[Q] S5 official update to rooted device with official rom - Galaxy S 5 Q&A, Help & Troubleshooting

Hi,
On my S5 (SM-G900FQ) , there is original Samsung ROM (4.4.2) , rooted but with default Recovery.
I want to update to new official rom (Lolipop) and then re-root.
What is the most easiest and convenient way to achieve this ?
I can update to Lolipop rom through Odin. But then how can I get back root easily ? (without installing CWM if possible)
If I have to install CWM, which version should I use ?
Thanks.

I'd appreciate any help. There are lots of threads talking about root'ing but I couldn't find the one which works for Lolipop official ROM.

Would like advise on installing stock kitkat rom on my S4 i9505

Hi,
I would really appreciate some advice on installing the latest 4.4.2 update on my S4 i9505.
I've been using the MIUI CM rom the last few days but have found it too buggy (it's actually getting worse with updates).
I've also tried installing the Samy Delux rom, although it installs it just won't boot.
My phones boot loader is currently unlocked (no knox, early version of 4.1.2), I know if I install the new OEM rom it will install a secure bootloader.
Can someone please advise if my phone can be rooted if I install the latest rom for my phone and what the process is.
In the past I was able to install a stock rom pre-rooted, but from what I've read on forums that's no longer possible ??
Any advise would be appreciated.
you can root 4.4.2 but you will trip knox
and you can flash Pre-rooted Roms via Recovery

[Q] To root again after official update or not?

Hi
I have an I9505 which was at 4.3 by default. I used the CF-Auto-Root-jflte-jfltexx-gti9505.tar to root it and after that i updated it with odin and I9505XXUFNB8_I9505TSIFNB1_I9505XXUFNB8_HOME.tar that i got from sammobile.com .
now I don't know that after updating official rom, i'm rooted or not?!!
I flashed Trwap recovery again. I don't know that can i flash a custome rom now with it or i have to root again? if YES, the CF-Auto-Root-jflte-jfltexx-gti9505.tar will work again with android 4.4.2 or not?
thanks
please guide me.

There is an app called Root Checker which does what the name says. Usuallly, you can preserve root while upgrading if you got SuperSU Pro and have "Survival Mode" enabled.
You don't need to root for flashing a custom rom. You can just flash from the recovery.
Thanks
I flashed a new rom

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.

Installing KitKat with mobile odin

Hello! I need some help
My device is SM-N9005(hlte)N9005XXUGBOJ1. It is rooted,it has a custom recovery (TWRP) and a custom ROM flashed (resurrection remix). I have mobile Odin pro and here comes the Question..
I want to install kit kat on it and I did some research and it seems that I can't find the firmware on google. All I see is freaking Lolipop. Does anyone know where could I download the firmware? Also,as I earlier said,I have MobileOdinPro. I want to install KitKat with it. I flashed before stuff but using the PC. Now I have no PC and I really wouldn't like a soft brick so are there any steps that I have to make before flashing? Like downgrading the bootloader(if possible)?
Try the sammobile Forum .
