Wii u brick 160-2215 and 160-0103

I have a problem with my wii u I was installing super smash bros for wii u when the download stopped so I made the decision to restart the console and the error code 160-2215 was displayed afterwards several restarts the code became 160-0103 and finally an infinite loading of the wii u logo I read on the internet that a baspberry pi pico could solve the problem so I bought it and I managed to access the recovery menu and get the otp and the seeprom as well as the logs but after changing the title and restarting the console I still have the wii u logo which loads endlessly who can help me?
