I have the HTC Inspire 4g and haven't used it in about a year. It sat on a shelf and waited for me to come back to it. Well i turned it on was going to update it via wifi. I tried turning it on and it would say "turning on..." after a few seconds I get the "error." I do not have cell service until I get the sim card from straight talk and I can't connect via wifi so I really just have a phone that doesn't do squat at the moment. I have tried all remedies except that they all require a connection of some sort to make an attempt to fix this... The only one I tried successfully that didn't work was clearing the cach via the boot screen menus. It did not work. I tried the *#*#526 thing as well but it just deletes the number after I add the last character. I just updated to the latest software via HTC's website... Don't ask me if I'm rooted or flashed or whatever, I don't understand any of that mumbo jumbo except I think I did root it when I first got it but it has since been been reset to factory settings and it deleted everything when I updated it.... Here's my info: Android Version: 2.3.5 HTC Sense Version: 3.0 Software Number: 3.20.502.52 710RD Kernal Version: 184.108.40.206-ga375925 htc-kernal@u1800-build-144 #1 Hopefully thats all you need. Thanks for ANY HELP!! It is greatly appreciated!!
