I have tried several times, and the installation fails on the ‘Recovery Installation Step’, with the entry in the log
Blockquote2023-05-16 16:18:30,157 DEBUG [Thread-11] e.e.i.t.CommandExecutionTask [null:-1]
(debug)Sending ‘boot_b’ (65536 KB) FAILED (Write to device failed in SendBuffer() (no link))
I posted the wholel log at the website linked for documents.
The Pixel 4 has Android 13 installed
On the easy installer doc, and on screen when using the istaller, it does not say anywhere that you need Android 12 installed. On the advanced instructions for the Pixel 4, it does say that.
Could that be the problem, that I need to downgrade the Pixel 4 to Anroid 12, or is an Android 13 version coming soon enough?
With the easy-installer, usually the stable version will be installed. For the Pixel 4 that would be S (Android 12). To rule out your assumption, you would need to have a lower security patch than eOS has. I don’t know if your error means that but it is a common issue people have
There is a android flash tool with which you could downgrade.
If you choose your download to Android 12, S, you should ensure that you do not take an SPL in advance of that which is offered by Easy Installer, or else you will still risk refusal on the basis that you are attempting to down grade SPL.
Easy Installer will not down grade either Android version nor SPL.
The installer does change the Pixel 4 to fast boot mode (I think that is the right term) and unlocks the boot loader.
Are these things different than what you mention above, that the log shows the phone is not detected?
Yes the phone is working with the original Android installed. It just gives a warning that the bootloader is unlocked. I am not currently using the device. I still want to install e/os in the future, though.
