[Q] Stuck in Boot Loop - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hello
Have a GS3 running Rootbox 4.2. Was running stable for probably around 6 months, no issues at all except for the occasional random reboot which seems to plague all S3s.
Felt it vibrate in my pocket, assumed I had a message. But when I looked it was restarting. It gets to the rom loading screen then abruptly restarts.
Now it even doesn't get that far. The samsung screen shows up and the phone restarts in a loop.
Cannot stay booted into recovery. CWM recovery screen shows for about 2-3 secs then phone restarts.
Download mode through odin works, but I'd like to avoid wiping everything if at all possible.
thank you for any help.

an easy try to fix is to pull battery , wait a couple minutes and then either just hold power button till vibrate or do button combo to get to recovery.
"all i can really do , is stay out of my own way and let the will of heaven be done"

Try re-flashing an updated version of CWM via Odin and see if you can remain in recovery mode.

Thanks for the replies
Tried pulling battery for few mins (actually a few days since I did not have time to mess with phone) - No good, phone gets partway through the rom load screen then reboots.
Tried the odin suggestion - home +vol. down+ power opens download mode, but download mode stays open for around 10-15 sec before the phone restarts itself.
I have tried swapping back to the oem battery since i have an extended battery and the problem still remains.

Sounds like a hardware problem to me since you can access download and recovery but it turns itself off. You've tried a couple of batteries so that kind of rules out any software issues.
Did you try booting the phone with a de-brick image from XDA?

[Q] Bootloop, recovery won't load and restore mod turns off

Trying to fix my daughters SGIII Sprint phone.
This morning it started going into a bootloop.
What I've tried:
1) Attempted CWM recovery by pressing (VOLUP+HOME+POWER). The screen flashing "SAMSUNG" with in small blue font in upper left "Reocery Starting..." And then the phone shuts off right away.
2) Attempted ODIN recovery by pressing (VOLDOWN+HOME+POWER). Once in download screen in ODIN I try and flash KIES_HOME_L710VPBLJ7_L710SPRBLJ7_329968_REV03_user_low_ship.tar.md5 but after a few seconds the phone just shuts off.
All in all I think if I can just get the phone to stop shutting down while in download mode I can at least flash something and this thing back up.

Okay, so I had this problem and at the end of the day I had to turn it in to Samsung for warranty purposes because the phone would automatically turn off when on and then restart the boot process and turn off again. However, I found a temporary fix, if you pull out the battery wait for a while (like an hour) and put it back in, the phone should stay on longer so you can flash through Odin. The phone will no longer turn on normally because once you start the flash with Odin the boot.img has been flashed but it's a broken flash due to the fact that the phone turned off in the process.
Here are simple steps:
Take out the battery and leave it out for an hour or so (longer won't hurt)
Get the USB plug and make sure it's in the computer and Odin is started with the correct tar file already selected so that you can flash it quicker
Put the battery back in and start the phone in download mode
Connect the phone and just let it sit for a couple second to make sure it stays on
If it does stay on for more than 15-20 seconds then you can begin the flashing process
If it turns off while in download mode you can take out the battery and put it back in (you don't need to wait)
It's really all just a matter of patience because eventually, the phone should turn on for long enough
Once flashed, the phone should work for a while
So after following that process, I got the phone to work for about 2 months but the issue reoccurred. I was eventually able to flash the stock rom but the problem persisted. So I called in to Samsung to turn it in for the warranty. So far, they have "Replaced a component" in my phone. I SHOULD have it back by Monday. :fingers-crossed:
Thanks, for the response. Battery is out now so I'll try later this evening after it sits for awhile.
I hope it works for you. Just as an update, Samsung has fixed the problem and my phone has shipped as of today! So I guess it's an error on their part.
No luck yet.. Going to leave battery out overnight and try again in morning.

[Q] Galaxy Tab 3 stuck in boot cycle after root

Hi Wonder if anyone can help?
I downloaded mirror beta from the app store to mirror my Galaxy Tab 3 SM-T210 to my apple TV3g.
Once downloaded i was informed that the device had to be rooted, so I used Kingoroot and followed the instructions. Everything was fine during the rooting process and completed informing me that it was successful.
The problem is after this the Tab is stuck in a constant cycle mode of the Samsang GALAXYTAB 3 boot logo.
I have managed to power it off ( Black screen) but have been unsuccessful in getting the device into recovery mode to try an hard reset.
I have tried all the button combinations I could find on Google but it only just shows the galaxy screen. Any help would be much appreciated since it is my daughters tablet and ill be in a valley of it if I cant get it restored.
Thanks in advance
Have you tried to Boot your Tab into Download mode?
If this working , flash Stockrom with Odin.
I'm in a similar situation with the logo boot loop except I am unable to shut it down. I hold the power button for 10 seconds and it reboots right back to the logo again with no shut down. How can I shut this down?

I got in the same situation trying to root my Tab. I wound up holding the power button down a really long time and then gently releasing; then I booted it into recovery and there is an "unbricking your 10.1 " post on XDA that has a stock 4.2.2 link.
Once you get the thing into recovery, and it took several attempts (like for two days)- I had given up and was thinking I had finally truly bricked an android) I got it into recovery and then used Odin to flash the original stock rom and it worked. Then Samsung almost immediately downloaded the OTA and I was at 4.4.2 stock.
The sd card slot is broken, so I am still trying to get the tab rooted, but for now just having it functioning in stock form is better than that Galaxy emblem slowly flashing every 5 seconds until the battery dies (Itried that too, thinking it may somehow recharge and reboot and something would be different-no such luck)
But I found holding the button down persistently made the difference, at least it seemed to.
Good luck

I9195 (8Gb) on charge overnight, dead the following morning?

Hi guys,
I left my phone on charge overnight and in the morning it was off and wouldn't switch back on.
A debrick image allowed me to get the phone into ODIN download mode (i couldn't get into the recovery mode though).
I have tried several different roms and now (i think) its on a stock 4.4.2 rom.
Odin seems to flash the phone without any errors but upon reboot shows "Booting Recovery..." then gets stuck in a boot loop.
I have even tried CWM - Odin seems to flash it without a problem but when it reboots it just shows "Booting Recovery..." and gets stuck in a boot loop (I have tried the Up Volume + Home + Power with no success).
Since it was on the stock rom and has never had a custom rom on it (until lately trying to fix it) it seems likely that the flash storage is dead or has bad sectors?
Any ideas? I have never had a phone die like this before
Thanks
I have exaktly the same problem and i think we are not alone.
Have you tried all usual things e.g. battery pull?

Soft-Bricked M9

I've had an M9 for 2-3. After the first year I got my phone, I installed a custom recovery and rooted it but later uninstalled root and custom recovery. It has been fine ever since except recently. Last month, my phone randomly crashed for the first time and got stuck in the infinite bootloop. It was as if everytime it tries to boot up, it crashed during it. If I hit the power, vol up, and vol down button, I make it to the screen with the option to go into recovery, download, etc. But when I actually try to go into either bootloader, recovery, or download mode from that menu, it crashes and goes back to the white htc logo. I've have gotten the phone to bootup a couple times by leaving it in the freezer as it tries to boot up but after using it for 1-5 minutes, it crashes again. If I don't use the phone at all, then it usually wont crash. After a day or 2, the phone fixed itself. Then one morning, my notifications got stuck together and my screen became unresponsive. So I took my death sentence and restarted my phone and now my phone has been doing the same exact thing for a week. I don't know how to fix this problem because getting it crashes trying to go into recovery and trying to do a factory reset is risky since it could crash during the reset. If also manage to make it into safe mode thinking maybe an application or virus is causing this but the phone crashed in SAFE MODE so I don't know what the problem is. I doubt there is any saving this phone because is probably a hard ware problem but who knows. Any help would be greatly appreciated!! Thank you.
Flash back to stock. Stock firmware fixes all sorts of issues.

HTC M9 Stuck on Bootload After Battery Dropping to 0 Fix/Work Around

Hi all,
My phone is rooted (still S-ON)(TWRP installed) and running viper's ROM. Last night I forgot to charge the phone when I got home, when I looked it was 1% and shut off. I plugged in the phone and foolishly tried to reboot right away instead of waiting a good ten minutes. Well the phone never got out of the HTC logo screen. I would hold down the power and it would vibrate twice, no clue what that mean't. Anyways I waited for at least 10 minutes to give the battery a chance to chare and see if it rebooted but it didn't. Finally I was able to get into recovery doing the following. Hold down the volume up and power button till the phone reboots (screen will be black) Then quickly hold volume down and power until you see the HTC logo on the black background. Then you should have the options to boot into recovery and into twrp. I had to do a data wipe as something in the OS got hosed. I lost all apps and SMS but at least I was able to boot back into the phone. Hope that helps some out there.
I have encountered this same issue on 2 phones but couldn't recover either without reflashing a stock firmware.
