From what I know about anti rollback protection, you can downgrade or upgrade without problem if you don't relock bootloader.

RE: Fairphone 5 bricked while attempting to install Ubuntu Touch
@iz_zi
I guess you downgraded your Fairphone 5 from 14 to 13 for installing UT.Sad you didn't get the info before but :
You MUST let bootloader unlocked for being able to install AND run Ubuntu Touch on most devices (I think only volla devices sold preinstalled with UT have bootloader locked and can run like that).
When you downgrade Android version on recent android devices like FP5, YOU MUST NOT relock bootloader, because of the "anti rollback protection" google imposed on recent devices specifications.
There is a warning for that particular case ("downgrading", which can be on the same android version, because most important here is the security patch date) on the Fairphone website downgrade/manual install tutorial.Sadly your only way now is to contact FairPhone support.

The warning at boot is because bootloader is unlocked.

RE: Fairphone "gen" 6 is there !
@Twigg said in Fairphone "gen" 6 is there !:
From what I have read above, it looks like there haven't been too many changes from FF5 to FF6, so perhaps that makes it easier for Ubuntu Touch to get released on the FF6?
I said that ram and rom are the same amount, and screen only 30hz more.
But SoC is completely different, hardware is different.
I guess you misunderstood me, I didn't say FP6 is the same as FP5, I said Ubuntu Touch experience should be the same under FP5 and FP6. -
RE: Fairphone "gen" 6 is there !
@rdfrs
It took 2 years for FP5 to reach device page with for now "only" devel channel.
So I would expect the FP6 takes the same time.This thread is for info only, FP5 is cheaper pristine, can be found even cheaper used, and the FP6 don't have more ram (8GB) or rom (256GB) than the "big" FP5.
It's quite the same phone in definitive, I don't think a more recent Qualcomm middle class SoC will make Ubuntu Touch better, even the 120hz of the FP6 OLED screen will not make the 90hz of the FP5 OLED one outdated.
If you want a Fairphone with UT now, get the FP5.

RE: For devices with no Notification LED is it possible to use flashlight instead?
@ikoz
That's exactly what I expected to see with amoled smartphone and no led.
And for preventing burning problems, changing the pixels used every flash. -
RE: Fairphone "gen" 6 is there !
@ikoz said in Fairphone "gen" 6 is there !:
It will also support mainline Linux
Wow, that's a big new thing here !

RE: What are the possible devices that can likely to be ported in span of 3-5 years?
The porting forum is for the discussion of porting work, build errors, and other wonderful hurdles when porting Ubuntu Touch.
So thread moved.
For a device to port it depends, lot of time, of what device a porter got and want to port.
But what I can tell you is that the just released Fairphone 6 will be ported, not soon but probably later (after FP5 reach stable state I guess, on 24.04)

RE: What is my Halium version?
@Alain said in What is my Halium version?:
UBPorts Installer is built upon Halium, I think.
No it is not.
Halium is related to installing a "not android system" on an android system native device.
Trivially it is a software that Iinks android hardware device drivers and Linux kernel ("extracted" from an android rom) with GNU/Linux operating system ported to that device.
https://halium.org/I see no "halium" anywhere on my computer.
That's perfectly normal. You, as simple user installing UT on a device, don't have to deal with halium.
You only have to unlock bootloader and install the required android rom on that device.have Android 11, but how do I check my halium version?
Again, you don't have to, you "only" need to install the required android rom.
If it's android 10 then android 10 it is...
No halium stuff for you.To summarize, what you need to know, is the android version installed on your device.
And if needed you have to install the exact one required before installing Ubuntu Touch. -
RE: FP5 finaly in device list !
@libremax
Well, I'm not on ubuntu-fr and I don't survey device page everyday -
FP5 finaly in device list !
Still only devel channel though.
https://devices.ubuntu-touch.io/device/fp5/
The Fairphone 5 is currently the best supported device with Ubuntu Touch. Its powerful processor, combined with the silky smooth AMOLED display, gives an appealing experience to anybody who uses it.

RE: Update port for Ubuntu Touch 20.04 on Xiaomi Mi 6
As a mature and comprehensive human, you'll easily understand that we need to talk the same language in order to keep the forum clear and easy to read, and to search on.
As a mature and comprehensive human, you should understand that we, all non english native speaking persons, are making the effort to communicate in the chosen language for us to talk each other, because it is one (simple) rule here to follow.
I really would prefer to speak french anywhere, anytime, but hey, as a comprehensive and mature adult I know that we can't always do whatever we want
