Changing the CSC avoid the warrenty?

Hi guys,
after flashing the GE and the CM I'mthinking to flash back to the last 4.3 stock that is rolling out...
I think I'll do it with ODIN, and I'll get the terrible knox, right?
I'm thinking also to change my actual CSC from XXU to ITV since I live in Italy but... does this mean that my warrenty will be invalidated?
Does the sn or something else is associted to the original CSC and then in the repair center somen can understand that I've chenged the CSC?
Thanks!

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

How to update to Lollipop and root

Hi, I just got my new S5 model number: SM-G900F with android 4.4.2 with the build KOT49H.G900FXXU1ANG9 and i want to update it to lollipop but i don't know which firmware i have to flash. I don't want any brand-software with useless app pre-installed on it. But i saw that for italy doesn't exist no-brand firmware, so which would be better? Then after the upgrade to lollipop how i can root it? Can you like me a guide or tutorial? Thanks :3

[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
