Hi
I bought a z3 D6653. It has Customized_TW rom in it.
As I live in Japan I went to Docomo to upgrade my current contract to use it.
They made a SIM card, which worked for pone calls but not for data. After checking the phone they showed me that the D6653 does not have the Japanese wireless certification (it has US, EU and not surprisingly Taiwan)
So off course they cancelled the new SIM and I'm back with my old phone.
I checked a lot the forums and other websites and it looks like that by just flashing I could solve the issue. As I'm new to Sony Xperia I have few questions:
- I saw many people saying flashing a D6603 rom on a D6653 works just fine. That would solve the wireless certification issue because the D6603 shows the Japanese one. However I think that unless I flash to the Docomo branded rom (SO-01G, not D6603) I won't be able to use my docomo mail address. Has anyone ever tried this ? Is it safe (the only difference i see on the SO-01G compared to the D6603 is the bigger 32Gb memory and the oneseg TV)
- in flashtool, when creating a bundle, should I choose the original device (D6653) or the device for which the rom I'm trying to flash was created for (D6603 or SO-01G)
- finally in general, how risky is it to flash ? I backed up my original rom the Sony PC companion downloaded (and created an FTF with it). Is there any chance that after an unsuccessful flashing in flashtool I can't revert to it (either using flashtool or the PC companion) ?
Sorry for the newbie questions....any help would be greatly appreciated.
