Hi!
I have RN2 with MIUI 16.6.7.0 with root access.
ADB v1.0.32
Win 8.1
If I run "adb devices" when phone is running system, I get response "s/n device" as I should. But when I boot phone to recovery (MI-Recovery 2.0.1) I get "s/n unauthorized".
I have tried rebooting PC and phone, disabling and enabling USB debugging, deleting adbkey and adbkey.pub on PC (only instance was in users/user/.android/), revoking USB debugging authorizations, changing USB ports. Nothing.
The last thing I did:
1. reboot phone to system.
2. developer options > turn developer options on/off > turn debugging on/off <> Revoke USB Debugging Authorization
3. reconnect phone to PC
4. was asked: RSA key fingerprint + always allow from this computer > OK
5. run "adb devices" gives "s/n device"
6. disconnect phone
7. power off phone
8. phone to recovery
9. reconnect phone
10. run "adb devices" gives "s/n unautorized"
11. disconnect phone from USB
12. run "adb kill-server"
13. run "adb start-server"
14. reconnect phone
15. run "adb devices" gives "s/n unautorized"
I guess something is wrong with recovery mode on the device. Any ideas?
Thank you
MK
+ run "adb shell" gives " error: device unauthorized. This adbd's $ADB_VENDOR_KEYS is not set; try 'adb kill-server' if that seems wrong. Otherwise check for a confirmation dialog on your device."

"On the device, vendors public keys are installed at build time in /adb_keys. User-installed keys are stored in /data/misc/adb/adb_keys."
On my device user-installed keys are stored in /data/misc/adb/adb_keys. The only other instance of adb_keys is /bin/adb_keys. If it has any relevance.
You need to check in the device the popup, the device ask if you want authorize your computer for connection with adb, remember you need to enable adb debug first with push 7 times on miui version into about device.
In recovery adb isn't available you can enable only the adb transfer from the advance menu.

Hi!
Thanks a million for your reply. :good:
I did all that already in steps 2, 4 and 5 and it worked. My problem is adb in stock recovery mode.

Damn I have much to learn (hundreds of pages in a few days and I still dont know anything . So stock recovery doesn't come with ADB access and I am trying to do something that can not be done? ClockworkMod recovery for example should have ADB support if I understand correctly?
I also have that proble my device not connected to phone what I do tell me..

If problem is PC <> phone then install drivers for your phone on PC.
Or describe your problem better.

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

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???

Hi everyone.
I apologize if this was already asked.
I own a Symphony H50. I am trying to install windows via change my software but it shows device too slow or protected by manufacturer.
So googled it and found that i need to unlock my boot loader.
So I installed adb,fastboot,drivers including bootloader interface driver. And booted into fastboot mode. And typed "fastboot oem get_unlock_data" and the command prompt shows 3 dots (...) And the cursor keeps flashing. And no confirmation message shows up on my phone.
It only shows "FASTBOOT mode".
Another thing i found out while installing adb drivers that it listed my phone manufacturer as HTC.
So is the problem with my phone?
And how do i fix it?
It may be a problem with driver, uninstall the previous one and install Koush universal adb driver from kaushikdatta.com
Use the link given below for a thorough tutorial to replace drivers.
http://www.makeuseof.com/tag/android-wont-connect-windows-adb-fix-it-three-steps/
Thanks for reply,
I'll try the drivers.
Though my adb drivers are working fine. My issue is with fastboot.
When i boot into fastboot mode it shows "FASTBOOT mode" on a black screen.
But i would try with the
That black screen with fastboot mode written at the bottom comes up on every phone when you boot into bootloader.
Please read the whole guide before proceeding.
You may skip the driver and adb installation part if u have already taken the measures I stated before.
Try this,
Download adb and Koush Universal adb driver and install them on ur pc, always install the driver first and don't install the drivers adb setup asks u to install.
Run command prompt as administrator.
Open the folder in c drive where adb is installed, u can use file explorer for this.
Press Shift+right click and select open command window here.
Enable USB debugging on your phone and connect it to the pc by a USB cord.
Enter command "adb devices" without quotation marks.
If it shows some device connected, only then proceed further.
Enter command " adb reboot bootloader"
Enter command " fastboot devices", if it shows some device to be connected, only then proceed further.
Enter command " fastboot oem unlock".
Ur phone may then ask for final confirmation on the phone screen, select yes.
When procedure completes, type "fastboot reboot" and ur phone will reboot.
U can now use Kingoroot or any other tool for rooting.
Hi, I'm trying to learn to use adb/fastboot and here are a few random things I ran across I'd like to ask to understand better how it works.
Does adb work only when the phone's on and usb debugging also on or do some commands also work in other modes? Example: phone's off (Honor 6) and "adb devices" doesn't recognize it but all "adb reboot" commands work no problem, why?
Could some adb commands be blocked by the manufacturer? On another device (Prestigio), "adb reboot recovery" works but "adb reboot bootloader" doesn't do anything. Is there a way to safely stopping a running command?
Example: in the recovery mode, I accidentally started the adb sideload and the phone prompted me to enter the full path to the sideloaded file (in the PC terminal); trying to enter a non-existing path didn't do anything, the sideload screen on the phone was still there; holding the power button didn't help; removing the battery would probably do the trick but it's not removable so is there a safe way to stop the command? Maybe adb kill-server?
Y cant i get fastboot drivers to read in Windows 10. I have updated the software to the latest update. Developer options are turned on. USB configuration is set to file transfer. In a regular state Windows 10 readds the phone and I can access the contents of the phone. I opened a power shell (regular and as admin) I typed "adb devices" it reads. (I have enabled advanced reboot.) I use the command "adb reboot-bootloader" in boots to fastboot. Now it loses connection. I Open the Run dialog box by pressing Windows Key+R. Type “devmgmt.msc” besides Android is a yellow triangle, then click Update Driver.A new window will pop up. Select the ‘Browse my computer for driver software’ option. I copied the drivers from the OnePlus 5 folder. Try to install but nothing. This is where in stuck. Please help. Thanks
