Does flashtool recognize your device?
Like, does it say -
" Device connected in flashmode " ?

Try to re install the driver

DO IT ON UR OWN RISK
If u have twrp recovery then go to wipe/advanced wipe / select cache ,data, SYSTEM ALSO
after that open flashtool before connecting device , open 4.4.2 ftf file
And it will start preparing file and it will prompt u to connect ur device and then connect ur device it will successfully start flashing

If only I can access recovery but I cannot access recovery every time I press power on the device it will go to bootloop.
Yes i already tried flashing 4.4.2 ftf but when i connect my phone while pressing volume down it will always bootloop

The 4.4.2 ftf is in firmwares
So replace it with new 4.4.2 ftf file

yes thats what i have been doing ever since i also tried 4.4.3 or the older 4.3
I want to emphasize that i know to flash firmware I know where to put it obviously.
I think there is no problem with the firmware.
I think the problem is every time i insert the phone via usb it will bootloop so i cant flash anything.
If you have advice just to stop the bootloop during flashing that would be great

fiyanshu · Feb 26, 2015 at 2:28 AM

Then its hardware problem may be

I think it is just soft brick
I can activate fastboot while connecting to pc by pressing power+volume up led will turn to blue.
But I cannot use fastboot since my bootloader is locked :crying:
