i get this. but im trying to do it on my deceased Aunt's tablet to give to my cousin. I had already deleted her google account per her sisters request before they had an issue with the tablet and i needed to reflash it. now im stuck on FRP and can't get passed it properly, so that play store can work. its an asus z301mf tablet so i thought it would be similar and maybe these instructions would work.

Hello
I have a problem when I want to unlock my nexus 9.
First I have a problem because my tablet freezed.
I have made a factory reset, then google said me : used the first account to use your tablet" but I lost this account
So I want to flash my tablet.
to do that, I use the tutorial on HTC site. on step 5 they say:
type adb oem unlock
but the CMD windows just say:
<waiting for device>
then I try to show devices with adb device but my window don't show device.
to do those step my tablet was in recovery more "fastboot usb"
can you help me?
thanks
Jack
@jackvig Looks like you encountered Factory Reset Protection!
You can not use adb commands while in fastboot mode! "fastboot devices" should list your device.
And the command to unlock is "fastboot oem unlock" not adb!
Plus you won't be able to unlock the bootloader unless you have selected the option to do so in developer options, since you have factory reset that option may have been turned off even if you set it previously.
Your going to have to try and remember your account password to make the device usable.
Depending on what version/patch of the rom your device is on it maybe possible to Bypass FRP, google it.
If your device was on a very recent patch level, no bypass trick will work.

thanks @corkiejp for your reply
I agree with you for fastboot instead of adb but the result is the same.
I cannot go inside the tablet to change parameters
Some forum said that I can Unlock in recovery mode
Is it true?
when my tablet is in recovery mode (On/off + Vol Up)
the tablet show me device state : locked
I am in state HBOOT
the on my computer I do that
C:\Users\maison>fastboot oem unlock
...
(bootloader) ability is 0
(bootloader) Permission denied for this command!
OKAY [ 0.015s]
finished. total time: 0.018s
after I go in FASTBOOT mode then :
C:\Users\maison>fastboot oem unlock
< waiting for device >
what can I do to have the Key to unlock
No you need fastboot mode to unlock the bootloader!
Is the command "fastboot devices" listing your device. If not check your drivers for your device.
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot devices
HT4B6JT00881 fastboot
after that i try :
C:\Program Files (x86)\Minimal ADB and Fastboot>adb sideload volantis-ota-n9f27m-ad1aee0f.zip
loading: 'volantis-ota-n9f27m-ad1aee0f.zip'adb server is out of date. killing...
* daemon started successfully *
serving: 'volantis-ota-n9f27m-ad1aee0f.zip' (~0%) * failed to read command: Invalid argument
i think tablet i now connected to computer
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem unlock
...
(bootloader) ability is 0
(bootloader) Permission denied for this command!
OKAY [ 0.011s]
finished. total time: 0.014s
As suspected the option to unlock is not selected in developer options.
If your successful in sideloading an OTA image in recovery mode (not fastboot mode), you will still encounter FRP on booting the device.
Edit: - As said before ADB commands do not work in fastboot mode. And fastboot commands do not work in Recovery mode!
As said before your only hope is to remember your account and password used (or the very last account you used on the device might work).
If you haven't updated the rom in the last year, you maybe able to use FRP Bypass trick.

You should not have factory reset if you do not know the account password. It is protected by "factory reset protection". To prevent it from being used if it is stolen. You are most likely going to need the password for the account that was logged in when you reset.
Flashing is not going to help. And as mentioned previously, you cannot unlock the bootloader now since you cannot go into developer options and turn on oem unlocking.
Hello, i have my phone Huawei P20 Lite wich is bricked with Phone Locked and FRP lock. I tried to write recovery with fastboot but always receive 'Command not allowed'. It's because my bootloader isn't unlocked...
when i want to power on it's stuck on 'Attention! Please install the update again'
If anyone know how to solve that, please leave an answer there!

Hallo there
Ok! So you can't really have an unlock code? Cause that would help a lot more... Anyway as for now from all cases I have seen you are telling me this is the hardest one. Altough there is one more chance that you should try.
If you have the stock recovery .img or a TWRP recovery .img you might be able to boot to it and do a hard reset which fixes your issue.
First download the adb tools from here:
https://dl.google.com/android/repository/platform-tools-latest-windows.zip
Then extract it to a random folder.
After you have the stock or TWRP recovery .img just copy it to this folder and open it.
If you don't have the stock recovery, I have a link to it here:
https://mega.nz/#!SR9RzKST!dhXS0yC-p_SvWu-SYYLaop1aRFzSulLVrnSXCVVJiGI
Then press shift + right click on the mouse, it should show an option called "Open a Powershell Window here in case you have Windows 10, or "Open a CMD window here" (on windows 8 and below) click that and a window will appear.
Next, if you are on windows 10 and the window says Windows Powershell type ".\fastboot boot imagenamehere.img" if not and you are on Windows 8 or below type "fastboot boot imagenamehere.img".
Where "imagenamehere" is your image name such as recovery.img or twrp.img or usually on this stock recovery recovery_ramdisk.img.
It should boot into recovery
That way you can factory reset if on stock recovery of course.
Either way you gotta lose all your data right now, there's just no way around it without losing data.
Cheers and best of hopes,
AS

Yeah you are right, my bad :/
I have a simple one, have you tried "fastboot reboot recovery" via the same command line as well? I know it's obvious but that should work for you...
If it doesn't please send me the error code.

I'm also having almost the same issue. My p20 lite is locked to Japan AU network and frp lock but it's not bricked. I want to use it here in Philippines that's why I'm planning to install a stock rom which will work here. Can you help me?
Hello, I have the exact same problem the guy above has, and I tried "Fastboot reboot recovery" and it still didn't work, I believe because of my cellphone. Do you have any more advice?
contact me i will try help
Hi kikson112!
If You are able to help in such problem I would like to ask You for help as well.
My case look similar.
My P20 lite with no reason (nothing I know) got locked . the screen is black and when I try to unlock it shows only time and weather in uper right corner. It looks like it would stuck in flipcover mode but I never had one.
I tried to reset it , reboot it but nothing help.
I tried to connect by Hisuite to download My data but it is not in debugg mode so I cannot connect.
During reset it looks like it is not loading the system.
When I connect my bluetooth headset it connects.
It is playing the alarm in the morning.
But I cannot do anything. The screen does not respond.
Any ideas what could I try to get My data would be apprieciate.

hi, for rescue data use converter to connect a mouse in usb port should work, in this case posible digitizer can be just broken, try download software math to ur phone and write it over sd card by 3 buttons (vol - vol + pwr) and post here if any changes
Umm, you can try to get Huawei to do it or youcan buy an unlock key to flash the stuff.
I think there is a special Huawei Flash mode but I don't remember how to access it anymore because I was a Huawei employee and I knew how before but I forgot. Sorry!

is fastboot working and upgrade mode ?
Dear all,
I have made numerous attempts to unlock the bootloader of my Wiko U Feel Prime, but to no avail.
(My goal is to flash TWRP, root with Magisk and install LineageOS.)
USB debugging and OEM unlocking are enabled in the developer settings.
ADB recognises the device. When I execute adb reboot bootloader, the device reboots, and doesn't get past the "powered by Android" screen – but is nonetheless found by fastboot when I run fastboot devices. Seems like the USB drivers are functioning properly, correct?
Now, when I run fastboot oem unlock, I get the following response:
Code:
...
FAILED (remote: unknown command)
finished. total time: -0.000s
The command fastboot flashing unlock gives the same result.
Moreover, fastboot getvar all displays no unlocked variable. The command fastboot getvar unlocked yields
Code:
unlocked:
By the way, this phone was shipped SIM unlocked.
I've spent hours looking around the web for solutions, but everyone (including guides specifically written for Wiko U Feel Prime) simply says "unlock the bootloader" as if it's a trivial task. And I've run out of ideas. Could anyone help?
Thank you very much.
I cant install stock rom, when i try install stock rom with miflashtool it says (FAILED (remote: Flashing is not allowed for Critical Partitions)
I know its need this command (fastboot flashing unlock_critical) but when i tray this its says (FAILED (remote: Flashing Unlock is not allowed)
plz help:crying:
Absolutely nothing you can do now. You have to enable oem unlock and USB debugging from developer options before trying to flash anything.
Only way to recover is by using a paid service online who will remotely recover the device through edl mode and a verified mi account.
Or you can bring it to a service centre to be fixed.
You will have to Google such paid services as it is against forum rules to promote as such
Hello there,
A newbie here, trying to unlock a TCL 20B (6159K) phone.
Android 11, November 2021 security patch (MTK Easy Su doesn't work with that, reportedly some vulnerability was patched), fastboot accessible but acting weird.
1. Got fastboot from here.
For some reason it doesn't understand the -i option, but connects with the only phone I'm trying to unlock attached anyway.
VID is 0x0e8d, btw.
2. Got adb from don't remember where about a year ago (for my previous Lenovo phone)
3. Unlocked the Developer Options
4. Checked "Allow bootloader unlock" and "Enable USB debugging" options there (not sure how those are named exactly in English, but I 100% guarantee, I've checked the right ones)
5. Sent phone into fastboot with
Code:
adb boot bootloader
6. Checked the unlockability with
Bash:
fastboot flashing get_unlock_ability
(bootloader) unlock_ability = 16777216
OKAY [ 0.005s]
Finished. Total time: 0.006s
7. Tried to unlock the thing, but
Code:
fastboot flashing unlock
FAILED (remote: 'not allowed in locked state')
fastboot: error: Command failed
and
Code:
fastboot flashing unlock_critical
FAILED (remote: 'not allowed in locked state')
fastboot: error: Command failed
8. Searching here, on XDA forums revealed there's no TCL 20B sub-form.
9. While there are tons of topics on not allowed in locked state, none of those helps.
fastboot oem unlock is seemingly an old way to do things (TCL 20B is a rather new device released WAY past 2015)
TCL is an Alcatel device, not a Xiaomi or some ZUK one, to require an account (haven't found anthing on "alcatel account")
trying to load some recovery from PC that might work failed as well (for the same reason)
Code:
[/LIST]
./fastboot boot twrp-3.6.1.img
Sending 'boot.img' (8932 KB) OKAY [ 0.212s]
Booting FAILED (remote: 'not allowed in locked state')
fastboot: error: Command failed
I've read some TCL 10 phones don't even have a fastboot, but TCL 20B clearly does.
Any Ideas how to unlock the bootloader?
P.S. Maybe a new sub forum for 20B? This got placed into the "TCL 20 5G" one, which doesn't seem right.
EDIT:
Ok, have found how to proceed on my own.
Even rooted the thing.
Go here https://github.com/bkerler/mtkclient, grab the ISO, backup, install patched magisk, patch the boot_a, flash patched boot_a and empty vbmeta_a, erase metadata, userdata and md_udc. Reboot, reinstall pathched magisk.
Don't lock the bootloader to avoid red state.
Huge kudos to mtkclient devs
Hello, i been trying to root my tcl 20b (6159a) but i cant figure how, i follow the instructions of mtkclient. Install it in windows, python, mtk repository, all the process, but when i try to replace boot_a.img it doesnt work from the cmd command, but in the python mtk_gui i can replace boot_a.bin and erase vbmeta_a.bin when i do it from there the cellphone keep in bootloop, i can fix the bootloop but cant root it. If u read this, can you plz be more specific with the steps, and made a little tutorial, its not necessary images or video just some more in deep info how you achieve root, thx
