I just purchased an unlocked stock I337 S4 from Ebay that I intend to send to the Phillipines for my fiancee. It currently has MK2 firmware. I would like to upgrade it to OC4 before I send it overseas. I tried using ODIN to flash it to OC4, but it fails.
I managed to root it using Saferoot, and that worked except now it has a lock icon and says CUSTOM on the boot screen, but it still boots fine.
Anyway, I have been reading through this forum for about 3 hours now, and have found no sensible way to update this phone. Even if I could just update it to 4.4.4 I would be happy. Do I have to upgrade it step by step through all the firmware updates? Do I really need to have Safestrap installed to do a stock upgrade from a stock ROM?
Any links that could be provided to make this an easy process would be most appreciated..

Snapping along on stock rooted 0C4 I337, wishing for some good up to date lollipop ROM's to throw into flashfire

Hello, I've been out of the rooting scene for over a year now since I bought my Galaxy S4. When I first bought it, i had it rooted but could not install a custom rom because it was on MF3. So, once again I am trying to get back into rooting with the latest OTA update and a NC1 baseband. I've been looking around on how to root and install a custom rom but I've been gone so long that I'm just lost.
From threads I have read I can downgrade my phone to NB1 then to MK2 to root. However, I haven't really been able to find an answer to if I can install a custom rom to it, only upgrading back to the OTA and keeping root. I have been having massive overheating problems with the stock firmware and have a large burn mark on the back of my phone and would like to switch back to CWM which i had on an old phone.

No CWM. You can only use Safestrap, a variant of TWRP for locked bootloaders that doesn't flash kernels. Due to that restriction (if we tried to flash a custom kernel we'd get bootloader check fails) we can only run ROMs which the stock kernel supports, meaning other Touchwiz ROMs and the one GPE that's been posted in the General section. Part of the downgrade and root process is using Safestrap to update to 4.4.2 with a modified OTA, and so you just replace that step with flashing a ROM, the kernel modules, and then the ODIN files.
I have another S5 I am running 4.4.2 on and would like to load the MOAR Rom to it. How can I do this and get around the Verizon warning about unapproved software? My phone is rooted and had Safestrap 3.75 right now. I tried to load the MOAR Rom via safestrap and got the unapproved software warning. Thanks! I am a noob with fighting these super locked down things from VZW.
I would lke to know the same thing
This is my recommendation as to i don't care to flash anything higher than OD5. You can flash Muniz_ri's to OC4 and keep root ROM and from there flash away to any ROM in this Forum section and update the firmware by flashing the latest firmware NO Bootloader Zips. Again that's what I do and haven't had any issues and i can Odin back to NCG and "officially" run a KK ROM. Also, I'm currently running the MOAR ROM and on the latest firmware which is PB1. Was running Jrkruse's Norma Note5 ROM but went back to MOAR for the moment....
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?

I was rooted, running sacs custom rom v5.6, an android 4.3 rom on mk2 baseband and firmware. It's been on these BB/FW for a long while now.
Sounds stupid as I type it out, but I want to play pokemon go. It requires 4.4.2 or newer android.
I went to sammobile and downloaded the newest stock, ok3.
I flashed it with Odin and it took, booted right up. I go to check BB and FW, still on mk2. Using the menu to try and get it to update the BB and FW doesn't do anything other than tell me I have the newest version. I can't flash this custom ROM I want unless I am on one of the newest firmwares.
Wll, I got angry and flashed stock mja. It's currently sitting on the yellow Sprint screen, it's only been about 5 minutes so far so I might give it a chance for the next few minutes... (25 minutes later I gave up and reflashed ok3)
How bad did I mess up?
Can I go back to stock mk2 and have it update itself to ok3 (or download and flash manually with Odin)?? I briefly looked but I couldn't find any ok3 modem only, and I was under the impression that I needed the full firmware to get the newest TW ROMS working anyway.
Download mode shows knox is 0x0.
What can I do to get it updated fully? I can root and flash again after updating if needed. Any help is greatly appreciated.
I flashed ok3 in odin again and am now on ok3 baseband and firmware.
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?

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....
