Hi guys
I always wondered how to know if your phone is stuck in a bootloop and did a lot of research of my own and found that if the phone is stuck in a bootloop the LED of the phone and the screen will not dim after a certain amount of time . Bootloop is the problem when your phone doesn't start, it remains on the boot sequence


Bootloops are mainly caused because system files interfering with each other which causes instability and/or crashes at the boot sequence.*To find the cause of a bootloop you have to think about what you did before getting the bootloop.Choose one of the following reasons that caused the bootloop for you and try out its solution.- After flashing a new rom

*If you flash a new (base)rom with odin your /data will be kept. This means your old dalvik-cache will be used for the new system files which would result in a bootloop, to fix this problem:
1. Start your phone in CWM Recovery
2. Go to Advanced
3. Choose "Wipe dalvik-cache"
4. Now go to "Mounts & Storage"
5. Choose "Wipe /cache"
6. Reboot your phone if the problems still exists after doing that and you're sure it's not related to the rom, then you need to do this:
1. Start your phone in CWM Recovery
2. Now go to "Mounts & Storage"
3. Choose "Wipe /data"
4. Choose "Wipe /cache"
5. Reboot your phone
Wanna go back to stock firmware see below

1 Open odin 1.85 download here

2) Shut down your phone completely and make sure it is unplugged from ur PC.

3) Enter download mode by holding down the Volume down and center button and turning on the phone.

4) Press Volume up to continue

5) Run Odin on ur PC and select F. reset time and auto reboot and click on pda and browse for your stock firmware tar or .md5

6) Connect your phone to ur PC and Odin will detect ur phone and the COM ID turns yellow.

7) Click on Start and let Odin flash your phone. Wait for the Green Light and let ur phone restart.

Personally I never experienced boot loops after a cwm restore.. restored cm10 to ICS and vice versa.. and if I ever ocassionally got a boot loop then the regular wiping always solved it..just my personal experience..

There are plenty of situations in which the screen dims and LEDs flash up, but the phone is still in a bootloop.

Hi Adam, nice to see you here now regarding the point if the phone is taking too long to start, it definitely is in a bootloop ^_^
