My problem started when apps from the anroid market began to update on their own. I'm not sure what apps they were, but my phone when out. After my phone went out, I took the battery, SIM, and Sd card out of the device and tried to reboot it. Now, when my phone boots, it gives me the ATT screen, goes to black with the bottom row buttons lit up and the phone vibrates once and twice in quick succession and then goes out again. My phone has been acting this way for the past 4 days. On occasion the phone will completely boot for a minute or two, and then will go out and reboot to the black screen. I'm not sure what I can do next. I do NOT have a rooted device and the majority of my music is located on the internal sd. (I'm just now figuring out that the internal and external SD are not the same) I don't want to lose the media on the internal sd and I don't want to lose my bookmarks. I have tried to transfer files from the internal to the external sd, on the rare occassion of when my phone fully booted for a quick minute, but I had no such luck. I have tried backing things up on my computer, but I get an error message that the USB is corrupted and has malfunctioned. I have read about ODIN3, but I have not tried to flash the device, everything is the way it was when I bought the phone. Is there any hope for me? Will a hard reset wipe the data off of my internal sd? I just want my media files and possibly save my bookmarks....PLEASE HELP!!!!!!! What can I do?........Samsung Captivate 2.1
No you shouldnt loose your media, use this method.
Thanks a lot!!!!!

Wondering if anyone can think of anything I can try before returning the phone this afternoon.
What happened:
Yesterday, I rebooted the phone because a prog had hung and wasn't responding to force quitting via Applications. When I tried to turn it on, it didn't respond -- zilch. I plugged it in and tried a few times to turn it on over the next hour with no luck. Finally it started to boot and hung at the ATT screen, but after sitting there for a min, horizontal lines appeared across the screen. Tried again over the next hours with the same result.
Left the battery out overnight. A few minutes ago, I tried it again and it actually got past the ATT screens, but after the Samsung logo sequence was done it hung on the blank screen. The phone is rooted and clockworkmoded, so I tried to boot into recovery to do a nandroid restore. No dice: I get an error about not being able to write/read to the sdcard.
So at the black screen, I can shell into the phone. Can't SU (seg fault). Can't get to the internal SD storage (which is all I really want at this pt. I took a bunch of awesome pics while surfing yesterday and want em).
It looks to me like there is some sort of corruption of the internal storage. Any thoughts would be appreciated.
From the looks of it your nand crapped out...

Yeah thats what I'm thinking.
This does highlight a flaw in the storage setup: having internal storage like the iphone is seriously awesome from the usability standpoint. But android is set up to assume that when you back up, it's to a removable card. So I have a Ti backup, but that doesnt help me if I can't get to it if the phone dies.
Seriously bummed. I've had a really crazy # of dead iphones (like 6 over two models -- its one of the reasons I finally switched) but the upside was that when it was switched out I was rocking all my stuff on the new phone within an hour. With this, I'm now starting from scratch.
FWIW: I got the phone working again by wiping user data and reformatting the internal storage. I'm guessing that there was something corrupted.
Here's the warning I'd offer though: Ti backups etc do you no good if they're on the same file system as the phone boots off of. I was backing up regularly, but since they were on the internal drive that did me no good. Unless I'm missing something, Ti doesn't allow you to choose a location (just a folder name) for backups.
if it lets you choose a folder name then choose sdcard/sd that is where the phone's linux mounts your external SD Card.
Also I keep my Titanium backups and Nandroids on my Computer for extra safety.
my samsung vibrant is rooted, i used the superone click root, with android 2.2 and it's been freezing up alot when i insert an sd card. Everything worked smoothly for about 8 months, but recently i have been having bad experiences with samsung. i have two external 2gb sd cards and when i inserted the first one, one day, it would finish scanning it and then vibrate once, then three times, the turn black. not off, but black. The button lights would remain on but the phone would become nonresponsive and the phone would remain black for about 5 minutes. Then it would start up like new and begin to scan media. it would stop halfway to freeze up again and the process would repeat. After about 3 more freezes, the phone stopped scanning the external sd card and immediately say blank external sd card on the notifications. it would show a card with a swipe over it. So i inserted it to an adapter and to my computer so save my data but no. The computer wouldn't detect it. I was shocked, all my data lost. I assumed it was just the card so i bought a new one. i instered it to my phone today, after almost filling it up from my computer, and the phone read it easily. after about 5 minutes of finishing reading it the phone stop responding to my touch. Vibrate once, then twice, the the black screen. I immediately removed my sd card. I might be mistakened, but i assume that my phone kills sd cards. my computer can still read it, luckily, but my phone will stop reading it halfway and freeze up just to kill it completely. However without any external sd card inserted, my phone will start as good as new. Any idea why this is happening or how to solve it. I'll try unrooting it only if the android 2.3 update takes longer than by dec. 1 to arrive for my phone. i have my reasons.
I have asked this on androidforums.com as well, but i'm hoping I might get a quicker answer here.
I have a rooted LG P500 running cm7, the usb storage has always worked fine. But last night I plugged it in, the computer made the right noise, the phone picked up being connected, but when I pressed turn on USB storage, it tried for a minute, then stopped trying and went back to home screen and changed my cm7 theme (also started displaying telecom instead of the usual skinny for my network, not a big deal, skinny is owned by telecom, but still strange) a reboot puts the network back, the theme needs to be changed back manually.
I have tried this several times now with the same result each time.
The only thing I can think of thats changed recently is I partitioned my SD card, but of course I have used USB storage since then to put all the stuff back on my SD card from computer.
I have nandroid backup from before I partitioned, but don't want to use that if I don't have to, and not sure if it would help anyway.
Help?!
Try to clear your cache and dalvid cache too
Thanks, have just tried that, and then tried to connect again and its now stuck o the usb connected screen where it is trying to turn on mass storage (frozen, the circle is not going round anymore). I think I am going to have to pull the battery.
Also everytime I reboot my phone now it changes my theme.
I think maybe the partitioning didn't work properly, when I did it I went up to 136mb internal storage left, and now I am back down to 43mb again! Even though darktremor a2sd says that my apps are on sd. Is this why things aren't working properly? Please someone help!
When I unmount the SD card and plug it into a card reader in the computer it says "USB Device not recognised" and something about it malfunctioning. is this normal for a partitioned card, or is something wrong?
Interestingly when I unmounted the SD card it changed my theme and went back to telecom as my network, so obviously the problem is something to do with the SD card, but all the apps etc on the SD card work fine.
Update: Have USB storage working in recovery so situation is not so urgent now.
Still would like to sort out whatever is going on though if anyone knows, I am obviously having some kind of issue since my theme is always resetting to stock cm7 theme when I try connect USB or reboot the phone.
My unrooted Galaxy S3 was working fine until last night, without warning and for no reason, it said my SD Card was blank. Nothing would show up, but occasionally, my photos returned! I saw this as the opportunity to stick my micro SD card into my PC and back it up, but alas...nothing showed up again. So I tried rebooting my phone. My phone gave me a message that it's "In Factory Mode" and gives me a transparent screen with yellow text stating my phone data.
I've removed my SD card, SIM card, battery, and rebooted multiple times to no avail. My phone has not had a single problem since yesterday, but now it just seems like a computer with a bunch of viruses! Any help?
I don't have a definitive answer for why your phone would have started having issues, but I would do a simple factory reset since reboots and battery pulls aren't working. If your phone was backed up with your google account, then it will be less painful when you are restoring your phone. Don't format your SD card yet...wait until you do a factory reset, and if it still gives you issues, format your SD card. Try those things. Sorry if that didn't help much!
Well the SDcard isn't working with the SDcard converter or the card reader, and it's not detectable in any other device. I have a LOT of important information on that card that I need. All of those folders. I simply want to pull that data so I can back it up and get a new SDcard. This seems to be a reccuring problem for Galaxy S3 owners. :\
In regards to the "FACTORY MODE" Error that leaves me with no locked screen or powerdown menu, I had removed the battery, mirco SD and sim card before rebooting. Then the message happened and hasn't gone away for a day. Once again, I am UNROOTED so I'm not sure what is causing this issue!
I'd say if the card isn't readable in any other device, then something is wrong with the card. Not much you can do if nothing reads it.
As for factory mode, I would still suggest doing a factory reset. It is in Settings - back up and reset. You could do it through the stock recovery program since you are unrooted, but it may be easier just using the route in settings above.
I have been the owner of this Samsung Galaxy S9 for about 13 months now, and earlier today my battery died. When I turned the phone back on after partial charging, it acted extremely strangely. It rebooted to the secure boot pin screen a few times, and even to recovery mode a couple of times, rebooting about every 3 minutes. But that isn't it; wifi and cellular refused to connect, the screen would not go off if I pressed the power button, the settings app would not open, many other apps barely works, and the device was very slow for the time it was on.
I did the usual troubleshooting steps, clearing the cache in recovery mode, booting into safe mode, uninstalling recently installed apps, scanning with Knox and Malwarebytes, nothing. But, I remembered the day before, inside Samsung Gallery, there was a little text box before my images that said "SD Card has corrupted information, please back up your SD card and consider replacing it." I didn't think too much about it, or screenshot it. Well, to try something, I removed the SD card and booted normally. The only thing I changed that time was the lack of the SD card and voila, it worked fine. Haven't had an issue since, and I honestly think it might be running better.
For my amateur speculation/hypothesis: I believe when Android starts up, it tries to index installed SD cards. The card I am using is an old Samsung Evo 32 GB card, to the tune of 5+ years. Possibly, with the age of the card, there was light corruption in one folder or cell, and Android didn't know what to do with it. I can't find any corrupted files, but I guess Android hung on parsing the microSD card. I just wanted to share my experience and see if anyone had heard of something similar; I sure cannot find anything on it.
TL;DR: A corrupted microSD card in my Galaxy S9 caused Android to lose most function, and bootloop. Usual troubleshooting did nothing, however, removing the card returned the OS back to normal.
