Zte Tempo X- N9137 - Android Q&A, Help & Troubleshooting

So I am trying to reboot into fastboot mode/bootloader, and every time I do it it just normally reboots the phone.
Anyone know how to fix?

I have usb debugging enabled and run the following command from shell on the desktop:
adb reboot recovery
Click to expand...
Click to collapse
This requires a PC connected and adb drivers installed
On the ZTE, enabled USB Debugging / Unlock Bootloader
The second is to power off the phone, hold ( - ) volume while powering on the phone. Continue to hold the ( - ) volume until fastboot starts.
If you cannot access fastboot, it's because of the rooting scripts. I currently cannot access fastboot either.

Turn off Phone
Hold Volume Down and connect the USB cable from PC to Android.
Phone should reboot to bootloader
If Volume down doesn't work, try volume up

in the system files the adb file exists but the fastboot file is missing !
Did you check usb debugging in developer options and oem unlock checked?

Volume down did nothing.
Volume up started a firmware update that is stuck at 0%. Had to remove the battery to reboot.

Fastboot mode on Acer A3-A30

Hi!
I recently got my new Acer Tablet A3-A30. After unlocking developer options and activating debugging I was able to use adb. So I rebooted into bootloader to see if fastboot works - it did not! The output of fastboot devices was empty (this and the following commands were typed as root).
So I killed adb with adb kill-server, disconnected it from my computer and turned it off. After a few moments I turned it on by pressing power while holding Vol[-]-Key. Again the tablet booted into fastboot mode. Now I connected it with my computer and hoped fastboot will recognize the device now. Again, the output was empty.
I noticed, that after connecting the tablet, the text fastboot mode on the display didn't change - all other devices I put into fastboot mode showed fastboot usb mode or similar after I connected them with my computer.
I tried different USB ports - nothing changed.
I'm just wondering, since I'm not familiar with acer devices: Is there a hidden key sequence to get into fastboot usb mode?
Thanks,
Tintom1

I have an a1-830 and it can be a real pain in the ass to get anything working on them. Try this, since you got adb working, adb reboot bootloader, then wait till it says fastboot cmd waiting or something. If that din't work, reply!

If you are using Linux, try running fastboot with the sudo command. Also, the drivers might not be properly installed, check out this to download them.

Your computer is unable to detect the phone in fastboot mode. Uninstall and reinstall the fastboot drivers, the proper ones. If successfully detected it should not be rebooting.

" fastboot devices "​If a device with device number shows up fastboot drivers are installed correctly or else if nothing shows up fastboot drivers are not installed properly..so check them.

Im having this issue now on my redmi note 4x.
Do you have a solution? Thanks
Man, you need adb bootloader interface installed properly.
Open device manager, and you'll see something popping out when you connect your device to pc on fastboot mode, there you can see what's wrong. So all you need is update that wrong driver (the one that popped out once you connect your device in fastboot mode) and install redmi note 4x driver, just ignore your disappearing fastboot mode in your device, keep install it. You should have your redmi note 4x driver prepared btw, you can google it.
Good luck!
use USB2 port, do not use USB3

That is because your computer does not make any connection with your phone. Are you sure that you have all drivers installed. You can install fastboot drivers with mi flash tool but before that write this command in an admin cmd - bcdedit /set TESTSIGNING OFF and reboot. Now you can now install the fastboot driver from mi flash tool and try your luck

So drivers are needed for fastboot flashing a xiaomi phone?
Why I didn't need drivers to use fastboot with other phone manufacturers?
In these phones (oppo, op) the phone stays in fastboot mode until you exit or shut it down.
I think xiaomi did a bad move with this.
───────
EDIT: It works in debian without any additional drivers.
Fastboot recognizes the xiaomi phone with "fastboot devices" command.
So it was as you said.

Fastboot commands not recognized after installing RR rom

So I want access the TWRP through fastboot command( since volume up + power botton wont work) but it's not reconizing the device.
I have USB debug on and I don't know if i have OEM unlock mode on because I can't find it in the developer tab.
I only want to root the device so I can install the google cam.
Any suggestions ?

RR should also have advanced reboot in developer options. You can than simply reboot into recovery.

Thanks for the reply.
The problem is that I have no way of reaching TWRP , If I do the Power+ volume up I will go to the MI-recovery 3.0.
What I do is, I restart the phone and only hold down the volume up button after the screen goes black. That always gets me into TWRP. But I usually use the advanced power menu because that's way easier.
Fixed the fastboot not get recognized on my computer.
I had to disable driver signature verification. Then I installed the proper TWRP version. Now the Volume up + power goes strait to the TWRP.
I am just posting here someone might find useful.
ty all for the help.

Did you forget to boot into your recovery.img after flashing TWRP via fastboot? "fastboot boot recovery.img". A lot of guides stupidly leave that out.

No my problem was that I could not even call fastboot through console because my computer wont recognize the device. If i called "fastboot devices" on the console it would not show any answer. Disabling driver signature verification made my computer recognize the smartphone usb , so all the fastboot commands worked as intended again .
You have driver problems, donwload the latest adb or install a virtual machine with Ubuntu or Debian, after that install android-tools-adb and android-tools-fastboot. Then connect your phone to the virtual machine and access adb from there.

Question Fastboot?

Hello.
Today I updated from the Nord 5G to the Nord 2 5G.
DN2103_11_A.14
I have enabled developer mode, oem unlock and adb debug.
I can't access fastboot properly. And recovery is different from the previous Nord. There is no option to reboot to fastboot.
I use adb reboot-fastboot and I enter a sort of fastboot. It says:
fastboot_unlock_verify ok
The device is in fastboot mode which is only for debug Android devices. if you want to exit fastboot mode, please long press volume up nad power buttons simultaneously.
Phone is recognized in windows when in adb-mode (normal booted), but does not recognize it when in this new fastboot mode. Just an Android with an exclamation mark on.
Halp?

Don't own this device but try: "adb reboot bootloader" instead and test fastboot commands from there (don't navigate to Fasboot from bootloader).

This is normal behaviour with the OPN2 afaik. Your PC can access the USERDATA folder whilst in ADB mode (aka booted normally) and whilst in the recovery bios. Your pc CANNOT access the USERDATA folder when your phone is in fastboot, or at least I've never been able to on my Nord 2.
Your op didn't include what exactly you need help with. Everything you described is exactly intended behaviour. From my understanding your seem to have booted into fastboot mode, then noticed your PC can't access userdata. That's normal, you can still use fastboot commands and your PC is still connected to the phone. Your "My Computer" folder on PC not showing the phone shouldn't be any cause for alarm.
Now I'm starting to guess, because you might have failed to mention; Are you unable to send fastboot commands to your phone when its in fastboot mode?
Are you trying to flash a file?
What's the issue?

I am unable to send fastboot commands. Is not recognized by "fastboot devices". And this fastboot mode looks nothing like my previous phones. 2, X, 5T and Nord 5G. <waiting for device>
I want to do my "usual routine" with my new phones. Unlock, flash twrp or other recovery, and flash magisk for root.
After a "full wipe" of ADB and fastboot drivers, I reinstalled and got it working!
nothing. only recovery mode
vol down+ power =recovery mode
vol up + power = normal boot
I finaly boot into fastboot mode with adb command only (adb reboot bootloader)
With buttons wont work.
But i can't enable Volte/Vowifi (thats why i wanted to boot there).
Can you send adb commands when in recovery mode ?
I'm trying to enable VoLTE too, but adb only detect phone when powered normaly, not when in recovery mode.
i don't know about adb but in fastboot you can.
I can't enable volte/vowifi in fastboot with this commands.

Could you go into more detail on what you did in the entire process exactly? Did you use the drivers and adb install from the 15 sec installer? Did you simply uninstall them in the Windows Device Manager and click on "update drivers" to find the local drivers from the 15 sec installer? Which ones did you choose? Sorry, these might be dumb questions, but I'm admittedly very stupid when it comes to Windows and drivers in particular.
I did the exact thing I described above but I'm still just getting that message. Additionally, "fastboot devices" won't list anything and "fastboot oem unlock" will wait for the device for eternaty. "adb devices" on the other hand will list my device while not in Fastboot.
