[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?

Can't unlock bootloader

I have a OPO Chinese 16GB version. When I bought it, it was running CM11S(Seller flashed it). Now I'm trying to wipe my phone and install cm-11.0-XNPH38R-bacon-signed-fastboot.zip on it. I have installed ADB Drivers on my Windows computer and when I type adb devices it shows me the serial number of the phone. And also when I type in fastboot devices, it shows me the serial number. But I can't get it to unlock the boot loader. When I type in the command, fastboot oem unlock, I can see the following message.
...
OKAY [ 0.002s]
finished. total time: 0.004s
But it does nothing after that. Even when I reboot, I can see all my previous apps, files etc. are there. It doesn't make any change. How can I get this phone to unlock the bootloader and allow me to install a custom recovery and let me flash the above file I have mentioned?

There are How-to's on this site. It's probably unlocked now. Try flashing a custum recovery in fastboot.

That means that the device was already unlocked. Where did you buy yours? Ali Express? Mine's from there and I have gone through what you're going through right now. No worries. Bootloader is already unlocked so you can root it already.

I bought that off of eBay. I have tried to flash a custom recovery but it doesn't seem to get installed as well. After I do it, I only see the stock recovery but when I run the command fastboot flash recovery recovery.img it gives me the following message.
target reported max download size of 536870912 bytes

But when I go to recovery, I only see the stock recovery. It seems like even-though the command are executed successfully on the computer, they are not applied to the phone. Any ideas?

Settings > Developer Options > Update CM Recovery (untick)
Then flash your recovery via fastboot and it'll stick.

Download the factory stock images on cyngn. Find it online and fastboot flash it. There's a good guide online in the general forums that shows you how to go back to stock

I got it working. I flashed TWRP on my phone and wiped the phone. Downloaded http://builds.cyngn.com/factory/bacon/cm-11.0-XNPH38R-bacon-signed-fastboot.zip , extracted the contents and flashed it with fastboot using the following commands.
fastboot flash modem NON-HLOS.bin
fastboot flash sbl1 sbl1.mbn
fastboot flash dbi sdi.mbn
fastboot flash aboot emmc_appsboot.mbn
fastboot flash rpm rpm.mbn

fastboot flash cache cache.img
fastboot flash system system.img
fastboot flash userdata userdata_64g.img

Hope this helps a newcomer like me. Thanks guys.

Hard bricked? Can't get into recovery, can't unlock bootloader

Hello,
I think my XT1541 (16GB/2GB Retail GB) with locked bootloader might be hard-bricked.
I was running the stock 5.11 firmware when I did the 6.0 update and since then my phone is stuck in a bootloop.
Motorola won't repair it because I had to replace the screen and the phone is out of warranty.
I can access the bootloader but if I select recovery mode the phone just keeps bootlooping and I can't get into recovery.
I followed the instructions here to flash a stock firmware using fastboot. All the steps complete successfully but after rebooting, the phone is still stuck in a bootloop and I can't get into recovery.
I wanted to install a custom recovery but I'm unable to unlock my bootloader because of this error:
Code:
(bootloader) Check 'Allow OEM Unlock' in Developer Options.
FAILED (remote failure)
Obviously I can't check that option as the phone won't boot.
So, is it hard bricked? Is there anything I can do to get my phone to work again?
Thanks a lot for your help!

How many system images do you need to flash? Sometimes there can be more than 6, sometimes there can be fewer.

If u are bootlooping when trying to enter recovery , then prolly the recovery is the issue. I'd suggest flash the recovery.IMG again and then proceed with flashing the rest of the .IMG files.

I tried that and it didn't work. When I try to go into recovery mode the phone keeps bootlooping.
One thing I noticed is that when I try to format cache or userdata I get this error:
Code:
$ fastboot format cache
formatting 'cache' partition...
Formatting is not supported for filesystem with type 'raw'.
FAILED ()

I think there might be something wrong with the file system in my partitions. How can I manually format my partitions?
Thanks,

man , if you really need recovery, type fastboot boot recovery.img . It will temporaily boot you into stock recovery. Wipe cache and data there

I was running 5.1.1 when I got the notification for the 6.0 update.
I've noticed that trying to flash 5.1.1 firmware with fastboot gives me errors (preflash validation failed) while the 6.0 work "fine" (i.e.: I get OKAY after every step but then the phone is always stuck in a bootloop).
Thanks!

DO NOT ATTEMPT TO DOWNGRADE BOOTLOADER.IMG OR GPT.IMG !!!!!!! DONT FLASH LOLLIPOP VERSION OF THOSE FILES ON A DEVICE RUNNING 6.0
plz tell me u didnt flash those files..

Well I wasn't sure what version I was running to be honest so I think I tried to flash the gpt.img from 5.1.1 at some point but it failed with the preflash validation failure. I've always only flashed the 6.0 firmware files.

Yes, no luck unfortunately.
I think I might have flashed the 5.1.1 bootloader after all - is there any way to recover from there?
Thanks,

Bump!
Does anyone have any other suggestion please?
Thanks,

Last bump
I'm going to sell this on eBay as non-working then unless someone comes up with a clever solution?
Thanks for your help!

Try flashing once more starting with the gpt.bin (that should hopefully take care of raw partition error) and skipping the bootloader altogether. Also, may be worthwhile to try mfastboot.exe instead of fastboot.exe.

I have this same issue, but I haven't flash 5.1.1 Files, I Only tried with 6.0 Brazil Retail.
I also tried to flash gpt to get rid of the "raw" partition, everything goes ok but still displaying that error. Anyone can help?

I got the same problem with my Moto E 2015... If I find a solution I will reply it in this topic..

Try "fastboot flash boot [img name]".

The correct command is
Fastboot boot [drag and drop the img]

Are you on Beta1, if so, you can't boot into recovery that way, you need to flash recovery using Magisk first.

No I'm not. I'm on 9.5.11

If you have root, try flashing the recovery installer with Magisk

This command is useless it won't work. Download the latest oxygen OS zip(full rom package not the incremental one), place it in your internal storage and update it via the local updater.
After the update is complete you can boot to fastboot and then the command will work i.e. fastboot boot imagefilename.img
Hope this helps

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]
writing 'recovery'...
FAILED (remote: Command not allowed)
finished. total time: 0.584s
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.

"recovery" changed to "recovery_ramdisk" now.
