Flash AOSP

[kiubaz]

Hi

I have Xperia XZ2 Compact with Android 9 with unlocked bootloader. was trying to flash a ROM built from AOSP. I followed this official Sony's instruction: https://developer.sony.com/develop/...build-instructions/build-aosp-android-p-9-0-0. I have just added a field in xml that is used in Information about phone activity. The build was succesfull. In the end I get an information: "Your device is corrupt. It can't be trusted and will not boot". I did wiped the data, system and dalvik before flashing in TWRP. What the hell is going on?

Flashed OEM?

Yes, OEM was already flashed to the one from XperiFirm.

That's the wrong OEM.
Please follow my instructions in the SonyAOSP thread.
Or step 7 of your linked guide from sony.

So now the following steps to do:

1) download oem.img from https://developer.sony.com/file/download/software-binaries-for-aosp-pie-android-9-0-kernel-4-9-tama/
2) wipe data/cache/system,
3) from package built from AOSP do this
fastboot flash boot out/target/product/<device>/boot.img
fastboot flash system out/target/product/<device>/system.img
fastboot flash vendor out/target/product/<device>/vendor.img
fastboot flash userdata out/target/product/<device>/userdata.img

and lastly

fastboot flash oem img_from_point_one.img ?

Allright that's original firmware but what if I want to make my own changes in AOSP? Thats the point.
