Here is the process you can apply:

Requirements

  • A backup of your phone’s important data on an external storage device (optional, but recommended).
  • A phone with at least 50% charge.
  • A computer with adb installed. How to setup adb?
  • A functional data cable to connect your phone to your computer (A charging only cable won’t work).
  • Download all the files mentioned in the download section.

Downloads

Updating /e/ via recovery

  1. Download the OTA with the hotfix (See downloads section).

  2. Reboot into recovery mode:

    • With the device powered off, long press the Power button and Volume up button together, until a text menu appears on the screen.
    • In this menu, the Volume up button is used to navigate through the options and the Volume down button is used to confirm a selected option. The selected option is indicated by an arrow <<==.
    • Select Recovery Mode using the Volume up button, then use Volume down to confirm the choice.

  3. Sideload the /e/ .zip package:

    • On your phone, select “Apply Update”, then “Apply from ADB” to begin sideload.
    • On your computer, sideload the package using: adb sideload <path to OTA zip file>.

    NOTE: Normally, adb will report Total xfer: 1.00x, but in some cases, even if the process succeeds the output will stop at 47% and report adb: failed to read command: Success. In some cases, it will report adb: failed to read command: No error or adb: failed to read command: Undefined error: 0 which is also fine.

  4. Once you have installed everything successfully, click the back arrow in the top left of the screen or swipe back as the android gesture, then select “Reboot system now”.

Thanks.
