Hi all,
I have a UK N910F 32GB Snapdragon Note 4, with a custom Lollipop rom that I've been using with no problems for a few months (http://forum.xda-developers.com/note-4/snapdragon-dev/rom-bob4-devbase-multi-csc-safe-bloat-t3033881). Yesterday the weirdness began - my Note 4 froze randomly in normal use and rebooted. It was then fine for around 5 hours, then froze again, and when it restarted it would continue to freeze on start-up. At that stage I could still boot into recovery (Clockwork Manager custom recovery), so I tried clearing cache and dalvik, which changed nothing. But now I am unable to do even that - it just gets stuck in bootloop and won't even go into recovery.
When I turn it on, it will stay on the Samsung splashscreen for 10 seconds, then reboot and vibrate twice, then go back onto splashscreen, reboots, etc. I need to remove the battery to stop this. The only thing I am able to do is boot into download mode, where the phone works with Odin fine, and I am able to flash successfully with Odin.
So far I have tried reflashing a stock UK 5.0.1 ROM - it initially gave me the ext4 error but I then got the N910F pit file and repartitioned - Odin flashing completed fine, then still got stuck on splashscreen with "Recovery booting...."). I have also tried to flash CWM and TWRP, which both flash fine, but then the phone still won't boot into recovery - I get:
#1 Battery in
#2 power on
#3 vibrate
#4 screen on RECOVERY BOOTING
Recovery is NOT SEANDROID ENFORCING
Set Warranty Bit : recovery
and doesn't boot into recovery. I'm pretty sure I'm using the correct TWRP and CWM versions.
I've spent all day trawling XDA and the wider web with no luck. Does anyone have any ideas on how to fix this? I'm hoping it is a softbrick but cannot work out how to get it back. I don't care about losing any data at this stage, just keen to bring my Note 4 back to life!
TL;DR: phone will stay on bootloop when powered on - not caused by failed software install, just started happening randomly. Cannot boot into recovery. Download mode works and can flash with Odin, but all attempted flashes so far haven't helped even when Odin succeeds in flashing.

Have you tried flashing your variants cf-root file with auto reboot unchecked, let it Pass, remove USB abd battery, wait 30 seconds and reboot? Sounds weird.. i know, but for a while that put many users on 5.0.1 softbricks back to their previous working ROM.
I've just done that, it flashed successfully, I took battery and cable out and then rebooted after 30 seconds - it is now booting onto Samsung bootscreen, says:
RECOVERY BOOTING
Recovery is NOT SEANDROID ENFORCING
Set Warranty Bit : recovery
Then reboots itself, same thing happens, reboots itself - back to a bootloop, but with the above written.
What's the fix for the above? Does it mean the recovery installed is wrong for the Android Rom version I have?
Thanks for your help so far, much appreciated.

If you can still boot into the download mode and want to boot into the system as normal, using Samsung's Smart Switch tool will work. Search Google for "Samsung Smart Switch" no quotes, install the program then after finished installing, in the application, click MORE at the Smart Switch window, then click Emergency software recovery and initialization, then follow on-screen steps.

Just tried that, same issue. When it boots after installation, it says "Recovery booting..." in top left corner, then goes into bootloop. Thanks for the tip though.
Any other ideas out on the grapevine? Or is it time for a return?
I'm having the same issue. Tried stock ANK4, BOB4 and BOC3. Only bootloops and can't reach recovery mode.
Than I tried TWRP 2.8.7.0 and "philz_touch_6.59.0-trlte" but they don't work either.
Don't know what to do now. Never had this issue before on any Samsung device
EDIT: Tried Samsung Smart Switch and it dowloaded PDA: OC3 / CSC: OB6 / PHONE: OC3 (DTM). But my Note bootloops furthermore
Saw 2 other guys with the same Problem and no solution here.
And I found this. This could be the same issue we are facing:

Hope there is a dev that can make this for our 910F
Hi all
This is now also happening to me...
Have Odind back to stock and it works for about 4 hours,
Then issue starts...
Reboots randomly
Then reboots to blank screen... No recovery
Again uk note 4. 910f
I flashed some 5.1.1 port yesterday, absolutely hated it, so went back to Arya. Now the problem is Arya was flashed successfully, but after hitting Reboot the device after flashing the ROM the device went to a reboot loop, (means it kept rebooting by itself, on a loop), and then I did the battery pull, and then the ROM finalising process was completed. I thought everything was all right, but just few minutes ago when I was rebooting the phone it went to the same reboot loop again, and now the battery pull doesn't work, it still going on reboot loop. It won't even go to recovery, I flashed the TWRP via Odin, but still. It does go to Download mode however. What is causing this problem? I tried to flash the Arya bootloader too, flash was successful, but nothing changed. Kindly help me out here, I have to have a working phone in less than an hour and I don't have any stock ROM I can flash via Odin and no time either.
Thanks in advance.
Heya
I followed a guide to download odin and CF auto Root-k3g-k3gxx-smg900h. I installed odin, booted into download and loaded the cf autoroot.
It takes a while before going to blue "RESET" and then my phone keeps showing the samsung logo.
After 2min Odin shows a green "PASS".
However I'm now stuck with a phone that won't boot and keeps showing the samsung logo.
I have tried the advice given in http://forum.xda-developers.com/showthread.php?t=2725939
Any advice would be appreciated.
After flashing with Odin did your recovery boot and do its thing, or did your phone reboot and just hanged on the Samsung screen? If the latter occurred, try repeat the entire Odin process again.
Heya.
I repeated the process, but while it says "Blue Reset" it's still sits at the samsung logo. The only way to then reboot is to take the battery out and put it back in. Then when I press vol up+pwr+home; nothing happens except the logo. No recovery mode.
The only thing that I seem to have access to is the Downloading.

Flash stock ROM again with ODIN
Don't use CF AR to root again, some phones just brick like that
Flash TWRP recovery, then SuperSU from TWRP instead
Hi, I am a noob. My Samsung S5 got stuck in a boot loop at the logo page. I flashed the firmware (G900TUVS1GPG2_G900TTMB1GPG2_G900TUVS1GPG2_HOME.tar.md5 - 6.0.1), and the problem was fixed. Then, when my battery was about to die, I turned it off and switched the battery, and it restarted in the soft brick boot loop again. I am unable to get to recovery mode unless it is charging. I tried wiping the data and cache partition, but that doesn't work. So I reflashed the firmware again, first in Odin 3.09, then in 3.11.1. It always passes in Odin, but when the phone starts to reload and load the firmware, it stops in the middle, says "erasing", and then goes back to the boot loop. Any ideas? Thanks!
For some context, I had successfully rooted my S8 with Magisk using TWRP just a few months ago before unrooting. I've decided I want to root my phone again and I went through the same procedure as before but I can't get into recovery mode now for some reason. The phone just auto reboots into the "Samsung Galaxy S8+" splash screen and gets stuck there until I decide to boot into download mode no matter how early I push the buttons to get into recovery mode. I've already flashed my firmware and tried again like 15 times already, so I have nothing to lose. Can someone help me out? Thanks!
