Hi, my phone went crazy today and now stuck in a boot loop. Is there any way to backing up my data before reinstalling firmware with odin? My boot loader is locked and not rooted. No custom recovery.
See if it will go into safe mode...
You can try clearing the system cache but I doubt this will help.
I may be wrong but otherwise your options are limited. You should always backup your critical data redundantly. If you have a SD card and used it as a data drive, your data be intact more than likely.
Install or uninstall any apps lately?
Any recent updates?

Thank you for your reply. No new apps or updates. Phone was working... took a picture and put it into my pocket. When I grabbed it out of my pocket it was in an infinite loop. I removed the sd card and wiped cache but no help. I mainly wanted to try and retrieve my texts before attempting to fix the loop with a firmware update. Oh well I guess I am SOL.

You're welcome.
Factory reset to fix. It's likely the user data partition* that's corrupted.
Try getting it to go into safe mode, sometimes it takes a few tries. I wouldn't sweat the texts, mine repopulate after I do a reset. Either way I don't consider them critical data
*SEU, single event upsets are rare but can happen at anytime. No hardware damage is done if one occurs but the corruption of a critical byte of data can have consequences.

It's so weird. I updated the firmware and still had the boot loop so I did a factory reset and now the phone will not respond to any hard resets or anything at all. Just my luck.

You'll need to reflash it to the version it was on. I would have attempted the reset first. The system partition may have been corrupted.
It could be a possible hardware failure if the reflash fails.
That's my guess.

Hi There,
I have been having the Samsung Galaxy Sl for 2 months now and the software kept crashing. I went to privacy and opted for a factory reset. Funny thing is no matter how many times I do a factory reset the phone restarts, and installs all the apps which i personally installed again. This is not a google recovery problem where all data is backed up in google. But the apps just magically reappear even after formatting the internal sd in recovery mode and reflashing it to the latest firmware. I am at a loss. I got a shock that even after reflashing my firmware to the latest 2.3.4 JKPJ5 it still reinstalls apps such as AVG, the BBC News, Cool reader.. And even my old wallpaper again.
Steps I have taken:
1) Formatted internal sd
2) Used recovery mode and wiped partition and cleared cache
3) Did factory reset and even installed a new firmware.
I have done everything. Pls help. My home button is also not working and the all the corrupted data from my old installation also comes back
Even when I restart my phone, any new apps i install vanish and are again replaced by the old apps.

Did you try factory resetting with the code? That should help you! And please post this in the Q&A section henceforth!
Sorry. Moving to Q&A

Thanks.
Funny thing is i tried the reset codes. And only some work. I tried the reset code *2627*3855# . But I get an error saying its a connection probelm or invalid MMI code.
Sorry bangalorerohan. But I am not getting any replies in the Q&A section. I will just continue here for now..
Tell me the method you used to flash the new FW! I will tell you your error!
The probelm began before I even considered flashing my firmware. The sd card will be unexpectedly removed causing forced closes. Did a factory reset using the privacy menu quite a number of times for a few weeks. It helped for a while but the problem will always reocurred though. Then suddenly, factory resets stopped working alltogether. The phone will delete new apps i install every time i reinstall them and reinstall apps which i uninstall every time i restart the phone.
I thought flashing the firmware will fix the problem. But even after flashing the old apps and settings keep coming back.
Here are the steps I used to flash.
1) Removed sim card and micro sd card.
2) Restarted phone in download mode.
3) Run odin and plugged phone in Usb port
4) Checked Repartition, Auto Reboot, and Reset Time boxes.
5) Downloaded pit files.
6) Waited for it to pass
7) Pressed reset
8) Took phone out from usb port, took out battery and turned on download mode.
9) Flashed PDA, PHONE, AND CSC files. By ticking Auto reboot and reset time checkboxes.
10)Clicked Start
11) Waited for pass and started again.
I even tried using the recovery mode to wipe everything but still had the same problem. Apps and settings still keep reocurring from the corrupted android 2.2
I have done everything and am hoping for a solution for this frustrating problem. THinking of reflashing to android 2.2 and sending my phone to samsung for warranty.

I think you have done everything correctly. Maybe it's a hardware problem because your sd card keeps unmounting. Have you dropped it? They best way is to send it to service center for repair.

reflashing back to froyo
Hey guys thanks for your help. but the problem seems to be related to the hardware. I am reflashing my phone back to froyo and sending it to get the warranty. But after reflashing there seems to be another problem. I cant receive calls anymore. But i can make calls..
I need to know if samsung can find out if I have reflashed my phone because I am afraid that my warranty will be void. Is there anyone with experiece regarding samsung warranty?

play dumb, dont mention you flashed, tell them you tried to update with kies and since then the FW is acting up, you can't make calls anymore etc
Interestingly... i have exactly the same problem. I have had this problem for abt 4 months now and i have tried everything (except sending it back to the repair centre). I don't think its a hardware problem but more of a bad flash somewhere in between.
i have been searching the net for ages for a solution... have yet to find any.
Hi all:
I've got the same problem!!
Has any one a solution? I'm crazy with this.

Can anyone suggest a troubleshooting method without a factory reset. This is what I am experiencing:
Everytime I reboot the Sensation will boot up and go through the normal process. About 3 or 4 minutes it will just reboot. Often when this happens I note that I don't have to re-enter my pin (a clue?). This rebooting will go on repeatedly but eventually (if I leave the phone alone) I will at some point end up with the phone up and running.
There are no random reboots, it is only this situation that causes the problem and it's obviously some point 3 or 4 mins into the process that is causing the problem.
I've noticed that if I reboot to recovery and then select reboot from there it is usually successful.
I am s/off via wire trick method, and rooted. recovery is 4 ext and I am still on stock rom.
I'd like to find out what is happening at the point of the reboot, is there a good way to do this?

Hi,
Have you installed a new ROM recently?
Did you fully wipe the phone before you did this?
If not,try re-installing the ROM you are on.
No wipes.
You will not lose settings or data.

What I noticed is that the problem didn't exist when rebooting from ADB or fastboot either.
Anyway your suggestion so far looks promising. I've tried a normal restart from the phone and a battery change both of which would usually end up with the rebooting problem. Both of these tests haven't caused it so I'll keep testing but thanks for the suggestion.
What is does the Dalvik cache do and how would this have caused this kind of problem? I'm interested in the whys. The problem appeared soon after installing a couple of things as I remember and I did try to backtrack without much success.

Revived thread - as it's happening again
I'd like to revive this thread - perhaps I should post a new one but since it's here ...
This problem has returned with a vengeance. It took me about 3 hours of fighting to get this phone to stop rebooting. It seems clearing the dalvik cache isn't a solution anymore (if it was in the first place).
What I've observed is that if I take the sd card out it doesn't reboot. When the card is in I have several shortcuts on one of my home screens which often will not refresh for ages (ie. android icons for anything moved to sd card). When the icons start to appear the reboot will happen shortly after. All the time I'm waiting for this to happen the phone is very sluggish.
I don't think this is an incompatible sd card but maybe it is, however, if I can get this to stop rebooting then all is ok till I attempt another reboot.
Ideally I'd like to track this down to find out if there is an app which is misbehaving. Are there any tools that can help me do that.
Any suggestions would be most welcome.
Backup all your data and do a factory reset
This problem might be due to 3rd party app as you phone without sd card dosent reboots
Might be some of ur app is seriously miss-behaving
After a factory rest install each app n check ( I know it's time consuming)

Yeah hoped to avoid that for 2 reasons. 1) It's a bummer 2) I won't know what the problem was / is.
I did do a factory reset after backing up data via my recovery. It seemed to be ok but I had nothing on SD at that point. I loaded a couple of apps and moved them to sd and it still didn't happen. The I restored the data and it was back to the same problem.
I may have to go with your suggestion but I'm going to lose some data as I can't back up selectively (so it seems).
Is there a logger I can use that starts at reboot. If I could find out exactly what it's doing when it decides to reboot I might nail the app?

hi
greetings
to find the problematic app might go tough you will have to install each and every app and check after that
try installing all the trustworthy apps before eg. file manager,fb,twitter,gmail etc then check once again ,after that install single app at a time
16 GB black Nexus 5 on ART with stock recovery, stock kernel and rooted using CF's autoroot and bootloader unlocked. The phone was running perfectly for the past 3 months.
Now it has started to randomly reboot all the time and goes into bootloops which take a while to recover from. It seems that the power button is super sensitive. Even touching it mildly brings up the power off option. After reboot the phone went back to Dalvik runtime from ART.
I've been running Dalvik every since. I've uninstalled most apps. But the phone keeps on rebooting again and again just randomly in the middle of tasks. After this the phone goes into a boot loop until it boots successfully. It's almost impossible to use the phone right now, because the reboots just happen more and more frequently.
I've tried wiping the cache, uninstalling apps etc. Nothing has helped.
Any suggestion? Thanks in advance.

Sounds to me like a hardware issue-as if the button is partially depressed at all times. You could try popping the back off and blasting around the button with compressed air. Another option would be to RMA.

Thanks for the quick response. I don't want to mess around with the hardware of the phone. I think I will go the RMA route.
Do you have any suggestions in terms of the best way to backup the phone? Do you think a factory/data reset of the phone might help before RMAing?
I'd factory reset just as a precaution as your phone probably has some personal info on it

Yes. I will definitely factory reset before RMA.
Any idea on the best way to backup the phone content? Should I flash all system files for factory reset or just use the phone's menu?

Upload photos, music and videos to drive, dropbox or to your computer with usb. Then depending if you're rooted or not helium or titanium backup for app data. Me personally I'd just flash all files cause it doesn't take long to do so. Good luck and hopefully your new Nexus gives you better luck
I really need help! Friend was messing with my phone and selected to factory reset it. I quickly grabbed it away but it already began to reboot, however I did not let it reboot. I forced it off.
Any chance I can still stop the factory reset process? I have TWRP installed but seem to be getting the factory reset splash screen when I hold volume down+power.
Has the damage been done, or not yet? Please tell me there's a way to bypass the reset. I do not have a removable battery.
Get to recovery mode and backup your phone and reboot. That's the last option I guess

If you turned off, you already stopped it. It will not try to continue when you reboot the device. But, there is no way to know if anything was wiped or not, until you reboot the device and find out. If it wiped anything, it's gone, unless you can use any of the various data recovery programs on PC to recover the lost data, if it is possible to retrieve it.

I heard that the factory reset is "locked" into your phone as soon as it turns off, but it doesn't begin the process of wiping until after the first boot. I think I have partially confirmed this because when I try to boot, I get the android updating splash screen, which I guess means it is about to wipe. I force it off as soon as I see that screen, but before the phone has time to officially begin any process, so I am unable to boot into android or recovery.
Is there a way to mount my internal partition to my PC without turning the phone on, like through fastboot?

The reset was already started, you originally interrupted it before it could "finish" the "wipe" then, when you rebooted, it is starting the "reload" process(android is upgrading) where it loads the system and whatever personal data is still there, if any personal data remains from the interrupted wipe.
As I said, all you can do now is let it finish booting, then use data recovery software to hopefully retrieve your lost data, or take it as a learning lesson if the data is irretreivable.

get the latest firmware from sammobile.com/firmwares and flash it in Odin with the CSC not the HOME_CSC. Let the normal CSC file do its job and wipe everything from the phone, make it revert to 100% stock and re-setup the phone as you see fit
I confirm that G955F ****sung restarts randomely without reason.
The solution above didn't help.
I'm able to watch 30 minutes long movie on YouTube then I put the phone on the table and within few minutes it just reboots and stuck on ****sung logo.
The worst mobile I ever had, really.

while im glad that doing this helped, im equally (if not moreso) confused as to why. I havent deleted a text in probably 5 years. Well, i guess ive deleted one or two here and there, but i have texts from years and years ago on my phone that have been passed from phone to phone. There would be even older ones if it wasnt for accidental wipes from time to time.
