[Q] Bricked ZTE Maxi plus 5 - flashed wrong firmware, no adb, no fastboot

Hello,
I own ZTE Maxi plus 5 device. It is a Android and Firefox OS device (also known as Unagi). I unwisely flashed geeksphone Firefox OS firmware. Now my phone is bricked, I'm trying to enter fastboot mode (via Volume Up + Powe button) but I only receive "waiting for device" message when running fastboot.exe. When I run adb.exe, device is not listed. I think that USB on device is not working - there is no message about driver installation in Windows, in Linux dmesg doesn't show any devices when connecting USB cable. Is i possible to enter fastboot and flash stock firmware? Recovery mode is also not working (i see only splash screen, same as in fastboot mode).
Thanks, best regards,

Bricked after firmware upgrade?
I have a Vido N101RK 10.1 inch Quad Core RK3188.
I upgraded the firmware with the RKbatchtool.
All went fine and it succeded.
But now, the tablet won't startup anymore. The screen keeps black.
What can I do?

P.S. I can run phone in download mode, but I don't have right mbn files. Seems that the phone model number is "P752TV".

[Q] Questions about Fastboot & Drivers

hello ,
After reading a lot about my device i see a lot of people saying we need fast-boot working for our device to start any type of development , What causes a device not to work with stock SDK fast-boot ?
When it comes to fast-boot, what exact drivers are used to recognize the device in fast-boot mode ? for example the current drivers installed under LG drivers are LG Android Driver , LG SP USB Driver , LG United Mobile Driver , LG USB WML Modem Driver ?
i use both windows and Ubuntu and followed every fast-boot guide on the internet and just cant quit get fast-boot working , i can get adb commands to restart the device but that's about it .
the device im working with is the LG G Stylo LS770 .

Hi !
Does your phone enters in android normally ? If yes , enable adb debugging in developer options , connect it to PC , open adb command window and type
adb reboot bootloader
Good luck !
