I cant understand well If I can use this methid for root lollipop
I mean, can I flash a kitkat kernel only on lollipop based firmware, do the rooting with TR and then upodate the kernel to one there was before?
Or I have to downgrade the while firmware to lets say 4.4.2 ?

you must download tot rom file then flash it using flashtool
I'm a complete newb concerning flash/installing software and especially reverting back to 4.2.2.. I have the D802 International version (bought it off Amazon) its the UK edition I believe. I'm trying to find the correct firmware but they are all so cryptic I'm worried I'll download the wrong one ( I have the 32GB version) and brick my phone..
Is there any kind of reliable guide I can use to do this process? Or better yet some kind of automated piece of software?
Or would it be best to just wait for LG to release an update to fix it?
If it wasn't such a big issue ( I use my headphones every day constantly..) I would wait but I don't think I can..
Any information would help.

Hi ,
Once you upgrade your bootloader is not possible to go back to 4..2.2 (or 4.3)
You upgrade your bootloader if:
Flash a stock rom 4.3 and higher
you do not upgrade your bootloader if:
root , install custom recovery and flash a custom rom , there are a few good rom based in samsung stock 4.3 and 4.4.2 you can try them see if you like them and if you don't you can always flash stock 4.2.2 and be as you were
Ok, so essensialy i can't downgrade the bootloader to 4.2.
but a official 4.2.2 firmware (without knox) will work on a 4.4 bootloader ??? (again i don't care about knox working or not)

It has been done to 4.3 in this thread: http://forum.xda-developers.com/showthread.php?t=2744061
they have flashed a 4.3 ROM without bootloader over a 4.4 ROM so the result is a 4.3 rom with a 4.4 bootloader

HI ,
Mate if you flash with Odin or OTA (kies) you will change the bootloader , ok? so once you have a 4..4 bootloader installed there is no way to install back a 4,2,2 stock ( official ) firmware , 4.4.2 official firmware includes 4.4.2 bootloader and flashing an older bootloader than the one you have is not possible (yet)
your options are:
4.2.2 bootloader
stay there do nothing
Upgrade to official 4.4 and not be able to downgrade to 4.2.2 official
root , install CWM and install any custom rom you want ( 4.2.2 , 4.3 or 4.4.2 and 4.4.4 ) and if you do not like any of them go back to official 4.2.2
Once you upgrade to official 4.4.2 there is no way to go back to official 4.2.2 , the only way to go back to 4.2.2 would be with a custom rom

If i understood right, you are saying that can be done if i flash a custom rom as intermediate step between official 4.4 and official 4.2 ??

No . I did not say that
Once you are in an official 4.4.2 firmware , the only way to use a 4.2.2 rom would be by flashing an un official 4.2.2 custom rom

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.

Either way you're going to lose root.
Don't hold me to it, but I think if you flash Jasmine ROM version 4.0 it'll have the 5.1.1 firmware.

Hi, I meant SGH-i337 in the title.
I beleive I posted this in the completely wrong phone section last time, so I am posting this here.
My device model is the SGH-I337. I downloaded Odin version 3.12.3, downloaded the official drivers for the Samsung S4 USB, but I can't seem to find stock Lollipop 5.0.1. SamMobile only gives the 4.x versions for some reason. I started following the below link for a method to at least flash an older firmware to my phone, but I want to flash stock Lollipop. Is there even a way to get Lollipop back without root?
https://forum.xda-developers.com/galaxy-s4-att/help/guide-att-samsung-galaxy-s4-sgh-i337-t3383078
I was able to downgrade, but I still need an official stock 5.0.1 firmware. My virus protection says towelroot is a virus, so I don't want to go that route. If I do an OTA upgrade after I flash the old firmware from the above link, will it brick my phone? It's rootable NB1 ROM. I already tried to install the stock 4.x firmware from SamMobile, but that doesn't work, so it seems I need stock Lollipop.
AT&T never released a stock lollipop firmware that can be flashed with Odin. All at&t updates were released ota.

Hi I am running goldeneye custom rom on my i-337 5.0.1 with ok2 kernel. If you go to that forum thread in development, you will find very detailed instructions to get att s4 to 5.0.1 stock. As a side note I can assure you if you just download towel root on your phone, install and run there is no virus of any sort. Make sure you download from towelroot .com
On second look through I don't think there is stock 5.0.1 using safestrap....
