The V90 is an RK3326 handheld, and the most clearly supported community OS for this exact model is MiyooCFW, which lists the Powkiddy V90 by name. The broader RK3326 firmwares — ArkOS, AmberELEC and ROCKNIX — target this chip family, but the V90 is not on their official device lists, so verify support before flashing and treat them as unverified for this model. Format the card, write the image with Rufus or Win32 Disk Imager, extend the main partition, and keep your stock card so you can return at any time.

FAQ

Can I run ArkOS or AmberELEC on the V90?
Those firmwares are built for the RK3326 chip but do not list the V90 as an officially supported device. MiyooCFW is the community OS that names the V90, so it is the safer choice unless a project's current list adds the V90.
Will custom firmware brick my V90?
No. The OS lives on the microSD, so flashing only changes the card. Keep your original stock card aside and you can swap back to factory at any time.
