[Help] ZTE Avid 557 (7.1.1) Root? - Android Q&A, Help & Troubleshooting

Hi everyone,
I've searched a lot, but haven't found anything. I'm afraid my phone can't be rooted by Magisk because the bootloader is locked. Hopefully someone will tell me I'm wrong?
I followed a fastboot guide (enable OEM unlock, USB debug) and was attempting the command prompts via ADB fastboot folder.
"adb devices" shows me my device ID, however the next step - "adb reboot bootloader" - just reboots. And the following step ("fastboot devices") yields nothing.
From what I can tell, my phone has a locked bootloader and there's no way to unlock it. This is why the ADB fastboot command doesn't work for me.
Furthermore, there's no way to install Magisk without this function. I read something about downloading the original firmware for my phone, but I haven't found the firmware anywhere online.
Appreciate any help you guys can offer. Thank you!
Eric

Bump - please anyone / any ideas?

[Q] Asus TF103C Bootloader Unlock

I recently purchased 2 Asus TF103C stocked with Android 4.4.2 and running on an Intel processor. I'd like to load a custom OS/ ROM to them for work however I have not had any success finding a process that allows me to do so. I have managed to root the tablet successfully but that is the extent of my accomplishment to date. I understand that this is a fairly new device and not much has been uncovered yet to achieve this task. Asus is also hesistant to release an unlocked bootlooder update. If anyone is aware of a process whether through adb or the likes please raise your voice to help the community out on this one.

Before following steps bellow mentioned don't forget to install USB and ADB drivers
Also download minimal ADB and Fastboot tools ( for links use google search its easily available)
Configure your compute for fastboot Enable USB debugging on the device.
Connect the device to the computer through USB.
From a terminal on a computer, type the following to boot the device into fastboot mode
$*adb*reboot bootloader
Once the device is in fastboot mode, verify your PC sees the device by typing*
fastboot devices
If you don't see your device serial number, and instead see "<waiting for device>",
fastboot is not configured properly on your machine.
If you see "no permissionsfastboot", try running
fastboot as root.
From the same terminal, type the following command to get info of the bootloader:
fastboot oem-info
To unlock type
fastboot oem unlock
And press enter
May this will unlock your boot loader in general

Hello, I tried your command suggestions to unlock the bootloader and they failed. The command 'fastboot oem-info' does not return anything and 'fastboot oem unlock' returns RESULT: FAIL (unkown OEM command) on the tablet and in the cmd window. Thanks for the suggested attempt nonetheless.
Still having this problem
fastboot oem unlock fails on the TF103C and it says RESULT:FAIL(unknown OEM command). It would be great if Asus could release a tf103c_unlock.apk utility like they have for other Asus tablets (for instance the TF701T has tf701_unlock.apk which works).
Asus, please help!

Can't unlock bootloader (iOcean X8 Mini)

Hello,
A friend of my asked me to install a new version on his iOcean X8 Mini.
After a few minutes into the process, I discovered that I couldn't modify anything at all.
Problems start occuring when I enter Fastboot via ADB (I power up the phone, connect it to PC, give it permission to use Android USB Debugging, then via 'adb rebeoot fastboot' I enter the Fastboot menu). Every command I enter here returns 3 dots just doing nothing. My command prompt is unusable after entering a command (for example 'fastboot oem unlock').
I've tried to push a ROM via ADB but this isn't working as well since it returns something like 'no permission' when trying to install, but I figured this was due to the locked bootloader.
Searched all over the internet for solutions, but so far nothing has really worked. What I somehow did mange to do is root the device (don't know if it was by default, I assume not), via RootGenius.
Anybody got any experience with this, and perhaps know some steps I can undertake to indeed unlock the bootloader of this phone?
Thanks in advance!

Galaxy S4: ADB recognizes device when normal. Although not recognized in bootloader

Hello everyone!
I am currently having issues with my Galaxy S4. I am attempting to install twrp onto it although I am having issues. I have not made any modifications to it, it is running the stock rom and it is not rooted.
I am following this guide: https://www.xda-developers.com/how-to-install-twrp/
I installed adb and fastboot using: https://forum.xda-developers.com/showthread.php?p=48915118#post48915118
I have not gotten any errors.
I type into command prompt:
adb devices
I then get my devices id.
I then type adb reboot bootloader
Once it finishes going into bootloader.
I type adb devices and then get nothing.
I also tried typing fastboot devices and also got nothing.
When I use flashboot flash recovery it gives: <waiting for device>
Could anyone help? I am a newbie at this.
Thank you!

[ZTE K87CA] can't unlock bootloader

I got to the fastboot screen on my ZTE K87CA tablet, but when I try to type the command "fastboot flashing unlock" or "fastboot oem unlock", it just shows "waiting for devices". I have searched quite a bit over the web but I have not found a post where someone actually was able to unlock the bootloader on this device.
This is my first time rooting a device
I am trying to find ways to speed up this tablet and free up ram and stuff and rooting the device seemed to be necessary.
If you have answers to my problem please say so.

Have you enabled OEM unlock in stock rom developer options first with stock rom booted?
Also when device is in bootloader type fastboot devices to see if it is registering your device. If it isn't try getting latest fastboot tools from Android sdk and turning off secure boot if you are on windows 11.

I did all the developer settings like usb debugging and and oem unlock.
When the tablet was on normally running, I did "adb devices" and it showed my tablet, but when it was in fastboot mode I did "fastbook devices" and it didn't show anything.
I think I might have thought of something though. When I downloaded the the usb drivers or something; I downloaded the K87CC instead of the K87CA because I couldn't find one for it so that might be the problem
Look into turning off secure boot if using windows 11, and download latest fastboot sdk package
I'm kind of new to this and don't really know where to download all this stuff. could you send me a link?
Not sure if this is the right place to ask this question, but, have you had any chance to find and install any custom rom in ZTE K87CA? My tablet has become extremely slow and I would like to install something lighter.
thanks.

Enabling USB Debugging on phone is required so that your PC is able to identify your device in Fastboot Mode.
The typical Windows shell commands sequence is
Code:
adb devices
adb reboot fastboot
fastboot devices
[/coode]

I do have USB debugging and OEM unlocking enabled, but the Vivo version of fastboot doesn't detect it, while the normal version does. Unfortunately, I can't use the normal version since it doesn't work with Vivo devices.
Try this
Release v1 · AndroPlus-org/fastboot-vivo
Built with Android 11 source
github.com

I have tried it, but it still doesn't recognize my device. I have the drivers installed, so I'm not sure what the problem could be.
Is there any other way to unlock the bootloader of the Vivo y33s?
Okay, I have now tried something else and discovered that Vivo Fastboot actually recognizes the device. However, when I execute the command 'fastboot bbk unlock_vivo' or 'fastboot vivo_bsp unlock_vivo', it displays the following error messages:
'FAILED (remote: Unrecognized command bbk unlock_vivo). finished. total time: 0.001s'
'FAILED (remote: Unrecognized command vivo_bsp unlock_vivo). finished. total time: 0.002s
