[TROUBLESHOOTING] Reboot... Reboot... Reboot... Arghhhhh

I've been having a problem with my phone hot rebooting every 30 seconds to 5 five minutes. It's driving me up the wall. I can barely even use it, since half the time I have no data, and the other half by the time I can get anything open, the phone is rebooting.
I've tried:
- Changing ROMs (Juggernaut 2.5 to 2.6 and back to 2.0; Bombaridier; EagleBlood; Streamlined)
- Changing kernels (stock, Jugs, Bullet, whatever kernels come with the ROMs mentioned above)
- pulling the SD card
- formatting the SD card
- fixing permissions
- factory/data reset, wipe cache, wipe Dalvik every time I flash
One thing I did notice... the last ROM I tried was EagleBlood, and it was fine for half a day. I charged it overnight, and, thinking my problem was solved, I decided to calibrate the battery. After wiping battery stats, it's rebooting over and over again.
I just unrooted and took it back to stock to see if that does anything.
In the meantime, any ideas? Please help... I'm getting ready to tear my hair out.

normally the reboots are due not Wiping, but you did say, you Wiped, so it should be fine
did you OVER Volted the CPU at any point?

No. I overclocked and undervolted when on Juggernaut/Jugs, but at no point did I ever overvolt.

how aggresive were your overclocks. because that could be the problem itself
or if the kernel is undervolted and the cpu's dont like it .

Max 1.89/min 384 and UV -2500 when on Juggernaut, but after I started having the problem, I didn't even install SetCPU anymore. When I was on EagleBlood, it wasn't OCed or UVed at all, didn't have SetCPU installed, and it still rebooted all the time.

OK, I've been unrooted for a couple of hours and no rebooting. But being unrooted sucks! I don't even want to think about re-installing all my apps without Titanium Backup.
So I just Odin flashed CWM and am flashing the SGH-T989 // UVKID // Stock // Deodexed // Rooted //Busybox ROM so I can at least run TB and get all my apps back. Then we'll see what happens.
I'm afraid to calibrate my battery though... Haha... I think the FIRST time I started having this problem was after a battery stats wipe. And then after running EB with no problems for several hours, after wiping battery stats... BOOM! It started happening again. But why would wiping battery stats make this happen?

your using CWM for everything? or RM?

CWM. I've never used RM... Should I?

OK, after restoring everything with Titanium Backup, it's doing it again. So it's gotta be an app... right...? How on earth do I figure out which one?

this is why i never use Titanium backup
your going to have to install each app one at a time to see which is causing conflict

I just have the same problem, keeps rebooting basically every 30 seconds to a minute... and it is not rooted, no new apps but I did update the firmware via Kies in the morning, it only started rebooting in the middle of the night, had to shut it down to be able to sleep.
No idea what to do...
The phone is useless as it is.
Any hints are welcome, thanks.

[Q] Problem with Omega 12 + Perseus 33.3 start up screen lasts forever

HI Guys
I'm an old iOS user but switched to android 2 months ago with a wonderful Note 2 International running android 4.1.1
​
after one month of use I decided to root my device for VPN service and custom ROM benefits
​
Everything went fine. First rooted with odin 3.07, then decided as most of users recommended to flash ARHD 11.2
After using my device for 2 weeks I noticed poorer battery performance. 4 days ago, After a lot of searching online I decided to flash Omega 12 then Perseus 33.3 for better battery performance and better control of my CPU.
That's what I did. First, wiped all data through CWM then installed Omega 12 ---> Perseus 33.3 ---> clean cached data ----> restored my apps through titanium ----> fixed permissions ---> charged my mobile to 100% then wiped battery stats ---> set gpu to 440mhz and cpu scaling --> frequency responsiveness to 600mhz === every thing went very good with wonderful performance and battery life with 40 hours battery life ,more than 7 hours onscreen and also did couple of successful restarts to change SIM card .I thought that's it "I will stick with this system forever no matter what."
:highfive::highfive::highfive::highfive:​
As I said, after 40 hours of battery life my battery died so I put my note 2 with the recharger while off because it was night time. Next morning, I unplugged my phone then turned it on but my startup screen keep showing the big robot walking with no ending for 30 minutes. Tried to restart the phone couple times, searched online for a similar issue but nothing related to omega and Perseus, wiped cache, dalvik but still the same.
:crying::crying::crying::crying:​
Finally, I restored an image through CMV contains my 4.1.1 old stoke ROM + factory kernel just after rooting. My smartphone now is working fine.
My question now is "Why did it happened? Did this happen with anybody before with the same circumstances? and what is the possibility of this happening again if I tried to flash a custom ROM or a new kernel?
I'm ready for any questions​

Firstly, NEVER let you battery die completly, it is not good for the overall life of the battery.
Secondly if that ever happens boot to recovery and clear dalvik cache and fix permissions. This will usually help.
It's hard to say exactly what cause this issue without a log.
Also, please keep regular backups through your preferred recovery, as this will help if you need to go back.
Cheers,
Evil.

Thanks for the tips.... really appreciated

same
same thing happened to me exactly .
same rom same kernel
i couldnt even restore a previous backup of omega from a week ago - it just wouldnt restore without rebooting !!
also, for my note 2 to work again i had to reflash my recovery (twrp) via odin and reinstall my rom.
i had a whole load of other issues and in all honesty im almost thinking i may have a broken NAND chip - sudden death - not quite, but im patched for that, but may be a small fail on the chip had caused this event , i really dont know.
im back to normal now but im stll very worried about the next few days - please read my other post where i explained this fault at the time it happened.
http://forum.xda-developers.com/showthread.php?p=38697185#post38697185
thanks.
.

I will look at it... but I think in the mean time I will stick with my original stock and kernel for a while till I have the courage for another rom/kernel trial

[Q] S4 Mini (I9190) - Strange Battery Problem

I have been using my I9190 for 6 months. Battery life was going down with original stock rom (I9190XXUAMF7).
I have tried all battery optimisation tips and apps. Nothing helped.
Last week i tried Greenify. Made some settings. It was the first time it had 36 hours standby time with medium usage.
Then i have installed newer official rom (I9190XXUBNA1), made all greenify settings and bought new original samsung battery (1900 mAh).
But standby time was (with no usage) 18 - 20 hours. I tried old battery again, it was 16 - 18 hours.
I tried 2 more original samsung battery (19000 mAh). Unfortunately same bad result
I formatted everything again and again. Reinstalled rom. Wipe data cache, wipe dalvic cache, format system - data etc..
recovery-clockwork-6.0.4.6, recovery-clockwork-6.0.3.7-serrano3gxx.tar, philz_touch_6.12.8-serrano3gxx.tar
Odin3 v3.04, Odin3 v3.07, Odin3 v3.09
I formatted external sd card. I removed it...
No improvement...
I do not think that it is a hardware problem. Because - 1 week ago - old dead battery had 36 hours standby time with medium use..
Any recommendation?
Thanks in advanced

New battery require couple of full charge before it can reaches it maximum efficiency. Different type of custom recovery won't change or affect your battery. Optimization and greenify can only do so much as well.
The power heavy drain problem from day one of S4 mini is the kernel's default profile for CPU governor. So, if you want to stay with the TW rom, you may alternatively use a custom kernel: http://forum.xda-developers.com/showthread.php?t=2545244 and change the CPU governor. Any other method is just treating the symptom but not cure the root.
Note if you haven't tripped knox already (if you have knox), flashing a custom kernel will.

Thanks for your message.
I installed the same system, same apps, same optimization methods, greenify with same settings. Everything is same.
My phone was rooted. And it is rooted now, too.
Nothing changed.
I have installed setcpu, one hour ago. I will try it for 24 hours. I hope it will help.
Thanks again

Any other help?

Hi again
I have showed my s4 mini to samsung service.
They told me that there is no hardware problem.
Problem is software.
I have tried two more batteries.
The last one is zero lemon 5100 mAh.
But nothing changes.
I have tried carbon, cm, slimkat, mokee, stock rom, two more roms...
Battery drains too fast.
Sometimes while percentage is 75 %, i restart phone, it becomes 81 % or 69 %
Sometimes while percentage is 75 %, i enter recovery mode, it shows 85 %
Any help please

Have you tried flashing the custom kernel as mentioned before?

Redflag rom has vikinger kernel
It is my current rom

any help?

[Q] Debug Battery Drain - com.android.systemui

Hi,
I'm using s4 mini LTE I9195 with CM11 M6, f4ktion 1.4.0 kernel, BN3 modem, TWRP 2.7 recovery
All was working fine, average battery drain on idle was 1%-2% (not great, but fine), and suddenly it rocketed to drain 15%-30% per hour.
I usually use Android Tuner's battery measure stats to track drain statistics over time.
After checking it, I"ve noticed that it () the drain) started in the middle of the night.
So it's not due to "I launched this App, and then..." It just went nuts on it's own...
I've checked which process is to blame and the first one with max battery consumption is:
com.android.systemui (with KitKat logo) followed by Android System, then Screen, and then all the usuals.
I tried to do reboots, disable wifi/nfc/rotation/data/sync/anything else/kill user apps - no effect ...
It still drains about 20% per hour on system and systemui for the whole day now :crying:
And I have no idea what causing it / how to revert it...
So, do you have any suggestions on how to trace this bug?
What to search for in logs?
Any thing else?
I'm not a big pro on android OS subsystem, so advises are welcomed!

I'd love to help, but I actually stumbled upon this thread while googling to help myself
I'm using Note 2 (N7100), running CM11 - newest nightly (although I flashed it today, after slightly recharging the battery once I noticed the problem) and Devil3 kernel.
I'm having the same issue - yesterday everything was fine, I've left the phone to charge over night and display time as usual and in the morning nothing seemed out of the ordinary, until 6 hours later. After those 6 hours my battery was fully depleted (whereas normally lasts whole day and is not even close to being depleted). com.android.systemui and Android System seem to be the problem for me too.
I've also tried turning off some functions, uninstalling some apps, turning off notification privileges for others. Even, as said earlier, flashed newest nightly. Nothing helped. Using phone with without flashing Devil3 kernel didn't help.
Anyone have any ideas?

Just try to flash stock software and again CM.

Try a older version of CM11, and if stability is a priorty stay on CM 10.2

OK, so I've tried a few things, and had a few surprising outcomes:
I've analyzed the CPU load with various tools, as Android Tuner, OS Monitor, and All-In-One Toolbox.
Most of them reported Android System using 30% CPU, and com.android.systemui using 25% CPU, all on the highest frequency.
But All-In-One Toolbox recognized top process instead of Android System as Lockscreen android process, so maybe there is a hint there...
(and I don't use any custom lockscreen stuff beyond stock CM's one)
So, backed up the current troublesome system (let's call it BKP_NEW), just in case, and decided to restore a full NANDroid backup I had from a week ago (and the issue is just from yesterday).
Restored all 6 partitions (/system, /boot, /cache, /efs, /modem, /data), rebooted, and....
...The issue was still present! Crazy battery drain just as before!
Very confusing... Then I went for a factory reset - it fixed the issue, but I have to start from scratch with all the SW installs and config, and I don't have a week to waste setting everything up again, and potentially running into the same issue some time later.
So, I've decided to move further back, and restored a two week old NANDroid backup > reboot > No issue presents
But it was just too weird, since the delta between 1-week old and 2-week old backup is infinitesimal.
So, out of curiosity I've decided to restore the BKP_NEW (the one of the system with the issue present)... and after the restore it works just fine! (WTF?!?!)
After thinking on it for a while, my conclusion is that there was some problem with some part of system that was wiped/fixed in TWRP's Factory Reset, but is not touched/overwritten during the NANDroid 6-partition restore.
But again, this is just my assumption, need someone more knowledgeable to confirm this possibility...
(maybe @ne0zone75 can advice on this?)
Since that, all is working fine (at least so far).
And if my assumptions are correct, @Ksenios, you can try to do this, and still have working system with all apps and configs (If youre comfortable with recovery / backups management).

hi,
(passing bye from google - just a note)
com.android.systemui cpu high usage (about 37%),
on my huawei media pad x2 (gem702l) but only while charging (and just sometimes), if that gives something for someone, any clues why ?

Issues after updating my M8( Poor battery life,Standby button not functionin properly

So,
2 weeks ago I updated my phone to latest version ( 3.29.118.9 ) 4.4.4
and now I started experiencing some problems lately mainly battery issues.
Battery drains very quickly,yesterday the phone had 32% of battery, I used greenify to stop apps like messenger,whatsapp.., I put my phone in airplane mode and extreme power saving mode and when I woke up 3 hours later 16%, The only thing I had on was the alarm. From 55 it goes straight to 12 when on airplane mode WTF ?
The second issue I face is the power button won't put the phone in standby mode, no matter what I do. Then I have to restart the phone by holding it for 5 seconds or more.
The third problem is the status bar quick settings, it takes maybe 2 or 3 taps to work, This can also be solved by by restarting.
Can anyone give me any solution.
Thanks

Do you have fastboot disabled?
If not do it, If so then maybe you need to put the unit into recovery and wipe the cache partition.

If you updated by official OTA, a lot of random bugs can often be resolved by doing a factory reset (backup any personal data first).
Also, have you tried to see what battery life is like without Greenify? These kinds of apps can sometimes do as much harm as good.
