If I only write to the system and gapps, then I can boot normally.

If magisk are written, the system cannot be boot on and restarts in a loop.

Correctly installed Rom Lineage 19 and MindTheGapps in xiaWRomi MI4C with 2Gb of storage. I have the TWRP Orange-Fox and the F2FS partition, I formatted the data and did a zip installation lineage-19.1-20220518-UNOFFICIAL-libra, deleted in system/system/fonts Notosans CJK in case there was not enough space to install MindTheGapps-12.1 .0-arm64-20220416_174313.zip.
Everything worked fine, after setting up the Google account.
Don't install Magics, because someone said it was incompatible.
If I find any error, I'll tell you about it. Thank you very much

Edit:I just installed Magisk v25.0 working perfectly.
Edit: After using it for two days with internet, Sygic, Google Maps, iGo and it works fine. The problems that I detect are: some unexpected restart, some delay on the unlock screen. The GPS connection is not precise, but it was already with the previous ROMs and the battery is fine.
Thank you very much for keeping MI 4c alive

Hi @tipzrickycheung,

Thank you for the ROM.

I use Mi4c, 3GB RAM. I flashed recommended Firmware before I clean flash your ROM. What I've noticed is that the phone is getting quite hot when not much loaded. Also there are issues with Bluthooth. It happens each time I connect to Hi-Fi system and then I can't do much on the phone, it freezes. I have to restart it.

Thank you for your help.
I am not an expert to make a tutorial, my way of proceeding is: trial and error.
The process is the same that we use to install other previous ROMs.
My experiments are always with a device that I don't need, so if it doesn't work the first time, I try again ?????
If you have any specific problem, you can comment on it and we will try to find a solution.
Cheer up and good luck

Now i have TWRP installed and MIUI 9.5.2.0 (NXKCNFA) running on my device.
What should be the next step? To boot into TWRP and wipe the phone? Than i should copy the LineageOS 19.1 on the phone?

Do anybody know where to post kernel related questions? I've just got to the point of building the nethunter kernel tree for libra, but I can not boot the anykernel it generates. I know I'm missing parameters, but nethunter documentation is not helping, at all... :(
