Hi,
did you install the correct LG drivers?
I don't know if that's important but here is, what I did and tried yesterday evening again on a new laptop (Windows 10):
1. Installation of the V10 Windows driver pack.
2. enable USB debugging in the developer options of the V10.
3. also enable "OEM unlock" in the developer options.
4. close settings and connect phone via USB directly to the computer, do not use an USB hub.
5. open command box in Windows (windows key + R, cmd)
6. change to directory containing Android SDK tools (adb, fastboot etc.)
7. enter "adb reboot bootloader"
My V10 boots into bootloader/fastboot mode every time.

I'm having the exact same problem, except I'm on the latest version of Lollipop. Did you ever get into the bootloader?

which model do you own? As far as I know there are currently only to V10 models which are able to boot into bootloader. First is the American T-Mobile V10 and the other one is the European H960A. For the latter you need to be on Marschmallow to be able to boot into bootloader.

Yeah; I figured that out. I'm using the AT&T model, which has apparently disabled bootloader access.

I have the tmobile lg v10 h901. I'm trying to unlock the boot loader. I have adb and fastboot files installed and the lg drivers. I have the oem. Unlock and usb debugging checked in the setting. I can open the command prompt and use adb devices and it sees my device. I can use adb reboot bootloader and it will take me to the fastboot bootloader unlock screen. From here the command prompt no longer sees my device. I type fastboot oem Unlock and it says waiting on device... Any one have a idea what's going on. Am I missing something?
Try booting into fastboot manually by turning off the phone and holding vol down while plugging it in,then try it but make sure you fastboot devices first to make sure its even detecting it
No that didn't work. When the phone is on adb devices it sees the phone I type fastboot devices and it does nothing. But when the phone goes to fastboot even volume down then plug the phone In it won't recognize the phone just says <waiting on device>
Yeah I keep uninstalling everything and reinstall everything fast boot threw cmd fastboot with the volume button and always get waiting on device when I get to the "fastboot oem Unlock"
So sad ...
Use nexus toolkit for it all. I did. Works great.

I used Mfastboot and it worked like a champ. Could not get nexus toolkit to see my device.
Yes. It boots temp recovery,flashes recovery and root. Also used it to relock the boot loader for sh*ts and giggles. To get it to see my phone I had to download LG bridge on my computer and run it.
I have tried mfastboot and the nexus toolkit and both stop working when it gets to the fastboot oem Unlock. Waiting on device. I have not installed lg bridge so I will try that later and see if that helps.
If you run Windows, you may be missing the USB driver for fastboot. If possible, use Linux where all the USB drivers are included from the start.
I'm having the same problem as well.

When starting all of this (essentially becoming addicted to learning rooting) I noticed that no one mentioned to make sure to enable the "usb tethering" option on their device!! Once I did that, an entire plethora of additional options opened up. That being said, this option won't necessarily make rooting possible, but I think it may help out in this particular situation.
? I really hope this works for you.
1500 years ago, everybody "knew" that the earth was the center of the universe. 500 years ago, everybody "knew" that the earth was flat. And 15 minutes ago, you "knew" that humans were alone on this planet. Imagine what you'll "know" tomorrow.

I got it working I had to go to device manager on the pc then put the phone in boot loader. Then on device manager the phone changed to Android unknown so I set the drivers to Android adb services and it worked fastboot would see the phone and I got root on the v10

Now can you post a YouTube vid for us who are still having this issue! ?
Hello everyone, I'm using Redmi Note 3 and I have tried rooting it several times.
I have unlocked the bootloader. I have also installed the adb drivers.
When I connect phone in fastboot mode and write 'fastboot devices' in cmd it doesn't return anything. But when I connect when its on, adb devices returns the device code.
Please help.
Same, happens to mine too. Used to work with a previous install of windows, but now, nope.
Had this issue too.
Try going to Device Manager and check to see if Kedacom USB Device shows up. Under which, Android Bootloader Interface should be present. Install minimalist ADB and fastboot and right click Android Bootloader Interface. Click Update Driver Software, browse computer, and then click the option to list driver files already present on your drive. It should pull up a fastboot driver that's an older version than the one you currently have. Install that and fastboot will work again.
Doesn't work
Can you please link the files for download when we're updating the driver software.
OEM unlocking and USB Debugging enabled.
ADB never finds the phone in my windows 10 install no matter what drivers I force it to use. - Tried USB 2 and 3.
Fastboot does find it if I manually start it in fastboot mode, but it can't do anything to it
Fails to write when doing oem unlock
Just sits there if I tell it to write the recovery image.
Phone functions fine, I just want root and a 3rd party rom to be rid of any built in spyware.
Any ideas? any way to root it without flashing then I can just have the twrp app flash it?
Nevermind, found a way around it. This dialpad command made it work
Personmans said:
Hope this will help someone with trouble getting ADB/Fastboot to work. I assume you have a similar environment to me: Windows 10, with working ADB drivers on another device (LG G4 in my case)
Set up LeMax2 in developer mode and enable USB debugging as usual.
Plug in usb and dial *#*#76937#*#* check the box that says "Enable AT Port"
The device should immediately give you the approval message for USB debugging.
Note: This will not stick after a reboot.
Once I had this working, I did an adb reboot recovery, but fastboot still did not work. With the device connected and at the stock recovery screen, I had to open device manager, delete the LeMax device, and allow it to detect again. Finally it appeared in fastboot devices and I was able to flash recovery.

Hello,
I have a Straight Talk ZTE Majesty Pro LTE [Z799VL]. It runs Android 6.0.1. This phone occasionally installs apps and has an annoying app called AppFinder. I have tried to root this phone with KingoRoot and KingRoot. So, I need help figuring out if this thing is even rootable. I would get a more accessible phone, but I'm short on money. I know this is short on information, but I'd be willing to help in any way I can.
Any help would be greatly appreciated.
Boop.
I'm fairly certain this phone was released recently. Maybe it's just too soon.
I have this same phone and am having the same problem finding info on how to root it. Keeping a hopeful eye on this thread
Any news for ZTE Majesty PRO unlock?
My friend just brought it from USA to Europe and he want to use it in normal way
Any news?

The OP is running Android 6 but I have the Straight Talk boxed ZTE Majesty Pro and it runs 7.1.1 out of the box.
There is a thread called Universal Method with a file and instructions but my Android device is the only PC I own so I haven't given it a try. The post has a Windows and a Linux method.

Have you unlocked the bootloader?
I recently upgraded to an Android 7.1.1 ZTE Majesty™ Pro Plus LTE (Z899VL) from TracFone,, and was rather dismayed to find out that it has an unremovable Facebook app (among other rubbish that I don't want/don't use).
I've never rooted a device before, and I know that this thread's a little old, but would anyone be willing to post a very-newbie-friendly step-by-step tutorial/walkthrough for rooting this phone (assuming it's possible)?
I have Developer Options enabled, and I can easily unlock the bootloader if that's required. I just want to get rid of these useless (for me) System Apps.
Oh, also: I don't have Linux, so… if it's possible, perhaps the rooting method could work using a Windows 7 PC?
need fastboot to unlock the bootloader. to the best of my knowledge, which aint much. but i can not find access to any kind of dl mode let alone fastboot.

Well, I finally managed to get my 899VL (it's not a 799VL as I'd thought — sorry) to show up as an ADB device; it accepts commands from the ADB program… except that when I execute "adb reboot bootloader", it just reboots my phone.
The ZTE logo shows, then the TracFone logo, and then Android boots as normal. It's as though I simply used the "Restart" option on my phone itself.
Due to this, I can't use "fastboot" commands, because it doesn't seem to enter Fastboot at all.
I do have both the OEM unlocking and USB debugging options turned ON. My only guess as to what's going wrong is that it's TracFone's fault. (Alas, I have no proof…)
Is there anything else that I can do to try and unlock the bootloader? Or is this phone a lost cause?

Well, I don't know about any other method to unlock boot loader.
BTW, in case of some phones, turning on the "OEM Unlock" button in Developer Options unlocks the bootloader automatically, so maybe, just check whether your bootloader is locked or not.
Both Didn't work

I tried using both the wasy for the first one the device not going to fastboot mode it just restarts for "adb reboot bootloader".
i tried KingoRoot, Dr Fone but it didn't work.
Did you unlock the ZTE Majesty Pro Z799VL with this method???

Hey all i dont know what the deal is but ive got an lg g5 that just will not boot to the bootloader. I've tried factory resetting it and all the methods to get to bootloader just reboots the phone fully. Adb reboot booloader, key combos, nothing seems to work. Any ideas??
First, connect your smartphone with your PC; plug in the USB cord in order to establish the connection.
On your computer access the Android SDK folder.
From there open a command prompt window: press and hold the Shift keyboard key while right clicking on any blank space.
Next, in the cmd window type “adb reboot bootloader” and wait while the bootloader mode is displayed on your smartphone
That's basically what I did and worked first time..make sure the adb and fastboot package is installed and open the command window from that folder

Did all that.. I mean I've flashed custom recoveries and roms to other phones before and never really had a problem i couldn't google..this has me stumped. It simply refuses to even access the bootloader.
If it helps it was a koodo phone and is running the latest official patch from lg on nougat. The only thing i could find online was that sprint supposedly removed all access to the bootloader on theirs, but i cant find any real info on that either. It reboots when i send the adb reboot bootloader but its like fastboot just isn't there..?? It reboots right back to the android home screen. Ive tried all possible key combos as well... Ugh
Which model is it..mines the h850
Ive got the h831
I think I've sort of answered my own question. From browsing the forums it appears the Canadian variant has the bootloader locked down and inaccessible, which would explain a lot..lol.. I really hate when this kind of thing is done to the consumer...ugh. Back to xiaomi i guess lol

Interesting - my xianomi hat an locked bootloader and i had to ask for permission (for the phone I bought!) to unlock the bootloader.
LG is also locked, but the unlocking procedure is way easier.
