It says enforcing sepf_sph-l720_4.3_0010

So you're on MJA or MK2

I used mudavos method to upgrade to mja without the bootloader. But I ran into problems, so Im trying to check what Ive done. The phone works fine. I went into download mode to check if I tripped the knox counter but I couldn't tell because the letters were too small Im old. This is my wifes phone so Im trying to check this when she is not paying attention. I already lost all of her text messages so shes convinced I broke the phone.

If you dont have the bootloader then only only thing you could do is use odin to either mdc, mdl, or mf9 and start from scratch again. You will lose every data so its the only way to get it properly fixed again.

You can use either cf auto root and root the same way as you did with mdl or you can use crawj's mf9 stock rooted tar and odin that to get rooted.

OK thanks alot for the speedy reply. Didn't know if the cfauto root would work with the mf9 build. I did searh, but couldn't find anything. I did see the options u mentioned though.

[Q] Need some help fixing my phone

I have an AT&T i337 S4 running Android 4.3 MK2.
I was stupid and tried to flash a recovery that wasn't compatible, now my phone only boots into ODIN mode.
I've been looking for the MD5 files for 4.3 MK2 with no success.
Does any know what I need to do to fix my phone?
Go to best buy and have them reflash the firmware. If not there's a guide in the mj6-mj9 just search and read the forums.

Not really if you don't use Knox you shouldn't care much. I think I'm about to trip it after two months on stock.

One thing people have been confusing lately is a soft brick vs a hard brick. They freak out when theirs phones won't boot past splash screen. When your phone won't turn on at all. That is when you are hard bricked and are pretty much screwed.

Need help with updating

I have the official Samsung 4.3 update now. Mk2. I did not know it wasn't rootable with cf autoroot a few months ago and my knox counter is at 0x1. Would my phone brick if I updated to 4.4.2?
Thanks
Sent from my SPH-L720 using xda app-developers app
Simple answer is no it will brick brick. I was on 0x1 mk2 and took the OTA.

Using I337 S4 rooted unable to install safestrap unable to parse issues. Any help
Sent from my SAMSUNG-SGH-I337 using XDA Premium 4 mobile app
Ok everything worked good untill the custom rom flash.. It wouldn't leave the galaxy s4 screen.. So I had to re Odin the Damn thing because it didn't load safestrap anymore.. We'll. Odin failed for 2 Damn hours but after many failed attempts it finally got me back to NB1.. Then I refreshed NC1, installed towelroot and superuser and safestrap and changed to permissive.. Tried flashing a different rom (deadly venom) and every time I try to load it it just loads the normal firmware but on the custom slot.. So I'm not sure if I did anything wrong or if I should try a 3rd rom

I got golden eye to work on the main slot I think.. It's says that it's the build but it looks stock
Edit: after reviewing the goldeneye page.. It says stock look and feel so I'm assuming it's working..
