I have a Sprint L720 running a odexed stock MK2 rom from circa 2013. I followed all the steps back then flashed a custom recovery and the rom for the hotspot capability and am still extremely happy with how it turned out but... I want all those fancy new features lol. I don't really need anyone to hold my hand through the whole process but I did reformat a few times since then and have a couple questions before I start paperweightin' this.
Everything on here is MK2. Software, Baseband & Build. If i wished to flash a newer lolipop rom to my L720 would I need to apply any updates first? Can I flash the new rom from the custom recovery? I attempted to upgrade the firmware through Kies but keep running into a device not recognized error that I suspect is because I'm rooted. Anyway thanks in advance for your time!

AT&T S4 with 4.2.2 MDL. I rooted it way back when. I have CWM recovery installed. No AT&T Updates have happened because they always fail At the same time what are my options for getting 4.3 or for that matter when 4.4 comes out?
I have bloatware still. Use root for backups and a few other root required apps. I've run custom roms before when I was on my HTC Evo 3D. If I install a custom rom will I loose my current root / status?
If you want a stock rom minus bloat...

I would use these as starting points because they're modded slightly and if you want more, explore other roms.
Make sure you update your recovery to avoid any errors in flashing. You can also flash to the latest radio and revert if it doesn't work for you.
You won't lose root. You already have recovery, so you can always get it back.
There are 4.3 custom roms out there, there are people who want an S4 that came with MDL. I'd flash a custom 4.3 rom. We can even ugrade (flash) our modems to MF3, MJ5, MJ6 and flash back to MDL without ruining the phone like those who took the upgrades prior to root and got screwed by Samsung.
Do some research like above and for gods sake dont unroot your phone and take any OTA updates or you will regret it.
Just my advice.
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.
So I have a GS5 on KitKat running NI2 Firmware and Build. I Flashed Ricks ROM and am loving it! Big ups to the Dev on that. However, the whole reason that I Rooted my phone was to try out custom ROMs and my question is if I wanted allianceROM on my phone, I'm currently on Ni2 instead of Ne9. Could I only change the firmware and not the entire build to Ne9 and then flash the AllianceROM? I know after all these years, I should know this by now however, I just waited for in this case an Ni2 rom build to be released then flash it. Is there a way to try any of the builds within kitkat?
I know that the phone needs an update to try Lolipop, but not willing to give up on my perfectly running kitkat Rom (just yet)
Any help is very much appriciated!

Odin the NE9 firmware, boot into safestrap recovery before your phone boots all the way up, then install the NE9 ROM ( which should already be downloaded onto your phone). Don't forget to wipe first.
Hello,
I have a rooted i337 with MDL baseband, running stock 4.2.2 firmware. I am currently out of the US and therefore cannot receive any OTA. I want to upgrade to Lollipop or Marshmallow based custom ROMs, esp those that can still use the IR feature of the S4.
Can anyone guide me on how I do this upgrade, without bricking my phone? Would truly appreciate your help. Thanks.
Have you tried running ota updates via wifi without a SIM card in the phone.
To run a custom rom, you would need to install a custom recovery to flash the rom. Some mm and LP ROMs may not work with a 4.2.2 modem and bootloader.
If you want to use a custom ROM, DO NOT take any OTA updates. If you take an OTA and it is successful, then you will no longer be able to install a custom ROM.
Here is the Cyanogenmod thread to install CM to your phone: http://forum.xda-developers.com/showthread.php?t=3008609
If you would like to update to official ATT/Samsung lollipop(there is also a way to have root)[remember, once you take an official update from MDL, then you will no longer be able to install a custom ROM and you may never be able to get Marshmallow]: http://forum.xda-developers.com/showthread.php?t=2926642
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?
