I have also tried all that and no luck. The funny thing is that I have barely used the phone in years as I had my earpiece damaged, I live in south America now and since i bought it last year, I have not been able to install it. Therefore, not used it.
It is also interestingly frustrating that this phone, in which I had so much faith, has turned out to be the worse phone I have ever had. The case which was replaced for free (thank you team) decided to break again, unstick from the sides, sitting in the drawer.
I came to get the dust out of it and use it at least as a tethering device, even if I could not use it in its full form,… to find out that it keeps rebooting itself continuosly. I bought two batteries last year too… so it is very frustrating that the most expensive phone I have ever had, because I believed in the company´s values, has become so disappointing in practice. However I still think it is a great concept. Maybe I had the bad luck to have the worst piece from factory. I have spent too much money in parts and repair so far, and not even been able to use it for three months in a row perhaps…
The curious thing is that my most favourite phone ever has been the FP1U which I currently use and has been the most loyal little thing I´ve known, such a great little thang… I managed to adapt a battery HB5N1H with a bit of rubber at the bottom and i cut a little corner for the battery to fit at the top and I was able to overcome the problem that no more batteries were ever available for this amazing little thing.
So,… totally unhappy about the FP2 and totally impressed by the FP1U, which is still my best tool after so many years and overriding the FP2 by far!
TBH FP Team, I dont know what to do abou this device. I am ever so frustrated, you must know from all my previous communications. Please could you provide me with a solution? Thank you!
