ZTE Blade v9 no Fastboot only Ftm - Android Q&A, Help & Troubleshooting

I want to unlock the bootloader on my ZTE Blade v9 but i can only boot normal in recovery mode and in ftm (Factory Test Mode). In Ftm i can use adb but not with root and without fastboot. If i type in adb "adb reboot bootloader" , its just an normal reboot. When i select reboot to bootloader in the recovery mode too. I can go in Edl on my phone too when i press both volume buttons. So is there a way to go in fastboot? Sorry for my bad english i am german.

Fastboot commands basicallly only work if device's bootloader is unlocked. You do this via enabling in Android Settings -> Developer options -> "OEM unlock", restart device, and run commands
Code:
fastboot devices
fastboot flashing unlock
and again restart device.

The thing is I can't boot into fastboot.

The thing is i can't boot into fastboot.

What do you want to express with this? Do you mean you can't boot into device's bootloader mode?
Code:
adb devices
adb reboot fastboot
What error message do you get when doing what?
Please clarify.

I saw that so often there is not physical camera button or home button. Only a normal camera and with Android a navigation bar. and with Volume + i get in recovery mode and with Volume - i get in Ftm.

I cannot speak russian so I use a translator but i don't understand it clearly. Did someone the guide and explain me how to do it.

If I have understood correctly, OP has a problem with Fastboot Mode (Bootloader Mode) and not with Recovery Mode. Wonder why OP should install a CR ( TWRP ) to solve his problem?
@Kiwilikecookies
A CR replaces device's Stock Recovery, what can't be undone. Do you really want this?

I want to unlock the bootloader to install Cr or Twrp with EDL and when i can backup it i do(wich is not importent for me), root my device and install a custom rom because there are no more official updates.

How Fastboot is implemented on a mobile device if at all ( Note: The fastboot mode is available on a lot of devices but not on all the devices out there ) varies from OEM to OEM. It's on you to find out this.

I know that from my old broken phone where i had a bootloop and had to reinstall android but i want to unlock the bootloader and my phone hasn't fastboot. So i have only recovery, ftm and EDL wich i can boot into it. I only want to unlock the bootloader i know then how to flash twrp (with edl).

Hello, i bricked my V9 . Cant communicate via ADB anymore. It shows me DFU5 COM5 under Windows and when i use ZTE Terminal i can change it it to QDLoader 9008 COM6 but still no communication via ADB possible. The only thing that works is Recovery Mode but can't install update.zip (OEM unlock not enabled, Bootloader is unlocked) and Sideload also not working (adb: sideload connection failed: no devices/emulators found). And it's not a USB, Drivers or ADB problem. Another phone works. Qfil can't communicate with COM6 and in COM5 Mode it says "Switch to EDL Fail". What i can do now?

You can check bootloader with dialer (search it).
Of phone has fastboot mode you can check bootloader with fastboot commands (search it too)

I tried a some other steps. Tried using the video on youtube on a tut. When I get to the oem unlock I just get stuck with a msg sayng "waiting for any device" my device is plugged in, from what I know I have updated the samsung drivers (from previous attempt of other methods) the adb bootloader cmd did put my phone into fastboot mode
(White box, blue arrow point down with a straight line under the point)
(Blue screen with Downloading...)
do not turn off target
What am I missing here?
I tried rooting TWRP 3.2.3. with Odin on the phone again and it still failed
Does anyone else have any more insight to a possible solution?

Can't connect to my phone

I tried to much with installing diffent ROMs and now nothing's working anymore.
My poco starts only to fastboot but I can't connect with adb. Any other possibilities?
Drivers are all ok on the PC, because my second poco is normaly recognised.
Thanks for help.
Given unlocked bootloader, If you can only boot to fastboot maybe your recovery was deleted. You probably need to install twrp:
1.get twrp here:
https://forum.xda-developers.com/poco-f1/how-to/recovery-official-twrp-t3883736
2. If fastboot is working then:
https://www.xda-developers.com/how-to-install-twrp/
If you can boot to twrp then flash a custom rom
Note that I'm unsure if above will work, only guessed
Can't flash twrp because in adb mode it shows < waiting for any device >

I am sorry to say that but I guess nothing could be done to fix your tablet. I would be happy to proven wrong and see some solutions in this thread.
@XX_MRBEAN_XX
The mostly overlooked command
Code:
adb sideload <ROM / MOD>
may help: Get device's Stock ROM and flash it this way.

When I do recovery --> apply update from adb it's say "E: failed to open driver control: Permission denied"

1. Looks to me that the ADB-driver you use isn't suitable: Download and install the correct driver for your Lenovo. tab:
https://devsjournal.com/download-lenovo-usb-drivers-adb.html
2. Wondering why then you didn't flash this Stock ROM by means of Fastboot ?
Code:
fastboot devices
fastboot erase boot
fastboot erase system
fastboot erase cache
fastboot erase userdata
fastboot flashall <STOCK-ROM-IMG>
fastboot reboot

Oh man
become familiar with Fastboot-driver and its subcommands available!!!
Anyway, unlock tab's boot-loader by means of Fastboot before you carry out the commands previously shown
Code:
fastboot devices
fastboot OEM unlock
FYI: I no longer participate with this thread.

To rescue a bricked Lenovo device, download their LMSA tool to a Windows PC. Use the Rescue option.
Have a look on the TWRP thread for the unlock commands. They will only work if you had already enabled Developer Options and OEM unlocking before the device bricked.

thank you for your help my bootloader wasn't unlock it is now thanks a lot
It appears your device's bootloader is locked. Try:
fastboot oem unlock
fastboot flashing unlock
If that doesn't help, search for a guide on how to unlock bootloader for your specific brand.
It also looks like don't really know what you are doing. Make sure you are following trusted guide. If no, I'll be happy to help.

well i did installed custom roms few time but i dont know much, i did unlock bootloader now the problem is i do install custom recovery twrp and it do installed and rom manager shows that custom recovery is installed but pressing volume down + power button just shows fastboot logo and it restart my phone, and with command "
adb reboot bootloader" i am able to boot into fastboot mood and when i go to recovery from their it open stock recovery instead of twrp
Stolen from my guide:
7. Go into fastboot mode
8. fastboot flash recovery recovery.img
9. fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
10. fastboot reboot recovery
12. Sometimes recovery doesn't want to stick as a permanent one. To test it, hold the power button and select "Reboot to recovery". If you reboot to TWRP, you can move on, but if you reboot to stock one, flash recovery using fastboot again and from recovery flash recovery again (sounds crazy, right?). I won't give you instructions on this, research it yourself. Make sure guide you will find is for your device and your recovery.

Fastboot/Bootloader mode inaccessible to root ZTE Blade a5

Hello i wanted to ask about this since i dont see any other thread related to my issue, im trying to install magisk root and im at the stage of accessing fastboot/bootloader, when i go to recovery mode and select "reboot to bootloader" it just restarts the phone, i have tried adb commands didnt work either, same result, just restarts. The "unlock oem" option under developer options is enabled, i could flash another firmware of the same phone with SPD upgrade tool and its still not letting me get into bootloader, (to do this i must press down vol down and connect the usb while the program is on, and it is detected, otherwise it just restarts adb and fastboot tools will not detect it as download mode) any idea or suggestions on how I could root the phone, been thinking about twrp but not sure it would let me install that, looked into many pages about rooting this device and none show anything related maybe its not possible, i saw there are phones with blocked bootloader. the phone is android 9
Have you tried to
- flash the boot.img from the stockfirmware;
- install a recovery (twrp, orangefox, etc.) and rebooted to fastboot from recovery?

TWRP and orangefox dont support my phone, there may be something unnoficial for twrp as i search and im not sure i can flash the phone with a specific boot file since to flash i use a single .pac file that contains the rom ill look into this
For now im not able to flash the phone with custom boot.img or recovery.img maybe i need to pack specific files i dont know about i give up for today
Sorry to hear that...
Have you tried the following command?
Apache config:
adb reboot bootloader
