In that case you might want to follow the instructions on the first link... beware though, when I unlocked the bootloader, it also created a bootloop, forcing me to reinstall my rom.

I tried unlocking bootloader and it went into bootloop after that, I flashed stock rom and now the bootloader is not unlocked still.
will it go again in bootloop after unlocking bootloader?
HELP!
I followed every instruction, enabled usb debugging, backed up TA, then used flashtool to unlock the bootloader (after entering the unlock code flashtool showed OKAY, then the device rebooted). now I'm stuck in the bootloop. when I try to connect the device with flashtool to flash the stock ftf, it says usb debugging is turned off! how can I flash the device now? Is there any way I can turn on usb debugging again?

Just turn off your phone...When flashtool's ready to flash, connect your phone with down button pressed..
Flashtool's never said usb debugging on/off when the device is off..

Relock doubt
I have unlocked my bootloader and want to relock it but have not yet made any TA backup....so can i make a TA backup of another xperia-L device and flash that in my Xperia-L?
I, recently tried to unlock my bootloader via flash tool, but for some reason, my rooting status (my bootloader) is unknown (before was unlockable. I relocked and unlocked it again but still no luck. Then I flashed the firmware with flashtool.. but my bootloader's status is still unknown. I think the error is due to some file named x10flasher in the flash tool. What i must to do for have back bootloader unlockable?
Please someone Help me

Z3 Bootloop

My cousin has an xperia z3 dual d6633 we wanted to root it so what we did was :
1- we unlocked the bootloader using sony's official guide that was a success
2-we flashed twrp using
Code:
fastboot flash recovery TWRP.img
That appeared to be a success but we failed to boot to recovery i tried everything to boot to recovery from pressing power buttons with each volume buttons or both to even using
Code:
adb reboot recovery
and even that didnt work it always booted to android
3- when that didnt work one guide on the internet said to boot directly from the twrp image i had on the pc using
Code:
fastboot boot twrp.img
and thats where things went south it still booted into android but this time it was stuck in a bootloop it would boot into the screen thats right after the sony logo (the one that looks like the ps4 booting screen) and it would keep doing the animation non-stopping
4-we tried using xperia companion to fix it but it always said bootloader was unlocked
5-we tried relocking the bootloader using both
Code:
fastboot oem lock
and
Code:
fastboot -i 0x0fce oem lock 0x<unlock key>
mimicking the unlock bootloader command from sony's website but the lock bootloader keeps going on forever nothing happening until we take out the usb cable then it says failed
now i have two questions
1-can this be a hardware problem? Basically can the steps i made damage hardware?
2- is there a way to either relock the bootloader to fix it using companion app or fix it using any other program at all?
Thank you for answering
