Hi guys,
I have the following official rom :I9505XXUFNB88
I only rooted the phone using towelroot with Knox 0x0. However after two years of using it and now loosing my warranty I would like to update my phone to 5.0 or even flash a custom rom 6.0.
Theres a small hiccup, I can't ota any update because it shows me an error when flashing. I bet it has something to do with towelroot.
Do you know how to disable it?
Many thanks!
Download a ROM from sammobile, using the device model, and narrowing down the results by country and carrier. Flash that ROM through Odin, as it will be the latest provided by Samsung. That will upgrade your bootloader and baseband to the latest versions. From there, download the latest TWRP recovery available (link in the AOSP 6.0 thread located in I9505 Original Android Development) and flash that through Odin. Then flash the custom ROM of your choosing.

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
Hi, I'm currently using Alliance rom with firmware ang2. Was just wondering if it's safe to flash an updated firmware like ang9 for G900f device. Thanks

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

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.
Install Custom Recovery Samsung Galaxy AT&T S4 SGH-I337 Ver 5.0.1 Non-Rooted. OK2
Hello, I Want to do some modifications to my Samsung Galaxy S4 and Have so many questions that I am not sure were to start? Yes I'm a noob but learning. I have a SGH-I337 phone that is unlocked so I use it for T-mobile. The phone came with KitKat 4.4.2 NB1 firmware but I managed to update it manually to the latest firmware OK2.
What I would like to do is install a custom recovery and install a clean non bloated Rom. Maybe a custom such as CyanogenMod? Questions: Is there any recovery software that will work on my present upgraded phone such as Safestrap, TWARP,PhilZ or CWM and in doing so I am guessing I need to root my phone first? When you root a phone does that unlock the boot loader? I have read articles saying you can only install custom recovery on the older firmware such as kitkat 4.4.2. or unless a update comes out. I also have read articles that I cannot downgrade and am not sure what that means as I have read articles that I can use Odin and reinstall my stock firmware NB1 is that true? Is there a way to downgrade your upgrades?
I see a lot of articles how to install recovery software but they do not always say what firmware version they are installing it to so I wont even try it. I am guessing-it is the older firmware 4.4.2.
I have read I can flash my kernel to an older Kernel such as NB1 then root it install a custom recovery then upgrade the kernel again? Not sure it I can upgrade or downgrade kernels that are for my phone?
I did manage to root my phone awhile back when it had kitkat 4.4.2 NB1 but had problems later on with my touch screen going crazy as if someone was in my phone so I brought it back to stock by using Odin and reinstalling NB1 firmware hoping to fix the problem. After installing stock firmware I decided to upgrade to lollipop 5.0.1 OB2 and that is were I am now. About my touch screen going crazy I have been reading it may be due to cheap USB chargers which I am using but that is another story.
Well any-help or leads would be appreciated.
Maybe if I wait long enough someone will come up with a custom ROM for my latest firmware as well as rooting it?

Hi, I meant SGH-i337 in the title.
I beleive I posted this in the completely wrong phone section last time, so I am posting this here.
My device model is the SGH-I337. I downloaded Odin version 3.12.3, downloaded the official drivers for the Samsung S4 USB, but I can't seem to find stock Lollipop 5.0.1. SamMobile only gives the 4.x versions for some reason. I started following the below link for a method to at least flash an older firmware to my phone, but I want to flash stock Lollipop. Is there even a way to get Lollipop back without root?
https://forum.xda-developers.com/galaxy-s4-att/help/guide-att-samsung-galaxy-s4-sgh-i337-t3383078
I was able to downgrade, but I still need an official stock 5.0.1 firmware. My virus protection says towelroot is a virus, so I don't want to go that route. If I do an OTA upgrade after I flash the old firmware from the above link, will it brick my phone? It's rootable NB1 ROM. I already tried to install the stock 4.x firmware from SamMobile, but that doesn't work, so it seems I need stock Lollipop.
AT&T never released a stock lollipop firmware that can be flashed with Odin. All at&t updates were released ota.

Hi I am running goldeneye custom rom on my i-337 5.0.1 with ok2 kernel. If you go to that forum thread in development, you will find very detailed instructions to get att s4 to 5.0.1 stock. As a side note I can assure you if you just download towel root on your phone, install and run there is no virus of any sort. Make sure you download from towelroot .com
On second look through I don't think there is stock 5.0.1 using safestrap....
