yes, i have them installed. i flashed another ftf too from italy so yeah drivers have installed

i saw in threads that bootloader unlock allowed : no means we cant unlock bootloader but is it normal that on sony website they give the unlock key? like i put my imei there and they give me the unlock key but in fastboot oem unlock command it says
FAILED (remote: Command not allowed)

I ran into a rare situation on an old Xperia tablet that said the same thing but had twrp installed. But with your situation u could be looking at a paper weight if u try to flash anything. It's hard to say though. Usually bootloader unlock: no means don't flash or u get brick. Does it say bootloader unlock or unlocked? You also have to realize that just because u get a key doesn't mean u can unlock. An imei doesn't mean much except verify it's a Sony phone

[Q][LB][D2306][.182] Unlockable bootloader : No

Dear all senior members,
Can I seek a kind attention?
My M2 (D2306) has no permission to unlock the boot loader. I've the unlock code via email. But, it says "command not allowed" when I tried fastboot via cmd. Even flashtool failed to unlock it.
What can I do to unlock it??? I'm using .182 build version.

Hi, if you have "Bootloader unlock allowed: no" in the Service Menu then you can't unlock it.
There is nothing you can do to change it from NO to yes where it says bootloader unlock allowed NO, the only way to change this is to change the device for one that says bootloader unlock allowed yes

Unlock bootloader

I have been searching the forum and I cant seem to find a definitive answer to my question
I've an xperia z5 and it says root status : unlock bootloader no
I got the unlock code from sony but, I'm thinking the carrier has also put an extra lock on the phone
Ive tried using fastboot and unlocking it with the code but I get
FAILED (remote: Command not allowed)
Is there any way to unlock the boot loader on this device
and if not is it possible to flash it with a rom without using the bootloader/sdcard method and installing the rom from a pc/usb
Im guessing no
fastboot flash recovery sony-recovery-z5.img
sending 'recovery' (31976 KB)...
OKAY [ 1.432s]
writing 'recovery'...
FAILED (remote: Command not allowed)
finished. total time: 1.450s
any help would be greatful, Thanks

You can check it by typing *#*#7378423#*#* in dialer (*#*#SERVICE#*#*) hit Service info > configuration > rooting status: bootloader unlock allowed: "yes"= unlock allowed,
"no"= not possible,
"unlocked"= already unlocked.
Yea thanks langeveld024, I already checked and I was looking for a solution to unlocking a perma-locked bootloader
rooting status: bootloader unlock allowed: "no"
f**ing mobile carriers , I doubt they will let you unlock it if you asked, They would just refer you to sony and then sony would tell you to go to vodaphone
To be fair its not sonys doing , its the carriers that put the extra lock on it, sony leave it so its able to be locked or unlocked
Ill just have to wait until someone comes up with a hack/exploit

oem unlock is not allowed

Hi, I've got the 6045Y model which I've been trying to install twrp on, but I can't unlock the bootloader; it says oem unlock is not allowed.
I've tried on os x and linux with sudo but it's the same on both sides. As my phone isn't carrier locked, I don't understand why it's not allowing me to unlock the bootloader. There's also no oem unlock option in the developer options.
Any help?
You must do something wrong?
Can you trY with Windows
You need Alcatel Drivers+Minimal Adb and Fastboot
connect device you must enable debugging and then
-type "adb reboot-bootloader" to reboot into bootloader. The device should reboot to the screen showing "alcatel onetouch...powered by android". This is bootloader mode.
-Then type "fastboot -i 0x1bbb devices" should show some numbers and "fastboot" after the numbers
-Type "fastboot -i 0x1bbb oem device-info" shows device info including bootloader status (e.g. locked).
-Type "fastboot -i 0x1bbb oem unlock" to unlock the bootloader; after this you should get, for device info,
-Type "fastboot -i 0x1bbb oem device-info" and you should see "Device unlocked: true"
-To reboot normally: "fastboot -i 0x1bbb reboot"

I tried on windows just now and the same thing happened: "FAILED (remote: oem unlock is not allowed)". I should mention though, I flashed twrp before unlocking the bootloader. I wonder if this is what's causing the problem.
I dont remember if this option was there, but you can try. Go into Settings/About Phone, scroll down and click on “build number” continuously until you see a toast notification telling you that you've enabled Developer Options. Go back to your Settings menu and enter Developer Options, scroll down and click on the “Enable OEM Unlock” checkbox, also make sure you enable USB Debugging while you're in the Developer Options menu.

Same problem with same UK model and installed that patch too. I managed to flash TWRP and install PAC ROM still bootloader claims to be locked.
fastboot -i 0x1bbb oem unlock
FAILED (remote: oem unlock is not allowed)
fastboot -i 0x1bbb oem device-info
(bootloader) Device tempered:false
(bootloader) Device Unlock:false
easiest way is to download stock firmware with flsh tool for panasonic eluga switch (rebranded idol3),. Flash it with using the included flash tool. then unlock bootloader. Then use mobile upgrade Q 5.0.6 to go back to stock. And you are on stock uk firmware with unlocked bootloader.
I flashed someone's stock 6045Y(Europe) Firmware: 5.0.2-010 03 but couldn't unlock it either. After that I flashed 6045-i806-DCZ. I was really surpriced it let me do that while claiming to be locked and untempered. After that I did factory reset and flashed PAC-ROM. I'm not sure why should I bother to unlock bootloader if I already have TWRP and PAC-ROM flashed. I've no idea how can I even flash rom's with locked bootloader? Maybe oem device-info is bugged.
Anyways I download panasonic eluga switch firmwire, gonna test it after taking backups.

the Panasonic firmware flash also the aboot partition which has bootloader unlock enabled. without unlocked bootloader you could end with bricked device and the only solution is mobile upgrade q.
I did as you said and finally got bootloader unlocked, yey! Hopefully I don't have to go thought that process anytime soon. Thanks and thumps up!

1-You didnt wrote phch model do you have.
2-newer heard of this issue . Install the drivers from the eluga firmware app, reboot, turn off your device, connect device to computer, run the download form the eluga firmware app.

That is the point from my previouse question! If you flash TWRP, your bootloader is unlocked by default!

It looks like MM update dont include aboot with commands for unlocking bootloader. You have to use mobile upgrade Q PC aPP, or Panasonic eluga firmware flash tool (for 6045Y) to go back to 5.0.2. Then unlock bootloader, and flash update to MM (or when on panasonic firmware youhave to use mobile upgrade Q to go back to stock). When on stock, wat for OTA MM or flash MM from XDA thread.

First, you didn't say what device model number you have.
Next, not all devices can be unlocked and not all devices that can be unlocked can use the "oem unlock" command. Some devices use "fastboot flashing unlock" command to unlock bootloader.
Last, just because your device has the "oem unlock" option in dev settings, doesn't mean your device can be unlocked.

Have you tried doing a simple Google search for:
"Unlock bootloader huawei lua-lo2"
If there is a known method, that will find it, if it doesn't find anything then there is not a known method.

Can you please help me regarding this issue.. i am facing the same error 0x7000 after executing fastboot oem unlock command. The device asks whether you want bootloader to be unlocked.. then I press volume up to say yes.. then it gets failed with error 0x7000.
I have checked all precautions.. oem unlock is on in developer mode and all the drivers are successfully installed.
my device is lenovo A5.

Question Help unlocking bootloader

Hey guys,
I am trying to unlock my bootloader but it doesnt work, everytime I do the "Fastboot oem get_unlock_data" command, it says it failed to get unlock data.
I have unlock bootloader option in dev settings enabled and all drivers properly installed along with fully working sdk and fastboot tools etc. I have a couple xiaomi devices with different custom roms.
Previously I installed RETLA using tiny fastboot script cus i bought the phone in latin america but software channel says RETAR... Is this discrepancy the problem?
If not, anyone know why even though bootloader unlock option is on, the fastboot command to get the data fails?
Using getvar all i see the cid is 0x0000, i've read that having cid: 0x0000 is the problem, might installing the proper firmware: RETAR change this?

cid is 0x0000

Most likely you will have to forget about unlocking the bootloader.
Reflashing will not help you in any way.

Do you know why the cid is like that? Idk what has been done to it cus I bought it used. Any ideas?
Ty
The boot loader on your phone was blocked incorrectly and the system stopped starting.
cid: 0x0000 is a consequence of the boot loader working state recovery software.
It is now in a state oem-locked" as it was originally from the factory. But you cannot unlock the bootloader now. But, if I'm not mistaken, you can install firmware for any update region without having to unlock the bootloader.
