[Q] Xperia zl (c6502) bad bootloader - Xperia Z Q&A, Help & Troubleshooting

Hello community,
I write because I had a problem when installing CWM Recovery for my xperia zl (C6502), after doing the procedure, my devide did not boot again, I suspect that damage the bootloader that when connected to the PC does not recognize it, I can not even enter fastboot mode, just a light red flashes and does nothing more.
That option I have to get my device again?
Thank you for your contributions

Did you root your device first?

[Q] Xperia Z showing only Sony Icon and Red LED in a loop

Hello,
I have a Sony Xperia Z and I tried to flash cyanogenmod 11 on it. I checked before if the bootloader is unlocked but the option in service menu said "No" which means that the bootloader can not be unlocked.
I still moved forward with flashing the CM11 on it and at the last step of flashing CM11 it gave me an error and failed to flash CM11 on it. In the recovery mode, I clicked on "reboot now" option and since then the phone is not booting and is going in to a loop of showing Sony icon and a red led light.
I tried brining the phone in fastboot mode by holding power button and volume down and attaching the USB and it does show me a green led for a moment but the screen is complete black and nothing shows up.
adb devices command does not show anything (I am using Mac OSX 10.9.5)
I installed flashtool. It does detect the device but says that the "Device is locked" and does not show any option to flash the stock ROM.
Sony's PC Companion does not even detect the device.
Please help me in finding a way to being it back to its original form.
Regards,
Ashish
You absolutely need an unlocked bootloader to flash Cyanogenmod to your device. You have soft bricked your phone by flashing a custom kernel to it when the bootloader is locked.
You should be able to fix this by flashing a stock rom with Flashtool (the unofficial Flashtool, not Sony's Emma). Either download an FTF from the general section or package and flash one by following this guide - How to package and flash stock roms in FTF format. Obviously, do not install the Windows driver as in part 1 of the guide if you're using a Mac.

[Q] Sony xperia bootlooped

I unfortinately formated system in clockworkmod touch recovery. Afterwards phone gets stuck at sony logo when i power on the phone. Am able to boot into fastboot and flashmode using key combinations but cant enter into the clockworkmod with key combinations as i used to do before the system format. However, i unlocked my bootloader and rooted the device before i had this problem. As a result, am not able to get sony pc companion to repair my phone. I tried flashtool but then upon flashing, it asks me to enable usb debug mode and am not able to enable debud mode since the phone doesnt boot past the sony logo.
I will appreaciate it greatly if anyobe can help me get my cute phone out of this situation

You can try with Emma, it works only with unlocked bl. You can find it somewhere on Sony web page (google it).

If you can get in fastboot mode you can allways relock your BL and repair it via PC Companion.

[Q] Unable to boot into Fastboot, Recovery or Flash mode

Hello guys,
Today I am encountering a very weird issue. I was on CM12 nightly on my xperia z1 and I decided to check the official Sony firmware since I was curious. I downloaded the official update from Sony PC companion and flashed the files with flashboot. After the "android is upgrading" window with all the apps being updated the device suddenly reboots. I thought okay it might be normal but it is now stuck on that procedure. It attempts to boot goes through the logos and in the animation but restarts again.
I tried booting into recovery to wipe data cache etc. but turns out the device is unable to boot into recovery and instead it attempts to boot normally.
Afterwards I attempted going into fastboot and flashmode and the device just shows the charging screen. Not even the notification light reacts accordingly to the mode I am trying to boot into.
I also tried adb but it didn't find the device.
All help is highly appreciated.
Many thanks in advance to anyone who has any idea on how to resolve this issue.
Use flashtool to reflash your system.

What's wrong with people these days? Did you even read what the OP posted? If you did (even if you just read the title) you were able to see that he is NOT able to boot into flash mode rendering flashtool useless in this case!

flash mode and fastboot mode cant recognize the phone but still can boot in to sony logo?
it werd did you try it with another PC or USB cabble? and full charged z1 before try all method again, maybe problem is your phone out of battery.
try some some official repair as sony companion or Sony update service.
we cant do anything if both of flash mode and fastboot mode not work.

xperia Z3c bootloop after flashing CWM

I recently got a z3c and decided to try to get a slim rom on it.
I have done the following:
I unlocked the bootloader.
This was done successfully to the best of my knowledge
The next thing I did was flash a cwm image to by z3c using fastboot. The problem was that I flashed the z3 version on my z3c.
The device would boot but the screen would be blank.
Later I flashed the z3c boot loader named : Z3c_DooMLoRD_AdvStkKernel_v01_FW-105
After this the device goes in a boot loop. I am able to access CWM.
I have tried to root the phone as well as flash the slim rom in an attempt to fix it....
Wiping disk / cache doesn't help.
Also for some reason even though adb drivers are installed I cannot use it so I can't get the twrp install to work.
I have no idea what to do can someone please help?
Thanks,
stp
I have same issue....Phone is ib bootloop...i can still go to fastboot mode....
Anything can be done here????
Flash an factory image with flashtool then you will have original recovery. Then reinstall CWM, maybe smth went wrong.
Tried flashtool---Ended up with errors as attached pic
As i cant bootup my phone...USB Debugging option cant be ticked
I was running SlimLP (unofficial) while bricked my phone....
Anything on that please....
I managed to recover my phone. I don't think you need usb debugging for flash tool. What I did was turn the phone off (power and volume up seem to be the buttons that force shutdown and break the reboot loop).
flashtool will prompt you to connect when you flash the ftf file and you hold power up and volume down when you connect the usb cable. If you have issues flashing (it hanged on me on system.bin) try restarting your computer.
Resolution and Problem Exp
Right after flashing the device recovery through fastboot the USB cable is plugged and that seems to loop the boot loader, so you need to force shutdown while looping by pressing POWER + VOLUME UP, and after that unplug the USB cable. You will notice that on boot now the light is no longer red.
