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is both LOCKED and ENCRYPTED with a secure boot key, that cannot be unlocked without the AES key from ACER which they "do not publish", hence when using nvflash I get the error: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.

I recently purchased 2 Asus TF103C stocked with Android 4.4.2 and running on an Intel processor. I'd like to load a custom OS/ ROM to them for work however I have not had any success finding a process that allows me to do so. I have managed to root the tablet successfully but that is the extent of my accomplishment to date. I understand that this is a fairly new device and not much has been uncovered yet to achieve this task. Asus is also hesistant to release an unlocked bootlooder update. If anyone is aware of a process whether through adb or the likes please raise your voice to help the community out on this one.

Before following steps bellow mentioned don't forget to install USB and ADB drivers
Also download minimal ADB and Fastboot tools ( for links use google search its easily available)
Configure your compute for fastboot Enable USB debugging on the device.
Connect the device to the computer through USB.
From a terminal on a computer, type the following to boot the device into fastboot mode
$*adb*reboot bootloader
Once the device is in fastboot mode, verify your PC sees the device by typing*
fastboot devices
If you don't see your device serial number, and instead see "<waiting for device>",
fastboot is not configured properly on your machine.
If you see "no permissionsfastboot", try running
fastboot as root.
From the same terminal, type the following command to get info of the bootloader:
fastboot oem-info
To unlock type
fastboot oem unlock
And press enter
May this will unlock your boot loader in general

Hello, I tried your command suggestions to unlock the bootloader and they failed. The command 'fastboot oem-info' does not return anything and 'fastboot oem unlock' returns RESULT: FAIL (unkown OEM command) on the tablet and in the cmd window. Thanks for the suggested attempt nonetheless.
Still having this problem
fastboot oem unlock fails on the TF103C and it says RESULT:FAIL(unknown OEM command). It would be great if Asus could release a tf103c_unlock.apk utility like they have for other Asus tablets (for instance the TF701T has tf701_unlock.apk which works).
Asus, please help!
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.
Hello there!
I was on Sultanxds Custom rom + kernel and decided to flash another Rom. Therefore i wanted to update my TWRP to Version 3.0.2.0.
So i went into fastboot, connected my phone to the pc as always an ran the comand: "fastboot flash recovery twrp-3.0.2-0-onyx-20161116-113742.img". I got the message: "FAILED (remote: Device not unlocked cannot flash or erase)"
So i checked for oem unlock and this was the message i got.
"(bootloader) Device tampered: true
(bootloader) Device unlocked: false"
I just dont understand why the bootloader is locked... how is this even possible but anyways so i tried to just normaly reboot the device. But now i see the 1+ logo for 1 sec and it vibrates. And then it turns black again and I see the logo again and again...
But i'm still able to enter fastboot mode and i can send command from my PC. Can anyone tell what steps i have to do to make it bootable again? (is this a hardbrick?).
Thx in advice!
I just followed the hardbrick guide and i'm now on stock OS. For some reason the bootloader was locked again... problem solved and this thread can be closed...
cmd with adb...
And I followed the steps meticulously - unlocked bootloader etc, but I get to the "writing recovery part" -
And it says FAILED (remote not allowed in locked state)
I don't get it! =(
I have unlocked bootloader, I have installed drivers, I did EVERYTHING...
Any advice?
In dev options it says my bootloader is unlocked however when I type:
fastboot oem unlock -
It comes up with options to unlock press vol up
but volume up button does not acknowledge me pressing it!!!
Please delete this thread no longer valid
thanks
Hello,
I have a OnePlus 7T Pro (codename "hotdog") that is currently in a non-working state. My goal flash my magisk boot.img which I created, however I accidentally locked the bootloader. Unfortunately, I'm currently stuck and unable to progress.
Here is what I've tried:
I attempted to unlock the bootloader via fastboot with fastboot oem unlock, but received a FAILED (remote: Flashing Unlock is not allowed) message. I understand this usually means the OEM Unlocking option in the Developer Options isn't enabled.
The problem is that I can't access the Android OS on the device to enable OEM Unlocking. The device boots directly into Fastboot Mode and I can't navigate anywhere else.
I tried to flash the stock firmware, but I received an error message stating FAILED (remote: Flashing is not allowed in Lock State). This indicates that I can't flash files to the device while the bootloader is locked.
In short, I can't unlock the bootloader because I can't enable OEM Unlocking, and I can't flash the stock firmware because the bootloader is locked. I'm stuck in a loop and unsure how to proceed.
Any help with this issue would be greatly appreciated! I'm open to all suggestions and willing to provide additional details if necessary. Thank you in advance for your assistance.
Best regards,
The only thing I have is that my device is shown as connected in cmd and the command list available, other than, the ability to flash
