F2fs IS supported, but in my view, it is a ****ty format: it takes years to develop a stable system and the only ones with the know how are Microsoft and Linux people.

Encryption: On stock, there is no encryption option at all. On other custom roms encryption wouldn't even finish successfully, because they either don't know or don't want to implement it. Jaguar is the only one for Z2 that can encrypt data. It will take time to fix keyboard issue: I wouldn't be surprised if Nougat is configured to look for Google keyboard, instead of AOSP one. You might want to try to install and set it as default...

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
That's because you don't read install instructions, which say that you can't flash clean releases after r11. You need to flash r11 first, reboot and let it run for a few minutes. Then you can flash the latest release dirty, i.e., without wiping data.

How to do that?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] STARK0711:
Take the chinise zui rom 1.9 and flash it via qfil on pc than boot in that rom

Now go to edl mode and again flash 3.5 dev version with qfil

After that u have to unlock bootloader and flash twrp again as 1.9 locks down the bootloader

Than after unlocking and flashing recovery try jaguar and see

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Every method is risky, and no one will say it will work 100%. Rumor has it Chinese baseband 1.70 is newer than Indian 1.76. Why? Because 3.5 firmware release is obviously newer than 2.x. But no one knows for sure. OEMs don't change every file and if they do, the new version is higher (1.76) than old ones (1.70) I have tried both 1.76 and 1.70 and see no difference. Also, there is no difference in signal strength for me. It is possible that other partitions from 3.5 are involved. My preference is always to flash full firmware, as opposed to baseband only.

Edit: Plus, you are on Nougat and most likely you don't need Oreo firmware...
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] pkn267:
Ok now I will fash the full firmware but pls provide me any relevant post from where I can do it. I think fastboot flashings wasn't effective . U pls tell me which baseband will work in both nouget and Oreo?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Read this post. https://xdaforums.com/showpost.php?p=72407849&postcount=762 There is a full Indian firmware there with 1.76 baseband (don't use Chinese link there). This is done by me for TWRP flashing. Read instructions carefully. If you do something different, you will brick your phone.

So that means I will have to only download stock 2.5 firmware that is provided in last?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
After upgrading and before flashing Jaguar, flash stock 2.5 (deodexed) to enable volte. After that, wipe system/data/cache/dalvik and flash Jaguar. Why stock deodexed? Because that one only includes rom, not firmware (which you don't need).

Hike messenger from playstore which is messaging app is not working could u pls help its working on your oreo !!!
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Mokee is based on stock. For Whatsapp not knowing you are on custom rom, you need Magisk hide. No custom rom could fool root checking apps without Magisk.

Any app requiring accessibility features won't work on Jaguar N (read post #3). Also, see my response to the other poster above. Also, I remember someone else saying that hike won't work only if restored, as opposed to setting everything fresh. Or the other way around. So, try the other way.
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] STARK0711:

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] Vikas Gautam:
[MENTION=5075064]optimumpro[/MENTION],

I can't confirm if accessibility is the reason but we are certainly not importing hike backup as the initial install gets stuck.

what about the other game I mentioned i.e. Hero legend shadow stickman. When I install and start it. It says - 'app stopped working' straightaway.

Also, if Hike Messenger is working in Jag O(as confirmed by [MENTION=7262081]kashyapp[/MENTION]), it means accessibility is working in Jan O. right? Meaning, can you confirm accessibility is the culprit.

---------- Post added at 07:39 PM ---------- Previous post was at 07:36 PM ----------

[MENTION=7262081]kashyapp[/MENTION], what did you figure out? did you managed to start hike?
[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
I don't use hike messenger, but if you have confirmation from someone else that it works in O, then it is true. You can safely move to Jaguar O.

Just remember, most likely you don't need the latest dev firmware, which is unstable and may cause bootloops or kernel panic.

[Lenovo ZUK Z2 (Plus) ROMs, Kernels, Recoveries, & ] optimumpro:
Every time you do factory reset or flash baseband, you must run stock rom once, so that volte modem is selected. This is because custom roms have no access to it.

For Jaguar nougat you have to select the nougat one from the mods

What temperature do you have as 'overheating'? Also, install kernel adiutor and adjust temperature in thermal by a few degrees down. I wouldn't use any other mode, including 'sun cooling', as those degrade performance.
