@brinerustle was able to provide a download of LunarOS. I was able to install it, then was able to successfully flash my IMEI back to the phone. Now back on iodéOS again with IMEI in place!
@plamen I know you are busy but I would recommend giving a big warning on the SP Flash guide on the how to upgrade your brax3 post to NOT use the “Format ALL + Download” if you are installing / updating iodéOS since it isn’t possible to re-insert your IMEI afterward.
