So I was on official stock 4.3 ROM with root and unlocked bootloader. I said to myself I have to try the XzKernel-18.5 so I booted in recovery and flashed the zip. Then I rebooted. The phone remained black. I tried to power it on from the button, but it's only vibrating. If I long press the power button, it vibrates once every second or so.
I plugged the USB cable from computer into the phone and the LEC started blinking red. I kept volume up pushed then plugged in the USB and the blue LED appeared so I guess I can go in fastboot. But what should I do? If possible, without loosing data!
Thank you!

Try to get in fastboot and install a boot.img (for example Doomkernel v20) (fastboot Flash boot boot.img). Then you can access CWM or TWRP to flash your backup back.
Fastboot: Turn off phone, Plug in USB an press http://unlockbootloader.sonymobile.com/fastboot-buttons
Thank you. I solved the problem. I did not knew that restoring TA partiion will relock the bootloader So I had to unlock the bootloader again.

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?

in that case..going to recovery may help u
just check how long ur phone stays in fastboot mode
if it has short span..just go to flashtool
click "fastboot" option (even if ur phone is not in fastboot)
select kernel to flash
locate the stock kernel
don't press open!!!
now connect ur phone in fastboot
and hit open
it should write kernel to ur phone
i had succeeded doing this when i was on wrong kernel!!
Hi!
I have a weird problem with my Xperia SP 5303.
I managed to install fxp custom rom (FXP347-cm-11-20141122-UNOFFICIAL-huashan.zip) and it was working until I used Backup-TA to restore my DRM keys (I did the backup before unlocking bootloader).
After restore (it said it was successfull) then my phone restarted and never completed the boot again.
When I hold the power button, a green light flashes briefly, the phone vibrates and nothing else happens.
Reading other posts about this problem, I tried:
- Holding power and volume up (blue light flashes briefly and nothing else);
- Holding power and volume down (green light flashes briefly and nothing else);
Apparently, if I plug the usb cable I can get to flash mode or fastboot mode. But I don't know what to do.
I already tried to to shutdown through the "Off" button near the battery. Nothing happens.
Any Ideas?
Thanks in advance.

Forget it. I managed to fix it using Flashtool and stock rom in flash mode.

The core reason of why your phone was bricked is that you restores the TA backup on a custom ROM! You should only restore such backup on a stock ROM

Hi!
Yeah, I didn't realize it at that moment. It's my first customization on a Sony device and I thought I should restore the TA backup no matter what.
Fortunately I had Flashmode and Fastboot mode working so I could undo my mistake.
Thanks anyway. I have my FXP 4.4.4 running butter smooth. Much better than stock slow bloated ROM.
hey everyone,
I recently got a warranty replacement of my xperia z3 compact. It came with the latest 5.1.1. I downgraded to .77 (kitkat) through flashtool, rooted, installed the latest dual recovery. In TWRP, I restored one of my old TWRP backups, which was a .28 (lollipop 5.0 I believe). When I press reboot after restoring, the phone won't turn on anymore. No LED or anything. When I plug it into the charger, the LED blinks red. When I hold down the power button while charging, the LED light became solid red.
Flashtool doesn't recognize the phone. What else can I do? Did I corrupt the bootloader? Any advice is appreciated. Thank you.
happened to me, just flash any stock firmware with flashtool (it doesnt need to be recognised) and do not plug in until it tells you to.
then follow the instructions and wipe everything
hope it helps

I tried flashing with flashtool, but when I plug the phone in when asked to, flashtool does not recognize the phone being plugged in.
Do you know why this happened? Did I do anything (downgrade firmware, flash wrong firmware) that caused this to happen?
I cant tell what did it, because flashing any rom will brick mine to this state, and what do you mean by not recognised? Does it say preparing files for flashing? does it give the 'press volume down and power button' pop up?

yes, after it's done preparing files for flashing, a popup appears which tells me to plug in the phone while holding the volume down button. When I plug in the phone, nothing happens. The flashing process doesn't start

Do you be sure to hold the power and volume down button before and during the time you plug it in, until the pop up disappears?
Had something similar, but flashtool magically fixed it

I know it's a late reply, but my Z3c is rooted and running marshmellow. My phone would do the same thing, I thought it was bricked. After monkeying and monkeying it finally came back. The problem was I let the battery drain all the way to 0, and even while plugged in for a bit it didn't do anything. I think it liked it when I would plug it into my laptop instead of the power outlet. From then on, I haven't had the problem because I try to avoid the battery going completely dead.
Although the last time I did by accident, it did come back after plugging it in. My suggestion? Try plugging and charging it in your laptop and then turn on.

sorry about my english
is your PC detect your phone in fastmode ?
press and hold volume down and connect to your flashtool in your pc
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.

I see, thanks. Anyway something is going really bad here, I wish I had never started this. I have managed to unlock the bootloader but the phone does not work now. It hangs at the XPERIA logo and does not respond to power button. It only responds to power + vol up + vol down which restarts the system and hangs again at logo
