[Q] [P5210] As soon as it boots to Stock Recovery, it Reboots!

I've got a Galaxy Tab P5210 that's stuck in a constant boot loop. I flashed it with the correct stock firmware from SamMobile using Odin, but it fails to boot properly. It automatically boots to the stock recovery screen, but the problem is it will instantly reboot as soon as it reaches this screen. I see the dead android with the red triangle and exclamation point for just a second, and it instantly reboots. Is that normal? I don't think that's normal. From what I've been reading, this screen is supposed to stay there until you push the volume keys to bring up a menu, but it reboots so fast that I don't have a chance to even push anything.
I've tried flashing it with other recovery images. I tried using CWM, and it almost worked. With that, as soon as the tablet booted, I'd see the CWM splash screen, and it would instantly reboot. Similarly to how it's booting now but with stock recovery.
I'd like to point out that I've never messed with anything like this before. I work in a computer/small electronic repair shop and a customer brought it to me. She ended up getting into stock recovery and a friend of hers did some serious damage in there which prevented it from booting properly. Normally we don't mess with things like this but, with it being how it was, I figured there was no way I could make it even worse than it already is by working on it. I thought if I flashed the original stock firmware back to it, it would fix it, but that looks like a no-go since it's still booting the same way it was when she first brought it to me.
Is this thing completely broken or is there still hope for it?

No - it should be recoverable. However - any data will most likely be lost.
When you flash with Odin, make sure only F. Reset Time is checked. Use Odin 3.07. Make sure again that firmware is correct before you flash. After it flashes, power off and then on again
Latest KK firmware for the US version of the 5210 is P5210UEU0CNK1_P5210XAR0CNK1_HOME.TAR
Good luck. If you're trying to root, then there are threads in the 10.1 Dev section that should help

M,
this firmware was always my goto for device recovery/restoration https://www.androidfilehost.com/?fid=23060877490005046

Not interested in rooting, just wanna get the stock firmware back on. Maintaining data isn't a necessity, the customer just wants it back in working order. I tried using that firmware, but I had Auto-Reboot checked.
EDIT
Yeah, it's still doing the same thing. When I first boot it up post-firmware flash I see an Android with a loading bar underneath it, and then it reboots. When it boots again, I see the same Android and then it suddenly changes to the dead one with the red triangle. Maybe I'm just doing something wrong here with the button presses following the flash?
EDIT2
It looks to me like the stock recovery image is just broken, since the tablet just automatically reboots the instant it attempts to load it up. Flashing a new firmware replaces that though, so I don't know how or why it would even be corrupted. Odin reports no errors, so I don't know what's going on. And every guide I'm reading with fixing bootloops all say "go into stock recovery and clear the cache", but I can't even boot into stock recovery. It's like it's not even there. And I know it's not a power button issue causing it to shut down, I can power the device off fully with it, and it will stay off until I press it again. I'm banging my head against the desk here.

What if you flashed a TWRP recovery in Odin. Then if that's successful, boot into recovery and wipe/format everything except ext SD, Then try the ODIN flash again with filr your stock tar

I'm having the same problem and that didn't work for me. It shows the twrp splash screen and reboots. I'm looking for the .pit file it has to be the recovery partition right?

[Q] F240L Stuck in recovery, won't boot to system or anywhere except to the recovery.

I was on stock F240L20D, 4.4.2 Kitkat, rooted, PhilZ Touch 6 installed. I've tried some ROMs before but reverted back to this one. So, basically, I've been to the recovery several times, but only used the ADB method to access it, and I've made several backups too.
However, one thing that happened today has frustrated me completely. Long story short, I thought about making a backup again, although this time, I used the power keys to get to the recovery instead of the ADB method, backup completes successfully, nothing wrong just yet, but just as I tap on 'Reboot System Now', it boots back in to recovery.
I've tried everything, tried using all the ADB commands, even going through all the options in the recovery, but it always seems to boot back in to the recovery. Really can't figure out what's happening. Any help would be extremely appreciated.
UPDATE: So I've flashed a KDZ, the Lollipop one using the LG Flash Tool. It's taking a bit too long to start, currently stuck at the U+ Lte logo. I hope it gets fixed.
UPDATE 2: It says Android is upgrading, YES YES!!!!! This is so exciting, but I'm still not convinced.

With most of cwm version after 6.4.7, any time you use power + volume up to access the recovery, you will get the boot loop. Go here and down load the zip file from the first post. Flash the zip and you should be go to go.

MM 6.0.1 Xposed Update!

So, i recently have tried flashing Xposed on the MM 6.0.1 on G920P a.k.a Sprint S6
( ALL_SPT_G920PVPU3CPB6_G920PSPT3CPB6_CL7280193_QB8664149_REV02_user_low_ship.tar )
I have root and recovery, but Xposed doesnt seem to comply with me.
from multiple sources or builds.
And each Xposed file that i've tried so far that i've been flashing over and over again, rinse and repeat.
( Flash Stock through Odin, Go through setup process on the phone, Reboot Back to Download mode to Flash TWRP, Reboot, Back to TWRP to Flash Xposed, Once flashed i Restart it again, back to the s6 screen to becoming a black screen bootloop, thus having me restart the whole flashing process again )
from android file host website. And Default xda unofficialy build on this website.

It would go from the Galaxy S6 Boot Menu startup to black screen and bootloop back to the original BootMenu or screen.
NO LED cycles nothing, but i can access Download Mode and Recovery But Updating Nor Uninstalling doesn't do anything to the rom, it just keeps boot looping unless i Flash the Stock back into place.
I'd like to have Xposed working i havent found a version for me that would work for this but i would really appreciate if everyone could help out.

Did it work. Ive only noticed a tad bit longer boot up the 1st time but all good.

i've tried most of them and i tried v80.0 or v80 and i got one part success half i didnt which was from it i got to the LTE spectrum screen and it just would go past that before it would just be the led flashing and bglank screen, i waited about and hour and still nothin changed from that screen.

Nevermind i made an update

This is what i've managed so far.... what am i missing here?
So here's what i"d take place in order to attempt a flash of Xposed Framework.
I start with Pre- Downloading the files for the MM 6.0.1 Stock Rom, it's in the forums Somewhere.
TWRP ( New_S6_Spr_TWRP_MM_Bootloader2 ) a.k.a 3.0.1
(This is a special version only for the Sprint SM-G920P and is meant to be flashed with Odin)
SuperSU 2.68 a.k.a ( BETA-SuperSU-v2.68-20160228150503 )
and obviously, Odin ( Odin3 v3.10 )
The steps that are taken place.
1st. I'd Boot my device into download/odin mode.
or
( while the device is powered off, i press and hold the home+power+volume down buttons.
and from there I'd be taken to a light blueish screen saying "Warning", and i follow through by pressing volume up)
2nd.
Once the device is in download/odin mode, and ready to go, i'd take my phone, plug it into my windows PC and open Odinv3 and from there
i'd select in odin, or i'd click the "AP" button and select the, tar file.
After that has been flashed thoroughly, I'd then proceed with the follow on screens, the 1st reboot and it updates or it says
Optimizing app 1 to 30.... the 2nd reboot where the hand free activation commences and
from that 3rd time it reboots and boots up again, i'd follow up with my login information.
3rd. once my device has been fully booted from the 2nd part, i'd then shut it down or restart it into "download mode again" and connect it to my pc again
and from there i'd load odin, and search or i'd find where I downloaded the special "TWRP .tar" or recovery file
and select the "Ap" option again and press start Afterwards.
After it flashes, right when its done i automatically hold the home+power+volume up buttons,
turn the device off and hold home+power+volume up and your should get some red text in the upper left hand corner with recovery not enforcing, that's okay dont be worried,
and from there it should boot into and be brought into TWRP...finally lol.
Now that's where you can flash SuperSU
4th. I'd leave my phone connected to my pc until, it's fully booting into twrp or i'd just connect it once im in the recovery.
I let my pc detect my phone and i'd copy both of these files.
SuperSU 2.68
and
Xposed
4th. After its copied, i'd go back into my phone, i tap install, and i select supersu and let it run, afterwards, i press reboot.
And let it sit for about another 2 minutes to do its own thing. Afterwards. once the phone is fully booted up.
I'd then go back into recovery, and flash Xposed and i'd wait about another 2-3 minutes for it to cycle
from the LTE Spectrum Screen to the, torquise colored screen where it's finally optimizing apps from 0 to 331.
5th. Once done, i'd finally have my advantage to install what i'd like which i'm doing as of right now still testing it out.
P.S if you do what i do for the SnapPrefs Module then i'd take in high note that before you flash the Xposed to download latest Snapchat 9.26
log in, once logged in then proceed with the rest and download XInstaller to downgrade from 9.26 to 9.17.1.0 to take full advantage of Snapprefs coolness.
upon note so far, after installing the modules, i rebooted my phone and it boots until it hits the LTE Spectrum screen and it has a light blueish pusling cycle and im stuck here.
maybe i can try another version. to be continued...
If you need any help feel free, i will try as best as i can, as i am a n00b but i have plenty of free time and have some decent knowledge about this.

After , i went back into recovery, i went to uninstall xposed thru the other flash file and its says optimizing 0 to 36 items and it booted so far, mayber after i flash the cache again and reinstall i should be fine but until further notice...tbc

Alright after a good amount of time i;ve finally concluded that the versions i;ve tired from xposed were the ones from the OFFICIAL thread and id always bootloop with that puling blue led and black screen, BUT with Wanams Xposed Version 80, and 79 they worked EXCEPT i can only get to the LTE SPecturm white boot screen and it does nothing from there BUT when i flash 80.1 it completely pulls through with the boot and completes but i had forgotten to mention that for some people on aanother thread that Xinstaller may leave you with bootloops and as it did for me thats exactly what happened. But i m still confused as to why the officials dont work by wanams does even after wiping cache,and dalvik cache multiple times and uninstall and reinstalling xposed.

Does yours still bootloop or did it finally pull through?

At a loss... SM-920P, MM, continuous reboot loop no matter what

I upgraded to MM back the beginning of the month, tripped my Knox bit (I had rooted via PingPong root on Lollipop), but I was eager to go to MM and try Xposed so I could improve the horrible battery life.
I had the system working fine, rooted using CFAR, and no problems. Randomly, about a week ago, it just "lost" root. I wasn't sure why, and CFAR from Odin wouldn't bring it back. I did a flash with SuperSU in TRWP yesterday and it worked, and I did a NANDroid backup, saved it to my computer, and installed Xposed... On a stock ROM.
And my phone has been a continuously rebooting brick ever since, no matter what I do.
So, I've tried everything I can think of. Because my data was completely backed up, I did a complete wipe, and nothing. I tried flashing the Xposed-uninstaller.zip and that supposedly worked, but the phone reboots about 53 seconds after it starts up, continuously, no matter what.
I've tried the default MM firmware, tried letting it go through it's paces on its own (but it just reboots every 53-57 seconds), and also tried with a fresh clean default MM ROM, which does dump TRWP, then restart into the default bootloader, have it dump the cache and do a complete re-wipe, and nothing. Still restarts.
With the stock MM firmware load, the first boot it always stops at 32%, reboots, and when it comes back up it sometimes makes it through "optimizing xx of 30 applications" but always reboots and comes back to it over and over, ad infinitum. Sometimes it makes it to 30, usually it doesn't, but it always fails, reboots, and comes back to the same menu on a stock ROM.
ADP and MTP in TRWP work fine, and all my data is backed up. So, I'm willing to do anything to the device; nothing left on it to care about (I already tried NAND erase in Odin and format partitions in TRWP). It still continuously reboots at around 53 seconds.
I've also tried custom ROMs loaded up from TRWP (Renegade 1.1 and TeamSPR V3). They apparently load - everything looks/works great from inside TRWP - then invariably they reboot at about the 53 second mark. Can't even get Renegade past the boot screen.
Nothing was done hardware-wise to break it; the Knox bit flipped three weeks ago, and the SuperSU upgrade had been working fine. The action that killed it was attempting to install the Xposed framework on a default ROM that only had SuperSU installed. But I've since installed a default ROM and ran the Xposed uninstall to no avail. The uninstall Zip in TRWP gave all the right responses that it worked, but it still rebooted 53 seconds after restart. Continuously.
I don't even know how to go back to Lollipop because attempts to load G920PVPU1AOCF in Odin gives me an immediate failure of "SW REV. CHECK FAIL. DEVICE: 3, BINARY: 1," so downgrading appears to be out of the question.
Someone has to have seen something like this before or there's something I'm missing. About the only thing I can think of is to try a custom ROM install and force the Xposed framework again without even letting it boot up (because it won't anyway) from a TRWP install. I'm going to attempt that while hopefully someone else comes up with ideas for me...

rebooting
people have had luck letting their phone battery die completely and rebooting after charging just a little bit. make sure its completely discharged before rebooting

Stick it in Odin mode and let it die, once it gets to the point where you cannot turn it on anymore, it's good :good:

This doesnt quite seem like a boot loop... Help?

So my phone has been perfect for over a year. Within the first month of owning it I rooted, installed TWRP, and jumped on CM13. Been updating nightlies all year long once every week or so and enjoying the phone. Its really been perfect. Tonight after work I jump in my car, throw it on my car charger, and drive home. When I get home I notice for some reason I have no cell service (Emergency Call Only) so I reboot. That was the end. The reboot got stuck on the CM boot screen flashing the circle out around the CM face over and over and over. So, I pop the battery, try again, same thing.
Well, being that I have rooted and flashed for years now I figured Id wipe dalvik and cache. Tried that, same thing. Did a full wipe and reinstalled the nightly from my SD card. This time I thought I made progress as it set up all the apps. Then it just hangs on "starting apps" and then it sits there forever. Never boots. Doesnt loop or restart or anything, just says its starting apps.
So, jump on here and find the bootloop issue. My serial is 505x so I was wondering if maybe thats my issue. Decide to download the all in one flash zip from here...
http://forum.xda-developers.com/tmobile-g4/development/stock-h811-20i-images-kdz-flashable-t3308227
and I flash that. Stock rom works without any issue. Fired it up, logged in, no problems. Huh. Do a restart and even though I flashed that file it still shows bootloader unlocked as the LG logo comes up, and boots into TWRP as normal as well. Figured well I flashed a stock rom, lets give CM13 a try again. I download a fresh nightly through my pc and transfer it over via usb so I know its good. Full wipe, flash, reboot, hangs at "starting apps" again.
Now I am lost. The stock rom sucks and my love for this phone is based around what it is with CM installed. Am I missing something here? I really want to get back to CyanogenMod and away from the clunky slow stock rom.
Any input is greatly appreciated. Thank you all.
EDIT: Well went through the Android setup steps after flashing the stock rom so I would have a phone until this was all figured out. Turned out its not working. After setup I am not getting "Process System Isn't Reponding: wait or close" No matter what I do the phone is so slow or laggy I cant use it. Its trying to download my apps and restore my phone from my Google account but it just hangs up. No idea what to do at this point. Is my kernel messed up? Its a totally clean flash. What the heck. 3am, I give up, hopefully someone has insight in the morning. Thank you all.

You really have to investigate by adb. Look into the dmesg output and logcat as well. Maybe your sdcard is corrupt or 100 other issues are possible as well. What device do you own? H811? unlocked?

There are several users reporting that the latest cm version bootloop the best option is to start in download mode and Flash with LGUP Stock ROM.
You could also try to boot into Download Mode and then flash the latest twrp and then Boot into Factory Reset Mode again
