Phone reboots randomly - Samsung Galaxy S II Plus

Hi. I was playing music when it first reboot.. Then it reboots again after that maybe 30min later while im browsing it reboots again im afraid it keeps on rebooting.. Please help on how can i find whats causing it.. Im using GT-I9105 cm11 build 3
P.s
Im not experiencing any lags before it reboot just a sec of not responding screen then reboot
EDIT
while im resting i noticed my phone light up with cm logo means it reboot again.. Im not doing anything on the phone i just leave it charging.. I really don't know whats causing this

Did you try reinstall cm11 or reset to factory? How it behave when you stop browsing music, or without sd card and without sim card? Some time ago I had similar problem after install cm10.x. Can you get adb logcat?

I cant get logcat.. But i think its a hardware error coz i switch to stock rom to test if it randomly reboot but still the problem occurs..

Try with other battery, or check if all buttons are on their places. If it's still rebooting you can start searching new device

[Q] Freezes then reboots

My Galaxy S2 has suddenly started freezing and rebooting after 4 wks of previously working flawlessly... anyone else had any probs? It will just freeze then reboot and also, last night froze on the O2 splash screen for about 1 minute on shutdown.
I had no problems until I installed an SD card and APPS2SD APP.
Next time it freezes, i'll move all my APPS back to phone and reinstall all moved APPS and report back if it solves prob.
Any Android diagnostics tools to monitor or read errors if any are logged?
I'm sure it's not the phone's hardware as was working perfectly before.

but u have a custom or stock rom??
if your phone stucks when boots u can use the android sdk and via adb parameters u can enter this in the shell when your phone goes to boot,,
Just enter the following command in order to view the boot process.
Code:
adb logcat
with this command u can see the problem on boot.... and solve it...

Weird problem, home button doesn't work

So two days ago i restarted my phone and after that my home button did nothing.
it would still wake the phone if it was locked. but other than that nothing.
all my settings for the status bar were reset too. (things like which toggles are there and indicator color etc,)
they were all reset to the default. (this includes the data connection getting turned on)
Since then i have tried two different roms and both of them ended up with the same problem.
It always happened on a random reboot. (i.e. it doesn't happen on the 1st reboot, but at a random reboot)
Anyone know what the problem is?
I dont know why this happens and there is no other way then to flash a new rom.
Wipe everything in recovery and flash a new rom thats the only solution!!

I haven't been,
usually i my max is 729 which has always worked fine.
but after this problem started i did go down to stock (600)
but the problem still occurs
729 is ok.
It might be due kernel or some app with root access.
Someone who cook Roms could explain the reason!!
Edit: Btw Which rom and kernel are you using??
Take provision.apk from the ROM's zip and put it in /system/app/
After that, set it's permissions to rw-r--r--(644) and reboot

I had this the other week, along with a couple of other little problems, ended up being that only factory reset would fix it. Don't know why it keeps coming back for you though.

[Q] Bricked... and bad battery :(

Just to explan in short notes how everything started..
I was using "ICS GPCR V2.1 by P-VLAD" happily for about a year i think, didn't have any problems. Then one day when i started to play some game my phone just turned off. After that i noticed that my battery drops to zero when i turn my phone on again. I noticed after, that my phone shuts down always when i watch 3d stuff or when my flashlight is on, after 1 or 2 minutes..
So i thinked it's time to refresh system.. So i went to factory reset on phone settings (not on recovery). Then i fell in bootloop. I don't know why but then i started TWRP and wiped cache, dalvik, system.. And that's it, im now in bootloop.
After that i accidently saw that i have inflated battery, so system probably was not the problem..
I readed everything from around this and...
Flashed again TWRP, bootloaders with "SimpleTool" and "OS Hacking" (tried them both), then i tried again to flash P-VLAD ROM but nothing, just says "booti: mmc_read 0x55e2dc" and bootloop stays. Tried "Universal_RecoveryLoop_Breaker.zip", then flashd everything, but it's same again.
I don't know it's possible because of bad battery that those tools cannot do their job. Also when i flash ROM i must get phone to charger..
What to try next?

[Q] Restart loop(not bootloop) - really weird

Hey lads,
I got a really weird problem and I've tried nearly everything I can think of. I had EMUI 2.3(b121sp06) and I tried the online OTA update to b307 if I remember right(was automatically suggesting the update) and at the update screen it loaded to about 99% and then stopped. Said not to press power while on this screen but obviously it wasn't going to finish. So I reset the phone and it started the "recovery loop", so basically keep trying to apply the update. I had to flash CWM to break out and flashed the whole system by hand(recovery,system,boot,cache,cust and userdata img files) and it starts up but it keeps resetting and seemingly it's random. Android boots up, I don't touch the phone--> boom reset. Weird thing is it even does it in recovery.
If I really want to explain the problem it's like as if my finger got stuck on the power button(that naturally made me think that the button might be f*cked), but booting into fastboot and not having resets cleared my suspicion. What I also noticed is that every time it boots up it doesn't recognize the sim card and I have no signal or whatsoever.
Tried multi tool unbricking method -> doesn't work
Tried factory reset from stock recovery(had to be fast so it doesn't reset before) ->doesn't work
Tried wiping dalvik cache and factory reset from CWM ->doesn't work
Tried killing battery by letting it keep resetting -> battery drained, reset loop stopped ->put the phone on charger->reset loop started again
I have no f*cking clue how can I get out of this, will keep trying though. Any help is appreciated, thank you!
Hi
Did you try to remove the Sd Card ? Honor 6 reboot is often due to faulty SD Card.
Which model do you have ? L04 ?
B307 upgrade sure ?
Seb
Yes, that was my first idea, still does it though. I have the L02 and I'm not positive it was b307, but it started with 3, could be b303 if there is one.
I don't know for L02 but for L04 there is a Full ROM that you can flash with the three buttons method. (Vol+,Vol-, power and put the ROM in /dload folder on the SD card).
Maybe there is such thing for L02 ?
There is, but as I said the phone restarts even in recovery. It's like the phone restarts every 30 secs except for fastboot.
if it's not SD card or internal flash problem so, it seems to be hardware related to me (
Would make sense but it occurred only after I tried OTA. Would be really surprised if that killed that hardware :-/

Unfortunately not, I'm out of ideas, trying to negotiate with the seller to sort something out, I think the phone is beyond saving

Its might be a battery problem Or power flex cable. Try to turn on the phone during charge
guys im facing the same problem now... waiting for any solutions
I have tried stop & uninstall some app
I've tried as quickly as I can when the phone (nokia x) is on, then I stop> uninstall I consider potentially cause this problem (facebook, whatsapp, uc browser) and then it managed to prevent the continuous restarts. but problems arise even though the application had me uninstall and then I restart the phone. and it is back again, I uninstalled the app that has remained with the error settings and restart repeatedly. who knows what else : '(

Did you follow the guide here?
Sent from my Honor 8 using XDA Labs
In the past my battery lost it's endurance pretty much. Furthermore I've read that a defective battery causes lots of weird behaviours on our Honor 6, which was the same to mine.
In my case a replacement of the battery worked well, to get my Honor 6 back to life:

It's not that difficult and lasts approx. 30-45 mins. Spare Batteries are available for 6 - 10 bucks on ebay or directly from the chinese internet stores.

Random bootloops and weird issues

Hi all!
My S7 is unrooted, completely stock, running latest 6.0.1 official update
Few days back I updated some apps from the play store and after that, my phone suddenly restarted on its own
This sudden restarting kept on increasing and currently the device boots up for a few seconds, and then freezes and restarts again
I know there's some faulty app that's causing the restarts, because once i managed to turn the UPSM on before the device restarted and it worked fine, with all the apps disabled
I have tried to get a logcat to look for the issue but I can't do that properly as I haven't taken any logcats before and i'm not familiar with the process
I have already tried to flash the stock firmware but that didn't help either
Is there any way or solution to get this fixed? Or can anyone here help me on how to get a logcat so that I can look for the error causing app?
There's a lot of stuff on my phone and I can't risk losing it by factory resetting it
I would boot into safe mode, backup my data first. Then start uninstalling apps I do not need and see removing which one fixes the issue.

I've booted into safe mode as well, but that isn't helping either
The same keeps happening in same mode as well. The device boots up, and after some 30 seconds it freezes and restarts and gets stuck in a loop
