last twrp is 2.8.6.0
pa_gapps is allways functional (choose pico to start but stock is ok)
to install you need partial wipes: cache & dalwick cache
important what is you tablet
regards
I have updated TWRP to 2.8.6.0.
After that I have tried to install pa_gapps which is for the version 5.1 so I got some errors while installing.
I had a closer look at the package I previously downloaded.
I have noticed that I have downloaded the wrong version gapps-lpmr1 instead of gapps-lp.
I was then able to start the tablet without any errors.
Thanks a lot,
