after spending at the PC for several hours trying to install /e/ OS on my FP3+ and reading different threads in the forum I decided to sign in here myself and start a new question.
I bought a FP 3+ second hand with pre-installed Android 11.
Caution: Do not install /e/OS on top of a higher version of stock OS. Before installing /e/OS ensure your device has the latest stock OS of the same version as /e/OS. If only lower versions of the stock are available then install the last available lower version before installing /e/OS.
But when choosing a version here I find only Beta-Versions for Android R.
After several struggles as well with the easy-installer as with the step-by-step installation (both broke down or interrupted the process at some point) I wonder if I cose the wrong version by trying “IMG-e-1.2-q-20220728206708-dev-FP3.zip”.
Do I have to downgrade my Android first? Or is there any easier option?
You might already know, but this is an Android 10 version (the letter Q indicates that).
In your scenario, if you definitely want to switch to /e/ now, go for the Android 11 beta. /e/OS Android 10 has been in beta until just 2-3 months ago, and I have used that beta for months and months before and found it completely usable (even though I was even on the dev-version). I think @Volker has been using the FP2 /e/OS beta for much longer.
Yes, although I will admit I still haven’t upgraded to it myself (I’m using /e/OS Android 10 dev) given I expect an OTA upgrade some time towards the end of the year (hopefully ).
In doubt, trust @Volker who is our main /e/ expert here.
Are you sure that unlocking the bootloader had worked?
Do you have an error message you got after typing in the fastboot command?
EDIT: Rereading about your problems (and that easy installer did not detect device): when you start the fastboot mode of your FP3 and type in fastboot devices do you get a device-ID back? Are you using a USB data cable (is data transfer between your PC and the FP3 possible)?
Are you trying to install from a Windows PC or Linux? It might be a driver problem if device access is not possible.
I use Windows 10. In the Explorer I find the FP3 as drive.
Yes, bootloader is unlocked. fastboot devices fails.
!UPDATE: No, sorry it works! Device-ID is transmitted
The Error messages at the installation are different.
a) Sometimes “wating for device” (although I checked USB-Transfer)
b) sometimes reading error
c) sometimes writing error
OMG! I think I got it!
I’m afraid I never went back to the fastboot mode after unlocking it i nthe first place. That way I tried to install the new OS while running Android. How embarassing! But now it seems to work out.
Yes, thank you very much.
As you suggested above I habe chosen the Beta version (Andr. R) now
).
