I used a Raspberry Pi on my device to install TWRP , since it supports most things , like ADB , without needing to install extra drivers and stuff . It ' s a PC , but a $ 35 PC . You can also buy a touchscreen for the display port for around $ 60 $ 100 . just a couple options <| sep |> all the hugs <| sep |> Sorry , I forgot to reply . To add the sounds manually go to the first frame that the action starts and place the sound file . Where the weapon first has an orange fire burst thing at the end is when you add the sound , do this for the entire spray until there is no more . Similarly when you switch to a new weapon , add the sound at the beginning when the weapon first appears on the bottom of your screen . I ' ll try to upload a video explaining it more in detail in the next few days
