Hi guys. I have a similar problem. I have Hive on my smartphone , which was broken six months ago; Today I repaired it and I read that HIVE is closed and it is no longer supported !!! I do not remember my passphrase , but I remember my PIN ... but when trying to enter... it remains stationary on "Verifying your PIN".
How can I fix it?!

thanks for support!
I don't think the PIN is enough to recover your coins with another wallet, like Mycelium. But the passphrase or private keys *might* be recoverable from your phone. I personally don't know how to do it. Perhaps someone else can help you.
