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?

[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!

Hard brick z3 compact - flashtool does not work

hello all friends.
I have a hard brick in my Z3c ... rather than install a full rom, I installed an update to 135 MB, and had given full wipe the system the device simply does not care anymore.
FlashTool does not work, already tried everything and it will not.
Error of drivers but they are installed all the drivers ... ok.
I TWRP on the device but can not access it for flashing back up what I had done.
Simply do not have access into the Z3c ...
Some logical solution to this problem ??
Grateful to all the friends who can help.

Unlocked bootloader?
Is the front panel led still working?
Can't you see the Sony logo?
If you press power + volume. up for some seconds, does the phone vibrate?

Fastboot mode?

Nope, it's just a soft-brick
Press power + vol.up until it vibrates 3 times.
Then flash a stock firmware with Flashtool. Look here: http://forum.xda-developers.com/z3-compact/general/list-stock-firmwares-d5803-d5833-t2906706

I had that exact problem when installing Cyanogenmod a couple of days ago, realized there was no internal storage anymore so i flashed a pre root zip and got my files back.
I was using XZDR, I think it is just a problem with the latest twrp...

Xperia Z1 won't enter recovery mode

Hello, my Z1 doesn't enter in recovery mode. I've tried with TWRP and CWM and it doesn't work. I tried in classic way (turn off the phone, hold the power button+vol. down and I've tried with both vol buttons) and with ADB is just restarting normally.
Notification light must be on when I turn on the phone but mine doesn't do that:crying:

Did u have try to re flash cwm or twrp?

I have the same problem. Yes I've tried to reflash TWRP and CWM and nothing happend

try installing ndr utils and see if it helps

I've tried and nothing happend. I still can't get in recovery mode. Maybe the motherboard is broken?

I have the same problem sometimes, when i flash new ROM.
Try flashing Philz dual?

LB or UB?
if unlocked bootloader flash latest ta that enables real recovery then
fastboot flash recovery recovery.img
This way you won't lose recovery even if you mess up the boot(kernel) partition

Reinstall NUT Recovery
Hi,
First of all install NUT Recovery for you Xperia Z1 and after installation of recovery turn off your phone.
Turn on your phone and repeatedly press the Vol Down Key until you see the purple color in LED Notification.
Then you can see the TWRP Recovery.

Z1 bricked after trying to reboot into recovery

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.
There are enough threads concerning this

That doesn't work, the phone doesn't respond to any inputs from buttons.

Then Flashtool is your friend. You have to reflash the Sony Software.
