So I did a stupid thing and didn't do my homework. I flashed CM 10.2 for Xperia T (Mint) on my rooted Xperia TL but didn't unlock the bootloader first. The phone won't boot. Just a black screen. If I hold the power button, it vibrates once, but nothing comes up on the screen. No LED light indicating charging while plugged in.
Have I just destroyed the phone?

No. A custom kernel won't work on a locked bootloader, so that is essentially your problem. Just put your phone in flash mode and use flashtool to flash a stock FTF and it should boot up just fine.

Then maybe put your phone in fastboot mode and flash the kernel first... IDK, I did that once and I'm pretty sure that's how I fixed it. With 7zip you can extract the "kernel.sin" file from the FTF, and use Flashtool in Fastboot mode to flash that kernel.
Thanks. I've been trying to put it into fastboot and can't get it to work. From what I have read, I need to hold power+volDown, right? I've held power + volUp to get it to vibrate three times, then connected it with the power & volDown buttons held and nothing - no blue light for fastboot mode. I've currently got it plugged in (using the oem Sony cable) with a rubber band around the power & volDown buttons. Maybe that'll work... I dunno. The led is just staying red, and I can't see it listed as a fastboot devices by typing "fastboot devcies" when cmd is open in the correct folder in the sdk... Any ideas on how to get this done?
Thanks for your help, everyone.

It's a bit hard to understand what you're trying to do
Fastboot mode = just press vol.up, keep on pressing, connect USB, when you get a blue light release the vol. button
Flash mode = just press vol.down, keep on pressing, connect USB when Flashtool is ready to flash the FTF, when you get a green light release the vol. button
As you can see, you don't have to press the PWR button (only pwr + vol.up to reset, but you already know it).
Usually it's enough to flash a new FTF... I don't know why you get that error: maybe a wrong button combination or maybe you didn't install the drivers needed for flashtool.
If your battery is almost discharged, the fastboot method is good to flash only the kernel in order to recharge the battery and then flash an entire FTF.
I guess your device is ok.
Anyway, have you already seen this guide?
I'll give it a shot. I can't seem to get it into flash mode or fastboot mode, though. When I hold down the Volume up or volume down button and try to plug it in, the light stays red and the computer makes a "connect" sound (Windows 7 - rising tones), then multiple "disconnect" sounds (falling tones). The light stays red and the phone is not connected.
I'm downloading a stock firmware and flashtool and will report back when I've tried it some more.

I suggest removing the battery, if you have the chance.
Keep the battery removed and press and hold power and volume up buttons simultaneously. Then plug the phone to your computer and you'll enter fastboot mode.
I revived my XV with the same red led that way.
Had to remove the battery before it would work, tho.
Good luck bro!
Sorry it took so long to get to this. I've just been using my backup in the meantime.
I took the battery out and plugged it in like you suggested. Worked like a charm! I've got it flashed and running now. Thanks!

I accidentally flashed the doom kernel that I forgot to delete off of my phone when trying to flash something else now my phone won't turn on. When I try to power it on it just vibrates and when I try to boot into recovery it just vibrates 3 times. Every now and then I can get the led to light up when it's being charged and I'm holding the power button. But still doesn't power on fully.
Try to flash stock ftf or another kernel via flashtool.

Actually, if all you flashed was a wrong kernel, then you don't need to reflash a whole ftf with flashtool, given your bootloader is unlocked. Only flash the correct kernel in fastboot mode:
Unplug und plug in the USB-cable. Hold Vol+ and the ON-button at the same time for a couple seconds until you feel a single vibration. Let go of the ON-button but keep the Vol+ pressed. You should be in fastboot mode again indicated by the blue LED.
If that works, you can reflash the original kernel.elf or boot.img with fastboot in order to get the phone working again. That way you won't loose any data.
i've just done the same thing

did you fix it?
Hold Vol+ and connect the usb cable that is the right way of Fastboot mode. The Flashtool mode is HOLD Vol- and connect the cable.
Lt30at bootloader isn't unlockable. So I think you should flash stock kernel only.

I didn't think it would even flash to brick because the boot loader wouldn't allow it to even write there, so is it even booting into recovery or flashmode?

Yes. I broke the charger connector thing in the phone. I had it repaired and it was working. I honestly think the place that repaired it messed with the phone to get more money out of me.
They fixed it and when I took it, once it ran out of battery it started to do the same thing again. I cant figure out what it is.

4. Wait till the LED is blue and take your fingers from the phone
The display will indicates nothing in this mode.. It's normal.
Now you can Download TWRP Recovery for C6603.
Have you got an open bootloader.
which rom you wanted to install? stock? custom?
1. Download the boot-twrp-v2.img from (please take the right version for your phone):
http://forum.xda-developers.com/xpe...t/recovery-stable-twrp-2-4-3-0-touch-t21821122. Make your PC available for adb+fastboot:

your solution is not going to help because its a hardware problem and pc companion wont help since the phone wont even boot up
in a similar (or worse) problem :
was just using the phone when it hangs .. Instead being smart and patient, I tried to hard-reset it .. the screen goes dark, my android wear disconnect .. but then I literally got nothing ..
tried to put it to the cradle, connect the USB to computer, no lights, nothing
fastboot mode : volume up + connect USB, no lights, nothing
hold power button : no lights, nothing ..
the phone feels cold, so the procs seems to be sleeping ...
any ideas ?

Hello,
I wanted to flash TWRP into my Z1 C6903 so I downloaded latest TWRP img with official TWRP app and tried flashing it with RASH - Flash tool for Android. The tool stated that the flash was successful so I proceeded to reboot into recovery with the same app. The phone immediately shut down and wouldn't boot back up to neither Android or recovery. It would vibrate once when holding the power button, holding power + volume up would do nothing and phone would not be recognized by PC and even plunging it into wall would do nothing. I tried disconnecting the batter, plunging it to wall and connecting the battery back on which only made LED blink red and device still be not recognized by PC. Can someone help me how to unbrick my phone?
Thank you.

Magic keys for booting to recovery are either:
Hold Vol down and power
release Power when device vibrates, keep holding Vol down
hold Vol down until in recovery
Or:
Power on
if LED blinks press Vol up
If that shouldn't work there's fastboot (only with bootloader unlocked before) or sony flashtool. Just flash latest sony firmware and you should be fine.

I'm trying to install a custom ROM onto my Xperia XZ1 Compact but I got stuck in the beginning. The first step would be to unlock the bootloader. I followed multiple tutorials but none of them worked for me, because I can't get my phone to reboot into fastboot mode. I tried two ways basically:
1. Turn off device, hold Volume down button for 2 secs, plug USB while holding the button. Nope, nothing happens, the only thing I get is the green led is on, I guess indicating that the phone is being charged.
2. Turn off device, plug USB and launch the command adb reboot fastboot (My computer is running Linux but I think it doesn't matter). The phone turns off but does not restart. If I just do adb reboot it reboots in normal mode. I also tried adb reboot bootloader but it just turns off the phone.
Any ideas what I'm doing wrong? Thanks

It seems that this issue is now solved. Black screen with green led on means that your phone is in fastboot mode. Do not expect any feedback on the screen.
