[Q] Data corruption upon clearing cache/Dalvik?

First off, i always do a nandroid backup before flashing a theme or ROM.. which usually saves me.
I've noticed recently that, pretty much every time I clear the cache 3 times, then clear Dalvik 3 times, (in clockwork 3), after flashing anything, upon reboot, i get the boot animation, then vibrate, then double vibrate > bootloop.
This seems to happen even if I don't flash anything following the cache clear. Has anyone else had this experience? I'm more interested in the cause of this. I've since restored everything manually, but I'm a total flash/pushaholic, and looking for ways to avoid this situation. Any help is appreciated.

Did you properly shut your phone down prior to the cache wipe? As in power off then wait for the vibrate to signal it shut off.

Why are you clearing cache and dalvik 3 times after flashing? Once should be plenty sufficient..
As for the cause, I would assume its the dalvik clearing.. cache is its own partition, where the dalvik is is on the system partition, and you are probably corrupting it with excessive writes..

Also remember that the version of CWM 3 we run on the Epic currently is not official. It can be a PITA sometimes. Dameon has done an awesome job porting it so we can have ext4, but I'm hoping some of these issues get cleaned up when we have the official version.

Hm, I almost never do that, but I will start. I usually do the death grip, then reverse death grip into recovery. (Can i trademark that name?)
@Mattalica: also good to know I'm not totally alone on this. I hadn't considered that. Thk God for nandroid + unyaffs
@Chris41g: i was trying the cache wipes on their own just to try to isolate the issue.
Thx everyone for feedback.

If your phone is running a "no-journaling" Rom that will cause corruption.

No journaling alone will not corrupt data. You have to shut down improperly or have a lockup caused by an unstable App (like beta wireless tether) or an unstable overclock/undervolt.

Yep, I know you know what your talkin about. I just didn't want decalex to take your response out of context, as some have been stating that the lack of journaling by itself causes corruption.

Is the vibrate, then double vibrate during the boot animation (then loop) indicative of "data corruption" ?
Next time it happens, I'll try to logcat.. I'm curious what is actually happening .. unless one of you already knows.

[Q] Issue after ICS update - Phone freezing

After the ICS update on my non-rooted phone, the phone seems to be freezing
up and becoming unresponsive. After a while it looks like the radio "resets", all
the icons disappear in the top bar (signal, wifi, data) and it shows no service.
Then slowly one by one they all come back and I can use the phone again.
Sometimes I receive the "System is not responding" dialog box, but not always.
There is not one particular program it is doing this in, it can be something as
simple as pulling down the notification bar that will cause the freeze.
Any suggestions are appreciated, I couldn't find anyone else with the same issue.
Thanks.

Try:
Turn off phone
Take out SIM
Put SIM back
Turn on
I've had my phone act weird with respect to signal, wifi and data when this was the issue. Worth a shot, at the very least.

Thank you for the response.
Tried this and had the system is unresponsive issue right on reboot. If I do a
factory reset, does it reset to the current firmware or what was originally on the
phone (probably a really stupid question). I wonder if some other program isn't
ICS compatible and is doing something in the background. Doesn't look like
anyone else is having this same issue.

If you do a factory reset and it was the standard Kies legit update from Tmo, it won't downgrade your phone - will just re-install a fresh copy of your ICS. Did you do a restore of apps from your last version (gb?) with data? That could cause problems I would think..

Yes I did the legit update on Kies, standard stock phone un-rooted.
Do I need to backup pictures before the reset, its been a while since
I had to do this.
At this point, I think its worth a try to wipe it clean and clear out all the
data.

wipe the dalvik cache and cache then reboot

I did a factory reset and that solved the issue.
Thanks for all the assistance.

I've done a factory reset and wiped the cache more than once already and i still get a force close or unresponsive, enough that its really irritating me now. Any advice? And also, when texting, the typing responds very slow.

Are you letting it sit for like 10 minutes during first boot after factory reset then reboot again before setting up. Its likely that some scripts are running from the initial installation and you need to let it rot until its done..

I did exactly that, thanks for the advice. Hoping that may fix the problem. I wiped the cache and factory reset, then let the phone sit for a good while before going through the play store and re-installing everything.

This issue just resurfaced again. The last 2 days I am getting the freezing, radio reboot and android process not responding.
No one else having this issue?

I think I'm in the same boat. I was stock GB, and just did the mini OTA update (which was great). A few days later ICS became available via Kies from T-Mobile, and I "upgraded".
Since the upgrade my phone is laggy, screen is significantly less responsive and also my battery life is less than before.
I have NOT done a factory reset of my phone yes (plan on doing that today), but even with that I have read that performance does not improve.
Ideally, I would love to return back to the stock tmobile gb firmware. However, even after literally 2 hours of reading I can't find the "how-to" and files I need.
I would appreciate any assistance.

t989 chip lags
ive notice this happen on my tmobile galaxy s2. i think it has to do with the Qualcomm chip on tmobiles stock roms.
When i had sprint i bought my girlfriend a galaxy s2 on the sprint network which runs the samsung exynos chip. She never complained about any lag or freezing whatsoever. I then left sprint because of their garbage network and joined tmobile.
bought 2 galaxy s2s and i noticed the lag almost immediately. The phone has random lag spikes as well as freezing and force closes. It had it on stock gingerbread and it has it on stock ICS too.
My girlfriend complains about freezing all the time so i decided to root her phone too. Right now im testing DarkSides v7 rom and if its pretty good in performance i will flash her phone with it too. So far it has been pretty snappy and everything works.

Because you are on stock ics (im guessing you are..), you can just follow that guide and flash the UVLDE update.

Yes clock resets to standard standard time.. I already did a factory reset and worked done for a couple weeks. My wife has same phone and she is getting the freeze ups now.

[Q] Weird behavior with Cut and Paste ROM

About a month ago I downloaded and installed the latest Cut&Paste ROM.
Really like the battery life. Been working well but recently it the phone started to randomly reboot and now I am seeing something really weird. The whole screen looks, I guess you would say over exposed. Like it is glowing or something.
I rebooted a few times and it went back to normal, but now I try to restart the launcher (using Halo) or reboot, shut down, take out the battery when it comes up again I am still getting that strange coloring.
Has anyone seen this before?
Looks like there is a new update to Cut&Paste. Maybe try that?

Please post questions in Q&A
Thank you

yeah try the update, but clear /cache and dalvik or factory reset before you flash a new or updated rom.

Turns out I already had the v2.61 Extra Crispy version. I did wipe everything and cleared the caches, reinstalled the rom and I am seeing the same thing.
Even when I was on the clockwork recovery screen I was seeing the strange coloration/over exposure.
I am thinking it must be the phone itself. Probably on its last legs. Have people bought new Epic 4G phones or just moved on to a newer one?

[Q] Why my gnex slows down instantly after 1-2 weeks of usage?

last month i bought gnex. i used stock rom for 10 days. then instantly phone slowed down after i add my musics..i thought that is is about rom then installed pa rom. first it was great but now after two weeks it started to slow down very much. for example a message thread that have just 2 message is being deleted in 5-6seconds..phone shuts down or boots to slow. i dont get it why this happens :/ any solutions or ideas??

You have lots of apps running in the background. Check what is starting at boot and constantly running. You also can overclock your device for faster game loading and scrolling.

I have been using rasbean pretty religiously since porting it for the sprint nexus. I haven't had any slow downs in fact its stayed as fast as it was when I first flashed the ROM clean. Which for me is weird because on other ROMs I always had a slow down after a couple weeks. But not the case on rasbean. I suggest you try it with trinity kernel. Its a stock ROM with hand coded options.

I can almost confirm that:
Bought a new, 4.1.1 Nexus - everything fine
Flashed AOKP, restored some apps with Titanium and filled it with stuff - slow
Flashed CM10 & MIUI - slow
Deleted everything, flashe CM10 and left 3.1GB free - everything fine
In between I also flashed franco and trinity kernels, tried deactivating 5GHz Wifi, tried not restoring with Titanium, deleted many files and maybe other things that I don't remember about.
Looks like you don't have to ever go below 3GB free.

yes, rebooted every 3-4 days. i really don't understand. stock rom was slowed down after I copied my musics about 10 gigs. and now on pa rom slowed down after i downloaded 5-6 mp3 from internet. all I have was 10-15 songs on the phone. and 2 movies about 8-9gb. i always watch movies and delete. after slowed down i removed movies, songs and also google music app but nothing changed.i also flashed a lag fix from somewhere i dont remember but again slow slowslowww now i tried to wipe cache, dalvic cache but nothing changed... when i tap facebook it hangs for 10 seconds and says not responding close app? i say wait and then it opens...

I have the same problem... Slooow as hell, apps FCs and not responding... Problem even stays after flashing other ROMs and stuff... I hope a factory reset will just do it...

So do you all recommend what is discussed in the link you posted or overclocking which one works better? If overclocking what speeds so you recommend?

GNex lagging really bad after using it for a few weeks.

I had this problem before a few weeks ago, but a full boot.img stock reversion fixed things and I unrooted (then re-rooted) and installed the PACman ROM with the AK Kernel. Everything was fine until a few weeks later it started to lag really bad again. I'm talking the screen would hang for 5-10 seconds or just freeze completely. Earlier today I had to pull my battery about 3 times because of the freezes. I tried to install a new kernel a week ago, but that made it worse.
Why does it keep doing thing. I love the custom ROMs and the kernel tweaks, but I won't be able to use them if I go to stock...

Same thing here on complete stock 4.2.2
Been doing factory reset once a month since I got the phone in September.

You interpreted the symptoms yourself rather than just report the issue and what software combination is resulting in the issue. Its lagging but why is it lagging? "Lag" isn't a symptom its a result of something else going on deeper down.

Diagnosing problems you don't understand is exactly the kind of thing that makes it impossible to help someone. The phone may be right in front of you and you may know what you did but so far all you've done is tell us that:
1. Your phone lags
2. You tried a different kernel
3. You've pulled the battery
Not much to work with is it?
What CPU settings are you using?
What superuser apps?
Etc.

I don't know. Turning the phone on takes about 3 seconds, same with turning it off. After unlocking, it hangs for about 4 seconds. Opening Chrome takes 5-10 seconds. Pressing the home button while on any app takes 5 seconds before it gives a response.
Don't say those are regular waiting times either, before I had these problems, things would appear at the touch of a button.
I also forgot to mention that a fresh ROM install doesn't help.

I think that space is an issue. I've read that once you get below 3 or 4 gigs free, the lag begins. Supposedly, on any disk, you should keep about 20% free, which for a 16gb gnex is 3.2gig.
Edit: isn't 180ghz min pretty low? I've seen 384 as a min suggested if lagging is an issue. And i think you mean mhz.

This is why they shouldn't have gotten rid of SD cards...
I'll see if clearing out my HDD space does anything. I've had it that full for quite some time though...
I'll see if putting 384 as min fizes it.

Your device also might not be able to handle 1.4 GHz oc. While its originally a 1.5ghz processor mild imperfections in the manufacturing process result in it being sold as a (guaranteed safe at) 1.2ghz processor.
What that means is that not every phone will handle the same speeds, voltages etc. You should try running at stock speeds for testing purposes.

I have this same issue, I've tried a number of different ROMs and kernals. They all start out great, then after about a month my phone starts to get random lag, then as time goes on it gets worse and worse until I bite the bullet and start over again
