I'd try flashing my Xperia SP C5302 but when it was supposed to be done, I'd try turning on the phone, but it doesn't work. First it started booting with the Xperia and Sony logo, then the animation and kept looping. When I left it alone for hours, now I can't turn it on. it'll only keep flashing red light. when I plug to a charger, it goes to Green, then Red with SONY logo, then back to green. don't know what else to do.

P.S. I have the Flashtool 9.15 version and several C5302 ftf to choose from.

You should try flahing kernel only with flashtool.
You'll be able to charge your phone, and then, flashing whole FW

sent with a locked xsp running P.A.C.

Based on my experience. That day i also got a bootloop. I follow all the step...in the end get bootloop

I did try to flash kernel again after bootloop, but can't.

In the end, i use SUS to update 266 stock rom.

This happened to me a few times when I first started out.

I kept notes in case it recurs in the future:


1. remove usb connector
2. open back cover and hold the 'OFF' pinhole for 10s until you get 3 vibration - this turns off the phone
3. press volume down, then insert usb charger (which is plugged to your pc) - this puts you into flash mode
3. open flashtool in pc and choose flashmode, and 266 kernel (or other kernel of your choice) to reflash. And follow the instruction to re-flash the working kernel


On item 1, google for where the 'OFF' hole is.
On item 3, you might want to fire up SUS or PC Companion rather than flashtool (I did not try this so don't know if it will work)
