Thinking About Starting an Xperia 1 III Port

Hardware Adaptation
1

Hello.

Recently I got my hands on a used XQ-BC52. So I am thinking about creating a port for this device. It has some really good hardware - the SoC has great performance (1 x 2.84 GHz + 3 x 2.42 GHz + 4 x 1.8 GHz ), the screen is nice and clear and it has 12GB memory. Overall, it is a solid device. I want to give it a second life.

The Technical Stuff

So, this device is running Android 13 factory. I have verified that the bootloader is unlockable.
Now, I see that it is part of Sony’s open devices program. Also, there are Lineage builds based on Android 16 but I do not know what binaries does it use - sony open devices or ones extracted from the stock android? I could not find any information aboutthe state of the LOS port, e.g. what works and what does not.

My question is: if I were to embark on such an adventure, what should this port be based on? Sony open devices or the LineageOS stuff?

Based on @rinigus work, I guess you should go with Lineage builds. See this: New binaries / blobs for Xperia V and IV : What is happening actually? - #182 by rinigus

I can only recommend Lineage. SODP state for 1IV was extremely bad and I wouldn’t count on it. As LOS is officially supported for it, go for it.

Also, I suggest to use LOS21 as we do for Xperia 1IV/5IV. LOS23 maybe too new for porting.

I would be very interested in this port. I own a 1III and would be happy to help, even though I have no programming knowledge.
My phone is available for testing purposes.

I am trying to build LOS21 as recommended here but I got stuck on extracting the vendor blobs.

I decided to follow the official guide of extracting the binaries from one of the builds here (they are LOS23 but this should not matter).

I mounted all required images from the archive. then I ran the extract-files.sh script which extracted 2700+ files which is a lot but it could not find some small number of the files, like these for example:

extract-files.sh

This is a non-exhaustive list of the missing files, full log attached.

Why are those files missing while device/sony/sm8350-common/proprietary-files.txt list them as required? How are the official LOS builds for this device running when those files are missing?
