I tried all roms... The best one was aicp, but the castor builds after the 24.06 build was corrupt. Carbon Rom is a little bit buggy on castor and Resurrection Remix is the best choice
How To for the best experience....
1. Install twrp 3 recovery (twrp 2.8 may work too) and wipe - factory reset...
In one instance add then these to install....
2. remix resurrection is the latest and most useable release for z2 lte
3. Install BeanGapps
after reboot and config go back to recovery and install these:
4. magisk 14.2 (beta) via twrp recovery
Reboot again and start magisk manager
5. Download and install (both in the manager) the Module "Universal SafetyNet fix"
reboot
6. You are done & have fun :victory:
You need for this:
twrp 3 recovery (flash via adb)
remix resurrection rom for castor
BeanGapps
Magisk 14.2 (beta)

I did not unlock the bootloader, so I can only install the firmware of sgp521 with flashtool. If you unlock it, you may be able to flash the rom above

I think it's only possible if someone repack Nougat developer preview for Xperia Z3 but tablet version (which have same hardware). Developer preview puts easily on locked japanese devices (which cheaper because of lock).
I also want Nougat on japanese Z2 tablet, because even Developer preview by my experience on my japanese locked Z3 smartphone are very fast, very good battery (a week on one charge, on z2 tablet battery is problematic short on all Androids from 4 to 6) and there's multitasking (2 windows), i don't have any bugs on it with latest Google Services updates (except not working NFC). Developer preview (last one, NPD56N) looks like little unfinished but fully usable on everyday basis.
I'm assuming the Z2 tablet battery on Nougat will be much better and total OS more usable with multitasking, i'm using Z2 tablet to only watch Twitch or Youtube so i don't need super security patches and etc.
I've tried to use Android 6 firmware as base to write Nougat developer preview partially (note: on locked japanese tablets Marshmallow not supported officially, it's only possible to write it using parts from official EU tablet versions-fully working Wifi version full must be overwritten by cellular version partially (only system and kernel) to get working cell and NFC) but the main problem is boot.sin, anyway writing smartphone version was just test, it's like starting but no image on display.
So, someone need to repack the old Nougat Developer Preview from Sony to tablets specifically - because it's only working Nougat version on Snapdragon 801 with locked bootloader! Unfortunately i haven't found anything googling all Internet, no one even tried that.
