Hi, everyone,
I just received my MangoH Yellow and am trying to activate it at the Octave site for a few hours without success. After searching through the forum and having tried the solutions mentioned here ([Stuck in Low Power Mode - Image Preference Mismatch - #8 by liborsvehla - Legato Forum](https://forum.legato.io/t/stuck-in-low-power-mode-image-preference-mismatch/2820/8)), I still cannot turn on its radio. Does anyone have any suggestions? Thanks.
