If it says bootloader unlock allowed: no, then fastboot is missing from your phone which is necessary to unlock the bootloader. So yes, you cannot do that if that's the case.

Yes it says bootloader unlock allowed: no, then there is not way to change the status of bootloader for yes.[emoji22]

Fastboot is always there... Even on carrier locked devices you can even flash a custom kernel if you want but it just won't boot you can also install a ROM for locked bootloader

Seriously?? Then might be we can find a solution somehow using custom kernels? But I have tried for hours I could never get into FASTBOOT mode. It went into FLASHTOOL(green light) mode but never into FASTBOOT mode. I inferred, FASTBOOT is missing from the device. I think it is missing.

Well..i am not sure what kind of locked device is this. We don't have career locked phones in my country. They sell it without any lock...
can anyone explain it what kind of lock is this ? and it's not even allowing to root...

Bootloader locked means u cannot load anything at boot that would tinker with the basic core of the device, like u cannot use custom kernels when ur bootloader is locked that is y ppl unlock their boot loaders Google for further info.
As for the OP's problem :
This is a known issue when u root ur device without unlocking bootloader, the solution to this is to do a full repair using Sony Suite which will result in loss of all data phone ,SD card etc .
check this link out its clearly stated over there
http://forum.xda-developers.com/showthread.php?t=2186368
Troubleshooting:
if your device has unlockable bootloader then after applying this hack the bootloader status will turn "Bootloader unlock allowed: No"
in that case dont worry the users have reported that doing a repair via SEUS will flash back stock firmware and turn this status to "Bootloader unlock allowed: Yes" (the same might also be achieved by flashing a stock FTF using FlashTool <yet to be confirmed>)
ROOT WILL BE LOST BY DOING THE ABOVE AND YOUR INTERNAL STORAGE MAY GET WIPED!
SO DO A BACKUP OF APPS & INTERNAL STORAGE ON AN EXTERNAL SDCARD/PC
How so some people can unlock the bootloader and some can't??

[Q] cant unlock booterloader

hi,all,im trying to unlock BL by flashtool beta6,but its say No loader found for this device
OS;4.2.2 ,423,HK
It says underneath it "cannot be officially unlocked"
So my guess is your bootloader is permanently locked. Type *#*#service#*#* and go to service info then configuration. It should say "bootloader unlock allowed:" yes if you are able to unlock it.

Use Google. A simple query like "how to unlock xperia z bootloader" would probably do it. But since that is such a far-fetched idea I understand how it could have slipped your mind...

Either try the latest flashtool and do it again or search for doomlord's post on how to unlock bootloader.
But before trying, I would highly recommend backing up your TA.img

Why are you using Flashtools Beta 6? That version has been superseded by the latest release on the flashtool site....
Go read Doomlord's post on unlocking the boot loader (which is the official Sony method)- you can do it quick and easy with fastboot......
As has already been said....read the post in Original Development about backing up your TA (DRM & BE) partition BEFORE you unlock your bootloader.

[Q] How to allow unlock the bootloader

Hi,
A simple question: if I have the Bootloader locked, and my smartphone (going to the service test page via *#*#7378423#*#*) says me that rooting status about bootloader unlock allowed is NO, it's due to my smartphone is locked by my carrier? (I have followed this instructions: unlockbootloader "." sonymobile "." com)
Flashing the ROM is enough to have it unlocked?
Thanks,
Marc

If it's carrier locked then there's no unlocking it.

If you got it direct from a carrier, NO.

What does LB/UB mean?

Hi, I keep seeing people mentioning LB or UB in reference to phone models and roms, what does either of those mean? Thanks

Type on Keyboard *#*#7378423#*#* and there will be Bootloader Unlock Allowed: YES or NO. If is Yes then you can Unlock it, if is NO you cannot Unlock it, never.

A new phone is always locked. You have to unlock it by yourself.

Ok
The question is
What happened if i choose the rong option
I mean i have unlock bootloader device and i choose lb when i inistall the rom
Nothing when you have a unlocked bootloader you are free in terms of flashing.
But when your on a locked bootloader and flash a Rom that requires a UB you will may get a bootloop, because the most UB have inside a custom kernel which will not get flashed or in the worst case you will just have a bootloop

Can I relock my bootloader?

Hey, so my Moto G got an unlocked bootloader, but I'm selling it to get the Moto G 2015 (or any phone good as it). Is there a way to relock the bootloader, so I can handle it to the new owner good as stock?
In terminal type 'fastboot oem lock'. It's relocked then, not locked, that means the warranty is still gone but the functionality is the same as from a locked bootloader.

Will try it later, thanks! If the new owner wants to unlock it, he just should do the normal unlocking procedure?
