Debranding w910i

I bought an Orange w910i unlocked. Currently using it in the Asia. It is still branded with Orange.

I Want to debrand the phone to the generic w910i formware. I've read a lot of posts and forums but all conversations seem to be between experienced users who know terminology. Is there's a beginner's guide to what the different terms mean?

I have no idea what is DB2000 or DB2020 of DB3150 is. Is this some operating system version?

What is w910i? DB3150 or DB2000? How do I check?

What's GID? Something to do with the firmware or platform? Why is it importnat?

How can I check what the latest firmware for my phone is? Where can I get the latest version of the firmware for my phone? Does SEUS provide? How do I get it?

There seems to be a paid website (DavinciTeam) that offers debranding. But it looks like it can be done for free with XS++ too. But again, the instructions are a little advanced so a little beginner's help would be really appreciated. Is XS++ the only way to do it? Does it work on all SE phones? How can one check what it supports?

Anything else I need to know?

Thanks

You can`t debrand it for free, because it`s a new platform and the program ( xs++ or setool lite doesn`t support it - only detect it. )

Nice day

DavinciTeam - Welcome on our Site.....
you have to pay but there is no free solution

Someone said that even though its unlocked now, if i debrand it, i will have to unlock is again because it will become locked. Is that correct?

W910 and K850 hasn't got a patch unlock. If you have got unlocked W910 or K850 - after flashing it will be still unlocked

One more question... can you please point me to news sources (websites, forums/threads) that I should be monitoring to find out when a new version of XS++ is available so that when it is, i can use it to debrand my w910i.

Thanks.
