flash on your own risk.
This is for experianced people only, because theres no working TWRP yet. If you dont know how to read stop here (funny eh ?). Also if you dont wanna follow steps bellow because u know better. Goodbye. I dont wanna listen to you cry here. I will not help you.
opposite of what happens if you flash in twrp, this procedure will flash to the slot whis is active now. if you know what u r doing u can flash to any slot u like.
Despite the red text theres really no big danger here if you follow the steps. I just wana scare away newbs.
android 10 shipped devices have fastboot like we know it and its pretty much useless. and they have the new fastbootd (google it).
1st. get into fastbootd.
option a) from old fastboot, type: fastboot reboot fastboot (funny eh ?) another google miracle to not name it fastbootd.
option b) if you have a running os with adb: adb reboot fastboot
this will bring you to OOS chinese recovery look a like, but its fastboot. to test that u r in the right place try a fastboot command. fastboot getvar all for example.
unzip ROM using payload dumper
option a) if you are on linux
fastboot -w //this will wipe all your data. you need to do this only on first install, not on updates.
again! fastboot -w // will wipe all your data and is needed only on first flash
fastboot -w fastboot flash boot boot.img fastboot flash system system.img fastboot flash product product.img fastboot flash vbmeta vbmeta.img fastboot flash vbmeta_system vbmeta_system.img fastboot flash dtbo dtbo.img fastboot reboot
unfortunately because of the flashing procedure I have included gapps. when twrp exists they will be gone.
Updating: (WILL WORK ONCE OFFICIAL)
Use OTA inside rom for updates
if u did something else. we dont need/wanna know about it in the thread
May the force be with you
