Introduction
LineageOS is a free, community built, aftermarket firmware distribution of Android 10 (Q), which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

What's working:

• Boot
• Bluetooth
• Camera / Camcorder
• Double Tap to Wake
• IR Blaster
• RIL (LTE/Dual SIM/SMS)
• FM Radio
• VoLTE
• GPS
• WiFi
• WiFi Hotspot
• USB (ADB/MTP/PTP)
• Video Playback
• Touch

What's not working:

I had updated my post. Any recovery with vendor support or any Android 10 arm64 should work. It's always recommended doing clean flash, e.g. full wipe when you switch between different ROMs. You may still try to do keep your data partition, but please don't report any bugs until you can reproduce them with clean flash.

Do I have a bluetooth connection problem for sound devices?

Thanks for this awesome ROM,its smooth n fast.everything works perfectly without a glitch.what I did first was changing orangefox recovery to op unofficial twrp via team win apk,without formatting it shows error in twrp n flashing with magisk it did boot up but to twrp again n flash again without it yes it works.I m okay with less customizations.BTW I m using official open gapps nano.Hats off to you.

 

[michal778]

What you mean by wipe vendor partition"s"?

I understand that I should wipe system, data, cache, dalvik, vendor?

 

[michal778]

Well, a huge disappointment can't flash lineage-17.1-20200628-UNOFFICIAL-rolex.zip at all. I'm using miui 9.2.6.0 and twrp that you posted. Can't wipe vendor because it's not showing in wipe list, so I'm wiping rest. It's says flashing was successful, but gapps giving error 30 and tells me my android is 7.1.2! Something is wrong. I'm doing clean flash from miui. It's not installing at all, so OS is broken or twrp posted. You tried that twrp?

EDIT: Yup it's twrp thing, i used another that allowed me to wipe vendor, and gapps now flashing. Sir, next time better check please.

Is this a question? I don't know what you have on your phone. As for me, I didn't check BT audio yet, but I hope to have some BT headset available soon.

Thanks for report, @michal778 and sorry for that. I don't remember where I got recovery that I had on my phone. But I found a recommended recovery on 4PDA, I had uploaded it to the same dir on my server and updated OP.
I had double-checked that I get working LOS 17.1 + GApps with it, by flashing MIUI 10.2.3.0 via fastboot first.

I flashed directly from crdroid 6.7 got some minor issue in twrp as mentioned in my previous post,instead of flashing fastboot miui 10.2.3 can we use minimal firmware of the same(size about41mb) in future.

 

[brunozod]

Sir congratulations for the great ROM! Any chance of this ROM becoming official?

Yes, sure. You may grab one here. I had updated OP, thanks.
