Downgrading 4.4 to 4.2 or 4.3 on I9505? - Galaxy S 4 Q&A, Help & Troubleshooting

I'm already aware of the Knox bootloader stuff, but with the S4 Mini there's a baseband version of the firmware that runs 4.2, but has a Kitkat bootloader. I was able to thus successfully downgrade my S4 mini from Kitkat to Jelly Bean.
That said, is anyone aware of something similar for the S4? A regional version of the ROM with Jelly Bean, but the KitKat bootloader?

[Q] downgrade from 4.4.2 to 4.3 sm-n900w8

hi guys
i was wondering if anyone can help with downgrading from 4.4.2 kit kat to 4.3 jelly bean on my Canadian SM-N900W8 with Rogers.
I accidentally upgraded and want to return to the pervious 4.3. Ive researched a long time and ive read that once you upgrade you cannot downgrade back to jelly bean. Ive also read another post on here that said with Canadian Sm-N900W8 if you download the Mexican 4.4.2 and flash it via odin that you can return to 4.3. Can anyone confirm this and provide me instructions.
Ive downloaded the PIT, BL, and AP for the mexican 4.4.2 and it says to use the CSC AND modem from the stock rogers 4.3.... i have the N900W8VLUCNB7_N900W8OYACNB7_RWC.zip but i dont how how to use the csc and modem from it?
Any help with returning me to 4.3 would be appreciated.

Sorry to say but you cannot downgrade from 4.4.2 to 4.3 rom/firmware.
You will be able to upgrade if and when a newer version of the firmware
is released.
Good luck!
If you upgraded to the Mexican 4.4.2 from 4.3 then you can downgrade back to 4.3. But since you upgraded to the newly released NB7 I believe you're stuck there as Samsung patched the bootloader already for the N900W8.

[Q] SM-9005 What is the final version of [4.3] Jelly Bean and where can I get it?

German unbranded unlocked Note 3 SM-N9005 currently on 4.3 build UBMJ3, baseband N9005XXUBMJ2, I want to stay on Jelly Bean because I don't need any bull**** and drama with Kitkat or Lollipop but I want to update to the latest (final?) build of Jelly Bean before I root. Can anyone point me to the highest official build of Jelly Bean for my phone? Also is rooting with Towelroot the best option if I want to install Xposed?

The above thread gives information on how to downgrade to KitKat (Android 4.4.X) from Lolipop. However, how would someone downgrade to Jelly Bean (Android 4.3.X)?

[Q] 4.4.2 bootloader which stock 4.4.2 firmwares can i downgrade to?

Sorry for the newbie question i am using samsung s4 from o2 uk and have their 4.4.2 version, i am unlocked now so can downgrade or upgrade to BTU unbranded 4.4.2 versions of which there appears to be 4 available in sammobile.
I understand that there is a new bootloader in 4.4.2 so am i able to upgrade /downgrade to any of the stock 4.4.2 firmwares without tripping knox or losing my imei?
I know to my annoyance that the new bootloader efs v2 in 4.1.2 xxemg4 for the samsung s3 prevented me to downgrade to any of the previous 4.1.2 stock roms due to this much to my annoyance as the battery life was superb on xxemc2 4.1.2 so i don't want to make the same mistake with 4.4.2, does anyonr know if there is another bootloader version in the latest 4.4.2 stock rom that may cause a similar issue?
Bear in mind i only want to be able to up down grade to any of the 4.4.2 that is available not go to 4.3 or up to 5.0 as far as you're aware are all versions of 4.4.2 BTU ok to flash in odin without issues?
no downgrade from kitkat

Yes as long as you are downloading the correct firmware for your phone based on model number you will be able to downgrade. Just use Odin and you should be set.
You can flash any 4.4.2. The different versions don't matter.
Are you 100% sure i can up or downgrade to any of the 4.4.2 versions?
I dont want to make a mistake like i did with my s3 whereby i updated to 4.1.2 xxemg4 the latest version of 4.1.2 available but had an efs v2 so was unable to downgrade to any of the 4.1.2 versions below it.
4.4.2 kikat has a new bootloader but they all have the same efs version right? Thanks for the help

Is there anyways to unlock bootloader of shv-e330s?

I want to downgrade to 4.2.2 but I can't find the PDA in my phone only the 4.4.2 has the exact PDA in my phone, I was downloading some stock firmware on sammobile and Samsung updates but still only 4.4.2 has exact to my phone and there is no 4.2.2 available for my phone, so I've read some forums that GT i9506 is bootloader unlocked and the i9506 and I've heard some people that shv -e330s is same with i9506. And other variants of s4 is bootloader locked. So is it possible that I can downgrade 4.2.2 from 4.4.2? My s4 is shv-e330s
This was my phone firmware:
