Can you go back further in the log before this entry: 06-17 17:40:22.273 E/memtrack(10099): Couldn't load memtrack module (No such file or directory)

Its trying to load something into memory it can not find, which starts a chain reaction. Can't tell what's what, appears to be a memory leak or cache issue from what I'm seeing, but can't tell without seeing more of the log.

I'm on T-Mobile as well. It says you're not roaming but aren't on the provisioning network. Are you using an ISIS simcard by chance? Did you have to manually enter APN settings? Any connectivity issues? Battery use seem higher by chance?

Under your settings in the power settings, turn off stamina mode and all that, I noticed it may be causing issues related to either Sony or google updates (I'd guess Sony). Also what is your Android System percentage of battery use compared to screen & google play services? It may be a bigger bug with the google play services but can't tell.

Thanks for the log..

didn't see your post till now

im using the Sim car provided by Tmobile as i have c6606, it allows me to download tmobile network settings, but i think i did manual entry. the android system percentage was i think ~10-20% no connectivity issues, and battery usage was actually pretty good for the one day i didnt get reboots. But yes the android system was at the top of the list, unless i played clash of clans which caused my screen to be on top
i had disabled most of google services to make up for battery drain,

About the log- because the phone rebooted at random times, as soon as the phone would boot up, i would let the system log run, ( don;t know how to capture the log using adb commands). Consequently, the log ended when the phone rebooted.

one day i was at work and the phone rebooted like 10 times, completely drained my battery, therefore out of frustration i just reverted to a 4.3 rom ( existenz) and the phone has been running better than ever.

thanks for actually taking a look at the log !

i did some more digging, and found that post above ^

stamina mode seems to be the issue, i havn't tried it as of yet, but it makes sense becuase reboots only occur while screen is off
is this likely? ( because anything is possible )

would it possible to use the stamina mode app form JB in KK?

You may want to back up your data then. Download towelroot and run it. Should root with no reboot. Then download terminal emulator.

Run it. Type su, hit enter
Then type mount --o remount /system rw

Then do a factory reset. This makes sure the wipe process was able to overwrite the system partition. Sounds like you may have left overs from the last Ota update perhaps. I had same issue, and it help get rid of the reboots. It has not happened since I wrote last time

Oh. On mine, I immediately realized this was the case as some menu options were different.

Good luck!

This would be after installing the Kk rom right,

Just in case a solution was found, I made a nandroid backup of the installed rom, will flash (already rooted) will remount system rw and then do factory reset

 

[alientango]

Oh OK.. Good luck let me know how it goes.

just to be sure, after typing the remount command, it should tell me Usage right, and then boot to recovery and factory reset?

Edit: tried, but during flashing, symlinking failed

 

[ahsank128]

So what after that failed, i used the Philz Touch Recovery to wipe the system data and cache partitions, afterwards, I mounted the system partition, and then flashed the ROM, so far its working w/ stamina mode on,

i plan to wait to see if it restarts, if so will continue with stamina mode off

No. That means it didn't go through

su, return
mount -o remount rw /system

It should just return waiting for next command. I just confirmed this works.. It's a single dash, BTW..

will do this, but then won't it unmount when i boot to recovery; to do a factory reset and flash?

so far, the mount system parition using philz touch has been good, and no restart as of yet.

sorry to be so clueless lol, im still a less than novice user
if possible tell me if this is correct procedure]]
1. on rooted software, run android terminal
2. su (enter) --- mount -0 remount rw /system
3. boot to recovery
4. factory reset
5.flash

assuming it worked now?

Looks like it that makes your system partition read and write. So you can edit any files under /system

Always be sure to put it back to ro if you manually switch it..

Same command, just change the rw to ro

@alientango
and in the above post, are the steps correct? becuase using twrp to mount still gave me reboot w/ stamina mode on

thanks so much for your help,

yeah man, it has worked, but specifically if i keep the Stamina Mode off, that seems to be the cause of the problem thanks for your help

I had that problem before, I had to installed inompatible xposed software. My issue was solved by not using StaminaMode apk

 

[Severus15]

I have this Problem, too.
But I have not rooted my Device. It is just Stock Firmware via OTA Update. I did a Systemrepair via PC Companion twice. But the Device is still constantly rebooting since 4.4.2....

 

[ahsank128]

Even with the release of 4.4.4, my c6606 still reboots only if im on stamina mode and the screen if off. I wonder if it has to do with the kernel.

Since i started going back to college stamina mode is almost essential now. :crying:

still cant find a fix, and i cant obtain a log, only reboots if stamina mode is on,
