how to troubleshoot random freezes and restarts

Hi guys, I have had a G1 for over a year now, and it has been rooted for that long. I began using cyanogen's mods since 4.1 or so, and they have been rock solid until recently, when I upgraded from 4.2.6 to 4.2.7. Ever since that upgrade, my phone has been "freezing" and rebooting at seemingly random intervals.
First, let me try to define what I mean by freezing: this usually occurs when the phone is put to sleep, and it just refuses to wake up. The screen remains black, however my notification LEDs continue to flash (if they were flashing before). Sometimes, the phone freezes while I am using it; buttons stop responding, and opening/closing the keyboard does not change orientation. The phone usually gradually slows down to a crawl before this type of display-on freeze happens. In both cases, I am able to restart the phone by pressing call+end+menu buttons.
For the restarts: these started happening recently, I'll guess after 4.2.9. This always happen while I am using the phone. It'll pause for a second, like it's frozen, then restart back to the G1 boot screen a few seconds later.
I have tried wiping, repartitioning my SD card from scratch, using the phone without any of my apps installed, etc. The only thing that seems to fix this is if I downgrade back to 4.2.6. I have tried to narrow this down to the best of my ability, but I still cannot figure out the cause. My question is, how can I begin to troubleshoot this? Is there a log or some way for me to see what is the last thing the phone tried to do before it froze/rebooted? Right now, I don't even know where to begin.

well for the phone freezing it MIGHT be too many apps running in the background and eating up CPU usage...download advanced task killer from the market, it allows you to close apps that run in the background.
as for the random reboots, i am almost certain it has to do with the rom you are on. there should be an app called "log collecter" in your app tray, it comes with the rom, try and get the logcat from it when your phone reboots, and send that logcat to cyanogen via the link he provides on his thread.

2 things that I can think about:
1. Wipe you dalvik-cache
if that does not fix it
2. This may be a good time to re-format the ext 2/3/4 partition of your card and do a complete wipe.

I have this exact problem, it first started with random sd card errors "removed sd card" with an sd card inserted, and now the black screen of death, I reformatted and repartitioned my 8gb transcend class 6 card and flashed latest cyanogen. Today I got the black screen again so I used nandroid and went back to cyan 4.0.4, I still got the black screen freeze running old rom but so far sd card is working so not sure what the cause is, bad sd card? I just got this card a month ago... or phone going bad?

yeah, i get the freeze, its usually when i am running multiple resource eating apps. Try advanced task killer for a convenient notification bar click away from closing apps.
I also get the other problem where it wont wake up! Seems like we are running into the same problems under the same ROM. When it doesnt wake up i usually wait a few seconds and try pressing other buttons than the menu button to wake it up when its not turning on. A combination of waiting 5 seconds and trying a different button usually wakes it up.

Hey guys, thanks for the logcat info.
The most frustrating part about this problem is that it is unpredictable; it just happens when it feel like it and is impossible for me to reproduce, therefore I cannot figure out the cause nor can I tell whether or not any changes I make have any effect.
I do have ATK, and I use it regularly. It still doesn't stop this from happening. In fact, I installed ATK in order to try to solve this, which means before this started occuring, I did not even have ATK installed nor did I have this problem.
Can anyone tell if there were any significant changes from cyanogens 4.2.6 to 4.2.7? I see the changelogs, but most of it doesn't really mean anything to me because I don't understand what its talking about.

Yeah I usually get the freeze after installing a new rom onto my htc dream 32a. I just take out the battery and put it back in. Then I reboot and have no problems after that.

try going back to previous rom you had and see if the problem still exists... could possibly be an issue with latest update for rom...

Help? Battery/Software/SD?

So I've been lurking around this forum ever since the G1 first came out. Messed up on the rooting procedure once, got a replacement a few months ago.
Worked fine so far. A while ago, I flashed the latest SuperD rom. I am using an 8gig SD card. I've overcharged my battery several times by accident, so the health isn't exactly up to out-of-the-box standards.
I noticed the phone entered a random reboot when I turned the music on for a while. As time passed, the random reboots became more and more frequent. Since I couldn't keep the phone on for more than 20 seconds without a reboot, I decided to wipe and flash a new rom today.
I chose Pays 1.6 Rom and flashed that. Didn't wipe my ext4, just wiped and flashed. I figured ext4 wouldn't cause such a problem, so I ignored it for now. Problem not solved.
I turn the phone on, and in the few seconds, I noticed the following:
the apps all show up, meaning the phone reads the ext4 apps (right?.)
The sd card itself displays an error - I can't access music, pics, etc.
Phone service is fine, all apps are normal.
Buuuut there's still that random reboot issue. It reboots, enters a G1 screen, then reboots quicker. In other words, after I take the battery out and reboot, it might take maybe 1 minutes before it auto-reboots. I wait, then it reboots in maybe 30 seconds. And faster and faster, until it doesn't respond anymore and I have to take the battery out again.
I'm not sure what I do causes random reboots. Sometimes it's when I press a button while in the music app. Sometimes it's when I open the keyboard. Sometimes it's just when the screen goes to sleep. It's fairly random.
I can go into recovery (once I take the battery out once.) Fastboot also works.
Running the danger SPL and the second to latest radio (I believe a new one came out recently? Mine's the one with 26)
Help please? What part of my phone is broken?
I'll give additional information if asked. Not sure what parts are relevant.

Sound's like Kernel panic. Wipe everything and install soemthing stable like cyanogens 4.2.15.1 or dwangs rom. Didn't know there was anything worng with SuperD's kernel though.

Since the rom relies on apps to sd I would guess the ext is borked and maybe the fat32 as well. I would reformat the whole thing to fat 32 then reformat to ext2 or 3. Load Dwangs rom for testing (easier to get running just as a test).

So I wiped my SD (ext4, dalvik, fat32) and tried cyanogen. Then I tried Pays. Reboot problem's gone, but neither of them is reading my SD card.
I'm assuming its just a matter of backing up the SD and repartitioning? I'll try that next when I have time.
Thanks for the help guys! Lastly, any ideas on why this happened? It'd be hard to pinpoint the exact reason, but I'm assuming I'm not the only one who had this problem - how did other people get to the situation I'm in?

I wiped all of my SD, repartitioned, wiped the phone, flashed AOSP 1.6. w/ root and "expansion" pack.
Reboots are less frequent, but they still occur too often. They don't occur by themselves - its always when I'm using my phone.
It seems that it reboots more when its connected to my computer. The SD isn't mounted, but the simple fact that its connected seems to trigger reboots more frequently. Is this a coincidence or can a USB cord trigger reboots?
Help please
EDIT: The phone just made an audible cracking sound as it rebooted - like someone stepping on gravel. Hardware issue?

StkAppService - com.android.stk restart loop?

Hello people, first post
I have this little problem that's been bothering me with my new O2X.
When restarting my phone, the SIM Toolkit service, StkAppService - com.android.stk, pops up in service manager, and seem to be running fine. After a while though, the service seem to get stuck on "restarting".
Haven't quite been able to lock down when/why. Seems to be connected to extended periods in sleep, or playing games, but this could be just random.
When shutting down the service manually, everything seems to be just fine, and it won't come back until I for some reason restart the phone again, then it it'll be back to working fine, and after a while stuck on "restarting" again.
Is this something I should care about at all? Just seems to me that having something stuck in a restart loop (could just take a really long time, not 100% sure it's actually looping yet) would drain my battery.
So, to the point. Could this be a fault of the phone itself (making it a warranty case), a bug with Android 2.2 (wait for 2.3) or an issue with my service proivider (in witch case I'll contact them)?.
Been unable to find the answer on my own, and this is my first Android-phone, so I consult you, the wizards.
Update:
Checked with a friend of mine who bought the O2X at the same time as me, and he also has StkAppService stuck on 'restarting'.
And the phone glitched out and refused to fall asleep by itself today. Restart fixed it though, haven't happened again.

Another Problem with STK
My problem with STK is another one:
I have two SIM-Cards installed in a dual-SIM-Card adapter. So with stock ROM switching between both cards via STK works fine.
Now I tried several CM7-based ROMs, but with all ROMs I receive the following error massage when switching to the other SIM (translated from German to English):
We are sorry! The process com.android.phone has been unexpectedly terminated. Pleas try again later.
After that, I can enter the PIN-code of my SIM and it is activated. I´m not able to switch back, when I tap on the app-icon it switches back to home-screen.
Any solution for that? (sorry for my bad English...)

Hi,
two years alter, I am facing the same issue, and XDA developers apparently are not working on including proper STKs with custon 4+ Android Roms.
It's a pity

[Q] SIM Card causing reboots on my Xperia T

Hi guys,
Earlier i found out that my sim card was the one responsible for the sudden reboots of my Xperia T. Does anybody know how to fix this? I am currently on stock JB 4.3 with locked boot loader.
Thanks for the help :laugh:

Hi there,
I would like to post my 2 cents here too, cause this is bug or whatever it is so annoying that I want to smash my Xperia against the wall.
It started shortly after I upgraded my Xperia T to 4.3 (.295). First I thought it is caused by wrong USIM placement, but even if I pull it out and follow the click to be sure it is placed properly, reboots appear from time to time. I was trying to track the source of this with "standard" steps like factory reset, installing apps and do settings without using Backup&Restore app, testing another USIM however without success, using phone with/without microSD card. I even upgraded to latest bugfixing .199 today but those damn reboots persists.
Maybe these observations will help to solve this issue:
- reboots appear usually after using apps using internet connection (mostly local news, gmail, Chrome etc) and, whats interesting, when screen is off
- mostly when on HSPA, not wi-fi
- when I play music, using PowerAmp, not tested on other mainly because I have no other installed
- sometimes after the call
- once or twice it happened when unlocking the phone
- reboots stops only if battery is totally drained or if I notice smell of the the burning flesh of my thigh and I put my screen on/or reinsert USIM.
I will observe more, but Im loosing patience
There were no reboots when on stock 4.1.2 with locked bootloader with root. I also had to turn off SIM card lock, because I need to be reachable. I like this phone, 4.3 is nicely done but this is driving me mad. I consider to downgrade and visit my local vendor, but beforehand I decided to ask community.
Sorry if this is discussed somewhere else here, I just spotted this post and added my POW. Thanks for your help

it may related to the battery

mine was the opposite, reboots all the time when tethering unless I kept the phone on charge on stock 4.1.2. now on 4.3 and only had two reboots after heavy usage, but the phone wasn't on charge and was hot.

Looks like the reboots are caused by handover between 2G and 3G networks. I have set my T to stick on the 3G only and reboots have disappeared. Two days without single reboot
However I have found strange dots on the display recently, like some layer of the display is too thin and light is bit brighter in these parts, so I need to pay a visit to my vendor anyway.

Theme
Hello. I updated to 4.3 rooted ROM, and always restarted and I cant start the phone when is SIM in. Tried reinstall via CWM, nothing helped. And... yes.. maybe installed programs caused this boot loop, try install step by step program to program and succes. I found Woody theme. When I setup this theme, phone cant process Sim pin code section at start. Deleted theme helped me, and now work fine Darklord Rom

Well, I have finally isolated issue and it is not related to cellular handovers. Reboots are caused by faulty mechanism holding SIM card in place. Despite I hear and feel obvious "click" indicating SIM card is in place and mounted, it is not. After undefined time SIM card gets loosed and you can take it out very easily. Not sure if this is just me or it is a construction issue, but I saw too many posts regarding reboots. Time to check guts of your Xperia folks..

This reboot issue start happening to me just last night, no Wi-Fi no 3G, just using "UBreader" (reading a ebook, obviously ) before sleep... it reboots 3 times within an hour calling for "sim/usim card removed"... After third reboot, I open the card holder and removed SDcard, nothing happen, then I remove the sim card and did it again [the reboot] this time on porpuse, so... yeah, I think what @daemin says is true, the mechanism for holding sim card gets loose after a while... sad but true...
Maybe, when holding the phone, we press to hard on that side without noticing and that cause the problem, I don't know... but this morning I check at running apps and all or mostly all say 7 hours "running" so I think phone didn't reboot after I left it there for sleep... who knows...

Freezes and restart... Died. What is the problem?

Hi guys since yesterday I have problems with my phone
the phone suddenly freezes over without being able to interact.
it restarts on its own but without ever starting the operating system in fact it shuts down and does not turn on again as if the phone had died.
the really strange thing is that the phone was fine Then suddenly he started making this mess.
Yesterday after so many hours of problems I managed to start the phone and now it works well but I am afraid that the situation will repeat itself.
the phone has the bootloader unlocked has root permissions, I followed the guides on this site.
But I have had this phone for two months now and these problems never occurred.
where can i start to understand what the problem is?

Mine suddently become all white, with the interface cut in half and moved up. i could do nothing. nor reboot nor shutdown.
after some minutes it turned back normal. i hope its color os bug and realme will fix it

It appears to be a firmware problem. We hope well.

Today did not give problems. This behavior is really strange, what can I install to understand the root of the problem?

I noticed that if the phone never goes into deep sleep mode the problem does not occur.
Now I am registering the log and as soon as the problem occurs again I go into detail to find out the real reason.
I'm trying to create an automatic script that is launched on the boot that practically never makes the phone sleep.

i'm really desperate the phone started to reboot itself.
I would like to try using a system log recorder but I realized that when I restart the phone these logs are not saved so it is impossible for me to verify the reason.
Can any of you help me out?
the phone freezes and then restarts.

Did you achieve any solution ?

No. I'm disperate.

Why don't you flash stock fw /recovery? Just to make sure it isn't an Hardware problem ?

I try but have this problem

@westenlive
The problem appears only when you use data connection right?
If you try to switch off data and use wifi , you will not notice
The problem is because of the the operator, try another sim provider

Yes, in fact, that could be the problem because a few months ago removing the SIM card the phone did not give more problems
maybe you gave me the solution. I'll try

I am now testing the LINEAGE it happened to me this I removed the SIM card and I installed the costum Rom, I made the various customizations and the phone never locked OR restarted.
I inserted the SIM card in the phone worked perfectly, then having messed up with luckypatcher I had to reinstall the Rom.
So I performed the same procedure with the SIM card inserted in the phone and already at the first start it was unstable with reboots.
Currently I have applied for a change of sim card.
As soon as it arrives I will try to remove the sim card Install from scratch The system is to insert the new SIM card only so I can have the mathematical certainty that it is the SIM card
I hope my experience can help someone

This problem seems true, my X2 Pro also faced same issue when enabling cellular data. The phone sometimes loses the signal or the app freezes and perform a phone reboot. X2 Pro is a mid-range flagship phone, and yet this problem should be solved before they start to sell the phone.

Yes this device has many software problems but hardware problems of this kind are not acceptable.
Practically mine has become unusable, as soon as I turn it on after a few minutes of use it start closing the apps by itself.
Then after AN intende use of 30 minutes it start to restart.
This phone is truly incredible
