Quick answer

re-flash microSD with latest image·(tools: Rufus/Win32DiskImager)(tools: Rufus/Win32DiskImager)

Steps

  1. 1The V90 (RK3326 clamshell) runs its open-source Linux OS from a microSD, so updating means writing a newer image, not patching a locked ROM.
  2. 2Back up your saves first; re-flashing erases everything on the card.
  3. 3Download the latest image for your OS (stock V90 image, or a community OS that lists the V90) from its source page.
  4. 4Clear the card with SD Card Formatter, then write the image with Rufus or Win32 Disk Imager.
  5. 5After writing, extend the main partition to fill the card if your image needs it, then boot the V90.

The Powkiddy V90 is an RK3326 clamshell with no locked vendor firmware: its OS lives on a microSD, so a firmware update is really an OS re-flash. Back up saves, format the card, and write the newest image with Rufus or Win32 Disk Imager. The original V90 stock firmware image is preserved on the Internet Archive if you ever need to return to it. Some images need the main partition extended after writing before all space is usable.

FAQ

Does the V90 update over Wi-Fi?
The original V90 has no Wi-Fi, so updates are done by writing a newer microSD image on a PC rather than an over-the-air update.
Where do I get the stock image again?
A copy of the Powkiddy V90 stock firmware is archived on the Internet Archive, so you can always re-flash back to the factory OS.
