Hi! Great rom :) but i have two issues:

-Installing the kernel of Picsel Experience i got "Error 1: no ramdisk found to unpack" on TWRP.
- I tried to use the multi-user feature but it lags A LOT on the second account. On the principal account works good.

Thanks for the support!
After last update, system updates shows me available update, but when I click "download", it crashes the system updates app.

Hi! I have the lastest Xiaomi.EU (12.1.2) with A11. Is necesary flash the official A11 firmware or can i flash directly from Xiaomi.EU?

This ROM looks pretty nice, it's clean and simple and offers most features a normal user needed!
Because of that it's fast and I think the battery consumption isn't high as well :)

Please please keep your great work going on and I hope you keep the ROM up-to-date (for security patches from Xiaomi mostly, besides from bug fixes). That was one reason for me to step back from Evolution X, which was last updated in March 2021....

Thanks for your nice work, you've done here :)

ok there seems to be some problems with the fingerprint...
When booting the phone and you entered the 1st pin code, then the 2nd unlock via pin/fingerprint is bugged.
The icon for the fingerprint is at the same position as the 0 from for the number of the pin code entry...(If you turn the display of and on again its all fine as it should be. The fingerprint icon is below the numpad)

Second but bigger problem is you can't add fingerprints through the security settings. The device expects the fingerprint sensor to be on the backside of the device for some reason...Because of that there is no fingerprint icon on the display visible to scan your finger -> and the function is totally not working for the Xiaomi Mi 9T.

    Does Maps timeline works for you ? Since I'm on this ROM, there is no timeline, even if I turn it on/off. Location and everything is on, but it's not recording...
