OK guys so I got my xperia zl today, updated to 4.3 (.569), unlocked the boot loader, then tried flashing a CWM, now the phone is utterly and totally bricked, I tried the volume buttons + power button trick nothing, won't turn on at all, no fastboot, no flashmode, pc companion wont recognize it, the only thing I can get out of it is a single vibrate if I hold down the reset button at the back but even after that I get nothing, at all, the only thing that does anything is holding the reset button, any help would be greatly appreciated and if one of you magnificent people can get my phone working again I will send you money through paypal as a thank you,
This phone doesnt have any Volume +/- power button trick. It ONLY has the yellow reset button. Its a pain in the A*S!
Try a few things first.
1) When you hold down the yellow reset button, are you ONLY holding it down for a few seconds, and it vibrates ONCE?
Have you tried holding it down for 10 seconds, until it vibrates TWICE, indicating it has powered off completely, and THEN try connecting it?
2) If step 1 got your phone to power off completely try:
-Connecting your phone to your PC via USB with the volume DOWN button held and see if you get a GREEN L.E.D. If you do you have
successfully entered flash mode, in which case you can simply flash an FTF file with flashtool.
-Connecting your phone to your PC via USB with the volume UP button held and see if you get a BLUE L.E.D. If you do you have
successfully entered fastboot. From here, as long as you have ADB and your devices drivers installed on your computer, you can flash
a boot.img or "Kernel" with a fastboot command in a command window (fastboot flash boot boot.img). The easiest way to get a kernel or
boot.img with a baked in recovery is to download the latest Cyanogenmod, unzip and extract the boot.img, and flash it via fastboot.
Since you have an unlocked bootloader already, your device should be able to use an AOSP kernel.
From there you should be able to at least boot into recovery, and flash something from your SD card.
Id recommend just flashing the latest Cyanogenmod just to get your device up and running. From there you should be able to follow steps
get back to stock if thats what your looking for.
I hope at least one of these options work.
If not, like that last guy said, take it to a service center and get it checked out.
GOOOOD LUUUUCK!!
