absolem, Dec 13, 2015 : Ive been trying to downgrade from cm13 to the last KitKat COS as listed here. However during the flash process I get an error right at the start - anyone knows what causes this problem? Heres what I did: Wiped System, Data, Cache, DCache, tried to install the respective flashable zip. I doublechecked the md5 sums with the file - its the same. Any ideas?
