Tab stuck in endless com.android.keygaurd // setting has stopped loop - Galaxy Tab 3 Q&A, Help & Troubleshooting

I had to factory reset my tab a few days ago since it was in a endless reboot loop (the samsung tab 3 logo would flash on for a few seconds then off then on) until it looped its self to death. I did a factory reboot and now I at least got past the reboot loop from hell but now all it does is keep popping up com.android.keygaurd // setting has stopped with a white or black background. I wiped the chache and rebooted again. Same thing. I let it die then charged to 100%. Same thing. This thing is about to take trip to a gun range or find a home under the tire of my car if I cant get it fixed.
Also this is pure stock. No custom ROM, nothing. Its a samsung from sprint that I bought from someone well over a year ago and have not had issues until about a week ago.

Try deleting the cache partition in recovery. If that doesn't work use odin to reflash your stock os with pit file that wipes and re partitions to stock and let me know

[Q] help please. possibly corrupted efs?

ok so heres what happened. this morning my phone started behaving weirdly. then it restarted and got stuck in a boot loop. I was running the newest aokp release. after the boot loop i restarted to recovery, i was using the team win one. i wiped cache and dalvik and restarted...still only to boot loop. next i tried factory wiping and reinstalling rom. still same thing, only then i couldnt clear the cache. if i tried it would just reboot.
on lunch break i figured id just odin back to stock. after playing with it a few times i got it to flash the stock back. after it rebooted the first time it went into recovery to clear the caches like it should but there was a red message saying cant locate efs or something. there was about 4 lines in red saying pretty much the same thing. and it said manual mode at the bottom.
ive tried wiping caches and restarting a number of times. I fallowed both the guides from the development section and from the general section. so i currently have the stock ics odined on the phone. it will boot to the rom and start. made it through the upgrading android part then once it gets to the home screen it will sit for a minute then reboot again and just boot loop. i can clear cache and make it boot back up but it just restarts after a few secondds.
please anyone know what to do? this is my second gs2.

[Q] Jellybomb start up problems

The problem only happens when I reboot or turn on the phone. When it boots up, I get multiple results. A: It boots up normally (not a problem) B: When it gets to the samsung screen, it freaks out and reboots itself again and again. It's like it's struggling to boot up. One time it got to the gs 3, but then it looped back. C: This just happened today. I booted up and it went pass the samsung screen but when it got to the gs 3 screen, the screen turned a faint pink and it stayed on that screen.
This just happened right after version 8. I know 10 was messed up but on 9 and 11, this problem persisted. Also,I don't think the issue is the phone, since I don't have this problem on other Roms. If I'm wrong please let me know .
Any suggestions, advice, help, etc is welcomed.
Please... i really need help.

I unrooted, went back to stock, it did a factory reset so no bugs should have been alive. I re-rooted, made a backup, did a factory reset and wiped dalvik, then I flashed the rom zip and rebooted. It gets stuck on the Gs III screen. I waited like 5 minutes and it didn't move. My battery was at 50% so I just put it on the charger and tried to boot up and it went through to the set up screen for gmail.Just to see if it was coincedental, I did another reboot but this time it got stuck again. It sounds like a system problem but i'm not sure.Like i said earlier, this only happens on Jellybomb.
Any other ideas?
Edit: I've tried switching recoveries but it doesn't fix it.
Sigh.

Another Bootloop issue

I'm having problems getting my phone past the bootup screen. It first loads the logo then goes to the animated logo then the rethink possible animation and then finally gets stuck on the glowing samsung logo. It then shuts off and redoes the loop a couple of times until it stops with the battery charge up screen and freezes there until I remove the battery.
History: Purchased an att phone for the mb to replace my original phones because it had the insane chip. Had to root it to be able to unlock the phone with my carrier(telus). Since I was in it I flash the DN4 custom rom and everything needed into the phone. The phone functioned fine for about a month and then frequent freezes and restarts started happening. Near the end, the phone was stuck in a boot loop, loading into the DN4 animation boot screen then shutting itself off then on again to endlessly repeat the loop.
Present: At first I was able to get into TWRP and tried some things in there but nothing happened. When there I notice it stated "internal memory 0"-not sure if this means anything.
I was able to flash the saved recovery file from TWRP. Once I did that I could no longer go in TWRP and now have to use the samsung install/recovery.
I have since flashed the stock rom several times with odin and also wiped data/factory reset many times still does the same in bootup. Tried flashing TWRP into phone using odin 3.07 but failed.
What should be my next move? Pretty new at this so I may be missing something very simple or perhaps a dead phone???
Finally got the phone to boot up and run fine. It seems everything was good except the battery was acting up.
Next step is to get the battery to charge when phone is off.
I'll post this question in new thread.

T-Mobile Galaxy Note 2 T889 to Android 6.0.1 Resurrection Remix Boot Loop

i followed this guide
teamandroid.com/2016/03/08/update-tmobile-galaxy-note-2-t889-android-601-resurrection-remix-marshmallow-custom-rom/2/
and it worked perfectly until yesterday
the other day i looked at my phone and it formatted and restarted on its own. i didnt really lose much.
so i accepted it and reset up all my apps and such, and then when my phone died and i charged it
it got stuck in boot loop forever
i tried wiping both cache and reboot recovery it skips boot loop long enough to load up but as soon as i see my homescreen for a second it boot loops again.
so then i tried completely formatting the phone over which worked until this morning when i woke up my phone was dead. swapped batteries and turned it on. booom boot loop again.
is there any advice on what i should do?
im able to format it and get it working again if something needs installed etc
but i want to stop this from happening again
Q: is it possible that a certain app i downloaded is forcing the boot loop? i dont see why it would because ive had all the same apps for months and it just happened out of no where.
i appreciate any help, id just like to know why in the world its happening, and what the best course of action would be
im thinking maybe restore it back to factory firmware and unrooting and starting the process all over again
i seen something for 7.1 would that be better?

Tab stuck on Samsung Logo after flashing ROM

Hi! As the title says I tried to flash a debloated version of the stock ROM for my galaxy tab 3 10 (The one found on this forum). But after wiping Dalvik and regular cache and installing my tablet just gets stuck on the samsung logo. I left it for half an hour sinve usually it takes some time to finally start but it remained like that. I tried turning it on and off I even took out the battery but nothing seems to work. I tried to wipe again and re-install, I went as far as to judt get a regular Stock and flash that. In the end it's still stuck. I didn't made a backup since I am a dumb dumb so any ideas are welcome, thanks.
You have a backup of efs partition?
