a question, can it be the universal drivers or does it have to be the device itself?

When I try to put it on bootloader mode it fails.
Follow the steeps I've done:
1. Turn On USB Debug mode and OEM Unlock at Developer menu.
2. Plug in and do adb command "adb devices"
3. When appear the list with my phone I do the command "adb reboot bootloader"
But when it restarts it goes to system and not to bootloader screen.
Ive tried also "adb reboot fastboot" and "adb reboot download" but the same happens.
@diego998kk
Press and hold the volume down and power buttons until the LG logo appears, then release them. If this doesn’t work, you may have to release the power and volume down buttons for a second when the LG logo appears, then re-press them until the bootloader shows up what may take some seconds.

hi guys....today i rooted my moto e with the help of this site.....after rooting was completed my phone showed warning bootloader unlocked but after it started i checked with root checker app and it shows my phone is not rooted....so i tried to repeat steps of rooting........but when i type command "fastboot oem unlock 'unique key'" it says that my device is already unlocked......i dont know what to do now to root it properly......pls help....thnx in advance
i only did these six steps.....
1.) Put your device in fastboot mode (power off, then press the power and volume down buttons simultaneously).
2.)Open Command Prompt on androidsdk/platform-tools/ (Hold Shift and right click and press open command window here)
Connect your Phone to PC
3.)Type this in the CMD prompt window - fastboot oem get_unlock_data
You will get a return string. Copy it. [Right Click-Mark- Mark the text by pressing the shift key-Now press Ctrl+C]
Paste all the lines together in a notepad. Remove the empty spaces.
4.)Now go to the Motorola Site.Sign in using your Google account or Motorola ID. Scroll down the page and paste the copied string in the field at step #6. Then click on ‘Can my device be unlocked?’, after which a "REQUEST UNLOCK KEY" button will appear at the bottom of page. To get your unlock key, select the ‘I Agree’ option. Note: You will receive an email with your Unlock Key at the email address you used to log in there. Important – Copy the 20-character key that Motorola sent you via email. Make sure your device is connected.
5.)Then in CMD type: fastboot devices (To check your device is connected)
6.)Then type: fastboot oem unlock UNIQUE_KEY

DISCLAIMER
Modifying or replacing your device's software may void your device's warranty, lead to data loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk. No one affiliated with the CyanogenMod project is responsible for your actions. Good luck.
NOTE
- If you are not using a Verizon Wireless branded device on Verizon Wireless, you must follow the steps below to reboot into bootloader and then enter fastboot oem config carrier vzw to ensure proper data operation.
- Unlocking the bootloader on a Nexus device will automatically wipe all device data.
- Some ROMs overwrite recovery at boot time so if you do not plan to immediately boot into recovery to install CyanogenMod, please be aware that this may overwrite your custom recovery with the stock one.
INSTALLATION
UNLOCKING THE BOOTLOADER
- Make sure your computer has working fastboot and adb.
- Enable USB debugging on the device.
- Connect the device to the computer through USB.
- From a terminal on a computer, type the following to boot the device into fastboot mode:
$ adb reboot bootloader
Click to expand...
Click to collapse
- Once the device is in fastboot mode, verify your PC sees the device by typing fastboot devices
- If you don't see your device serial number, and instead see "<waiting for device>", fastboot is not configured properly on your machine. See fastboot documentation on cyanogenmod website - If you see "no permissions fastboot", try running fastboot as root.
- From the same terminal, type the following command to unlock the bootloader:
$ fastboot oem unlock
Click to expand...
Click to collapse
- A disclaimer will display on the device that must be accepted. Use the volume keys to cycle through the options. Pressing the power button should confirm your selection.
- If the device doesn't automatically reboot, reboot it from the menu. It should now be unlocked. You can confirm this is the case if you see an unlocked icon at the bottom of the Google boot screen during reboots.
- Since the device resets completely, you will need to re-enable USB debugging on the device to continue.
INSTALLING RECOVERY
- Make sure your computer has working fastboot and adb.
Download recovery -- you can directly download a recovery image using the link below, or visit clockworkmod.com/rommanager to check for the latest version of ClockworkMod recovery for your device (if your device can be found there).
Recovery: openrecovery-twrp-2.8.4.0-shamu.img
md5: fc904a1d1d49d1797ad62bb1cb4e6775
Click to expand...
Click to collapse
- Connect the Nexus 6 to the computer via USB.
- Make sure the fastboot binary is in your PATH or that you place the recovery image in the same directory as fastboot.
- Open a terminal on your PC and reboot the device into fastboot mode by typing
adb reboot bootloader
Click to expand...
Click to collapse
or by using the hardware key combination for your device while it is powered off.
- Once the device is in fastboot mode, verify your PC sees the device by typing
fastboot devices
Click to expand...
Click to collapse
If you don't see your device serial number, and instead see "<waiting for device>", fastboot is not configured properly on your machine. See documentation on cyanogenmod website
If you see "no permissions fastboot", make sure your UDEV rules are setup correctly.
- Flash recovery onto your device by entering the following command:
fastboot flash recovery your_recovery_image.img
Click to expand...
Click to collapse
where the latter part is the filename of the recovery image.
- Once the flash completes successfully, reboot the device into recovery to verify the installation. Boot to recovery instructions: Hold down the Volume Down button while booting, and use the menu to select Recovery.
INSTALLING CM12
- Make sure your computer has working adb.
- Copy zip to the root of /sdcard:
- If you are not already in recovery, boot to recovery mode now.
- Hold down the Volume Down button while booting, and use the menu to select Recovery.
In Team Win Recovery Project, select menu choices by tapping on the appropriately labelled button.
Optional (Recommended): Select the Backup button.
Select Wipe and then Factory Reset. If you're getting an error formatting /data, try format /data and /data/media from the Mounts and Storage Menu.
Select Install.
Click to expand...
Click to collapse
- Navigate to /sdcard and select the CyanogenMod .zip package.
Follow the on-screen notices to install the package.
Optional: Install any additional packages you wish using the same method (if you are installing multiple packages, install CyanogenMod the first and then install any subsequent packages on top of it).
Click to expand...
Click to collapse
- Once installation has finished, return to the main menu and select Reboot, then System. The device will now boot into CyanogenMod. Note that the first boot after installation may take 5 - 10 minutes

I just sold my phone on eBay. So I followed the instructions at: http://forum.xda-developers.com/showthread.php?t=2006946 to Unroot, relock bootloader, & get back to stock firmware.
Everything seems to be working fine expect for the fact I can't get into Stock Recovery or fastboot screen. When I try to get into stock recovery/fastboot screen by pressing the power & Volume up buttons, the phone just starts up as normal instead.
How do I fix this?

Try this:
1) Turn on Developer Features (if you rooted it you know how).
2) download Android SDK (adb and fastboot) again if you rooted you phone I am assuming you know how to use those.
3) type
Code:
adb reboot bootloader
or
Code:
adb reboot recovery
it should reboot into recovery or bootloader if it doesn't. What method did you use for relocking your bootloader ? If you did it manulay via terminal (or cmd) (the laborious/error prone/manual method for re-locking the phone and installing the stock recovery/bootloader/kernel) that might cause this. Try reseting it via LGNPST. you can use the IRC if you need any help : #lg-optimus-g

I've been meaning to update the OP.
I downloaded "Minimal ADB and Fastboot" tool from: http://forum.xda-developers.com/showthread.php?t=2317790, instead of Android SDK.
When I put in the command "adb reboot-bootloader", the phone just starts up as normal instead. When I put in the command "adb reboot recovery", I get the icon of an Android robot laying down with a red triangle having an exclamation mark.
I used the AutoLGNPST instructions to get get back to stock.
I've seen y'all mention to go to IRC channel if folks need help in several threads. But no one ever mentions a link or instructions how to get to the IRC channel.
What should I do next?

did you type adb reboot-bootloader ?
it's suppose to be
Code:
adb reboot bootloader
(with a space between reboot and bootloader)
and the android with a triangle is the stock recovery I think you need the press either the power of the vol button to get a menu like in CWR.
To join the IRC channel you download an IRC Client add Freenode as a server and then type /join #lg-optimus-g
If you don't know how to do any of the above remember Google is your Friend

Vol-down does nothing either.
The phones still boot up into Stock Firmware as normal when putting in the "adb reboot bootloader" command.

You can try downloading the full sdk but at this point and time I am running out of ideas. my suggestion would be re root and unlock bootloader and then try relocking the bootloader again (using the same method) have you asked the guys over at the IRC ?

Hey!
I am having difficulties unlocking the bootloader of my Redmi Note 5. I have already rooted a meizu phone and a lenovo tablet before and had no problems. However, with this one, I am able to enter the bootloader using the following command.
Code:
adb reboot bootloader
However, when I do this:
Code:
fastboot oem unlock
It outputs the following:
Code:
FAILED (remote: 'Token Verify Failed, Reboot the device')
fastboot: error: Command failed
The command
Code:
fastboot oem unlock-go
outputs the same results and rebooting my phone doesn't resolve the issue.
Additionnaly, using the Miui Unlock App doesn't work because it doesn't recognise my phone when in bootloader.
Please help!
Thanks in advance.
PS: I am using a Win10 64bits PC
Edit: I tried an older version of Miui Unlock and it detected my device, but couldn't unlock it. It stopped at 99% and output "couldn't unlock"
IMHO it's always recommended to check for boot-loader can get unlocked
Code:
adb devices
adb shell "getprop ro.oem_unlock_supported"
If returned value is 1, then it's supported otherwise it's not.

You are supposed to use the mi unlock tool. Not these simple fastboot commands (xiaomi wants to make unlocking complicated)
Here is a steb-by-step guide
1. Make a Mi account
2. Apply for an unlock here https://en.miui.com/unlock/
3. Download Mi unlock by clicking on the unlock now and then download Mi Unlock.
4. Download the Mi Unlock app to PC, and sign in with your Mi Account;
5. Shut down your phone manually, and hold Volume down key and Power button to enter Fastboot.
6. Connect your phone to PC using USB cable and click "Unlock".
You will probably have to wait some time (3 days, maybe a week or even a month).
it's been some time since I have unlock my Xiaomi phone so these steps might be wrong. If yes point that out please.

As I said in my post, I have tried using Mi Unlock. I have done all your steps up to the 6th because the app doesn't allow me to click unlock. I am guessing that it doesn't detect my phone in fastboot mode. About the time I have to wait, is it the time between when I apply for an unlock and when I can unlock my phone? This would explain why I can't unlock it. However I saw on another thread that Xiaomi removed the need to apply and wait to be able to unlock a phone. I don't really know how to feel about this one...

Do you have fastboot/adb drivers installed?
Click to expand...

I'm pretty sure I do, because I have already rooted devices before. How do I check?

Seppppx said:
To check your drivers (and install) do this.
1. Plug your phone to the Pc.
2. Boot to fastboot (use googles platform tools, download below)
3. Open CMD as an administrator.
4. Navigate to the folder there you have platform tools in.
5. Type "fastboot devices" if you see no output you either have the wrong drivers installed or not installed
(Download the Google USB driver linked down)
6. To install drivers you open your Device Manager in windows.
7. Look for something like "Android Device" there. If it also has a warning sign that means that there are no drivers.
8. Right click on "Android Device"
9. Click on "Update driver"
10. Click on "Browse my computer for driver software"
11. Click on "Let me pick from a list of available drivers on my computer"
12. Click on "Have Disk..."
12. Browser for a driver under "Copy manufacturer's files from:"
13. Find the driver folder in the folder you saved it to and open it.
14. Double click on "android_winusb.inf
15. Click on "OK"
16. Click on "Next"
Done, you have installed a driver.
Download the Google fastboot/adb here https://developer.android.com/studio/releases/platform-tools

Well, I tried and went up to step 5 and there was no output. So I continued the steps, on step 7 I saw that my Adroid Device Driver had no warning sign, meaning that I have the wrong drivers. I continued on with your steps. After step 11, the control pannel shows 2 drivers named as "Android Bootloader Interface", however before step 15, the control pannel shows 3 different drivers named as "Android ADB Interface", "Android Bootloader Interface" and "Android Composite ADB Interface". The second one is selected by default, so I click ok and it installs. However, the "adb devices" and "fastboot devices" commands still show nothing in the command prompt. Is there something I am doing wrong?

Do you get an output to "fastboot devices" that's the thing that matters when unlocking. I managed to my redmi note 4 to unlock without adb.
You also can get adb in the classic system where you boot. That works for me.

No, "fastboot devices" has no output on my computer, but it has one on another computer for some reason. On mine it doesn't and I need it to on mine.

Okay guys I figured it out. I was missing a step. I indeed had to use the Mi Unlock tool, but before doing so I had to enable an option beneath the "OEM unlock option", I don't remember how it was called but everything's fine now!
I have searched everywhere and have found nothing does a anyone know of a root method for the T-Mobile REVVL 4 model number 5062z

Because phone is based on Mediatek MT6761 Helio A22 chipset you can use either MTK Easy SU or MTK-SU tool

wrong, its a qualcomm
So can this device be rooted or not? Correct replies only would be great.
I am actively working towards it. The phone is def TCL....a lot of the package-names give that away. I installed a new Linux distro yesterday in hopes of getting to the bootloader. There might be an added advantage to loading a DSU in Developer Opyions...will update ASAP.

I can't get the DSU loader to work on mine. It downlaods and says it's ready so I tap on the PROCEED button or whatever and it just reboots back to my Android 11 Stock over and over.

I know little about Android development but I have the device it's not my daily driver so I can test stuff on it and if it goes south it's no big deal. Btw the revvl 4+ is the Qualcomm model, the 4 is the mediatek soc.

Have you had any luck on this yet???
I selected the first DSu , let it install and now the bootloader is corrupt. ( which im pretty sure means its inoperable) so the verity is definitly disabled. I can load into fastboot and baout to test the fastboot oem unlock.

I was bale to let it install. You gotta downgrade to the first firmware it came with and let the DSU install. My dm-verity is corrupted which is, Im pretty sure disabled, and im able to boot into fastboot
Official Bootloader Unlock for T-Mobile REVVL 4G (TMRVL4G)
Unlock DeVops by selecting build number 5 or 6 times. get usb debugging and fastboot oem unlock. if it is not there go to about phone and select the first DSU. itll reboot and say your dm-verity is corrupted. Was then able to boot fastboot by adb reboot fastboot getting the Android with an exclamation coming out of his chest, held power vol + then pressing vol - fastbootd prompted. once your in fastbootd select reboot recovery and then youll get a recovery, fastboot and reboot selection. select fastboot and then you will be able to fastboot devices. once you get an indication your device is there then I used tiny adb with the command: fastboot flashing unlock_critical. An, are you sure? prompt in adb and press y then enter. it'll unlock the bootloader. and boot Orange_state and tell you your device is unlocked.
Anyone found a stock firmware for this yet?

I tried this with no luck.
OEM unlock and usb debugging is on.
adb reboot fastboot
This brings me to fastbootd which seems to be the only place for running fastboot commands. I tried going to recovery but theres no option to go to fastboot. I think mine is running anewer version.
fastboot oem unlock gives this error:
FAILED (remote: Command not supported in default implementation)
fastboot flashing unlock and unlock_critical gives this error:
FAILED (remote: Unrecognized command flashing unlock_critical)
Any thoughts or ideas?

hmm this justs boots the phone back into the android os
then select reboot to bootloader when in fastbootd
or you can hold the volume up while plugging into your computer until you get fastboot mode at the bottom of the screen, you gotta select the dsu at least once to be able to enable orange state on tmobile boot screen
let it sit there forlike 20 minutes itll say android annd ot boot for a long time.... i let it sit there for about 15-20 minutes
im trying to figure out how to make a twrp for this device ow that the bootloader is unlocked
