Confounded with this t210r - Galaxy Tab 3 Q&A, Help & Troubleshooting

I am trying to fix this t210r tab 3 7" for my mother-in-law. I have no idea what's wrong with it. It boots up, loads into its normal stock operating system but then in 5-15 seconds it reboots. Factory resetting it in recovery mode does not actually reset it, not sure how that works... It looks like it resets, but then when it reloads, everything is still there, nothing was deleted or reset. I can't root it or install any custom roms or kernels. I've tried five or six roms from this site. If I try turning on usb debugging once it restarts, any changes made are no longer present. I've run out of ideas. Can anyone help or offer any suggestions?
Thank you very much.

HOX Won't Boot

I need a bit of help with a stock HTC One X. As of this morning it won't boot up. I have made no changes to the ROM, everything is stock.
Tried entering the recovery panel and turning fastboot on then restarting but every time the system stops at the "HTC One" page after making a startup sound. Sometimes the screen will go black and hitting the volume keys will bring up the volume changer but that is it.
There was no warning of an OTA update or anything like that.
When charging the screen stays on and dims, but stays on the "HTC One" screen.
Factory reset HOX and it booted, but next day same issues. This is 3 times I've had to factory reset now.
Every time I restart or cold boot it freezes on the "One X" screen.
This exact same thing has just happened to me! Just 10 minutes ago
I have no idea what to do.
I have not attempted root or anything like that everything is stock (Optus from allphones).
All I did was restart and now I cannot get into the phone.
I can get to those options (fastboot) by holding down the volume down button and the power button but restarting it or powering it off there does not help.
I havn't tried a factory reset yet as I'm scared about loosing all my data.
Can someone please help!
Please please
I'm suprised someone else is having the exact same issue what the hell is happening
Have you tried using the Recovery option from the Bootloader?
Yeah I tried that.
It didn't do anything. I've since done a factory reset. That worked but I've now lost everything
Now that's it's allw whiped I figure I might as well root it and install android revolution. I hope it's just a software thing and this will fix it.

Fair enough, if you're thinking of Rooting and installing ARHD etc then feel free to use my Guide : The Stock to Custom ROM Awesomeness guide
It'll take you from Stock to having ARHD on your phone ok

Took it into HTC last night and had the firmware flashed. No problems now... 12 hours with numerous restarts just to make sure.
It looks like it was a corruption in the software. I noticed HTC turned off the fast boot option before giving the phone back to me. Took 30 minutes in total.
If it happens again, try to hold the power button and the "Homepage" button at the same time. You should see a grey box saying "Continue holding to restart".
Thats a full restart rather than a shell restart.
That may help.

[Q] Problems setting to stock

I have a little experience with custom roms and rooting, but i have not yet set anything back to stock. I tried to set my GT-S7560m back to stock with a stock rom from sammobile(dot)com. I flashed it with odin like normal, and it said everything was good, but the phone never booted.
It got past displaying the model but got stuck at the samsung flashing while booting. I have left it at the screen for 30 minutes hoping it would boot, but no luck. I removed the battery for a day and tried to boot again and still no luck.
I read somewhere that sometimes help if you can clear the cashe but i can not enter the recovery(I can still enter download mode). I have noticed when i try and enter the recovery when the phone is plugged into the computer it just keeps saying disconnecting and reconnecting, with nothing on the phone it self.
I also tryed to use samsung kies to reset it but it just told me this device was not supported or something similar to that.
Now i have tried anything that i have found, i am willing to try just about anything, any help or input would be appreciated.

Fire Phone Won't Go into Download Mode

I'm not entirely sure if this is where I should post this, but I am having a problem with my Fire Phone and I really hope you guys can help.
So, story time. I was thinking that I wanted to install a new ROM on my phone just to try some new things. I decided on the SlimKat android 4.4.x ROM and I installed it with GAPPS using SafeStrap 4.01. However, the new ROM was not working correctly so I thought I installed it wrong. So, I read up a little bit more on this and it said that I had to do a factory restore beforehand so I did it with high hopes that it would work. However, it sill did not work. What happens is that I power it on, it asks whether I want to go into SafeStrap or not, it continues if I say no, and they it starts with SlimKat. After about 20 seconds, it stops the starting animation and starts its boot loop.
Since I factory restore it, I had no back ups or and ROMs that I could install on my device. I try to plug it into my computer but it is unrecognizable even if it is the recovery. I also tried going into download mode, doing it multiple ways, but with not luck. It still goes into the boot loop. I factory reset it multiple times but still with no luck. Within SafeStrap, I tried to wipe it, but it is unable to wipe the Dalvik Cache or Data. If there is any way that I can move the stock ROM onto my phone, it would solve all my problems. If any of you have any ideas, please let me know.
I having same problem. Unable to go to recovery mode in normal way, but I could managed to go to recovery by attaching it to computer with usb cable and keeping pressing power + Vol up key for few seconds.
Then I tried Factory restore, Adb Sideload original file downloaded from amazon, but the problem still not solved.
My phone is keep flashing amazon logo in loop.
If any one have idea please help.

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

Hi all. I have a problem with my tab 3. It just keeps rebooting. I have checked the battery and looks OK.
I have tried resetting in Android but does nothing.
