Hi redditors!
I've been a 2.15 user with DDVK hack for some time now, and my experience has been great so far. New rm-hacks repo and 3.8 native features are tempting though.
I wanted to test the upgrade while beeing able to revert to 2.15 in case I don't like the new experience. I know the switch.sh script. My issue is the following : in 2.15, the only version I can update to seems to be 3.04, and not directly 3.8. However, if the update goes in two steps (2.15 -> 3.04, then 3.04 -> 3.8), I believe the 2.15 partition will be wiped by the two steps process, am I correct ? Then, how to upgrade to 3.8 and keeping the ability to revert back ?
Thanks for your help

Edit : Currently, one partition is on 2.15, the other one in 3.3
Actually this is the issue. New firmware is always written to the inactive partition. Thus, if I update from 3.3, it will overwrite the 2.15 inactive partition with the new 3.8. The solution have been given by rmhack : using RCU, you can upload a firmware to the inactive partition.
