it probably won't brick the device but this answer does not correspond with what the dev said. he said .85 is for PBs and .86 for 9.0 OOS
hence be careful and consider the possible culprit if something goes wrong. further report back after a while without issues, also worth to know
if that's so
Let me transcribe that statement.
.85v2 were made using sources from OB3
and .86 - using stable release sources - updated sources, so it should work with both OB and Stable channel, and even more of that, with old 8.1 ROMs
