1) I've first flashed cepheus_images_V11.0.9.0.QFACNXM (the only one i have) with MiFlash (just erase with no bootloader lock), then i tried "fastboot flash vbmeta vbmeta.img --disable-verity --disable-verification" with error "unknown options" (maybe do i have to update fastboot and try again?). So flashed vbmeta without options...

Looks like your fastboot.exe is outdated when it doesn't recognize the parameters. Take the one from XDA thread. As you flashed vbmeta without parameters you probably now have a corrupted vbmeta which might be the reason for the bootloop.

Cheers

I there a way I can disable the left sided button which always launch google assistant ?

Same bug here... Google assistant keeps popping-up. Disabled mic permission for google services and disabled voice assistant on Google app fixed the problem, but you will not have voice recogniction and dictation funcionality.

Is there a way to have the miui 12 camera back?

Some mobile banking apps, like Unicredit, don't work. Is there a fix?

Thanks

Strange, maybe persist.vendor.bt.aac_frm_ctl.enabled=true solve that issue for me.

Enabling persist.vendor.bt.aac_frm_ctl fixed bluetooth audio stuttering for my Bose QC35 II on my custom build..

For people having the same issue it should be quite easy to test this by executing "setprop persist.vendor.bt.aac_frm_ctl.enabled true" in a root shell and reconnecting the bluetooth device.

I wasn't able to to resolve the issue by switching to SBC.
Disabling AAC in bluetooth settings didn't interrupt the audio transmission, so it probably was still using AAC.

good morning, is this rom still supported, has it any bugs?
yhanks

Yes this ROM still receives updates.

The only bug I encountered is with auto display brightness. Usually after restart it rocks back and forth between low and high brightness nonstop. To fix it I just turn it off, set some other value then turn it back on.

Other than that this ROM is working well for me.

I'm still having some issues with my phone unfortunately.

- When I plug in my earbuds, pressing the volume buttons suddenly act as a keyboard. (ie: minus selects different apps on the homescreen, plus opens the selected app). This started happening once I had flashed the firmware from June 14th.
- Contactless payment still isn't working because I can no longer select what NFC secure element the phone should be using. The original firmware had a menu with at least the options "HCE", "SIM". Online I read there might've also been a "embedded secure element" option, but I can't remember. All I know is that I had to select a different option in this menu before it would work for me. But with LineageOS this menu no longer exists, and contactless pay doesn't work anymore.

@Cozzmy13 Any bugfixes for this coming up? It's still often an annoyance making me actually consider just buying a different phone (which is a shame, because the device itself is pretty great)

Hey Guys i have a few questions to ask:

1. how can i setup Black Oled theme with the new LOS theme engine?
I hate the default (Google)Dark theme

2. Where can i disable the black bar under the Keyboard.
On earlier version you could do this by going to: Phone settings, Display, Navigation bar, and disable Show button to hide keyboard.
But where can I find it now ?

3. Face unlock isn't there as an unlock method.
I read that face unlock was part of the Gaps till end of January 2020.
Does anyone know how to get it working now?
