It´s a bug in the Android ROM that it´s only recognizing an USB-device if it´s pluged in at boot. So plug it in, leave it there and reboot to Android and probably it will be recognized then.

Flashed relevant images via fastboot. Everything okay, working smooth. Thanks mirek, great job!

Guys,

afais your problem exists because your tablets is not recognized by Windows. This is a driver problem you have to solve. There are some hints in the forum, I can´t help you there as on Macs there aren´t any drivers to install to get fastboot to work.

But maybe, if you have your drivers installed, you can choose Android in the dual boot menu and afterwards push both volume buttons at the same time. This should bring you also to Android bootloader. It´s easy to know it because it´s the one with the green Andy. Try to use the fastboot devices command to check if your Windows recognize the tablet there. My Mac doesn´t do it, that´s why I always have to boot loader.efi from dnx fastboot mode.

You can also try to flash the new ROM from mirek if you get the flashtool in Windows to run, but this will delete your Android data. I hope you will get your Android up again.

Hi,

you can use this one for rooting the tablets Android via TWRP. Just klick at “Install”, chose the enclosed zip and after a reboot you´re rooted with SuperSu.

Cheers!

Hi Daniel,

long story short: you don´t have to root anything, because your goal firstly is to restore Android. Rooting means you give yourself Superuser-rights in Android, but you don´t have a working Android, so there is nothing to root. You can do that once your Android is up again, but that´s a different story.

And you need the 3 files I mentioned, loader.efi, boot.img and system.img. The first one (from valerima/vasabe) is needed for booting into Android bootloader and the both other ones (from the large zip) are system-images of Android, because most probably one of them or both are corrupted on your tablet. That´s why Android won´t start. You will only substitute your corrupted ones with the extracted undamaged ones. And that´s why you need fastboot(.exe). It´s the tool that does it for you. But to make your tablet listen to these fastboot-commands you type in your PC you must boot your tablet into dnx fastboot mode and afterwards in Android bootloader mode. Imagine these two modes as maintenance/repair modes. Just in these you will get through with your commands. If you connect your PC with your tablet while an OS is booted on your device, you can do nothing with fastboot(.exe).

So now I guess you have enough information to bring your Android back on track. Cheers and have fun!

TWRP is working fine here on a K9C6, backup and restore, all good. Also flashing a zip was successful (rooted Android with SuperSu_2.46.zip). Thanks to Dani, you did a real great job!

Hello Daniel,

you have two partitions on your tablets harddisk, one for Windows and one for Android. If you follow my instructions you don´t touch the Windows-partition, so nothing can get harmed there.

TWRP stands for Team Win Recovery Project, which has an own GUI (Graphical User Interface) and is used e.g. for file transactions or data backups in case Android is not properly working. You can also flash new Android ROMs with it and the “port” just means, that this one for the X98 Pro is ported from another tablet, as the TWRP-team still don´t support Teclast. The good news is most probably you will not have to use it to get Android up and running again.

But you will have to use fastboot(.exe). This is a tiny program without an own GUI which runs on your PC (not tablet) while you have a connection to your tablet via USB. The tablet has to be in dnx fastboot mode and later in Android bootloader mode (two different modes!). To install fastboot on your PC maybe this: http://forum.xda-developers.com/showthread.php?p=48915118#post48915118 helps you to do it easyly on Windows. If your PC is on another OS you have to google the installation. I presume you are on Windows. Once you installed fastboot you have a folder where the “fastboot.exe” sits. In this folder you have to copy “loader.efi”, “boot.img” and “system.img”. Due to the fact that fastboot doesn´t have an own GUI you have to open a command prompt (yes, the black one with white letters or another terminal program) in this folder (you can google this also how to do it). Afterwards you can type in the commands I mentioned above. The tablet must be recognized in the command prompt window in Windows. If not, your fastboot installation failed or you don´t have the right drivers in Windows. But that´s the point where my help ends, because I don´t use Windows anymore since years already.

If it is properly recognized the above mentioned commands should bring you back to a booting Android without touching your Android-data-section (your music, photos, whatsapp-conversation, etc.), so normally you don´t need TWRP. But just for the case something goes wrong and Android doesn´t boot up you can boot in TWRP (see commands at valerima, copy img-file first in the “fastboot-folder”) and save your data. The GUI is self explaining, under “Advanced” you will find a file manager which you can use to save your data (on internal storage) to an external sd card.

I tried to explain these few steps as easy as I could and I hope, it´s now doable without any specific knowledge. But if that is still too complicated for you, you should really think twice whether you want to do this. The risk is to brick your Android partition, you have to be aware of that. Good Luck!

There is an easy way to bring up your android again in combination with valerima´s post above. It took me 10 minutes when my K9C6 was stuck at the intel logo. You need the zip-file from here: https://drive.google.com/file/d/0ByUOEKnPRz9geTNIcDRPOFBzdVE/view?usp=sharing

Extract this zip anywhere. You need two files out of it: boot.img and system.img.

But first you have to know how to set fastboot right on your operating system. Aunt google is your friend. The easiest way is to copy the two files in the same directory where your fastboot-app resides (exe in Windows, I´m a Mac-user, I can´t help you any further in this way).

Once you made this you can go to point 3 of valerima. You only need power button and Vol- to get in dnx fastboot mode. It´s shown in small yellow letters above that chinese symbols.

Connect your tablet via usb with your computer. Type in: fastboot devices .You should get back a response name in the next row if your tablet is recognized.

Then go to point 5 of valerima and type this in after you downloaded the loader.efi and copied it to your directory. The tablet should boot now into android bootloader. Type again: fastboot devices .You should get a different name responded as in dnx fastboot. If that´s the case you´re on the right path.

Then type: fastboot flash boot boot.img (or the path where the file is)

Next type: fastboot flash system system.img (see above)   This will take a few minutes as it´s a large file, so stay calm.

Once it has finished type: fastboot reboot    and you´re done.

In dual boot menu choose android and give it some time, it took a few minutes to pass the intel logo here. But your android will rise again. If not you´re having a corrupted starting app probably. You can then choose point 6 of valerima and start twrp (it works very well on K9C6) and do a backup of your data to an external sd card with the included file manager. After that wipe your data section or reformat it to ext4 (this deletes all your personnel files!!!). You can restore your data later for example with a file manager. Nothing will get lost if you do it the right way, but as you always know, be careful as you can brick your android partition. It´s all on your own risk, so don´t blame me for mistakes you eventually make.

Hope that helps anyone.
