Captivate boots slow, issues. How to troubleshoot?

So, a little history...
I'm on my 2nd Captivate (unrelated issue). The boot problems didn't arise until I restored my data onto it. The first time I tried restoring system data along with my apps (which I figured was safe since I was going from 2.1 stock to the same) but that had lots of issues. So I did a factory reset, and started over. This time I just restored apps and their data, and a few specific pieces of system data (contacts, wifi APs, etc). That worked better. But later I got too aggressive with what system apps I "froze" (using Titanium Backup), and it got into boot loops I couldn't break out of. So I did another factory reset.
This time, first I carefully froze only apps I was to confirm were safe to freeze. I didn't proceed restoring my apps until I was done freezing and ensured it was booting fine. I then restored all my apps (and their data). The problem is now that it takes forever to boot... in fact, it'll go into a boot loop if I just leave it be. It seems the only way I can gain access is to try and unlock it before it's done booting, clear any "Force close" errors (sometimes takes a few tries) and given enough attempts, I can get in. But the boot takes an unbelievable amount of time, and even with my original apps is many times longer than before on my previous Captivate. Once I fuss my way in, it seems mostly fine, but something is obviously wrong and I want to get it straightened out.
Aside from doing another factory reset, and reinstalling all my apps (which takes like a day without troubleshooting after each, since batch restores in TB don't seem to work well on the Captivate so I have to do them one by one), I'm hoping there's a way to troubleshoot it in its current state and try to fix the problem surgically versus erasing and starting over. I looked at the logcat logs but got in over my head... there are so many errors and warnings and I don't know what's normal and what isn't... too many to know where to begin with searching Google.
So... advice? What tools are available? Even the logcat doesn't seem to kick in until the boot is mostly done, so I'm not sure if it can catch the problem while it's happening. One frustrating thing about Android is that is seems to have no "safe mode" or other diagnostic boot or full logging where you can methodically look at what's happening and experiment with the config. If this was a Windows, Linux or FreeBSD box I'd be in my element and able to get to the bottom of this, but on Android I feel even more crippled, locked-out and helpless than even on Windows. Urgh.
There's got to be a better way to troubleshoot and fix than endless random factory resets. This is something us anti-Windows people scold PC makers for, with all their use of "Restore CDs" for every minor and trivial software issue.
Thanks!

I can't help but think you are still disabling some essential system apps. Either that or one of your apps is causing major problems. Please list what you have frozen in tibu. Btw, the batch function works fine and is what most people on here use.
Also, what is force closing after you restore your apps.

First of all, thanks for taking a stab at this.
My frozen apps are:
* AllShare
* AT&T FamilyMap
* AT&T Hot Spots
* AT&T Maps
* AT&T Music
* AT&T Navigator
* AT&T Radio
* Daily Briefing
* Days
* Instant Messaging
* Media Hub
* Mini Diary
* Mobile Banking
* Mobile Video
* MobiTV
* Where
* Write and Go
* YPmobile
I also tried removing my MicroSD card, as well as switching back to Touchwiz (from LauncherPro). Didn't help.
Yeah the batch problem in TB is very frustrating. I'm using the pay/donate version so I'm missing out on a feature I paid for. I've been exchanging emails with Joel (the author) and we haven't figured it out yet. Batch backups work fine. Batch uninstalls also work fine (update: phone just spontaneously rebooted after about 50 or so uninstalls in a batch). It's the batch restores that seem to choke it. It's not corrupt backup files... a verify runs fine, and I can individually restore the same handful of apps one by one that will choke and hang/reboot the Captivate if attempted to restore in a batch.
The FC error I get is on boot-up, as I try to unlock the screen prior to the boot finishing. I often see "Process system is not responding".
I have aLogcat installed, if that's any use. A few questions about that:
- What's the best logging level to view on? In other words, do I care about "Warnings"?
- What errors are common, harmless, and safe to ignore?
Currently I've tried uninstalling everything down to just a few core apps. Certainly boots fine now, but I get plenty of warnings and errors in logcat.

Are u restoring just the user installed apps+data, or system apps too? Or restoring system stuff like contacts data, accounts prefs, etc?

I did not do a "restore system data" or any batch/bulk option in TB that restored all system data. As I recall, the only system data I restored a-la-carte (by selecting the individual item from the TB list) were:
Accounts
Bluetooth pairints
Bookmarks
Calendar
Contacts
Wi-Fi Access Points
These were all items in green in TB. I don't believe I restored anything else. Possibilities I suppose are wallpaper settings, "Country, Launguage, Time Zone"... but I definitely would not have restored anything not green.
Are these items safe? Is there any system data definitely not safe to restore? I have to wonder though, if "system data" is unsafe to even restore to the same stock OS version... why back it up at all?
I'm not a long distance from doing yet another factory reset I suppose, if it must come to that. But I'd love a way a bit more analytical/exacting to try and troubleshoot this other than "reinstall one app, reboot, see what happens" as that will take me a week to get back to where I was. I also suspect it's not just one single app that would suddenly show a huge difference after installing, but instead might be the cumulative errors from several apps and knowing how to identify that and clean them up would be useful.

Using adb logcat you can view what is occurring while the phone is booting and possibly see where it is hanging or what is causing the slow boot times. I have seen problems from restoring data such as accounts and contacts with titanium backup but does not seem that it should be an issue when using the same system though I have very little experience with the stock firmware. I know it is not an answer to your question but it seems that you are wanting to remove all the att/Samsung BS so why not flash a rom that does this as well as much more?
Sent from my ADR6300 using XDA App

Thanks for the tip about adb. I've actually not needed adb for anything yet so I've never set it up or used it. I wasn't aware that the service would be active early enough on the phone's boot process to allow it to log boot logs... nor was I even aware it could do this. I'll definitely check out how to set this up... however, if you have a free second and can point me in the right direction (FAQ, instructions, etc) it'd certainly be appreciated otherwise I'll search around and try to find it.
I could probably find other ways to restore contacts and could set my accounts up again manually but I really doubt that's the cause and the other ways are sort of a pain and imperfect. Since neither of us is really convinced that'd be it I won't bother yet until/unless you really suspect it.
I wondered how long it'd take before someone would suggest a custom ROM, this being XDA and all. Short version is I'm not really sold on the concept, as they are all based on the buggy beta leaked ROM, or 2.2 ROMs from other devices that have been hacked up to sort of work as well as possible on the Captivate. All seem to have issues... enough that I'm not really left feeling confident about them. Seems every release unleashes new issues despite addressing old ones, and all seem to have at least a handful of gremlin items that just don't work quite right. Don't have a warm fuzzy feeling, and I still feel like Samsung is going to release an official 2.2 for the Captivate within the next month or so, so I'm interested to see what comes of that. If nothing else, it'll give a better baseline for custom 2.2 ROMs. Then there's the 2.3 being worked on... now that might be interesting.
I don't really think my issue here is related to me running 2.1.

On my phone so it is a pita to search and add a link for you but search for android sdk and you will find what you need to get adb up and running.
And as far as the rom issue goes..it is your phone and I respect your concerns I just had to ask

I would think its media hub that slows it down. It will search your SD cards on every boot. I would start there first.

That's one of the apps I've frozen though.

For me the longest process while booting is the stupid media scanner upon bootup. Takes FOREVER for the phone to finally "boot" all the way up.
Been looking for a way to disable it (not really lol) and only have it scan manually to see if the boot time will improve. I'd start searching there.
Also - from what I've read nothing you did should have affected the phone. BUT - if your using Google for your Calendar and Contacts.. and they all get synced up to Google? Why bother doing the restore for those? After you sign up with the Market they get pulled back down to your phone automagically

It's definitely more than just the media scanner. I watch that. When everything is loaded up, it actually reboots in a loop unless intercept the FC. The media scanner will rerun over and over each time... far more than the standard two times.
And I use Google Calendar for my events, but I keep my contacts locally on my phone.

So what is the FC again?
Yep.. my media scanner will run at least 3 times before it stops checking everything.
Very frustrating that the software does this EVERY time I boot back into my phone - you'd think a programmer would put a check to see if it had run before or make it user configurable to scan when you want it to.

See my second post (reply #3):
"Process system is not responding"

LOL sorry not enough coffee and a lil' guy that decided to wake up at 4a.m. = not a good mix.
Well.. did the ol' wise search of Google and came up with:
Might be a permissions issue. Easiest way to fix it is to run ROM Manager and have it fix permisions.
Run the command yourself in ADB:
Code:
Open terminal and
>su
$mount -a
$fix_permissions -r
The -r is optional, but necessary if you find orphaned apps (the app not found please reinstall message)
And reboot. That may help.
And it was also stated that you might have an errant widget/application causing the issue as well. That will be fun trying to figure out what it is.

And.. from my non-dev/non-professional experience - I have checked the logs on my phone and do see a large number of warnings on the phone - but never hindered performance.
So.. 99% of the time you can probably ignore them.
But back to the FC issue - I would try doing a restore of your apps/data again (I read where you have it back down to the "core) and then run the permission script or have ROM Manager do it for you and see if it returns.

Just an update that I think the "fix permissions" thing solved most (but perhaps not all) of my issues. Thanks so much for the tip. I've been reinstalling apps in batches and it's much better, although I see it getting bogged-down bit by bit and I can't pin down what or why.
Thing is, the apps I'm installing in these later rounds/batches shouldn't be resident all the time, shouldn't be auto-loading, and don't come up in things like Startup Cleaner or Advanced Task Killer. Nor do the various process monitors I've tried seem to have the granularity/ability to catch them while they're happening.
So things are better, but I still have some issues without a suitable means to diagnose. I don't get why just having more apps installed, but not running, should affect boot time so much. Hmm...
An inability to troubleshoot certainly rains on my love-affair with Android... not that I'm jumping to another platform anytime soon, but I really want this to work well (as well as be a good salesman to friends and family who often turn to me to show off quality technology).

[Q] What Bloatware have you frozen/uninstalled without incident?

On my LG Revolution My SystemPanel App shows about 350 MB memory and 12 GB on the SD card. It also cites System Storage 1 GB, Application Storage 1.5 GB and Cache 193 MB. The SuperBox app shows 1.5 GB "Phone" memory. With about 25 applications "active" and several widgets installed, I still have 134 MB memory left
So far I've found the battery life not great, definitely have to charge during the day with 4lte and wifi on.
Noticed a bunch of the bloatware widgets took up memory even when I deleted them from the homescreen. Used TitaniumBackup to Freeze
Apps I've frozen with no apparent problems (yet).

Ya, coming from the incredible, even stock I would have 100-150 mbs of ram, and rooted I'd have usually 180-210. This phone, having the same amount of ram as that, will be anywhere from 30-100 usually. That's some pretty bad bloat.
In 3g only network, the phone actually has a really good battery(compared to the incredible), I can go all day without root so far, the baddest part is the % i lose just sitting there without use and the screen off, it sucks.
And have you been able to assign Google where Bing had priority before? I have the bing search relatively good, just really laggy.

Thanks for this list! I had started to experiment but kept it on the safe side since we don't have a recovery yet.
I noticed that there is quite a bit more listed in Bloat Freezer over Titanium which was my first freeze app. I tried Bloat Freezer when I noticed that some things that were frozen were still showing running processes.
A couple of notes to add on to this -- I'm running Go Launcher and cannot use any of the LG specific widgets, Friends+, What's New, etc. but:
What's New is still running and has functionality beyond the What's New widget. I forget the details but I think on a missed call I got the What's New app to display missed call, sms and email count from the pull down alerts. It was late and I didn't think twice about it until the next day (which is what prompted me to find out what was still running in the background even though I'm using Go Launcher.
I'm not sure exactly which Verizon app is responsible, but i recently unfroze all Verizon specific apps while experimenting and I was prompted to try the new data usage widget from Verizon. When I originally froze all these apps, that widget had stopped working in stock home. So it is not dependent on your home/launcher, but it is dependent on one of the VZ apps.
I'm tempted to just go down your list and freeze everything all at once, but maybe I'll do it in small batches and report back any findings.
Again, thanks for the list!

Wow, that is a ton of frozen bloatpops... didn't think too much of it but that's more apps than i had on my Inc. total on CM.. lol.

I have them frozen and already recieved an SMS, so no hindrance there. I recognize the SNS icon from when I first got the phone (one of the widgets I think). I can't see any effect of having them frozen other than the obvious of course.

Be careful with these, I used Bloat Freezer to freeze a small subset of the apps listed in this thread (and none others) and now don't have a home screen. I turn on the phone, slide to unlock, and then the screen is black (normal indicator icons at the top). Holding home gets me to a recent apps page with no recent apps. Nothing else does anything, I can't even turn off the phone without taking the battery out. Any ideas?

the ones i posted can be frozen with no incident.
of course i use a custom launcher (launcher pro) so i can't attest to the home screen working
however, after freezing some other apps listed in other posts my bluetooth wouldn't work...

I use Go Launcher and I was able to add a few to the lists above:
Tunewiki
Sync Service
Mobile IM
Messaging Widget
Messaging (I use GO SMS)
Does anyone know what the LG and Verizon hidden menus processes are?
System seems a lot faster now and has better battery as far as I can tell.
Only issue I can think of, is that When I have my BT earpiece on and connected, I can not seem to get music out of the 3.5mm jack and into the car's aux.
Anyone else have this problem? What is the solution?

What wifi tether is everyone using? My market won't update. So if anyone can post an apk that'd be great.
Also don't freeze autorun 1.0 i think it is. That is the connectivity option for our usb and hdmi slots. Without that it'll work but you can't change the options ever. So you'll be stuck with hdmi off or on and usb charge only cause i think it always starts as.

OP:...just a thought, take it or leave it haha
It would be greatly appreciated if you could update the list every so often with new ones added throughout the thread. Then maybe this could become a sticky at some point.
Also:
Anyone else realize Latitude and Twitter for LG doesnt show up in Ti Backup yet is running every once in awhile.... or maybe it's just my phone?

Um I don't even remember twitter being on my phone, I use bloatfreezer and pretty much froze everything on the OP list. I don't think there is to much else that you want to freeze with out risking your phone

If you use the stock launcher and then freeze Home 2.2.2 then you will have no home screen.
I use Go launcher EX so I was able to freeze home with no problems.
Only thing I can think of is a factory reset. But I'm sure others have better ideas.

I don't think Twitter for LG (or anything for LG) is active without the LG Home active.

I left lg home active, twitter doesn't show up anywhere in bloatfreezer. I have nothing on my phone that even refers to twitter.

Yea i'm not really sure where it's at. I think it's a sub-app(?) of something like one of those facebook/twitter/etc feed widgets. But every so often it shows up in my "running" folder on Go Launcher EX, and I used to see it in my task killer when I had one but i've never seen it on a list anywhere else.
rogue bloat? a new age in ruining our phones haha
As major said, and from what i've seen he's right 99% of the time, I haven't seen it since I froze/.bak LG Home. I'll post a screen shot if I end up seeing it again though

is there a reason that we can not just delete the .apk files from /system/app?

we're pretty much able to do that....but the hesitation has been because we have not had a recovery system and it's risky to start deleting any files at all.
However....a recovery system has been through testing lately(yesterday/today) and was released. There's no saying it's perfect but I haven't heard of anyone having big issues. So if you are comfortable with the recovery system available, delete away.

Hopefully you have this fixed already if not:
not sure if this will work but...connect your phone as a USB and hope it connects as a Mass Storage. Go into data/app and delete the Titanium Backup .apk
No idea if this will work, but it's possible that with TiBackup gone it will unfreeze everything.

Frozen DLNA was still running

So after rooting I froze a bunch of bloat with Titanium Backup, including DLNA and the DLNA service.
Just noticed this morning that DLNA was still running in the background, about 10 reboots after freezing it. Ti still showed it frozen, but it was definitely active and running. I unfroze it and used root explorer to rename it to dlna.bak, and it immediately FC'd, and I rebooted, and now it's not running, and all is good.
But how is it possible for a frozen app to run itself??

It's being invoked as a library from other processes. I've mentioned this a bunch of times before, but there's lots of processes that are acting this way... Task Manager, World Clock, etc.
I have a bloat removal (and restore) script here:
http://forum.xda-developers.com/showthread.php?t=1238472
It will rename the packages to .bak and then rename back when you undo. Has prompts so you can choose what to keep and what not to keep, etc. I recommend using it to remove bloat instead of trying to freeze.

I'm seeing a general concensus that renaming the apps instead of freezing them is the way to go. I've had luck with this as well with psouza4's script.

Video recording not working after root.

I just finished rooting my girlfriend's G4. Everything went well, but for some reason, video recording does not work on any app. On the stock LG camera, I get "An error occurred" as soon as I press the record button.
Doesn't work on snapchat, or on Google Camera either, but can take pictures just fine on everything.
One thing I noticed is that something called "com.tmobile.pr.adapt" was asking for root permission.
If anyone can help, please do. If not, i'll have to just unroot her phone.

There are not many people complaining about this issue, but I a have come across a few posts asking for help with no responses
From what I can determine the issue revolves around the driver/kernel module providing access to the hardware accelerated video encoder/decoder. This could mean something in a configuration file, or the driver is not getting loaded, maybe even some missing .so files, but I haven't figured anything out yet. I do know that all the apps I have that fail rely on the hardware encoder/decoder (LG Camera, Tivo, Plex). Some apps like Youtube, and MLB At Bat play video without error, I believe these applications to use software decoders for thier video.
I spent some time poking around the file system, and looked at a few files / packages of interest.
build.prop - this file had some flags around video and drm, I checked against a copy online and it appears to have no difference.
com.lge.divx.permission, com.lge.divx, com.lge.drm - could be suspect i poked around their files and did a reinstall of them but there was nothing obvious and the reinstall made no change in behaviour.
LG Video, LG Camera - These applications both failed to be reinstalled from their .apks in /system/priv-app/, when the LG Camera app failed to be reinstalled, the application failed to later run until after a reboot. I was hoping that either of these applications would cause a reconfiguration / re-installation of the drivers.
I viewed the dmesg and logcat output in an attempt to see if there were some system errors when the apps were run, however this yielded nothing useful for me.
I wanted to try running ldd on these applications, to see if all the dynamic libs are found, however since I don't know too much about Andrioid I am not sure where the binaries are stored for say the LG Camera app, so I haven't been able to do that yet.
Luckily im on T-Mobile and can flash a rooted MM, but I will try to get to the bottom of the issue if I can.
I would be happy for any one who can give me tips or suggestions.

I noticed this too, this appears to be a system for tmobile's techsupport to tell if a mobile has been rooted, I blocked it from root in SuperSU, and froze the app using TitaniumBackup. I suspect this has nothing to do with the problems with video recording or playback.

I wonder if it's people flashing the wrong kernel when they root. It would help to know what method was used to root.

Thanks for the reply.
I followed the video tutorial at http://www.xda-developers.com/how-to-root-the-lg-g4-and-install-twrp-recovery-xda-tv/ to root my phone and pulled the images for the tmobile from http://forum.xda-developers.com/g4/...-tmo-vzw-intl-variants-soon-root-lg-t3164765/
At the time I was running the latest lolipop 5.1
I would have thought if I dd'd the wrong image I would have more problems then just the video issues. Though I did have to do a factory reset since many of my apps (System.UI and Google Play Services) were crashing constantly making the phone unusable. Once the factory reset was done it was good except when i later discovered the video issues.

Deleting Bloatware

Hi Guy's/Girl's,
So i just successfully rooted my device with SuperSu and I'm looking to delete some bloatware, I've read good things about Titanium so i thought i'd give it a go. I'm mainly just removing all the stuff i don't use on this Tab to speed it up as all im doing with it is playing Mobile Legends and browsing, I've noticed that after removing app's their icon is still viewable in the draw but when i click on it nothing happens.. Does this mean that the app has been successfully removed and i just need to hide the icon?
I was also wondering would i be able to delete TouchWiz if im using another launcher (NOVA Launcher) or will it bug out?
Thanks in advance,
Cheers.

I generally freeze things in Titanium initially. Then, if no problems crop up after a reasonable time, I'll go back in an uninstall. If problems *do* crop up, I can thaw the app with (hopefully) no harm done.
That said, I've left TouchWiz alone since it is tied fairly tightly to the whole OS (and yes, I do use Nova).
