So for me, flashing TWRP gave me the TWRP background but no menu. Any idea what I’m doing wrong?
Ah, this means the device is encrypted. Before installing TWRP make sure to wipe data/cache and after its installed through Odin make sure you immediately go into TWRP, don't let it boot first. When your in TWRP make sure to flash the decrypter before booting up.

Look at the TWRP recovery steps again just double check.

Also, I thought tripping Knox was permanent, after checking Knox being tripped in this OS, as expected it was tripped, however after reinstalling stock firmware (rooted version) Knox is now nolonger tripped.

Ain't able to flash

Hello everyone. One quick question.
When I try to install the ROM image in TWRP, the device will restart on it's on. Any ideas of what the problem could be?
I tried to reistall samsungs firmware, reistall TWRP recovery and retry to intall the ROM but no luck.
Thnaks in advance for the replies...

Cheers,

F

Thank you, this really helped. FInally got it to install. However, sometimes after using some apps the phone becomes really slow and sluggish (most noticable after using video apps, like youtube). Does anyone else also see this behaviour? I had to reboot the phone to get back to normal.

So far i really like the rom, everything I use works (bluetooth, hotspot, wifi, 4g, camera).
