Have I bricked my Phonak Aid?

Yes, you can try using Phonak 7.0.7 (like the airplane). Though, we don’t actually know which combination of (Target fitting software & iCubeII) is best for avoiding the bricking of your hearing aids. We only know which combination (Target 6.2 & iCubeII) was successful in performing a factory reset/A.K.A unbricking the hearing aids.
