Has anyone successfully downgraded from 3.27 to a Toltec-supported 3.3.x build recently?

Before I pay for RCU or start hunting down signed firmware files, I wanted to ask the community directly.

Device: reMarkable 2
Current OS: 3.27.x

Has anyone here successfully downgraded from 3.27 to any of the 3.3.x builds in the last few weeks?

I'm particularly interested in:

• Whether the downgrade actually completes without bricking or semi-bricking the device
• Whether notebooks / annotated PDFs remain readable afterward (i.e. no silent data loss from file format changes between versions)

If the general experience is "not really possible anymore" or "only works with some data loss or heavy manual intervention," I'll probably just wait until Toltec has solid support for 3.27 rather than risk the device.

Any recent first-hand experiences or pointers to up-to-date guides would be very welcome. Thanks!

I have not had anybody report back that anything has changed about this process, and the same warnings about file formats apply.

Have you looked into reManager and vellum instead?

Thanks very much for the quick response! The file format warning is exactly what concerned me most — good to know the process itself hasn't changed.

I hadn't looked seriously at reManager/vellum — I'll explore those. Do you know if vellum currently supports 3.27.x, or is it only confirmed up to 3.26? That would make the decision easy

As this is the Toltec discussion forum, we can't really answer vellum related questions here, you should instead ask for support with vellum on vellum related support forums
