I downloaded Blazingwolf light modded firmware, after installation tried switching to PD home screen using Home Switcher, received an error application failed, try again or reboot that didn't work reverted back to BW 8-6 version no problems encountered. Is sometime not just right with 8-20 modded version? Also need some clarification: if the forum moves mainly to firmware 2.1... When new versions of the software are released from Pandigital. Do I just open the zip file and delete userdata.img or do I have to also change sometime in the checksum. The reason I am asking this is because of conflicting post on the forum. Thank you for all your help.
