[HOW-TO] Flash /e/-OS on Fairphone 3 using Debian based GNU/Linux

Testing. Updating Nougat to Pie Without Firmware

Note: This is not a tutorial, how-to, or guide. Merely a journey trying to figure out how to easily and simply upgrade the Essential PH-1 from an existing /e/ Nougat ROM to Pi/e/ without losing data, going back to stock, or what have you. Okay, for testing purposes I went all the way back down to stock Nougat firmware. Using last Nougat build from Essential (some of the Nougat back-to-stock builds are no longer available). I edited the flashall.bat a bit. With ‘fastboot -w’ in the first line,…

Updating to /e/OS Pie using fastboot, adb, and TWRP on Essential PH-1

I followed the official installation guide with success. I only changed one command: I replaced fastboot flash boot twrp-3.3.1-1-fajita.img by fastboot boot twrp-3.3.1-1-fajita.img

FYI, I did the installation on a fresh unboxed ONEPLUS A6013 model.

Found here: https://doc.e.foundation/devices/fajita/install

Temporarily flash a recovery on your device by typing:

 fastboot flash boot <recovery_filename>.img

[martoni]

Hello @zero,

When you did this : sudo fastboot boot twrp-3.3.1-1-fajita.img

After, what kind of screen did you have on your phone and what did you do ?

thx

First, it’s strange that you don’t see your device when you type adb devices. I think this is the root cause of your issue…

I don’t remember well but I think that my phone was in fastboot mode. I typed the flashboot boot command and then the phone restarted automaticly recovery mode (with TWRP).

I found !!!

perfect. enjoy eOS

Well done!

What did you change? Only the TWRP image?
If I’m not wrong, you installed TWRP from Android 10 whereas I did from Android 9. This may be the explanation…

[martoni]

Hello,
Yes, with a new twrp.img from another source, and next :

sudo fastboot boot twrp-3.3.1-32-fajita-Q-mauronofrio.img

And, the device (oneplus A6013) reboot with TWRP

Hi @martoni as required have marked the thread as [SOLVED]

[Anissa]

Great, thanks! I had the same problem with my OnePLus 6T. I think the files made the difference, because I first tried with the ones provided one the TWRP website for this phone (Android 10) and it didn’t work, but worked perfectly with the files linked in the article that you provided. Thank you! Still need to install eOS now… Fingers crossed haha.
