[Captivate Q&A, Help & Troubleshooting] Soccer_Dad:
Another day of testing done. Here is what I have (disclosure - testing would be more reliable if I could take days or months, rather than hours, but my Sleep Deaths have been very "reliable" - within an hour every time):

I tested the prior configuration (KJ3) with Background on and Auto Sync off, and still got SOD's. And I can't get GTalk without Background, so it's a non-starter.

Next test was to fall back to Froyo. I loaded Serendipity - Android 2.2.1. It had worked for me before. I ran the base ROM for a couple hours without SOD's, even with Background and Auto Sync. Now we're getting somewhere. But the ROM had no exchange email associated with it, so I went to the Serendipity website and added GTalk, Exchange email, and circle battery mod. Then put the phone in sleep mode and waited for an hour. It didn't wake up.

Next test was to go back and delete all the accounts other than Google, to see if just the presence of the program (or circle mod) caused the SOD's. An hour later, the phone was still active. Oh ho. Could it be the Email program? I downloaded hotmail from the Market. I signed into it. I put the phone to sleep. An hour later, it came back on! I cut short the next hour (to 30 minutes) to test again while writing, and I still have a powered phone. With Gmail, Gtalk, and Hotmail.

So, if the phone doesn't die overnight, I'm going to flash up to either GB (Cognition or Continuum, assuming I can find the files) or to ICS and see if the above behavior continues to be predictable on a more current ROM (IIRC, the GPS made a big improvement from Froyo to GB among other things).

Edit: No sleep deaths with Froyo/Serendipity and Background data data on overnight, as long as I use "hotmail" rather than "email". So I may be close to figuring out how to get a functional phone again.

Hi. My captivate shuts down 2-5 times of day and i've tested about 10roms ( Froyo, Gingerbread, Honeycomb, these roms and kernels my cappy shutting down) and kernels to find a solution and now i finally find fix the problem. Any ICS rom and Nushor desktop 3189 kernel combo and shuts down have stopped! (many weeks tested and zero shutting downs)

Every time when i install other kernel than Nushor the phone shuts down meny times of day but when i come back for nushor kernel the proplem has solved, why?

Nushor desktop kernel working 100% fine but the camera video recording wont work, HD pictures working fine, that is the only problem for nushor kernel

If somebody fix or update the HD recording working fine, there is 100% working kernel without captivate shutting down.

Kernel:

3.0.8-Fugumod nushor@nushor-desktop #3189 Sun Jan 8 21:13:31 CST 2012

Sorry my bad english, im from Finland =)
[Captivate Q&A, Help & Troubleshooting] rophiroth:
Maybe your cappy has a problem with camera video recording hehe. What type of shutdowns do you have?
[Captivate Q&A, Help & Troubleshooting] eddie85u:
Has anyone else tried this kernel?

Is it the one from this link?

Please confirm so I can try it :)
[Captivate Q&A, Help & Troubleshooting] eddie85u:
well the kernel I posted didn't work for me, I tried all the governors with no luck :(
[Captivate Q&A, Help & Troubleshooting] whusted:
No joy here. I'd had problems with my phone shutting down around once twenty-four hours. Got a replacement that would shut down around every twenty minutes. Returned it for the first one (at the store's insistence that it could be a bad card.) Tried this fix and the phone stayed up for 28 hours before it shut down. Going to return it for yet another phone. Maybe third time's a charm?

[Captivate Q&A, Help & Troubleshooting] RexEscape:
If you can, will you take note of the device's manufactured date? Some of us are thinking it could be a bad batch. You will see that date when you register the device on Samsung's website (immediately after entering the Serial / IMEI #) My first device was manufactured sometime in July. I returned it. My second device (now) was manufactured on August 2, 2010. Let's see if this one continues to stay on.
[Captivate Q&A, Help & Troubleshooting] tsquare2112:
Purchased mine yesterday. I started having this problem this morning. Date on registration is 7/31/2010. I DO NOT want to return this phone! Over the past 2 months I have purchased allot of phones from the same store, they know me, but I still do not want to have to return it. I just got it set up how I wanted it.

I applied the Load Monitor, will update.

Took off charger after all night, checked email, took shower, phone was off.

Turned it back on, on for about 5 mins.

Turned it back on, on for about 10 mins.

Turned it back on, on for about 20 mins.

It has shut down twice again, but I don't know how long it was on or off.
[Captivate Q&A, Help & Troubleshooting] tsquare2112:
Well, it lasted about an hour without shutting down. Guess I will stop by the store on my way home and exchange it. I hope the next one works.
[Captivate Q&A, Help & Troubleshooting] slic33:
Do you also have the Power Saving Mode under Settings=>Sound and Display turned off? Two other suggestions are to keep the phone in Debug mode, and to do a battery pull after an unwanted shutdown.

If that doesn't work, try verbally abusing the phone for a solid 5-10 minutes. Seemed to do the trick for me, haven't had an unwanted shutdown in 2 weeks! :D
[Captivate Q&A, Help & Troubleshooting] rupertrupert:
I don't think it's a batch issue -- my brother and I got Captivates on the same day from the same store, and he's had no problems while mine has been shutting off about every other day.

Neither load monitor nor the power saving mode deactivation has helped; store yesterday thinks it's a bad SIM card, but I'm highly doubtful. Bah.
[Captivate Q&A, Help & Troubleshooting] Jack45:
I can understand the power saving mode attempt (although that's already been debunked by the previous poster), but why would debug mode be worth consideration?
[Captivate Q&A, Help & Troubleshooting] slic33:
My thinking was since debug is usually more cpu intensive, it would help keep the phone awake. Just something I tried, really just a shot in the dark at this point.

Anyone tried rooting your phone and setting the min cpu? Based on my experience with this phone, I'm also of the opinion it's a power management issue. I'm on my 2nd captivate, the first was shutting off every 5 mins. My new one shutoff twice the first day I had it, something must of changed though cause it stays on now. I'm trying to figure out what that change was..
[Captivate Q&A, Help & Troubleshooting] Shuggins:
The load monitor"fix" seems to have worked but it has only been 24 hours since I installed it. I have had zero shutdowns since installation.
[Captivate Q&A, Help & Troubleshooting] tbrouwer:
I have not had any shutdowns since the fix, but now my battery life is horrid when the phone is sitting there not being used. Anybody else experiencing this?
[Captivate Q&A, Help & Troubleshooting] Mrjinwa:
have had my phone for a little over two weeks, first shutdown was a few days after I got it, then didn't happen for a few days and then again, I applied the Monitor fix and so far the phone hasn't shut down in 3 days. I'll see if the fix continues to work, or take the phone back if it shuts down again.
[Captivate Q&A, Help & Troubleshooting] tbrouwer:
How has your battery life been since applying the fix?
[Captivate Q&A, Help & Troubleshooting] tbrouwer:
You think its OS related? Many people do not have this issue at all, which is why im pondering returning for a new device.
[Captivate Q&A, Help & Troubleshooting] tbrouwer:
Curious, has anybody tried the updated samsung firmware that samsung put on their website a week or two ago?
[Captivate Q&A, Help & Troubleshooting] slic33:
Can you post a link to that firmware? I wasn't able to find it on their website. The only download I could find was the windows driver.

However, I'm a bit weary as there are only a small percentage of users having our problem. But also, seems most of the people in this thread that had their phone swapped continue to have the problem!
[Captivate Q&A, Help & Troubleshooting] whusted:
Sorry, returned the phone August 18th. As of today -knocking on wood- no random shutdowns! And it's now been up for almost 46 hours since my last restart.
[Captivate Q&A, Help & Troubleshooting] jeepin95:
I had a similar problem with my first phone and it also never got gps lock ever even trying on 2 different 45 min drives to work. Took that back within a week especially because of the random shutdowns.I've had the new phone almost 2 weeks now and no shutdowns, gps sucks but at least it locks once in awhile.
[Captivate Q&A, Help & Troubleshooting] RexEscape:
My new device doesn't shut down randomly. Good. However it can't consistently lock GPS even though it finds multiple satellites. Bad. Sometimes it doesn't even find any.

I will return this device again and go back to my HTC Fuze (or maybe get the iPhone 4) eek!
[Captivate Q&A, Help & Troubleshooting] fohdeesha:
I want to propose a theory that could very well be incorrect and that I'm sure will be flamed to death but.....I think it may be related to the bootloaders.

My phone obviously came with 2.2, with the original 2.2 bootloaders. I had the random shutdown issue, it would just turn off completely, sometimes even while I was typing. I flashed rom after rom, no fix.

I finally used the i897 ucckk4 odin one click CONTAINS bootloaders odin package. This is obviously a master wipe and reset to 2.3.5 for your phone, but it will flash the absolute latest bootloaders. There is an odin package with JUST 2,3 bootloaders, however they are not the latest 2.3.5 bootloaders. There is a lot of talk of how horribly dangerous it is to flash bootloaders, but the package mentioned above obviously contains both primary and secondary bootloaders, no matter what is on your phone right now, as long as you use a reliable USB cable on a reliable computer when flashing the above package, you will be perfectly fine.

Using that one click will give you the latest BL's with a stock 2.3.5 rom. I then use Odin to flash a corn 2.3.5 kernel which gives you CWM. Then I use CWM to flash whatever rom I want, and now my phone is absolutely up to date.

After I flashed that package with the latest bootloaders, the shutdowns are absolutely gone - as in through the three rom's I've been messing with since flashing the 2.3.5 BL's, I haven't had a single shutdown. Before flashing BL's I tried every rom and kernel for the captivate I could find, but staying on 2.2 BL's, and the shutdown continued. Tried master wipes and one clicks, no difference. Try the one click mentioned above! Obviously you will have to reinstall your rom. if you're thinking you can find the one click with JUST the bootloaders so you don't have to reinstall your rom - don't bother, in every instance for me, upgrading bootloaders will confuse your rom and it will bootloop.

In my case, upgrading bootloaders made my shutdown issue disappear, but of course it could be an isolated case. My girlfriend also has a captivate, and she has the batch of captivates that will not let you access download mode. She has the random shutdowns so bad that it's driving her mad and she's ready to get an iPhone with her upgrade. I have read that the batch of phones with an inaccessible download mode is actually a slightly corrupt secondary bootloader. This leads me to believe even further that there is a link between bootloaders and stability/shutdown issues.

I have a USB jig on the way to get her phone into download mode, then I will flash the latest bootloaders, then probably a jellybean rom. I will report back if this fixes her shutdowns as well

Sorry for the lengthy post! Just wanted to share my findings
[Captivate Q&A, Help & Troubleshooting] lavero.burgos:
Yeah flashing a GB BOOTLOADER made the trick for me too but for some people seems not to work. It is why is called a theory.

~ V
[Captivate Q&A, Help & Troubleshooting] fohdeesha:
I'm curious if the people in which it did not work flashed the 2.3 bootloaders...not the newest 2.3.5

I flashed the 2.3 bootloaders and the problem persisted...It was not until I flashed the i897 ucckk4 2.3.5 BL's that the problem completely disappeared

If anyone of you are willing to flash the i897 ucckk4 CONTAINS bootloaders one click, please do so and report back!
[Captivate Q&A, Help & Troubleshooting] lavero.burgos:
I posted my experience about this here: http://xdaforums.com/showpost.php?p=25722784&postcount=1153 but that is a I900 bootloader.

I forgot i had installed a I9000 bootloader sorry not the i897 GB bootloader but it worked for me until now is working good :). So even better people have more choices.

~ V
[Captivate Q&A, Help & Troubleshooting] fohdeesha:
Ah interesting, I would think i9000 bootloaders on an i897 would CAUSE issues!

I put together a little package for anyone with an i897 captivate still having shutdown issues and is still frustrated. Give this a try, I have a feeling they will disappear.

Use this Odin one click to wipe/reset your phone to the latest official rom, uckk4. This one click INCLUDES the latest bootloaders ever released for our phone, both primary and secondary. These are the bootloaders that have made mine and others shutdown issue disappear. This is completely safe to one-click no matter what is on your phone right now, just use a reliable USB cable like with any other flash. No matter what state your phone is in, if you can get into download mode, this will wipe your phone to 2.3.5 with 2.3.5 bootloaders

http://fohdeesha.com/data/other/android/i897uckk4 with latest BL.zip

After you've done that, use this odin package to install CWM recovery for the stock 2.3.5 installation you now have

http://fohdeesha.com/data/other/android/uckk4 CWM recovery.zip

Now you can get into CWM and flash whatever rom you want! ICS, jellybean, whatever. And you now have the latest 2.3.5 bootloaders and your shutdown issue should be gone. I've done this several times to several captivates now with zero issues. I hope this helps someone!
[Captivate Q&A, Help & Troubleshooting] eddie85u:
I'll give your solution a try. Right now I'm using INFINITUM-LBR-V1.0.1-CAPPY, a rom I like very much, my shutdowns start appearing below 90% charge, and mostly when the phone is cold. Sometimes, with very low use, it can stay in my pocket the whole day and will reach 30% charge without shutting down, but if I leave it on a table or something, it will surely shut down, I must say that I live in a cold-ish city (Bogotá, Colombia) but it's not too cold, I mean, it has never snowed here.

Anyway, I'm gonna try this, so what I believe I should do, is the following:

Backup with TiBu

Download and use Odin (the one from fohdeesha)

Once I'm on GB 2.3.5 do I loose the root?

Anyway, I then flash the CMW

And from then I flash the rom twice (I read somewhere that is was better to flash the rom twice)

And restore TiBu backup.

That should be it, right?
[Captivate Q&A, Help & Troubleshooting] fohdeesha:
basically yes...I don't know how reliable your tibu restore will be since it will be restoring to a phone with different bootloaders which can sometimes alter how a kernel configures itself and installs I believe. If you're looking for a newer rom, I HIGHLY recommend helly bean. It is super fast, and super stable. The most actively developed and supported helly bean (perhaps all around) rom for our beloved captivate. I don't have any experience with that rom, there's a slight chance it could be causing your shutdowns. Do you know what kernel it uses?

http://xdaforums.com/showthread.php?t=1783064
[Captivate Q&A, Help & Troubleshooting] eddie85u:
That rom uses glitch kernel, anyway, the bootloaders didn't fix my shutdowns :s I'm gonna try that JB rom you recomended.
[Captivate Q&A, Help & Troubleshooting] lavero.burgos:
I used to use infinitum LBR after I changed to the I9000 boot loader and never had issues, when I figured devil kernel was better I changed from stock glitch kernel to devil because with glitch kernel my phone was getting slow.

A tip: flash ROMs twice in a row (dirty flash) for sometime and see if that helps a bit.

I guess it will depend on other factors like phones serial. Mine is 1007 and changing bootloader fixed my phone.

~ V
[Captivate Q&A, Help & Troubleshooting] eddie85u:
I've also tried devil kernel and every one of it's governors with no luck. I tried your suggestion when you first posted it (i9000 bootloader) and I always flash a rom twice, but nothing has ever worked for me. :crying:

I'm trying this rom, but now I can't get a signal... I have no imei, no nothing, and I followed your steps to the letter. This is getting really annoying. I used to solve the issue with Galaxy S Unlock, but now it doesn't even work by going back to the rom it used to work (going back to stock GB 2.3.5 first of course).
[Captivate Q&A, Help & Troubleshooting] thecrazyman:
Problem solved for me. . .Hopefully

My cousin gave me his AT&T Galaxy Captivate. I love its design knowing that it's Amoled and has 4inch screen! :D

However I experienced similar shutdowns and I'm so annoyed because if this problem continious, then this phone is totally NOT RELIABLE!

I almost threw the phone because of dissappointment but before doing so.. I thought I might need to look first for solutions before dumping this phone.

It's running jellybean custom rom and the battery percentage drops drasticaly. It stops charging when it reahces 94-96% then whenever i use the phone to play music or watch videos online, it shuts down upon reaching 45-60% battery! what the heck?! :eek:

When I turn it on, the battery says that it needs to be charged because it's down to 1-4%???!!! :crying:

I thought this is just a software glitch to I kept on changing roms but still the same. Even on standby mode, the battery drops fast so I have been charging it twice a day. Then, I removed the battery and noticed that it's a bit bloated and thought that this might be causing the problem so I went to the Mall and purhased an expensive samsung battery.

Then I noticed a big difference on its battery percentage. No shutdowns for the past 24hours and hopefully will continue like this :laugh:

But I will still monitor it's behavior. If symptoms persists, I'll call the doctor to hammer it down! haha
[Captivate Q&A, Help & Troubleshooting] johnnyrichter:
Just did this and finished installing the few apps I use. Hopefully I'll be reporting back with good news.

FWIW, my SoDs were completely random. Sometimes I can install a new kernel and rom and get 2-4 days without one, then get a bunch in a day, then after that get 1-2 a day and almost always overnight while I'm asleep. I really hope this method fixes it for me because these sleep deaths are incredibly annoying.
[Captivate Q&A, Help & Troubleshooting] johnnyrichter:
No dice. Seems like every time it idles it suffers a sleep death. At this point I may just see about getting an S2 or newer S1 cappy that had the issue fixed by Samsung.
[Captivate Q&A, Help & Troubleshooting] dang3r1917:
I just got my friend's captivate for free, but it's having random shut down issues. It's not SOD, because my own captivate use to experience that so I know how that goes. It literally just shuts down on it's own, as in I have to hold the power button to turn it back on. I've flashed LANIGHT v8 and v8.5, same thing. It's usually fine but when it sits in one place for a while, it turns off (like when sitting overnight, or just for a couple hours on a table). I was going to make a new thread for this but the title would have been exactly the same...but it's not an SOD issue. Any insight would be appreciated.
[Captivate Q&A, Help & Troubleshooting] lavero.burgos:
Read my post some pages back about to flash i9000 bootloader that was the only thing that really worked 100% not evne one SOD, good luck. I did try the latest suggestion of a user flashing the most recent bootloader for the cappy but still sometimes the phone shutdown by itself. So it's yet not a 100% cure at list for my phone so i went back to the i9000.

I'm going to try this on my captivate, I had put it in my closet thinking it was useless! Big thank you!
[Captivate Q&A, Help & Troubleshooting] Aranen_Zen:
Mine does this. Except I can reliably reproduce it. It does it anytime you keep the hotspot turned on for 10 minutes....unless you have the old keep captivate alive app running. Its done it forever, from stock but rooted 2.1, thru countless ROMs, now on cyanogen mod 10. It wilt do it if the screen is on though. I will be upgrading soon and basically it's become the way my nexus 7 had internet away from home but still annoying.....
[Captivate Q&A, Help & Troubleshooting] RamblingBarba:
Battery bloated

My Cappy was suffering the random shutdown as well. I had great battery life and no charging problems. However, after doing a battery pull I found the back under some pressure when I put it back on. I pulled that battery out, placed on a hard smooth surface and found it had begun to bloat in the middle. I bought a new and it's been smooth sailing since. Maybe worth a look...
[Captivate Q&A, Help & Troubleshooting] Aranen_Zen:
Had that battery problem. Replaced it. Problem with 10 minute hotspot shut down persists. I finally found the solution. Got a Note 2 yesterday. ..:D:p
[Captivate Q&A, Help & Troubleshooting] dozyaustin:
OK .. I remember being on I9000 and also on GB bootloaders and did not get SoD, but the system was super unstable.

Then I went back to stock Eclair and updated to CM9 and then CM10. I am supe stable, but have SoD in the morning right after I unplug the charger. Then they go away.

The thing is, CM10 has GB and then ICS bootloaders, right? The Bootloader image and kernel image still show AT&T, so I am a little skeptical, but I thought I replaced the bootloaders when upgrading to CM9. Throughts?
[Captivate Q&A, Help & Troubleshooting] BWolf56:
CM10 doesn't flash bootloaders. You'll know which bootloaders you're on with your boot screen (I897 or I9000).

In my sig, there's the link for the I9000 BLs if you wanna try them (at your own risk). Although, a couple other things can be checked first: Do you have Deep Idle on? Do you OC?

Also, you can try to up your min Mhz to 200 (from 100).
[Captivate Q&A, Help & Troubleshooting] dozyaustin:
well, I have had no SoD today. I made 2 changes: 1) made sure tomorrow's alarm was set immediately after waking up and 2) yesterday I enabled Google Now. Google now is probably the culprit. My battery life dropped a good deal, but no SoD.

Thanks for the info on bootloaders. I thought I would have had flashed them, given that I went to ICS 9and then JB) from Eclair .. but I will find time and reflash.

I did not modify the stock CM10 setup - it is too stable for me to mess with it. I am really enjoying the stability. But I have OC'd before, and remember that I could limite SoD by upping the idle Mhz to 200 .. it is good to have a grasp on what is going on - then I can start trying different things and see what gives the best result.

Thanks

Hi, I followed your suggestion of flashing the I9000 bootloader. My phone now gets past the Samsung Galaxy S screen but right after that it goes straight to CMW recovery.

EDIT: No matter what ROM I currently have flashed. (Currently flashing 4.2.1 prenightly CM10.1)
[Captivate Q&A, Help & Troubleshooting] BWolf56:
Having the I9000 bootloaders won't work for everyone and there are quite a few things you can do before flashing them, which I believe were mentioned earlier in this thread.
