[Q] Samsung Galaxy S2 Skyrocket - Bootloop

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:

SiyahKernel s3-v1.8.8
Posted on January 13, 2013
Changelog
rebased on i9300 update7 sources (sudden-death issue is supposedly fixed in this source drop)
reverted temporary fix for exynos-mem exploit as i9300-update7 sources already fix that
cm10.1 is now supported in dual-boot configurations
1.8.7->1.8.8: fixed cm10.1 not booting when installed as 2ndROM (a tiny typo in ramfs)
BUT,it doesn't work anyway (just trying now at it's stuck on the boot screen)
Just try it and report back! :good:

You do realize that the siyah kernel is for the international S3 which has different hardware then our s3? If you are using a kernel for a different phone then of course it wont boot....

By "International", you mean the exynox version unlocked right?

Flash problems
I've had installs stick at the boot animation or shortly thereafter several times. Usually it's because of a dumb mistake. The only thing that's consistently worked for me is flashing back to stock VZ firmware via Odin and doing the whole process over from root through installation. It sucks but it always works.

Howdy.
I've just flashed CyanogenMod 10.1 - 20130315 to my droid 4 with Safestrap, and I haven't been able to boot into it; the cyanogenmod splash screen with the rotating wheel graphic shows up, but it spins for upwards of 40 minutes without doing anything.
I followed the guide on the cyanogenmod wiki for the droid 4 device. The forum won't let me post a link to it.
Before I installed I wiped / factory reset, and after install I wiped cache/dalvik; still no dice. I've tried doing the same process several times (even wiking the system before trying to reflash), but the same result has always occurred: ever unhelpful eternal wheel...
I'm a bit at my wits end; I haven't been able to find any other information about this that wasn't solved by wiping cache / dalvik, so I turn to y'all for help.

Same here
I installed Cyanogenmod 10.1 with CWM the link:[Recovery/Bootstrap][5-sep-2012] CWM Touch recovery v6.0.1.1 - xda-developers and i went ahead and installed the mod: cm-10.1-20130211 all went fine untill i noticed that my camera is not working (not a big deal) but then i noticed that my phone only saw 488MB out of my 32GB this was un acceptable after i found how to connect my phone to my pc so it showed up as a storage device do that i copied the same mob but a different version (cm-10.1-20130129_v2) so i went ahead and booted into Android system recovery <3e> and i did a factory reset and then i said oh f*** i need CWMR to install the thing so i just waited for it to do its thing and then reboted the device thinking after i boot up i will reinstall CWMR but i was never able to boot because im stuck on the boot animation. Been waiting for +20min or so and nothing please help me what can i do this is my only phone please help

help with CM10.1 ROM issue
Hi folks,
this is my first post on XDA. I have a Sprint htc EVO 4G LTE phone which was running on JB.
Thought of root and flash with CM. So, first I unlocked the bootloader using htc dev and installed TWRP custom recovery and then rooted.
Then I flashed the stable CM 10 then flashed gapps which is compatible for CM 10 version. so far so good. oh, btw I did nandroid backup before flash and also wiped to factory reset, cache and Delvic cache.
After the flash i clicked on reboot system and I see the Cyanogenmod boot, but its stuck at that stage and I waited for more than an hour. No luck.
Thank god I did back up before this, otherwise not sure what I'm gonna do.
But, could someone tell me why it gets stuck at this point. I know some of you guys had this problem. I searched everywhere but didn't get help. I thought of posting this in android development forum, but as a newbie I can't do that.
Please help me out.
P.S: when I'm on boot screen (power button + vol down button) I see unlocked at the top but I also have TAMPERED in red color on top of that. Was this normal? or do you think that is causing the problem? and what should I do now?

(First of all I am not an expert)
It happens sometimes about 1/10 of every flashes I did with cm10
It might because some files didn't get copied or got corrupted.
Just try this method
Format data
Format system
Format cache
Wipe dalvick cache and factory reset
Now flash the ROM
Hit thanks if I helped

(First of all I am not an expert)
First wipe every thing(system,data,cache,dalvick,android secure....)
Now install ROM,
Wait don't install gapps
Now find an extended cm10.1 kernel or lupus kernel(or such kernels) for your device and flash it via pc
I prefer flashing kernel after installing the rom

Ask in the Xperia X10 mini forums.

Three-finger salute
Ran into this situation today when I tried to restore a backup and I couldn't get past the CM10 logo on bootup. Holding down all three buttons, power, volume up and down, got me back to the Clockworkmod boot screen.
ETA: Sorry, posted in wrong forum. My situation pertained to a Samsung Galaxy 5 Media Player.

Can't Boot Into Recovery.

I'm having an unusual problem for me I've not came across this before, I can get my tab 2 - 5110 to boot into download mode but not recovery mode, It will boot to the rom normally when I shut it down completely to the charge battery animation will it boot up normally. If I try restarting the tablet by holding in the power button then releasing it at the samsung logo it just goes to a blank black screen also kies nor odin recognises my tablet its a very unusuall problem for me and I've tried everything I know to try fix it but with no success so far, I was running phils touch recovery and brolees 3.0 themed rom, my tablet worked perfectly until I tried to install brolees 4.0 over the top of his previous one the 3.0 which I thought would have been straight forward, at first it wouldn't get past the samsung logo but I worked out if I can get it to shut down to the charge battery animation it will boot normally but it reloads the apps everytime, anyhoo if anyone has had a similar issue or knows what stupid mistake ive made I would really appreciate any help, thank you in advance!

[Q] Bricked my Blaze

About 9 months ago, I bricked my Blaze, and after giving up, I've been using a new phone in the interim.
Here's what happened:
Battery dies while flashing some rom, get boot loop, fix by flashing stock rom etc.
Flash Kit Kat Rom, phone immediately shuts off when unplugged, works fine plugged in.
Flash stock ROM, infinite boot loop, can get in the CWM recovery, but flashing stock rom, etc. dont stop boot loop
boot loop description : SGSB4G T-Mobile 4G Green Android Rocket Animation --> Glowing Samsung Logo ---> Repeat
I've tried numerous solutions since then but none have worked.
Please help. Winner gets $5.00 paypal bc this is literally the only problem I've never solved.

Your battery is probably bad, replace it and you won't have a problem.

I will see if I can try out a new battery at the store and test the results.
I have been skeptical as to whether the battery was the issue, as the boot loop animation would still work when it was unplugged.
Thanks for the response!
