I used the first method (as that was the only option available for me) and it indeed solve the problem of bootloop.
here is what happened exactly:
I used Windows 7 32 bit pc as guide asks to avoid w8 -8.1.
followed steps exactly as said in guide but after connecting the phone (xperai E dual c 1605) there was error and flashing process was aborted but meanwhile some driver got installed. Its strange because I remember that I had installed all necessary driver (had connected my phone quite few times on this pc and had connected phone by vol down and connect to pc to get green light way as well ) and had also installed driver through flashtool as said in steps in tutorial..
anyway I rebooted my pc because I thought that would complete driver installation process and tried again but it did not worked and again some driver got installed but then this time instead of rebooting I tried again immediately and it worked this time.
So if u get error and instead some driver get installed just try again and most probably it will work
tip : use right click Run as admin on any exe file
PS : quote: . In the huge list, scroll down to the bottom and tick the ‘’flashmode’’ and ‘’fastboot’’ drivers. in latest flashtool version those options are right at top

if you got bootloop you did it correctly .....flash stock ftf after that, you are ready
I have flashed it and everything is fine but now I am not sure whether my bootloader is locked or unlocked .. I searched but there is no definate way to tell .. in xperia Z forum some asked to flash a kernel and if you get error it means its bootloader is locked (though I am not sure if it will harm phone and again cause bootloop or not
( off cou2rse I wont flash xperia Z kernel on xperia E dual ))
