Fairphone 4 android 12 install ubuntu touch
-
Fairphone 4 requires update to unlock bootloader, but ubuntu touch instructions say to use android 11. Can I update to android 12 and then install Ubuntu Touch? Or do I need to avoid updates on Fairphone 4?

@dp27thelight
If it says android 11 needed, then android 11 your FP4 must have. -
@Keneda So if Fairphone 4 requires Android 12 to unlock bootloader does that mean I'm screwed for now? Fairphone website say's to fully update Fairphone 4 before unlocking bootloader.

@dp27thelight I think you will be fine to unlock and install on 11, after all you will be leaving android. You can always double check here https://t.me/ut_on_fp4 our Fairphone group.

They say what they have to say, whatever reason they have to say so.
But i don't think when FP4 OS was android 11 you where not able to unlock bootloader on FP4.If you skip this step, the procedure may not work.
They don't say that your FP4 will blow if you try it with not the last software.
But like @Lakotaubp said, if you really want to be sure that will work, try the telegram fp help channel.

According to somebody else's testing installing Ubuntu Touch on Fairphone 4 with Android 12 should work.
I'm certain Ubuntu Touch will update installer for Android 12 officially in the long term as well.
I just want to test out the android experience on the Fairphone 4 before making the plunge to ubuntu touch. Ideally I want to use Ubuntu Touch, but just like to experience options. Just like you would with desktop linux and distro hoping.

It 'works' in that the OS boots and most things do work. But the correct drivers will be missing and you might experience some issues, like sound not working for instance.
If you do decide to install UT over Android 12, and then experience any issues at all, please install Android 11 then UT, then check if the issues persist, before asking for help with UT. -
@dp27thelight
According to the forum, it kind of works, yes...

@Keneda I'm already upgraded to Android 12. This was basically an automatic update when turning the phone on. I haven't unlocked the bootloader because it shouldn't really be unlocked unless I'm installing an OS. If Fairphone won't allow me to unlock bootloader on Android 12 so be it.
Is it true the you can't lock bootloader with Ubuntu Touch? I don't fully understand bootloaders in the smartphone world, but from what I do understand it's less secure to have bootloader unlocked and might cause certain banking apps to not work which I don't use anyway.
If Ubuntu Touch will be a long running project, I'll assume will likely see Android 12 replace 11 in the coming years.

That is true.

Of course they'll let you unlock bootloader under A12.
But if you want to install UT and intend to have a full working phone, then you'll have to downgrade to android 11 FP OS (keeping bootloader unlocked of course).
And yes, maybe some day android 12 will be a basis to install UT, but for now, most recent UT ports are based on android 9 or 10.
FP4 is the only one in my knowledge to be based on 11, and that could stay like that for months or, more probably, years.

@Moem thanks for letting me know

@Keneda I decided to get a second Fairphone 4 to run both Ubuntu Touch and FairphoneOS. I want to clarify the core issue. If I follow the instructions of Ubuntu Touch, I will not be following Fairphone instructions for unlocking the boatloader.
That means they're is technically no absolutely safe way to install Ubuntu Touch on the Fairphone 4 at the present day. If something goes wrong unlocking the bootloader on Android 11, Fairphone has no reason to provide support because you wouldn't be following they're instructions. If you unlock the bootloader on Android 12 and install Ubuntu Touch you wouldn't be following Ubuntu Touch instructions.
Seems to be a disconnect between the two communities.

@dp27thelight
Why don't you just do like the member i just gave you the post link above, he had no problem downgrading to A11 after unlocking bootloader under A12, and then installed UT without problem...And Fairphone community has nothing to do with how to installing UT on FP. Here on ubports forums are the UT experts, and porters, and devs, and members like me.
On FP forum, there is only members (some for sure experts in FP and FP OS, but not in UT).
Anyway, do like you want ^^

@Keneda Looks like you don’t need to update fairphone 4 to unlock bootloader. If you update fairphone 4 it will upgrade to Android 12 which isn’t officially supported by Ubuntu Touch.

@dp27thelight
Looks like we're going round in circle here... -
Upgrade your FP4 from A11 to A12, unlock bootloader, downgrade from A12 to A11, install UT, enjoy
-
The method for unlocking the bootloader is the same on 11 or 12 that does not matter. You just need to unlock the bootloader.
The only part I am not 100% on is if UBports works from android 12.
Every OS including us tells people to be on the latest version todo some stuff. In this case as android is going anyway it does not matter. -
Just checked in FP4 group and yes you can install UT on android 12 but a lot of stuff will break so please don't try. There is also no issue with unlocking the bootloader on 11 not 12. The end.
