Downgrade from LOS15 (Android 8.x) to 7.x?

Hi.
I want to downgrade my Mi5 from current Android 8.1.0 (LineageOS 15.1.-xxxxxx) to final stable 7.x.
Is it safe to just do a clean flash via FlashBoot with some MIUI stock ROM on 7.x and then TWRP to LOS 14?
Or would I experience some massive foooooook with partitions or sth?

If you want to go to Android 7.x rom from 8.x.x you may need to Format Internal Storage **if your phone was encrypted**.
You can also just flash lineageOS 14.1 because if you use LOS 15.1 you must use Facebook 8.5.x.x and above . That's enough for all of Android 7.x ROMs

Formatting is not a problem. Thank you.

I think you can flash this rom

This is aosp jdc with newest patches and fix

Yes. Wip all options. I did it and back to 20180220 version, using now.
After full wipe, use ADB to pull the .zip (rom and gapps) to the phone (I thought that is the best way) then flash this by TWRP.
Looks much better at all. Here could be, i need to fix somethings:

Any chance of building for starltesq?

Would it support star2lte?

It seemd that USB can't work in system, and my laptop can't access phone storage by using USB cable. But it can work in recovery

Try using a USB 2.0 port or a USB hub.

for Star2qlte what i have to download?

It seems the camera doesn't always work. It stays black and after a few seconds the OS says the app is frozen. For example stock camera works, Telegram camera works, but QR code scanners don't work, neither does Revolut's "selfie" activity.
Please let me know if I can give you any more information. I'm on build lineage_star2qltechn-userdebug 12 SQ3A.220705.004 eng.ubuntu.20221112.223657 release-keys with no gapps.

Boot into TWRP EVA-AL00

Hi,
I cannot boot into TWRP on my EVA-AL00, currently on Android 7. Bootloader is unlocked, ADB and drivers are installed, flashing now seems to go OK, but when it reboots, it goes into eRecovery or just doesn't boot at all.
I have installed the TWRP app via apk and I am using the latest EVA file from the TWRP website, 3.1.1.0. I've tried to access TWRP via adb reboot recovery or via the Volume up+power button, but both don't boot into TWRP.
I've tried to relock and unlock the bootloader, I installed Android 7 via HiSuite (I started out on Android 8, where the flashing only resulted in a broken recovery with Error 11 and 2), I've used various variants of installing TWRP via SRKTool and others, no success.
Endgoal is to flash a Android 9 or 10 ROM on this phone, for which the best method is via TWRP. If there is another way to install that ROM, I would also be happy.
Any suggestions are welcome!

I tried 3.1.1.0 from TWRP website too,
can not reboot into recovery,
if you are in andriod 8.0 now,
have try of twrp 3.2.1-0.
and andriod 8.0 support Project Treble,
you will find Lineage 16.0 (9.0) rom in XDA,
then flash it in fastboot mode.
