My Photon has done the same thing! I rooted her and did the Bootstrap Recovery
thing. Everything was kosher until I tried to load that stupid Beats Audio. Something happened between me flashing it and the reboot where it locks the phone. I tried to do the Android recovery screen, I wiped, I did about everything I could find. No bueno.
I followed this forum and clicked the software and tools
link as instructed. I tried with RSD 5.6, and tried several iterations of SBF's located here
. I was using SBF - 1FF-sunfire-user-2.3.4-4.5.1A-1_SUN-154_MR-3-CM.
It lets me go into boot mode, and when I try to flash the SBF it appears to go through, but it always fails at the end. Which, the posts state it will do, but my phone will not reboot afterwords. After trying everything I could for a couple days, I decided to just take it to a Sprint store. Mind you I've had this under 30 days, but longer than 14 so they stated it would have to be replaced. They tried to flash, but said they were getting stuck too.
I know that a replacement is pretty much the answer, but just wanted to check one more time to see if anyone had any other ideas, or could point me to other forums maybe? Appears I've done what few have been able to accomplish...brick this joker.
