I'm trying to upgrade my SX66 to WIN2k5 and I can't seem to figure out how to unlock the boot loader.
I'm using mtty and using the l d:\unlock\him.bin command.
I get the following error: Not allow operation!
Any suggestions?

Is it possible to unlock the bootloader on an Acer Iconia a200, if the tablet will not boot into Android?
While in fastboot mode, I enter FASTBOOT OEM UNLOCK, then I use the volume button to select the unlock icon and it tells me this:
SetUnlockedMode: Error occured while unlock the device ...
Fastboot: Failed to set unlock mode
Somebody please help
I think I have figured out what's going on. From what I've gather from other threads, this Acer A200 tablet has a bootloader that is both LOCKED and ENCRYPTED with a secure boot key, that cannot be unlocked without the AES key from ACER which they "do not publish", hence when using nvflash I get the error:
Nvflash started rcm version 0X4 Command send failed (usb write failed)
And when using Fastboot OEM UNLOCK command and I select the unlock icon I get the error:
SetUnlockedMode: Error occured while unlock the device ...
Fastboot: Failed to set unlock mode
So this a200 tablet which boots up into an "encryption unsuccessful" message and now cannot even access the microSD card, the only option is to flash a new OS image, but that can't even be done because the bootloader is locked and encrypted, and nvflash can't be used to flash an unlocked bootloader for the same reason. Only solution is to sell this thing or send it to Acer.
Am I correct ?
stack in APX mode
I've the same problem bro. I think the only way is sell this Acer Iconia.
Hello Everyone,
I would like to ask if there is another way to unlock my Zenfone 5(WW_A500CG) bootloader without using the asus bootloader unlocker apk file? Because my phone's in a bootloop and i am trying to flash the WW.2.21.40.44 Firmware and always get the "signature verification failed" error and whenever i run the command "adb devices" my phone's wont show up.
I got error when unlocking bootloader with flashtool (0.9.20.0)
FAILED (remote: Command not allowed)
I also tried with fastboot on commant prompt and got the same error.
And created a folder with my device's serial and put ulcode in it (folder is at flashtool/custom/mydevices) and got the error bootloader cannot be unlocked offically.
Rooting status in my device's service mode says unlock bootloader allowed:yes
My device is E6803
Is there anyone to help?
Any help?
Do you have OEM unlocking on in developer options?
Yeah man, I have. And that was the problem. Thanks for your help
So I have an unlocked XPERIA 1 III. I was trying to relock it (for software updates) and couldn't. I first tried going to the fastboot menu (adb reboot fastboot) and tried using fastboot oem lock. This resulted in a command not supported in default implementation error.
This is not a surprise as I had the same problem when I tried to unlock my phone. I then did adb reboot bootloader. When I unlocked my phone this was the solution to the problem however now when I reboot to bootloader, I get a black screen or I just boot into the OS. neither will accept fastboot commands.
Anyone have a clue whats happening.
If it is relevant.
I run Riru, LSposed, Magisk, Xposed Edge Pro... OFC I am rooted (considering I am using these apps... yeah)
Plz help
Try fastboot flashing lock 0x <your bootloader unlock code>
After following the unlocking guide i was able to unlocking it without much hassle and crossflash my att v60 to EA. However, my fingerprint scanner does not work. I followed the same guide listed on the bootloader unlocking thread to recover the fingerprint scanner functionality but that didn't work. Reading a bit into the thread I found one of the guys was able to recover fingerprint functionality by relocking the bootloader back.
I've tried with fastboot oem lock and fastboot oem relock and they give me this mssg:
FAILED (remote: 'Unable to open fastboot HAL')
fastboot: error: Command failed
Any solution?
Fastboot oem unlock again. Notification your devices unlocked. After. You write Fastboot oem lock. Done. I need file QCN to help my phone
