Same thing happened to me at first.. Serendipity 7 didn't do random shutdowns for about 2 or 3 days.. then BOOM it started happening again. From what I understand there is nothing kernel\rom\software related that we can do to permanently fix the problem.. The only solution is to get it replaced.

Trust me, I've been flashing every combination of kernels and roms (Froyo and Gingerbread), and it might seem fixed at first, but then it eventually happens again.

I'd recommend you try and get it replaced under warranty before it expires.

I got my cap back in December and had the random shutdowns regularly. I talked with Rogers and Bestbuy from whom I got the phone and they said update coming (2.2) and that will fix the problem they had never heard of -.- . So i waited patiently...too patiently and when the update came and didnt fix the problem I was past the store warranty and wasnt willing to give up my phone to send it in for "repairs" to samsung and I have kept using CKA since I got the phone. Ocassionally i've forgotten to run it after boot ups and get the subtle reminder when the phone has shut down.... until last week... I decided after sitting on the sidelines that I wanted to play a little more and rooted my phone, installed cwm, TB, root explorer to explore. Then I saw the online theme kitchen and thought "wow I can finally change that crappy battery icon." So i changed it and ever since I havent restarted CKA and froze it after I realised I had not been running it and have not had a single shutdown and have gained at least 2% battery use per hour without it running.

Too many words for a simple story, I know. But I was in a sharing mood.

P.S. I did this to the wifes phone last weekend aswell and she has not had a random shutdown either. Coincidence or something that works I dunno.
[Captivate Q&A, Help & Troubleshooting] id10terror:
Well I found a problem with the refurb I got.. The GPS was pretty bad and one of the capacitive buttons on the bottom wouldn't light up..

Anyways, went back today and they gave me another phone (on my 3rd now).. Good news is that GPS is accurate as hell without any fixes.. Tracking and locks are spot on with Google maps.. and everything seems to work perfectly as well with no random shutdowns.. It looks like I have a winner here! :D

This one is also batch 10.11

Random Shutdown FIX!!!!

[Captivate Q&A, Help & Troubleshooting] bubu123:
This is far from being a fix.

I'm also using MIUI rom and haven't got a random shutdown since. But it is not because this rom fixes the problem, it's because the battery use of the rom is high. Therefore the voltage that the device takes from the battery is also high. Actually it's the same as using the app that prevents the phone from getting into sleep.

As soon as CM7 will fix the battery issue (IMO it's not going to happen), then our phones will suffer from the random shutdown disease again.
[Captivate Q&A, Help & Troubleshooting] Donut Driver:
Try what I posted on the previous page... I don't know why or how it worked or even if it should have worked... but something in the files stopped it from happening after I used the UOT kitchen to change my battery icon. Not only did it fix my random shutdowns it also fixed my wifes phone. We are both still on stock and after rooting it is the only mod either of us have. Its been 1 month today since I did that and not a single shutdown. I have had 235 and currently 356 hours wihtout a shutdown other than manual reboots.

Would be nice to know why it works and why it shouldnt work but those answers are well above my pay grade.
[Captivate Q&A, Help & Troubleshooting] mrsubway:
Weird. I have a 1012 that's doing it. Aren't the new phones NOT supposed to do this? Funny thing is, it really didn't start until I flashed the official Froyo. On 2.1, it didn't do it. I think there is more of a software issue here than people think. I'm using keep alive, no choice.
[Captivate Q&A, Help & Troubleshooting] RCDuke:
I've only had this issue since I've flashed a modified stock ROM such as Apex or Cognition; the problem never appeared on complete stock or Cyanogenmod 7.

Anyone have any ideas as to why this occurs?
[Captivate Q&A, Help & Troubleshooting] Miami_Son:
It's too random to really know exactly. My first 2 Cappys both suffered from it. My 3rd has been running Andromeda (1.2 then 3) since February and not a single random shutdown in all that time.

I just started having this issue on my model 1011 with imei in the 9000's. It was happening on CM7 so I re-flashed to serendipity 7 and it's still happening. Unfortunately I did not get it through ATT. I bought it new off ebay so no chance of warranty(I think)... Looks like I might be buying a new phone soon

EDIT: When I bought it I made SURE my IMEI was above the number in the press release so I wouldn't have this problem.
[Captivate Q&A, Help & Troubleshooting] momogee:
Does anyone have any documentation about this? I have gone through Rogers' warranty junk 3 times for the same problems and they for sure haven't cited this. I sent complaint emails to them about getting broken refurbs and they said they were happy to fulfill the warranty by constantly sending my broken refurbs.

I assume no one has come up with a true solution (beyond the captivate keep alive app). I am surprised the roms arent including process checkers that keep the phone from going into a deep sleep that causes the reboots

Random Shutdown Trouble shooting Steps

Hi all,

I have read many many pages of complaints and guesses. I too suffer from the occasional, maybe twice a week, random shutdown.

What I have yet to see is a process by which to trouble shoot this beyond just guessing.

Now, I do not know enough about android or linux to do what I normally would do in windows.

So how do I:

Turn on logging

find crash dumps

enable crash dumps

analyze crash dumps and logs

see the stack dump at the time of the shutdown

enble an event to copy out dumps and logs in the event of a restart after a bad powerdown.

In short How do we troubleshoot this from a structured systems point of view.

If this is answered elsewhere or seems noobish then kill my karma, otherwise let's kick this bug in the behind.

Digitronically yours,

Salty Foam

I was having the same problem. Though I haven't noticed a shut down since I flashed Serendipity 6.4 five days ago. Not sure if this really solved the problem. I also have ran the Captivate Keep Alive app from time to time (this did work).

Can anyone confirm that flashing this rom fixed the problem? Or do I need to do something else?

Thanks in advance.

P.s. I am rather new to android, but a very quick learner.

What about those who have MIUI? Is solved in this ROM?
[Captivate Q&A, Help & Troubleshooting] hauj0bb:
I used to get random shutdowns once or twice a day on stock, and custom roms/kernels until I flashed CM7. Not had one random shutdown since.

I have CM7 and the shutdowns are daily....:(

What baseband have you got?
[Captivate Q&A, Help & Troubleshooting] infuse4g:
Get the phone warrantied. That was my fix. some captivate were shipped with that issue and a new phone is your best bet

[Captivate Q&A, Help & Troubleshooting] Jeffu:
I get the impression after having read up on this quite frequently before, that there are some phones that suffer from random shutdowns due to software issues. The majority seem to be inherently defective (so, hardware?), and the time in which it takes to happen varies phone to phone. Cause is still yet to be determined despite so many smart XDA members, can't imagine someone actually figuring it out now as the phone gets older.

I would think to just look for a new phone at this point. Fortunately mine seemed to stop after removing my Task Killer app. :P
[Captivate Q&A, Help & Troubleshooting] vaickiballs:
Mine just suffer this on CM7 and without any app...I'm going to install MIUI and try.

On stock Froyo 2.2, very strangely the signal got lost and I had to extract the battery and put it again. Rebooting wasn't enough
[Captivate Q&A, Help & Troubleshooting] infuse4g:
Sorry about that. There's an app that's probably been mentioned in the previous 107 pages called captivate awake. You could give that a shot. If you already have sorry about being redundant. Anyone try congition rom?
[Captivate Q&A, Help & Troubleshooting] evolver10:
The only time I've ever had shut downs is when I installed Cognition. I'd have to do a battery pull to reboot. I uninstalled Cognition and haven't had a problem since. Running stock 2.2 rooted w/voodoo lagfix. My phone is within the defect date as well. I'm reluctant to flash another ROM because I don't want the shut downs. That's a shame because I'd really love to try Andromeda 3.
[Captivate Q&A, Help & Troubleshooting] WarEduar:
Same problem here, just flashed a new kernel from cm7.
[Captivate Q&A, Help & Troubleshooting] vaickiballs:

Not sure if I have the same issue here, but every now and then, mine will seemingly shut down, and I won't even be able to turn it back on. I have to remove the battery first in order to get it to turn back on. It doesn't happen too often, but it's still very annoying, especially if I don't notice it right away.

This happened to me with all the stock GB Roms. I switched to KK4 roms with custom kernels and for two weeks this has not happened. As someone indicated before, try switching the kernel first, if not maybe a new Rom. Hope you can find a solution
[Captivate Q&A, Help & Troubleshooting] AriaOfSorrow:
Thanks for the responses. How can I switch to a different kernel though? I don't see any options to do so on the CyanogenMod site, ROM manager, or anything. If any of you have a site that could explain the process more, I'd appreciate it. Hopefully it'll end up fixing the problem for me and the other people that are having the problem.
[Captivate Q&A, Help & Troubleshooting] jmtheiss:
Go look in the development section for either the Glitch or Platypus kernels. Download one of them to your internal SD card, reboot into recovery, and flash the zip from "install zip from sd card". Then reboot.
[Captivate Q&A, Help & Troubleshooting] AriaOfSorrow:
OK, I picked up Glitch. For some reason it wouldn't install straight away from recovery, but I was able to successfully install it with ROM manager. I'll post again here if it doesn't solve my problem(s), otherwise it'll have fixed everything.
[Captivate Q&A, Help & Troubleshooting] Silencer96:
Make sure you tick off set on boot in SetCPU.

Your captivate shouldn't be overclocked to anything over 1.4Ghz.

Hope that helps :)
[Captivate Q&A, Help & Troubleshooting] KreepyKen:
I think it's more of a device issue. Mine does this (build 1101), and I'm on stock Froyo (rooted). It happens 2 or 3 times a week. My current cappy is a replacement. My first one (build 1108) did it, too (less often), both on stock Eclair and on Paragon ROM. It seems that swapping kernal/rom might work for a while, but then the problem usually comes back. I've only heard of a couple people who got lucky enough to fix the problem permanently.

I think it's most likely that if your device does it, it does it; and if it doesn't, then it doesn't...regardless of kernal/rom.

I have, however, noticed that about 75% of the time my current phone does this is when I'm installing (or updating) APKs from the Amazon AppStore. There could be a definite trigger for this event that is prevalent in the Amazon AppStore. No idea what it could be, though.

And for the record, I don't think that the phone actually shuts down. It looks like it does, but it's happened to me in a dark room a couple times, and the screen is still on. It's black and looks like it's turned off when the room lights are on, but with all the room lights off, you can tell the screen is still illuminated, but displaying all black. Something is going haywire on the phone (which would explain why after just a few minutes, the battery is drained).
[Captivate Q&A, Help & Troubleshooting] AriaOfSorrow:
I agree with you, I don't think the phone is actually off. I didn't really know how else to describe it though. The phone may as well be off anyway, since there doesn't seem to be any way to get the screen back, other than removing the battery and turning the phone back on. Also, for me, the battery doesn't get drained. The last time it happened, my phone was at 52 last I had noticed it. Then once I realized it happened and removed the battery, it was at 49 when I got back on. And I don't have the Amazon Appstore, nor have I ever either. It's a shame that there doesn't seem to be any actual fix for it. At this point I'd be happy if I could just get my messages to never force close.

Does ice cream sandwich fix the problem?
[Captivate Q&A, Help & Troubleshooting] liquid64:
My experience is that the phone really does shut down completely. It just happened again on my phone. I immediately tried texting, and then calling it. Neither one woke it up. I am currently using one of the KK4 leaked builds (Serenity 6.3), with the corn kernel. The frequency of this shutdown happening is the same when I was running the official froyo build. I have had my phone since July 2010, so I don't really have a warranty. I have been using the "captivate keep alive pro" app, to help work around the issue, but I would love to see some type of solution "baked" into the kernel.
[Captivate Q&A, Help & Troubleshooting] M973:
I also started to get random shut downs past few months, I was on a custom Froyo rom I had been on for a very long time, just went to a custom KK4 rom (Illuminance 3.0.1), didn't think it would help, and didn't, it shut down overnight :( Also a 1007 build. May try the Captivate keep alive app, but don't want to sacrifice too much battery. Would try to press them for a replacement, but I've heard a few say even their replacement still shut down, and some had some scratches, etc. (I've kept mine in perfect condition, not a scuff) :)

Wish there was a good solution, frustrating to not be able to rely on my phone (for alarm, calls, etc.)
[Captivate Q&A, Help & Troubleshooting] liquid64:
As an update to my previous post, I have since wiped the phone again, and have loaded the cm7 kanged (Jan 17, 2011 build), along with the Glitch kernel (13.1), and the kg3 modem. So far, I have not had the shutdown on the phone as of yet. I will definitely keep this thread updated, but going ASOP may have done the trick. I have noticed that CM7 does not allow the battery to get to 100% charge. As one user mentioned previously, I really think the issue revolves around overcharging. My normal behavior is that I plug my phone in at the end of the night, and then unplug it when I get up in the morning. The shutdown usually happens 30 min to an hour after unplugging. This morning, it did not shut down. Again, I will post if something changes, but I just wanted to share my experience with this issue.
[Captivate Q&A, Help & Troubleshooting] vaickiballs:
I'm with you, I'm from Spain and my random shutdowns comes always with lost service and as you said, after 30m - hour until unplugged, so this make me thing that is relate with the full charge.

First I though that this was because of the baseband, but after trying almost all versions without success, my conclusion is the same like you.

I'll try to no get full charge and let's see....

I too have been recently hit with he shutdown bug. I bought my phone in Nov. of 2010 (1010 build) and had this issue since day one.

So my wife's phone is above the imei number for the known att phones that do it, build # is 1009, and its had no issues with random shut offs.... Until I updated it to gingerbread today. What gives here? Is kk4 broken?
[Captivate Q&A, Help & Troubleshooting] M973:
Mine is a 1007 build, was on Eclair, then Froyo, now GB. It didn't start shutting down until a few months ago (after being on Froyo for many months), so maybe, as some have suggested, it's something that takes time (unfortunately just after your warranty has expired).

I was hoping it was related to the Froyo rom I was on, but still does it now on GB.

Seems mostly when it's more than 75% charged, and idle, usually overnight. Currently trying the Captivate keep alive app to see if it helps.
[Captivate Q&A, Help & Troubleshooting] T Tyme:

Finaly fixed

Hi all,

i have had the same issue with random shutdowns.

When I was on stock rom (package GT_I9000_XWJVB_XXJVK_NEEJV3_Sbl) i had shutdowns 5 - 10 times in a day. Not depending on battery charge. Just only small app. Captivate Keep Alive from market works, but drain a battery a lot (no sleep mode).

So I decline to install CM7. Somewhere I found, that CM7 by KANG maybe work.

Finaly now i am on Android 2.3.7, base band T959TLJL3, kernel 2.6.35.14-g3088622 pawitp@pawitpmbp #1, Modification CyanogenMod-7.2.0-RC0-Captivate-KANG, build nr. GWK74

Update filename: update-cm-7.2.0-RC0-Captivate-KANG-signed.01192012-0153.zip

And finaly i have no shutdowns in past two weeks, phone work well, no problem with wifi, bluetooth, data, gps, etc. :cool:

Hope it will work also for other members. I wish you luck.
