[Q] random reboots, way to find cause?

so, i previously had a rooted ROM. one of the stock rooted 2.2 roms that came out a while back. 2.09? and now the new rooted stock roms are out, 2.10? so i tried to install that. used rom manager and installed from SD and everything went well. but now i seem to have a problem with random reboots. haven't quite found a correlation between anything causing reboots yet. is there a way to log what happens to find out what may be causing the reboot?
or should i try flashing a new radio? i really don't see how radio's affect stability (came from winMo where it didn't), but i've seen reports about that here.
i have already tried restoring to my previous rom (via rom manager) and the random reboots are still there.

Well radio is how hardware communicates with software so I would guess it would be that.. in rom manager there is a rom download section.. click on NeoPhyTe and at the bottom there are radios so just flash one of them

1. hard reset. is it still doing it?
2. adb logcat. <- this logs what is happening with your phone. but without knowing what is causing it you could be watching your logs for a while

So was a cause found? Reason for asking is because quite a few of us are starting to get the same problem including myself .

Strange Browser Crashing

Hi,
First off, apologies if this doesn't belong here, getting confused as to where things should go, can someone move it if it's in the wrong place please.
I have Flashed the LeeDrOiD v2.2d ROM and when accessing the Stock browser it will randomly crash, it's a strange crash because normally a crash will mean that you will exit from the browser and next time it will load to the homepage, on mine though it will sort of crash but then load the page I was on, even if it wasn't my homepage, if I had any tabs open I would also lose all of those, which is how I know it's crashing.
This isn't specific to this version of the ROM though as I've had this since v1.4 or to any ROM because I've Flashed 3 different other ROM's (2 Sense and 1 Stock) and this still happens. I've asked before in the XDA LeeDrOiD thread and they said it could be related to backing up and restoring data whilst moving from Android 2.1 to 2.2.
What I have done this time though is not backup anything, no SMS, no system settings, nothing! I deleted everything off my SD Card, cleared the cache, then cleared the Dalvik cache, did a factory reset, Flashed the ROM and then Flashed the radio but still this problem exists, I haven't backed up anything this time, even created a new Google account so it didn't sync my contacts.
There's no particular website that does it, I've got the Flash setting to "On Demand", so that's not crashing it.
This is really starting to annoy me now but I can't figure out for the life of me why it happens, I've tried replicating it to narrow down the cause but I can make it happen one time doing it a certain way but then doing it that way again it'll be fine.
Has anyone got any ideas of how I can overcome this problem or how to Flash the ROM so that my browser will work correctly, this browser problem is the only problem I have with the ROM, apart from that it is superb.
To Flash the ROM I would do the following:
I go into the Recovery mode, wipe the Dalvik cache, then wipe the cache, do a Factory Reset and then Flash the Radio and then the ROM.
Isn't that supposed to completely wipe the phone and then anything Flashed from there is brand new, which is confusing if it is happening in different ROM's.
Also, the browser can crash whether I'm connected to a data plan/Wi-Fi or not!
Any help very much appreciated!
HTC Desire btw.

Anyone?
Someone must have an idea.

In a strange way that's good to know mate, at least it's not just me.
Hopefully there's a fix to this problem, finding the cause is hard enough though!

Well, I've managed to narrow it down as much as possible, seems to happen more when downloading from the Market or the Internet connection switches from 2g, H or to WiFi.
I personally think it has something to do with the cache, once it starts happening it happens alot, a restart later and it probably won't happen for most of the day, it's like something leaks and builds up and then crashes the browser with a restart resetting everything.
Anyone got any ideas?

[Q] HELP! My Incredible has frequent crashes and reboots

Can't find an answer to this on google or xda. Didn't know if I should post this in General or Q&A.
I have been using my Incredible since it came out. I quickly learned about rooting, roms, s-off... with no problems. I have been running Skyraider almost from the beginning.
Here is the problem: A few days ago, I noticed on the SR thread that there were updates for the radio and hboot. So, I went ahead and flashed them. Almost immediately I started noticing the screen becoming unresponsive. After a minute or two I did a battery pull, rebooted, and again after a little while, freeze and reboot. I also noticed that even when the phone is awake but screen off, it would wake itself up. The rebooting and freezing makes it impossible to use my phone.
I tried everything I could think of:
Nandroid restore (obviously didn't work since this doesn't effect hboot or radio).
Reinstalled fresh SR Rom wiping everything, including dalvik, and did factory reset.
Finally, I downgraded back to the hboot and radio versions I had before, still no effect. (Baseband version 2.15.00.07.28, hboot .79 ).
I tried installing another ROM (Uncommon sense) to make sure it wasn't a ROM issue, ..same problem.
Please, any help would be much appreciated. I don't know what my next step should be.

do you overclock at all?

No overclocking, I don't use setcpu, and I have been running the stock kernel. But it does feel like overclocking.

I wonder if the timing of events is just coincidence and its a hardware issue. I've had my Inc since June... rooted s -off in july and had no problems until about a month ago. I don't oc I use the new stock kernel but my phone hates change. Even flashing a small mod will cause rebooting.... and navigation always causes it. Phone heats up fast with these particular activities too but sometimes it will reboot at only 35c after a flash. I'm thinking hardware

Thanks,
You may be right.
For now things are working, let's hope they stay that way.

[Q] Random freezes and lag

I have some issues with my Defy, it worked great for about 5 weeks with Quarx's CM7 the i started to get random lags, all apps crashing and freezes. I wiped the cache and dalvik cache, still not working.
After that i installed MIUI, worked pretty good for 2 days then got the same problem. Wiping the cache didn't worked here either so i decided to re-install CM7 (7.1.0-jordan) but still got the same problem.
I tried lowering the CPU settings to the default but it had no effect.
What else can i do?
I'm kinda new to this so please, have mercy.
Thanks in advance!

Could it be the RAM (not enough available)? Use an app like this or similar and see if there's any difference.
Also, if you like CM7, go for CM7.2 - it already has a RC version, and it's stable and fast (bug fixes included, tweaks, interface optimizations, etc). Regarding the CPU: it's not necessary to underclock to the stock 800mhz value, just be careful about the voltages (don't go too low suddenly, or you'll get freezes or random soft restarts - try to undervolt progressively).
Plus, it's a good habit to wipe Cache and Dalvik cache before and after flashing a ROM/nightly.

it's not the ram, i used netqin from the beginning which has a widget that shows available memory and a task manager and the lowest memory i ever had was 100MB. currently on cm7.1 i have 213mb available.
is there a way to completely revert all changes, like a factory reset?

Actually, task managers on Android don't fix any problems, they even cause problems - I would get rid of that if I were you.
Like a factory reset? Wiping data from custom recovery (but you'll lose all data, settings, apps, etc on the phone), but you keep your current ROM.
Give CM7.2 a shot, it might be better.
Edit: Did you have these problems before installing that task manager?

i really don't care about the current ROM, i would go for the stock android just to have a working defy. do i need to flash a sbf before installing 7.2?
could it be a hardware problem?

Don't flash a SBF!
If you are already on CM7 just flash a CM7.2 version like a nightly (wipe Cache and Dalvik cache, before and after flashing). When I used CM7.2, I was happy with a version by maniac103, from 27 February. Stable, fast, good battery life.
If you really don't care about all of your settings and apps and data and so on, you could try to wipe Data in custom recovery before installing CM7.2, it might solve that issue (but I'm not sure, and it's not really worth it to try it now, only as a last solution). But if you do that, remember to flash gapps too, after the ROM.
But first try CM7.2 and use your phone for a while without that task manager.
No, I don't think that it's a hardware problem, especially if it worked fine after you flashed MIUI.

just installed cm7.2, will update if problem still occurs.
Thanks!

You're welcome.
Great, I hope you'll get rid of those issues. Did you also remove that task manager?

Yes, kept just the basic stuff for now. i have a problem with the proximity sensor, after a call the screen stays off and i have to remove the battery. I tried loosing the back screw and several ways of disabling the sensor but none worked.
Any ideas?

T-800 with Random reboots and battery all over the place.

Hi All,
My Tab S 10.5 is in a bad way. It was running a custom rom & kernel. However, it has been acting strange with random reboots and battery percentages all out of whack. It can go from 50ish percent to 80 percent, then back down to 8 percent.
So, I wiped everything in TWRP. (everything save ExtSD), wiped data and formatted data. Installed factory image from the thread in Android Development but the issue persists.
Is there something I'm missing or more that can be done?
Thank you!

Was it like this when you stock? I would guess it was the settings you had on when you had a custom kernal and ROM but since your in a factory image it might be your battery/tab s. Some people had problems with their battery and I think it was some sort of lose connector. Since Knox has been tripped I'm not sure if you can take it back. Try a factory reset perhaps? Hope this helps.

Don't overclock our undervolt anything in the first time when you are on a custom kernel. If you can work stable only change one parameter at a time so you can see when the tab gets unstable.
There is an app in the Playstore which has the name "BatteryCalibration". Maybe this helps you.

This only happens to me when i OC
