Personally..I want to say THANK YOU, THANK YOU, THANK YOU.
I have spent the last four hours searching for this. This needs to be stickied. I'm bookmarking it for sure. This got my phone unbricked..I thought all hope was lost and I would have to call in for warranty support (I got mine refurbed through Sprint last October..so I don't even know if I would still have any warranty support), and see if I could try my luck and getting it replaced, since that is what others have said to do as apparently this file from OP, did not exist.
And so for future reference, so that others don't go mindlessly searching through the forums.
a.) Managed to overwrite your Recovery some how or completely delete it. (I did..and from searching this and many other forums over the past couple hours..I can see I wasn't the only one), and also have no boot (or a corrupted boot loop)
b.) Still have S-ON (You can find this out by powering off your phone and then pressing and holding the power button and the lower volume button), I recommend you turn S-Off for future reference if you're going to be dealing with customer ROMs a lot (so you don't have to go through the hell I just did..). See here..
c.) Have an updated Hboot (1.47) (you can also find this info. in part b.)
....then you KNOW that you are stuck. Because you
a.) Cannot flash a ROM in Recovery because you cannot access it.
b.) You cannot access ADB because your phone won't go that far and will only go into fastboot..
c.) But even though you have access to fastboot you can't do ANYTHING like flash a recovery image or a ROM..or anything for that matter..because S is still ON. (this is the "not allow" messages you will see pop up.)
d.) You have bootloader 1.47 so if you for example, were like me couldn't use this file here.. (http://forum.xda-developers.com/showthread.php?t=657086
), because it would say there was a newer version and wouldn't install it.
So this file right here..was the only thing getting my phone back to a usable state. And considering that my searches have shown to pretty much give up all hope and have it sent it for warranty repair, then I think this thread deserves a bump for all those that have screwed up.
Yeah..I have to start ALL OVER now from a stock ROM (thank god for nandroid), but at least my phone isn't a dead brick.
Just thought this needed a well deserved bump.
