Herelink wifi not working and firmware update

Hi Guys,

I got my herelink unboxed and connected and paired radio and made calibration etc. I noticed that wifi isn’t detecting any network at all! Tried many times but failed. I decided to update the firmware but that resulted in a failure, then I said why not resetting the herelink to factory setting and start fresh but that resulted to another failure because the herelink launcher stopped working and main page is flashing and not stable and I could not do any thing! Tried to flash firmware several times but nothing happend and I also corrected the time & date & region but nothing happened.

Wifi is not working at all. Kindly help please
