If anyone gets the red warning at the start, this over TWRP or with adb debugging enabled, should fix it. This is also only needs to be done once.

[COLOR="Red"]THIS MAY WIPE YOUR DATA![/COLOR]
adb reboot "dm-verity enforcing"

* Alternative you can short/once press the power button to continue the boot process.

Do not get how you do this over TWRP?

Open an adb terminal on your pc, connect an usb cable and paste

adb reboot "dm-verity enforcing"

Dual sim should work but I couldn't test since I only use 1 sim card.

Maybe in Terminal in TWRP

Maybe in Terminal in TWRP

That would be just

reboot "dm-verity enforcing"

Don't know why but my phone just bricked after flashing this. I flashed it the same way like I did with all Oreo roms. My steps:

_Wipe data/system/cache/dalvik.
_Flash the Universal bootloader and A2017G modem from the link in OP.
_Flash Lineage OS 15.1
_Flash micro Gapps
_Wipe dalvik/cache
_Reboot

My phone stuck at the screen saying that my device is corrupted, I cannot boot back into TWRP also. Any idea ?

*Edit: I got it back to TWRP, will try again

This over pc adb terminal

adb reboot "dm-verity enforcing"

or this inside of TWRP

reboot "dm-verity enforcing"

Is there an instance where this has to be applied again? If you reinstall the bootloader, for example?

Probably or if you install stock again, I think that will be enabled again, but any other ROM shouldn't touch that state.

 

[OrdenKrieger]

The "in call audio/speakerphone" bug has been fixed by the way, if anyone wonders.

 

[DarkQuark]

I have flashed it successfully and am running it now. I will add all my apps and what not and see how it goes.

 

[Raffelberger]

Really excited for your experiences with this ROM and if you would prefer it over the ZTE Oreo Beta by Nfound in case some.of you are running that rn. ?

Can someone tell me if HDR+ on the modded Google cam works or not? Also the AKM DAC?

 

[FuzzyDunlop9]

Hi I have a2017 Chinese model running v3.0b11, MiFavor 5.2 should I still install the Universal bootloader and modem to be on the safe side

HDR+ works and the DAC always worked in headphone use case. Even on 14.1.

Yes.

So I was having FC issues with just the Google App. I downloaded Gapps again and reinstalled Gapps. Now I get stuck at the LOS boot animation. I am trying to get back into TWRP but I am not sure of the key combo since the whole "press the power key in 30secs" thing at the bootloader screen. Thank you.

-EDIT-
Got back into TWRP. I hit the volume keys after the power button message. Then I picked recovery from the bootloader menu. Then I have to hit the power button on the next go around and it goes into TWRP.
