I loaded the 21 version of this ROM coming from ver 11 so it's been a while since I've flashed anything to it. Everything was working fine except the Wifi. The compatibility pack installed for me but it prevented the ROM from loading. I tried another stock kernel I found in XDA somewhere just to try (don't remember which exactly). The ROM did not load and the Ext SD card stopped reading even in recovery, so clearly that didn't work XD
I followed the suggestion of
others who tried the Boeffla (my experience
here) and now everything is working
beautifully. Learned how to create my own odin flashable(s) through the experience so a lesson worth learned.
Great battery life, zippy, fast, clean experience... I will have a better idea of performance once I get everything loaded back up. I had quite a few apps before. Happy to be up and running since this is the tablet I mainly use when I meet with clients.
