Here 3+ firmware damaged!

Hi @philip & @Michael_Oborne ,
Actually I have purchased Here 3 + few months ago but now I’m facing some issues in the product. Recently I have tried to update the firmware as per cubepilot forum but after that GPS is not active. Everytime I try to connect it shows “White solid lights”. I have checked on the forum and they have mentioned that I need to update the GPS again through SCLAN mode but I even I cannot connect that mode or GPS. Please let me know if there is a solution for this.
