  @fazullahkharoti:disqus you can change the language on startup. Those images are collected from other source actually. Just flash the firmware and chose your desired language :) Good Luck

  @abdullhai:disqus you may see errors if you release the key once flashing is started. So, keep it pressed to avoid any issues.
