[Q] Stuck At Boot Animation From Lollipop Downgrade

Ok so I'd like to put AllianceROM on my international version SM-G900F H3G UK model.
To do so, my plan is to downgrade lollipop to 4.4.2 stock, root with TowelRoot, then install the ROM through Mobile Odin Pro (to preserve the KNOX counter). I've just tried to flash 4.4.2 onto the phone, but I cannot get it to start at all after it's flashed. The phone just hangs on the Three (H3G) boot animation.
I'm hoping that I've just got confused with the Sammobile site and that I've just flashed the wrong 4.4.2 firmware (so far tried flashing ANG2 and ANE2). Something I should have checked earlier but I just thought they were updated versions of the same ROM).
If I can't successfully boot into 4.4.2, I'd like to try flashing lollipop to retrieve some files I forgot to backup (another silly mistake). I'm not sure whether I can take files off it through the ADB sideload or whatever but if I have to lose all my data then I'm not too bothered.
What's the best way to go about my situation?
Any help would be greatly appreciated.

Right, thanks man. After flashing lollipop, I can now boot up and back up stuff. I'll flash 4.2.2 again and factory reset.

Stock ROM Backup

Hi,
I have rooted and installed TWRP on my 910F Note4 as I was fed up waiting on the lollipop update rolling out. I am currently on 4.4.4 and have made a full backup using TWRP of the stock rom.
My intention was flashing the Cyanogen ROM and using that, but i now see on sammobile there is a stock 5.01 rom available. I have a few questions about this.
1. If I flash to Cyanogen can I still revert back to the stock rom 4.4.4 I have made a backup with? I read somewhere there might be problems as I was on KitKat then moved to lollipop(Cyanogen).
2. Can I flash the stock lollipop rom from within TWRP? Or do you have to do this via ODIN?
3. If I flash the Lollipop stock ROM with Odin I assume I will lose root and TWRP? So this would have to done again?
Guess I am asking what is the best way to proceed?
Thanks again
Paul

hi Paul,
1. i beleve to flash CM from kitkat you will need to install the lollipop bootloader first.
2. You have to flash the stock rom via Odin, you will keep all apps settings and files but you will lose root (you u can re root in 3 minutes)
Best thing you could do is flash the stock rom first with odin, see how that feels (IMO its good been using it for months now) and then root it and back it up and flash CM12 (you dont have to flash any boatloader at this point)

Ok tried to flash Stock O2 UK lollipop ROM via ODIN and got error message on screen. MD5 too big or something. Had to pull battery on phone. Had to then reflash TWRP. Got back into TWRP and tried to do a recovery of the backup I took but phone is stuck at Galaxy note 4 screen. It then shuts down and restarts and gets to the same screen again.
Do I try a different ROM? What can I do?
Thanks
Paul

I got it working by flashing the German non branded ROM... Got the error message again but then used a "All samsung recovery.tar" as stated on another post in here and it booted fine eventually... Now on Lollipop. Now time to flash with TWRP.... Again!!!

Please, i need help !
I need help, urgently !
My Note 4 SM-N910C does not work. I can enter the Recovery and the Download Mode. When attempting to install a Custom ROM gives me an error that says I have no data. In the internal memory I have 0mb.
I tried using odin, but I can not .. Salta error.
Someone who can make a backup of your phone (which is factory), leave me a link to download it? So I install the TWRP. Please.
They have another solution?
Thank you.:good:

[Q] Bootloop

Before this I had a f2fs android 5.0 ROM.Today I tried to flash a 4.4.4 ROM((f2fs too,of course),updated to the latest recovery version,wiped everything I could(yes,I changed back to f2fs),but I got stuck in a bootloop.Tried with another ROM,same result.What should I do? Does it have something to do with the fact that I try to flash a kitkat rom after a lolipop one?

[SOLVED]Bootloop followed by blue screen when installing any custom rom

I rooted my SM-G7102 using KingoRoot App for Windows.
Later I installed Twrp recovery using Odin 3.10.7 :http://forum.xda-developers.com/galaxy-grand-2/orig-development/twrp-unofficial-twrp-recovery-t2798433
Booted into recovery, did a factory reset and tried installing Resurrection Remix: http://forum.xda-developers.com/galaxy-grand-2/orig-development/rom-resurrection-remix-m-v5-6-7-t3360391
It installed successfully I latter install 6.0 micro gapps as advised on the ROM's Page and rebooted however it just showed me Sammy BootLogo and then a blue screen and then restarted again
I later did a complete format including /data and also tried installing CM13 unofficial: http://forum.xda-developers.com/galaxy-grand-2/orig-development/cm-13-0-ms013g-cyanogenmod-13-grand-2-t3299635
however same results.
Another alter I tried was installing both ROMs mentioned above without GAPPS however it didn't work too!
Would love to recieve some help, Thanks.
[EDIT]
p.s: I was using Samsung's Stock Andorid v4.3 firmware before flashing.
Also here is my recovery log: https://gist.githubusercontent.com/ArchKudo/ab4738a2482121fde280643fc86b5ab6/raw/0cae8a800552fc331d841bd1a6798c9a41e524ec/recovery.log

Thanks for the reply!
Should I use the same TWRP recovery as mentioned before?
Also is 4.3 known to cause bootloops or is there some guesswork involved?
