If u flash stock frimware with Odin without turning on bootloader ( OEM ) then your WARRANTY is STILL THERE  and will not trip Knox.
(Using download mode and official firmware from Samsung)

but 

if u turn on oem(or bootloader) or 
flash other funny things besides the stock firmware found on samsungs website (you will need to bear the slow speeds)
then u will void your warranty....

 so make sure to get your firmware with your correct region from  and

 if u know how to flash the stock rom do it or else follow tutorials on Youtube 


KNOX ?

imagine that Knox is like a "little copper wire" inside your phone which is controled by software. Once you install a custom rom or root, the Knox is tripped - in another words that little wire is cut in half. By doing that you ofcourse void your warranty and you can never undo it. I hope that clarifies it a bit.
 If you want, you can google "e-fuse" and find out more info about nature of knox...



- Wishing you Luck.

that e fuse a pain in the **bleep** tbh. the whole purpose of rooting your device goes to hell. and thanks to that Samsung has the least custom firmwares for mid ranges.

yesπŸ˜‚..

mostly because the whole Exynos has less custom ROM....
when i tried to get custom ROM for my old S5 Exynos one... lineage os was only good option... i tried 4 other ROMs too...

at last again i had gone back to official firmware...

anyways rooting old phones only makes sense to me...

rooting new phone will void warranty etc and some apps you Can't use

mid range Samsung is better now with M series.

j series was a joke series compared to Chinese counterparts

You are saying that Exynos were useless? Till date they are, however phones like Galaxy A6+ dont have proper TWRap support till date let alone ROM support. And it comes with Snapdragon 450. πŸ€·β™‚οΈ

@interchuppi bhai ...flashing official frimware from download mode will be fine...

if we unlock bootloader...that is enough for Knox to trip ....

Samsung is using knox to prevent people from using custom ROMs i guess...

i was saying amount of custom ROMs for Exynos is very less compared to SD and also quality differs too.

ohh TWRP is not available for A6...

what about CWP, redfox and orangewolf....?

ahh who cares about 4 series Samsung galaxy Snapdragon phone- may be that's why they might have not developed it.....
or there are less devs to do it...

Also .
over locking a mobile phone processor is simply damaging your phone.

don't do it.

mobiles doesn't even have proper cooling system to keep up with the over clocking heat generation... i would damage your processor permanently
