Well after finally deciding to upgrade the firmware of my Helix 10 di gps, reading the instructions, and following them as directed. IT, Technician and programmer for over 4 decades ya figure wit would just go as normal. Nope, it decided to restart on its own and then go into a boot loop. HB customer service, and HB tech reps (no techs so far) basically gave me the same song and dance politely… send in with $240 and we will fix it. I check the web and there are tons of people with the same issue. No I wont be spending $248 on a unit because either their process is bugged or their rom is buggy. HB people are nice, and even nicer at denying issues. I will however figure out the boot loader access and or re burning a new rom and replacing the current one… looking for those forbidden schematics now and into the os programming…
