[Q] Boot loops

Recently I flashed RebelRom Beta 2, it resulted in a the LG logo being displayed on my phone but nothing would happen. So I did a restore from CWM, and the restore worked fine for a couple of days but at some point my phone lost power. Now whenever I turn it on I get boot loops and am unable to get into CWM. My question is is my phone bricked, and what can I do to avoid another brick? (Note I never formatted /data and I always follow installation instructions.)

It's a known problem, at this point the solution is to restore you back and don't shut off your phone. Reboots work fine, but shut off will boot loop it.

Hmmm so I can't turn off my phone. What do you mean by reboot/how do I reboot? Also does this mean I can't flash roms anymore? And finally is there a fix on the horizon?

[Q] Infinite boot loop out of nowhere.

I was using my phone earlier today and was attempting to extract an archived file with OfficeSuite 7. I had merely 400-500 of free space available at this point. After a few attempts and cancellations due to failure to extract I decided to restart my phone. Upon restarting it continuously will vibrate, show the Samsung logo for a moment, the screen will flicker off and it loops through that process all over again indefinitely. I can access download mode and recovery mode. I tried clearing the cache through recovery and removing the battery as well as smacking around the power button but it did not fix the problem.
I'm using stock TouchWiz Android 4.1.1 partly debloated, rooted, and stock recovery (because this ROM reflashes the stock recovery after a reset if a non stock recovery is installed).
I figure a factory reset might be the fix but I would need to extract my apps, settings, and SMS/all other data and I'm not sure how to do this with the phone in this condition and without an external SD card. Maybe I could flash ClockWorkMod, do a nandroid backup, and than extract this data with Titanium Backup? Can Titanium Backup do all that I am asking (I've barely used it)? Does anyone have an idea as to what the cause of the problem is to have this suddenly happen? I'm thinking it's the power button malfunctioning. The day prior twice my phone turned itself off.

Twrp has built in file manager. Copy to sd, then to computer?
Otherwise look into ADB.

what is happening
strange I am have the same issues . from working great to now FC and rebooting . almost like it the power button malfunctioning but it is not. Its something more. I was running DocHoliday 4.3 and was great . then I tried Aamir Mod V2 UVDMD5 4.3 same great . but this morning noticed it kept rebooting for no reason . wiped reset, nothing . looped and looped . wipe/reset and re-flashed and it will only stay on for a mintue . and if sleeps will not turn it F/C as soon as I touch power button.. crazy ???
anyone having the same problems with any 4.3 ROMs ??

I'm having the problem on my S3, but I'm not on 4.3 yet....
I already had this issue once 2 weeks ago and I factory wiped and started over. Fast forward two weeks forward and it started again today. WTF?

Are you using TWRP? I had a similar issue, upgraded to newest TWRP 2.6.3.1 and it was fixed. Before this I tried everything, factory reset/modem upgrade/different roms.. and it wasn't working..other than a rooted touchwiz rom.
Give it a shot.. might work..
As per Perseus71:
Install TWRP 2.6.3.1. Then take a Nandroid.
Next wipe /Data. Then flash your Custom Rom. Wipe Dalvik + Cache after the Flash.

[Q] recover data - phone softbricked

My Note 2 froze on me yesterday while using it and then restarted. However, it stopped at the Samsung Logo and never proceeded to boot back up. I removed the battery several times and attempted to restart to no avail. Phone is still not proceeding past Samsung logo. Phone has been rooted with jedix16 using a perseus alpha kernel. Anyhow, the most recent nandroid backups I have are from several months ago. I did manage to take a backup after the phone became bricked but not sure if that will do me any good. Is there any way to extract data from the backup?
The files in the cwm folder are .dup and .img files. The only data file is data.ext4.dup. Am I hosed as far as grabbing any recent data is concerned?
Thanks in advance

You can use adb.exe to pull data if you can get into download mode

Stuck on Google Screen - Restore Didn't Work

Good Morning All -
A few days ago, I dualbooted my N7 with Ubuntu. The installation went fine and the tablet was working with no issues over the last several days. Last night, I was using the tablet and set it down. I went to pick it up (roughly 5 minutes later) and the touch screen was unresponsive. I was at the lock screen but couldn't get it to unlock. I pushed the wrong key-combo first and the device took a screen shot.
I was able to reboot into fastboot and attempted to go to recovery. The device would just hang at the Google logo. I pushed a factory firmware update from my Ubuntu system and attempted to reset -- no joy. This morning, I used Nexus Root Toolkit from my Windows 8 machine to see if I could get it up. Root Tool kit worked fine, pushed the images over again and restarted but it continues to hang at the Google logo.
Looking for any other advice folks may have on getting the device to boot.
EDIT: I can get to the bootloader fine and the computer recognizes it.
Thanks!

Alright... I just attempted using NRT and flashing 4.4.2 instead of 4.4.3 to see if it would run through. No joy, again. Remains on the Google screen.

Im having the same problem with an unlocked unit. I would bet if you tried to do a factory reset in the android recovery menu it would give you a huge error all having to do with cache.

I'm unable to get into the restore menu. Hangs at the Google logo when attempting to get there.

I've tried about any solution I could find... Bumping one last time before I torch the unit :\

Nothing can be done. Its something inside. If its the 2013 model, call and get it rma'd. Sorry man.

Resurrecting this thread to keep a work log.
I made have made some progress but hitting another roadblock. I've been holed up at home due to an auto accident so I started tinkering with the N7 2013 again.
Using the Nexus Root Toolkit, I am able to launch "Boot Temporary - Custom Recovery" from the advanced options. The problem I now run into is TWRP's touchscreen will not work. I attempted to do volume up/down to see if I could select but it wouldn't. The software is not frozen as I can see the temperature changing.
Anyone have any thoughts or information on how to boot another custom recovery that uses button inputs? I appreciate any input.
Updates:
1. I was able to push TWRP via "fastboot flash recovery." It went to the Google Logo then loaded TeamWin screen. I started to see errors when the program launched. "Unable to mount..." multiple times then the device rebooted. Device stuck on the Google screen.
2. Shut the device down, booted back into Fastboot. Selected Recovery and it began loading again. This time, the app launched and worked. Touchscreen does not work but the CPU temp is fluctuating and minutes tick up.
Update 4:49PM Central:
1. I am able to install and boot into TWRP 2.8.0.1 through TWRP 2.7.1.1. Those versions load but of course touch screen does not work.
2. I have been unable to get CWM to load... It installs fine but I cannot boot into.
3. The factory recovery images also do not load.

Samsung Galaxy Tab S stuck in bootloop after flashing official ROM and factory reset.

After recovering from a previous bootloop issue with my Tab S, I'm in the same situation after flashing the official Samsung stock ROM for KitKat 4.4.2 via Odin.
When the ROM was first flashed, the tablet began working as per normal with the exception of it taking 10+ minutes to fully reboot and the device somehow restarting itself and loading the display within a second. However, after a few days, I kept receiving pop-up windows on the tablet stating that different applications (most of them I didn't have opened or running in the background at the time) weren't responding. A couple of days after that, more of said pop-up windows kept appearing on the screen, sometimes freezing the whole device until a push notification appeared in the background or the device force-rebooted itself.
I flashed the ROM again once or twice and cleared the cache partition to see if that made any difference, which it unfortunately didn't. I also removed the microSD card and SIM card, force-rebooting the device without them, and then with them when that test failed.
Now, for roughly about a week, the tablet has been stuck in a bootloop (the splash screen animation) where I have left it to drain the battery, leave it for about a day or so, and recharged it to 100%. So far there hasn't been any success.
Today I finally factory reset it to see if that may help, and the only thing that has changed is that the sound of the device rebooting is now playing when it does transition to the loading screen, which I had turned off previously when the tablet was still working.
Is there anything else that I may have missed that could help it work again? It's not rooted (and I would very much prefer to keep it that way) and has not had a custom ROM installed or flashed onto it. It can still enter Download Mode and Recovery Mode, but other than that and being about to use the Power-Volume Down technique, there's not much else I can do with it so far.

Factory reset, install stock firmware, wait ten minutes and you should be good.
But why kitkat? MM is available and working well.

It worked! Thank you so very much!
And I'm not a huge fan of updating my Android devices due to past experiences, but if this happens again, I might just update it to Marshmallow.

@ashyx
i love you man...this worked for me too...thank you...now i need to reinstall TWRP again and see what's cooking......

I had this problem recently too, with the added complexity that the "Factory Reset" option in recovery wasn't working -- it would say something like "MDM does not allow factory reset" and then just reboot.
Fixed it by directly flashing TWRP with heimdall, then booting into the new TWRP recovery, performing a factory reset, and then rebooting the OS. This time it got pass the bootloop.

i flashed new twrp for T700 it's bootloop cannot enter the twrp menu keep bootlooping ...what's the solution for this?please help

Help ME!
What are "stock firmware" and "MM"? and where to get it?

I've replaced the power button thinking it was a hardware issue but now I'm not sure. I've also installed a few different stock roms but still have the same problem. Does anyone have any insight as to what could be going wrong and what I can try to get it fixed? Thanks for any help you can give. The device is a Samsung SM T-800
