Powkiddy X28 — Firmware update

Quick answer

Button combo

Power offhold VOL−connect USB-C to PCflash tool

Steps

  1. 1The X28 is an Android 11 device, so firmware is the official Android image flashed from a PC, not a microSD write.
  2. 2Download the latest official X28 firmware package and the Unisoc (Spreadtrum) flash tool from Powkiddy's firmware page.
  3. 3Install the tool's USB drivers on your PC, then load the firmware's .pac (or its XML) in the flash tool.
  4. 4Power the X28 off, hold VOL− and connect it to the PC with USB-C; the tool detects it and flashes.
  5. 5Wait for it to finish and reboot on its own — do not disconnect mid-flash.

The X28 runs Android 11 on a Unisoc Tiger T618, so updating firmware means flashing the official Android image with a PC tool, the same procedure Powkiddy uses for the X18S. Power off, hold VOL− and connect USB-C, then use the Unisoc/Spreadtrum flash tool to write the official firmware package. There is no simple microSD-image update like on Powkiddy's Linux handhelds. Note that Powkiddy's posted download links for X28 firmware have at times gone dead, so if a link fails, contact Powkiddy support for a current copy.

FAQ

Can I update the X28 from a microSD card?
No. Because it is an Android device, the official firmware is flashed from a PC over USB-C with the Unisoc flash tool, not written to a microSD like a Linux handheld.
The official download link is broken.
Powkiddy's X28 firmware links (often OneDrive) have lapsed before. Email Powkiddy support to request the current firmware package and flash tool.
