Question [Solved] Re-locking bootloader - no fastboot commands working - Lenovo P11

Hi everyone.
I´ve decided today that I want to re-lock my bootloader on Lenovo P11 tablet and I discovered no fastboot commands work on that.
I installed clean version of ROM from Lenovo Rescue and Smart Assistant (TB_J606L_S120217_210805_ROW) but still nothing works.
Normally i reboot to Fastboot and try "fastboot flashing lock" but i recieve:
< waiting for any device >
FAILED (remote: 'Unrecognized command flashing lock')
fastboot: error: Command failed
When i try others like "fastboot oem lock" i recieve:
FAILED (remote: 'Command not supported in default implementation')
fastboot: error: Command failed
Does anyone has any advice what can I do to relock bootloader?

1. enable developer option
2. enable oem unlock in developer option
3. boot to fastboot mode and run
fastboot flashing lock

Thanks @ong14 for your reply but as you can see above I already tried that...

If you're on chinese firmware, try "fastboot oem unlock-go".

Sadly I get this response for this command:
FAILED (remote: 'Command not supported in default implementation')
fastboot: error: Command failed
Is it possibly because of version of my ADB and Fastboot tools? I downloaded many versions (lastly directly from Android Studio) but it didn´t fix anything. @ong14, could you possibly upload the tools you are using?

Sorry for my last reply, it should be "fastboot oem lock-go".
AFAIK, if you're on global rom, use this "fastboot flashing lock".
And if you're on chinese rom, use this "fastboot oem lock-go"
I'm using an old minimal adb and fastboot.

It is totally OK, I am grateful that you are trying to help me at all.
I will try your old adb and fastboot tools and see what happens.
Sadly I don´t have much hope. I am on global rom and command "fastboot flashing lock" resulted only in:
"
FAILED (remote: 'Unrecognized command flashing lock')
fastboot: error: Command failed
"
I will keep you posted about my progress and what else I tried.

Well, sadly, still nothing. I tried everything I could think of. I even tried different PC, flash rom with QFIL even with stock bootloader. I still get the same response.
Did anyone else run into this problem?
Edit: After further investigation it seems that I shouldn´t be in the fastboot mode but in the bootloader mode. There i should try "fastboot flashing lock".
Sadly, I see my P11 in device manager only as unrecognized Android device and no drivers seem to change that. Tablet also isn´t visible in the "adb devices" or the "fastboot devices"
Does anyone pls have working drivers or should I continue trying fastboot mode?
Edit2: OMG, I finally solved it. Yes, i shouild be trying to lock the bootloader from the bootloader mode from the start. After I booted to bootloader mode, installed Lenovo USB drivers (https://www.mediafire.com/file/1bzfblquyofokgi/LenovoUsbDriver_v1.1.34.zip/file) and it finally worked!

My guy, you are brilliant. I wonder why the change from oem to flashing was done and were you getting sent to that fastbootd menu too? This worked for my 2020 Moto Edge and I don't know how much longer I would have needed without you.
Thanks.

Install RSA from Lenovo also works, and you can run rescue if you want to go back to 100% bone stock

Where and how do you get the drivers for this tablet? For some reason I'm stuck in (what I think) is the exact same screen on my tablet. It says fastboot... in the lower left hand corner and you can hear the disconnect chime come from my laptop every few seconds. I punch in fastboot devices and it's stuck in limbo, no error codes or anything.

Did you check device manager?

I didn't think I had to, when I plug in the tablet it pops up with the name and everything.

I'll try the Motorola drivers, is that going to solve the fastboot stuck screen?

Where do I go about getting the Motorola drivers?

hey mate. i had problem. now my Xiaoxin Tablet Pro 2021 having widevine L3 even i already lock the BootLoader and Stock Rom. how do i get Widevine L1 ?

thats where I have no clue what hell is going on, if I type in flash blah blah it says waiting for device
i have the same issue, I'm I reboot via adb and then my xoom reboots and says starting fasboot protocol support and just sits there. Any help or idea why?
answered my own question. This is because my device has not been unlocked yet.
I had to do the fastboot oem unlock found here.
http://forum.xda-developers.com/showthread.php?t=967065
Only thing I can suggest is to check to make sure you have your drivers installed and ready for fastboot. I think one of the commands you can throw at it is fastboot devices which should do the samething as adb devices but use for fastboot (but can't remember, been awhile since I've had to do anything with fastboot). If that is an acceptible command then you should see your device listed, if not then your computer isn't seeing the device which is why it's saying waiting for device.
You might also want to try throwing the fastboot oem unlock command again and see what happens (it's possible that you've never actually unlocked the xoom).
This is only a few suggestions I can give you for now as I'm not at home to try throwing some of those commands myself to confirm they're valid commands or not, sorry.
drivers are installed that's how I did the original unlock. and I'm sure I hit accept. I went through the whole process of losing everything when doing so. no dice on being able to flash . and the weird thing is this. when I type in adb reboot bootloader it reboots to the fast boot protocol screen but when I type in the info to flash the recovery I get the error of can't load
I'm having the same problem, I simply can't boot into FASTBOOT. I've got the latest USB drivers, I've updated ADB, but it just won't work. It just sits there telling me "Starting fastboot protocol support".
Very frustrating, nothing I do seems to fix it - I've even done a factory reset.
Edit: Now it won't even respond to "fastboot oem unlock", it just sits there saying "<waiting for device>" even though the device shows fine when I do "adb devices" and the device also shows in Windows. (Is this simply because the device is already unlocked)
Are you sure USB debugging is enabled?
Sent from my GT-I9000 using XDA Premium App
Yep, it is
Edit: By the way, if I do "fastboot devices" nothing is listed. If I do "adb devices" it lists the XOOM just fine.
Edit again: Just noticed that the OP also used the "rootmyxoom" process, which is exactly what I used and I'm having the same issues he's having... hmm.

Cannot lock bootloader

So I'm trying to re-lock my bootloader,
I already looked up how to lock the bootloader and you can do that by booting in to fastboot and locking the bootloader from there. My OP6 was rooted but I removed all root related applications, I even reinstalled android.
I tought it would be as simple as unlocking the bootloader, but whatever I try I can't get my device to show up in the command promt when using the "adb devices" command while in fastboot. I tried reinstalling the ADB, fastboot and OP drivers a couple times but it doesn't help. I tried everything possible but I can't lock the bootloader.
Could somebody please help me with this?

You have to be in fastboot mode ( power off phone, hold power and volume up til you see fastboot on screen) on your phone to do want to want, if you cant do it that way,you can try this tool, https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3798892 , it will return your phone to stock factory fresh. It will be back on 5.1.5 software. Good luck
in fastboot mode just type without quote"fastboot oem lock"

I can boot into fastboot mode (I said bootloader instead of fastboot, my bad), but the command promt does NOT show any devices, so I can't use this command. All drivers are correctly installed.
Did you enable USB debug?

Yes I did
And I tried updating to android P but now I can't even access fastboot!
[UPDATE:]
I can finally boot into fastboot again, the only way to do this was to first boot into recovery and restart to fastboot from there.
And my device is still not detected by adb in fastboot
u do fastboot devices not adb devices
I just tried doing this in a Windows 7 virtual machine, but it gives the exact same results, I really don't know what is cousing this
Then take tool all in one
Well.... Use msm download tool then.. Since you can go to fastboot, it will reset everything and lock the BL.

You should do "fastboot devices" in fastboot mode!
I see thay you're doing "adb devices" instead which is wrong.

All commands fail in fastboot

Hello everyone,
after unlocking my bootloader (on a Realme 5 Pro) to install TWRP and custom ROM, I am now stuck at trying to make fastboot do anything.
No matter which fastboot command I try, the phone won't execute it. I instantly get a "FAILED" and "(No error)" returned and the phone exits fastboot, showing some logo with a chinese message, as well as "press any key to shutdown" in the top left corner.
The only excpetions to that behaviour:
1. "fastboot devices" works as expected and recognizes the phone.
2. "fastboot boot [path to TWRP .img file]" sometimes gets stuck at "downloading boot.img..." indefinitely, sometimes it fails like all the other commands
3. "fastboot flash recovery [path to TWRP .img file]" gives an instant "FAILED", but the error message is "requested download size is more than max allowed"
I've tried re-locking and unlocking the bootloader, when unlocked both colorOS and fastboot recognize the bootloader as being unlocked.
I have no clue what to try at this point, hopefully someone can help me out?
Same problem here.
Mine is Realme 3 pro with the new version of realme UI, RMX1851, C.04, I have unlocked bootloader without downgrading it to color os 6, but now I cannot flash twrp in my device. After going into fastboot mode, after applying the commands, it says "FAILED" (remote: GetVar variable not found) and sometimes directly "ERROR"
The fix was an incredibly easy one, but I only found it/got the idea through a lot of googling... simply used a different PC (that I never used adb and fastboot with before), let windows search for drivers online, and BAM, it works!
Hopefully this will help someone in the future.
If you don't have more than one PC, I guess the best bet would be uninstalling all adb and fastboot related drivers.

Question Fastboot drivers not working

searching all over the internet on how get my computer to recognize my device in fastboot..
I already had universal adb drivers installed, along with android studio.. so adb worked out of the box. I tried to root, got to where I need to unlock the bootloader but no fastboot..
Tried reinstalling universal adb drivers, also tried a few other downloads from google with no luck on anything..
Searching the forums it seems like fastboot 'just works' for everyone else, so maybe something on my computer is messed up..idk
device manager just shows 'unknown android device'
my phone is oneplus 9 unlocked version, model LE2115
any help is appreciated

ok now I'm confused.. those drivers didn't work. following the root guide on here it says 'unlock the usual way''boot to bootloader''issue command 'fastboot flashing unlock''
so I decided to try rebooting to fastboot instead, which brought me to fastbootd
fastboot does recognize fastbootd, but the unlock command "flashing unlock" is unrecognized
So do I use bootloader or fastbootd to issue the unlock command?
if the latter, why would fastbootd not recognize the command?
the 'oem unlock' option is ticked on...

Make sure you enable oem unlocking in dev options first and reboot.Reboot to bootloader,issue command $fastboot flashing unlock..

I unzipped the file to my desktop, then tried installing driver through device manager, but no driver was found.. I then tried installing the driver with the "DPInst_x64.exe" file, but it says install failed with no other explanation
I tried just opening a command prompt in that folder, but with no driver installed, it still isn't recognized

Try one more thing. Install these and creat shortcut on desktop and try opening cmd in this. We gonna get you unlocked.
One last thing. You have also went into developer options and tic'ed "USB debugging on then ok on device when it asks if you wanna allow phone to communicate.
tried that, still nothing. usb debugging is on.
all I need is a working driver, everything else should be good..
one thing which i'm not sure if it's an issue, I'm using an old usb c to usb 2 cable, I'm not using the cable that came with the phone because my computer doesn't have usb c ports.. but adb and mass storage/file transfers work with no issue
Hate to say it, but it still COULD be your old USB cord even with file transfer and adb functionality preserved. I had a cord that did do file transfer but not adb. You should try another cord...
Here's another driver source to download:
Universal ADB Drivers
2 new cords, and also tried multiple driver downloads, but still nothing... i was really hoping to root this phone and it seemed so easy for everyone else, thats why i bought it.. but I guess I'm stuck with a locked bootloader...
I could try factory resetting windows or the phone, but would that even make a difference?
..rereading the root guide, at the beginning it says "if you're on global and want root, flash the eu boot.img" but I'm not sure if he means do that first or use that for the guide.. I'm assuming I need the bootloader unlocked in order to flash it first, but maybe not..
..also should I have just commented in the root guide post, instead of making a new post?..
I'm sure you've tried another usb port on your computer.
Last thing to try: another PC.
Shouldn't come to that, but that's where you look to be.
Got it!! Someone posted about the op6 not working either and the fix is turning off windows driver signature, not sure why but that worked for me..
Thanks, now on to root lol
I just had some serious fastboot driver issues when setting up my oneplus. Not sure if this helps but can you at least find the driver folder that was installed on your c:drive when you initially installed the drivers. Then check your device manager when your phone is in fastboot and update the device (usually under portable devices) through that path?
If you get a tampering /corrupt error when you do this you can disable driver signing in windows which is what worked for me thanks to this saint.

flashing pixel 2 without usb debugging

Hey guys, I need help flashing my Google pixel 2. It was off for a couple of months and now when I am trying to start it, its not booting without putting it on charge and even then it only shows the battery icon then the google icon and restarts (So a bootloop). But when I press and hold the power button and volume down key, it goes in the fastboot mode ( the one where all device information is shown with an Android Logo) (Pic att).
If I select Download mode, it just shows operation denied and if I select recovery mode then it goes to bootloop again. Also as far as I remember when I last used the phone, the usb debugging was turned off so please suggest what to do from here.
If you have USB debugging disabled with OEM unlocking off there's not much you can do. That's why I usually suggest if you're going to relock your bootloader keep oem unlocking enabled so you can flash the factory image if you run into problems. this has saved me a few times.
try downloading the platform tools and usb driver and running the unlock command, what message do you get? The first command you want to run is ADB devices to make sure that your device appears in the list and the command prompt. second command to run is fastboot reboot bootloader , If your phone restarts back into bootloader then you know you have the driver and fastboot /ADB installed and working properly. then go to the Android developer page and find the proper unlock fast boot command I think there's a different one for the Pixel 2.

Hey thanks for the update man. I know I should have kept atleast oem unlocking enabled. My fault.
Now I followed your instructions and the phone only shows under fastboot devices. But when I run ADB devices it comes as blank under list of devices attached. I still tried the fastboot reboot bootloader command but the phone just restarts with the battery charging icon flashing on screen and then going back into the fastboot mode. (pic of which I attached in the original post).
Any other ideas would be appreciated, else ill just take it to a service centre.

Mine shows blank also when running the devices command.
If you can run commands like "fastboot reboot bootloader" or "fastboot reboot recovery" etc and the device restarts, then platform-tools and driver is installed. I mean make sure you have the latest versions of both or else there's no point on going any further. An older version platform-tools will cause a bunch off issues so update that for sure.
what happens when you run any of these commands when your in the bootlaoder menu (where it says Fastboot and device state: locked) (after you've updated platform-tools, check the version by typing the command " fastboot --version" - 31.0.3 is the latest version)
fastboot flashing unlock
fastboot flashing unlock_critical
fastboot oem unlock
If you can unlock your device, you can flash recovery/bootloader image and go from there. But it doesn't look good.

Unfortunately none of these commands are working and yes I have the latest platform tools and drivers installed. Attaching image of the same.

yeah, it means the oem unlocking option is disabled in developer options. damn.
can you try logging into recover menu at all so you can update both boot slots A/B with the ota using adb update option in the recovery menu.
What about running a few fastboot commands to delete userdata and even switch boot slots. that Fastboot screen will show what slot you are booted in (either a or b). try switching slots and booting then?
fastboot --set-active=a (if you are in Slot-B)
fastboot --set-active=b (if you are in Slot-A)
After swithing slots, hit restart device and as soon as you see the Google Logo, hold volume down. If you can boot into Android, enable oem unlocking as soon as you can, don't even connect to wifi or whatever. Or try accessing Recovery mode after switching slots. Main goal is to try to access recovery to update ota and/or access Android to enable oem unlocking.
have you looked on xda for other fastboot commands to try? There's a few Unbrick posts on the Pixel subs - worth a try?

Okay so I tried switching slots. Currently active slot is A but it again shows error that slot chage is not allowed in locked state. Well was worth a try.
I tried almost everything to get into recovery menu as per my knowledge but cant. It just restarts back into the fastboot state or goes into bootloop.
I did a bit of searching before creating this thread but didnt found anything. Ill try again and see if someone has something similar.

download the full factory image (not ota) and extract it, and move the radio and bootloader images into platform tools folder and try flashing? But don't think you can.
Also, maybe try installing Skipsoft and see what commands you can execute from there? https://skipsoft.net/download/unified-android-toolkit-v1-7-2/
it supports the Pixel 2.
Not sure how the op in that thread above fixed his Pixel 2 with Skipsoft tool. His Device state said Locked in his screenshot on his post.
Also try draining the battery and see if it will boot into Recovery Mode at all. And check the other Pixel threads (like Pixel 3 XL) there's a few unbrick posts there also.
edit--try these commands
fastboot erase system
fastboot erase data
fastboot erase cache

Not sure how those users in the thread flashed the bootloader image since I didn't think you could if the device state is locked, but worth a try.
