Yes, there are, for example the following bit that I am copy pasting from another forum:
TT GO 530 Bluetooth Problem
GO 530, NC 9.058, bootloader 5.5128, UK & ROI 865.3245.
If I switch on as normal bluetooth won't connect to my phone (Blackberry 8900). bluetooth is enabled. If I switch off by pressing the reset button and then re-start, bluetooth connects and works OK until I switch off by pressing the top button - if I start normally again bluetooth wont connect again - I have to reset every time.
Tried clearflash, BTON in the setconfig.text file but this does nothing.
Have the same problem with NC 9.024, 9.101 and another which I can't remember.
I have to reset the clock every time I do a hard reset.
The hardware is OK as bluetooth connects perfectly every time using NC 9.004 but I prefer the look of the menus in 9.058 (I think its the x40 style menus I prefer).
1. Is there a way around this problem so that I can keep using 9.058?
2. Can the menus of 9.004 be made to look like 9.058?
3. Is ther another NC I should try?
