I erased my OS and i need help!

[satet_br]

I've been trying to downgrade from android 9 to android 8 (stock) and gave some bugs, I've been trying to sort it out and erased my OS

When I turn on the phone the boot image appears and I return to the bootloader screen.
When I try to reboot with the twrp it says "No OS Installed! Are you sure you want to reboot?"

Sorry grammatical errors, I'm using google translator.

If you can answer me in a more formal way, I thank you, because it is better to translate in google

Note: my phone is: XT-1922-5 and

to speak portuguese

I await an answer, thanks.

Reflash Android 9.0 stock to get it working again. The entire firmware. Then I can walk you though downgrading. You have to be very careful

thanks for replying to me, but I already managed to install the stock rom with Android 8

for those who had the same problem is only to use the twrp version of 16GB and follow the tutorial that has at the end of the topic
