So, I'm back with news and apologies for being later than I promised.
I reset to factory default twice and I found these two facts out:
- I've installed a Danish version (though I can switch to any language afterwards - I thank my Germsn for that!) and
- GPRS works after the reset up until I switch on WIFI and connect to a network, afterwards I cannot make come on by any means.
Any opinions or suggestions?
