XS++ 3.1 Guide-Flashing, Customizing, Recovering

[humayunl]

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
