Info 2 Karbonn A7+ new ICS flashing problem.


I tried upgrading the baseband of my Karbonn A7+ using the procedure of Mr. Guneet. When i did the upgrade the phone rebooted and the screen was with all garbage pixels.
Phone SD card was not accessible through my computer. When i tried flashing the phone in the recovery mode, the screen use to get stuck in the garbage pixels mode.
I tried flashing the phone in clockwork recovery mode but to my dismay nothing is working. I need help with how I install the ICS ROM in my phone. As I am not an Android expert, please give me detailed procedure. Your help would be appreciable. Thank you.
