Hello there!
I'm new to the Samsung's world so I have few questions I hope someone can answer.
1, I am a fan of stock kernel and I noticed TWRP has a recovery and there is a No root method mentioned using Odin.
https://twrp.me/devices/samsunggalaxys6edgeplus.html
So if I flash this recovery and flash the SU will the device boot? So do I need the custom kernel to get the phone booted with custom recovery?
2, I hear we will trip the Knox in the process of root. Do I lose Knox functionality? Since I use Knox for my company apps I would like to know if I would lose that functionality ?

Hi,
Tried to google it, but seems i just can find howtoos on installing custom recovery if i root the phone.
However before i root the phone (since its a work phone) i would like to make a nandroid backup of it just incase it needs service sometime in the future. And therefor have a NON rooted image of it.
So my question is: Is it possible to install a custom recovery to make a nandroid of the S5 without rooting it and voiding the warranty?

Second If I'm sure you will not void your warranty but MAYBE you will have in download mode Knox Flag 0x1 or something like this and Custom binary 1... BUT MAYBE I'M NOT COMPLETELY SURE
Install custom recovery, kernel, ROM etc. sure trip Knox to 0x1. Unfortnately reset doesn´t exist.
Only towelroot doesn´t trip knox.
Is it possible to undo towelroot again without a nandroid?

Hi,
When towelroot came out I installed it on my note 3 so I could get root without tripping knox. Last night I installed safestrap to get a custom rom without tripping knox, but when I installed alliance rom on rom slot 1 it somehow also installed the TWRP recovery and tripped knox. So now that my warranty is void anyway I was thinking about
installing another rom, just the normal way.
My question is if I should I unroot my phone first and root it the root de la vega method or can I just install whatever rom or recovery I want with my current settings/configuration? Also when I boot my phone into download mode I still get the custom OS warning, I don't know if that's a problem or should I press continue there?

Since you have tripped knox, no worry anymore on warranty. If you plan to flash new rom, you are always advised to have clean installation, meant to clean everything, else you will experience unnecessary problem. To backup your current setting, download titanium backup to make your apps and setting backup. You need to spend some time to familiarize with TB. It is very handy to help u restore previous rom settings and apps.
You do not need to unroot your current rom.

@Marcel94 :
I have never use safestrap anyway... so I have no idea how it works actually.
But... a clean installation will be good.
Grab latest firmware nd flash through odin, and go to recovery stock and do factory reset.
Then root with cf-autoroot, flash cwm/twrp.
Then flash ur rom.

Thanks for the advise guys! What do you mean with "go to recovery stock"? Will my recovery be stock again if I flash the latest firmware through odin? Nevermind, I already flashed the stock rom and got stock recovery, thanks!
Hey XDA,
I'm about to install TWRP via Mobile ODIN Pro (v4.20) and I have a few questions.
1.) It says it will trip KNOX, but when I installed SuperSU I have successfully disabled KNOX. Does this mean that even if I install TWRP recovery, KNOX still won't be tripped?
2.) Can someone point me to a link on how to install TWRP step by step via Mobile ODIN? (I found one that shows how to install FlipZ Custom CWM, but I'd like one for TWRP) I need the latest TWRP version link also.
2.5) Can the stock recovery make nandroids? I'd like to make a nandroid before flashing TWRP, but if I cant it's no big deal. (Again, just wondering, but I still want TWRP)
I just want to do this right so I can make a nandroid backup. I am already familiar with TWRP from my HTC Evo 4G LTE, so im not interested in CWM.
FYI: I am on the stock ND2 rom - G900P (Sprint) - KOT49H.G900PVPU1AND2 - (if that helps you)
Thanks in advance! - zmag
Ad 1. Custom recovery trip Knox to 0x1 = loose waranty for motherboard
Ad 2.5 No.. Only custom recovery

You have not successfully disabled Knox and as you already know, installing a custom recovery like TWRP will increment the Knox flag.
No, the stock recovery cannot make a full backup. That is one of the primary benefits of TWRP. Your best backup alternative given a stock recovery would be Titanium Pro, which isn't nearly as good as TWRP. After you install TWRP you can make a full backup.
The only obvious way to make something resembling a Nandroid without a custom recovery would be to use the dd command from the command line and back up each partition.
You were just telling me in another thread how you always do forum searches. It's not hard to find numerous Odin tutorials if you search.
.
just get img file of stock recovery so u can flash back if u need best way. u can make backup with twrp then when you restore u just got to flash stock img ir tar of recovery
Hi, I accidently rooted and installed cwm on my galaxy s4 gt i9-505, without disabling knox, and now I want to go back to the orginal samsung bootloader, (I don't not want to know how to get the stock firmware), I want to unroot and restore the bootloader, really need help asap, would be apperiated thanks.
Update: I'm on Android L 5.0.1, and installed cwm before rooting which was a silly mistake, because knox then countered that, and it's conflicting root problems when I tryed to root afterwards, but now I just want to go back to the Samsung bootloader, root issue fix but still don't know how to fix bootloader.
Not sure what is there to fix - if phone boots correctly it is good.
If you try to revert back to knox 0x0 I'm afraid it is not possible.
Flashing root and cwm doesn't replace your bootloader
How do you accidentally flash root and a customised recovery?

You are really mixing things up.
A custom recovery has nothing to do with Knox. A custom recovery gives no problems with Knox. It's impossible.
You are on the samsung bootloader. You cannot change it to a custom (there isn't even any).
If you want root just flash cf auto root and then delete knox. That's all.
Hello to all ..
is there any chance to root my S4 with the i9505XXUPPI1 version installed on it Or is there any other Way to Downgrade it to an earlier version and root it thereafter?
greetingz from Germany

You could try cfautoroot or flash TWRP and then flash supersu from TWRP.
CF-Auto-Root is your best option.
Thanks for your help.
For all i9505 Users with the same Problem ..
First i've flashed the original I9505XXUHOJ2 Firmware who listed on chainfire's Page, to be on the safe way =). Then i've flashed the cf-root Kernel from Chainfire. After that i installed the newest TWRP recovery and then the Resurrection Remix Rom 5.5.9.
Now i will test everything but seems to be nice till this moment =)
Thread can be closed .. Thanx
BTW, rooting is not required to install TWRP with Odin.

True. But some people (including me) have had problems getting TWRP to stick with the Odin install.
I had to use an app to flash it when I took to the custom software world.
A user had the same problem few days ago. Also solved it with the app method.
I've never had a problem with getting TWRP or CWM to stick on the s2, s3, s4, note 1, note 2, or note 3 by unchecking auto reboot in Odin before flashing recovery. Once recovery has been flashed, I remove the battery and immediately boot into recovery. I found that not booting into recovery right after flashing will cause the stock recovery to overwrite the custom recovery when the phone boots normally.
Thats right. But in my case and first of all i wanted to test the stock rom with only root Access. But then i decided to install a custom one very quickly =)
After all i installed latest twrp via twrp-app, backed up everything, perform a full wipe and flashed ResurrectionRemix 5.5.9. Now i went to dirty unicorn rom on Android 6.0 base. Very nice performance, very clear Design and absolutely stable.
One more word to overriding the Recovery. In many other Posts, this Problem seems to be normal, if the S4 was already updatet to an official lollipop rom(with the new knox Bootloader, that verifies signatures of recovery and kernel) in the past. I think this issue was not present with kitkat and oder versions.
But with my little detour, i also was not effected from that override
Hope this can help others with similiar reservations who i had before. Not the fear of loosing warranty(because phone is anyway too old) but fear of tripping the bad eFuse and thus hardbricking the phone. BUT WELL DONE !!!
Many thanks for the support .. And greetingz to all =)
There is no eFuse that will hard-brick the S4.
It only has an eFuse for Knox, which simply prevents you from resetting the Knox counter back to 0x0, but it won't hard-brick anything.
