*Please Help* -- Note 2 boot loop after factory reset.

Hey guys,
I know there are a few threads like this, but its probably easier if i explain what I done and how it happened sort of thing.
Basically I had a phone upgrade from my Note 2 and got a Samsung Galaxy S5... So now I want to sell my Note 2 which was ROOTED, but still had the Stock ROM installed as I just wanted it rooted for apps like Greenify, etc.
Anyway, so it was a fresh phone I did a Factory Wipe/Clean from the recovery (its the purple gradient one, might be TWRP) and then I wiped the cache.
all was fine, but i noticed after the phone reset there was still some of my apps and documents on the phone, so I did a Factory Reset through the phone software itself ("Backup and Reset") in the settings menu.
Anyway, now it is stuck in a bootloop and I have no clue what to do, please help as it is money down the drain otherwise.
Many Thanks in advance.

[Q] Device powercycles when trying to make or recieve phone calls

In the past few days after flashing alliance v2 i noticed that my phone would freeze then power cycle when I attempted to make or receive a call. Everything else works, I tried a different rom and still having the same issue. Any ideas?

HELP!!! Need a PIT file for N4
Odd problems that carry past factory reset and ROM flashes require a better flush. And clean install.

So I had already started when I saw that, though the second post on that thread is a little confusing. However I had already odin back, booted up, but didn't wipe it, so instead I hooked it up to samsung kies, and did a full restore from kies. Made a test call, still froze, and crashed. So re rooted and put twrp then did an excessive number of advanced wipes. I even used the repair option to repair system then data. Just flashed vision and waiting on it too boot to see. Should I move further questions to that thread?

I'd suggest keeping your posts on this thread. Just referred to that to save time.
Try the steps. Ask if not clear. If it sounds too extreme, start with the factory reset, Odin and factory reset again before flashing a deodexed ROM like Alliance. Update with results.

Ii did as follows and tried several other ways, same results on factory image, unless I have a bad image, I pulled it off of one of the forums here

Are you powering down prior to Odin of stock tar? Did you use your PC to download the tar? Have you tried doing this without the sdcard? The full wipes are important.
Try the NIE stock tar.

Ive wiped everything and formatted data repeatedly......I had a nand backup i forgot about, I'm going to restore that and see. I haven't tried flashing anything without the sd card from recovery, I have removed my SD card for the moment. It does seem like this is the issue, something with the partition. It's of course possible I didn't follow directions properly, though I feel I have. I'll also try NIE if need be. It's very bizzare issue. everything else works fine.
Update: Flashed NK2 stock tar, tried to make a call, same thing, phone freezes and powercycles.
Update 2: I even tried a different dialer, same results. Could a hardware issue cause this?

My suggestion is to try the factory reset, power down, Odin and Dial*##72786# to reprovision the phone; data profile update and try again.
Still fails? Could be hardware failure.
Anyone else?

Ive done all of this, even the 72786, tried wifi calling too just to be sure. maybe something with the antennai

Outside of a good suggestion, I'd stay with stock, call Sprint support. If not resolved there, setup a tech appointment.

Note 4 bootloop... hardware failure?

Hi,
I plugged my note 4 into the OEM charger and all of a sudden it just goes into a bootloop continuously.
Occasionally it will reach the home screen and reboot again, but more often than not.. it reboot before the Sprint logo comes up.
Was fine before i plugged it in and was trouble free prior to that.
My phone is stock, not rooted.
The fact that it will reboot even at the Note 4 welcome sign is leading me to believe this could be a hardware issue...
Any ideas?
Anybody had the same situation and had luck troubleshooting or fixing this?
Any and all help i much appreciated...
Regards,
asmd.

Can you boot into recovery?
First thing I'd try is to pull battery, boot into stock recovery and wipe cache and try to boot.
If not booting, try wiping cache and dalvik.
You have the option to just take it in for evaluation but you should determine if you have reactivation lock enabled before doing anything else.
Still not booting? Factory reset. But if you have reactivation lock enabled that is not a good idea. It would be better if one of the two above booted the phone.
If reactivation lock is enabled, you need to install the same update the phone is on to prevent factory reset protection from activating. Don't factory reset yet; Odin or taking in for service may be your only option. If it boots, you should be able to open with same unlock method as before.
If you have reactivation lock disabled, you're free to try factory reset or update to latest through KIES. I've heard Samsung Switch may work too. You could also factory reset and update or emergency recover with one of those.
If still not booting, if it just updated, I'd mention that and not the charger you mentioned. It could be corrupt memory due to battery failing or bad update. The eMMC may be failing too.

Thanks for the reply...
Ive been messing with it all morning... and if i leave it a lone and it cools, it will last a little longer than when it becomes warm, rebooting quicker and quicker.
i managed to get into recover and did a factory reset and cleared cache.
it has made no difference.
The longest time its gone before rebooting is the lock screen.... and the it reboots again.
as it warms, it eventually wont even get past the Note 4 welcome screen before rebooting.. and then finally freezing and will require a battery pull.
Makes no difference if its on charge or off.
i have a sinking feeling about this.....

Could be terminal but you haven't tried to flash firmware on partitions with Smart Switch, KIES or Odin yet. Right? You can check the phone status while in download mode to verify reactivation lock is disabled.
Try one of those on PC or take it to Sprint to have it flashed again.
If you purchased at Best Buy and they have a Samsung Experience kiosk, they can do that too. Dunno, maybe it doesn't matter if you purchased there or not but they've flashed my phone a couple of times.
I've tried to guide you down the path of least effort to restore your, if possible. There's still some hope of recovery.
Edit: Your battery could be suspect. Let it cool and plug in to make sure it's at least 60% or higher. If the battery is near a year old, I'd suggest fully charging but get a replacement if you frequently discharge it to 15% or lower. Especially if you use fast charging.
But you've most likely discharged it with all that reboot activity and heating up. Kudos to you if you're managing all that and keep a healthy battery. Otherwise, the battery may be contributing to or causing your issues.

thank you for the help..
reactivation lock is off.
i can't get it to reliably not reboot anywhere in any screen.. only screen that will stay on for any period of time is recovery... but the phone stays cool.
Its not the battery, i have two, and both do the same thing.. the battery does not get warm, area that gets warm is neft to the battery below the sd card slot. (sd card removed).
Frequency of hang/reboot seems to be related to how warm that area gets.
The most i have managed to do is get into my phone past the lockscreen and it will shortly freeze and reboot as it warms up.. it will reboot at the note 4 welcome screen or sprint logo... and repeat... eventually to hang.
Both batteries are charged fully using the external charger. (samsung oem)
Shame, not a scratch on her....
Oh well, on to Ebay for parts/AS IS and time to move on...

Even if doubtful, I'd still take it back to Sprint or place of purchase.
The Note 4 has a bit of history with eMMC failure. It's even happened with updates and Samsung and Sprint is apparently aware of it. A while back I saw that listed as an ongoing carryover of known issues that needed resolution.
I don't have true stats on exchanges but several users here have repeatedly gotten deals on replacement phones, paying a small percentage when they failed- similar to yours.
OTA updates have also been suspect to cause eMMC failure. But honestly, l don't know what causes this: bad hardware or updates? Maybe it's just bad hardware not taking updates well? Nonetheless, I don't know if I've just been lucky or my hardware is stable. Still going strong here with no hint of failure.

No promises. Couldn't hurt. If you don't like the answer you get from first Sprint store, try another.
I would mention that bit of history with the updates.

I have the exact same issue going on with my wives phone. Just started yesterday out of no where rebooting over and over. Never really getting past the Samsung splash screen. She got an update like a week ago, but other than downloading a new app several hours earlier nothing sticks out to why its happening. I was able to once get into safemode, but the phone rebooted a minute into it and typically doesn't even get to the sprint splash screen when I've tried to do it since. It's totally stock and has not been unlocked or rooted. I thought it could be the battery since so many of these boot issues on the Note4 deal with that when googling, but my battery from my working Note4 in her phone does the same thing and her battery in my phone works just fine. I can get into the recovery options menu (volume up + home + power) and I can get into the download area (volume down + home + power) for loading bootloaders and such for long periods of time with no issues. I've cleared the cache with no luck. Haven't tried factory reset yet because I want to try to recover the photos and stuff first. Searching for the issue on google I came across this software (android-recovery.net/android-recovery-mode.html#two) where I was able to use the download area and connect the phone with this app which used its own bootup and it was able to show me all the files on the phone for recovery so we could retrieve them. It wanted $50 to complete the process though and, knowing the advances that everyone here has made on their phones I decided to decline that and search these forums for a way to just access the file directory of my the phone and retrieve my wives stuff prior to factory resetting it. I believe something is wrong with the bootloader of the phone and that is why it cannot get to the android OS to start up, but I could be wrong. Reading various articles made me to believe that if I just were to unlock the phone for rooting that possibly that could fix this issue with the bootloader or at least be able to recover her photos and stuff. I do have insurance on the phone and could get it fixed or replaced, but that would be a $200 deductible I believe and first thing they're going to try is factory resetting the phone which will lose her data we're trying to save.
It almost seems as if I were to get TWRP installed that I'd be able to access the files without the need of loading any ROMs. But I'm not sure if that will work in my case or erase data when I do it. The threads I'm reading aren't clear on that part. I would really be grateful if anyone could help me out with figuring out the easiest way to recover her stuff or get it working. Its been a long time since I've unlocked any phones and they were all iPhones back in the day when they were only on AT&T and I had T-mobile and wanted to it work.

@dsm_gsx97
I would suggest you try Odin and install the same update, if possible. That may be the most likely to retain your data if it's not corrupted.
Unfortunately, I don't think TWRP recovery works for Note 4 to copy data to PC. But if you go with that, know that it will trip Knox and void factory warranty. But if that's not an issue, you could copy data from internal memory to extSdCard to salvage it if it's not corrupt or private.
I know KIES has an emergency firmware recovery mode that may offer to reprogram it. But you may lose your data. Not sure but I think your phone has to booted into system to backup with KIES or Smart Switch?
This thread has the recent available stock tars, Odin and general instructions to get you started.

Thank you very much for the quick response. I would rather not void my factory warranty in case I have to use the insurance to replace it so it sounds like TWRP is out which is why I didn't use it yet because I was worried about that. I did try KIES and it said that firmware upgrade and initialization would erase all data. So I ruled out using that too. I did notice while in the recovery menu of her phone that it says she's on N910PVPU1ANIE ...so I put my phone in recovery menu and I'm on N910PVPU4DPH4. Googling her version it looks like hers is very old and mine is fairly new which makes sense because I did the update a few days ago also. I wonder if hers is so old because that's what the other software program put it on to be able to bootload it to recover the files.
Anyways looking at your link I think I'll try oden with one of the more recent TARs after getting her stuff off with that program. Yes I'll just pay the $50 for peace of mind. I really appreciate your advice. Its not easy gathering all the answers without really being involved on this forum so thank you for that thread. None of the TARs listed is the update I have, but that shouldn't matter should it? As long as its a newer one than what it says she has?

Was it only the OTA update that updated that phone?
NIE is the original-initial release of the Note 4. If OTA tried to update it, it must have failed?
Nonetheless, you should know the history of that phone. I wouldn't install one of those recent updates until you've backed up your data. You may lose your data jumping to a much newer update.
The phone doesn't boot at all? If it does boot, you could run Phone Info for Samsung from Google Play to see what the partitions are actually at. That would help to recover that data if possible to do so. But also KIES could backup data if it boots.
The NIE stock tar is in post #2 of this thread.

If it boots after Odin, your data may be OK. If not, may be corrupted data or partition.

She's done plenty of updates over the last few years since we got the phoens. In fact she did that last update a few days before I did. That's why I was confused when I noticed what it said at the top of the bootloader screen for her update version. The phone does not boot at all. Only to the the Samsung splash screen and never gets to the sprint splash screen. It initially would get further, but now doesn't at all. I went ahead and paid for that software and have now backed up all her stuff. Was hoping to fix it without factory resetting the phone. At this point at least I have a backup, but ideally it would save her from losing all her texts and other crap.

In that case, try the most recent stock tar in the first thread you were about to try.
Something seems off but trying to flash the original stock tar would be problematic if it was updated beyond Android 5.0
If it doesn't boot, you'll most likely have to factory reset it.

Pixel xl phone app unresponsive 9.0

Hi, I'm aware that several people have issues with the new pie rom.
Unfortunately, I have a problem that I haven't seen before on the forum:
It takes like a full 5 sec to call somebody and the same to end it.
It's very frustrating because I never know how to react in this situation (did he heard? Etc...)
I don't want to factory reset and I got everything stock.
Anyone has an idea on how to fix this?
Can I wipe cache with the stock recovery? Maybe install an other phone app?
Thx

i am having issues in pie as well. i cant seem to transfer large files to the phone.doing so makes the phone restarts. i tried it 5 times or so. fhis update is not good

Only way to clear up issues is a clean factory image install if this was not done to begin with.

OK thanks...
Though I blindfully hope someone will be get some alternative has I don't want do execute such extreme solution

It's actually relatively painless. Apps restore automatically when you go through setup, calls and texts are restored, as well as system settings and WiFi networks. Takes me ~30 mins total, and maybe 5 of that is actually looking at the phone, the rest is letting it sync and restore backups automatically.

I was thinking about it doing a factory reset once the final came out but I've heard stories from fellow moviepass owners that are unable to use the app when switching phones. That would make a valid concern for factory resets as well. Not because of lag but I have noticed battery seems worse after the upgrade and wanted to factory reset to rule out. As I ran all the ota betas of pie a factory reset isn't a bad idea anyway.

Your device ID is tied to the app. When you factory reset and reinstall the app your device ID is reset. You can root using Magisk and then install Titanium Backup to backup the app and data, this will preserve the ID. i had to do this when switching ROMS.

How can I Factory Reset while rooted without bricking

So I stupidly tried to upgrade to the Pixel 4 Launcher before the official Dec update came and even after trying to uninstall/reinstall the .apk and downgrade etc, I still can't get the launcher to be remotely usable without the error popups if I have gestures on. So I am resorting to factory resetting and just starting from scratch.
I feel extremely dumb asking this as I've been rooting/customizing my phones since the G1, but about 6 months ago I had to send in a phone for RMA and when I factory reset it, wiped the OS and the bootloader was locked, so I am making sure I don't do that this time as I'm now out of warranty.
What is the process of factory resetting when I am rooted with Magisk and have the bootloader unlocked? I don't have a custom rom, just stock Android and I do not have TWRP installed. I feel like it's as simple as just going into Settings and hitting Factory Reset in Reset Options, but I can't remember if I did that or something else when I bricked the RMA phone and want to make sure.
Again, sorry for the completely stupid question, just trying to cover the bases. Thanks in advance!

It's like you said, go to settings and factory reset. Or, go to stock recovery and do it from there :good:
