Well. I suppose this means that people who know how to jailbreak hardware and liberate it from its software-imposed limitations are going to be in higher and higher demand. These fucks need to be taught that once they sell a product it's not "their" product anymore.
Doesn't seem it was SolArk that had any part in this but a check in the firmware written by Deye. They claim it's always been there though it is highly suspicious this happened to seemingly multiple people on the same day.
