Good day am having problems looking for my stock firmware (taiwan 4.2.2) and how will i know if mine is a taiwan BRI or taiwan WAN. i rooted my s4 but am going to sell it so i want it to be good as new unrooted and if its posible to reset the binary. hope to here from you guys thanks a lot...

If you don't have the knox bootloader of android 4.3 you can simply unroot and get the stock firmware. But if you have knox then you're out of luck

[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You will be able to upgrade if and when a newer version of the firmware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] how to remove or downgrade CHN 5.0.1 to kitkat on I9500

Hi everyone,

Please tell me the proper steps to downgrade.

On stock rom you cant downgrade ,with flashing Lollipop the bootloader has upgradet en no way back on stock rom.

[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

I dont think you follow what I mean I dont want to downgrade from 4.4.2 per se I just want to use the other stock versions of 4.4.2 kitkat that have been released. Am I unable to downgrade from a higher version of kitkat to a lower previous version of kitkat that was avaialble a month before?
Same BTU stock version ie ugn9 down to ufn8 or something

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
