I have upgraded my SGS2 to ICS (PDA I9100DXLP7) (rooted with CF-ROOT). All was fine the first weeks, then I started having occasional phone crazyness often when the battery was lower than 30%. Phone would reboot, gets very hot and keeps reboot until battery totally flat within minutes.
I noticed an additional problem which is auto-update was giving many errors such as : package invalid, not enough storage to install app (well got 300MB free for apps, 3GB on internal sd and 4GB on external...)... but manual install/upgrade always succeeds.
Then I started having issue of loss of mobile data connectivity... rebooting the phone would solve the problem..except that now almost everytime I reboot the phone, the cpu usage is at 100%, phone soft reboot (not full reboot) after a while (from 1 to 5 minutes). battery is being sucked at the rate of ~1% per minute!!! Usually it takes about 30 to 50 minutes of loop reboot before the phone can work... once it works and cpu is not 100% all is fine. Even plugged in the charger the phone barely maintains it's battery level, if plugged in usb, battery keeps going down!
cpu usage is caused by system server (100% cpu on both cores). I tried adb debug console, all I see is that the phone gets stuck for a while, then all processes are being killed and the phone soft-reboot.
I tried clear the dalvik cache and reformat the cache partition, didn't really seem to help. I tried disabling media scanner too, with no luck.
I now notice that most of the time the phone is stuck in that auto-reboot loop, the auto-update process is in progress... not sure if it means anything.
Anyone got any idea on what is wrong? is a full wipe/reinstall my only solution?
Thanks,
David.
Have you tried using Better Battery Stats to see what process is running to make your phone do that?
Hi,
It's mentionned in my post, the culprit is the process "system_server"
Wipe phone and reinstall firmware from a different download .

samsung fascinate frimware 2.2.1 its the super freakin clean rom ebo1 for baseband and build number ....the phone just shuts off randomly and i either have to do a battery pull or reboot with the poweer and volume buttons held in originally i thought it was a hardware issue so i got a new fascinate and this one is doing the same thing someone please help me
This typically stems from not wiping data as well as cache prior to flash...
Sounds like you have a rogue app locking the phone up while it's sleeping. I would do a factory reset, then install your apps one at a time until you figure out what's causing it. Allow the phone to sit idle, and maybe even reboot between installs. Allow the phone to settle down and enter sleep between each install and then try to wake the phone after it has been idle for a minute or two.
The other way would be to try looking at logcat with your phone connected to your computer when the screen is on, then when the display turns off and the phone sleeps. Odds are, whatever is causing the problem will be the last thing displayed if logcat stops giving you output. Otherwise, it should just repeat the same thing over and over (I'd assume so anyway) when it's trying to wake up from sleep.
My friend was having a similar problem so he flashed from SC 2.9 to the Deoxed eb01, wiped all the data on his SD card, and reflashed to SC 2.9, he hasn't had that problem since.
Yesterday when I was playing Pool Rebel online, it crashed once in the first. After a restart, it looks fine and was working properly except a little bit overheat.
Then the phone prompt a low battery warning, so I plugged the charge into it and keep playing, after a few minutes, seems like the charging speed is lower than the power consumption and the phone automatically shutdown. After a few seconds, I switched it on again, and the problem happened.
The phone looks like just been fully wiped and updated the rom, so I tried to install the titanium backup but failed, said there is no enough memory on the phone. I went to the application management and found there is no memory usage gauge on the internal memory tab.
Please help~
Phone: UK Galaxy SII (black 16g)
Rom: MIUI developer version 12.23
Hi,
my Galaxy SII runs on rooted CM10.1.3 which worked fine for a while.
Then it started to sometimes shut down all of a sudden. That usually was when I worked with maps (navigating). Then it also started to shut down when I worked with other apps that I suppose consume a little resources (eg. browser).
Whenever I re-boot right after the shutdown, it shuts down already during the CM start animation. With the second try it takes a little longer to shut down again. Usually I just have to wait 10-15 minutes to be able to re-boot finally. Sometimes only, when I connect it to the charger.
Just when it tries to run the scheduled Titanium Backup, after re-boot, it shuts down again, if I miss to stop Titanium in time.
After such a re-boot it usually shows very low (red) battery status. Just after it recovered after a short while, the BattStatus is back to its former value.
That happens no matter, if USB Debugging is enabled or disabled.
Even my former last resort (flight mode on - battery out+back in - flight mode off) doesn't help.
Today I wanted to backup to my PC before updating CM (hoping to solve the issues) just to find, that I couldn't connect to the PC anymore.
My App USB mode switch for SGS1 on CM shows an error message that I have to turn on USB Debugging to make it work. But USB Debugging was activated.
The processor is running at around 70% (1000 MHz) and+ 29% (800 MHz) when it got into this trouble.
I checked with Zooner Antivirus and it says, I'm clean.
Does anyone have an idea,
why my system shuts down
why it takes so long to recover
why I can't connect to the PC anymore
why USB Debugging is not recognized anymore
Those are many questions, but I'm sure, the answers point to the same root cause.
Thanks!
I could stop the massive CPU usage with Rescan Media Root. Now CPU is down to 60% (of which 97% (1200 MHz) and 1% (800 MHz)). Still, it looks odd to me that the CPU mainly runs on 1200 MHz though there isn't anything big running. Just the usual background processes.
It goes to deep sleep all right when I leave it alone. USB Debugging is turned off now.
Now my main concern is the sudden shut down of the system out of nowhere with the problem to re-start.
Has anyone found a solution for a similar problem?
Partly solved, but crashes still occur

I got this part of my problems solved. Somehow no USB connection mode was selected anymore and I just didn't find the path to get to enabling it (Alzheimer??).
Now I found it: Settings > Storage > left button: USB-Connection (PC)
Meanwhile I updated to CM 10.2-20131026-Nightly. Unfortunately I experienced another sudden crash lately after registering a call on Control your calls 2.9 and another while surfing via 3G.
So, these qustions remain:

I would still appreciate ideas regarding those crashes. It's so strange that I can not properly reboot right after the crash, but later on.
Okay, so, I'm using CM 11 M12 on my Galaxy S3 and recently I decided to be a daredevil (like an idiot) and flash Boeffla Kernel on my phone. I flashed it and messed around with some settings, I'll post what settings I changed to what.
CPU: zzmove governor, profile - optimal. Set the max CPU frequency to 1200 MHz.
Enabled zRam, set it to 4 partitions at 800 MB each with swappiness set to 95.
Enabled Boeffla tweaks.
After that, I noticed that the phone would sometimes freeze for a short period of time, which was okay at first, but then the freezes got more annoying so I decided to restore my nandroid backup and use my stock kernel. Well, that didn't fix my problem, in fact, it made them even worse.
My phone now freezes randomly while doing anything (browsing, playing games, opening apps, etc) for 30 seconds to a minute. And during that time period, the phone is pretty much frozen. Can't turn off the screen, can't toggle anything, I can only restart it by holding the power button for 10 seconds after which the phone still continues its weird behavior.
There are some odd things I noticed though:
1. I cannot transfer files to my phone using a USB cable. It stops at about 1/3 of the progress and the phone freezes (can't power up the screen, open apps, etc). I can only reboot it and stop the file transfer process. However, transfering files to my SD Card works, albeit it very, very slowly.
2. At first, the currently open app freezes but not other parts of the system. Let's say I'm using Chrome, i'm browsing and then Chrome freezes. I can still open the notification bar or the power menu, but the app itself doesn't respond anymore. After a few more seconds, the entire system goes unresponsive.
3. Restoring and making backups takes extremely long (using TWRP 2.8.5.0). While restoring a backup, the process sometimes stops for half a minute and then continue which leads me to believe that the CPU is under heavy load all the time.
4. During the freezes, the phone won't reboot itself automatically, but certain aspects of the phone will crash with an error message (like the Settings menu, lockscreen, the wallpaper will change to the default one, etc)
I also tried doing a complete wipe (data, dalvik and cache) and booting up CM 11 again. Right after I selected the language in the "Welcome" screen, the phone went unresponsive and very sluggish. Animations would freeze, get stuck and it was impossible to continue. I decided to restart the phone again by holding the power button after which I got into a bootloop. The only thing I could do is restore my nandroid backup again.
Does anyone know what the problem could be? Do I need to delete certain kernel files left over from Boeffla kernel? Is it a hardware problem? I seriously hope that this is something that can be solved by wiping data (i'm even willing to wipe /data/media) or by deleting certain system files.
Thanks in advance and sorry if this post is in the wrong forum or if it doesn't follow certain guidelines set by XDA.
Emmc nand damage caused by messing with partition, try reading the freezing thread in general forum.
There is no cure, only a partial workaround to teach the operating system to avoid the damaged areas.
My wife's OnePlus 6 started shutting down randomly, it usually happens up until 3 minutes after turning it on.
- It shuts down without notifying before - it's like someone killed the switch.
- It doesn't happen during the 1 minute boot up.
- Battery is charged to 95% and it still happens.
- It does not happen when connected to the charger (tried 2)
- Cleared up space from storage, she had only 500mb free, cleared 8gb.
- at twrp (it is rooted) wiped the cache partition
- tried logging using log cat, I have a saved log from during the shut down, didn't see and fatal log or something with "fatal", "shut" and "temperature"
- it seems to get quite hot at the top left side of the back side.
My next step is to factory reset, any ideas before I do this? Would like to avoid it obviously
Thanks!
goo day sir!! have you fix this issue? because its really a big problem for me thanks
