Request for Older PrimeOS Version (Rollback Needed for Primebook-WiFi)

Troubleshooting & Support

Post:

Hello Team and Community,

I am using a Primebook-WiFi model and recently updated to PrimeOS Version 2.4.4-ARM (Android 11).
After the update, I started facing multiple issues:

  • Auto reboots
  • Keyboard and mouse disconnecting randomly
  • Inbuilt camera not connecting
  • Input current disconnecting while charging
  • System freezing during usage
  • HAL-related failures (many users reported similar issues)

Because of these problems, I need to roll back to the previous stable PrimeOS version that originally shipped with my device.

Here are my device details:

  • Model: Primebook-WiFi
  • Serial Number: PBO5001708
  • PrimeOS Version (current): 2.4.4-ARM
  • Android Version: 11
  • Kernel: 4.14.186
  • Custom Build Version: alps-mp-r0.mp1-V8.382
  • Build Date: Wed May 7, 2025
  • Build Number: Primebook-WiFi 001.01.00.14

I kindly request:

  1. Official download link for the older stable firmware / OS build for Primebook-WiFi.
  2. Rollback instructions for installing the previous version using USB flashing or recovery.
  3. Any guidance to restore HAL functionalities correctly.

I already raised tickets:

  • Ticket #7082951
  • Ticket #7083004

Please help me with the correct files or procedure.
This is urgent because the device is unstable and affecting my work.

Thank you.
