I'm trying to set up a recovery file as a starting point before flashing my dx. I have downloaded RSD lite and two different sbf files. I'm looking for a way to save my current phone version somewhere in my laptop hard drive before I start flashing my phone. Please point me in the right direction. I'm unsure about what sbf files I should use as a back up for my phone.
I have read that corrupt sbf files may lead to a bricked phone. I have came across MD5sum while reading a thread and have no idea how it works. What is the best way to have a solid foundation before I attempt to root my phone? Thanks
