Hi peeps, short background story first....HTC Sensation was running jelly bean.....you know how it is...after a while you get bored so i installed CM11 ... after trying to sort the battery drain issues i was having i thought id go back to jelly bean until i found CM12 for sensation and thought id give it a go......this is now where my problem started...installed the rom and gapps .. phone booted past the HTC screen..then the little blue cyanogenmod man thing....then i got the android starting message box.....then i got a message "Encryption Unsuccessful" reboot phone and do a factory reset.....ok.
Now whatever i do i cant get into recovery tool... if i just reboot phone it goes to the Encryption Unsuccessful message....if i go into recovery mode i can get a few different results as follows...
1. changing to fastboot boots the phone to Encryption error
2. recovery tries to start up 4ext recovery tool...but all i get is a 4ext screen saying booting 0...1....0...1....0...1....0 etc forever until i take the battery out
3. as above with the SD card removed i get booting 1 2 3 4 5 6 7 8 9...1 2 3 4 5 6 7 8 9....etc until i take the battery out
4. factory reset does the same as 2 and 3
dead phone??? or fixable.... please help!
thanks
Unbrick my heart....
please

Hi,
So my SGS2 Skyrocket is stuck in a boot loop. I've have the Sky Icecream Sandwich ROM installed for a few months now, and haven't changed anything recently.
What is happening is my phone with vibrate every 2-3 seconds with a blank screen. When I take out the battery/power source, and put it back in, the phone shows the Samsung splash (not the Android splash) for a few seconds, then goes blank and does the vibrating again.
I've tried plugging it into the computer, but the power it gets from USB turns it on and into the boot loop, so I can't get it into any kind of recovery mode. I also tried the Vol+Home+Power key combo, with nothing.
Any idea what could cause this/what the course of action should be? Thanks!
Turn phone on and wait 2 hours. If it wont work do what you use to do when you booting recovery mode. (home screen i guess). But hold it longer.
Good luck
nathan-96, do you have any idea what caused this? Because what's concerning me is that it's not getting past the Samsung icon (before android starts actually booting).
When you say turn it on, do you mean just put in the battery? Because the loop starts right when I put the battery in, it doesn't wait for me to press anything.
No, I meant turning it on. Hold centre button and put battery in. Just hold it for a moment. Hopefully you will reach recovery.

Can you access download mode instead of recovery? If so you could try re flashing something with Odin...
Definitely try getting the battery out for a few minutes and boot the phone while maintaining the combination to enter recovery

AT&T Skyrocket BOOT LOOP Cyanongenmod 10
Hi ,
I´am playing with my Skyrocket to run the Cyanogenmod 10 and always I got stuck at Boot Loop .
This is what I have and did :
- Running AT&T Stock ICS 4.0.4 UCFL6 rooted ( I have a back up of this)
- CWM 6.0.1
- Cyanogenmod 10 Nightly Dec 07 , but I also tried with Cyanogenmod 10 Stable
- Gapps
- Factory Reset / wipe cache
- Wipe dalvik
- Mount/storage format system
- install using CWM Cyanogenmod
- install using CWM gapps
- Mount/ storage format cache
- reboot
I also tried to wipe twice as other threads say.
So I´am still with the boot loop
I returned my backup to the ICS ...
Thanks in advance !!!
Skyrocket Bootloop
Whats happening is the power button acts as if its being pressed. Thats why you have the bootloop and the phone turns on as soon as you put the battery in.
Try repeating pressing the power button or hold the power button without the battery for a few seconds. :fingers-crossed:
I have the nexus s 4g flashed to boost mobile. it has ran great for over a year now. i have flashed many roms and kernals to it and it has worked like a charm with only the occational hickup. but a few weeks ago when i would power it down and change may battery it would start to get stuck on the google screen. i could pull the battery a few times and it would eventually take off and work fine for a few day and then do it again. this last time it done it i cant get it to go past the google screen for nothing. i can get into the fast boot mode and also into clockworkmod touch recovery but when i go into flash zip from sd it say error loading sd, when i plug it into my computer it conects when in fastboot but i cannot access my sd memory at all. i tried the pdanet but it wont work due to no access to the sd. i downloaded the program wugs nexus tool kit and tried to flash stock and unroot with option bootloop / soft-brick in my boot loader. the program seems like it is working, it takes control of my phone restarts bootloader a few times then says restarting your now stock phone, but my phone just sits in bootloader. i have tried to manually reboot system and it just goes to the google screen and stops. when i power on my phone the google logo comes up, flashes away for a split second then pops back up with the leds at the bottom of my phone on this time but thats all i can get. please help i dont know what to try next. let me know if any of you have had this problem before and what you did to get it fixed. Please help i miss my Nexus...
** UPDATE *** Well i havnt really given up on my Nexus but i gave in and bought a new Galaxy S II so i could have a working smart phone again. Ill still be working on the Nexus in my spare time so ill update if i have any luck.

Hi guys,
I have spent 2 whole days searching XDA for a solution to my issue with Samsung tab 2 10.1 GT-p5100 3g on vodaphone uk (although i think its unlocked).
I have tried so many ideas from the forums but now at a last resort i have given up looking and conceded defeat. PLEASE HELP.
Device info
Samsung tab galaxy 2 10.1 GT-p5100 3g
Direct issue:
stuck in boot loop, it turns on and goes to the Samsung really noisy splash screen then reboots - AFTER trying to install a stock Samsung ROM that i suspect might not have been good. (apologies this is a project i am revisiting from a few months ago and i cannot find the ROM). It appears to not have an OS on at all now.
I have tried using ODIN to put this on: EUR-P5100XXDNA1-20140602152511 which fails at about 50%
I have also tried using sd card from boot recovery to use these zips:
ASerg.2.P5100XWALE2.NoWipe.zip and samsunggt-p5100.zip from the forums
nothing has worked and i have been stupid and not fully documented everything i have done plus left a 2 month gap between working on it.
Any way all i want to do is take this expensive paper weight and put an image that will work so my daughter can play angry birds!
please point me forward although i have been through the forums at least twice.
thanks

I have had bootloop many times, once I couldn't escape it and instructions on this website helped me:
h t t p://howtorootmobile.com/stuck-in-android-boot-loop-tips-to-fix-recover-from-boot-loop/.
If instructions below won't help, try to find stock ROM from another source, like
h t t p://samsung-updates.com/device/?id=GT-P5100
and flash it with ODIN.
If ODIN fails, maybe this link can help:

Fix Android Boot loop issues on Stock Android
Step 1. Remove the battery from the device and wait for 30 seconds and then put the battery again on your device. If your phone doesn’t has the remove bale battery like Nexus 4, then power down the phone and keep it powered off for 5 minutes. This will turn off your device permanently.
Step 2. After that Boot your device in to Recovey Mode. Samsung Users use Volume Up+ Home + Power keys. If you have the other Android device then do a Google search how to enter in recovery mode.
Step 3. Once your android device is in Recovery Mode, Go to the “wipe cache partition” option and select it.
Step 4. After that go back to the recovery main menu and reboot the device by “reboot system now” option.
Step 5. If the device again stuck on Android Boot Loop pull out the battery again and repeat the above steps. This time also “wipe data/factory reset” and then reboot device.
Now your device will come out of the Android Boot Loop and at the first time the device will take some time to reboot.
Fix Android Boot loop issues on Rooted with CWM Recovery Android
Step 1. Follow the Above guide (Fix Android Boot loop issues on Stock Android) Step 1 and Step 2 on your device.
Step 2. Once your Rooted device on recovery mode, go to the Go to “Advanced” and Choose “Wipe dalvik-cache”. After that go to “Mounts & Storage” and choose “Wipe /cache”. In the end go to the main menu of recovery and Reboot your phone.
Now the Android Boot Loop should be gone now. If it still persists, do the following on your device. Go to “Mounts & Storage” and Choose “Wipe /data” after that Choose “Wipe /cache” and now reboot your phone.
So today after a doctors appointment i checked my phone to see the time. when i got home my phone was stuck in the google screen. i waited for about one hour as i had to go some place else. when i came home the phone was still in the google screen. at this point i could still go in to recovery mode. i searched a bit on the internet and then flash+unroot from the nexus toolkit from the stock 5.0.1 that i had to the stock 5.1.1 . it still didn't open. i searched some more and I found that i needed to enter recovery mode and wipe everything off. i tried making a backup with the toolkit but it didn't work. then i tried going to recovery mode and it also didn't work. next i tried to flash a 4.4.4 version as i saw it worked from someone but it is stuck at the point "waiting for device" .
i don't know what to do. please help me fast , i need to leave town in 4 days and i don't have time to take it to service and i don't have a back up phone either.
your help would be much appreciated
edit: when i try to enter recovery now the phone shuts completely down
edit2: my nexus toolkit apparently didn't flash properly so atm i have no os on my phone. (it is confimed by a twrp recovey i booted with the nexus toolkit) i am currently struggling to find out how to install and os without recovery mode or toolkit, help would be appreciated
edit 3 : if anyone is reading this, i manage to boot a recovery image but it only shows an android robot with a red exclamation mark, i cant use adb commands, it says device not found, still don't know what to do
if i try to install os with a flash-all.bat it says failed remote flash write failure, same as with the nexus toolkit
if i try to wipe cache from the trwp recovery it says taht i cant mount any partition so i think my memory drive is busted
Hello, thank you for using XDA Assist.
Try asking for help HERE and the Nexus 5 experts will help you there.
My guess is that you need to unlock the bootloader to use the flashall.bat
Have Fun!
