My Libra 2 never came out of boot loop, and now it doesn't take a charge or power on. I think it boot looped itself right into a completely over-drained battery.
I'm chatting with Kobo support. They are clearly busy helping many people with this as they are slow to respond. I told them what happened and they didn't argue. I'm getting a "replacement" of a different model.
Should I scrub the sd card or don't bother? I'll at least remove the personal information I had on there (nickelmenu stuff, background images)
