This is gotta be at&t's fault no? lol I have t-mobile, it's for a friends s4. he's stuck on mf3

AT&T and Verizon have locked down bootloaders. When the OTA install starts, it blows a Qfuse making it impossible 'at this time' to downgrade back to a previous build.

So I couldn't use Odin to flash an earlier version of the baseband to also root, and stop myself from upgrading to mf3 again?

No. The bootloader is locked, and does not allow downgrade. Once you are on mf3, there is no going back.

No. It is impossible to downgrade anything. Read up on it. There is more in depth stuff than what I said. As of now, there is no way to downgrade, install a custom recovery, flash a rom, use Odin, etc. Only root is possible.

I was really thinking about rooting because i wanted to install this audio mod for music. That's really the only thing I wanna do. Also, to get rid of some bloat ware. But I still have very good battery

Root is possible, but if you mess something up, you may not be able to fix it until we get an Odin flushable MF3.be very careful with it.

If anything goes wrong with installing the mod you may be screwed. Also, saying you want to "get rid" of bloatware leads me to believe you want to delete. Don't, just freeze them.
I would wait--

Keep your eye on this app called Safestrap by Hashcode. It's being developed for Verizon S4 but most likely will work on AT&T's as well. Read more on what it is and other cool things about it here, be sure to read thoroughly so you fully understand what it does haha.

I'm on MF3 as well and I know how you feel. At least we can root.
Good things come to those who wait

If you can't be bothered doing a search don't bother rooting the phone.
Seriously, don't. You will just wreck it. It requires patience and a lot of reading.

I'm guess that you should wait until we get a leak ourselves or possibly the bootloader gets totally unlocked or by passed. or just flash one of the leaks back everything up and see what works or not.
Not quite the answer I'm lookin' for, but since u wanna be heard... Thank you for ur response!
Sent from my SAMSUNG-SGH-I337 using XDA Premium 4 mobile app
one you probably should state if your rooted or not. are you using this bootloader hack http://forum.xda-developers.com/showthread.php?t=2292157
and other things might be helpful. I've flashed most of the 9505 tw ROM 4.2 and had no problems with them have not tried any of the leaks or build off the leaks read that a few where having issues with wifi. I would probably just ask in the 9505 for if anyone has tried the leak.
There are a couple custom recovery (cwm, twrp...) flashable roms for the 4.3 leak.

I am not mf3 so already running Jamison's 4.3 from TMO forum--running great--I love it
well maybe in a few weeks for the US variants. but I would not hold my breath with att and verizon they have to make sure the bootloader lockdown will be enforced and they can put all of their bloat. http://reviews.cnet.com/8301-19736_...g-galaxy-s4-gets-official-android-4.3-update/
We need the source posted so that devs can mod the stock kernel. Not anticipating an Att release this month for 4.3
Still more interested to see 4.4 drop for the 9505g. Looks like that was really what key lime pie was going to be.

Update to MF3 or stay at MDL?

Been out of the game for a little bit due to a broken s4 but my question tonight is should I just stay at Rooted MDL or update to MF3?
Sent from my SAMSUNG-SGH-I337 using xda app-developers app
Don't do it
I STRONGLY recommend for you to stay at MDL, because as of this moment, there is no bootloader unlock for MF3, so that means no custom ROMS or kernels, unless you want to use SafeStrap. If custom ROMS don't matter to you, update. But remember, if you get TWRP, you can always flash an MF3 ROM and get it, while keeping your bootloader unlock. Try it. If you don't need custom ROMS and other cool stuff, update.
Lol just read about it and I defiantly do not want to update thanks for the help. So I'm safe to use any rom in the development section

Good one! I would say so to, but I'm tired of the boot loader issue. Although I have no desire to flash kernels, I feel when the boot loader is locked, it deters people from developing on the phone.

+1 I have a feeling all providers will be having locked bootloaders sooner or later... We all may have to go to Dev edition phones, unfortunately. But my next phone may be on T-Mobile (depending on if sprint buys it or not though)...
I,ve had the note 2 and 3 and can probably guarantee that I will get the note 4. My wife gets my hand me downs. Having a locked bootloader stinks but it helps that we can still obtain root and there is always safestrap though I haven't gone there yet.
