I suggest highlighting the part of the instructions saying " Enable USB debugging on your device. You can find the instructions here" because i missed it
You should also link to google’s page to install the USB driver
“Installing /e/ from recovery” Should be completely rewritten since it is really different from the GUI
Hello friends, let me first start out by saying this is not a step by step installation guide but rather a roadmap to some of the interesting things I found installing 0.18 R onto a used and freshly factory reset Google Pixel 4a (“sunfish”) with Android 11 already installed.
First of all, in my case the bootloader would not unlock from the device- the option was greyed out completely in Developer Options. And so, I had to use the command line as outlined here.
Success looks like this:
At some point I lost the USB debugging “authorization” between the PC and device as shown below:
If you see it, there’s no cause for alarm- just “reauthorize” the computer connecting to the device.
A general tip for those new to the Android Platform Tools (ADB, etc.) is to put the /e/ recovery and /e/OS image from here in the same directory as the platform tools so that the processes don’t fail since they’re “right next to each other”…
I got the same error as @lefou did in this thread shown below:
– Wiping data…
Formatting /Data…
Formatting /metadata…

Data wipe complete
Since the wipe said it was “complete” I just went forward. Sometimes fortune favors the foolish!
Sideloading the OS for the first time is always for me the time I hold my breath. This time was no different. I followed these instructions:
It quickly got to 47% and then stopped. I waited 4 long minutes for this message:
But I didn’t get it.
Instead, I got this:
Oh no.
Well, in for a penny, in for a pound. At this point, there was no other option that I could think of but to reboot the device and see where I was at.
Surprise! It booted into /e/OS. I’m not exactly sure why!
Hope this post helps anyone else who’s grappling with installing /e/ on a Google Pixel 4a- I will be following up in the thread some thoughts as I use the device over the next few days. There’s already one issue I’ve come across that’s kinda funny and one that’s a bit of annoyance, but this can wait.
Good luck with your install- follow the instructions and remember what I’ve posted here and you should do fine!

i can confirm that
E:can’t send spi message: Try again
Data wipe complete
and
(47%) adb : failed to read command : No error
(47%) adb : failed to read command : Success
are known as successful messages

Hi!
I bought the Google Pixel 4a to install sunfish on it.
Now I read on the documentation page this:
Warning: Downgrading Smartphones already on Android Q or LineageOS 17.x to Pie or other OS can cause instability or at worst brick some devices
The pixel came with Android 11. I really want to install the OS but now Im a little bit skeptical.
You have any ideas?

That warning is out of place for sunfish.
If you are running Android 11 now, you are good to install eOS-r. However, if you have updated to android 12 on your device you will have to flash the google stock rom for android 11 before installing e.
More info here if you need it (and elsewhere in the google devices category 
)

I just want to echo @chrisrg here. If your device is on Android 11, the /e/OS “R” beta MUST be flashed to avoid problems. If your device is on Android 10, you have the OPTION of flashing /e/OS “Q” or updating the device to Android 11 first, and then flashing /e/OS “R”.
Good luck and let us know how things go!

Ugrade to 1.15 T (Android 13!!) just went smoothly.
No hickup. 10 min and done!
Great job!
Did you flash it, as in clean install? If you sideloaded it to eOS already on it, from which version did you move to T?
@Manoj Would it be possible to add documentation how to upgrade from R to T or if it needs to be from R to S and then to T would also be fine. I would like to upgrade my stable R to T dev. I was under the impression I would have all vendor updates for T in the image but I don’tlknow how to proceed. I am aware it is a manual thing but I would prefere not to backup and clean install. If no other option is available, than to go stock to make the device ready, so be it.
I installed (sideloaded) S already some time ago and had some OTA-updates. The latest was e-1.14-s-20230819321663-dev-sunfish when T came out.
I followed the steps in the documentation and everything went smoothly.
