Whenever I boot up my phone, it goes through the samsung screens and it gets stuck at the T-Mobile screen. Previously, My SD card caused my phone to reboot, but i formatted my sd card and everything was fine. Now, even if there is no SD card, it gets stuck at the T-Mobile screen. When I tried to format the cache partition, it would look like its clearing the cache, only to show an error screen for about 5ms and reboot. Also, If Possible, I don't want to format my phone. Thanks!

Yesterday I was using my device when it locked up, crashed, and refused to boot back up past the white HTC screen. I tried doing a hard reset, reflashing the ROM and kernel, clearing all the caches, and removing the MicroSD card. Still wouldn't boot.
Finally I wiped the 16GB internal storage, and it booted no problem. I did however lose a great deal of data (I connected he now-blanked internal storage to my laptop and un-deleted most of my data) and I'm a little concerned as to what this might indicate.
I'm running a rooted stock Gingerbread ROM with S-ON. I recently played around with updating to ICS, and in the process made a backup via CWM backup/restore, which I reverted to about a month ago, and after wiping the internal storage last night. When I restore this backup, it goes through the whole process with no problems, but at the end it says that there was an error restoring /data. The phone however, still functions normally after restoring.
So I bought a new SD. I copied the contents of my prevoious SD to the new one using minitool partition magic. After turning the phone on, it wouldn't boot past the slimbean logo. So I removed that SD card and put the old one back in. Same thing. Cleared cache and davilk and not it goes past it but gets stuck at "starting apps". What could have happened?
Tried wiping cache + davilk + fixing permissions, no luck.
Edit #1: Sorry, the question form didn't save the "This is a question post" tick after I previewed, I hope that doesn't mess up things.
Edit #2: I should also point out that I backed up everything previously, so I don't care about saving any data on the phone, I just want it working again...
Edit #3: I keep forgetting some small details, the phone wouldn't boot even when removing the SD card.
Hello,
Two days ago I decided to try the SD Link feature from Link2SD on my Galaxy S2, because I was tired of running low on internal storage space when I had a 32gb SD card just for photos.
I was only linking games and other apps that were not important to the phone's normal functionality, but on 3 our 4 occasions Link2SD would hang on the linking process and I'd wait 10 minutes before force quitting the app each time. This wasn't causing any problems, until the last hang. I restarted the app and saw that it couldn't compute any of the other apps internal size. So I rebooted the phone and got stuck on a boot crash.
Sometimes the boot would go beyond the Samsung logo and into the Cyanogenmod loading, but the phone would shutdown before leaving that screen.
I had CWM on my phone, so I tried a bunch of stuff:
to wipe data/factory reset
wipe dalvik cache
wipe cache
reinstall Cyanogenmod from a zip (either from internal, sdcard0, sdcard1, and even Odin)
After so many attempts, my searches started pointing me to the fact that some system files could be bad, so I tried:
format /system
format /data
I didn't format /boot but it's reaching the point that it's the only thing I haven't tried.
So next I used Odin to flash back to stock ROM, and in the process lost CWM.
Since that didn't work, I flashed a stock Kernel too.
I should point out that the phone was working perfectly before this Link2SD mess, and also that each time I flashed with Odin, I would get a glimpse of the app optimization process, that would reach around 39 of 42 apps before the phone would shutdown.
I'm running out of ideas and search keywords.
Please help.
Thank you for your time.
Hey,
I'm using CM11 ROM with my I9300.
My phone has a boot loop problem. Few seconds (about 20~30) after it turns on, it goes off.
The problem appeared suddenly, after a night that the device was charged.
Tried deleting cache / dalvik cache / data and didn't succeed.
I'm sure it isn't a problem with the button because on recovery mode I can stay for long as I want.
Thanks
EDIT: I'm not sure I actually succeeded with wiping data/factory reset. when i click on it in the recovery (CWM) it says "wiping data... formatting /data" and turns off 2 seconds afterwards. Is there a way to factory reset the device through PC?
If possible,try making a complete backup on external sd card. Then, wipe data,system,cache and everything else. Next,download a rom suitable for your phone model,copy to external sd card,and then go in custom recovery. There install that rom from external sd card.
Just remember, don't wipe out external sd card,remember to take it out before every wipe. You don't want losing things from your external sd card.

Hello, greetings to everyone here,
First of all i am sorry because of my lack of English vocab in typing.But i really frustrated within this bootloop problem in the end.
I have samsung SCH i759 , and i tried to root, 2 times, using Odin on first trial, after i downloaded Samsung USB driver, CWM md5.tar and SuperSU update.zip then failed and succeed when using VROOT, then installed android partition and Link2SD app in play store.I even created some links to move apps to SD card for more internal space.
works fine until few hours ago, i decided to change the partition space on Android Partition into 4 parts ,between FAT32 and then changing EXT4 into EXT 2 and adding exfat then swap, then i forget to unmount sd card before.
then i get error notification, then phone is lagging, then restarted.
Since then i lost apps i installed and moved to SD card.
then i decided to unroot Via VROOT PC. and then reset to factory , and now what i get is worse than before,
now phone is keep on recovery boot mode, i tried some advices on web, from keeping hard reset, take off battery, until wipe cache, dalvnik cache. etc. but something strange, when i enter the "Wipe data/factory reset"
the options list is just "NO" instead of "YES"
now,it keeps loading into recovery mode from samsung logo with yellow triangle below.
this is my last effort before i will send it to service centre. i really hope seniors here will give advice for this problem.
regards,:good:
