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
You have two real options for doing what you want:
If you're not afraid to use Python or the command line, you could use codexctl to install specific firmware to your tablet. I haven't ever used it myself, so you'll have to read the docs. I don't think it can just flip the boot partition flag so you might still need to rely on switch.sh.
Use a nightly build of RCU, which can flip between boot partitions at-will, and also upload firmware files (with the .signed extension) to the inactive partition. You would right-click on the tablet icon, press Upload Firmware, install the 2.15 one, then do it again for the 3.8 one. To flip between, them, right-click the tablet icon and select Flip Boot Partition.
To download the firmware files, you could either download them using codexctl's CLI, or you could use the URL listed here and combine it with the firmware version numbers and suffixes listed here to get the specific ones you want (pay attention to 'remarkable1' vs 'remarkable2'!).
If you DM me, I'll give you a gratis copy of RCU because I want more people testing this feature.
Ah interesting I’m a RCU user but for some reason thought it only worked with the older software so I haven’t tried it for a while (since my rm upgraded). Also hadn’t heard about rmHacks. What’s the best way to learn about the 3.x offerings? I’ll try out the dev version of RCU asap
