How to install a recovery? - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi
I have a non rooted Note 4 N901F, L.5.1.1.
I didn't plan to root it for now, that is, unless I have to.
What I mean is I would like to have a recovery, like TWRP, so I can do full backups, wipe caches, and so.
How do I install a recovery? Do I need to root first?

Yes you need to root if you want twrp, there are other ways to backup your phone mate

Actually, you can flash the recovery before rooting. The method I use to root my C variant, is that I flash the TWRP through odin, then flash a custom kernel to root. So, you can say I flash TWRP recovery before rooting...

Root won't work

I just came from a custom ROM back to stock rom and wanted to root again. I flashed CWM recovery with ODIN en then flashed CWM-SuperSU-v.0.99.zip
When I opened the SuperSU app and clicked on update, it said installation failed. I went to the play store to update. Now it says I'm not even rooted . What am I doing wrong here?

Can I just flash over the current CWM recovery?

No, you were just installing supersu app (you don't need cwm recovery to do that), but not making root. Supersu is just a tool for root management. Flash cfautoroot with odin and then go to gplay and download supersu.

I flashed SuperSU (so including the binary, not just the app) in CWM recovery. How is that not making root? It should work that way, just apparently not for me.
so I already have CWM recovery, and the CF-auto-root brings the stock recovery. My question was whether I can just flash over it or not
edit: I just flashed over it, and works now

Supersu is just an app to manage root accesses, and binaries can be installed directly oppening supersu after install it from google play or from a zip using cwm (what you did), but first you need to make root. I am 99% sure that cfautoroot backups the actual recovery to restore again after root; if dont you can flash again the cwm after cfauto and you shouldn't lose root.

Stock rom + twrp

There are plenty of threads to answer your vague question.... But you have to be completely stock first.
So to be more specific, would I have to flash a stock recover, lose root and upgrade. Then root and flash twrp again?

That's right.
How about just flashing the OTA zip file in TWRP? That way you wouldn't lose data, right?
Could I upgrade to the latest twrp and is there a zip to flash?

Assuming you are on Android 5 (Lollipop) then things have changed and you need to use fastboot from a PC to install TWRP 2.8.1.0
That worked for me as I just upgraded my Nexus 5 with my Nexus 10 next on the list. Of note is that you need to root your device BEFORE installing TWRP due to some Android 5 specific changes. Chainfire's root fixes that issue with custom recoveries.
For example on my linux PC:
fastboot flash recovery openrecovery-twrp-2.8.1.0-xxxxxxx.img
All I did is flash the original 5.0 Lollipop release, then fastboot flashed TWRP and CFAR to get back root and done. Running the stock rom with TWRP and Root with no problems. I actually find this setup to run smother than the few ROMs that were created with options in them.

Lost root after install CM12.1 Temasek

Hi Guys
I just installed the CM12.1 Temasek, but when I check if my phone has root with the root checker leaves me no. Reviewing Internet tells me that in the options menu of programmer should I look for root access but that option dont appears to me, that you should do? or I can fix thi? i realize the update of SuperSU from TWRP and still does not work

Come on seriously. You flash a rom without checking the first post or at least read install instructions.
Warning: spoon feeding incoming:
To gain root access flash supersu file in recovery. Even linked to that file. Twrp doesn't magically root your device without having a file to flash. It's just a false reminder when it sees you have no root access.
Temasek removed the supersu from the rom as you have to do it yourself when you clean install. Get supersu survival after first install so you don't lose it on dirty flashes. Please don't ask how to do that. Just go to supersu settings and look.
Thank you

Chainfire update 2.46

What did you update? In other words, what were you on before this?
I always use this one http://download.chainfire.eu/743/SuperSU/BETA-SuperSU-v2.52.zip
Hey,
I too got my root access removed when installed CM ROM but the best way I did to recover my root is using ODIN and CF-AUTORoot files available on internet .
Just go and flash that .tar file and you'll get back your root access
IMO Odin should always be the last step. Flash SuperSU 2.52 from TWRP 2.8.7.0. It will fix whatever causes root to fail automatically

You are probably using older supersu and Twrp files, use the latest ones.
EDIT: Just follow what emuandco said in his last post, should solve the problem right away.

How do i reroot without bootlooping?

I'm a veteran at rooting android phones, but this is the first phone where TouchWiz roms won't boot after installing SuperSu. How do I root my stock rom(my phone has twrp installed), or install a custom TouchWiz rom(that automatically installs SuperSu) without bootlooping?

Flashing SuperSU from TWRP should work, is that where it is bootlooping?
Make sure to say NO if TWRP asks if you want it to root the phone for you after flashing SuperSU or that will cause problems, you only need flash SuperSU, and then refuse the next request if asked
There is also CF Auto Root, this is for flashing with ODIN

[Q] A2017G twrp root and a few questions

Well, I need root, I cannot live without backups and android without root and backups are incompatible really... thats what I dont like from android, so, my questions are.
The main question is, can I flash twrp without unlock bootloader to backup data? cause here first will flash, then unlock...
http://www.droidviews.com/unlock-bootloader-install-twrp-and-root-zte-axon-7-a2017g/
so I can flash twrp, backup, then downgrade, unlock bootloader, upgrade, reflash twrp, and restore data?...
Its possible?
thanks so much
As far as I understand:
You do not need to unlock bootloader if you stay with stock ROM (no custom ROM).
The signed TWRP (from tenfar) can be flashed using axon7tool without bootloader unlocked, and root (currently SuperSU 2.79) to be flashed immediately after (since you swipe to allow system modifications).
Then you must upgrade immediately TWRP (from inside TWRP using latest TWRP .img file https://twrp.me/devices/zteaxon7.html), otherwise the signed TWRP has fatal bugs and cannot be used to backup and restore.
I don't think that will work...
Use the stock backup app.
