Thinking About Starting an Xperia 1 III Port

Max-Might · 21 November 2025 10:42

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

My wife did use the lineage android for xperia 1 iii some time ago and i can confirm that all featueres of the device did work

rinigus · 21 November 2025 17:12

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?

I managed to build and flash LOS23 on the device. So far everything seems to be working fine except the fingerprint reader.

Now I am following the HADK guide. Starting with a lineage-21 android base I have already patched hybris-boot and I am at the step of building hybris-hal and droidmedia but I get a dependency error. Here are my local manifests:

<?xml version="1.0" encoding="UTF-8"?>

The error log itself says this:

I’ve an Xperia 1 III (XQ-BC72) and I’d be happy to help, but my programming experience is limited to .NET (slowly learning Rust though). I’ve had a look at the GitHub repos for the other Xperia’s and I’ve no idea of what to do with any of it.

I can confirm that everything on the Xperia 1 III works with LineageOS. I’ve been using /e/OS on it for over a year.

davidrasch · 3 February 2026 10:05

I am not sure if you found assistance meanwhile. I can’t really help, only point out the place to look for help, hopefully: In the post Sailfish OS IRC channels moved to oftc.net there are links to the sailfishos-porters channel on telegram and matrix, which I heard are active and helpful
