Hi...I've searched everywhere and I haven't seen anything close to my issue. But if there is and I missed it I apologize in advance and I appreciate any help/advice.
Well I rooted my phone from 4.3 with no issues. I used safe root so it wouldnt trip knox. I flashed sokp's 4.4.2 ROM with the proper gapps and agni kernel. My issue started after I tried updating my camera with photosphere 4.3. I went to use the 3d feature and it shut my phone off and started to loop. Also flashed the camera fix zip but that didn't help either. I got into recovery using cwm and wiped everything from the cache to data, almost to the point of no service. So i flashed beanstalk 4.3 rom hoping it would solve problem but it didn't. I even did a factory reset (didnt work) and found a rooted stock ROM I flashed thru Odin then back to beanstalk, all to no avail. Now I have to keep my phone plugged into a power source in order for my phone load past "sgn2" screen. And if I unplug it then it resets phone and loops. I also noticed that with beanstalk I have no kernel(well it reads unavailable). I was thinking that maybe after the camera failed that some data or something maybe corrupted. Is there a way to wipe everything to the beginning, like fresh from at&t, so It will stop looping and I don't have to keep my phone plugged into the wall?
Also with mean bean I can uplug my phone for a few min before it resets but if I try to open any apps it resets. It seems as though my phone isn't getting enough power.
Again all help is greatly appreciated
I just received a replacement I747M. It was running android 4.4.2 I747MVLUFNK2. I rooted and flashed recovery. Even before I installed custom rom the phone would not boot with the stock firmware unless the phone is plugged in. When plugged in the phone will boot and work fine. Whenever the cable is removed phone automatically reboots, and will start boot looping. Return the cable and the phone works fine. I tried flashing back to stock with a sammobile image of the same firmware. I also tried installing a custom rom and experience the same issue. When I flashed back to stock firmware phone took forever to load and didn't seem to get past the splash screen after waiting for over 10 min, however it was able to boot without the power cable plugged in. Any advice here would be appreciated.
Thanks
Update: I have re-flashed to stock successfully but still experiencing the boot loop problem when not connected to a USB power source. There is no reboot in recovery or download mode. Again plugging the USB cable into the phone resumes normal boot and operation. Only when the cable is removed does the phone restart.
Update #2: Turns out it was an issue with the battery. Trying another battery seems to have solved the problem.
Rooting the I747MVLUFNK2

Hi there,
I have the same phone as you (I747MVLUFNK2) and can't find any Xda post on how to root it... How did you did it?
Thanks
Is your phone still under warranty? If not, flash a custom recovery and install supersu from recovery.
I just recently Odin the NJ3 tar over my ND8 stock deodexd debloated ROM a couple of weeks ago. Then I started experiencing that the phone will randomly shuts off automatically and the only way to turn it back on is to plug it into a power source.
So I decided to flash the Stock+NJ2+Deodex.zip using Philz after doing a wipe to install a new ROM. This caused the phone to only boot to the Sprint Logo and then it shuts down. So I decided to wipe and install Wicked S5 Xperience V2.2. Now I am at where the phone will only boot and runs if it is plugged into a power source.
Can someone suggest a solution or steps to get my phone back to stock (including all the needed downloads)?
Can I restore a backup I made prior to updating to NJ2 (while still on ND8)?
Can I install the ND8_STOCK_DEODEXED_ROOTED.zip after upgrading to NJ3?
Note: The phone runs fine when I boot into Philz and so it cannot be a bad battery?
Installing an ND8 Stock ROM on NJ2 disables Wifi. So I managed to install the Stock+NJ2+Deodex.zip and get the phone running just as long as it is plugged in.
When I unplug to run on battery, the phone turns off. When I try to turn it on, it gets to the Sprint Logo and then turns off.
I can boot into Philz recovery mode on battery and it works fine in recovery mode without turning off.
Does anyone have any suggestions as to what could be wrong?
[Solved] New Battery
Thanks for all the help.
The Sprint store tested the battery and it failed. Installed new battery and phone is now working again. What's the chance the battery gave out at the same time I flashed a ROM?
I'm not sure how else to describe these two problems I have.
Just for reference, I am using Cyanide L RC 7.1 from here: http://forum.xda-developers.com/galaxy-s3-att/development/rom-cyanide-l-v1-android-5-0-2-t2980174,
and I am using TWRP 2.8.5.0 for d2att. I have a i747M on Rogers.
Problem #1: boot loop only when plugged into AC charging
In the past week, I found that my phone gets stuck in a boot loop only when the phone is plugged into the AC charger. It will boot up, show the Samsung logo, then the Cyanogenmod logo with Cid, then show the Cyanide L boot animation. Once the animation is over, the phone just reboots. This happens endlessly (I didn't let it go on for more than 20 minutes, I didn't have time to wait). However, if I let the phone boot while it's not plugged in, then it boots up just fine. It also boots up just fine if I am plugged in via USB as a data connection to a computer. This only happens when I am plugged in via AC.
I have tried different combinations of USB cable and USB AC adapters. Doesn't seem to make a difference. I thought maybe it's a battery thing and borrowed a colleague's battery (also i747M), no dice.
Thoughts on what's causing it to boot loop like this?
Problem #2: Cannot wipe Data in TWRP
I discovered this problem when I was trying to update to the latest version of Cyanide L RC 8. I booted into recovery (TWRP 2.8.5.0) and proceeded to dirty flash the ROM. First boot had terrible com.android.phone FCs every 5 seconds. So I booted back into recovery a couple more times to reflash, same problem. I decided to do a clean flash and do a factory wipe. That's when the problem began. Once it reads "wiping Data without erasing /data/media" (or words to that effect) TWRP would freeze (the animated progress bar at hte bottom stops moving) and the phone would just reboot. The phone then gets stuck in an endless boot loop. I tried this numerous times, same problem. Couldn't restore a NANdroid either because it wipes Data before restoring.
I had to boot up into Download mode to use Odin to flash a custom ROM back and work my way back to a NANdroid I had. Took me the better part of 2 days without a working phone to get back to my latest NANdroid backup.
Any ideas what causes this freeze + crash in TWRP? I have reflashed TWRP, but I'm too afraid to test it out, only to lose another 2 days like that.
Thanks
Maybe you'll have better luck with Philz Touch recovery for the d2lte?
No luck with Philz Touch recovery. Tried that one, and also the latest TWRP. Seems to be the exact same behaviour with trying to wipe the Data partition.
I'm currently half way through using Odin to flash a stock TW 4.3 ROM to the phone. Hoping that this might solve my problems - perhaps something went awry during a recent ROM flashing, and I'm hoping that using Odin to nuke and pave my phone will fix it.
Fingers crossed...

If Odin doesn't get it try a wipe in the stock Samsung recovery.
What bootloader is on your phone? Hopefully, it is 4.3 or newer and you are using the stock ROM from sammobile.com.

I'm on NF2, so definitely not an issue with the bootloops and bricking that might happen by being on 4.2 or earlier.
Flashing with Odin worked perfectly, and yes I used a ROM from sammobile.com. After that, I flashed SuperSU and TWRP 2.8.6.0 through Odin as well, before downloading another ROM to test wiping, flashing, more wiping, and more flashing. So far no crashes in TWRP when wiping data.
I haven't been able to re-produce the boot loop when plugged into AC, it's only been a day, but we'll see if that rears its head again.
Well, it was a good 2 weeks, but now I'm back to having the same issues. This time I'm on a different ROM, but the two issues are the same.
I'm currently on S3Rx, 4.4 Touchwiz.
If plugged into AC (wall adapter), I get bootloops. If plugged into USB into a computer, it's fine.
Going into TWRP and doing anything with the /data partition causes the device to freeze up and then restart itself.
Is it possible that my storage hardware (the memory itself) might be failing?

The problem 1: you mentioned that the you are suffering with the problem of rebooting in the loop that occurs only when you use the AC wall outlet for charging. You must see in its rectifying circuitry detail. The problem may be there.
I eventually found a solution, though I don't know if it was a solution to the root problem.
My problem was that I was getting bootloops when plugged into AC charger. My solution, how ever random it seems, was simply to flash back to stock (via ODIN) to 4.4.2. Since then, my Problem 1 and Problem 2 were solved. This completely wiped everything on my phone (luckily I did a complete backup to my computer), but it also solved both of my problems.
It seemed the problem #1 was not caused by a bad charger or cable, as one might have thought.
I did a search and maybe not correctly but I did not find my particular problem.
So I have stock root66 rom flashed with odin 3.11 on my phone goes into boot loop.
I flashed twrp 3.1.1-0 with odin and I can go into recovery but as soon as I select any rom (OCT-N-WEEKLY-20170811-1427-d2tmo) it starts to do something and just reboots the phone and back into the boot loop. I reboots to fast for me to even figure out what it says on the phone.
Has anyone else experienced this? Battery is charged to 80%+
edit: tried CWM same symptoms reboots right away. Only thing I can flash with is odin otherwise with any recovery reboots right away. I was able to flash a modem with twrp and that works but no roms work.
update 2: I finally was able to get root66 installed. Gets to the set up part. Once I finish the setup the phone turned off on its own. It never turns on on its own so leads me to believe the power button isnot stuck but why does it turn off on its own? I turned back on and goes into bootloop.
The power button may be stuck in the "pressed" position.
Have you tried TWRP 2.87? You're sure you are flashing the correct TWRP version for the phone?

Thanks for the reply. I have tried 6.0.1.2_CWM_Touch-recovery-image & twrp-3.0.2-0-d2tmo.img but not 2.87.
However, as I stated above I was able to flash a modem but just not flash any roms which is weird.
If the power button pressed and the phone reboots when i pull the battery and put back in wouldn't the phone turn back on? I'm just finding it odd the phone keeps rebooting but when I pull the battery and put back in it doesnt turn on automatically.
update: So 2.8.6 twrp worked which is odd installing as we speak phone has not rebooted yet so lets see how it does once rom is flashed. I did odin root66 and after that installed it kept rebooting so fingers crossed this works. Using OCT-N-WEEKLY-20170811-1427-d2tmo hopefully this works
so after the flash seems to just back to the bootloop. I'm still not convinced my power button is stuck since it doesnt auto turn on and during the whole process of flashing it didnt reboot on its own only after the flash. Any ideas?
Literally gets to the samsung galaxy siii logo and reboots right away.
Try flashing the latest stock ROM, not a rooted stock ROM.

same bootloop. Gets to the tmobile animation and then reboots.
It's possible that the memory chip is damaged. You could take it to a repair shop and have it flashed via jtag.
