[Q] Galaxy S4 restarts every 10 minutes

Well for starters, high everyone!
I have an issue with my S4 and I've searched all over but none of what has been recommended helps.
The issue I have is that my phone will restart about every 10 minutes (give or take). I used Reboot Logger to determine this. The phone only restarts when it is idle. It WILL NOT restart if I am using it (screen is on). The weird part is that it doesn't even go through the whole reboot sequence. The screen will stay black the entire time. The notification button pulses and the home buttons will light up like it was restarting though.
I had a bad battery and had it replaced with a stock Samsung battery. I've tried pulling the SD card, pulling the battery for 10 minutes, pulling the battery while the phone is on, and I've performed two factory resets.
The one thing I have noticed is that, after performing the factory reset, I get an "error" under the little android dude. This also happens if I do a cache wipe.
My model is the SPH-L720 running on android v4.3. The phone has never been rooted and there are no software or firmware updates that are found.
I was beginning to think that this was a hardware issue but the consistency in reboot intervals makes me believe otherwise. At this point I'm at a loss. I rooted my old phone but my experience in that area is very limited. I have read that the cache partition is bad from the factory on some of these (hence the error message) so I was thinking about rooting the phone and trying to use a good cache partition, but that's the only other option I could think of.

sounds like a voltage prob....or mem prob... id redownload a new rom..wipe wipe wipe..reinstall and that should fix it

Insufficient voltage at idle was my first thought too, but if you haven't undervolted (since you aren't even rooted), that seems less likely. If I were you, I'd root the phone so I could do more to figure things out. Maybe try bumping up the voltage a little on the lower clock speeds.

Ok, first of all, do not root your phone. As you admitted yourself, you have limited experience in this area, and there is nothing that rooting will do for you. Not to mention, if you think you have a bad cache partition, you don't need root to fix it. Your phone is stock, running the stock kernel, there is no reason to suspect voltage issues that are not hardware related. If you root the phone, you will likely trip KNOX, and void your warranty.
My personal opinion is that your phone has a hardware problem. If you want to truly start over, either recover your phone through KIES, or better yet, download and flash via ODIN a stock MK2 ROM from this forum. Since this is a stock, signed ROM, you will not trip KNOX, and it will rewrite every partition properly on it's own. This is all assuming you don't have a hardware problem. But do not go ahead and try to fix anything yourself besides what I mentioned. You will not succeed, and likely lose your warranty in the process.
Edit: did you buy this phone new or used? If you bought it used, more than likely somebody ruined it for you. And more than likely, you can fix it. If this was a new device, more than likely it will be a warranty issue. That's why you shouldn't do anything to void the warranty.

If you're going to use odin for anything, just make sure you follow someone's directions step by step. Otherwise very bad things can happen.

im also having a slightly similar problem
Problem : The screen after a sleight amount of time of being on, or sometimes instantly when opening the lockscreen it freezes for 10-15 sec then shoots black lines across it, then reboots.
Things ive tried :
1. Installing a new rom ( from AOKP 4.4 and Triforce 4.3)
2. Changing modem (from MJA, MK2, NAE)
3. Changing the type
of Gapps i was using. (4.3 gapps for triforce, aokp 4.4 gapps, and pa gapps)
Current Phone Info:
Rom: aokp_jfltespr_kitkat_nightly_2014-02-08
Modem/Firmware: NAE
Gapps: Pa.gapps 4.4.x
Let me know if you need anything more! plz!

I'll look into Odin before I root. The phone was also purchased new. I spent most of today monkeying around with different settings to see if I could trigger the issue as well. As it turns out, the phone will only restart at idle if it's plugged into the charger, or the wifi is on. If wifi is off and it's not plugged in it's fine. I am also using the stock Samsung charger that came with the phone. Again though, if I'm actively using the phone it doesn't happen (charging or connected to wifi). I did turn the phone off earlier to charge it but would keep freezing at the sprint logo upon boot up. I thought it was bricked for a second... I wiped the cache (didn't do a factory reset) and that fixed it, but now I have that stupid issue where videos won't play on wifi, only on 4G or 3G. It's an issue I thought I had solved.
Le sigh. This is frustrating. The Odin option is looking to be my best bet it seems.

Since you are running a custom source-built ROM, first thing to do would be to ODIN a stock ROM. If the problems go away, you have your answer. If not, this would likely be a warranty issue. Of course you tripped KNOX most likely already.

Alright I'm a little confused as to what exactly I should be using. I found this:
http://forum.xda-developers.com/showthread.php?t=2575470
which is a stock ROM. Although I also found this:
http://forum.xda-developers.com/showthread.php?t=2259513&highlight=odin
which is the stock firmware.
Which one do I use, or do I use both of them?

Follow instructions in the thread. This is a completely stock rom with no root or mods and will not trip the Knox bootloader. If you flash anything other than this, including custom recovery, cf autoroot, etc, you will void your warranty.

i had this problem once and it was related to a corrupt file on my sdcard believe it or not. there are Defraggers out there for your android file system and internal SD card but your Ext sc you would have to do on your PC. it worked for me. the one i used is called CLEAN i got it off amazon app store.

That solved my problem, thank you! I spent the last couple days testing it just to be sure I wouldn't be crying wolf. The phone has yet to restart on me even while charging or using wifi. The error message I would receive after a cache wipe or factory reset went away as well. It makes me wonder if the bad partition was what caused my old battery to fail.

Great, I am glad it worked out, and hopefully your problem is resolved. I doubt that your old battery failed due to a bad partition, and I have to wonder how your partition got messed up in the first place, but that's just a curiosity and is irrelevant in the grand scheme of things. Just remember that if you decide to root, cf_autoroot works but will trip the KNOX bootloader and potentially void your warranty.

[Q] GS5 Sport

Hi, I think that I have done something to my new phone and it is not working right now. I was trying to root it, and followed the directions and it went into the rebooting phase. But now it does not want to get out of the rebooting phase. It keeps on turning off and on. I need help. I have looked all over to see if there is ways to root a gs5 sport and have come across a site that said do not try to root it. Now I am in trouble and would like to fix this problem. How do I factory reset this phone, root it if possible.

If you're stuck in a bootloop, pull the battery and boot to recovery, hold home, vol up and power until it boots to recovery, then select wipe cache then wipe data factory reset.

You can try the advice above, but it may not be sufficient. The poster there isn't very attentive to details.
Your phone is in a bootloop. If you are lucky and it's just due to a minor conflict then the above advice will prevail. But if your root was incomplete or any errors were written then it won't be sufficient. In that case you will need to use Odin to write a full factory firmware image to your phone to revert it to a proper working condition.
You should be able to root your phone. But we need to know the details of both your phone (model, firmware, baseband versions, etc) and a detailed description of how you tried to root it. In particular what file you tried to write and the Odin log that shows if any errors occurred during the root. Without those critical details we don't know what happened. If that information isn't available for some reason, then your best course would be to back up any files that are important to you. Then write a full stock firmware image to your phone and start over.

Phone rebooting randomly

Hi everyone, I'm new to the forum with an account but before today I've always read the forum without an account.
About 1 month ago, I rooted my SM-N9005 (it was GNG1 with Italian Vodafone ROM) then installed Safestrap and then I installed a Custom ROM (Galaxy S5 by IKINDER_BUENO). With the custom rom, the phone had no problems except the initial ones (apps started auto-closing randomly), but after 2 days of use the problem flew away autonomously.
Last wednesday I removed Safestrap and the custom rom flashing the phone with the original nobrand rom (ITV-GNG1), after that my phone started to do the weirdest things (auto-closing apps, very excessive battery drain ecc.), then this morning I turned off the phone due to school things, when I rebooted it hadn't any anomaly, but after 30/40 mins (no use, just in the pocket) it auto-rebooted so I thought that maybe the system crashed or maybe something similar happened, but after it booted correctly, after only 5 min it auto-rebooted 3 times in a row without any user interaction (reboot->boot->30sec ----> reboot->boot->30sec ----> reboot->boot->30sec ----> reboot->boot), it made me worry about that, so as soon as i got home I reflashed it with the original Vodafone ROM, but nothing changed.
Now, my phone reboots randomly and also the proximity sensor doesn't work (probably is a ROM issue, I'm downloading another version of the Vodafone ROM because the one I've downloaded has German Apps, now I'm downloading it with Italian apps (I hope so).
Could someone help me resolving this issue?
I asked also Vodafone support if they could change my phone (they repair only but in case that the phone came back 3 times from SAMSUNG assistance without resolving the problem, they will change it).
Ah, my KNOX Warranty Void is 0x1 due to the root.
Sorry if I've done grammatical errors, I'm Italian.

Install TWRP, flash a custom ROM then wipe data, cache (not internal SD) reboot into the custom ROM, set it up and see what happens after 24 hours. It's possible the device just needs cleaned. You could reflash stock again and do a complete wipe but since you've tripped KNOX to 0x1 already may as well wipe manually via recovery.

Hi man, thank u for your very fast answer, so schematizing the process:
1) Install TWRP through Recovery;
2) Flash a Custom ROM (I will use again S5 Port by IKINDER_BUENO);
3) Wipe data and cache from TWRP, right?
4) Use custom ROM and test if the issue is resolved;
Is it right? Correct me if I'm wrong, I don't want to trip anymore my phone.
In case the issue is solved, and I want to came back to the original Recovery and ROM, how should I do?
Thank u again.

Yip that's correct but install TWRP recovery through ODIN. Once you have tripped KNOX you cannot trip it anymore.
In order to go back to complete stock afterwards, find your firmware for your country and model number. The. Flash via ODIN

Hey man, I've noticed something very unusual... Every time the phone autoreboots battery stats resets, it's very strange.
Have u ever had/read a problem like this?

Hey man, I've tested your method and some issues seems to be resolved (auto-reboot), but other issues are arrived (any sensor isnt working, no one not just the proximity one and sometimes the phone shuts off and wont turn on, and I've to remove and reinsert battery and then then the phone goes).
Waiting your instructions.

Hmm, there was an issue where one ROM killed the sensors on a Note 3, but that was last year.. There is a post somewhere about how to fix them. Can't remember where it was. But, it's possible you may have faulty sensors :crying: . I'll have a look in the morning (just finished work now) -and try and find out where the post is and what the fix was.

Thank you for your interest, I can prove that my sensor aren't fault (I hope so, but 2 weeks ago they were working!)
What about the battery problem?
UPDATE:
Hi again, this morning phone started rebooting autonomously, during 6 hours it rebooted somewhat like 3 o 4 times. Sensors are still dead, none working and as I anticipated yesterday, phone sometimes turns off and wont turn on unless I remove battery.
Now I'm installing Cyanogenmod, and try what happens.

I've also searched for the post of the note 3 with that dead sensors, but I haven't found it.

[Q] Galaxy S4 random rebooting after installing CWM

I hava a Galaxy S4 GT-i9505 and yesterday i rooted it and installed CWM 5.X.X.X
but now it keeps randomly crashing, it happened while browsing, while using snapchat and watching photos but also while just watching home screen.
When it crashes it freezes for a moment and then shows samsung logo and after a while it is back up and shows my unlock screen wich i dont have to fill in my Pincode like i have to do when i reboot or boot my phone manualy.
I have updated CWM to 6.0.4.7 but still it is crashing
I am running stock 4.4.2 android only CWM and SuperSU
I have searched for a similair problem but couldnt find anything

Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck

I also had such an issue. It happened to me only after installing viper4android on the stock rom.
Deleting the app didn't help.
You will probably have to re-flash the stock rom via Odin. Or change to a custom rom..

I did reroot it flashed stock rom still freezing and rebooting.
I just want to keep 4.4.2 wit root access.
Any other way than achieve this beside cwm with SuperSU?

You need to delete Knox. That's the reason you are experiencing reboots. Afer you root you have to delete Knox.
Get the Knox removal script from here and flash it:
http://forum.xda-developers.com/showthread.php?t=2507931
CWM is totally unrelated to your random reboots.

Thank I will try this tomorrow.
Although when I first booted my phone after rooting it asked something about disabling Knox.

Disabling and deleting are two different things

Good to hear that still got hope

I hope you did a full wipe before re-flashing stock rom, right?
Doing a dirty flash will not help you much.

Yes full whipe factory reset dalvik cache data files, all even formatted my SDcard

Root and flashing Odin with my Tab 4

Hello,
I'm new on this forum and rooting is all new to me. Please don't simply delete, at least indicate where I can find my answer.
So I found a CFA that's supposed to come with SuperSU and I flashed it with Odin. The first time, I could boot, but TouchWiz constantly displaying a bug pop-up without letting me access the tablet had me flash the stock firmware back. It was unusable.
I tried again and it worked but my Tab wouldn't boot. After several attempts, I cleared partition and did a factory reset. It seems like I can only boot as in a stock firmware. I had to redo basic questions/settings as if I opened the tablet for the first time, but it doesn't seem like I have access to delete bloatware apps or anything.
1) Did I cancel my CFA flash with the factory reset?
2) I still have stock firmware and do not care about datas or anything since it's an old tablet I don't really use. Is it better to do the factory reset, then try to flash back the CFA file?
3) Did I simply miss something when I flashed and got TouchWiz bugs?
Again, please consider the fact that I'm new and I'm just trying to learn here. I can understand If I have to post this in another category, but XDA seems to be the only place where I can finally get to root, delete unnecessary apps, play with a custom ROM, etc.
