Potential downgrade issues ( from 5.1.1 to 4.4.2 )

Hello,
Since we are all still stuck with this partially functional root on our dearly beloved SM-N7505 on 5.1.1 , i started considering downgrading it to 4.4.2 ( last version i had root fully functional on ) .
I wanted to know if there are any risks I might come across during the process and what should I do before hand
P.S : One of my friend lost his IMEI due to the downgrade on a Galaxy S3 (which was a pain on the ass to fix)
Any info are welcome, i need to know as much as possible before i proceed
Many thanks

NO bro there will be no problem to downgrade, just download rom zip file from here - http://www.sammobile.com/firmwares/database/SM-N7505/ and follow the steps :-
1. Extract (unzip) the firmware file
2. Download Odin v3.10.7 (http://dl.sammobile.com/Odin3_v3.10.7.zip)
3. Extract Odin ZIP file
4. Open Odin v3.10.7
5. Reboot Phone in Download Mode (press and hold Home + Power + Volume Down buttons)
6. Connect phone and wait until you get a blue sign in Odin
7. Add the firmware file to AP / PDA
8. Make sure re-partition is NOT ticked
9. Click the start button, sit back and wait few minutes
congratulations you have downgraded your mobile!

no problem in downgrading from 5.1.1 to 4.4.2. but you should remember that after flashin 4.4.2, you may need to enter recovery, and wipe data + cache, or else you may face bootlogo stuck

GT N7100 no start error. No recovery. No Logo

Hello. I have been using Note 2 GT N7100 for over 3 years now. Have rooted the phone and was running a Crdroid custom ROM on it. It did not give me any problem. Nor did I update the ROM since it was running good.
Suddenly yesterday it got stuck on the Samsung logo. Tried restarting it, but it didn't move ahead of the logo.
Today, it shows a grey and white screen. Fully blurred and can't see the Samsung logo too.
Tried going into the recovery mode, but same grey screen appears.
If I take it in download mode, it goes there. But when I try to install any stock ROM, it doesn't work. It shows failed in Odin.
Please help what can be the possible problem?
If any more information is needed, I will provide it.
Any ROM to install or custom recovery?
Please guide what to do?
Also, I am sorry if there is already some post like this. Please let me know
Thanks in Advance!

Hey thanks for the quick reply. Will try and get back to you.

Need a valid link for Recovery Package
[I moved this post to this section that's more apropriate http://forum.xda-developers.com/showthread.php?t=2154890 ]
Hi guys,
Is there a link for the Recovery Package/ROM ? (the one above doens't work)
My phone is stuck on the boot logo and I need to fix it... (I'm a bit noobish..)
I've had already downloaded those files but i'm not sure that there are the correct files to use in the step 4 of this tutorial (Recovery Package/ROM).
- N7100XXUFND3_N7100OXAFND3_N7100XXUFND3_HOME.tar.md5
- N7100XXUFND3_N7100OXAFND3_XEF.zip
Thank you a lot !

Firstly , what have you done ? - to get in this position ? there are many threads on here to unbrick devices , reading is best especially if you know what you did to get in the state you are

Me too had a same problem. u would have tried to flash with wrong file. flash with correct firmware it will 100% ok

I had the same problem but this thread sorted it for me:

[install TWRP]How to unlock bootloader on Samsung Galaxy Note 4 / N910F / Marshmallow

Hello,
I'm trying to install TWRP recovery mode on my Samsung Galaxy note 4 ( version N910FFXXU1DPE3) running under android 6.0.1 Marshmallow
I have rooted my phone (installed the CF_Autoroot stuff with Odin) , but it doesn't seem to be enough, because when i install TWRP and try to boot in recovery mode, my phone show a message "unable to do normal boot" and switch in "download mode" and get stuck in it.
I Fixed it to work normal again, and try to find what i did wrong :
And It seems I missed to "unlock" my "bootloader".
I try to find on internet how to do it, but i can't find anything
Either the file links are missing,
Either it's only for Android 5
Either its for another version of Galaxy note, and not for mine : N910F
I can't find any good tutorial to do it, can you help me with this ?
Thank you !

I have the exact same problem, I know this thread is really old.
But I can't find anything about unlocking the bootloader for n910F, and as above - it's definately locked because I can't change the recovery,.
