Wireless car connectivity fails to initialize or randomly disconnects while driving. 💾 Preparation: Finding the Right Firmware Files

You must flash a different version of the K2001N NWD package. Check the production year on your motherboard sticker (often marked as K2101_G or similar) to match the appropriate build archive.

Clear the cache in Settings or re-flash the latest firmware to fix corrupted system files.

This is the most common cause of failed updates. If you flash a firmware intended for a larger screen, you will lose part of your display and the touch inputs will be misaligned. Conversely, flashing a smaller resolution will result in a shrunken image with a black border.
