FP4 can install Android 11/12/13 and /e/OS 11/12/13 and PostMarkOS, except Ubuntu Touch

@MrT10001 I have some confusing, from my understanding, it should reboot to fastbootd mode when you edit the partition, right?
and PF4 have 3 mode such like 'bootloader' ,'recovery' and 'fastbootd' mode, 'bootloader' mode is 'fastboot' mode from my understanding,right?
so you mean, I need to switch to linux and use ubport-installer to install the UT will work, if like that i will try it. Anyway that should be partition problem,I need to find the way to fix the partition.

MrT10001

@liam You are missing the point.

./fastboot reboot fastboot

will put you into fastbootd which will enable resizing of the system partition. You cannot do this in fastboot or recovery.

Windows sometimes has an issue working with fastbootd therefore a workaround for windows users is to try a Linux system where it works better with fastbootd.

This is fastbootd.

@MrT10001 yes, I knew it. I already have this command on my step, and it also works and reboot as your screen capture, but it still have error message when use the partition command,can not edit the partition.

liam

use command: .\fastboot.exe getvar all show the partition already there

use delete command,can not delete it and resize it.

@liam You were running the Fairphone version of Android 11 before attempting the UT install?

liam

@MrT10001 yes, I already installed the Android 11 before tried UT installation. install UT failed and I go back install Android 11 again then tried install UT again, again and again failed.

MrT10001

@liam the Fairphone 4 stock Android should set the partition sizes correctly.

liam

@MrT10001 I have followed below guidance install Android 11, I really have no idea which step have problem, why can not install UT still show the same error.

MrT10001

@liam I see you are using Windows (fastboot.exe). Put the platform tools folder on your desktop along with the UT installer and run fastboot commands from there. Also you can try an older version of platform-tools to rule that issue out.

@MrT10001 Tried any way, still can not work, I want to give up for it, if anyone interest in this phone, I can sell to him.

MrT10001

@liam Reading here may solve the issue.

The critical partitions may need to be unlocked.

Install Android 11 and make sure the bootloader is unlocked.

Then unlock the critical partitions using the command in the linked forum post. If using Windows you may have to put ./ in front of the command.

@MrT10001 I already tried this command before, actually I can install Android 11/12/13 and /e/OS 11/12/13 and PostMarkOS, except Ubuntu Touch, the dynamic partition was deleted by me before, I don't know how to revert it that is the problem. it can install UT at the first time, after I resize and expand the size for 'super', that want to install back UT, it was failed till now, still can not find out the good way for fixing it.

MrT10001

@liam Check this out on the fairphone forums, you may have damaged the partition table.

liam

@MrT10001 I have refer to it before, resized and expand the super partition. it is UT problem, I can execute the partition operation like 'delete-logical-partition' in Android and /e/OS system, but after flash UT firmware image, partition not working.
