Yes, a USB jig will work to put the phone into download/odin mode. You can't use LOKI or Clockwork mod recovery on the at&t galaxy s4 unless you are on the MDL bootloader running Android jelly bean 4.2.2, and no you cannot downgrade if you are on kitkat. You can't unlock the bootloader either as at&t has it locked up tight. If you are on kitkat, then you must use safe strap for ROMs.

I just followed this thread and successfully rooted my S4

I think i deleted some core apps thru titanium backup and the phone could not display normally (keep Blinking)
then I tried to downloaded Goo Manager and installed TWRP Recovery on my S4. when I restart my phone can only boot to ODIN mode. I fixed this by using

Now the phone can boot up but stuck at ATT logo Screen. Any body can help me?
PS. I try KIES emergency recovery and it keep telling me there is a error of updating.
I bricked my s4 (i337 Canadian, bell) the day I bought it, TWRP 2.6.0.0 was what bricked my phone (I think, or improper use of TWRP) and it wouldn't boot whatsoever (even my recovery was bricked), I managed to fix it by flashing stock firmware from ODIN 1.85 on PC to the phone (couldn't access recovery, so I flashed from PC) , make sure you download a stock firmware that is .tar to use with the PC version of ODIN, the second thing I had to do was flash CF Auto Root again using ODIN 1.85 from PC to phone, since I still couldn't boot my phone or recovery (other root flashing methods wouldn't unbrick my phone, but CF Auto Root did, download the MF3 version of CF auto root).
after all this crap I installed TWRP 2.5.0.0 as my recovery and haven't had any issues since :victory:
this was done on a I337MVLUAMG1 which I believe is the bell equivalent of the MF3 (update that blocked rooting by most methods like motochopper ect)
Thanks

Dont thinknthere is antthing you can do. We have no return to stock method at this point in time. This is why it is important to follow forum rules and read and search before doing something youll regret, im nkt saying this to be mean...but there has been at least 5 people these past few days who have done the exact same thing as you and have gone in here looking for help...
My best advice, throw in some money for the bootloader unlock bounty and hope somethung happens soomer than later

If you read through the threads it specifically stated that the MF3 boot loader is locked and you cannot install twrp or custom ROMS on it. I have seen so many posts regarding this it makes me sick. It's kies seeing the device? But is falling to recover? Or is it not seeing it?

the Kies can detect the phone buy it fail to recover it. the progress bar runs a little and stopped. error message pop out on PC screen says "Emergency recovery failed, Please contact Samsung Customer Service"
I am on MK2 4.3 and I have Safestrap installed and I installed the recovery and when I reboot into recovery It goes to the Custom screen then it fails to Go to the Splash screen where I can choose to go into TWRP . I had this working on MF3 but I had bricked my phone and and had to flash the allin one to fix it . I am successfully rooted with safestrap installed .. ANY IDEAS would be greatly appreciated...Thanks By the way it Says Safe system : Not Active. I thought I remember it saying Active before
Also is there another way to install a Recovery. Im coming from a Tmobile GS2 where you could flash recovery once within Odin and after that you could just flash different versions of Twrp or Cwm when needed. No locked boot loader . I always thought HTC was the only phones with locked boot loaders . I have been doing a lot of reading prior to posting this question and have been up all night . After bricking last night and recovering from it I got a crash course with this device.

Check your root condition is valid. If you do not have root you can not install the safestrap recovery.
To go to the safestrap you do not need to reboot into the recovery. You simply reboot as normal and safestrap splash screen would come up.
You can use odin to flash the recovery in the download mode or you can use adb command to push the recovery.
AT&T and verizon G4 bootloaders are locked. You can not unlock like HTC S-off. You can only exploit the bootloader with different methods based on your firmware version.
Simply reboot the phone and on boot up it will show you the splash screen. Not active means that stock slot is still selected.

So I was able to root for the first time with Towelroot. That was successful and the I downloaded the clockwork mod and rom manager to attempt to flash Cyanogenmod. however after installing those two apps I restarted and when it booted up it now only shows the error message "System software not authorized by Verizon Wireless has been found on your phone. Please turn off your phone and go to the nearest Verizon Wireless store for help. I do believe that I created a backup on my SD card but I cannot access it and I cant seem to be able to even use Odin to get my phone back to stock Kit Kat firmware. Can somebody please help figure out how to get my phone to boot back up and hopefully keep my root intact?
If your on a retail note, you can't run cm so you would need to Odin back to stock nc4 and re root with towel root and install safe strap recovery . If on developer note 3 dis regard and wait for someone with a dev phone to answer.?
thanks
Okay thanks but wouldn't that just put me back into a bootloop again? using safestrap and towelroot put me in this situation and I don't know what caused this issue and I would like to avoid it at all if possible on my next attempt. Is it because I didn't unlock the bootloader?

You can't unlock the bootloader on a retail Note 3.
Towelroot and Safe strap didn't get you in this situation.
You need to do a bit more research and read up before continuing.
All we have is root.
Safe strap is needed to run custom roms.
There are no custom kernels available since the bootloaders locked.
So don't try to use cwm.
Try to get your phone in download mode and odin the stock tar then root again and install Safstrap 3.75 build 4.
Yet another post... So, I have been trying to install TWRP and CWM but every time I boot into recovery with those installed I get: "System Software not Authorized" error. Is there anyway to bypass this? I think I Soft Bricked it, but I fixed it with Odin and a stock recovery file. I just want to get a custom recovery... Any help is appreciated.

Can't install cwm or twrp on an s4 with a locked bootloader.
Hmm that is strange.

How would I go about unlocking it? I remember before the s4 got the 5.0.1 update and I had cwm.
The att s4 bootloader can't be unlocked once it has been upgraded to a locked bootloader.
That sucks. Is there another phone that can unlock it's boot loader? I head something about asking the company to unlock it for you. Is that possible?
Quick little update:
I have found some options that might work. Option 1: Someone said that you could downgrade to 4.2.2 because that has an unlocked boot loader. Or option 2, which is go to Best Buy and tell the Samsung Support Center dude to unlock it for you. I really would rather go with option one, because what if the dude denies it. Unless, because I already got the locked one on my device, there is no way to downgrade it...
There is no way to downgrade the bootloader to 4.2.2 or to unlock the bootloader.
Right, well I installed Safestrap and updated to 5.0.1 with keep root method. Something I just realized is that we have a s2 laying around somewhere. I guess I can mess with that. And as for a new phone, I guess I will save up to buy a Nexus 6 from the Google site.
Lately, I wanted to root my GS4 (it surely wasn't an AT&T one, bought it in Russia, there is no AT&T). So, motochopper fails, CF-Auto-Root fails, everything fails! I am stuck at 4.4.2 and there is no OTA upgrade. Download mode says "MODEL NUMBER: SGH-I337", but in the "About phone" menu it is clearly stated that model number is "GT-I9500" and build number is "KOT49H.I9500XXUFNB7". Even the baseband version starts with "I9500". All the hacks I am seeing on the Internet (such as Loki) for unlocking bootloader fail, saying that my phone model is not supported. Heimdall and Odin fail to flash anything and the red text appears in the download mode: "SECURE MAGICODE CHECK FAIL". What my model is and what do I DO? I want to root it and install some decent recovery and CWM ROM.
Please, ask any questions you like and help me)
The model number in download mode is the right one. Once the bootloader on the i337 is locked, it cannot be unlocked.
A locked bootloader means cwm and twrp cannot be installed.

Why can't it be unlocked? I've seen so many guides and tools to do it. The problem is that they don't work and I don't even know my true build version to figure smth out. Why doesn't it even root like normal I337 should do? Also it doensn't upgrade to lollipop like normal I337 should.
The bootloader is locked on the i337, just like it is on other at&t phones, with no way to unlock it. An s4 bounty on XDA for finding an unlock method remains unclaimed: http://forum.xda-developers.com/showthread.php?t=2257620
The phone is an i337 and can only run stock i337 roms or customs based off a stock rom.
Safe strap is the only custom recovery available for a locked bootloader.

So, ok. We managed to confirm it is a SGH-I337. But what about Loki tool? It can install CWM recovery, but does not work on my device? Also, I ask one more time, how can I know what the real build number is? And how to root? All SGH-I337 should root with motochopper but mine doesn't. What can I do about this?
Cwm and twrp cannot work on the phone. I have never seen a post where someone has ever had it work with a locked bootloader.
I'm not sure but motochopper may not work with every bootloader and every rom. Reading through this forum, I don't think I remember seeing motochopper mentioned.
You'll have to confirm the bootloader and rom in the phone and search through the various rooting threads. I don't have access to the i337, only the i337m as I am in Canada.
