[Bricked][i9300/S3][Advise] No Boot/No Mount/SDS

I9300 died about a week ago, Confirmed dead today. All i did was flash the unofficial cm12 build from XDA (Used it as a daily driver for a week). Then felt I could wait longer for the final build. So flashed cm11 24th December Nightly, and the problem started, it would reboot often, Thought Ill just flash the official rom and boom no go. Odin kept failing, after which, kept reading xda and various other sources and trying, in the process, was able to flash the official 4.3 Build, only for the phone to freeze on the samsung logo.Then it happened, it would boot into recovery all mounts points started failing on subsequent boots. Then I don't know how but cm11 booted up. Well I was happy and finally fell asleep, a bit happier, When i get up its dead. No Boot, No download mode, nothing. SInce it wasn't in warranty took it to an unofficial mobile repair store, left it with the guy for a day, he said it was the emmc and it would take him a week or more to procure a replacement. hence I took it to another store who claimed he had fixed i9300 with the same problem. Left it with him for nearly a week. Today he tells me its dead, a motherboard replacement might (no guarantee) fix it. Hence I've decided to let it go..

CM12 Nightly for i9300, you were too late. :(

Advice to i9300 owners: Do no flash the unofficial cm12 builds if you do, do not try going back to kitkat. Stay on the unofficial till the official is released. If everything fails do not try flashing another bootloader, as you will come across articles which claim will fix the problem. A few mistakes I think I made which in turn triggered the exynos SDS (Sudden Death Syndrome) bug.

Hope this helps someone, if you have a i9300/S3 that's not booting take it straight to an authorized Samsung Service Center. You might have a better chance of reviving your S3.

P.s. PM me if anyone need parts.
