[Q] Return Unlocked phone for repair
My Sprint HTC One will not be recognized by any PC. It is unlocked. I have tried it S-On and S-Off. I have tried multiple cords, on multiple USB ports, on multiple ROMs, on multiple PCs Win 8, and Win 7. I've installed universal drivers and the uninstalled HTC Sync. I took it to the Sprint Store and the tech thought he fixed it by putting the phone in USB debugging mode. That didn't work. HTC said to reset the battery stats by powering down for ten minutes, then hold vol up, vol down, and power for two minutes. No luck...
I am able to to use dropbox to load ROMs and backup files.
I reached out to HTC again to troubleshoot. My question is, will i encounter problems if i send the phone unlocked and on a custom ROM to repair a USB port? The warranty language mentioned service fees and handling fees. I don't wish to encounter these. lol. I would love to send it back with factory setting, but cannot without a working USB port and a PC. Right? Any suggestions?
