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...

[Q] Foce close error all installed apps not showing 2nd time...

Hi,
I have a rooted GT-i9000m (bell Galaxy S Vibrant). I used the one click lag fix to root my phone and it works fine.
A few days ago out of no where all the apps started auto closing as soon as i opened them and then both the menu and back touch buttons lit up and the screen went black. I held the power down till it rebooted only to get and error with com.android.calendar even tho I never use the app. When it finish's booting none of my installed apps are showing.
The first time it happened with com.android.app and I did a full wipe and factory reset and just reinstalled everything.
Ideally I don't want to system reset to factory settings again and lose all my files and notes that i copied back on to the phone 2days ago...
Please note I have tried clearing the data for the calendar app in settings -> apps and i cleared the calendar back up. My problem is that none of my installed apps are showing...
(Update) I also cant reinstall or update apps due to a Installation error - Insufficient storage. But there's room on both SD cards. I also set 850mb for apps when i did the one click lag fix and i don't have 850mb of apps installed.
(Update 2) I did a factory reset again this time i didn't format the internal and external SD cards. (It works like new again) Thus I got to keep all my personal files and ring tones ect. The only thing that was deleted that I didn't back up is my Notes. This leads me to my new question whats best for backing up apps on a rooted SGS (bell Vibrant)?
If anyone has answers they would be much appreciated.

i had the same problem
install rom manager from the market place
there is a option in there "Fix Permissions" just run that and it will fix it up for you
only takes 1-2min to run

Tried what you said but i cant install anything... I get Installation Error - Insufficient storage available.

I now understand the cause of the problem. I change my battery once and some times twice a day. At first I would wait for the long shut down (untill the screen goes totaly black) and then take off the back and swap out the battery. At least 3 times the phone would boot up and ask me for the network unlock code (I bought the unlock code directly from bell for 75$). I found this rather annoying so i tried just taking the battery out wile it was on (idle) and it appeared to work flawlessly at least 20-30 times before the phone would start to do an endless force close loop cycle. This kept forcing me to do a factory reset on the phone. I can only assume the one click lag fix and my disregard for the need of the shutdown before removing the battery must be all the cause of my problems.
I will try and see if my phone is more stable with out the one click lag fix.

nope that is not the cause of the problem
but it sounds like you are another victim of the lag fixes that is killing your internal SD card.
not the fault of the lag fix, it just make the problem apear sooner than later

I have been having a similar issue and I'm using Voodoo lagfix. I think it's because I took the battery out before it had completely shut down.

Well the phone bit the dust today. I opened up google maps to look up an address and it crashed with the usual error. So i rebooted the phone and now it stays stuck at the boot logo. (the glowing S with both touch keys staying lit) So i did the recovery thing again but this time I had to do the Vol-up + home + power in order to get the phone working some what. IDK but it wont let me log into my google account to sync my contacts. My APN settings are correct and working and I even tried off my Wifi at home. I'll just hope its a google problem and not my phone acting up. Thanks for the pointer to the bad internal SD. That may be the problem kinda hard to prove it to Samy thoe...

I get force close errors after about 4-7 days of use. Now its gotten worse. A few days ago I was looking up an address and my phone crashed and rebooted it self. It then hug at the S boot logo for 20mins. I got to my friends apartment building to find my phone still stuck at this boot logo. I couldn't remember his apartment number or buzzer code... Normally i just check my contacts list and buzz the code. I was standing out side in the Canadian fall cold wind trying to get this phone to work... OMG i almost just smashed it on the spot. Anyways I remembered about something i had read on this forum about the recovery mode ( i had used it to root ) so i tried that out got the little menu and tried every option before having to do the dreaded factory reset. Well nothing work with the exception of the factory reset it got my phone working in about 5mins... LOL
Anyways I thought I might try upgrading the firmware when I got home. What a mistake... I cant control my phones MP3 player via my bluetooth car stereo any longer. Tried everything even a factory reset and formatting the internal and external SD's. I tried running it with out rooting it again and with out the lag fix in hopes that I wouldn't get a force close error. Wouldn't you know it about 5 hours after the factory reset un-rooted just after i finish coping over all my music. I get a force close error! So I tried again and this time the phone ran for about 30hours before it started giving me force close errors about the email now...
Sigh I've tried just about everything in my power to make this phone work. So I assumed it must be the phone... I called Samsung up to get a RMA going... Wouldn't you know it they tell me that I have to call my carrier to get it RMA/repaired. I try to explain that I bought the phone with out a contract and bought the unlock code from Bell so I could use it on Fido. They tell me to call Fido... ROFL Fido wouldn't even give me their APN settings when i got this phone so knew they would be of no help. They don't even have one android phone in their line up i tell the sammy rep. So they tell me I should go back to the Bell store I bought it from to get it repaired/RMA'ed.
I doubt Bell will be of much help but here's hoping.
Do you think my phone is broken, bad flash, buggy memory, ect and needs to be RMA'ed?

Update...
I got my phone back from repairs 2 weeks ago. They flat out replaced the phone for a new one. This was a huge headache for me because the new one wasn't unlocked. Took Bell 2 hours to get the new one unlocked wile my wife waited out side double parked downtown! (I thought it would be a quick pick up and I would be out) The blue-tooth works flawlessly again!!
Much to my dismay the replacement phone has started acting up much like my first one did. It gets several force close errors a day and has gotten to the point where it no longer can send or receive text messages (using Handcent). The stock Music Player app also force closes at random with more frequently. It looks like I got another Lemon. This time around I did NOT root, lag-fix, or flash firmware. I will be sending it for repairs as soon as I can afford to buy another phone to use wile this one is off at repairs. My back up phone is a 3~ year old Iphone3g that my son has made his... (cracked screen, vol rockers dont work, power button is jammed in, the LCD screen it self is bleeding on the top edge)
The Vibrant never let me down other than as a phone. As a divx player or using all-share it rocks! I use these features A LOT to play my 720p divx movies on any TV or the projector in the bedroom .
with that being said I might keep the phone just as a portable movie player to bring from place to place and put my sim in something more stable.

random reboots

This is more of an answer than a question, I recently had a problem with my phone doing random re-boots, a search through the many forums gave no answers but I saw that there were many with similar problems.I my case I had both dropped my phone with the battery and cover flying off and I was also busy trying a custom ROM install. My first action was to go back to the stock ROM for my phone (Motorola milestone XT720) without rooting, the random reboots continued. The reboot was always back to the initial screen (as with switch on) but the SIM login was not lost after the reboot. I then installed "catlog" to see if I could catch what was causing the reboots, this proved nothing and there were no errors or alarms being logged, I also tried recording the logs through ADB with the same result, it just stopped logging and ADB went off line. I tried changing the SD card and re-formatting the card without success. I tried limiting the CPU speed and voltage without any success, the very last thing I tried was to replace the SIM card with a spare and this cured the fault, placing the SIM in another phone caused problems with that phone. I have now swapped my SIM card and all is fine, the SIM card was working fine most of the time. The moral of this story is if you have reboot problems check the SIM card first and not last.
I hope this helps anyone who is experiencing the same symptoms I had.

10x for sharing this useful information
Mine reboot himself just a few miuntes after poweron
Also was very hot, especially when talking..
My sim card was old, not "3g", i have replaced it, but reboots still continue.
Next plan is to try without sim or with sim from other operator

Thanks for posting the informaiton, will give it a try next time my phone reboots itself.

I do think the SIM is not the issue most of the times.
For Milestone 1, DSI errors cause many reboots. I also experienced more of them when overclocking.
Also, 2.1 stock rom was rebooting like crazy.

Mine reboots once in a while when:
- some APPs are updated
- I connect the USB-cable
- during weather app-update (refreshing weather data)

I had same problem with a vodafone sim. It caused reboots very frequently so yeah it sometimes maybe sim problem although now I have reboots on cm7 rc12 once in two days and I don't yet know the reason.
Sent from my Milestone using XDA App

There are a few reasons:
Apps that overload the RAM,
OC(Heat),
Widgets that overload the CPU so it crashes,
MotoNav(on 2.2),
unstable kernel itself.

i also think, it could be because the kernel

I had this reboot problems at the beginning, lot of reboots maybe 10/15 a day and sometimes 2/3 on the row!!
Tried changing rom (original), tried changing SIM with a newer one (this has decreased much the reboots!), but still having reboots...
Sended back to Moto support, and back to me with same problems...
Now that my GF is using it, with same operator and CM6 no reboots at all...
Maybe the sim or the microSD...
Hope my experience can help someone, i know is "a bit" frustrating issue...

[Q] Has anyone with an Xperia TX faced the Sleep of Death (SoD) problem?

Hi,
I bought an Xperia TX about three weeks ago. Since then the phone has gone into the sleep of death state four times! I've read all the discussions regarding the same problem in other phones such as Xperia T, V and Z, and applied suggested fixes such as turning the WiFi off when not using the phone. But, alas, none of the suggestions has prevented the problem. On the other hands, I should be happy because there are some people with Xperia V whose phone hangs four times a day!! I am very surprised because apparently this problem occurs for Sony Xperia models more often than for other brands. I hope the problem to be a software related one and to be solved by an update fix, though some Xperia T owners who have updated to JB still face different problems. Please let me know if you too own an Xperia TX and have faced this annoying problem.
Many Thanks

Actualy you are the second owner of tx to Face SOD dont expect much replays here

I am not sure if it is just your firmware because I am on. 197 and no problems. Most people are on. 197 as well so probably not many with that problem. You can try doing a reset through pc companion and that might fix it. It seems to work for various issues that have come up for others.

You had 3.212 on it when you bought it or did an OTA update?
Try a PC companion repair.

I had 3.212 when I bought the phone. The phone is being updated to JB right now and I wish the problem would be fixed by this update.

i got my TX a couple of day back and root/flash to FXP213 now. I have tried FXP208 to 213 and this SoD occur in all version of ROM.
i;m trying to get the log for the ROM guy to take a look. I've trie dth wifi off too but still SoD. I notice if i left the phone in sleep mode for over 2 or mayb3 hours, the phone will juz sleep to death.

Actually i have been getting SOD since a couple of weeks on my TX. It happened when the phone is charged overnight.
Another thing i noticed is that each time i reboot the phone after the SOD, it says my my SD card is unrecognized and if i want to format it.
I just took out the SD card for the time being thinking it was causing the SOD.3 days since i removed it and no SOD yet. Any ideas?

Hi,
One of the guesses about the causes of the SoD problem is in fact SD cards. However, there are reports about having the problem even after taking out the SD card.
Have you updated your firmware to JB? Since I updated mine 5 days ago, I haven't faced SoD (touching wood!).
So, I recommend you to upgrade youlr phone if you haven't done so.
By the way, I vaugely remember that those who complained about the SD card cusing this problem, recommended to use SD cards of classes 2 or 4 (and not higher classes).

using ICS 3.212 a month
never facing any SoD
using from 3.212 Russian ftf
and I'm using sdcard 32 GB class 10 without any problem
never hear any information, that higher sd card class give error or SoD to some phone, except for bad sd card. . .

I have been having a similar issue with my TL ever since I upgraded to Jelly Bean about a month ago. For the first two weeks everything worked great and I loved the new update, but now seemingly out of nowhere my phone is starting to act up. At seemingly random times my phone will either freeze or hang or just generally not respond, the navigation buttons disappear and holding down the power button will not let me shut the phone down. The first few times it happened a message would pop up telling me that some process or app is not responding and I have the option to either wait or force close it. Normally I just tap "Ok," and then a slew of messages pop up, basically every process and app crashes simultaneously, forcing me to restart by holding down Vol up and Power. When it powers back on everything works fine again, but sometimes it will do this as much as 4 times a day. It doesn't seem to matter what I am doing at the time or what apps I have open. Sometimes I will go to unlock my phone and it will be stuck on the lock screen (I can lock and unlock the phone fine but no navigation buttons are visible and I can't tap on anything). It seems like now it will just say "Xperia Home is not responding" and I am again forced to restart.
Not sure if this is what you mean by SOD, but it is quite frustrating seeing as everything worked flawlessly about two weeks post updating.
I am using the Xperia TL (LT30at) 4.1.2 build 9.1.F.1.120 Kernal version 3.4.0

I flash to FXP and i get endless reboot and freezing. I like what the folks at FXP does but i can't seem to solve my problem after a week. I just flash back to stock ROM and (god forbid) i have not seen any reboot or freezing the past 8hrs. if u are on custom ROM, consider going back stock.

Sorry for the late reply.
Yes am updated to JB and rooted.
Since i removed the class 10 SD card, No SODs....not even once.
Only thing is that sometimes, when unplugging the charger, the phone does not get the event right away and charging light stays on. After a couple of minutes it goes back to normal.
At least no SODs....

No, like I said I have never tried modding or rooting my phone. I am on stock JB firmware from whenever I updated my phone a few weeks ago. ICS never had any issues like this, JB never had any issues until two week into the update. I'm just confused as to what happens to make these issues occur, I mean, everything was working fine and then for no reason something is causing my apps to crash and my phone to freeze? Doesn't make sense to me...

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
Next time buy ONE PLUS
