Last night I downloaded Blazingwolf 8-20 mod version, unable to use pd launcher. BW reviewed his Novel no problems encountered. Today I tried again, still get pd launcher failure. reverted back to BW 8-6 mod version no problems.Do you see any problems with the 8-20 mod? This is the first failure I have with all the mods since the beginning of ownership.I know in one of your post your stated to remove the userdata.img file from the zip, others suggested that you must also change the checksum.Could you tell me the actual process: Do I just open the zip file and delete userdata.img or something else has to be done?If I download the latest firmware update from PD and remove the file will I keep the hack in place, a lot of questions, thanks in advance
