Hello friends!
I received the LG290P and want to use it in challenging environments. I live in Kazakhstan, Kostanay region, next to Russia. And we have a lot of interference here 
When working with the LG290P, I encountered a problem: when the module determines a solution, it writes that it is not serviced. As I understand it, these are sanctions on Russia, but I’m in Kazakhstan.
How to solve this? Maybe there are firmware without blocking or unlock my module by serial number?
With respect and hope, Batyr.
