[1.1.2 OTB HW Unlock] If i encounter problems after ienew, what options do i have ?

Hi guys,

I am working on doing the HW unlock. I have my iphone and ready to proceed with the ienew command.

I have read about all the tutorials and posts about the HW unlock, but i just would like to validate the following point. After executing the ienew command if i am unable to do the next step iunew for some reasons, what would be my options ? Will i be completely screwed and my iphone bricked or is there any workaround to this ?

Thanks for your reply,
