I posted this in the wrong forum earlier and now I can't delete it. Sorry 'bout that mixup
I've been lurking for the past few days looking for an answer to this question, but all the I9505 vs I9505G compatibility, baseband mismatch, and bootloader update discussion makes it very confusing to jump in and know what's happening. I figure I just better ask and apologize if it's common knowledge already.
Is there/will there be a prerooted stock 4.3 zip that is flashable in CWM that I can flash on top of my I9505G 4.2.2 rooted stock ROM without wiping data? To be clear I HAVE a model I9505G and want to upgrade it from 4.2.2 to 4.3 stock while maintaining root. Normally, that's not such a big deal, but this update seems to be causing some kerfuffle/
Thanks in advance!

Hi guys. I recently flashed stock jellybean 4.3 on my S4 and am now hoping to re-root and install a new custom rom but would like a little help before I proceed.
I was using omega rom previously on 4.2 and enjoyed it so was hoping to install version 14 on my updated phone.
My problem is that I need to choose between one of the two tar files available dependant on whether I have the old bootloader XXUB or the new bootloader XXUD. Where do I find out which bootloader I have? My baseband version is i9505xxuemj7.
My second question is (sorry noobish!) can I install clockworkmod and then flash this pre-rooted rom or must I root before flashing clockworkmod and then install the rom?
If Im asking in the wrong section or am being a total noob I do apologise. I have only rooted once previously and came from years of 'ahem' apple iphone use
Any help greatly appreciated guys.
So I've been running the GE ROMs on my AT&T GS4 for quite awhile now, and have been doing fine on GE 4.3. But I wanted to try out the official Samsung 4.3 for the i337.
I've looked through the DEV section but didn't find any, so I was wondering if anyone has seen a CLEAN flashable 4.3 AT&T version that I can flash in CWM without any issues?
I prefer a clean version without any mods so I can mod it myself before flashing. I definitely do NOT want one that is going to mess with the bootloader and prevent me from flashing other ROMs if I want to go back to a GE ROM.
Thanks.
Hey guys,
Can you help out with a newbie question.
Im running android 4.4.2 on a rooted I9505 flashed with GPE edition rom. Im currently running I9505XXUEMKF baseband on a I9505 recognised as I9505G. On meteor network in Ireland.
My problem is Id like to get OTA updates, but these fail as I have TWRP installed. As I understand it this can be overcome by reflashing the stock recovery. Is this correct?
So my question then is how to know which stock recovery to flash? & can I do a backup of the current one I have installed in case something goes wrong?
Looking at this thread in development subform. & several are listed.

Hi guys, i am doing this for a friend, hes on offial 5.0.1 LP accidentally updated it and he doesnt like it.
we need to root it and then downgrade Bootloader and Modem then flash a Stock based ROM yes !?
i have fetched latest KK modem/BL from a thread on xda , one with WiFi fix supposedly.. and the latest KK BL as well.
but i cant find a Flashable Stock KitKat Rom anywhere.. can someone help me with this please !?
and maybe link me to the stock Modem/BL as well.. cause i dont wanna brick his phone.
for now i have only Rooted it with AutoRoot.
You don't need to root it in order to be able to downgrade. You might even trip Knox in the process, so you're on the safer side if you don't do that. But as you have probably already done that, you could back EFS up using EFS Professional or terminal, just in case it gets corrupted during flashing.
I'm not completely sure about the downgrade process and what it takes not to brick your I9505, but you can find stock KitKat firmwares (flashable in Odin) here and here. There are some stock KitKat firmwares here as well, but some of them are offline. You can find some firmwares at SamMobile too, but you will probably need to pay to download from there.
Some pre-Lollipop modems can be found here, some more modems and bootloaders here.

Greetings. Here's a bit of quick backstory-
I have experience rooting many android devices. I have only flashed 2 kernels before iirc (2 different devices) with Odin. I've tried to do as much reading as I could but I'm a little stumped and also been having some brainfog due to life stress so I need a little help if anyone could be kind enough to help.
The main device in question is my At&t Galaxy s4
-SGH-1337 on 4.4.4
-Baseband/build NJ4
-Stock at&t rom as far as I remember
-Rooted
-Locked bootloader
Now what I want to do is flash a good custom rom. I have my eye on Hyperdrive but I'm confused on a few things-
•Do I need to use loki or safestrap? Which one should I use?
•To use Hyperdrive RSL20 do I need to downgrade from 4.4.4 to 4.4.2? Can I even?
•If Hyperdrive isn't an option for me, how exactly should I go about flashing something like Goldeneye? I'm a little confused on the process at this point with both loki and safestrap. I tried the newest version of safestrap for NJ4 apparently but the rom slots apparently aren't working yet for that version and I wasn't sure if it was wise to flash over the stock rom slot. Kind of confused on this whole thing.
I'm not asking for fleshed out guides or anything as I can find those myself. Just kind of need some clarification on these things for the tl;dr version-
•Being on 4.4.4 locked bootloader, if I want to flash a 4.4.2 rom, do I need to downgrade? Can I even?
•Should I use loki or safestrap? In order to use safestrap in my case it looks like I"ll have to downgrade either way, is this correct?
I thank everyone for taking their time to read through this.
Also mods, I apologize if this is in the wrong area.
Read the first few posts of http://forum.xda-developers.com/showthread.php?t=2616221. That should give a lot of valuable info.

I'm still unclear on a few things I guess.
I've read that thread over and over before it was linked, and read it a few times again.
I realize being on NJ4 that if I use safestrap, I have to flash the stock rom slot and it must be a touchwiz rom. Got that. What I really want to know at this point is that are 4.4.2 and 4.4.4 roms interchangable? For instance- I'm on 4.4.4 nj4. Can I flash hyperdrive which is a 4.4.2 rom?
If not and I have to downgrade, is it even possible for me to downgrade being on a locked bootloader?
Edit: Well I just bit the bullet and downgraded to 4.4.2 via odin, did full wipe with safestrap etc, and got the hyperdrive rom up and running. A little disappointed as I was hoping to get a better antutu score but it was the same score I got with stock nj4 rom that I debloated myself. Meh. I guess I might give goldeneye a shot.
Bump! I'm in the same situation
After playing around with all that Hyperdrive rom had to offer as well as ktoonz kernel and overclocked profiles, I made the jump to a custom Lollipop rom ultimately for the performance upgrade of Lollipop's ART system. After seeing the difference I really see no reason to go back to kitkat at this point. I've been using the 5.0.1 Goldeneye rom and like it so far. I just have a few kinks to work out but overall it's been good. I'd like to get a 5.1.1 rom on this but alas I don't think I've come across a safestrap compatible one yet.
