What firmware was on the phone?
MDB/MDL or MF3?
If MF3, you have softbricked your phone and may need to go to Best Buy to have it fixed.
Review the Stickies in the General section about MF3 (if you haven't already).

Looks like I'm mf3 but I'm still able to use my phone normally.
Is there a different unlocking method or am I missing something?

Good to hear you didn't soft brick your phone.
MF3 has a locked bootloader that no one has cracked yet.
Read through MF3 stickies in both the General and Q&A sections for more info.
Long story short, you can Root the phone then use Safestrap as your recovery to install custom roms.

I would like to update to mf3 but after doing the ota update it reboots to recovery but I now have twrp instead of the required stock recovery...
After doing a lot of searching the only solution I found was to flash the official firmware with odin, but I'm assuming I will have to do a factory reset after this?
Is it possible to replace twrp with the stock recovery without having to do a factory reset or is there another way to get the mf3 update with twrp? (I'd rather not have to re-install all my apps and settings)
I hope my questions make sense its late and I'm tired.

There is always a risk of screwing something up...so read the thread, follow the directions, and decide if you want to take the risk..it's your decision.
Why not just flash a sweet custom rom like omega v9.0? That's the best thing about a custom recovery. It makes it easy to back up your current content and then try out a wide variety of mods and roms.
It's kinda counter productive to flash a stock recovery when you are trying to mod or customize your phone.
Odin is the cats butthole when trying to return to stock. Also, read the poop out of these threads... somebody has done what you want to do already so most things can be resolved with the solutions others have presented.

The OP said he wants to update to MF3. I can't figure out why anyone would willingly do so either, but it is his decision. Personally I would also just flash one of the MF3 ROMs or International updated ROMs and still have the ability to use custom recovery with the benefits (I don't really think there are any) of MF3.

thanks god did not turn my cell into a $600 paperweight :laugh: ... the process worked, but, when I try to do a factory recovery a sign from ATT says, in the top:
Secure Fail: Kernel
and a yellow exclamation with the following message: "System software not authorized by AT&T has been found on your phone. Please turn off your phone and go to the nearest AT&T store for help."
has anyone seen this?

You can flash your recovery with fastboot command:
Code:
fastboot flash recovery /path/to/revocery.img
I ended up just flashing the modem it seemed to be the safest option

I'm sure MF3 will be unlocked eventually, but for now use Safestrap to flash your device. Make sure you follow the steps carefully or you could end up bricking it. As for Odin, I don't believe so. Samsung Kies it self isn't even updated yet for the MF3 Kernel support; it doesn't even recognize it for emergency restores.
I'm so scared about getting hard bricked again. i sent for JTAG before and they took 60 bucks for repair. i will wait untill MF3 stock comes out for Odin.
I just installed safestrp on mine less than 10 minutes ago, it worked like a charm. The instructions are pretty easy as long as you pay attention to what you are doing its a snap

Safestrap WILL NOT brick your phone as it does not touch the MF3 and makes a whole nother partition instead, also bestbuy can unbrick your phone free.
Still be careful cause people are not following instructions in that thread either and are flashing over there stock rom slot.it can be done just dont do it.i use Safestrap and MDOB rom and works like it did before I chose to take the MF3 update.so easy

I haven't seen much mention about putting clock work recovery on with MF3. I was able to flash it on my Galaxy S4 1337 MF3. Is there a reason I dont see any posts about CWR and MF3 besides there being no stock firmware? Also, will my CWR work like non MF3 users? For some reason I dont see a backup option in CWR...

Well with MF3 we aren't able to flash custom recoveries because of the locked bootloader why he seems skeptical but if you say you have MF3 baseband and CWM then that's interesting.

I see. Is what I did was follow the "new root method" for MF3 and I downloaded CWR from play store and flashed. When I boot into recovery it works. Although I haven't flashed anything. I also dont see the backup/restore selection. The
Maybe post up some pics of your baseband and with CWR the skepticism might go away.
Take a pic with a different phone if you have to.we would all like to use a custom recovery with no limitations.

I'm willing to bet you installed the ROM manager APK, which IS NOT CWM. One of the features of ROM manager is the ability to install CWM on some phones. The AT&T S4 with MF3 recovery IS NOT ONE OF THEM! If you actually attempt to install CWM on it, you will brick it (at least soft brick). You are most definitely getting into stock recovery. I suggest you put your phone down and learn about what is happening with it before you can't use it any more. There is a ton of information about this in the forums already. Even a little simple reading without searching will point you in the right direction for this information. If you continue to insist on having put CWM recovery on an MF3 phone (and it is still operational) then I suggest you post a screen shot or picture as requested.

Well I booted into recovery and it must be the default one (not CWM). All the options in there got me confused plus when I flashed it said successful. I should have paid more attention to the recovery mode. I saw clear cache and figured it was CWM.
I'm running mf3 unfortunately and am looking to upgrade to 4.3 w/o using safestrap.
I'm rooted and am hoping to retain that feature.
I was wondering if I could upgrade to the latest mk2 att ROM then reroot or if the Knox would prevent me from doing so (or if this would just void my warranty).

Well everyone is going to want to be able to have the boot loader locked on 4.3 on mf3 you got safestrap already so correct me if I'm wrong but some people are past trying to get the mf3 unlocked and are working on the 4.3 now.

Hmm that's interesting. I figured that unlocking the bootloader would be easier with an older version and that people that already started it on 4.3 would continue trying rather than starting back from scratch with a new bootloader.
Is there a new threat for the unlock status on mk2?
Follow this thread right here there's people just throwing out ideas to get the boot loader unlocked and people that are willing to try the ways to.

My Phone BASEBAND is I337UCUAMF3
1.How do I know if my bootloader is unlocked or locked. When I go into download mode, will it say like bootloader=locked/unlocked or so.
2.If its locked. How do i unlock it. Secure or non secure. Just wanna install CWM/TWRP Recovery with updates straight from there site without a need for modification like safestrap. Wanna install custom roms A.S.A.P

Any AT&T I337 that's MF3, MK2, or NB1 has a locked bootloader so don't bother checking. So far there is no exploit, Devs are working on it and when they crack it it will be all over the S4 threads. Safe strap is the only way to run custom roms. Don't try to flash a custom recovery.

Thanks a lot for your speedy reply. So upgrading my Baseband to something else wont change the bootloader locked? I am also guessing every AT&T S4 comes bootloader locked then... In other words, would it be best i get my i9500 back since i don't have to worry about bootloader locked and brick and all that stuff that's currently making my i337 useless.
Yes every AT&T is locked, get your i9500 back.
