Going back to stock rom without losing root? - Galaxy S 5 Q&A, Help & Troubleshooting

How can I go back to stock ROM without losing root access? I'm running the CM-12 5.0 Lollipop ROM right now (I believe that's the name of the ROM)

Unfortunetly, it`s impossible to go back to stock ROM without losing root access . But it`s not that hard to root stock one again.

If you want to remove root:
- Use Triangle Away to reset the binaries and system status to official
- Unroot from within the superSU app
- Flash the rom with Odin
- Data factory reset
If you want to keep root:
Use Mobile Odin Pro to flash the new rom and keep root. Check inject superSU, Everroot and the other option.After it reboots do a data factory reset (root will stick btw).

No it's not safe nor recommended. If you had done a search you'd find dozens of threads asking and answering this question in existing threads. Accepting an OTA update is likely to break root and sundry custom ROM features.
You should refer to the custom ROM support thread where the developer will either tailor updates for your ROM. Or at least power users will discuss their effect on the ROM and how to best apply an update to your particular ROM.

OP is talking about flashing a full stock rom with Odin as i understand , not about getting or installing OTA`s as he is on a custom rom atm

[Q] Root 5.0 without setting of knox

Hi.
Question, is there a way to root 5.0 (stock) without tripping knox?
Tried to search\google it, nothing came up.
It's very important to me not to set off knox I still have warranty.
please help :fingers-crossed:
Device model SM-G900F
Nope not really
There was some info about downgrading to KK and rooting with towelroot, then using Mobile ODIN Pro to inject root into a stock Lollipop ROM and upgrade that way, never got that working myself though
No way to directly root stock Android 5 on the Galaxy s5 without tripping knox. However, you can downgrade to a stock 4.4. ROM and then use Towelroot. Afterwards you flash Alexandr's prerooted Lollipop ROM. There are guides everywhere, you could use this one for example https://www.reddit.com/r/galaxys5/comments/2ubsbs/guide_rooted_android_50_for_the_international/

Thanks!
Can I just downgrade to 4.4, root it and leave it like that without upgrade it back to 5.0?
Yes, you can. No one is forcing you to use Lollipop. I find this thread very useful: http://forum.xda-developers.com/galaxy-s5/general/how-to-root-triggering-knox-2nd-method-t2843044
If you just want to use towelroot on 4.4. follow the root instructions and do not flash the Lollipop firmware afterwards.

Is there a problem if i update to latest stock rom?

Hi,
i want to buy a new note 4 - the version 910f.
If i update the new phone with stock 4.4.4 rom to the latest 5.1.1 - will there be any problem if i want to install root or anything like this later on? Can i still install custom roms?
I want to now this, becqause if i update my new amazon fire 7 (2015) to latest stock 5.1.1 rom - there is no chance to start recovery anymore for installing custom rom. With only 5.0.1 all is good and i can install custom rom with recovery.
Is there a similar problem with note 4 or can i install latest stock rom and won´t get any problems later?
Only thing i found is that i can´t go back to 4.4.4 when installing 5.1.1? And i can´t go back to 5 when i´m installaing marshmallow because of changing partitions size?
So if i go to stock 5.1.1 it doesn´t matter, because i don´t want to use 4.4.4 and i can still use all stock roms and change to marshmallow later?

No problem if you don't plan to use 4.4.4. Note that if you update to latest 5.1.1
>your bootloader will be locked you can't go back to previous roms or use custom roms which are based on earlier versions such as 4.4.4 custom roms or 5.0.1 custom roms.
>you can still root your phone install custom recovery and install custom roms which have newer bootloaders. However rooting 5.1.1 is bit different because with android 5.1.1 there is an extra security layer in the kernel which detects and stops device from being rooted you need a "permissive kernel" to root 5.1.1. And then you can do whatever you like.
Would it be a better decision to stay on 5.0.1 for the moment and later install 5.1.1 custom rom? To not loose unlocked bootloader?
And one more question: if I deactivate bloatware in application setting off stock rom, is bloatware complete deactivated or is it still running in the background somehow?

You can install 5.1.1 with these bootloaders coj3, coi3, pok1 , coh4 these are safe and won't lock your bootloader. i'd recommend 5.1.1 over 5.0.1 because the difference is day and night in long term use (when u have many apps) 5.1.1 is much smoother and better battery life just don't install coj5 or newer bootloaders. I don't use custom roms because in my experience stock rom is the best custom roms have some bugs etc. If you deactivate bloatware in application settings then its no more running in background.
OK, thank you. But so I should deactivate ota updates and flash latest stock update with Odin, so that I don't get latest locked bootloader?
How can i update to latest 5.1.1 update and keeping the (old) unlocked bootloader?
Do i have to donwload version from smamobile and flash with odin? How can i disallow to update bootloader too?
And if i update with ota - i will get latest (locked) bootlader automatically - no chance anymore to remove it?
-----------------------------
I don´t want to root my phone the first time (because of knox) but later on i maybe want to root too.

There is no way to be sure if the older bootloader will work with latest 5.1.1 rom. So its better to stick with the bootloader which comes with the rom and yes if you update with OTA you will get latest 5.1.1 and bootloader automatically. Just go to sammobile and download 5.1.1 with COJ3, COi3, or POK1 (nordic countries). and Flash with odin.

update stock rom without loosing root

Helo guys ,have anyone update rom without loosing root? mean can we update rom flashing stock recovery only.or we have to unroot stock rom?
Root has nothing to do with having or not having a stock recovery. So the answer to your question is yes you don't have to unroot.
