This is in response to your reply on the XDA forum
I am having the similar phone behavior as mentioned in the post after I had flashed the "system" partition of the phone using "recovery.img" by mistake.
I had wiped and re flashed the partitions with the system.img and recovery.img's I got from the internet but the problem persists and the fastboot mode is the only running thing in it.
The stock ROM mentioned in the link is a .pac file and it appears that phone is required to be in a running condition to use that SP flashing tool since I tried that and the phone was not responsive to it.I was also wondering if I can extract the files from the .pac and then use fastboot or just do a fastboot update to install a new ROM in it?
Your help would be highly appreciated.
