some users are reporting this issue. some are reporting everything is working fine. i have a feeling it has to do with the emmc not being wiped. you need to find away to wipe eemc. this is were book marks and such are stored.
I have been trying to use your Kaos_Hybrid_4.20_V4.zip but once i install it and go and download any apps the screen goes blank. Now i've tried downloading the file again, full wipe and at the end i get the same result. Any ideas of what may be going on or something i am missing? I am using TWRP and now using ViperRom. I want to use yours though, let me know if you can help.......Thank you!
