Hi Deltadroid, after 1.5 months I will give the ROMS another try and hope that the "blank screen" und rebooting issue is not bothering me anymore. I was sick of clean install an reconfiguring every 2nd day ^^
My question is: I am on 4.2.2 bootloader and TWRP 2.8.5.0. Which Recovery should I use and what means "bumped"? Did I miss somehting in the last weeks. Read 12 and 12.1 Threads but were not able to find the answer. Any other changes also? Thanks in advance and still your work is awesome! Thanks for keeping our device alive!
Edit: Couldn't wait

so took your v500-CWM-6.0.5.1 bumped and your GAPPS from here
http://forum.xda-developers.com/android/software/app-minimal-gapps-gapps-lp-20150107-1-t2997368 and the ROM froM CM Site. Now I hope, while I take everything from one hand, that I can use my tablet again
