[Q] Device freezes and reboots frequently after each battery change - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Hi,
since a couple of days the phone freezes and reboots frequently after each battery change until network time sync is completed... In detail:
- After reinserting the battery and restarting the device it boots normally, I can enter the code to unlock the SIM and the touch screen is usable
- After a few seconds or so, the touch screen freezes, and does not respond to any action. The home and back buttons respond though.
- Then after a minute or so, the device restarts but does not ask for a new code. Is usable for a few seconds and freezes again.
- This cycle continues until the device has sync'd the time. After that it runs stable.
The device is rooted but runs the stock rom (4.1.2). I wouldn't be surprised it some app causes the trouble, but how can I detect this? Played with logcat already but there's not enough time to start the log recorder after a restart before the system freezes the first time.
Thanks in advance for any help and hint!

G1 is constantly freezing

Hi!
I have a g1 and its freezing constantly. before one month it starts to freeze and I downgrade it to rc29 and root it and put cyanogen 4.1.999 and continue to update all cyanogen releases and it stops freezing. Now I am runing 4.2.4 and before two weeks the freezing thing get started again. first it starts to freeze when it get hot, when I use it for long time and it get hot in my hands. That was rerely happening first few days. Than it starts to freeze when charging and lately even when on standby. If it freezes when on standby the phone don't respond in any way only some times the volume buttons work and I can hear the sound of changing the volume when I press it, and even sometimes I can receive calls but the display don't work and no lights on buttons part. On the other hand when it freezes when I work on my phone it just freeze and there is no any respond from the phone. Buttons light are on and display is on. sometimes it get off, sometimes the display get off and buttons light is still working. Some times the freezing thing start in stages, firstly touchscreen and ball press won't respond. But I can move to another icon using ball and even enter it using the enter button on qwerty keyboard. And after some time even that part stop working and the phone is completly freezed. when I pull the battery out and return it back right after some times it wont turn on. And I just pull it off and leave it like that for half hour or more and it turn on normally. The only issue last few days it even starts to freeze while booting. I make a logcat and grabed the last_kmsg and its available in the attachment.
I hope someone is going to help me
ps. The phone is without warranty and there is no t-mobile or htc service center in my country.
Sounds like a hardware issue man, you may be SOL... You can try wiping everything, and re-flashing cyanogen 4.2.5, and see if that helps your issue.
Also, try underclocking your CPU, to help it not overheat as much, as that seems to be what your saying is causing the problem.
Leme know how that works out.
Try flashing a build that did not freeze for you, and stick on it for at least a week or two. If that build starts to freeze, it may be hardware.
I did wipe everything and put a fresh cyanogen rom 4.2.4. and it still occur.
How can I underclock my CPU?
btw. Thanks for help I hope its not serious hardware problem...

a question about strange reboots

Twice now ill be using my phone and it will kinda stop responding and then my trackball will start pulsing, it then reboots gets to the lockscreen and reboots again. It will do this until I pull the battery. Any ideas why it does this? Is my SD card going bad maybe?
-------------------------------------
Oh I forgot to mention I am running cm 5.0.7.1
---------------------------------
I don't know if that's the cause, but it did the exact same thing to me today too. Also running 5.0.7.1.
I was reading a book using Aldiko. I wasn't touching anything at the time (I was in the middle of a page) and the phone just reset.
Except that when it reset, it didn't fully reboot.
It didn't give that little vibrate pulse and show the colored X and the unlocked icon, it just started into the boot animation.
It got to the lock screen, but even before I could unlock it, it started over.
After I pulled the battery, it was fine.
Last few days i have been having these same boots, not going as far as the X+padlock screen, and continuous reboots until i do a battery pull, i am running froyo+cyanogens kernel.
I find i always have the headphones in when this happens.

No headphones here. It has only happened to me while reading an ebook with Aldiko, but I'm guessing that's just because it's a long period of phone activity.
It's probably less likely to do it when it's sitting locked and idle.
it happened to me also for the first time yesterday, just as you describe...phone reboots, gets to lock screen, and reboots again.
i had pandora on pause for a while...and thought that might have been the cause...since pulling the battery and rebooting i have not had the issue repeat itself...yet.
I have experienced three similar strange reboots since upgrading to Froyo. All three occurred while the phone was charging and i was using an app. Once the reboot loop begins the green charge light on the phone never goes away until i pull the battery.

Phone not locking

The other day my phone started acting a bit odd as it is no longer getting locked when the screen is turned off. Normally it would lock itself after 30 minutes if I leave it untouched, and immediately if I click on the power button. Now when I turn the screen off it doesn't lock itself. Sometimes when I exit the camera or another app the phone locks itself. Also, the screen comes on at random times.
I haven't installed any new apps lately and have experienced this on Monxified and iHacker roms, so it doesn't appear to be rom specific. Is there any way to check what could be causing the non-locking and random screen on issues?

can't switch off and eternal boot loop

Hi guys,
Funny thing happened today, taking the phone out of my pocket and in the process i manage to restart the phone and it has been restarting ever since......
Its a 1068, rooted with radium redefined MM rom. The phone has been great for 2 years and i had no issues until today.
So basically the phone continues to restart back to the unlocked bootloader screen and then restarts again.
Nothing i have down can actually switch it off, all manner of pressing sequences etc and for various lengths of time have no effect. You think okay i have it now....it's off.....but then 3 secs later it turns back on again, vibrates and does it all over again......
I ended up taking the phone apart and disconnecting the batter cable and left it for a while, plugged in the power only and then reconnected the battery hoping this would somehow help........but no.....the eternal boot loop continues.
No way to switch off the phone.
Can't access recovery via the power and volume keys
Can't access recovery via pc with adb
I read somewhere that with a low battery this boot loop thing has happened to others but i couldn't find the thread again and have no idea if there is a fix.
Anyone have some bright ideas ??????
Thanks in advance

HTC Desire 500 strange behavior after app. installation attempt

Hello everybody,
I'm not an expert in android or any other phone software, that's why I kindly ask you for help.
Trying to install an air company application from Play store on my desire 500, I got a message saying there is no enough memory to install it. The phone froze with this screen without any reaction on touching, sweeping etc. The only thing I could do was to restart it. After initial screen and entering SIM card PIN code the home screen appeared and began blinking at uneven periods of 0.5 - 1 s. It wasn't possible to control it in any way. Yet, the phone became hot and quickly drained the battery. I removed the battery, put it back, charged it and turned on the phone - it showed the same behavior. After 200 attempts I managed to unlock the screen and to make it operative. Didn't find anything suspicious except that it's hot, takes more current than the charger could supply (battery diagram goes down although charging is on) and reacts very slowly on touching and sweeping. When connected to computer HTC sync manager starts automatically but doesn't establish connection (No phone connected). After expiring wake time and the screen gets black and power button is pressed, the same blinking appears.
I made a hard reset (luckily I have a backup) but nothing changed even the phone is now completely naked, as came from the shop, without additional apps, files, contacts, nothing.
Please advise what could I do to solve the problem. This is my only phone and I can't afford a new one.
I could give all info I have concerning firmware, OS etc.
Thanks in advance!
Best regards
Emil
