Most V90 problems come down to the microSD or a flaky image. If it hangs on a logo or shows a black screen, re-seat the card and, if needed, re-flash a fresh image with Rufus or Win32 Disk Imager. For controls, audio or save issues, check RetroArch input mapping and the OS settings. Because the V90 has no Wi-Fi, ignore any online-update prompts; recovery is always a re-flash. Charging trouble is usually a weak USB-C cable or charger.

FAQ

The V90 shows a logo then freezes. What now?
Power off, re-seat the microSD, and power on. If it still freezes, re-flash the card with a fresh image using Rufus or Win32 Disk Imager.
Sound or buttons are wrong in games.
Open RetroArch's input menu to remap controls and check the OS audio settings; a fresh re-flash also clears bad configs if the problem persists.
