Successfully installed Lineage 8.1 on redmi note 4 - BUT couple of issues to be sorted

[7875504044]

Hello friends,

I successfully installed Lineage 8.1 (along with gapps) on my Redmi Note 4 and is working perfectly fine (without any crashes/hangs for last couple of days. But there're some issues like

1) I tried to install TWRP multiple ways but it doesn't enter TWRP recovery mode on its own (when I press volume down+power) but instead it always stuck up at "Fastboot". So I use laptop to do that job every time I want to go TWRP recovery mode, by running 2 command at "cmd prompt" from laptop (this method works fine) =

fastboot flash recovery recovery.img
fastboot boot recovery.img

IF I try to install TWRP using xiomitool it throws "Error 1006: The device is offline or unauthorized" but from cmd prompt I see device list with "adb command" without any issue.

How can I solve this issue to make my phone to TWRP (without using laptop) when I press "vol-down + power"?

2) Now that I'm running custom ROM 8.1 on my redmi note 4, how to update it regularly, Does it get updates on its own OR should I manually download Lineage 8.1 updates/apply them?

3) I did NOT root my device and am not interested to do that unless its of great advantage. Please advise if I should do that. If yes, which method is the best one (Magiks/Supersu etc.)

Thanks!
