Thanks for trying, n thanks God if your C550 is still usable after that!
Looks like it won't be necessary to know more about what this chinese website says. I got interested after seeing the several smileys in the forum there, but it must have been people laughing.
As for mine, it is still being buggy, that is while placing a call it happens that the phone gets entirely stuck and that it is necessary to take the battery off. It's very irritating, knowing the call can not be stopped. I have the original Orange' rom, and wonder if another rom, such as qtek or imate's would improve the stability... Any advice appreciated.
