I just tried the Zarva firmware and a very interesting thing happened.
It caused the bad block error on my player!!.:shock:
The good news is I got it back again by alternately trying to flash between my firmware and ConsumerUpdate and the Zarva firmware a few times!!!:roll:
I found that I had to load the zarva firmware into my Consumerupdate to get it to flash otherwise I got write error.
These Rockchip players are very robust I thought I had killed mine for good but it's back again now!!!
It proves as Daremo says that the bad block problem is not permanent
