1. You've not told us how the phone got stuck in a bootloop in the first place.
Also, do you have the stock rom?
2. Launch device manager then connect the phone to the PC while off. Does Device Manager refresh?

I tried to swap memories by editing the vold.fstab file,after that i got bootloop,and device manager didnt refreshed when i connected the phone,so i havent searched any roms,because no use of them if phone could not be detected

hold vol down button before connecting to the PC then check device manager

Already tried that,still nothing

try a different usb cord or PC
what button combo did you use to attempt booting into recovery mode?
and did you make any backup before modifying the vold file?

1st problem : USB data connection not working
2nd problem : Hang on Logo

solution 1: Check USB connector, PC port, at last replace USB connector.
solution 2: If connection is OK, then backup or read phone's firmware. Extract and find build.prop form system.img from backup firmware and see ro.build.version and search at GOOGLE or tell us here.
solution 3: For searching for firmware, you can search by BoardID on circuit.

NOTE : If connection is OK but you cannot read/backup firmware, check hardware error, may be eMMC damaged.
