Flashing kernels? - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

So I'm coming from HTC where you need to have s-off to flash low level things like kernels, is that necessary for samsung phones?
Sorry, I'm a noob to Samsung...

No we are unlocked and can pretty much flash anything we want.
Coming from HTC you will want to learn about Odin and what it can do for you.

Thank you sir or ma'am.

CAllING DEV TEAMS !!

As we now have a working cm10.1.
Would it be possible for someone to port Sailfish OS or Ubuntu touch to i9505 jfltexx ?
Please like this post if your not a developer and this would be beneficial to you.
Thread bump
Please show support. No-one develops if there is no need for it in the community.
I'm sure the devs want to have an unlocked bootloader.

I9505 is the quad core version of the s4
I9500 is the dual quadcore (octacore with littleBIG architecture)
This thread is to request for the former.

Is there a way to flash it just like a ROM?
Sent from my SPH-L720 using XDA Premium 4 mobile app
I don't think so maybe someone else might know better.are you having problems with Odin?
Sent from my SPH-L720 using Tapatalk 4
Just not really sure on the process is it pretty much to flash stock back on so I can do updates? Or did it just pretty much replace the radios. The only reason why I really want to do this because it seems like my signal isn't strong I don't know if it's because I haven't done a PRL update profile update or if its just the ROM. I'm not new to routing and flashing ROMs. But I practically know anything about modems. I know you have to reflash the stock rom meaning TouchWiz to update profile and PRL but like a dumbass I deleted the stock rom backup.

If you follow the directions it pretty easy it only updates you're modem

How do I update just the bootloader?

I saw someone mention that freeza had a zip but I can't seem to find it. Thanks
Sent from my SPH-L720 using Tapatalk 4
What do you mean update the boot loader? I've never seen anyone ask this for a sprint phone. You can update , baseband and kernels which is usually what freeza has.
Sent from my SPH-L720 using Tapatalk 4
I dont think freeza is working on sprint gs4. If you want stock material, read the dev section for posts by crawj.
Sent from my SPH-L720 using Tapatalk 2
Freeza moved to T-Mobile when the S4 came out.
Sent from my SPH-L720 using Tapatalk 4
You guys are right , I was thinking about the gs3

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.

I wouldn't say all hope is lost. It's just a long shot. With any hope, the new Kk bootloader will be nicer to us.
