[ZTE K87CA] can't unlock bootloader - Android Q&A, Help & Troubleshooting

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.

Problems unlocking, not finding device..

Hi good people of the internet,
I recently brough a brand new ZTE Blade Vec 4G and i wanted to replace the Android OS that came with the device before i start using it, but i hit a snag when trying to run the shell commands via USB.
I have been trying via my Ubuntu machine, but i also tried allitle in Windows, but i got the same result there.
So far ive been following this list (could not post the links, but its via the main "Installing Ubuntu for Devices" page:
Unlock the Android device
To install Ubuntu, you must first “unlock” the Android device bootloader.
Warning: Unlocking deletes all data from the device, including apps and other data. You may want to create a backup first.
You must first have enabled USB Debugging in the Android OS.
Boot the device into the Android bootloader:
$ adb reboot bootloader
Tip: When the device is booted into the bootloader the screen displays the green Android robot lying on its back with its front panel open and a highlighted Start menu item.
Verify the device is connected to your Ubuntu Desktop as follows:
$ fastboot devices
025d138e2f521413 fastboot
Unlock the device as follows:
$ sudo fastboot oem unlock
Accept the terms of unlocking displayed on the Android device.
Reboot the device to Android as follows:
$ fastboot reboot
Complete the first use Android setup steps, entering minimal information: Android and its data is about to be deleted during the Ubuntu install.

Ive only made it to highlighted point, but when i hit "sudo fastboot oem unlock" it just stops on < waiting for device >, and when i try to find the device i cant see it when in "Android system recovery mode".
Any help would be great as ive spent near 5 hours trying to do this now
I don't think it's possible to unlock the bootloader on your device yet. From what I've read, even the adb reboot bootloader method does not actually get you into fastboot mode. Replacing the OS with Ubuntu will not be an option because of this as well as other reasons.

Thank you for the reply. So how can i remove Android at all then? would it be better to try something like CyanogenMod or MIUI? I have also been looking at Firefox OS, but if i cant remove Android, then i cant really do much at all..
Just saw this thread:
http://forum.xda-developers.com/general/help/soshphone-4g-zte-blade-vec-root-t2810210/page1
Guess i just need to make do with the unrooted Android for now..
Pretty much stuck for awhile. There might never be an option for it. Many phones never get the chance to have different OSes or even custom versions of Android. Hopefully that's not the case, but it's not uncommon.

[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!

Rooting/unlock bootloader: I've tried them all

Ok, this is getting very frustrating. I've been rooting phones since the day the G1 came out, and having gotten a v10 yesterday and tried to root it, all of a sudden I have become stupid. I have tried every type of method om this board to attempt unlocking the bootloader, rooting, and installing TWRP. I've even tried the Nexus Root Toolkit and the I-Root/V-Root methods, both on the phone and from the PC. Even though I "sometimes" am able to type "adb devices" and actually get the device #, many times, both when trying to get into bootloader mode or as with both KlicKit and NRT, it more often than not hangs at "waiting for device". Is there anybody that has had a similar type of difficulty that has figured out how to make this happen? I took it out of the box and started to do my thing, so I am assuming it has a locked bootloader? This should not be so difficult to accomplish. Any insights would be appreciated.

If you have a T-Mobile device you are able to root etc. Make sure you have usb debugging enabled, and tick enable oem unlock in developer options. I presume you have a driver issue. Just go ahead and reinstall the drivers and try again.

Hi Mark. Which drivers? I have literally tried to use 5 or 6 different ways of installing drivers: device manager/Nexus Root Toolkit/the full Android SDK/KlicKit/adb setup 1.4.3 and maybe two others. Do you know a source that I am missing? Why would my phone out of all of the thousands sold NOT have proper drivers installed? This makes no sense. Weird thing is I can get to the bootloader screen using the adb reboot bootloader command.

Can I ask what commands your running when you're rebooted into boot loader/fastboot?
I'd say to try the LG drivers first and if not go with the Samsung ones. They're relatively universal.
Im also having problems. Ive installed every driver from samsung lg google and universal drivers and still nothing. I can get adb to reconize the device and reboot my device. I type in fastboot oem unlock and it stays on waiting on device

Sure. Usually I am able to get into the bootloader(if adb devices recognized what's going on) where I get the LG logo and the words on the top left say "Welcome to Fastboot Mode". I put in adb reboot bootloader, which does get me there. Then, I put in fastboot oem unlock and that's when it hangs on waiting for device.

Exactly. I guess the "misery loves company" thing is operative here. If you do figure it out, PM me, I will do the same.
what does it say when you type "fastboot devices"?
I am 100% certain you have either a driver issue which you should look into in your device/driver manager on your pc. there's likely something broken (common problem). Or you do not have usb debugging/enable oem unlock checked. I'm leaning towards a driver issue. It is also possible that if what you say is true and have installed too many drivers that something is conflicting.

Progress!!! I was able to use Tech Know to unlock the bootloader. Now, if I can get the phone to behave enough to install twrp and root I will be good. But, KlicKit is not doing it, still hanging. And, when I type fastboot devices it just opens up another prompt and sits.
Edit: And, I am able to use fastboot reboot to reboot from the bootloader, but I get an error message when I try KlicKit, but it goes away too quickly to read what it says. OK, so now that I have an unlocked bootloader, do you have a recommendation of what method to use to install twrp and to root. (I have renamed the twrp file to "twrp.img" and I have both SU 2.46 and 2.52 on my external sd).

Just follow the instructions in the "how to root..." thread. it goes step by step and I believe there is a video tutorial as well. You'll need to do a quick search for this.

I literally figured this out 2 hours ago. It is a Driver issue but reinstalling a .exe will not work. This is what you have to do!(did this on Windows 7)
Boot up fastboot and plug into your pc.
Go into "device manager"
While in fastBoot your phone should be listed in "other devices" simply titled "Android".
You have to re select the Driver your self , do not choose for it to automatically search.
Look under the "Android devices" tab and if you have the LG drivers you should see something like "LG adb interface blah blah"
Choose that driver and fastBoot should work.
Try "fastBoot devices" in cmd it should finally recognize.
I've also heard success from selecting any "adb interface" driver
I think I'm gonna make my own thread and YouTube video to break this down further. I've also been and adroid user since the g1 and. I hate being asked "are you sure u ticked usb debugging?"

Hi Duece, thanks for that. I am ok up to where I actually try to root, meaning, I am fine with getting into the bootloader. When I type "fastboot devices" it does give me the model # and the word fastboot next to it. The bootloader is now definitely unlocked. It's the next steps (twrp/root) that I get stuck. When I use KlicKit, it does do something for a second and then it just closes. Have you successfully installed twrp and rooted? That's where I'm jammed up. Thanks...
Edit: although I have the twrp.img file on my ext sd, and I renamed it "twrp.img" and typed that command in when in the bootloader, but it says "error: cannot open twrp.img".

put the twrp.img in the same folder with fastboot, flash recovery by using
Code:
fastboot flash recovery twrp.img
After twrp flash ,shutdown/ restart to factory rest mode and go for 2x "yes". if entering TWRP fine, then flash a supersu 4.52 zip from sd
I am using 2.8.x twrp working fine

Aah, that would make sense. However, I did a search in Root Explorer and nothing came back with "fastboot". Do you know where the most likely place would be?

fastboot is a platform tool from google. You should have it downloaded to computer(Win) and use it with CMD(command prompt)

No good. typed adb reboot bootloader, it went right there. Then typed fastboot flash recovery twrp-2.8.7.1-h901.img, it gives an error message: cannot flash twrp-2.8.7.1-h901.img. Typed fastboot reboot, went right back. The video's great, but if the commands don't take, it 's moot. If anybody figured this out (same issue), please let me know how. This is taking forever.

Positive. The code I am putting in is twrp-2.8.7.1-h901.img. That's what most things I've read say to do. The other thing I have been thinking about is that KlicKit is supposed to have everything pre-loaded, and even it won't do it. KlicKit gets me into fastboot, then something really quick happens and the command prompt screen closes. What driver system do you use? I've installed a number of them, then deleted them as well, just to try to make sure there are no conflicts. However, I now have two devices in device manager: "android device.lge mobile adb interface" and "portable devices/v10. Does one need to go, maybe?
Power off your phone , hold volumn down and connect usb to PC.
Do you see "LOCK STATE - UNLOCKED" ?
if yes, type "fastboot.exe flash recovery twrp-2.8.7.1-h901.img "

driver trouble

I bricked my opx I was able to bring it to life but the ****ty recovery doesn't let me flash anything so I am stuck no OS and boot loader locked and my computer isn't recognizing the dam thing I have installed SDK tools and google USB drivers but for some reason I am not able to get the Dan thing to connect right when I try via adb sideload it starts then the phone says fail...... Please help I am love this device and brand but I am getting really mad I am about a week in to trying to fix this but no luck I am using windows 10 also
Sorry to say, but you gotta follow this thread.
[GUIDE] Mega Unbrick Guide for A Hard Bricked OnePlus X
Since you may ignore the other thread you started or it may get deleted I'll copypasta here:
We can try to unlock the bootloader as it is now, but that doesn't usually work unless you checked "OEM Bootloader Unlock" in the system settings before the device was bricked. Hindsight is 20/20 but as a word of advice for the future, never ever mess with a device unless you know the bootloader is unlocked or have made it possible to unlock it later without the OS. It also doesn't void the warranty on OnePlus devices to do so.
So first things first, the recovery will normally only flash the stock ROM as provided by OnePlus. You can download that file from here: http://downloads.oneplus.net/2016-04...xygenOS_2.2.1/. For future reference, when the bootloader on a device is locked the bootloader will not boot any software that isn't complete stock. If you try and change the OS or Recovery and it's not stock, the bootloader will not load it. This goes for any Android device.
If ADB sideload is working for you but hasn't been installing on the device (as-in, it sends the file but the device fails to install it) then you should be able to just sideload the zip file. It'll be slow though since it's about 780megs. If it doesn't send it then you can try using the ADB "push" command which is like copy and paste. You "push" the file from your computer to a folder on the device (you can see what folders are available using "adb shell" and then navigating with CD "change directory" and LS "list". If you can't find the sdcard you may have to mount it). Once again, it'll push slowly but once it does you should be able to install it from the internal memory.
If that works and it boots, go to Settings -> About Phone and tap the Build Number until it says you've enabled developer settings. Go to Settings -> Development and turn on "OEM Unlocking". Power the phone down. Hold the Power key and Volume Down until it shows the OnePlus logo and "Fastboot". I believe if you have the Android SDK you have the Fastboot program (it's commandline like ADB). Open CMD or Powershell and as long as it's the only device plugged into the computer you should be able to simply type "Fastboot oem unlock" and it will unlock the bootloader. Once again, it doesn't void your warranty.

Rooting Insignia tablet NSP10A7100 with android 6.0.1 marshmallow

Iv'e been looking around for a root for my device and I can't seem to find a root. Is there even a root for it yet?
Guys come on. Its been almost 4 months now and still no root. I just want to delete all the bloat ware off my device so that I can use it more.
Well I guess there isn't a root for my device. If anyone needs to root this device your out of luck.
Perfectly fine Android build per se; you want to change what?
You were joking, right? Going into the about/device and tapping on the kernel version lets you pick a ROM from microSD.
One supposes that you would use adb to make verify all your build assumptions are OK, grab Android developer kit and blobs on your development box of choice, and build your new improved ROM. Boot to glamour-shot portfolio FTW.
Separately, Internet reports are that Kingroot.net works, at least from the Windows side (perhaps after a little name tweaking from that side of adb resource names; see the perfectly serviceable P10A7100 note on Reddit. On the Android side I'm still looking at a spinner and '01%' root acquisition progress. But then I should give Kaspersky and Malwarebytes the day off while this is going on, right?
Hello,
New to the adb thing. I want to say first off, that this tablet has to be the worst POS I have even had. Its has 32 gb of memory but I can only use 6 of it for apps before it slows to a complete useless doorstop. Could anyone reccomend a good rom image?
I have the same issues. Can't believe they would sell such a POS! That's Best Buy a crap store that used to be one of the best.
Insignia NSP10A7100 rooting
Any luck finding more info on root for this device? I've only tried kingroot so far from the apk but no luck. Also trying to find more info on how to root manually (without a script) or how to write my own script? I've enabled developer options, enabled bootloader unlocking. I can run adb from my ubuntu box but adb reboot bootloader just reboots? I see the option when tapping kernal to update a .zip file but what file? I haven't seen any roms or recovery's for this device. Any help is appreciated!
Insignia NSP10A7100
I was playing around with adb and fastboot tonight and did learn a few things. I had to use "sudo fastboot flashing unlock" to get the bootloader unlocked. Whatever that switch is in developer options to unlock did not seem to unlock anything. I did a getvar all and the output showed it as locked. sudo fastboot with no options gave me the list of commands to use. After reboot there was a screen that warned about the bootloader being unlocked and that it was not safe. I thought it was going to be stuck there but it did finally reboot into a fresh system. I've got files with the output of getvar all and bugreport if any of that info would help anyone with the rooting. If anyone can point me to more research I'll continue to play with this.

I just got one and trying to access fastboot. I have model p10a7100. When I pick fastboot from recovery mode, I momentarily get resting android with "no command" and get recovery mode again. Because of low ram, I would like root access to install magisk for modules. Please explain your unlock method.

I have had no success trying to get root access. I only got the bootloader unlocked. I used adb to reboot into fastboot mode.

Teach us your adb method. I have tried everything and it won't enter fastboot mode. If I type adb reboot fastboot, it just bypasses fastboot and boots up the tablet to android.
Update: I entered the adb command adb reboot fastboot and I get a giant green screen with a walking android robot in the center. Then I lose contact with the tablet. Never saw that before.

That is what I did also although I used "sudo adb reboot fastboot". Still not sure if the sudo is required? The giant green screen means you are in fastboot mode now. Type "fastboot" at the terminal to see a list of commands. The one I used to unlock was "sudo fastboot flashing unlock_critical". Type "sudo fastboot flashing get_unlock_ability" to find out if you are able to unlock the bootloader. This is as far as I got. Apparently I could now flash an image if I could find one that would be compatible. If you get any further or find one let me know.

Are you on Windows? I'm on Ubuntu. Not sure what would cause that. Maybe someone out there with more knowledge will chime in. Good luck.
Here is a link to a temp cwm recovery and root instructions for a nuvision 8 inch tablet. According to the post it might work on other intel based tablets. Disclaimer: You may brick your device. I still can't establish an adb connection to test this. I have adb with the tablet booted. I lose it in fastboot or recovery. I was able to unbrick my nuvision after 2 years of waiting for a method.

Winblows 10. I think it's a driver issue.

I was wondering if it might be a driver problem. You could try Virtual Box and run Ubuntu that way. I may try that cwm down the road. Thanks for the info.
