This tutorial is based on the Lenovo Z5 Pro(L78031 - NO-GT version) tutorial By BadCluster
.Pre-Requirements
ADB means Android Debug Bridge, and it is software that you should always do have installed on your PC.
Pre-Requisite 1
Make sure that you have the drivers for your phone installed on your PC.
If not, you can download and install them from here https://devsjournal.com/usb-drivers-for-all-android-devices.html
Pre-Requisite 2
You must also install: Minimal ADB & Fastboot, you can download the software
from here https://devsjournal.com/download-minimal-adb-fastboot-tool.html
Scrolling through the page you will have 2 options: Download or Portable
(choose the one that you prefer)
Pre-Requisite 3
Make sure you have enabled 'USB Debugging' and OEM Unlocking on your device (read all tutorial before do it, because it will be wiped all data from the phone)
Settings -> Advanced settings -> Developer Options
Settings -> Advanced settings -> Developer Options
PAY ATTENTION: If you do not see the Developer Options menu you need to do this:
Settings -> Device Info -> tap 6 or 7 times on the 'ZUI version' entry
A pop-up should appear, telling you 'now you are a developer'
IMPORTANT NOTE: Before doing this, know that this operation completely reset your device and after rebooting, you will find the phone as if he had just left out of the box. So you'll need to configure your phone again and reinstall all apps.

Hi,
I followed the instructions and got "FAILED (remote: Serial number not matched)"
I checked and the SN in Device Info matches the one I've used to generate the file on their site.
Any help is appreciated, thanks.

Hey guys. Hope the new year will find you jolly!
So, here is my problem. My OneplusX which runs with SultanXDA's Cyanogenmod 13 with TWRP (Sultan-TWRP-onyx-3.0.2-3_2016-10-23).
I cannot make it boot since whenever I press the button to start, it shows the screen (check below) for approximately half a second, it vibrates for a tiny moment and then shuts dows and starts again and does the same thing in a loop.
The only way for me to stop this loop is unplug the battery from the phone's motherboard.
I cannot boot into TWRP and all I can do is boot into fastboot mode. I get the device recognised with fastboot devices, but that doesn't work, too, since it reports that the phone is locked.
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot devices
64875585 fastboot
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot boot recovery.img
downloading 'boot.img'...
OKAY [ 0.487s]
booting...
FAILED (remote: Device not unlocked cannot boot)
finished. total time: 0.490s
Ultimately, if it's not possible to make it work again, I would like to manage to pull some files from there, like images etc if that would be possible.

I had same problem once all I could do was reboot fastboot but since the bootloader was locked but luckily I found this thread https://forums.oneplus.com/threads/guide-mega-unbrick-guide-for-a-hard-bricked-oneplus-x.417648/ on oneplus forums this really helped hope this will help you
So, I will not try to use the Mega Unbrick guide yet since it deletes every user data and I will keep that as a backup solution.
I tried using the Skipsoft Android Toolkit in order to unlock bootloader etc, but so far nothing has worked.
The weird thing is that it reports the bootloader locked (even though it shouldn't be since there was already TWRP on it), but by the time that I try to unlock it, it says it's unlocked, tries automatically to get back to normal boot and at that time, we start bootlooping again.
Here's the Skipsoft Android Toolkit report:
Are you ready to start? Type y[yes] or n[no]:y
Device mode detected: Fastboot Mode
Device Serial Number: 64875585
Checking bootloader state..
Device bootloader state is: Locked
Do you want to unlock the bootloader? Type y[yes] or n[no]:y
When prompted, Press the Volume Up/Down button to select Yes on the screen, then
press the Power button to Unlock the Bootloader. If it is already unlocked this
will just be skipped and your device will not be wiped.
Sending oem unlock command to device..
Device bootloader is already unlocked so no data will be wiped
Rebooting back to Android..
rebooting...

Being in the same situation right now. Did you manage to come out of it?
You can try to reflash a TWRP on it. And then boot on it.
Or Mega unbrick guide

Mega Unbrick Guide doesn't start by flashing via Fastboot.
You need a recovery tool on your computer.

Yep, did that, all executed fine and situation changed from boot-loop into stuck at boot. Still only possibility is to get into fastboot.
Edit: Managed to get into recovery and sideload the original ROM there. Back on track

Lucky you. There was no way for me to get to recovery. Something was wrong there.
The only thing that really worked in the end was the Mega Unbrick Guide. I've got my phone back on track and working.
Glad you managed.
Hello everyone,
I've been googling this for the past couple days it's been driving me crazy. Stock 7 (I think), should have been unlocked but is showing locked.
1. My friend gave me the Nexus 9 which turned off one day, then wouldn't turn on again.
2. I plugged it in, and it turned on fine. Assumed bad usb port, he said keep it. I enabled developer options, then did "OEM [bootloader?] unlock" and "USB Debugging" toggles on (from memory, may not be right phrasing)
3. While trying to back up his data on it by ADB Pull, it would randomly stop. Using it, it would reboot unexpectedly.
4. So I went to Software Update.. bad idea in retrospect probably it rebooted during or something? It was fully charged and on AC power but I wasn't watching it.
5. I come back and it keeps bootlooping. Went into recovery, says "Device Locked" - Tried clearing cache, no difference. Tried sending bootloader unlock command with fastboot, says I have to delete all data to unlock.
The only lead that I have is that it might be possible to image TWRP to recovery, then boot into it so that I can get files off it (With OTG Flash drive or USB?) - I wanted to ask for help here first.
I did my best to search for this prior, but I've been out of the ROM game since 2012 cyanogenmod days.. Hope that it's possible to save my friend's data, and then also to flash a new ROM which will solve the reboot issue.. Thanks!
Boot to recover, then when you get the Android mascot with the belly open, press ( I think vol up plus power) to get to a functional recovery with ADB support.

Thanks GK,
After going into recovery mode, there's the android mascot with the belly open as you describe. Then, I do (VolUp+Pwr) and it produces this screen below, which I'm guessing people call "fastboot". When I'm there, my Win10 PC makes the "USB item attached" noise, and I can use fastboot commands, but adb devices won't show anything. Do you have any ideas?

I thought I could use the fastboot access I have to flash twrp, but I get the following error. I switched the "OEM Unlock" toggle, but i'm guessing that doesn't mean anything until I unlock the bootloader in recovery (which necessitates deleting all the files). I followed the directions on the twrp website which claim that root isn't needed, but I guess unlock is.
Code:
PS C:\Users\User Profile\Downloads\platform-tools_r30.0.1-windows\platform-tools> .\fastboot flash recovery twrp.img

You need to be in recovery for adb to work. The Android with belly open is recovery but you need to unlock it with a button combo. Fastboot won't work unless you unlocked the bootloader.
I may have the steps a little off for getting to recovery but I'm sure searching how to boot to recover for the Nexus 9 will find you the right steps. It's been a long time since I've used the stock recovery on this tablet.
For future bootloopers: Well in the end, I wasn't able to figure out how to pull files using the stock HTC Nexus 9 recovery. Since it was locked, I wasn't able to install or execute TWRP .img , and unlocking it meant losing the files. It was weirdly looping even in Recovery & Fastboot. I tried every mode, and different drivers in the device manager, but ADB couldn't connect. Maybe it's not meant to for security purposes.
If you're bootlooping even in recovery, try the following:
I gave up on trying to recover the data, and decided to just unlock the bootloader. booted to Fastboot (Pwr+Vol Down on start up, select Recovery, Pwr+Vol Up, should say "Fastboot") Then I used fastboot oem unlock, which unlocked the bootloader and Deleted ALL DATA. Then, I could flash TWRP, using fastboot flash recovery twrp.img. Once I flashed TWRP, I booted to twrp recovery using Pwr+Vol Up at boot, wiped all partitions. Then I went to TWRP Advanced -> ADB sideload. Issued adb sideload ota.zip, and this gave me a clean stock install.
Thanks gk for your advice.
Hi there! I need some help, I am trying to root my device and need a boot.img, but I cannot find a Rom for the x9 anywhere online.
This is my first time doing this, I got this phone just to mess around with rooting. But maybe I bought a bad phone for it.
If there are no Flash Roms online, what are the next steps? Can I use a Rom for the e9 which released alongside this phone? Sounds like it wouldnt work.. but IDK.
Looking for help from the experts ^^
Any help is appreciated.
Finally found one! Took over 2 hours to download a 2gb file O,O but it's finally done.
Now I am having problems getting into bootloader mode.
In developer mode with both OEM unlocking and USB debugging enabled.
Used the correct cmd prompt (adb reboot bootloader) but the phone just restarts.
I've tried restarting while holding the volume buttons.
VOL Down = Factory Test Mode, nothing works as expected there.
VOL UP = A boot menu letting me select from ~10 options, one of them is Boot to Bootloader. Selecting that simply boots normal, nothing special.
I have followed three guides:
How TO Root Vodafone Smart X9 Magisk without TWRP Recovery
If your Smart X9 is rooted using Magisk without TWRP Recovery. You can control a lot of features such as you can remove unwanted software.
www.getdroidpro.com
Vodafone Smart E9 Unlock Bootloader with Fastboot Method
How to unlock bootloader on your Vodafone with Fastboot Method. You can install custom ROM, custom recovery, kernel, flash all data
www.mobilewithdrivers.com
All seem logical enough, many similarities between them. I just cannot get into fastboot mode.
I've seen LOADS of threads with this same problem on this forum. And none of them have any solutions. So I think this is the end of the road. If nobody has figured it out .. then I am just out of luck I guess?

Hi @joke19 !
I havnt seen any of the guides mentioning needing a certain amount of buttons :O
How does that factor in - does that mean it cannot be rooted for some reason?

I'm using USB2.0 with the correct wires.
The phone is in developer mode with USB Debugging and OEM unlocking enabled.
I'm using the correct command lines. adb devices & adb reboot bootloader work as expected.
But none of these will work: fastboot devices, fastboot flashing unlock, fastboot oem unlock.
I just get < waiting for any device >
Can anyone help figure this out? I must be doing sooomething wrong. Everything online says its a driver issue, but then again, all the guides on how to fix that driver issue have been followed and completed. The first bullet with the image should also sort of verify that.
Praying some wizard out there has the knowledge I need to get this working! ^^

You must unlock the bootloader and then follow this steps: https://topjohnwu.github.io/Magisk/install.html
I have check and my phone can be unlocked, i have downloaded fastboot but i do not understand what to do next. I got to step 8 https://www.xda-developers.com/install-adb-windows-macos-linux/ i can see my phone in the command line, what to do next?
I cannot find the fastboot icon under devices and printers
I got to https://mobilewithdrivers.com/unlock-bootloader/sony-xperia-l3-32gb-3gb-ram i got it into fastboot mode but no commands works, fastboot flashing unlock, fastboot oem unlock. Unknown command, command not allowed.
Should i have a unlock code? I only see Xpeira L2 on the site for getting a unlock code, no L3 https://www.getdroidtips.com/unlock-bootloader-xperia-device/
It seems to be something wrong in developer mode, oem do not turn on, no green, it is just off.

Thanks. I cannot unlock the bootloader to try. I do not get the oem under development mode to work. It is only off. I can't get it on to unlock the bootloader.
Why not contact Sony ?

What Fastboot command did you run?
BTW: Install the suitable Fastboot driver provided by Sony, if not already done yet.
I tried
Use the Command Prompt window to retrieve your unlock key as described by your manufacturer. If you own a Motorola device run the command: fastboot oem get_unlock_data, HTC run the command: fastboot oem get_identifier_token.
Select the token which is spit out by the Command Prompt window and copy and paste it into the applicable box of the form on your manufacturer's website without any spaces.
And: fastboot -i 0x0fce oem unlock 0x07B7BFEA7AC879F0 https://www.getdroidtips.com/unlock-bootloader-sony-xperia-x-f5121f5122/
I downloaded android_winusb.inf were should i add it?

I tried fastboot.exe -i 0x0fce oem unlock 0x and got FAILED, command not allowed. I did only find Sony L, L1 and L2 on sony oem https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/#unlock-code can it be that? I remeber i had a Sony Xperia X code.
I also tried fastboot flashing unlock, FAILED unknown command. with fastboot devices i got my phone visable.
For the last few days, I've wanted to install lineage on my phone, because the stock OS is very bad and uses 90% of the ram on idle, and it is full of bloatware and stupid issues. and the UI is not very good.
This whole post is long explaing about my failed efforts, you should read it all to avoid telling me stuff that i tried already.
What i tried?I tried using the basic way, for any android device. I got adb, and fastboot, and did the required steps. When i get into fastmode (after a whole day of fixing why my device is not detected by fastboot by the way), i tried many commands, they all DO NOT WORK in a confusing way, they are not recognized by the phone.
The following are the commands i tried, the response is always the same.
Bash:
fastboot oem unlock
fastboot flashing unlock
fastboot unlock
fastboot flashing unlock_critical
fastboot flashing get_unlock_ability
fastboot oem device-info # Yes! even this doesn't work...
And all of them give me the EXACT same response
Bash:
FAILED (remote: unknown command)
finished. total time: 0.002s # The time changes obviously
Ok then i got accross this post. According to the post, i had to use their fastboot. Which.. did not work, because it was stuck at < waiting for device >.
But i did not give up and i looked a bit through github, and i found this repository. I tried it and hopefully it detected my phone. However, the commands mentioned by the post, also gave me the same output of the previous commands, so it was not helpful.
Attempts #2So after this massive and confusing failure, i decided to try again, my friend told me i can use mediatek flash tool (stuff that i can barely understand currently) to flash TWRP, and use it to flash lineage. (Note: The Processor is MT6768)
So. i did a bit of research and i tried a few tools, for example TFTUnlock, SP Flash Tool. We managed to get the scatter file, and it should have worked... but it never did
So the problem with them is when i tried the fastboot method in TFTUnlock, it would try but also get unknown command, even the get device info button had the same problem. I tried the BROM Unlock which did not end up working, because the phone is probably not detected, when i plug it in (even while holding VOL+ and VOL-) i just hear window's sounds about device connection (actually multiple) then it continues charging, as if nothing happened. the application was still waiting for device. (and yes i got the drivers installed, and i had testmode on with driver enforcement disabled).
Wait but only one app did something different. The Smart Phone flash Tool had a special error when i connected usb (even if i do not hold VOL+ and VOL-) i had a special error, instead of just stuck at waiting. here's the error:

Other Notes
I tried both Windows 10 and Windows 11
I tried Fedora (fastboot method) and i got the same results
Flashing with fastboot will end up in error Verify State Locked
fastboot getvar command actually gives an output which includes some information, in which says that the bootloader is locked.
I did not forget to enable OEM Unlocking, in case this is on your mind
I had kaspersky on my phone which gave me a weird warning about a firmware change (although i did not success in anything). Here's the screenshot
Thanks in advance for the absolute masters who will help me get this done!
To unlock this phone's bootloader this command is the correct one
Code:
fastboot bbk unlock_vivo
If you get a confirmation message on your screen, reply in affirmative (‘Yes’, ‘I agree’, Unlock the Bootloader’, etc).

I tried that, it says unknown command, as i mentioned already
If Fastboot returns
FAILED (remote: unknown command)

then the Fastboot driver you use is a wrong one, means not suitable to phone. Point.

Interesting, but why would they provide me that? I mean, I'm not a technician or a shop I'm just a user trying to improve my personal phone
