I have a Zopo ZP700 and am using CM13. I have tried all the different ROMs available but all have the same problem:
When I opt to format the sd card as internal, it says that the card (a class 10 micro sd card from sandisk that works ok elsewhere) is too slow and after finishing, says that it's corrupted.
I tried the following using ADB but no joy and I'm getting no feedback from the devs so coming here as a last resort:
sm partition disk:179_96 private
gives no errors but the card still shows as been corrupted.
