Hi guys,
I was installing one of the custom ROMs and i dont know what happened after that... the phone is not booting up... not even in Download / Recovery Mode. i tried
1. Removing battery & putting it back in
2. USB Jig method
3. Riff-box JTag...

Nothing helped. Also, the phone heats up unusually when i insert the battery... Finally after lot of research i found that i777 had eMMC issue & probably it is corrupt, so the only option left for me is to replace the Motherboard. I currently stay in India & there are no shops here which can provide me this phone's motherboard.
Almost, for 2 months i hav been taking this phone to different technicians, but no one could repair it. Now i dont know what to do. Please Advise me.... What can i do to bring this phone to life?

What rom were u trying to install? What rom were u coming from? Please make sure u have an i777 and not an i9100 or i727 by taking out the battery and looking underneath. It will show the model number. The emmc brick bug refers to the ics stock kernel having the "mmc cap erase" turned on or something to that affect. It damages the emmc chip doing a factory reset. So unless u have the stock ics kernel that shouldn't be a problem for u

Call att and get a warranty replacement. The damage is irreversible as far as I know. If it truly is hard bricked that is.
