I updated the firmware to 3.5 of a mk2, and now everytime it boots, goes to the logo. I have to press the top left button with a reset to be able to boot correctly, and then, choose the preset I want.
I tried to re-upload the firmware, but this happens with 3.4 too!
As a note, on MacOS 13.4 (ventura) there is no unmounting the E1 drive, it just does not want to unmount!
Can you post the preset?
It happens with any preset! Actually, a selecting my blank slot 1 freezes the electra.
Is there any way to completely clean install the Electra mk2?
This is driving me mad. Even if there is no preset at all, and I delete all, it just freezes. I think the preset handling aspect is causing the crash. I really need to completely wipe all the presets, even the empty ones.
I never imagined anybody would write 4000+ lines Lua module for E1 
Impressive and exciting! The issue is dealt on PM.
This has been Solved. Thanks Martin!
For reference:
And this way, it was not refreshing anything ever again.
Thanks for posting the solution with the top left button!
I had the same problem, and the trick with pressing top left button at reset helped me.
I have not found this trick in the documentation, actually it has no section for problems/solutions or similar.
It could probably be documented somewere in the docs then just in the forum - maybe the documentation and/or the FAQ could have a list with troubleshooting / rescue commands.
That would have saved my trying to reset/reinstall the 3.5 Firmware 5 times
It’s 25k lines now! However, Im coding stuff on the computer to avoid the back and forth to the E1 reset-mounting drive-reset to use code as proper lua modules. Hopefully soon there is a way to upload modules into the drive.
