Captivate Random Shut Downs Solved (kinda)

DO NOT RUN Advance Task Killer period. It does nothing but cause problems for the phone on eclair. Google recognized this and added a task managment solution built into froyo that works much better and won't cause random BS. If you think you know how to run ATK then you probably don't so read up on exactly what it does. Just remember people, when you boot up the phone, it starts most of these services because they are essential to the phone operating properly... imagine that. Don't try to be smarter than the phone. You are not going to save battery by removing processes out of memory. Period. Let them run. If you wanna save alot of battery, turn your display off automatic and run at a lower brightness level and turn your 3G radio off when not using data. Its that simple.
As for the speaker problem, remove the back and battery off the phoen and with your trigger or fore finger aggressively tap 1 time on the speaker grill and your sound should work when you boot the phone up. This action could be described as thumping the grill with your finger. I know this is a caveman way to repair a phone and is closely related to the beavis and butthead "kicking method" but it works almost every time.
Hope this thread helps. Your comments are very welcomed. Tell me what you are thinking....

Thanks for the info. I use ATK, but not in a harmful way (haven't experienced issues or random shutdowns). I have an extensive ignore list (of things that need to stay open) and security set to high, so system processes won't even show up, so it's impossible for me to kill them.

BTW... Just to qualify myself a bit. I am samsung certified and I am running a Captivate on the Leaked froyo, rooted, sideloaded, overclocked to 1.2ghz, verizon market fingerprint build.prop mod, LCD density mod = 210, startup sound mod, battery percentage in task bar.

well thanks for the inside scoop. so we can expect a major OTA update around christmas for the US market?
i will be removing my ATK program today. I've also been using Captivate Keep Alive, which apparently opens up a ton of applications to keep your phone active and prevent it from entering that "comatose" state i think.

Thanks for the info!
Can you recommend another easy way, besides ATK, to shut down all of the unwanted AT&T programs that load during startup?

Great info, thanks!

Hope you are right, but software issue is hard to explain my case. The first one I got had shut down 4 times within a hour(worst case, usually 2 or 3 times a day), and the replacement been used about 2 months, never had an unexpected shut down. Both of them are unroot, no side-loading, and never use ATK.

danalo1979, since you have the inside scoop, will there be any GPS improvements, or is it as good as it will ever get?
Thanks for the info on the speaker problem. I just had my phone swapped out for this problem. I wish the person I called into at AT&T would have told me about the Cave Man method.

Thanks for the interesting information.

Root your phone, get root explorer, go to system>app> go to desired apk file that you want to disable and rename to.bak extension and the os wont recognize the program. Its reversable just rename back to apk. Reboot phone. Don't do this on anything that is required for the phone to run.

So the random shutdown is only an issue for eclair roms? Kinda explains why I haven't had any shutdowns since flashing cognition.
Also, I find it kinda funny that an AT&T employee has his captivate sideloaded (no offense! Just wondering why AT&T would even want to block sideloading apk's..)
And the ETA for the OTA sounds very disappointing.... late Dec~late Feb...

Just had a shutdown, running Cognition 2.3b4. Have had other shutdowns while on Cognition.

I've been on 2.2 of some sort since it leaked. Mine has shutdown as often as 3 times in a day. from 100 to 50% battery charge. There is no ryme or reason that I can identify except: While running system panel; When you look at the graphs for the time period that a shutdown occurs I notice that the battery charge graph will suddenly drop like a rock, like 50% of what's left and then when i turn it on it initially reports the lower amount but by the time it boots it shows a "correct" representation of the battery charge. THAT is consistent for every shutdown. Sudden drop (50%ish) and it reports low on startup and jumps just the same.

Random shutdowns on Froyo but not Eclair
Well I'm on my second captivate, first one random shutdowns from day one.
I have gone months with no shutdown while running stock Eclair. The day I flashed the leaked Froyo or Cog I recieve random shuts within a few hours. I tried flashing back to stock/master clear/ battery stats all with the same results
For me with stock Eclair no random shutdowns
with Leaked Froyo or Cog I get random shutdown within a few hours
Frustrating

So are you able to restore to a point that does not produce shutdowns? If so, what method of restore?

Flash Stock J6 from here:
http://forum.xda-developers.com/showthread.php?t=731989
after going back to stock 2.1 no shutdowns for over 2 weeks.
Last week flashed cog 2.3B6 couldn't take being on 2.1 anymore....shutdown within a few hours, installed CPU tuner and no shutdowns for 5 days so far running cog 2.3b6
If I had one shutdown running stock 2.1 I would return it

Dear OP, first off, I believe what who you say you are and what you wrote. Thank you for being open and honest. I am bone stock ATT 1010 v.004 phone build with a 09-17-2010 battery. When phone is completely stock it does not shutdown overnight. As soon as I add an APP, I get the overnight shutdown regardless of battery condition. I see that many apps say they need access the power keep alive function of the OS. Now I am not running homebrew apps or any mods as mentioned. I tried basics like Kindle or eBay or Chase Bank. I am 7 days into my phone and need it to stay on, so I can use the alarm etc. What do you recommend I do? Just keep returning it so I stay inside my 30-day window? Jump to a WM Samsung? iPhone4?
Can you also PUSH PUSH PUSH ATT to get this corrected. Samsung and ATT did not publicly acknowledge the problem on the three times I called, but only said if I returned the phone and got a new one, I would NOT have the problem again. Why is that? What do they know?
Thanks!

No offense to OP, but both Samsung and AT&T know how to lie quite well. Especially if it serves to screw you so they get more money.

Is it safe to freeze media room?

id like to freeze It since it always seems to be on and running at leasttwo processes, despite it never being used, at all. im just wondering if thats safe at all, especially since media scanner seems to be a part of it. Is that important at all? I dont remeber it being on my old lg Ally.
I already froze drive smart and media hub due to their constantky being running despite literally never being used. I think ive been having some glitches due to drive smart being frozen though.

Doesn't hurt to try. Give it a whirl and post your findings.
I doubt it'll do any real damage.

NO! Do not do this. Tried it out of curiosity and now my phone just keeps vibrating and blank screen after the boot animation.

What else did you freeze?
Freezing Media Room hasn't caused me any issues whatsoever.
Leave the media storage service alone.. just freeze the Media Room app.
I suggest replacing the Media Room with PowerAmp and Vplayer.. then freeze it and forget about it.

Yeah dude I froze some stuff on my phone last night while I was drunk. Same issue boots and black screen with alot of vibration. How can I unfreeze apps in adb. I detect adb in recovery not when rom is booted.

[Q] Dangers of Battery Pull Shutdowns (Quick Boot)

What are the dangers and issues you could face from shutdowns like Quick Boot or battery pulls?
Currently, the ROM I'm on has an iffy shutdown so I use Quick Boot to bypass it but I just want to know what risks could come from it.
Thanks.
Sent from my Nexus S 4G using xda premium

The risks are minimal. I wouldn't worry about it unless you're pulling the battery several times a day... An app like Quick Boot doesn't do anything bad. All it does is effectively run a command to reboot the phone just like you would with ADB from a computer. There's nothing wrong with that.
What ROM do you have that won't shut down properly? Doesn't sound like a very stable ROM.

stumbled into here after using quickboot for the first time. wondering if you have run into any problems using quickboot to go directly into recovery.

[Q] Anyone had their phone restart and erase itself?

I was using the Facebook app yesterday when it locked up my phone. It was still on, but it didn't respond. I had to pull the battery, but when I turned on the phone, all my data on the phone was wiped.
The phone immediately started to FC. Smart Keyboard, Go Launcher, etc. It brought me to the screen to add my Google account.
I was wondering if this has ever happened to anyone. I found it really annoying that it happened on the one day when I needed the phone at most and even fixing permissions didn't work. Reflashing the ROM was a temporary solution as the stock SMS app kept on crashing (no idea how that happened). In the end I decided to go back to stock + root.

Yes I have. Only one time about two weeks ago.
Have no idea why. Was not tinkering. Had not changed/added apps or other around the time it happened. Just went to look at it and it had factory reset itself.
When it happened I was on VB, LZ, AntonX first BLN kernel and undervolted with DSexton's values.

I had it happen once a few months ago. I rebooted and when it powered up it went to the setup screen and was just like I factory reset it. I was on icbinb.

Ive had similar things happen. Two days ago my phone went nuts after a app updated. Not sure which one did it I had several that were showing updates.
Logsprovider and another that I dont remember were continuosly force closing. I booted into recovery, used the recovery file manager renamed the two apps as .bak, rebooted the system. Backed up texts and calls then reinstalled the rom.

Did any of you do a full cwm restore prior to this? Had any of you been experiencing random reboots prior to this? I know a couple of you started what ROM, but lumin started what kernel and tweaks he had. Can the rest of you provide that info? I'm looking for a commonality add i have experienced this as well once upon a time. I was on vb, lightning zap, and Brians kj6 rc2 when it happened to me. Now I'm on miui with Antonx test 3 kernel and I'm getting random soft reboots with the phone freezing up before hand. It might be an app issue though. But let's look at the basics first.
Sent from my BAMF SGH-T959V!

it's happened, but only when I was on KF2, back in the early GB Leak days.
The rom was really unstable.
Also, I had modded

thomas for me I was on VB-FB using the latest antonx kernel. I dont remember using any tweaks other than what is in the rom.
I was getting soft reboots until I removed bln. I think my problem was related to scramble with friends. I havent reinstalled it and no issues so far.

@ Thomas, I don't recall all that info. I want to say just icbinb with bhudvens original kernel (only kernel I used before I started using Anton's). I may have swapped a few system apps from various ROMs, but I know I wasn't having any issues unless you count a reboot about once every 5 days.
Sent from my SGH-T959V using xda premium

I had this happen once. Was running MIUI from Erik, release 0.2, and AntonX 1b3 kernel. I think it may actually have to do with an app as well, I too was running Scramble with Friends when my phone randomly rebooted and everything started force closing and looked like a fresh install of MIUI going crazy.

Just in case it may be related:

Yes it just happened to me 2 days ago. App froze, pulled out battery, rebooted, and just like that all my apps were gone and a bunch of FCs. But its all good now.

I was running vb fb edition when it happened to me about 2 months ago. I didn't have any tweaks on it, just apps that I use daily. A few of you guys claimed to he on VB when it happpened. Could be a rom issue.

Happened to me twice on vb-fb and twice on MIUI. I switched back to a backup i had of vb final fixed and haven had a problem. I was using Antonx's kernel when it happened but I'm using it for vb final now and haven't had issues. I did notice at least 2 of those times it happened an app was updating. I want to say it was Facebook updating one of those times.

Theoretically things like that may happen if you use tweaks that completely remove journaling from the file system and fsync from sqlite. Files and databases can be damaged too easily if for any reason the system reboots without proper shutdown. Not sure if VB has those tweaks though.

I was using Valhalla Final with the latest SMS kernel.

Battery pulls while the phone is froze and letting your battery die while using will both cause this to happen...
Pulling the battery is like taking a thumb drove off usb while its R/W. you're cutting the power to the NAND flash and causing a discharge... No bueno! You wouldn't yank your PC 's power out of the wall because Windows froze; would you?
No, just like a PC, if you hold down the power button on your phone it will shutdown, and our phone will actually reboot when the power button is held down for 5 - 10 seconds.
The only time I've had this problem is after doing battery pull or having the battery die while in use. The funny thing is that it won't do after first booting the phone but on the next boot :-/ I'm still about 90 percent sure that interrupting power while a R/W is being done is the problem in most cases, especially since most reported that it happened after a battery pull...

Phone rebooted a couple of nights ago just before plugging in my headphones. It was still in a sleep state. Just woke up and rebooted. Afterwards I had force closes on everything including my launchers.
Forced a reboot into recovery, fixed permissions, and the phone booted properly. Just about all my apps were gone though. Very strange.
Running that crazy sweet scom4.4 with Antons 1.1.0 kernel. KD1 modem.
Of course I modified it to my looking, but that's the base software.
Edit: titanium restored everything back to it's proper state. Good thing I had a fresh backup. Others might not be so lucky.

So after using the One Click Back to Stock + root for 2 months, I did not experience the phone losing the data. Even if the phone locked up and I had to pull the battery, everything was still there after the reboot. I did not get any FC or missing apps.
I'd hate to say it is something with the custom ROMs. I even get better battery life with the stock ROM.

Happened to me yesterday uaing fb's valhalla black. Basically rebooted and factory reseted itself.

[Q] AT&T Samsung Infuse 4g randomly shutting off (SOLVED)

My samsung infuse randomly shuts off when I plug my phone in to the charger. But it's not consistent. It only happens every once in awhile. It shuts off and then the charging screen won't even show the battery. It will show something like a circle indicating that it's loading and that screen will just keep blinking on and off, as soon as I unplug it the phone powers on. I am using a third-party battery but I also still have the original. I don't know if it does it with the original battery as well. But I will start paying to keep track now.

Try the stock battery.
But also try another charging / USB cable. Maybe a short in the cable you have. Let us know your results
Sent from my SGH-I997 using xda app-developers app

Your not alone in this, i'm having same issue with an infuse i'm trying to sell. i found out that if i press the powerbutton like repeatedly around 5 to 10 times while the circle indicator is showing, the phone will display the green battery charging. I'm on stock firmware too and i believe this may be due to the power button or faulty powerbutton.

since switching back to the original battery that came with the phone I have not experienced any "random power off's" Thanks for the tip.

I am having a similar issue. After bricking my phone, I returned it to stock, used Heimdahl to get the Gingerbread deodexed and rooted version UCLB3 and added the Adrenaline Injector Tweak and the phone is working Terrific. Faster than I would have imagined. I do not have a rom flashed as I am happy with the debloated stock version. However, for whatever reason it shuts down randomly while I am not using it and I then have to plug it into a charger and wait for the on screen battery appears and disappears to turn the phone back on. This occurred when I returned it to stock and continues now. Has anyone else experienced this? Any suggestions or solutions? Any help is greatly appreciated.

Re: [Q] AT&T Samsung Infuse 4g randomly shutting off
The only thing I can think of, is it has something to do with the adrenaline tweak you say you added to it. My reasoning us because I am also using deodexed stock/rooted ROM just without the tweak and do not encounter this problem. you used option c from the XDa website am I right? If do it's the same one I'm on now. I'd start from scratch and re download everything fresh and reroot the phone try it for a couple days without the tweak and see if that solves the issue then add the tweak and if it starts up again you know whats causing it. That's just what I'd do. I hope this helps

I think Oreo is right. Adrenaline tweak will do that.
Use a root tool like root explorer or adb and delete the /etc/init.d folder or the content.
If you have cwm recovery, flash zen tool kit, remove tweak and apply light tweak.

Re: [Q] AT&T Samsung Infuse 4g randomly shutting off
Thanks for the feed back. Had to try it out for the whole day. I swapped batteries with my son who also had an Infuse and I am happy to say that I have not had the issue in 24hours and nor has he. Thanks for chiming in because these will be steps that I will try if it occurs again.
