Hello,
ok, I’ve got questions about the installation guide.
First of all, 3 versions are offered in the download section for the Fairphone 4: /E /Recovery for Dev Build, /E /OS Build: R Dev (Security Patch: 2022-04-05) and /E /OS Build: R Stable (Security Patch: 2022-04-05). In the guide, they indicate to recover all the files and images in the Download section. Ok, but what version I install on my device? If I don’t want to have problems, I install the stable version? This is the first important point.
Afterwards, I must unlock the bootloader. I understood that I have to do this on my smartphone.
First, I want to know why I must enable and connect to wifi.
Second, in the point eight, I must reboot again into the bootloader. So, can I use the command: ‘adb reboot bootloader’ ,or, must I turn off the Fairphone 4 and Press and hold the Volume Down button ? The point eight is not clear.
Finally, after installing e/os, I must locking the bootloader before rebooting. Ok, but can I rebooting the system without locking the bootloader to see if e/os is launched and if it is good then locking the bootloader ?
If you have advice, suggestions, I’m interested.
Note: I’ve check the security patch level of my device (default) and it is less that the e/os security patch level, so can I install e/os without problem and can I lock the bootloader without problem after installing e/os ? I don’t know what is the security patch level for e/os 1.0.
Thanks.
