Error code 105-3035

First timer here, sorry for my English.

I ve got a Wii U Basic Set 8gb, and 've bought from the Eshop, Metroid Prime Trilogy.

I've got this message after the download

Error code 105-3035

1) 5.3.2

2) WUP 001 (02)

3) GW100122213

4) HASB-0210-7375

It says that my unit is read-only, but I could move files from my console to the usb disk.

I have an external hard drive, powered by an Y cable, and played lot of games through it (Arkham Origins, Super Mario World, etc). Never have a problem with it.

Wasn't able to find the error in any site, any idea?

The console is updated, even tried redowonloading the game, but still doesn't work

thanks a lot
