[Q] Revert to SONY Official ROM

---

Hi. I did use search but the similar threads were about other phones.

So, ive installed this rom kX10 R2B001 - 03FEB11, from here
and ive had some problems getting the stock backup & restore to work. There were some threads about that but none was conclusive, and now am left with a fast x10 and no data to restore. My option at this point is find a backuper that can read the file i created or go stock, backup using some other thing and then go custom.

So, i know i can, my question is : how exactly do i go from a custom ROM to a stock one? am using a 2.1 Xperia X10i

Use Sony Ericsson PC companion and use the repair function gets you to stock firmware.
