API 29 support (Android 10.0)

[dan-v]

Just wanted to open an issue for tracking this. Google released Android 10.0 on September 3rd with a new API version 29.

I played around with the Q beta 6 factory image last month and noted down some of my findings here: https://gist.github.com/dan-v/a366c2cff6ef5a2f7e0022a39b1d5b00. I bumped into a number of new issues that will require fixes or more research to get everything working.

Just to provide an update. Most of the devices are now booting and functional on 10.0 with changes in chirayudesai's fork. I also have marlin support in my fork.

Another update: Seems like there is another fork by the GrapheneOS guys that added support for sailfish yesterday:

Unfortunately none of the above forks work for me. Here's the error:

[] Running as root - using loopback for image mounts

Any ideas how to resolve? Thanks.

@Mawth which versions did you use exactly? In my case I used version 54998cb from the GrapheneOS work with the following blobs and this seems to have worked fine:

./execute-all.sh -k -d sailfish -a sailfish -b PQ3A.190801.002 -o sailfish-blobs

Maybe you are missing some dependencies? I am using the packages as described in this tutorial.

[Mawth]

Thanks for the reply. I added Branch "10" from GrapheneOS/android-prepare-vendor to my local_manifest. For sailfish, I believe this pulls in d1f9e96.

Here's the specific script I used:

sudo ./execute-all.sh -d sailfish -b qp1a.190711.020 -i /media/bluebird/aosp10/aosp_b_prod/sailfish/qp1a/sailfish-qp1a.190711.020-factory-0bb95222.zip -o ~/Desktop

In your example above, you're extracting blobs from a Pie image. I am trying to extract from 10. That might be why you were successful and I have not been? Anyway, I appreciate your time.

@Mawth - in the forked branches for 10.0, there is a new dependency on protobuf (e.g. if on ubuntu just apt-get install python-protobuf) which is used by a new script that downloads OTA updates and extract missing partitions that previously came from the factory image. This OTA extraction mechanism may just be a temporary solution, but depends on if the October images look any different or not.

GrapheneOS-Archive#4
here is my blob list in the comment and a fix to product partition file not being added,

[Mawth]

@dan-v - OK, thanks for that. If I understand correctly, then this method is currently not possible: "As an alternative to download images from Google's website, script can also read factory images from file-system location using the -i|--img flag." With the current scripts, it's necessary to download from Google's website. Next time I have access to a high-speed connection, I will try this method.

Android 10 factory images have removed certain images required for building OTA zips from factory image zip. They need to be extracted from bootloader.img & radio.img via https://github.com/anestisb/qc_image_unpacker. Have started working Android-10 support for existing devices. Pixel 4 devices will follow.
