Well gentlemen since there is much discussion in this and several forums of the S4 GT-i9500 on the possibility of returning from Lollipop 5.0.1 to Kit Kat 4.4.2 after to have installed the version of 4 archives + the PIT or the version of SamMobile + PIT and that all we thought reason why it seems that it can be but that nobody has verified is that I occurred to the task of verifying if it is possible to return from Lollipop to 5.0.1 Kit kat 4.4.2 and that the S4 is working without problems and the result cannot be betteIF IT CAN AND IT WORKS EVERYTHING.-.-
Tools:
Firmware: I9500XXUGNJ1_SER
PIT: PIT Adonis
J1 Modem: Modem J1
Process :
The first thing is being in Lollipop install a custom as Recovery like TWRP or Phiilz if not installed there, immediately afterwards to enter recovery and to do all the wipes and all the formats, already we remained in this point without UNDER.
Now we reinitiated in Download Mode while in the PC we run Odín with privileges of Administrator (we do as always it) and loaded the PIT in the corresponding button and firmware downloaded of Kit Kat 4.4.2 , we connected the S4 and when it detects it to Odín we give START and we hoped to that it finishes.
When it initiates we will not see that there is no network, we have in the bar of tasks the circle with the crossed line, we will have the IMEI either or NULL, NOT TO BE HOPELESS.-
Now we put again the S4 in Download Mode while in the PC we run Odín again (as Administrator not to forget) and load modem.bin file that we will have extracted of the downloaded one and removing from the folder J1 Modem, immediately afterwards the install it and to the minute the S4 will begin and now already it will have signal of network and everything working.
NOTE: So that it is clear and they are not mistaken, the install Modem not in the same process with firmware + the PIT, because it is not going it to take, in fact firmware has the modem including but in the installtion for some reason it does not install it, for that reason soon it is necessary to only make a installation with the modem and it is put in button CP (Phone).-

And if i will not use custom recovery, if i will use only stock recovery to wipe data and only Odin for downgrading? What if i will use any stock firmware with this Adonis.pit file and modem.bin rendered herein?
I OTA to 5.0.1 recently and totally hate it. Have been googleing if I can downgrade to 4.3 but no luck. Am hopeing that someone here can help. I've got the stock firmware and odin what else do I need? Thanks in advance.

If this what you choose to call "tutorial" is the result of running a text through Google translate something must have failed in the process.
The purpose of a tutorial is usually to clear up and enlighten. Throwing out random grammar of English words is not helpful in that direction.
You don't have to perform Oxford English, but do give it second try and perhaps ask a friend speaking regular English to proof read.
Hay plz upload the video
i dnt really undrstand , pls correct this tutorial before someone mess up their phone.

Lobomarino don't seem to care much about the feedback so far. Hard to say if regular English is the right tool.

Hi, I have a problem.. If i try "Patch to Android" in menu LP wrote me "Your firmware has a jex-optimization. Firmware patch impossible. Change the firmware or upgrade to Android 5+" Am searching every where what is jex-...., but i dont find anything. I have original rom in my phone and dont want change it. Can u tell me please how can I avoid this massage and patch my phone. THX and sorry for my terrible english.
Answer from maker: your firmware have /system/framework/core.jar.jex file. It is jex optimization and lp can not patch this file. You can help only change firmware for your device.
I can't find a valid update firmware file for B360 to extract the recovery.img for Nougat. Does anyone know where I might find that? All I can find are L09 copies everywhere. I can't find any confirmation that these two recoveries are the same or different. Thanks!
I could help you with that but my "broken English" might confuse you even more. Try using the forum's search tool, you'll find many posts related to what you're looking for.

Same, I dont have issues finding combination files for my G955U ( They seem to be everywhere ) . I have issues finding the one for my Oreo firmware G955USQS3CRE2
I am going to try and flash an earlier firmware and use a combination file for that specific one.
If that's the route , which should I downgrade to? Currently at 8.0 and Which combination file would work with that specific firmware ?
I was thinking G955USQU1AQJ8 firmware and the SM-G955USQU1AQDA combination ...
Anyone have luck with that theory ? Any input ?
Will post back results .
I'm looking for a firmware (rom) for the MT6580, but unfortunately I don't know which model it is, I even opened a thread about it here https://forum.xda-developers.com/t/...s-stock-rom-or-at-least-a-custom-rom.4508783/, asking help to identify the model.
If anyone could recommend which firmware to download, at least for giving it a try. It needs to have a scatter file, by the way.
Anyone?
