VIM4 Android Recovery for sideloading an OTA upgrade

VIM4
1

Which system do you use? Android, Ubuntu, OOWOW or others?

Android 11 and 14

Please describe your issue below:

Expected:

  1. $ adb reboot recovery
  2. select Apply update from ADB from Android Recovery menu
  3. $ adb sideload <ota-upgrade.zip>
  4. OTA upgrade completes without OTA server

Android 11:

  • $ adb reboot recovery presents the “Android Recovery” menu.
  • But I cannot use any of the physical buttons on VIM4 to move around in the menu and select the correct menu item.

Android 14:

  • $ adb reboot recovery presents a black screen, i.e. no “Android Recovery” menu
  • $ adb devices lists the USB device as in “recovery” mode.

Please advise on how to enable sideloading of OTA binary on VIM4 without an actual OTA server

You can upgrade the OTA package by following the steps below.
(1) Place the OTA package in the/sdcard/directory
(2)Settigs->Khadas settings->Updater->UPDATE LOCAL。

Thanks, yes “Updater” application with OTA file stored on USB memory stick works in both Android 11 and Android14.

I am exploring other options in case the OS does not start properly. Is the “Android Recovery” function supposed to work in Android 11 and Android 14?

@xavier ，
You can burn it through a USB cable. We are not sure if the upgrade using recover mode is currently supported.
