Accidently Flashed Doom kernel I Bricked my Sony Xperia TL LT30at

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.

you try to flash a different kernel is not considered

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?

Can't go into fastboot mode. Please help!

Hello. I have a razr I and decided to unlock the bootloader. I tried the button combination power + volume down several times, but the phone just powers up normally (actually rhe screen flashes for a second, but doesn't go into fastboot mode. I trided using adb reboot fastboot but the device just reboots. What can I do about it?
NVM, just did it by fastboot reboot bootloader...

Ok, one more thing. It seems my device ignores the key combo, but I was still able to get into fastboot mode by using adb. However, I have tried to flash a custom recovery with no success.
I tred using the supplied installer and after rebooting I get to the open robot screen with the red exclamation mark. Then, after holding some keys (not sure if power or power + volume down I get into recovery, but it's still the stock android recovery. Then I tried flashing the recovery image from fastboot mode. It sait the recovery was flashed, but still cannot boot into recovery. What's wrong with my phone?

Just incase you need to do it in the future:
Hold volume down, then hold the power button. When it begins to vibrate release the power button and keep the volume down button pressed until you get into fastboot.

Alright. So how about the never appearing CWM recovery?

[Q] Did I just brick my Xperia TL?

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.

Flashtool says my phone is locked and can't be updated.

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!

Anyone knows how to repair hard bricked phone?

I was flashing my phone and half way through my computer lost power. Now the phone does not start. I can't get it into fastboot, or flash mode.
Pressing 'vol up' + 'power' doesn't work either. Anyone knows how to repair a hard brick?

Does vol down + power work?
Does the charging animation show up?
Does the led emits a light?
At least you could say the support that your device turned of while applying a firmware update and that they need to give you a new device :silly:

No charging animation.
if I press vol up + power longer enough the red light will turn on, but it still can't be detected by the computer.....
btw, yesterday I updated my phone to firmware 52.0.A.8.25_R5B and install the new twrp but it was stuck in a boot loop, so I repeat this process four times and still no luck, until the fifth time my PC died on me bricking my phone........

Did you "fastboot boot twrp" or "fastboot flash boot twrp"?
Weird, I hope the IT guys can help you.

same problem? you have solution?

Does holding volume down + power while plugging the phone into a computer show a green light?

i need help Sir

Bootloop, help!

After flashing AEX ROM phone hangs on boot screen. I can't force it to shut down, I have to wait until battery drains. Then I connect the charger, phone immediately boots up, here we go again...
I can't use newflasher.
Brick?

Use Sony Emma.

My phone is also bootlooped after i failed to flash the software.
I don't remember but maybe hold volume up and power button and the phone vibrates 3 or 4 times and after turning off.

Brick is not likely. Plug the phone into a PC, hold power button and up volume until it vibrates then hold the volume up until the blue led shows, meaning you entered fastboot mode. Then open a terminal for adb, wipe with fastboot commands and flash another rom of your choice.

I can flash zip using fastboot??
Code:
fastboot flash system rom.zip

Somehow key combo worked and I got into twrp and flashed rom
