However, when I start the process, it fails (unknown error). I am told that I need to use the "correct" RUU and try again. My problem is that the one I am using claims to be correct. Sprint_HTD_One_m7wls_1.29651.10_RUU.zip
I have noticed that when I am going through the RUU process I am shown the screen that asks to compare the current version with the new one. The current image version is blank. Nothing there. No current image version at all.
