Right now I have in my phone the stock rom and I haven't rooted it. I want to root it and change the rom.
- What should I do first, root or flash the rom?
- I don't want to lose all the configuration, apps, apps data or files (images, music, videos, etc in the SD). How can I do to be sure to avoid this?
- I want to make sure I can go back to the stock rom if I need, is there any special thing I should do?
If its relevant, I have a Samsung Galaxy I5510.
