3G not working after ICS downgrade
Hi guys. I live in Greece and I have a beautiful Samsung SII GT-i9100 which I bought online and did not receive with any strings attached. About 2 motnhs ago I upgraded to ICS; it looked like a logical decision at the time, but it went south pretty fast.
The phone ate away at the battery and it lagged horrendously, something my 2-core phone never did before. Very often it would hang needing a hard restart (take out battery) or even restart itself. I spent about a month trying to cope and because I didn't know how to reverse it.
But I coulldn't cope any more so I decided to downgrade (but not to ROOT, I'm still in unsure whether I understand enough). I read up on it and it soon became clear it was doable.
The hard part was getting the right ROMs (and it still is). I looked for 'the right' kind of Gingerbread but to no avail; most links were either dead or a trap (admiralackbar . jpg). Finally I struck on some promising ROMs (3 in number, of which 2 work for me).
I used Odin3_v1.3 and flashed my phone with:
1. GT-I9100_INU_I9100XWKL1_I9100ODDKL1_I9100DDKL1.tar.md 5, and
2. GT-I9100_ORS_I9100XWKJ1_I9100OXXKJ1_I9100XXKI4.tar.md 5 .
Both worked fine and I thank my lucky stars my phone is up and running again, just like before.
Only thing I can't seem to resolve is that 3G/GPRS stopped working. I called the phone company (WIND HELLAS S.A.) and they said that everything was OK on their part.
I tick the 'User Packet Data' box which used to bring up the 3G/GPRS icon (sooner or later) and provided said conectivity. Now, nothing. Any ideas or opinions more then welcome. Also questions!
Could be some app blocking it?
Downgraded Galaxy SII form ICS to Gingerbread and now 3g/GPRS won't work. Halp!
