So I bricked my N4 somehow (I don't know if it is soft or hardbricked).
I was running latest N5X AOSP 6.0 Lollipop and everything was fine, when i decided to try the AICP 0.1 experimental LP. I made a clean install but it the first boot ended in a black screen. Then i rebooted into recovery and made a factory reset and since then Im stuck in an infinite bootloop.
So here is what i tried so far:
Flashed newest Factory Image via Fastboot and ADB. Result: Bootloop
(Flashed with flash-all.bat and every img by myself, i even tried without flashing cache.img and userdata.img, but everytime i ended in a bootloop that goes longer than 30 minutes)
I tried several Toolkits but nothing helps everytime I reboot its a bootloop.
But somehow when i flash the N5X AOSP 6.0 and let it boot for some minutes and then just shut it down and boot again i can see its optimizing my apps but when it comes to start them i just stays there...
I also tried to format my /cache with TWRP into FAT and back to Ext4 (that was one solution i found) but that doesnt seem to work too..
I am very frustrated and hope someone can help me
Greetings.
I am sure there is an answer on XDA but an hour of Googling has got me stumped. Please point me to the right answer.
Starting point
Rooted N900T, stock rom, stock recovery.
What I did
Installed ROM Manager
Told ROM Manager to install the latest CWM for my phone. Completed with no errors.
Tried to boot into recovery with the standard "hold power, vol down, and home" but I could never get into recovery. It would look like it would start to boot into recovery then it would reset and boot into the regular ROM.
Then I told ROM Manager to reboot me into recovery.
Then it went badly... I am stuck in a boot loop that continuously shows going into recovery, then samsung logo, then repeat.
I have pulled the battery, tried to go into download mode, tried connecting USB, tried Odin.
What I want is a working phone. I would like to back up the stock rom and go to CM12 nightlies but for now I will just take a working phone.
Please help,
David
think I found the answer at http://forum.xda-developers.com/showthread.php?t=2666432
At least I got out of the loop, not fixed but progress.
That worked, the only other piece of info you might need if someone else has this problem is that there is no PDA button on the latest version Odin, it is called AP
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, I hope that someone can help me revive my S5. I was on resurrectionremix rom but decided to see what pure N5 rom was like. I asked up my rom then done the normal procedures & installed the N5 rom which booted up fine, after playing around with it for a Shor while I decided that I prefer resurrectionremix so I booted into twrp recovery, factory wiped as i have done many times in the past, when it had finished I rebooted but I stead of booting into life I was confronted with 'Downloading,... Do not turn off target' see attached picture & now I am unable to boot up. I have removed the battery and sim for 5 mins but nothing. If this has been posted before please could you direct me to it. Thankyou in advance
Did you restore your backup?
Flash TWRP again
Yes, tried flashing twrp recovery with Odin but still goes to the same. Trying to download the stock firmware from Samsonite but it keeps failing

Use samfirm tool
http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647
Just enter SM-G900F and BTU in the top left panels, and tick automatic for the rest
Then check the "Automatically decrypt" on the right, and hit download
When you flash TWRP with ODIN, flash TWRP 3.0.0.0, and uncheck "Auto reboot" in ODIN
Once it completes the flash, disconnect USB and pull the battery to power off, then replace battery and immediately boot into recovery with Volume Up & Home & Power
Thanks for your help, appreciated
So I was installing twrp and everything went right until it didnt boot to the recovery and from then it keeps booting to lg logo and bootloader warning forever.
I know I can install the stock rom with lg up by I cannot enter download mode since the phone isnt technically turned off. Does anyoene have a solution.
It's my main phone and I literally cannot afford a phone right now.
A way to turn it off would be the solution. Battery was around 70% so it will take a long time to actually have 0%.
Update: I got to the fasboot menu from where I can run fastboot reboot recovery after installing twrp again. Now I have some mounting issues and I cannot flash any zip without entering bootloop. Im trying to use the shut down menu of twrp to try to enter download mode.
2nd Update: solved using lg up with the latest android version.
