[Q] Xperia zl (c6502) bad bootloader

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?

I agree with what is being said here. However I would recommend that you flash back to .434 first that these methods have worked for many times, and it is more known version for attempting this.

Just reflash the .253 with a full wipe using flashtool.. it's bit trickyto enter to flashmode during bootloop. Just make sure to press volume down key & plugin the USB cable when the screen goes off.. type *#*#7378423#*#* in dial pad once it loaded you will have bootloader unlocked:Yes

I had the exact same problem.
I had unlocked my bootloader via the official Sony way.
Installed CM10.1.
Went back to stock Sony ROM (after relocking bootloader and flashing a tft via flashtool).
Tried the official way to unlock my bootloader, and all the time had a boot loop.
Tried to unlock my bootloader via flashtool and didnt have a problem.
Back to CM10.1 for me now!

If your phone reboots mid xperia that mean there is a system error.
With doom v6 kernel that is 4.1.1 based so that might be why you are getting bootloop if you are trying to flash kernel on a up to date 4.1.2 system

[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
On android 4.0.4
Sorry if i posted in a wrong forum.I'm new here

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

xperia z c6603 IMEI corrupt and restarts after flashing a c6602 firmware

I have a sony xperia z c6603 , it was never unlocked from the start but it worked very fine on its original firmware, android 4.1.2. But then someone flashed a c6602 android 4.1 on it and now the IMEI is corrupted and it restarts every 9.3minutes.
It says bootloader unlock allowed: Yes which I guess means the bootloader is locked and can be unlocked, but since IMEI is corrupt, i cant request for unlock code from sony or use fastboot.
My only other option is the famous flashtool. I have three issues with flashtool.
1. I already downloaded the correct firmware and preparing to flash, so I click on the flash icon and start flash (Using Androxyde flash tool). It goes through the normal process and then an empty device selector screen comes up, with no option but to cancel. and when i cancel, it says "loader not found for this device"
2. Okay, after step 1, i am thinking "maybe i have to unlock the bootloader first" so i click on the BLU button and connect the device in flash mode, it starts and the empty device selector screen comes up again, once i cancel, it says "your device can not be officially unlocked"
3. So i did a little bit of digging around on here more and found that i have to update xflasher.jar to beta6, and so i did and flash tool started as "androxyde and bin4ry flash tool" .Only problem is when i click on the flash icon and choose flash mode, nothing comes up, i cant get into flash mode. but I can get into every other thing like fastboot mode and BLU
Please if you think you have an idea on how to solve this problem, please reply. I cant afford a new phone and I would also like to know if my phone can be repaired too, I also dont have a lot of time to waste trying to repair it.

try to reinstall flashtool after deleting it first .. install fastboot and flashmode drivers and drivers for ur device from drivers folder in flashtool folder.. disable any antivirus and any app that could interfere and unplug any usb device ... try to flash with flashmode
