Thanks arffrhn...I was able to get back to 4.3 stock and was able to gradually upgrade from there to 4.4.1
Here are the steps I followed.
when I was stuck at Google logo...I was still able to get into fastboot and TWRP etc..
I downloaded 4.3 and 4.4 builds from Google Developer site ( Link
I unzipped them including zips with the main tar file...
followed instructions in the guide linked by arffrhn below (section D from the guide)
when I got to flashing boot loader it FAILED.....
error: not the same image...etc...
note when you go into fastboot using vol+power button check out your Product name, bootloader version and baseband version.....
mine was MAKOZ20i version # 2.0.1700.84, so I had to use the mirror site linked on the guide (section D again) to download an older stock build (which referenced my build number)....extracted files from this build
followed the steps again as mentioned on the guide.....
I was able to get back to stock 4.3
from there Google updates you to next version of 4.3 ..after reboot it will start upgrading you to 4.4.1
you may have some hassle with SuperSU....you are better off with downloading the zip file from the guide and installing it through TWRP.
note: I was not able t get TWRP working after upgrading to 4.4.1.....it gives me "No command" error ...I tried to fastboot TWRP multipl times but that didnt help.....
