Just thought I'd add some info I found out today. I didn't follow the correct unlocking procedure (as per SIMOX) - I didn't understand Setool exactly when it wanted to disconnect battery then reconnect and didn't wait long enough running the patches - read instructions carefully - wait till setool says time elapsed etc.

Anyway I got my phone totally messed up and tried to retrace steps by writing the GDFS backup back to phone - It all got worse till the phone didn't do anything, pressing the power switch nothing but a quick flash of the red light and worse couldn't connect the phone with the USB cable pressing the 'C' key. Removing battery etc no help. Thought maybe EROM was faulty or something.

Started to look at D ultimate unlocker and saw it mentioned pressing 2 and 5 keys together instead of C in some cases so tried this with setool or XS++, can't remember, and hay presto it started to free up an then even pressing C worked again.

Still had all the problems with white screen blinking so reloaded the GDFS, main firmware and custom pack etc to get it working again then went though the unlocking again and still made one mistake but not so big.

Conclusion: try 2 and 5 together if c fails when trying to connect USB cable.
Take extra care when following unlock procedure. More time/cost effective to pay someone who knows how to unlock but I like a challenge on a rainy day.

Great site and thanks to all those clever people who help us with less knowledge (to mess and sort our phones out). Now off to find internet setting for foreign SIMs.
