Captivate still shutting down

My captivate works fine when running a non rooted stock rom, but as soon as I root it and load my apps it starts to get random shutdowns, so it's not overclocking or undervolting. I'm on darky's right now, and I am getting several shutdowns a day. I tried un installing multiple apps with root access to no avail.. Is it possible for a non root app to cause shut downs? I sent my phone in and it was sent back just fine because it was on stock eclair. I don't want to have to trade it in for an iphone but if it continues to shut down I will. Is there any way to diagnose the problem, or even fix it? I think it is an app issue.

Did you try a different kernel? All phones react different, I can't currently use i9000 roms. Worth a shot.
Caution swyping! Read at your own risk.

I tried Darky's and I got the same thing. I have switched to FireFly and have had no problems at all. Paragon is a good ROM as well.

I had the same problem but I would only have the majority of my shut downs within the first 10% of my battery after a full charge. After that for the most part, it would be just fine after that. I'm using cog 4.1 and have been for the last few months and I can count on 1 hand the number of times it shut off. I found that after a full charge,immediately after taking it off the charger, reboot the phone and it runs all day with no problem since I started doing that.

My best guess is that the officially confirmed bad ram problem is to blame. the rooted apps might be accessing bad sections of the ram and causing crashes. It makes sense that the frequency changes depending on which rom you are using since they all handle ram management differently

See I would think it was my kernel or rom if it didnt happen on stock eclair. It happens at any battery percentage.. I really don't know what to do. I might be able to trade it for an Iphone 3gs.. I really want to keep the phone but it seems like I might be stuck with a permanently shutting down phone.. which I can't keep.

How long have you had it? I just returned mine for a new/refurbed one a few days ago. I bought mine in Oct. I'm lucky enough to have a ATT service store near me. Went in, told them I had the shut down problem. Swapped phones and out the door. They are honoring the 1yr replacement from Samsung. Got a 1009 that has perfect GPS, for now, haha.

I got mine refurb, and sent it in to samsung, no go. Do you think an att store in a mall would honor the one year?

Since yours was refurbed, I think the warranty is limited by everyone to 30 days. Mine was new. One of the few perks to NOT getting a refurb.

I had same problem running seremdipity . Now i run continue and no more shut downs. I guess u should try other Rom like mentioned before

Give AT&T a call via 611 or their 800 number. I think the refurb policy is actually 90 days, but from my experience, if you complain hard enough and be rational and reasonable about your requests, they usually budge. I had the same shut down problem with my captivate. First thing they did was send me a new battery in case that was the problem, didn't have to return my original battery so I now have 2. Then after another call back, they told me to go to the service center and I swapped it out in under 3 minutes no problem. Just make sure to Odin to stock before returning your phone.

install setcpu app and set your min clock to 200 that helped some people with shutdown issues

How many of us are getting reboots

I know theres a poll on issues etc and rebooting is mentioned, but I feel it was too early to poll and people could have voted and had a reboot after...
So question is..... has your phone rebooted? Or just fine?
Also if you could mention how long you had it that would be great....
I just want to know exactly who is having reboots and who hasn't..

Not once on its own.

LOTS of reboots
I have had about 20 in two weeks. I am CURRENTLY getting CONTINUOUS reboots.
It had the LG logo and thinking bar, underneath it said "System checking". Now it has rebooted non-stop (6 times so far as I'm typing).
New phone should arrive on my doorstep within the next hour or so... fingers crossed.

once that I know of. No idea why. It just rebooted while on my desk idle.

In the one week I had the phone (preroot), never. Even after rooting it, never.

Haven't had any issues with mine.

Had 3 reboots in 5 days on my old phone. Nothing yet on new one so far. It has been 3 days. I noticed my old phone was alot hotter than this one. Possibly a hardware issue after all.

Guys, try to turn off gps, I did that and I have 0 reboot and 0 shut down today, I had a lot of reboots and phone turning off by itself before that. I'll see what happens when I charge it tonight and I'll let u guys know.

Theres got to be something thats causing it.
results don't look so good..

Hmmm prerooted I had maybe one and some freezing and lag..
rooted no reboots except running eaglesblood rom and experimental kernel with pauls lag apparentky too much going on there. .

If your phone is rebooting constantly don't even waste your time return it for a new unit. The att galaxy s had the same prob and everyone waited for a fix only to find out it was hardware related....if your in the 14 day window don't even waste your time and end up with a refurb

I bought my g2x a day after launch. For a few days, I didn't experience any reboots. After that they starting happening but not too often. Eventually (by yesterday), it was happening more often. Somewhere in that time frame I did a factory reset to try to improve battery life.
I called tmobile support yesterday and they made do another factory reset and not install any apps. It has been 16 hours without a reboot but that doesn't prove anything, really. First, it doesn't necessarily happen every day. Second, without any non-default apps installed, it may not be taxing the device enough. Third, even if it is an app's fault, it may not be directly the apps fault. Am I supposed to run no apps if that turns out to be the problem?
They will be calling back at three and I'm going to try to push them for a replacement. I'm also having reception issues and the battery could certainly last longer.

None here, gps is not turned off

I am on my 5th G2X... with a build date of 4/3/2011 and I have not had a reboot as of yet with GPS turned on. This has also been the best phone out of all those 5, I have a week left and if I experience problems I will be taking it back. As somoene said dont waste your time your better off returning it then waiting for a fix.

I just took it to the store, told them the problems I was having mentioned the reboots, screen bleed, and data connection issues. Told them I was within the 14days and that Customer Care told me to come to the store and try and get a working phone. I wouldnt talk about the reboots as it may not happen in store if you have screen bleed its easier that way cause you can prove that.
Did you buy it in store, online or over the phone?

S.o.d(screen of death)

So I just got my g2x, rooted,nv and cwm. Flashed cm7 and I keep getting s.o.d(screen of death). I thought was rom problem so I.changed rom and im on xdblasters 1.1.0 and keep on getting them. Any solution orhelp would be appreciated.
Sent from my LG-P999 using XDA App

Not sure I know of a rom for g2x called xdblasters.
Also, what kernal are you using? Are you overclocking or undervolting? Are you using setcpu or pimpmycpu? What is your max and min cpu settings? When you flashed, what was your procedure for wiping? Did you fix permissions after flashing? Did you use a program to restore apps? Did you use that program to restore system settings? Did you choose to restore apps and settings from google account?
The answers to all of these questions could help determine what you've got going on.

I apologize, its x boarders. And well I am using fauxs newest kernel currently using 1.1 overclock but it would also happen while at stock cpu with previous rom.i don't restore with google but I use titanium backup for batch. When I do new roms I always follow the clean slate rule;Wipe data,cache,dalvik,bat stats. occasionally I forget fixing permissions but I do when I get alot of force closes.

I didnt' see you mention formatting /system under mounts and storage. This is a critical step.
If it were me, I would try to keep everything as basic as I could each step of the way so that i could try to pinpoint the issue. Start by wiping everything (including sd card...just backup your user added stuff to your pc) and install a stock rom/kernal. See if it occurs stock...who knows? It's possible your phone is bad. Then if it doesn't misbehave with stock, then I would wipe everything again, including sd cards (interal and external), and flash cm7 (keeping cm7 kernal). I would try manually installing apps again, rather than using titanium backup or google restore. Just hook up to wi-fi (so you don't waste your data mileage) and go to market/myapps and redownload (hopefully you have a list of what you have).
But something to point out. On my phone, when I use CM7 (with stock kernal), I have to increase my minimum cpu frequency to either 312 or 456 instead of the default 216....216 seems to cause my phone to get stuck with the black screen also. The same thing happens when I run an undervolt kernal. So I've learned that my phone simply doesn't like undervolting, overclocking, or lettign the cpu run lower than 400MHz. Maybe that might help you out.

i was about to back up my sd and reformat it for that reason.I already tried formatting eemc mount or internal mem, and nothing. I also stopped using uv kernels and i kept my cpu min at 506 to keep it from doing, but with no result.I just flashed the newest release of xboarders 1.1.1 and i already got 3 sod while the rom is stock with nothing added. I am starting to think phone is bad. I bought the phone on Craigslist, so i might be S.O.L. i Appreciate

what should my mounts look like when i do a system format?

Awesome, hope it stays good.

guess i spoke to soon. Was running fine all day till around 2 i installed setcpu and configured it. Or so i think, so i uninstalled and reset but when i am charging it it keeps turning off. AHHHH headache with this phone. When it runs, its smooth and so fast, i love it, but i dont know whats wrong with it.

I think I'm done with this. Can't figure out a away around this. Awesome phone but overwhelming problems. Appreciate the help everybody.

have you tried a new battery? I believe most of the G2x problems are likely due to a bad batch of batteries.. why you ask I have come to this conclusion? If I OC heavily OR run the LED light when the battery gets low >30%, my phone will shut off. This would conclude the battery cannot supply the needed current for the phone at the lower battery levels... this is my particular battery but I wouldn't doubt there are worse batteries out there AND/OR reported battery levels that are much higher than actual and getting the same problem I have encountered. Food for thought.

I agree with him... I had worst case of s.o.d with my g2x. Atleast 3 times a day I had to take battery out... but I solved it by doing the following
1. Increase min cpu speed 300 or more.
2. Discharging the phone completely and then recharging it completely.
I barely get s.o.d. may be once in 2 weeks. And whenever I do get em. I give my phone a discharge recharge cycle... then its good for next two weeks

What "Screen of Death" are you guys referring to? Never experienced such a thing...
Phone wont wake? Or what? A quick google search for "android screen of death" and "g2x screen of death" revealed pretty much nothing.
Have you pulled a logcat?

I always fully charge and discharge battery for proper calibration. Doesn't seem to be helping in any matter. I also stopped using any CPU management because I thought that was.

The problem is when phone sleeps and doesn't wake up. I have not pulled one, been thinking its hardware related.

Its hardware defect. No matter what ROM you put on the phone, it will continue. Youve gotta call TMO and get a replacement. Sorry if thats not what you wanted to hear.

I agree with the battery theory. I purchased two generic batteries from ebay and they last 3 times as long and have resolved many of the resetting and SOD issues that I was having. Also, updated ROMS seemed to help, and not letting it fall asleep while you are playing games or something memory intensive.

Well I bought a battery, hoping that helps a bit. So far its a lil better than usual. Using stock voltage kernel. When I get new battery I will test

Still suffering from random freezes while in standby.. Anyone else?

I updated my phone (flashed stock 2.2 rom, flashed stock recovery, then used LG updater tool, then ran recovery after flashing) to 2.3 on the day v21e was released and from the day after flashing I am still having to do battery pulls as the phone locks while in standby. Am I the only one having this issue or are there others as well? hopefully the official release doesn't have this problem.

I've had lockups since day 1... It's gets me so mad. I have a replacement coming in a few days. I've tried everything... Rooting, unrooting, and the 2.3.3 update didn't fix anything! But one thing which was weird, is that 2 days ago, when I was at Oceanport, NJ Warped Tour, my phone was in my bag. It was about 98 degrees outside, and my phone was really hot... It managed to stay on the entire time... WHICH WAS WEIRD! But I hope my replacement doesn't have an problems.
My dad has a G2X with NO PROBLEM AT ALL. Absolutely NO screenbleeding whatsoever! and he's NEVER had a lockup/reboot!
7/29 EDIT: I received my replacement G2X in the mail yesterday, and it appears that all of my issues are gone!

I think I'm going to wait until the upgraded ones come out and try to do a return for the newest ones.

I am having the same problem. I got a new g2x about 2 months ago. it was perfect. lost it. got a replacement and have had the same issue you are having. after update i still have the same issue. i just leave it on the charger. i set it to not sleep while charging and it will not shut down. as soon as it is unplugged it will shut down.

I had to wipe my phone and factory reset to make run as it should after to the update

I did that as well, twice actually, but that didn't fix the issue.

I'm trying an experiment by uninstalling setcpu and juicedefender and just letting the kernel manage my cpu. I expect less overall battery life, but I'm hoping that by eliminating the screen-off profile and constant radio on/off, maybe...just MAYBE it might help with my sleep of death, freezes, and random reboots.

I have sinced changed where screen wont timeout for thirty minutes I did two factory resets since update and still does not work time to return or change the rom.

I had very few random reboot issues before the GB update. Maybe 4 or 5 in the months that I've owned the G2x.
Since the GB update I've had several each day. I've hopped around onto various ROMs to see if one would correct the issue and to date, none have. I'm considering restoring my Froyo nandroid to see if that gets my stability back.

Tmo is sending new replacement. Finally got tired of attempts to fix.

You had a defective unit, software wouldn't fix it. If it was a "kernel" issue. One of the custom kernels on XDA should've fixed it.

My g2x froze all the time while idle. I read a thread once that claimed upping the minimum CPU clockspeed to 312MHz fixed the problem, so I used SetCPU to increase it and it stopped freezing after that. Reboots were another issue though...

[Q] Anyone have success fixing restart issues?

I've had my G2X for about a month, and have been experiencing the common issue where my phone randomly shuts off and the only way to get it to turn back on is to pull the battery.
I've installed the GB update, that didn't fix it. Factory reset didn't help either.
Has anyone successfully fixed this issue on their phone? If so, what'd you do? Is there any chance that rooting my phone would correct the problem?
Sorry if there was a post about this, I couldn't find anything talking about if anyone's been able to fix the problem.
Thanks

yes... the onlyhh way to fix the problem is to root! nvflash clock work mod recovery, then flash eagle blood 2.3.3 rom and it is perfect...

Thanks, this did indeed seems to do the trick. Not a single reboot so far after 2.5 days.

My G2X actually restarted on its own today. It was the first time since the first few days I had the phone over a month-month and a half ago. Wasn't really a big deal, lol. It comes back on.

Have been playing with this phone for 3 days now and haven't had any issues (I did install xboarder's stock rooted version). Minor screen bleed is the only issue.

Finally, someone (dmaniscool) who can say they switched to an xda dev'ed ROM and got rid of the lock ups. I've posted many times asking if anybody ACTUALLY FIXED a problem (specifically the battery pull lock up); I got no responses, and someone finally stated it. Great. Next time my wife's G2x locks up, I'm rooting and putting a ROM on it.
Thank you dmaniscool

so, PLEASE dmaniscool, occasionally update this thread with your lack of lock-ups, or if you get a lock-up. PLEASE!!!

Will do, so far so good! I had no experience with rooting, and was able to figure it out looking at the guides available on the forum. It kind of looks intimidating, but it's not actually very difficult.

By restart does everyone mean just shuts down? Mine never restarts, it will just shut off.

Mine did both actually, shut down and restarts. But mostly just shut downs, which required a battery pull to power back on.

My 2 will do both - but I think the "shut-off" is a lock up, because the longer I leave it locked up, the less battery I'll have after I do a battery pull.
8 days of both phones not locking up by doing one restart per day per phone.

Since I raised the minimum CPU speed to 389 from 216, I have far fewer sleeps of death
You don't wanna know where this was sent from.

I've tried every ROM and kernel combination possible and nothing actually fixes these problems for me.

Wow this post was scary at first, I had a thunderbolt and no matter what. RUU, Different ROMS, Stock, Kernels, Radios. Changing all that didn't matter it still turns off constantly and doesn't turn back on till I do it meaning no text or calls, basically same as having a phone on silent all the time without even having the luck chance of pulling it out while ringing.....

I am on miui x.26 (whatever kernal that comes with it) and have over 40 hours of uptime. I haven't had a crash yet, I just manually restart every couple of days because I'm weird like that.
Sent from my LG-P999

Well 6 days into it and I've had a total of 2 shutdowns. I don't know if it was a coincidence, but both times were after being outside when it was ~90 degrees out.
This is still much improved, I used to get 3-4 per day on average.
I'm using Eaglesblood 2.3.3. I'm thinking of trying MIUI because it's so nice looking.

For me I did a battery replacement the first time directly from T-Mobile and the phone continued restarting on me. I was just about to request a replacement phone from T-Mobile until I recently purchased a different brand of battery containing the same specs as the stock battery and to my surprise no overheating and definitely no restarts. I feel that the restarts and lockups are due to faulty batteries shipped out with the phones. I'm suprised no one has mentioned this.

Wow, I told the CostCo kiosk girl I was having lock up problems and I had my grandkids with me. She took my phone and pulled the battery - at the same time my grandson stated he had to go to the bathroom NOW. She either looked at the battery or something on the phone under the battery. I didn't have time to ask. She didn't really comment and gave me my phone back.
Hmmmmmm........

ok so do they know what exactly is causing the shut downs or reboot on this phone? i just got mine today and it was pre installed with gingerbread and idk if there is root for the gingerbread build yet. i just want root but no custom rom for me. i love the stock rom. it kicked the crap out of my sensation 4g as far as speed goes in everyday use.
