[Q] Need help installing Custom ROM on SPH-L720 MK2 Baseband

I used to have Verizon Gs3 and played a lot with Custom Roms.
Recently changed to Sprint Gs4.
I am on L720VPUEMK2 baseband.(Most recent Stock 4.3)
I did root my device by flashing CF-Auto-Root and Phil Touch Wiz 5.18.2 ( ODIN mode)
Here comes the challenge:
When I try to flash any custom rom using Recovery mode I am getting stuck at Boot screen with error.
Funny thing is If i use Cyanogen Mod Installer directly from My Laptop to flash 10.2 version.
I am guessing it has some thing to do with Samsung Knox Boot Loader.
Can some one help me with getting around this to flash custom Rom?

its been my experience with philz recovery once you factory reset you have to go into power menu and reboot into recovery again and then flash rom

So you are saying that Once I flash the Rom
1. Go back to Recovery and Do a factory Reset
2. Re-Flash the Desired Rom.
I tried this too.
Its not just Philz Recovery. I user CWM Recovery as well and having similar issues.

Use PC Odin to flash Philz latest recovery.
But in Odin don't check the "Auto Reboot". When Odin is finished unplug the phone and hard power it off or batter pull.
Edited for clarity - Meant AutoReboot

So when i did install custom Rom I am stuck on Samsung Galaxy s4 Screen
With Error
KERNeL IS NOT SEANDROID ENFORCING ( RED color)
Set Warranty Bit : Kernel (Yellow Color)
Its about 10 Minutes now and I will leave it that way for 1 more hour.
Update: its been 30 mins and am still stuck in that screen.

I'm curious as to what ends up happening with this. I was reading how to flash a custom rom, by using Clockworkmod Recovery.
It looks like the CWM is flashed in via ODIN after the root as a .tar.md5, then you factory reset/wipe data, then wipe cache, then wipe davilk cache, then install from .zip extSDcard. It seemed simple enough, and I have the same model as you, but it appears there are hang ups that you are having which I'll wait until I try it.
I also have stock ROM and MK2 GS4 with Sprint.

If you root with safe root you are correct, you won't trip the knox warranty flag. But you can't install a custom rom without flashing a custom recovery which is what actually trips the knox flag not root. So safe root is only good if you are going to run stock rooted and not install a custom rom.

My sprint s4 with Philz does the same exact thing, gets stuck at the same screen. Sometimes it takes a few then boots up , other times I have to manually reboot it.
I've tried many things myself and still this problem confines.
I've asked in other threads about this but no one had an idea of way.
The phone was on MK2, rooted with CF Auto, and has latest Philz.
I'll be checking in here to see if we can fix this... If it's even fixable. I think it has to do with Knox /new security.. But I'm no programmer so maybe a pro can chime in.

Hoping for some experts to help us.. May be a video on how to root of MK2 version And flash custom Rom will help us..

[Q] Flashed new TWRP now no recovery.

I installed the KOT49H GE ROM on my AT&T SGH-I337 and it runs great. I then decided to see if there was an update to TWRP and I found an updated one and flashed it via goo.im. I later read that this is not the way to do it. Anyway, when I boot into recovery a big yella triangle appears and at&t scolds me for running in authorized firmware. I can boot into download, cancel it and the ROM boots and runs fine.
Under the "about device" page on settings it says the baseband is MK2 (because I flashed that modem). If I look at the boot loader version via android terminal emulator it shows I'm still on MDL.
Any ideas how to get recovery working again?

I am trying to understand the reason why you flashed a recovery.
From your post, it looks like you are using safestrap and deadly venom tool to run GE.
You can flash the MLD files from the tool to get the recovery back.

I found an updated version of TWRP and thought it would be a good idea to update it. I think the problem might be that I didn't use Loki doki before I installed the twrp update. It can't get to the recovery now. Will I mess anything up if I use motochopper? I don't want safestrap because I like the Google Edition ROM and I'm still on the MDL boot loader.
I'm pretty much a newb with this S4. I had my S2 rooted with task650's ROM and understood that better because no locked bootloader

My bad! I read that you had "MLD" bootloader instead of "MDL" and hence my comment. MLD is a leaked 4.4 firmware.
Motochopper is used to root and I am guessing you still have root. All you need to do is flash a recovery.

Thanks for helping me out. I tried this yesterday and today with the link you provided. When I try to flash it via odin, it comes up as failed. On my phone, it says "SECURE CHECK FAIL: recovery" in red letters on the download page. Any other ideas?

You could try grabbing the mdl package, an extracting the recovery from it and flash in Odin or Heimdall. Worst case you flash to mdl and then motochopper it again.

Thanks. Do i need root to do this? I don't think I even have root any more. I'm running a custom ROM without root access. I tried to use CASUAL to root and install the recovery but it couldn't root it.

You will only need to root again if you go all the way back to stock.

[Q] Phone won't boot

Greetings all
I recently tried the root process that was developed by geohot (http://towelroot.com/) on my s4. It worked to get root and unlock the bootloader (I thought). When i tried to flash a custom recovery to it, it failed and now the phone won't even boot normally at all. Can still get to Odin but can't get to Recovery. When I tried to Odin the stock ROM to it, it fails immediately.
Got any ideas on things that I can try to do to fix it, or you think that it's hardbricked now?

You will be able to Odin flash the full NB1 firmware. The link is available in the all things at&t thread

Also, towelroot only roots. There still is no custom recovery, the bootloader is still locked

Problem installing custom recovery using Odin

Hey guys, I'm pretty new here and new to rooting devices. I recently just rooted my Samsung Galaxy S 4 SGH-1337 (At&t) with the new "TowelRoot" and then using Super SU to finish the root. I has a question when it came to installing the custom recovery Philz Touch. I have the 4 most recent versions of PT and using Odin v3.09 and v3.07 I am still unable to correctly install the recovery. When I try starting the process I get a "Leave CS" in the bottom left of the Odin window, and when I start the process fails? I've noticed when I go into download mode on my S 4 the phone tells me on the the official binary and official operating system. If I am rooted should that say something else? I have checked the Root Checker app and it says I am in fact rooted.
Other solutions I've already got advice and still unable:
- I'm using my out of box charging cable.
- I am pressing start after I ad the AP in Odin.
- The phone is in Download mode.
Can anyone help me out and assist me? This is super annoying and I would love to figure it out soon. Thank you in advance!

Since towel root worked in your phone I'm assuming you're on firmware nc1. This can not have a custom recovery installed. In fact you probably erased your stock recovery trying these other ones. I suggest using odin to flash nb1 then update back to nc1 and if you want a recovery yo install another rom (only touchwiz based roms) you'll to use safestrap. That is the only option at this time.

Thanks for the response. I am on firmware NC1. After posting I have read that there is a new bootlocker (?) that was pushed on the 4.4.2 update preventing people from actually installing custom recovery and other things. There is a workaround going to an older version to then root and get a custom recovery, but I definitely don't have the knowledge of what to do.
I'm not sure what you mean by me probably erasing my stock recovery? Are you saying if I try and restore my device it will not work?

When you tried to install the custom recovery it more than likely erased your stock recovery and the only way to get it back is to flash nb1. And going to an older version is no longer possible. Once you update and the bootloader is updated you're no longer able to revert to an older bootloader. Trying to do so could brick your phone

Again, thank you for responding to me. I understand what you are saying now about me possibly deleting my stock recovery. I didn't go very far i the process and I'm fairly sure I didn't for the simple reason that it did not work. I can definitely be wrong and you are probably more right on this situation than I am.
Thank you for the heads up with the older version not possibly anymore.
Do you know any confirmed ways of rooting and flashing a custom recovery since 4.4.2? If not I guess I'm just going to wait a bit for a confirmed method.

Before proceeding check to make sure your stock recovery is still intact (power phone off, wait 10 seconds, power on while holding volume up/home button/power if you boot into recovery you're fine and can proceed with towel root (just Google it it'll come up right away) download and install the apk on your phone and it'll root your phone for you.

Closest thing to custom recovery that will let you only flash touchwiz based roms.

I9505 rooted but cant install custom recovery

EDIT: Sorted it, flashed TWRP in odin and it worked this time.
I have rooted my i9505 (5.0.1 stock Baseband i9505XXUHOD5) using CF-auto and Odin but I cant install a custom recovery. When I try in odin it says pass but then gets stuck in a loop at reboot. When i go to recovery its still stock and the only way out of the loop is to factory reset abd then try again. It looks like a Vodaphone Germany rom thats been unlocked installed. Any ideas please? I want a custom rom to get rid of the Samsung crap in the background.

Thread can be closed
As you have solved it,like this you open this thread for nothing
And also, CWM and Philz are outdated and out of support(only for this device), always use TWRP[emoji6]
