Xperia 10 ii and Android 12

In order to flash my X10ii running Android 12, I am using an USB hub because the procedure fails with USB3. The instructions are about using ASOP Android 10 but I have also downloaded the ASOP Android 12 and tried to use it but it fails

https://developer.sony.com/file/download/software-binaries-for-aosp-android-12-0-kernel-4-19-seine/

I can edit the flash.sh script in such a way, it will take this image instead. Does this make sense for you or ASOP Android 10 is the unique option available? Thanks.

I have found this thread about using ASOP Android 11 and the test failed but no harm have been done. The test was done on March 22th, possibly something might be changed in two months or not.

The supported Sony Vendor partition image wasn't found in the current directory.
Please download it from
https://developer.sony.com/develop/open-devices/downloads/software-binaries/
Ensure you download the supported version of the image found under:
"Software binaries for AOSP Android 10.0 - Kernel 4.14 - Seine"
and unzip it into this directory.
Note: information on which versions are supported is written in our Sailfish X
installation instructions online https://jolla.com/sailfishxinstall

That does not make sense. Why not just follow the instructions?

Just curious about Android 12 because the phone arrived with such version.

Remove the USB cable and bootup the device by pressing powerkey.

@espen reported an issue with Bluetooth after flashing SailfishOS over an Android 12 base on an Xperia 10 II (but everything else seemed to work fine, as reported by @farz2farz and @MDJ, too), and stated that his original Xperia 10 II on which he flashed SailfishOS over an Android 11 base did not show this issue.
Reference:

Can someone who flashed SailfishOS over an Android 12 base on an Xperia 10 II confirm or deny this observation (e.g. @farz2farz or @MDJ)?

For my own part I can just confirm that the problem persist after now upgrading to 4.5.0.24/25.

@espen, thank you for your reply.

The common theory about the Android base one uses for flashing SailfishOS making a difference is, that firmware components residing on some of the many partitions on internal FLASH memory become updated. This could be some DSP firmware (so calls or any other audio might be affected: echo, distortion, loudness etc.) or firmwares for Bluetooth, WLAN, GPS etc. Some of these firmwares are in the “Sony software binaries” one uses for flashing, but I have never seen an analysis which, and this could change from model to model. Also Jolla only utilises a single, old version of “Sony software binaries” for each Xperia model (and tests have shown that other versions do not work well), so this is a constant factor.

Long story short: If the Android base which was installed before flashing SailfishOS makes a difference, no SailfishOS update is going to change that; only reflashing to a different Android release and then flashing SailfishOS again is going to alleviate such an issue.

Are you still absolutely sure that the first Xperia 10 II you owned did not show this Bluetooth issue in exactly the same scenario (i.e. really nothing else changed, but the Xperia 10 II device)?


P.S.: If you want to know for sure, you can backup your SailfishOS partition by dd onto SD-card via recovery (for Xperia 10 II and III this requires flashing the SailfishOS recovery onto the boot_a partition), then flash an older Android version via Emma (a free trial install of Windows in a VM seems to be sufficient), boot Android once for a few minutes (or longer, if you like to play with it), flash the boot_a partition with the SailfishOS recovery again, restore the SailfishOS partition with dd from the backup on SD-card and finally flash the regular SailfishOS boot code onto the boot_a partition again.

Thanks for your description of the underlying factors!

What I know is that I had a X 10 II based on A11. It worked fine with BT in my VW car. (I’ve previously had BT problems with other SFOS phones, but I have had a series of phones (and VW cars) and don’t remember which worked and which didn’t. At least on one occasion BT started to work after an OS upgrade.) The X 10 II broke and I bought a new X 10 II that was updated to 12 and installed SFOS on it. I’m now not able to to hear the other part when operating the phone on BT in my car, (but they can hear me). I’m not aware of any particular differences between the two X 10 phones or the BT set-up, but I haven’t run a stringent protocol on this, so regrettably I can’t completely rule out any differences.

And no, I’m not going to go through all the hassle of downgrading Android. I’ve rather just bought a X 10 V, in the hope that 4.6.0 will run on it.

It is always possible to flash other aosp software binaries than the suggested. Some things might not work as expected though. I think you should go with a specific android version, that you can gather all the carrier blobs of your mobile operator for mms, volte and proprietary sim-addons, before partition/fs-system changes layout…

Yes, but this thread is basically not about the Sony Software Binaries (note that there is no such thing as “aosp software binaries”), even though some people regularly deviated into this topic, apparently because they do not comprehend the difference to …

It is about the Android base over which SailfishOS is flashed. This can make a significant difference, because along with the Android updates Sony deploys various firmware updates, which are stored on separate partitions on internal mass storage (“eMMC”) and thus are unaffected by flashing SailfishOS.

For reflashing the Android base, one must use Emma and start right from the beginning with updating Android to an appropriate release, flashing SailfishOS etc.
