[Q] Note II: No more Root, Recovery & USB

Hello Gurus
I rooted my Note II N7100 way back and I have been using it happily since a few months, flashing roms etc etc. Here is the situation:
- I wanted to flash a new rom (dn3 v5) yesterday and I could not go in recovery mode and do the magic
- I have no more Root access, Recovery mode is looping & USB is not recognize, so I am stuck to flash it even using ODIN but the Note II boots on MIUI
Quick view:
ROM: MIUI v5 build 4.4.11
Bricked: Nope, I can boot and start on MIUI v5
What did I do before buggering you:
. spent hours goggling for a solution
. tried 4 different cables
. i tried to fixed the USB, so to use ODIN to flash the Note II. no success (developer options)
. did *#7284# on the dial pad to force USB mode to PDA is not supported by MIUI
. try with KIES, without KIES but the Note II is not recognize through USB - USB charging works
. tried on 2 different wintel 64 bits Win 7 boxes
. i lost root permission and recovery is launching me in loops
. Please remember before sending me post that I had a working system, rooted, with recovery mode enable for months.
Since the MIUI flash, I am stuck and don't know what to do next. I want to flash to another ROM and get away from MIUI but without recovery mode and no possibility to re map the boot loader with ODIN (Note II not seen by USB, but charges well) I really need your help for the next steps.
Let me know if you have seen similar issue and how to fix it?
Thanks
Benoit

No upgrade item to fix
In lg mobile support tool when i try to upgrade recovery it says no upgrade item to fix, help me guys i cant fix my phone yet:crying:

If you're still stock at the cwm loop, try flashing cwm again with a cwm.zip file. That works for me every time when I get stock in the recovery loop.
Edit: Besides flashing the recovery zip file, you also need to flash your ROM and gapp from within the new recovery you just flashed.

Click to expand...
Click to collapse
That is correct, get an ADB working folder in your computer (or download it from Google) and push a ROM with it, search for the commands on how to push a ROM through ADB, I'm not at home or else I'll point it to you step by step, try it on yourself and let me know if you need additional help.

Working now (Fixed)
Fixed it by flashing KDZ

[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,.
