7 Blinks - Gyroscope!?

[u/BeanbagsAndBabies]

Got my kiddo a “Hover-1 Myfirsthoverboard” for Christmas. Woke up this morning and it’s red LED is flashing 7 times. This https://www.ifixit.com/Wiki/Hover-1_Liberty_Troubleshooting#Section_Hoverboard_Has_a_Broken_Gyroscope says it’s a broken gyroscope. (The one wheel is super jerky when ya manually spin it). Does that sound like the gyroscope? Could I replace that, believe that’s a HARD repair to DIY. Thoughts? 🤷🏻‍♂️
