Didn't find the similar question here. hope anyone can help to answer.
the bootloader is unlocked and system is jb 4.1.2. I want to update to kitkat and keep unlocked BL.
I have downloaded the rom VZW_XT907_4.4.2-KDA20.62-10.1_CFC_1FF.xml.zip
is rsd flash ok, or is there a fastboot way to update anything like system, radio, recovery except BL to kitkat?

Update everything. Once unlocked, your bootloader can't be locked, so you are safe. I recommand you not to try to flash only some parts. It should cause hard brick (something similar happened to me).

I have a unique situation. I have a I337 with KangKat installed and TWRP recovery installed. I just received an unlock code for my device, but it does not accept the code. I have been told that since the phone is rooted and running a custom rom that the code does not work. My question is can I download a stock rom. Install it using TWRP. type in my unlock code. get the device unlock. Can I then install KangKat again? Or will installing the stock rom messup my bootloader and I will forever not be-able to load a custom rom again?
I would greatly appreciate the communities expert advice. I do not want to lose my ability to install a custom rom but I need to have my device unlocked for international travel. Thank you.

Since you have TWRP installed, you are either on the MDB or MDL bootloader. Flash the stock firmware matching the version, using Odin. Sim unlock and then you can reinstall TWRP and your custom rom.
Run the follow commands in a terminal emulator (app) session or adb shell
su
getprop ro.bootloader

I fear using Odin. Horrible stories from the time I flash a Tab 1. Is this the only way?
Does anyone know if I recover to a stock rooted 4.4.2 rom will my unlock code work? or will it not work because its rooted?
Do not go to 4.4.2 as it has a locked boatloader and no direct root method.
I use odin on a daily basis and I haven't seen any issues. I haven't heard of anyone reporting any issues due to odin on this phone in this forum.

Ok i just downloaded the stock rom I337UCUAMDB_I337ATTAMDB_ATT. Does anyone have a link to the MDL rom?
I've been told to start with the oldest rom and work my way up till it doesn't fail the odin flash. What is the order of roms I should try?

Sammobile has a link to MDL.
The newer bootloaders prevent a downgrade of bootloader. That is the reason you have been asked to try from older to latest one that works. You need to do that only if you dont know the current bootlaoder version. I already gave you the method to find the current version on your phone.
MDB->MDL->MF3->MK2->NB1
From MF3 onwards, custom recoveries like TWRP/CWM will not work. The only working recovery is safestrap. You will also lose the ability to flash AOSP ROMS.
Wishing that it works with MDL stock itself.
All about MK2 and NB1
Got my unlock code working!!!
First off. I want to thank the XDA community with their knowledge. The quick responses to my post is much appreciated.
I was able to get my unlock code working without having to use Odin. Thanks to an internet buddy who put me on the right track. Since I have TWRP installed I was able to install a stock 4.4.2 Root AT&T rom. I then put my unlock code in. And BAM Worked!!! I then restored from my original backup and now i'm back to running KangKat.
Thanks all again!!!

And thanks for reminding me that with a custom recovery you can flash almost any rom. I had lost this ability long back when I moved to S4 and got a phone with MF3 on which custom recovery doesnt work. We can do only restricted stuff with the safestrap recovery.
Hello,
I'm on one of the old crash lollipop roms with a kitkat bootloader, baseband, etc. How do I change modem and bootloader to lollipop?
Thanks
you just can't. nobody has ever done it before. maybe in a year or so...

Go to sammobile.com and download the latest firmware for your phone. Use Odin to flash it.
If you are rooted and have custom recovery like TWRP - do a nandroid first than once the stock has completed you can re-root, flash the custom recovery again and then restore system and data from the nandroid and you should be back to normal but with updated BL and modem.
I've gotten no help at all with this. Very unlike this forum. My phone is a kltevew, which is straight talks version of a g900v. I need help, there are lots of great looking Roms that require you to have mm firmware I'd like to try!
Not sure why I'm getting g no responses on this. Surely someone must know something... The only response I got was not only not helpful but jerky and obnoxious. Doesn't anyone know how to upgrade the firmware on my phone? (And no, google has no answers for me on this.. I look everyday)

Download it with samfirm http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647 (Model= SM-G900V Region= VZW) or from sammobile http://www.sammobile.com/firmwares/database/SM-G900V/ , do you know how to flash firmware with odin?
I do. Thanks so much for responding. Every time I try with Odin, a few different releases, it always gives me the error message fail. Can it be done with flashfire?
What stands in the log of odin when the flash completes?
Ill have to do it again to see... Be back in a bit!
I think it says FAIL! modem but I'll have to run it again... Brb
Last night I used flash fire to install firmware. That didn't get past the red Verizon logo, so I put twrp on it with Odin. Twrp showed it as dpd1, but it just wouldn't boot. So I wiped it once and flashed a ROM that requires mm firmware. Same thing, justbootloop. So I put stock back on it, then mokee 6.0.1. which works, I'm just not on mm firmware and all the great new roms are still unavailable to me.

Have you enabled the option to flash bootloader on flashfire setting?
What? No, I haven't... but do do right now. Thanks for the tip! Actually, where would I find it?
So would I do it in this order? Flash the dpd1 bootloader, then modem, them rom, then jrkruse patch? All in flash fire?

It's in setting of flashfire...but only do it if odin doesn't work because do it from flashfire is more riskiy...
1)do a backup
2)check the bootloader flash option
3)install the firmware with all the wipe except internal storage(it mean that flashfire delete /data excluding /data/media/0 (sdcard) but include it in your backup copy because you never know )
4)wait till reboot skip setup wizard "spamming" the next button then install the rom with flashfire or twrp
On the flashfire site i found this:
Flash bootloaders
"This setting controls if FlashFire will attempt to flash bootloader partitions. By default, bootloader partitions are only read and never written. Even when enabled, flashing bootloader partitions may not succeed - many devices have protections in place against the bootloaders being overwritten.
Please note that flashing bootloaders is extremely dangerous. Any bug, error, or failure may result in an unrecoverable hard-brick. Do not use this feature unless you know exactly what you are doing.
Due to the danger of this feature, it is automatically turned off every time FlashFire starts. You have to manually re-enable it every time you want to use it.
If you must flash bootloaders, it is advised to use a bootloader-based flashing tool such as fastboot or ODIN to do it, as these are the safest methods. OTAs may also update bootloaders, and though slightly less safe than fastboot/ODIN, it is still much safer than having FlashFire flash bootloader partitions directly."
So i suggest to try to flash the firmware directly from odin first
No dice... still doesn't boot up past the red Verizon logo

did you install the firmware in the "AP" box on odin? (after you factory reset your phone)
I did. At this point guess I'm lucky I haven't bricked my phone. Ive tried every possible combination, nothing works!

Redownload the firmware extract it again,factory reset your phone,and try to install the firmware,maybe it's a bad download
Should I be flashing a kernel too? Will it even start/boot without the right kernel?
find out if you phone is refurbished. to install stock ROM you would need the main board and boot to be the same model.
if it's not, then you just need to install bootloader/modem without full ROM. look around in xda for bootloader/modem.
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.
So I have been having a really hard time trying to get TWRP installed. And now I understand why, it's because it's AT&T and it has a locked bootloader. But being the stupid me I sometimes am, I installed it with Flashify. It succesfully installed! But oh wait.... The bootloader is LOCKED and now whenever I try to boot into recovery I just get this message 'System software not authorized by AT&T has been found on your phone.' And I don't know how to fix this. I just really want a custom recovery so I can install customs ROMs. Thanks for any help in advance

Well, first I think you may need to flash a stock ROM to get rid of that message.
Next, the custom recovery you are looking for is called SafeTrap. Similar to TWRP, but it should work with locked bootloaders.

But I am running Android Lollipop, will SafeTrap work? Do I still need to flash a stock ROM? And If I need to, should I use Odin to do it?

The only way to flash stock is with Odin. Or Kies.
I don't know if it will work on lollipop, due to the bootloader being locked tighter.
But if it doesn't work, then nothing will.

If your phone is AT&T S4 (SGH-i337), the highest firmware available is NB1 firmware cooked by muniz_ri . You can get it from here.
You can flash that with odin. Once you are in NB1 you can root the phone and upgrade back to lollipop. You can read the instructions and get the required files here.
As SGH-i337 has locked bootloader the available custom rom flashers are safestrap and flashfire. Using safestrap in lollipop is pain in the neck so I use the flashfire.
You are also in the wrong form IMHO. There is a separate forum for SGH i-337. You can find it here.
The i337 cannot accept a custom recovery other than safestrap and custom roms must be based on a stock s4 rom which means no cm or aosp.
