LoadImageAndAuth failed: Android-P preview-3 on Pixel2 (walleye)

[cine...@gmail.com]

Hello there,

I have built the p-preview-3 latest code and flashed my Pixel2 (walleye) but it booted up with a "LoadImageAndAuth failed" error.  While searching around, I couldn't find much information about flashing a Pixel2 in general.  Does anyone know what I have missed?  This is what I have done:

1. install the official P-preview-3 Beta Release (walleye-ppp3.180510.008-factory-5a8b6a89) from https://developer.android.com/preview/download.  After installation, the OS works fine on Pixel2.

2. download p-preview-3 code.  Applied 3 fixes, thanks to the hints from this post (https://groups.google.com/forum/#!topic/android-building/JfgzeR_S9N4).

3. download binaries 4851836 (meant for "master" branch) from here: https://developers.google.com/android/blobs-preview

    tar zxvf qcom-walleye-4851836-f4104c55.tgz

    tar zxvf google_devices-walleye-4851836-157f5216.tgz

    extract-qcom-walleye.sh

    extract-google_devices-walleye.sh

4. compile

. build/envsetup.sh

lunch aosp_walleye-userdebug

make -j16

5. "adb reboot bootloader" and then send these commands

    fastboot flash boot out/target/product/walleye/boot.img

    fastboot flash dtbo out/target/product/walleye/dtbo.img

    fastboot flash system out/target/product/walleye/system.img

    fastboot flash system_other out/target/product/walleye/system_other.img

    fastboot flash userdata out/target/product/walleye/userdata.img

    fastboot flash vendor out/target/product/walleye/vendor.img

    fastboot reboot

6. device shows "LoadImageAndAuth failed".

I'm able to recover the Pixel2 by flashing the official Beta release again.  But I would like it to run with my compiled binaries.  Any help is much appreciated!

Regards,

CSG
