I have a One 3rd gen which has developed a peculiar problem. It will work ONLY once after the battery has been allowed to go flat and it's been recharged. Once it's been charged I just get "waiting for a valid GPS signal" and a grey screen. I've done the WNRO bug fix and tried it again today. It worked one way and then just left me with a grey screen. Doesn't seem to matter what I do. It is becoming very frustrating.
I don't want to hear the "legacy device" argument - I really just want to use it again.
Thanks in advance.
