smssms Posted July 28, 2019 Report Share Posted July 28, 2019 Hi Does anyone have an Europe F940BT backup they can send me as my system has died after trying to perform the "AVIC-F940BT_FW-Update_v4.600". When I performed the update I did the following; Began with - AVICZ110 (folder)and TESTMODE.key System Comm Write - SD 8.05 System stated - Processed and Completed Then System stated - Erasing - Completed cs err Screen stayed in "test mode" for about 1 hour then shut down by itself. My system will not reboot and now has a black screen only with no lights to the controls as well. Has any one else had this problem? Any suggestions? and please the procedure to upload the files to my stereo Thanks Quote Link to post Share on other sites
