Go to sammobile.com and download the latest firmware for your phone. Use Odin to flash it.
If you are rooted and have custom recovery like TWRP - do a nandroid first than once the stock has completed you can re-root, flash the custom recovery again and then restore system and data from the nandroid and you should be back to normal but with updated BL and modem.

To flash a flashable .zip file you need a Custom Recovery like TWRP. So,
1. Root your phone with IORoot25. - This will give you root.
2. Download and run AutoRec on your phone. - This will downgrade your bootloader to JB and install TWRP.
3. Boot into Recovery Mode (TWRP) and flash your modem.zip. - This will give you a new modem.
Remember to back up your modem before flashing a new one.
Thank you so much.

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

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:

TWRP doesn't touch the bootloader. /boot refers to the boot partition which includes the kernel and initial ramdisk. The bootloader is on a separate partition.
In addition, kitkat and lollipop bootloaders are similar enough that the TWRP and custom kernels work same on both.
Do keep in mind that if you flash stock ROM through Odin, it will replace your recovery with Samsung's stock, so you need to reflash TWRP.

Depends on what you mean.
If you are just talking about the bootloader, you can flash that and the radio through Odin separately.
If you are talking about the ROM, then typically you would flash stock through Odin.
If you are talking about custom ROMs, then you don't need to care about which bootloader you have.

How to revert back to the stock firmware?

Hi All,
A couple of days back, I installed custom ROM (Recreated Remix Leopard) successfully on Zenfone 5. I was on the stock lollipop 3.24.40.87 firmware before that. I rooted, unlocked Bootloader and installed TWRP recovery on the stock ROM and I also took a nandroid backup. After using the custom ROM, I decided to go back to the stock ROM. I used the nandroid backup for restoring and got the stock ROM. But, now I want to go back to the stock Kitkat ROM (as the lollipop sucks) and I also don't want the custom recovery or anything. In short, I want to revert my phone to the real factory condition.
I tried to go back to Kitkat by the ASUS official method. But that didn't work. Then I tried to re-lock the Bootloader with the tool from which I unlocked it. But when I did that, I got stuck on the USB logo screen. So, I unlocked it again with the same tool and the phone starts normally. So, how do I get back now?
What would happen if I flash the stock ROM via TWRP? Will it remove the custom recovery and lock the Bootloader?
I read a couple of articles, a few of them suggested to install the stock ROM with the official ASUS method (copy the files in internal storage and the phone will notify to install the update). The article even says that by this method any custom modifications (recovery, root, Bootloader) will be deleted. Is it true or will this work?
Thanks in advance!

Link rom WW 3.24.40.87 modded, flash via TWRP: drive.google.com/open?id=0B7Py5ad2aHwKMHRsZ1NJM0tfLTQ
If you flash this rom, it will not remove the custom recovery + lock the Bootloader
If you having a problem while flashing this rom, you need to flash stock recovery 2.22.40.54, after that you can sideload stock rom via ADB
Sorry for my bad english ^^

Hi, thank you for the reply
You said WW 3.24.40.87 modded, do you mean that this rom is not the official one? Does it improves the battery life and other bugs of the stock rom?
I really appreciate your help!
You cannot flash stock rom via TWRP!
This is modded rom, so you can flash it via TWRP easily....
It's Official rom from Asus, just modded to be able flash through TWRP

Thank you for the info
But the thing is that I am already on the stock 3.24.40.87 rom and I want to go back to Kitkat 2.22.40.54 because it has much more improved battery performance than the lollipop. Is there any modded version of the stock Kitkat rom too? Or how do I go back to it?

Downgrading from CM 14 Nougat to stock TW 5.0 lollipop???

Sorry if I'm posting in wrong section actually I'm a newbie
Hi all, I've updated my Note 3 SM-N900 to Cm 14 nougat 7.1.1 unofficial lonage os by ha_3g. Now i want to go back to my stock Twiz 5.0 lollipop, is it possible I've all my rom backedup by TWRP. Can i restore my backup without any problem?
Thanks in advance
nah,usually i just flash my firmware using odin without backup
Usually if you want to revert back to stock firmware, everything will be removed, including your custom recover(TWRP in this case), miscellaneous files and folders that were previously on your custom ROM. So, in summary, you won't be able to recover your backed up apps/data as TWRP will get wiped out as well, being replaced by the stock Samsung recovery.
Yep, wipe system, data, cache & dalvik then restore your backup.
Before updating I've backed up my stock Twiz rom via TWRP, now i just want to revert back to my Stock rom which was lollipop 5.0. I'm afraid bcz I've seen some where that we cannot install 5.0 (lower version) over 7.1 (greater) version it will brick the phone bcz of some bootloader issues, btw I've not messed up with bootloader, so plz advise me if it will be safe or not.
Lot of Thanks for the members of the forum who replied in no time & who r ready to help. Salute to all of u. you people r great
Only a stock firmware flashed with Odin can upgrade your bootloader.
And the latest official firmware for Note 3 is Lollipop 5.0.
So your bootloader still 5.0 even if you flashed a nougat rom.
Even more, custom roms don't touch bootloader or modem partitions, ever.
Go ahead
Hey bro. Just go to sammobile.com and download your rom and flash via Odin. Only Odin can downgrade your BL and Modem
Thanks alot for the clarification I'll go ahead now.
I can swap between 7.1 Nougat and 5.0 stock, with no issues, through my nandroids.
If you had a nandroid before, you shouldn't have any issue just using the TWRP function to restore your backup. It will be exactly as you had it before.
The only difference will be that you will still have TWRP installed, etc.
Anyways, you can swap back and forth as much as you like. You don't have to wipe anything, or use Odin, since you made a nandroid already.
Yes you can go back to lollipop . I have done that in my sm 900 exynos version. marshmallow and nougat drains battery
