FPOS Android 10 download WANTED

[FP3plusRT]

Running FPOS Android 11 on FP3+.
Want to try Halium 10, which is to be installed from (Fairphone OS) FPOS Android 10.
FP does not provide older versions, which I understand.
Where can I find a stable Android 10 for FP3+ ?

@dr4Ke, here you go:
https://forum.fairphone.com/t/ubuntu-touch-installieren/74814/7
It's a thread in the Fairphone-forum where Luksus posted an FpOS (FairphoneOS) Download.
Still works, since I've just done installing UT on my FP3, even tho it's not the latest FpOS based on Android 10.
Just follow his (Luksus) advices and you will find the way to succeed aswell. But since it's a german Thread I will tell how I did it.
I just booted into a TWRP.img thats been made for the FP3 and cleaned Cache and Data.
Second I restarted into Bootloader where I used the FP3_Flashall (as described here: https://support.fairphone.com/hc/en-us/articles/360048660371) which I got from the ZIP-file that can be downloaded through the second link in Luksus' posting.
Afterwards you could directly run the Ubports-installer Luksus wrote. Nevertheless tho I just tried the ROM and enabled ADB. But I guess that could be skipped just as he wrote.
Best of luck,

@3r853n & @luksus : Found all information and files (thanks).
Started from FP3+ and Android 11.
After flashing Android 10 (md5 checked and correct) FP3+ reported "Can't load Android system".
Tried UBports-installer, same result. Cleaned Cache and Date with TWRP and flashed again. Same result. Back to Android 11 same result.
Something broke in the first step?
Any suggestions?

@fp3plusrt
According to this post on the XDA-Developers forum, the "rescue party" - as the screen is seemingly called - should be fixable.
It is mentioned that some keys got messed up somehow, so you should be in need to flash some stock ROM. Dunno which ROM is meant exactly and if this is even of any help but you may try this approach.

@fp3plusrt did you check "wipe userdata" in ubports-installer?

if yes, ubports seems not to be installed.
Maybe the device switched slots (A/B: it's a fallback android installation, if some OTA update fails) at some point.

You could try to run the ubports-installer again.

  <Already tried
  ubports-installer (nice tool) offers me three flavours of 16.04/arm64/android9. Tried 'stable'.
  There UBports complains (FP3+ screen with UBports-installer-logo) "Can't load Android system"

@fp3plusrt could you please provide a screenshot or photo of that situation?

Here is what I was talking about .
After copying photographs for this post, I reconnected FP3+ and restarted ubports-installer (root session). Meanwhile I started writing this post (user session). After some time FP3+ came up with Ubuntu Touch. No idea what did it.
Differences from before:

1. FP3+ was disconnected/reconnected (same usb2 port). Meanwhile another phone had been connected to this port.
2. UBports-installer was run twice.

Glad that I can now discover UbuntuTouch.
Thanks to all who helped. Vielen dank für die Hilfe
