Good day!
Im trying to unlock bootloader to root the tab. Generally, i have followed a guide in a thread posted in this site (rooting zenpad c7 z170c) which was claimed to work with z370 by some. There were no problems encountered when using the method except when im already in fastboot, commands i enter like "fastboot oem unlock" return a "failure unknown command " from the prompt. I tried another command "fastboot flashing unlock" but the prompt returned "failure remote failure".
After that, i tried using "fastboot getvar all" and showed that bootloader is secured and still locked. I even tried "fastboot boot [root image name].img" but would cause an error since device is still locked.
I used win7 while doing this and got the adb installer 1.4.3 from a thread here.
All help is greatly appreciated.thanks

... even though my experience (in:http://forum.xda-developers.com/and...-c-7-0-z170c-p01z-root-method-t3311752/page21 ) of not having to lose my data, apps and settings was a BONUS, do BACK UP your data, in case something different turns up for you.
good luck!!!

I want to unlock my phone for installing a ROM and I have setup the Android SDK alongwith all the drivers USB debugging ON, but 'fastboot oem unlock' is resulting in three dots (...) nothing else. Phone keeps displaying the '=>Fastboot mode' text. 'fastboot-windows oem unlock' results as command not recognized. 'adb devices' and 'fastboot devices' both successfully give the serial numbers. 'fastboot oem device-info', 'fastboot flashing get_unlock_ability', 'fastboot flashing unlock' all these also result in three dots (without the text of <waiting for device>).
'flashall' without unlocking failed.
I have also finished trying 3 different data cables with 4 computers. I don't have any linux around me, only Windows 7, 8 and 8.1. Also tried with root and without root (Rooted the phone with Kingo) and tried to run all the commands from the SDK folder as well as administrator.
Please help me with unlocking the oem.
General info: the phone is having Android 4.4.2. Willing to install android 5.1.1.
I have the same problem! Please help

A lot of phones have a code you need to enter along with the fastboot command to unlock. Check manufacturer's website.
Moto phones, several lenovo phones, etc.

Not all phones show that. Some phones just show the device logo splash screen.

If your android rooted using KingRoot then it must your bootloader is unlocked.
Try command in fastboot mode
"fastboot oem device-info" then see bootloader unlocked is true or false. If true means your bootloader is unlocked.
What ever i am typing its saying only "FAILED <remote: unknown command>"
Only the working code is "fastboot devices" 😥

Hey xda plz help me how to unlock bootloader for Lenovo a3300-hv plz help running ROM 4.4.2
Touchscreen unresponsive after "fastboot oem unlock" (Lenovo Tab3 10 Business)
Hi there,
I just got a TAB3 10 Business - Type ZA0X - Model ZA0X0125SE, 32 GB.
I thought it would be nice to root it and be able to boot TWRP, so I first tried to unlock the bootloader.
I booted into fastboot and from the ADB and Fastboot SDK Platform-Tools I ran this command:
- "fastboot oem unlock" : that appeared to be succesfull and ended in "OK"
- then with "fastboot boot twrp.img" (the img file I found here: https://www.androidfilehost.com/?fid=457095661767138880 I booted into TWRP but found out the touch screen did not work
- then I booted into normal mode, the tablet was reset to factory settings and I ended in the setup screen of Android: "Choose language".
But I can not choose a language as the touchscreen is not working.
Can anybody understand how the oem unlock command has resulted in an unresponsive touch screen?
And any idea how I can solve this?
Thanks!
Actually it was not the "fastboot oem unlock" command that caused the issue, but the "fastboot boot twrp.img" after that.
Although my firmware had a different type of version number (TB3-X70F_S000004_161208_ROW_P), I decided to flash the device with the SP Flash Tool and the "TB3-X70F_S000025_160527_ROW" firmware that I found here: https://www.androidfilehost.com/?fid=673368273298936487. Thanks Tzul !!
After flashing this firmware, unlocking the bootloader, flashing TWRP and installing SU (to get root access) went smoothly.
After an OTA update to S000026 (TB3-X70F_S000026_170208_ROW, I had to install TWRP and SU again, but everything seems to work fine now
Apparently my original firmware version did not work well in combination with the TWRP version from Tzul.
Do you have firmware file left? I can't download it, stuck on "Searching for mirrors..."

nvm, tried after some time, it got fixed somehow
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?
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.
