Help Me Unbrick
Sprint Galaxy S3. History of the device is, I updated to 4.3 OTA, rooted using saferoot, odin'ed to stock 4.3 to get root, flashed philz, started getting update nag for 4.4 so I followed a guide and installed something in my system directory that blocks it. It seemed to work fine for a bit. Then one day I picked up the phone off my nightstand and it was bricked. I had just checked my email on it a few minutes earlier.
if I put in the battery, the phone autoboots, but all i get is the Samsung logo for about a second and then it shuts down, completely dead (buttons don't do anything) until I remove the battery again and reset the device by hold power for a few seconds with no battery inserted.
My class 10 samsung 16 GB SD card that was in the phone seems to be dead now too, I couldn't read anything when I put it in another computer.
I can boot into philz recovery by holding power, vol up, and home button, while sliding in the battery.
I can't boot into download mode using this method. After holding power, vol down, and home button while sliding in the batter, it attempts to go to download mode, but again shuts down dead like what happens on a normal boot.
I got the usb jig and it doesn't help me at all.
I got another 16GB class 10 SD and tried this method: http://forum.xda-developers.com/show...&highlight=4+3
using the debrick image from here: http://forum.xda-developers.com/show....php?t=2637424
and that doesn't seem to work. Putting in the debrick SD card seems to make no difference.
Is there a way to use philz to recover my phone? Is there a different debrick image that would work better for me?
