we are currently facing a problem when trying to downgrade a P1 from 1.5.0 to 1.4.4 (or lower) via CLI OTA. It results in an error “Update failed - File was too big!”. It is the original release file from github with size of 253KB. Flashing our firmware bins worked fine.
We did this downgrade several times before on other P1s and never saw this problem.
Does anyone have any idea how to solve this issue?
