| besides the problem that i have, all the rest if very fine.
i have a s45 and i have done many upgrades of firmware, the last was v23 (the only i found with portuguese language).
Then i upgraded to s45(i) v04 following the instructions you can find in the forum.
As i said the only problem i have is really that the phone doesn't start when is cold.
But you can always (DO IT!!) a full backup of you flash, then you can try in safe. |
