...I gave up and went back to rooted stock ICS (LH9) and the phone is working great. I've given up on JB for now. I will wait for a new major JB release from Samsung before I try again.

Q: The phone keeps freezing when I go into landscape mode.
A: This has been covered many times in the thread, but to reiterate: If you are using the AOSP lockscreen you must disable "Ripple Effect" in Settings -> Lock Screen -> Lock Screen Options
Ok, I'm at a total loss. For some reason my gnex running liquidsmooth started rebooting randomly today. I tried wiping cache/dalvik and that didn't work, so I did a factory reset. That also didn't help, as soon I was asked to choose a wifi network the phone froze and rebooted. So I tried restoring to a previous working version of liquid. I still had the same problem. It rebooted every 5 minutes! Then, I tried wiping everything and installing a fresh copy of liquid,but I still couldn't get past choosing my wifi network w/o a reboot. So I finally tried restoring to a really old aokp backup and it STILL is rebooting. what the heck is going on? Can anybody give me any help? Is this a hardware issue? I've also tried two different batteries by the way.
Some more info. It seems to be tied to notifications. I got it running on the AOKP rom on airplane mod, but when i received a text from my wife it rebooted 3 times. I only got it to stop by putting it back into airplane mod. Could it be a radio issue? I'll try flashing some.
why dont you flash back to stock and see if that works fine. that will tell you everything.

Good point. I'll probably try flashing muzzy's rom really quick, since it's supposed to be so stable to see if that does the trick. If not I'll try going back to stock. I've never had to go back to stock with this phone, so I wouldn't mind avoiding it if I can, but anything is worth a shot at this point.
I really just need to nurse it along until the VZW one or Moto X come out. I'm holding out for those at this point.
I wouldn't recommend flashing another custom ROM. You should flash the factory images.
Hello, all. Long time Android user here, no stranger to rooting, ROMing, all that good stuff. I ran into sort of a weird issue that just started to happen quite consistently over the past few days. It all started when I tried to flash the new XtraSmooth Factory Image ROM when it went up. Everything went smooth, except, for some reason, it kills my data connection. FYI, I'm on Sprint, but I don't think that has anything to do with the issue. But it gets weirder. Even if I try to flash a different ROM, a ROM where I had data working before, data is still mucked. No connection whatsoever. If I try to restore a nandroid backup, even weirder things happen. Like for instance, the restoration process stopping at 20-25% and automatically rebooting back into Android (Which just happened an hour ago), or the backup going into a bootloop. Only solution to these problems are going back to stock and re-rooting everything all over again. It's really weird. Am I alone with this issue? Thanks for any help.
Yes your alone sadly. Restore to stock and root again/unlock bootloader, etc
DON'T PANIC!
I own two Verizon note 4 devices. You could call me a flash-a-holic. I love this stuff and really love my Note 4. It's the best phone I've ever seen with great features that many newer ones do not have. However, you already know that ... so I'll dispense with the speech. Before any of you think I'm new to this stuff, I should say I've been flashing devices since 2005 with my old Windows Mobile devices. I also manage a total of seven Note 4 devices from Verizon, five of which are on my own plan. My neighbor has the other two because they loved mine so much.
Recently, I've been playing around with some of the International ROMS, particularly the Note 7 and S8 ports in the Snapdragon section. I really love those for the scrolling snapshots and S8 launcher (even though I use Nova on my daily device). However, after flashing so many of those and having to use a variety of data fixes to get 4G working, I seemed to have messed up my device. I was having really odd issues, like going from 1X, 3G, 4G, to disabled for several minutes before it would settle and finally connect. I also had issues with text messaging. It would work fine, for a while. Then it stopped receiving messages, but I could still send. I messed with APN settings, which didn't help. I flashed more data fixes and APN fixes I found. Nothing really fixed it. So I figured it was the SIM card. I went to Verizon and admitted it was a custom ROM, but he could see that obviously. He gave me a new SIM card, yet I still had the same trouble. After a reboot, it wouldn't settle on a connection for about three minutes, sometimes more. I still was unable to receive text messages (including MMS) on that device. Even a Nandroid backup did not fix the problem.
Here's what I did to fix it.
I decided it was probably best for me to restore back to stock and go through the rooting process again. Ugh... but I love my phones. I'd do anything to keep them going. Instead of using ODIN to restore back to the original stock, I used the Safe Upgrade for 6.0.1 found below. It's been fixed so it does not lock the bootloader again, but restores everything else to stock, but you get to keep TWRP recovery.

I let it boot and go through the process (without signing into anything). Immediately, I realized that my data/4G problems went away. It never flickered even once. I let it sit for 15 minutes once it finished it's initial setup and rebooted back into RECOVERY to flash Kevin's Flashpoint kernel. That gave me root again with Magisk. After a full reboot, I then went into DOWNLOAD MODE and flashed the newest modem (CQI2) using ODIN. Then it was time to settle on a ROM for my use. This time I decided to go back to another International ROM and it appears I'm good to go. Just remember, the Verizon Voicemail app won't be included and usually won't work with an International ROM. I've tried and only was able to get it to work on one of them. It runs, but just will not connect to Verizon properly to access your voicemail. I'd love to find a real fix for that.
Ah... it's good to be working again. Now I can use Titanium Backup to restore my apps and data. BUT I DO NOT RECOMMEND RESTORING SYSTEM DATA. It can only cause problems.
Just a few suggestions for anyone having issues. ALWAYS keep several files on your PC/Device for this type of recovery.
1. Keep the Safe Upgrade to Marshmallow 6.0.1. image. It will be your lifesaver in case something goes wrong.
2. Keep a good working kernel (of your choosing). I prefer @kevintm78 Flashpoint Kernel. It restores Magisk v14 and almost always passes SafetyNet. I keep both stock and port versions on hand (just in case).
3. Keep a good ROM or two (also of your choosing) in order to reinstall a ROM you prefer to use.
4. Keep a working data fix to flash if you're using one of the ported ROMs. Not all are created equal, nor the same at all. Not all of them work. I recommend the Aurora N7 Data fix (Alpha 5 for my N910V): https://forum.xda-developers.com/showpost.php?p=69066109&postcount=2681
5. Keep the latest version of ODIN around. You'll need it from time to time.
Last but not least ... try this fix before you start blowing up the forums with questions and complaints about problems you have. I've found that most of the odd problems people experience are caused by using Titanium Backup to restore system settings created from another ROM, or trying to add different mods, which cause issues. Don't blame the developer for issues that you have that no one else has reported. Most likely, it has nothing to do with their software. It's probably something you installed or restored from a previous backup. You can let those old text messages and phone history go.
If you use Titanium Backup, only store system data IF you are using the exact same ROM as before. Otherwise you will experience problems.
I was sure my Note 4 was ready for disposal after the cellular issues I was experiencing. However I'm happy to report it's good as gold now. I'm not sure how much longer these devices will work for us, but I'll never freely get rid of mine. Besides, who else can fix the TV in the bar when the bartender loses the remote? Not very many devices these days have IR Blasters installed. I've used mine at least a hundred times for that very reason. But that's only one reason for loving this device. I could go on, but you already know that Samsung made the best device with the Note 4 models.
I hope this info helps anyone having problems after flashing so many different ROMs. I know, it's hard to settle on only one. Happy flashing and remember ... DON'T PANIC!
