For anyone who's dealt with their radio boot-looping/blank screen/SD card unreadable errors and then sent in their radio to a repair service, I have some questions:

• Which service/company did you use?
• If your radio is still functioning, how long has it been working since the repair was completed?

I'm trying to see if there's one service that has successfully, permanently repaired these radios, but for the forum posts and YouTube comments I've seen on the subject, those people who've sent in their radios for repair initially had success, but within a few months to a year the problem returned...
