[Q] wifi Xoom 3.1 unlocking bootloader error...

I've followed all the guides to a T. and my SDK is able to run nicely. However, once I've made contact w/ my device in 'usb debugging mode', tested the connection w/ "adb devices" in command prompt, and set the device to bootloader w/ the "adb reboot bootloader" command, and finally I give it the command to "fastboot oem unlock", I get an unknown error!! Please help. I have all the path variables set, and my SDK is running good, and has all the newest updates.
This is a link to a video I made of the problem. Please watch. It'll help if you can see the problem! just copy and paste - youtube.com/watch?v=2bROUZh7GRI
Thanks for your responses. I hope they come quickly!

just copy and paste the command from the OP's instructions. I used the new Clockwork in the thread and just renamed it... which method are you using. I just did mine last Thursday with no issues. I used this method http://forum.xda-developers.com/showthread.php?t=1078019
HTML:
adb reboot bootloader
fastboot flash recovery recovery-Tiamat-R4c-100611-1150-cwm.img
fastboot reboot
Make sure you have the latest fastboot.exe and if all else fails start from the beginning again. Now you are sure your fastboot is unlocked....

Did you try to do the fastboot unlock again

How did you manage to get unlock to work? Perhaps if you gave us more info on what you did?

[Q] OnePlus One - Unable to unlock bootloader again after relocking

Hi Guys,
Hope to get some help here.
So i unlocked the bootloader of my one plus one and installed supersu + Twrp recovery. All worked fine until i decided to relock the bootloader.
I've put the device into fastboot mode and executed "fastboot oem lock" with twrp recovery still in there.
Now i am trying to unlock the bootloader again using "fastboot oem unlock" to be able to flash the stock recovery and having issues.
output of commands:
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot oem unlock
...
OKAY [ 0.004s]
finished. total time: 0.005s
C:\Program Files (x86)\Minimal ADB and Fastboot>
After this it boots straight to twrp recovery. I then hit reboot system and go back to fastboot mode and run the below:
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery recovery
.img
target reported max download size of 536870912 bytes
sending 'recovery' (12260 KB)...
OKAY [ 0.389s]
writing 'recovery'...
FAILED (remote: Device not unlocked cannot flash or erase)
finished. total time: 0.404s
Anyone has an idea how i can unlock the bootloader again ?
Thanks
Vik

Would it let you reflash the stock factory image thru fastboot? Maybe if you could do that it would let you unlock again. And it would give you stock recovery.
Or else what about the option in developer settings to update the stock cm recovery when installing an update. Maybe you could install an official update thru TWRP and get stock recovery back?
Just throwing out ideas, hope you figure it out

I've documented ths same issue describe here: http://forum.xda-developers.com/oneplus-one/help/locked-bootloader-twr-rooted-t2820341
The solution: http://forum.xda-developers.com/oneplus-one/development/mod-reset-unlock-tamper-bit-t2820912

Hi YrrchSebor,
Thanks for the reply.. I already tried all that, even using adb sideload and keep getting same error as mentioned above. I'll try the solution lemonspeakers suggested later today and post the outcome.

Be careful if you updated your phone to XNPH30O OTA,
!!! Warning !!!
In the NEW OTA CM11S XNPH30O, the bootloader (aboot) img size changed....
We request all not to apply the unlocker scripts on the new bootloader , until we confirm/find the new bit position.
It might brick your phone and corrupt bootloader...

It won't work.. do not try it if you updated to XNPH30O using the OTA.

I ran this command:
Code:
fastboot.exe boot TWRP-2.7.1.0.img
But the next step does not work:
Code:
It will boot your phone into recovery once from the recovery image
stored in your PC temporarily
then you can flash the zip either by sideload or from sdcard...
I got:
downloading 'boot.img'...
OKAY [ 0.484s]
booting...
FAILED (remote: Device not unlocked cannot boot)

That's because you can't boot a recovery with the recent bootloader unless you're unlocked.

I never said to enter "fastboot boot", try with "fastboot flash" and the result will be better Please read and read again before saying that TWRP is not working.

[RECOVERY][TWRP][Unofficial][Port][ROOT] Ulefone T1

This is a ported TWRP that I put together from another MTK6757 recovery that was twrp ready. I have only used it so far to root my device. I am not responsible for any harm to your device.
1) Backup your phone.
2) Unlock Bootloader (!! YOU ARE WIPING EVERYTHING ON YOUR PHONE !!)
3) fastboot boot recovery-20170912-t1-twrp
4) Swipe modify system partition
5) Install desired root method (I installed Magisk here.)
6) You phone will be back to factory, with root installed.
Enjoy!

Succeeded
Thank you ^ ^
Open CMD (command prompt) and type the next command :
adb reboot bootloader (and press enter)
Now type the next command :
fastboot boot c:\adb\recovery.img (and press enter)
**I installed Magisk but magisk hide not wroking!!! **Why??

I only just got my T1 and this is my first time using it but under "Developer options" in settings of the device there is an option for "OEM unlocking". Googling that the first result says "OEM Unlock is a protective in Android Lollipop and later that is usually a step that users need to enable in order to officially unlock the bootloader of their device." Hopefully that helped.

Hello, I installed magisk and It works... But with this method "fastboot boot c:\adb\recovery.img (and press enter)" recovery is on PC and If I try "adb reboot recovery" the phone reboot on a black display and after I reboot in normal mode !!!.
And of course, the power+ vol up doesn't work.

Wonder when they will actually create a thread for this phone.

Did this work for you and have you had any issues with your device at all? This is my first MTK device so I want to make sure it's all good. Seems almost too easy compared to rooting and unlocking my Xiaomi devices

When I enter the cmd fastboot reboot bootloader, all I get when the phone reboots is "bootloader mode...." in the lower left corner. When I type fastboot oem unlock all I get it "waiting for device"

P8 Lite:Fastboot command (Failed: Command not allowed)

So i am having a problem while trying to install TWRP via ADB. When i am typing command "fastboot flash recovery recovery.img" i get this "Failed:<remote> Command not allowed" code.
I tried using cmd and Powershell with Administrator's right but the same thing happening again and again. I even tried to root the phone using in-phone programmes (Kingroot, Kingoroot, iRoot)in order to use Flashify and flash recovery through there and still nothing. OEM is unlocked and i can't really relock the phone since i dont have the unlock code anymore and Huawei doesn't support Unlocking devices anymore from her website to get a new one.
Things i did up to this point:
Enabled USB Debugging
Installed Huawei USB Drivers
Opened Powershell/Minimal ADB and Fastboot with Administrator
Typed command "fastboot flash recovery recovery.img"
Got this :
target reported max download size of 471859200 bytes
sending 'recovery' (23942 KB)...
OKAY [ 0.568s]

Is there any way of installing TWRP on this phone ?
Is there any method i can root this phone in order to flash TWRP from Flashify?

In huawei devices recovery named recovery_ramdisk, so fastboot command is different.
I suggest use huawei multi tool for flashing recovery or system gsi .

Since Oreo: Partition names have changed.
Use this command: fastboot flash recovery_ramdisk RECOVERY.img
"recovery" changed to "recovery_ramdisk" now.
