hi,
I want information,
if I install the upgrade to Android 4.3 on my s4 SGH-I337,
I lose root and recovery?
thanks
Are you upgrading using official Samsung ROM or custom 4.3 ROM?

If you upgrade to the Official Samsung OTA from 4.2.2 to 4.3 there is a possibility that you will lose your root and 100% you'll lose your custom recovery. Due to the locked bootloader, you won't be able to flash a custom recovery onto your phone.
If you were on MDL and you did the update, you are now locked down...
Should read a little more, before jumping on updates.
Good luck.

Is it possible in someway to upgrade your Samsung Galaxy S4 software to vanilla 4.3 without using a custom recovery? If not, if I install stock 4.3 on i9505, will I be able to recieve OTAs that will come in the future?

If you look here you'll find many ROMs that claim to deliver the "nexus" experience. I haven't found one that could be flashed via Odin, however. You can root your phone and create a full backup of your ROM, and then install CWM or any other recovery manager to flash the one of the nexus-experience ROMs. You can always go back to the Samsung ROMs if you don't like them.

Thanks. I found my answer in that thread. It is not safe to accept OTAs on i9505 because of the different bootloader/radio that i9505GE have.

Hi...
I am a nexus user.. When a Google update comes out. I just look for rooted version of update and I install it. Or I install ota and reroot.
Now I have s4.. Rooted.. And cwm recovery. Mk6 is out... I Dont know what to do. I Dont want to erase my setup. Do I just wait for someone to post the update? Flash it with cwm or Odin? Do I unroot first or get a version that is rooted?
Any help to direct me with my options for upgrading so mk6 without losing cwm or root would be appreciated.
Thanks.

best option is to update the baseband using the modem file here http://forum.xda-developers.com/showthread.php?t=2542043 which you install using Odin
then flash a 4.3 rom such as GE using CWM
this avoids any issues with the OTA or stock 4.3 firmware, retains cwm and root and gives you the functionality of 4.3
Thanks for the reply and info. Ok.. So modem I can follow instructions in the thread above. No problem. But where do I get mk6 flashable file? What is GE? I am currently on rooted samsung stock 4.2.2. Is GE a custom ROM? Normally when flashing a custom ROM u need to start clean as far as I read. Can I just update my stock with stock? Any one takes ota from samsung and adjust to prevent losing root and cwm?
Thanks

Just figured you mean Google edition .. I understand I can go Google (which needa wipe) but that is not what I am asking now. I would like to update my samsung image to mk6 (4.3 without wipe). If I wanted to go to Google image I would have updated long ago when 4.4 came out but I have been waiting for Samsung's update.
How do samsung rooted stock users update their phones?

Hey guys so i have heard that if i install the old firmware for my s4 from sammobile using Odin one from early 2013 that it will give me access to service menu so that i can unlock my phone. So my question is that is it 100% safe to Odin flash the older 4.2.2 rom when i am on 4.3? Can i flash it unlock my phone then upgrade my phone to a custom rom again? Thank you

Do not do this. This will brick your phone. If I am not mistaken, there is a method to unlock mk2 in the general section.

You should ask this in the t mobile s4 forum. I believe your bootloader is unlocked and you can flash an older firmware version. But check there first. This is the att s4 forum. It can't be done on the at&t s4.
Is the service menu missing on the stock T-mo 4.3 ?
Nooo guys i have an unlocked bootloader i have the s4 that is very similar to the tmobile and it's the same as the Canadian versions. And yes the Canadian version which is 1337m and mine which is m919v don't have access to service menus but i have flashed a lot of custom roms simply by philz recovery so doesn't that mean i have an unlocked bootloader?

If you're on 4.3 I believe you also have Knox, in which case I don't think you'll be able to go back to 4.2.2. Read through this http://forum.xda-developers.com/showthread.php?p=40903040

Did you ever take the ota to 4.3? Do you know what firmware your device is on? A 4.3 custom Rom wouldn't have knox but if you took the official update to 4.3 you would have Knox.

Hmm i think then yes i might have knox. I think at one point i might have been on stock 4.3 is there any way that i can check to see if i have knox? And if i have knox i cant flash an older stock firmware for my s4?

Idk, I'm not that familiar with your device. From the little bit of reading I've done I would say no, you can't flash an older firmware. But again, I'd post this question in the t mobile forum. They'd be more familiar with your device.

Did you ever update you device with kies or ever take an over the air update ? It's fine if you were on a stock based 4.3 rom as long as you never took an official update. If so then you can't go back. Just flashing a stock 4.3 rom won't change that status but the 4.3 bootloader would.
You would have know by checking in settings under SE

Hi all, I have a galaxy S4 that is still on android 4.4.2, Build number JDQ39.I337UCUAMDB. What is the proper way to get this updated to KitKat so that I can use towelroot?

If you're on MDB, you can use motochopper to root and have a true custom recovery to run ROMs like Cyanogenmod, Paranoid Android, Slim Bean, and other AOSP ROMs. If you update you're limited to touchwiz ROMs of only the same system version you have.

I assume you meant Android 4.2.2...
But yeah, your on MDB so this what I could recommend...
(Optional) First, use Odin and update your phone to MDL using these files. I can't recall if MDB works the same way as MDL (via Loki), it doesn't hurt to update to MDL though.
Secondly, after you have successfully flashed MDL follow this guide to obtain root, install a custom recovery, and learn how to use the Loki exploit.
Whatever you do, DO NOT let your device update to MF3, MK2, NB1,etc as you will lose the ability to run non-TouchWiz based roms.
Personally, I'd recommend just going with pure CyanogenMod after you get your device ready to go. You may want to do a little more research however, my experience with pre-MF3 devices is limited.
Hi guys!
My dad has been using the above mentioned device for the past 5.5 years. The device is running a stock rooted 4.2.2 MDJ build. His bank is about to stop the support for the 4.2.2 version so we need to update the OS. The minimum required OS is now KitKat but I would like a more moderate ROM. Is it possible to have for e.g. an Oreo based ROM without Knox? In other words, do some ROMs include a Knox bootloader (to enable them to run)?
Thanks for the help!
Only Samsung ROMs would contain Knox.
The apps should be fine with a stock 5.01 ROM if you want to stick with stock.
If you want to run a custom Oreo ROM, I suggest flashing the latest bootloader and modem before installing Oreo.

Thanks for the reply!
As I said I would like to evade to flash the Knox bootloader. I know Samsung made it impossible to use their OS without Knox so I'm guessing my only option is to use custom ROMs. Are there any ROMs that still utilise the old bootloader?
You can't flash any bootloader other than stock.
Knox will not interfere with flashing custom ROMs.
Some banking apps will not work with a rooted ROM so you may have to use another app to hide root.

Root is in place just to disable OTA and by the looks of it the banking app doesn't care.
Regarding Knox, I actually think of it as a security downgrade because the NSA played a part in its development and they are known to spy on people. I feel safer when it's not installed LMAO
Is the phone an sgh-i337m or sgh-i337?
The sgh-i337 was made for at&t.

It's the SGH-I337M. Canadian model. CSC is TLS (Telus)
Okay, just wanted to make sure it wasn't the att model because the 4.3 or newer bootloader is locked on the non-m version.
Anybody have any suggestions for a ROM? It doesn't necessarily need to be the latest version of Android. It just needs to be compatible with the old bootloader
If you're still on MDJ stay on MDJ, don't update your bootloader, only the modem. 4.3 don't have KNOX, just don't update from OTA.

Don't worry. I won't I am just looking for an at least 4.4 ROM without Knox
AFAIK Knox is on the 4.3 build
Here are a few pics if some of you still don't believe me
Anyone?
Heard also Chrome is losing support for Android 4.2.2
