Inside TWRP:

Share your experience in the comments below, and if you find a newer build of LineageOS 14.1, let the community know.

While it is technically possible to flash via Linux, the SP Flash Tool (the standard tool for MediaTek devices) is most stable on Windows.

Think of your A3500-HV as a dedicated device. Mount it in your kitchen for recipes. Attach it to your stationary bike for workout streams. Give it to a child with YouTube Kids and parental controls. The custom ROM is the soul transplant this hardware needs.

The only stable “custom” experience is rooted stock ROM with Xposed + debloater.

: Perform a "Factory Reset" wipe (Data, Cache, and Dalvik).

Load the "Scatter-loading" file (found in the stock firmware or TWRP package). Uncheck all partitions except .

Install Kernel Auditor. Under CPU settings, set the governor to Hotplug (if available) or Ondemand . Disable one core at low battery.
