Galaxy S4 Stock- No Root: Reboots Randomly - Galaxy S 4 Q&A, Help & Troubleshooting

My S4 got random reboots
My S4 is running Lollipop (updated few months ago) stock rom w/o root, and recently I experienced random reboot few time a day, usually when I launch the stock browser / facebook app. The strange thing is that when the phone is restarted, battery drops to few % only.
I've tried to replace a spare battery, the same thing still happen.
Factory reset is the last hope I have, but before I doing this, any other tricks that can help? Battery calibration?
Please help me.......

Battery calibration is a myth and does not exist. Perform a factory reset.

If worried about losing apps, you could root, install titanium backup, backup apps then move/copy titanium backup folder to SD card, factory reset/Odin, root, install titanium backup, copy/move TB folder back to original location then open TB and restore apps, then unroot. Edit: Will void warranty, thanks for correcting me @sutharmukesh88

On 4.4 you could at least, my bad. I thought you could use those one-click apps like kingroot as long as you didn't change recovery or anything, guess not?

best way to backup before factory reset

Hey there, i have my phone rooted, i have installed the OTA update, and i have slowly removed some bloat through titanium backup.
i am still experiencing quite a bit of lag, and want to factory reset my phone, then see if that helps. i want all my data to stay though, can i just back it all up through keis? or is there an easier way?

I personally use Titanium Backup Pro (if you haven't bought Pro yet, it's totally worth it - it has saved my @$$ countless times!). I Haven't actually uninstalled any bloatware, but frozen plenty of it. This made it really, really easy to get the OTA installed - all I had to do was unfreeze the 3 magic APKs that let me install the OTA, and even kept the rest frozen. Re-froze when done with OTA.
I have two sets of Titanium Backup backups right now:
- A backup of all system apps plus data. I would never want to restore my system apps, unless I get bored and start modding stuff later. I figured I'd just snag a backup NOW in case it ever comes down to that - I'd be able to theoretically restore a single broken APK, or manually extract the apks out of the backup files later.
- A backup of all my user apps plus data. Be careful not to ever restore system app backups, even the "green" or "yellow" ones in TiBu. Rarely, you can get away with restoring these (like SMS, or WiFi access points, or sometimes even the System Settings), but it's usually asking for trouble. If you're going from the same ROM to the same ROM without any version change, it's usually "okay" to try. Otherwise, use extreme discretion and be prepared for weird behavior.
So to answer your question, I would recommend using Titanium Backup Pro to keep data backed up. If you're thorough and have the patience, you can effectively backup all of your data, individually, for all of your apps and your system settings. I'm actually planning on doing a data wipe for good measure (haven't done so yet since I got the OTA), and this is how I plan to restore all my data and settings.

Any problems moving to 4.3 after restoring apps and settings w/Titanium Backup Pro?

I'm thinking about finally moving to 4.3 using a custom ROM (haven't decided which one yet). I have Titanium Backup Pro and plan to restore all my apps and settings after the upgrade. Is this process likely to end in a stable system? I don't have the time and patience to go through installing and configuring everything again, so if it's not a dependable process I might as well wait for the OTA update (and deal with Knox later...)
Thanks!
Don't worry, this is what I did all is fine.
Before anything, make a backup of your internal SD (just in case), EFS backup and all apps with Titanium. Then in Phils recovery select option to erase everything for new ROM flashing. I also did manual wipe of cache & dalvik just in case. Don't worry, your internal card won't be touched, but always better safe than sorry. Then flash MJ5 kernel, and finaly flash your chosen ROM. Then you can restore apps from titanium. I had like 2 apps that didn't work at all after restore, probably incompatible with 4.3. The system is stable 100%. Never had a reboot.
Thank you Dalanik. This is very encouraging to know.

Did you try it? How did it go?
I had faced a lot of issues when I did this recently. My contacts and message apps started to crash. Could have been OS problem no idea, but I was losing all my messages and my contacts. Ended up using super backup and import/export feature. Then on TB i restored only the apps and not the settings or system data. Now its perfectly stable, no crashes whatsoever
If you erase phone completely for flashing, contacts will be restored automaticaly from google contacts, but I'm afraid SMSes won't. That's another thing worth backing up. I used SMS BAckup and Restore, works perfectly, although you can also use Titanium as well.

HELP! - Titanium backup Killed GPS and a few settings.

I have a Note 3 running stock 4.4.2. I rooted successfully using the towel root method as shown here.. http://forum.xda-developers.com/galaxy-note-3/general/root-root-xxufnf4-stock-firmware-knox-t2840150. I installed SuperSU and Titanium Backup (the non-pro version) from Google Play.
I used the phone and all the features for three days. However yesterday I ran a backup for the first time using Titanium backup ( all settings and apps) and since then my GPS seems to have conked off.... it keeps hunting and does not get a lock. I have tried rebooting multiple times, tried using it with both with Google Maps and Sygic (paid version) but both dont get a GPS lock. I was using the GPS successfully till then, so I have to assume the Titanium backup process must have messed something up . Additionally, immediately after the back up process was over, I found a lot of my setting were gone. I lost the wall paper I had set (reverted to a blank one), keyboard reverted to default Samsung keyboard from Swype, etc. This further reinforces my feeling the backup process mucked something up.
I am sure this is not normal. While the other settings was able to change manually, I cannot do without GPS. Pls help!

Not sure what your level of expertise is, but simplest would be to run a Nandroid backup to your extSDCard, then reflash the ROM. You will then need to re-root etc. One thing to be aware of - when going to Download Mode, ALWAYS power off, remove the battery for 10 secs or so, insert it and hold down the keys to get into DL mode.
Once the firmware is installed & you've got root, you can Restore the Data from your nandroid and be back where you were.
I don't know how running a backup could do anything like you describe - maybe a Restore might do something, but I've been using TB for a couple of years with nothing like that.

I am an absolute newbie wrt flashing etc. I am a sales guy - so my computer knowledge is layman-ish. I can follow instructions though! This is the first time i am trying something with an Android phone - my earlier trysts were limited to unlocking my iPhone 2 some 7 years back!
1. I used this method of rooting since it does not trigger knox. I will look up Nandriod backup - any links you can point me to will help. Only worry is does Nandriod trigger knox?
2. The towel root method only needed me to flash back the kernel related to my ROM (GNJ1) . Do you think reflashing that kernel again will do or do I have to flash the whole ROM again?
3. Do I have to unroot etc before I flash the ROM?
4. Lastly - Do I use KIES 3 to reflash the ROM? (to keep the warranty etc intact)

Nandroid has to do with the Recovery you install. TBH I don't know if installing a custom recovery like TWRP will actually trip Knox if you are currently rooted and HAVEN'T tripped it. My bet is it would. If you have all your apps saved in TB, you could use a root browser like ES File Explorer to make sure you have any photos, Media etc. copied to your extSDCard before doing anything else. Shouldn't have to unroot as normally the firmware will flash over the top, then you need to follow the root procedure again - I haven't used Towelroot so maybe ask in that thread?

Installing CWM to create Nandriod hurt phone

Hello
Note 3, AP:N9005XXUENE3, CP:N9005XXEUNE3, CSC:N9005XSAENE1.
Bought it with rooting in mind, and figured they have been around a while so most problems I might encounter would already have been solved.
Rooted it with Odin, no problems.
Installed Root Explorer, Titanium Backup, Xposed and Wanam, Greenify and Adaway.
Tried a few customizations and all was good, spent time with google before doing anything.
When I installed Titanium, backed up everything including system.
Then I decided I needed a Nandroid backup before i did anything silly.
So I've gone with CWM, and after checking on a couple of sites, used 6.0.4.7.tar.
Installed using Odin, no problems, made a backup straight away.
After reboot all seemed ok until . . .lol.
First thing I found was gallery was not able to show pictures, found them in Root Explorer and they opened ok.
Then opened Titanium where the backup was and it just stuck on 'processing app data' , after I granted su permission.
Had to restart phone to stop it, tried reinstall , same thing.
Tried to use the Nandroid backup to recover , but same issues.
Guess I did something wrong.
Any ideas much appreciated.
Thanks

Twrp is recommended as it's in active development.

N910G boot loop

First thread here
I used cf auto root specifically for my device from the autoroot chainfire website just to delete bloatware like galaxy apps, S health. I didn't delete Touchwiz
Everything was fine and dandy for a few days until my phone starts crashing when browsing youtube, facebook etc.
recovery screen said it was due to 'dm-verity verification failed'
Browsing the forums, apparently flashing it with the stock rom should solve the issue. It didn't though
I flashed it and rooted it again and the problems persist
I'm lucky I backed up my data. It's just annoying having to restore everything once my phone boot loops.
What seems to cause it?
Because it's not clear from your thread, I've got a question:
After you flashed the ROM and rooted it again, did you remove the bloatware again, just as before?

So the problem is caused by removing the bloatware. Because of the programming of the bloatware and the ROM itself (they are kinda "linked" to each other), it can brake your system, just as in your case.
How did you remove the bloatware? Did you use an app? Maybe we can find a way removing it without killing your system.

I used titanium backup to delete it
Update
Bloatware doesn't matter now though
I reflashed my phone with stock rom again, this time without rooting. My phone still suffered from boot loops. What's happening here? Do I have to do a factory reset?

Did you flash the proper stock ROM for you device? Where did you get it from? I guess that something went wrong while flashing. A factory reset could solve it, but flashing the stock ROM should have resolved the issue already if the bootloop was caused by removing the bloatware - that's what surprises me.

Hi sorry for necroing and leaving a late reply
I used the Singapore starhub android 6.0.1 rom the device came with
I reflashed it and did a factory reset 3 weeks ago
Replaced battery as well
Worked fine for the time being
Then out of a sudden a boot loop occurred while I was on data
What's the cause of this?
I'm frankly tired of having to reflash the rom over and over again as well as restoring backups
I'd go for a full, clean install of stock (format /data from TWRP. Yes, a full format! Make sure you backup your media as this will erase absolutely everything.) and then flash stock with Odin.
Test it out see if it still has problems or if it's stable.
DO NOT RESTORE APPS FROM TITANIUM BACKUP
Re-download them from scratch.
I've noticed that I used to get random re-boots after restoring backed up apps from Titanium Backup.
Went ahead and started the phone over from absolute 0 and it seems my problem went away.
