Here's what happened.
I was using 4.2 Jelly Beans ROM and wanted to try 4.4.2 based new roms.
I backed up with Titanium, updated TWRP to 220.127.116.11 with Flashify, wiped cash+data+dalvik and flashed Slimkat 4.4.2.
It seemed like it's working well until I found out that it won't recognize my 32GB SD card.
I decided to flash another rom, to 4.3 Alliance rom.
So I started flashing MJ9 firmware via Odin, but it got stuck on the screen on the attached pic.
It did not make any progress for more than 1 hr, so I disconnected phone from PC and tried to boot up.
It's stuck on the screen on the attached pic.
Please help me out..
