I hit on UPDATE on the phone for an OTA update but it only says UNABLE TO CONNECT AT&T SERVER. When I bought it, it had 5.0.1 (I337UCUGOC3) out of the box. Searching on internet says that is bootloader locked (so I cant do anything).
- Can I Update to I337UCUGOK2 and bootloader will be unlocked (I mean, will I be able to do it)?
- Does anyone know where can I grab I337UCUGOK2 for offline install and is it ODIN safe to update it (remember I have I337UCUGOC3 bootloader locked)?
please help
Once the bootloader is locked, it will always be locked until someone finds a way to unlock it. Updating the bootloader will not allow it to be unlocked.

Unlocking/exploiting the bootloader for the AT&T is still in process, I think.
Bootloader locked means you can not install custom recovery like TWRP, CWM or custom kernel. You can still root, you can still use odin and you can still install custom rom using either safestrp or flashfire.
Here is the thread explaining how to upgrade stock or rooted stock roms.
The explanation starts from installation of NB1 firmware so that you can easily root the phone by using twolroot.
If you do not care for the root you can start reading from the step 2 "Flash update in stock recovery"
Since you are on OC3, you need OC3 to OC4 and OC4 to OK2 files to get OK2.

Everywhere says I need a kitkat rom as base.
My s4 came with 5.0.1 with OC3 and bootloader locked out of the box. I tried some post where says I can flash TWRP and CWM but my phone stucked on bootloops. Then I managed to get back to stock rom and now when I want to turn it on it says " SAMSUNG (and lower on the screen) Custom"
Camera began to fail and I want to return it as RMA but I was looking to reset the flash counter but every post I read is that OC3 bootloader locked users are just doomed.
Do you know a method that I can do for reset that counter?
Camera dont focus anymore and I tried all the posts about safemode, etc.

Flashing TWRP and CWM is for the AT&T S4 with older bootloader (MDL, MDB). After that two firmware versions the bootloader is locked.
For AT&T S4 the last full firmware released is NB1. After that they released incremental updates via OTA. That is why you need kitkat (NB1) as base.
For NB1, Muniz uploaded two firmwares. One is the stock and the other is rootable stock. Try the stock one and see you still have the custom symbol.
To reset the counter, there is an app calls Triangle away by Chainfire. However, it does not work on AT&T S4 with locked bootloader.

Thanks. I'll try Odin it with the stock rom from your link. I'll post news here when it finish flashing
1st part - Success
I'm on 4.4.2 NB1, flash counter back to normal but still bootloader locked
Now I have to go back to OC3 to RMA it.
OTA does nothing, smartswitch shows no updates neither kies.
I'll have to Odin it back to OC3
Can I have some help?
And Success. I'm back on stock OC3 no root.
time to RMA
- camera still doesn't focus
- boot screen is back to normal but when in odin mode the counter shows 0x1
- sometimes shows "sim card could not be detected" or similar messages and force me to restart the phone (just happend 2 times until now, never happend before)
I followed this thread

I have the sprint gs4 and its at MK2 and 4.3. I am wondering if I can sim unlock this phone without calling the carrier for domestic use? I called the carrier first to ask for a sim unlock and because the previous owner was late on his bill payment twice last year they say the account isn't in good standing and refuse to unlock it. So I rooted my phone and lost my wifi and mobile network, got that fixed and decided to go to sprint and add the phone to my account and learned my phone was freezing on the dial screen and no sound, so I followed Spiricore’s Extra Safe Root-To-ROM Guide to resolve the issues and that is where I stand now.
Can someone please point me in the right direction if this phone is able to be sim unlocked without having the carrier do it?

If you are on 4.3 with the Knox bootloader you can't do what you're asking as far as I know. You'd need to go back to MDC or MDL, and you can't if your on MJA/MK2.
If you're not on the Knox bootloader there are instructions in these forums for domestic sim unlock. THIS QUESTION IS ASKED EVERY. " DAY - CAN I SIM UNLOCK, HOW TO SIM UNLOCK, DOMESTIC SIM UNLOCK" ETC..
Maybe you'll get lucky and get it going.
oh yes you can
you only trip the knox counter but i install any rom i want all the time
wont be under warranty but who cares as you can pretty much flash what you want
you can even get back to stock official mk2 but knox warranty bit will = 0x1 which means something been modified but thats all
just run triangle away and reset counter to 0 (follow its direcections) then after its done let it reboot then power off phone
put phone in dload mode and flash official mja and let it OTA to MK2
works for me to get back to stock
i use philz cwmr for my recovery and i install supersu1.86.zip but make sure after you boot into philz cust recovery tell it to reboot to bootloader one time and select NO to fix root
after it boots back into the recovery flash supersu1.86.zip and bam your rooted with a custom recovery
from this point you can install just about any rom i believe

There currently isn't a way to reset the knox warranty flag. If you've done it than show some pictures. Triangle away resets the load counter but not the warranty flag. So it's kind of useless until there is a method to reset the knox warranty flag.
But that said, while you cannot currently downgrade fully to MDC because of the knox enabled bootloader in MJA and newer. I believe all you have to do is downgrade to the MDC modem to attempt the unlock process. If you search the unlock threads I believe people have been successful. After you complete the unlock then you can flash your modem back to MJA or MK2.
sim unlock even possible?
Hello,
I wonder if it is possible to unlock the sim of a sprint galaxy sph-L720 with mk2 baseband and android 4.3.?
What steps do I follow to unlock sim without being root?
you need to root first and change the rom? could you recommend some procedure.
I can return to the mk2 mdc or not as the official 4.2.2 and mdc?
sorry, use a translator to ask my question.
I hope you can help me.
Thank you for your attention.

The OP was asking if MK2 can do the SIM unlock and the first response was correct. All the info on here regarding doing the unlock require the phone to be reverted back to pre-mf9 firmware. MDL usually. Once someone takes the MJA or MK2 bootloader they are stuck and can not go back. Everything you said about rooting and flashing on MK2 is correct, just not relevant to the original question.

i never said one time triangle away resets knox counter
i clearly said it will void the warranty
i said you can go back to stock
go in settings about phone and it will say official in both areas where you check
you can then take any OTA update just fine
so yes you are stock exactly like i said
i clearly said warranty will be bad but who cares.
people getting drunk and on the forums again....
I don't know about MkII but I took the 4.3mja OTA and that was before I had attempted any rooting or anything like that. So I started from there. I did root 4.3 and then ran Sacs but wasn't able to find any way to unlock until I found this info below:
I was able via odin to flash the phone and modem from the files in http://forum.xda-developers.com/showpost.php?p=49209582&postcount=695
and then find the file for MDC modem flash (that file is on first page of international unlock thread).
I first followed the international unlock guide, then the domestic unlock guide and I was able to unlock my phone. It was working fine on at&t until I re-rooted and now I'm not getting data.
Now, I saw the little knox message at the top of the screen on boot after rooting the first time, but when I flashed the stock tar from the post above it doesn't show up anymore, for whatever it's worth.
Right now I'm on the 4.3 from above with an MDC baseband.
Help please with SPH-L720

Please can anyone tell me the reason why I cannot flash anything via odin... I'm trying flash stock Rom MJA baseband over MK2, but everytime i click start, odin take about 10 seconds after it fails, the same error while trying to flash MCD, MDL, and when trying to downgrade only the MK2 Baseband to MDC

Because you CANNOT downgrade via odin anymore thanks to Knox. You can't go from NAE to MK2 or MK2 to MJA. MODEMS are fine but full tars are not.

Is that mean my SPH-L720 cannot be unlocked? Or is it impossible to get this phone unlocked if someone already upgrade to MK2
I know this is counter intuitive to most people, they usually want to stick with the older bootloader without that KNOX crap.
I want the newest bootloader so I can run the current kernel for 4.4.2, right now my phone is stuck on the MG1 bootloader, which can't run the kernel for this version and I don't have WIFI.
I tried flashing numerous times with ODIN for factory firmware from sammobile. I have an I337M from Canada (Rogers/Bell/Telus)
I can't get OTA to get working again because it thinks I'm on modified system etc, bootloader, even I reflashed everything...
Have you tried a data factory reset from within stock recovery?

Remember your on a I337M, your bootloader is unlocked. Do NOT flash any US-based AT&T firmwares or your end up with a normal locked I337. What version are you trying to flash in Odin? Flashing the MG1 firmware should work, what errors is Odin producing?
As the Title states I have been trying to flash to Lollipop using the thread Update to lollipop and keep root using Flashfire app. I have downloaded and followed the procedure (yes I am rooted and confirmed with RootBasic) with it failing.
What happens is I load the files in order stated per the guide hit the lightning bolt, does the reboot and then gives error no command and then sits at stock flash update where you can either reboot, flash file or few other choices. I have tried numerous times with each time same result. What is going wrong? As I stated on am on MK2 firmware with ATT update frozen so not sure why this is. When put in download mode I confirm Knox 0 and Offical software with it having 0x30 for bootloader. Any suggestions or should I ODIN update but with what?

We just discovered this morning on the Vz S4 that FF does not function properly on their MK2(4.2) firmware which is likely also the issue here. You will first need to update to KitKat using the following file then root with towel root before updating to 5.0: https://www.androidfilehost.com/?fid=23501681358548937
Before I proceed to KitKat with file linked to is there a guide to properly performing this and then rooting? I will update from MK2 to NB 1 then I need to root, then do the FlashFire and Lollipop undate. I see the guide to use ODIN but then I will have to root I also have not used towel root either so any guide would be awesome. This should not change KNOX either correct (although I guess it does not matter since I am long out of warranty)?
I want to have a clear understanding of procedure so I don't brick the phone! I have not used ODIN before since I haven't really done much rooting other than when I first got the replacement phone last year
I'd suggest [GUIDE]Odin to Stock, Updating, Rooting, and Installing Safestrap by guut13, and of course [How-To] Update to I337_OC3 - 5.0.1 and KeepRoot (4/7/2015) by muniz_ri for rooted Lollipop. Look in the I337 General forum for both.
Thanks Creepyncrawly and muniz_ri for both of your help it was easy to update from MK2 for this noob!
Ok I followed the guide and did update to stock nb1 and rooted, used towel root and then used flashfire to Lollipop and all seems to be working (I still am in process of setting phone up but it is running lollipop).
Since this is oc3 rooted is there anything else I have to do such as freeze att update? Anything else I should do right away?
So I need help. I tried to downgrade from lollipop oe1 to kitkat nk2 but every time I try to flash the firmware with Odin it says failed and my phone says fusion 2 < binary 1. Any way to fix this?
Edit: ok so after doing some research I found out verizon chose to mega lock bootloader with the oe1 update and you have no choice wether to take the update or not, but anyway the update madness it so you cannot downgrade or root.
So I was wondering if I can just flash the od5 bootloader in Odin and that would just just allow me to downgrade? Idk
Nope you are locked out un-rootable. You may very well brick your phone even trying.
Okay, here is the deal. I was trying to install a costum rom on my att galaxy s4. What I did was I rooted it using king root and tried to flash a rom through rom toolbox, but I believe it was just going to take me to my recovery. After that the screen got stuck on the costum screen with the padlock, and only seems to turn on with a charger plugged into it. I am on 5.0.1 lollipop and have managed to flash the original recovery, but any stock rom I try to flash using Odin fails by saying complete thread failed or something like that, and says on my phone binary 1 or something like that. I really need help on where to start.
Thanks
What is the exact Odin error?
AT&T never released a full firmware for flashing via Odin beyond 4.1.2. Look here for a possible solution: https://forum.xda-developers.com/ga...-to-update-to-i337oc3-5-0-1-keeproot-t3075814
Once the phone is running a 4.3 or higher bootloader, the bootloader is locked and custom ROMs can't be installed unless the custom ROM is based on a stock ROM.
There's an ODIN flashable Android 4.2.2 MDL bootloader tar file out there somewhere too.
If the bootloader is locked, and it sounds like it is since it's running 5.01, Odin will not be able to flash a 4.2.2 ROM or bootloader.

1. The above process will not affect your Knox Warranty Flag.
2. The process will update your Modem, Non-hlos, System, Kernel, and Stock Recovery.
3. No need to wipe prior to flashing! The ROM will automatically perform a factory data reset.
4. If you are not already rooted (or to unbrick) you must first flash the I337UCUFNB1_Rootable_Full_Odin.tar (use Odin's PDA slot (AP in Odin v3.09+), root with Towelroot, then proceed with the above process.
