Changing rom used smp900

[Valholy]

Good day everyone, just got my note pro WiFi version? Already rooted and has custom kernel civz, tablet feels slow so I'm planning on changing rom maybe lineageOS but I'm concerned about the procedure because I'm not sure where I'm standing with every change done to this device, any help is appreciated I just don't want to brick this device trying to flash a new rom.

Currently it's running stock rom 5.0.2, 3.4.39 civz kernel and knox 2.3, if someone could provide a step by step on what should I do or check in this device to be on the safe road id really appreciate it. Btw I don't even know what recovery I have or how do I access it.

honestly most samsung devices are the same so id suggest getting the full stock system and using odin to revert to stock, from there start by getting a custom recovery and seeing what else you need to set up your rom

someone correct me if im wrong

someone told me that I just need to install twrp as it is and start flashing roms, dont know if this the best way to do it what do you think?

It could work just keep in mind that you don't know exactly what the previous owner did to it so if they installed a custom kernel you'll be stuck with that, could be a good thing could be a bad thing

You could always give it a shot and if it gives you problems go back to stock then TWRP then start rom-ing
