[ROOT] Teclast Master T8 - Android Q&A, Help & Troubleshooting

Hi everyone,
This is what I have done to root my Teclast T8 with Magisk (based on this chineese forum: http://tieba.baidu.com/p/5449087481)
1-First download the official firmware from Needrom.com (You need to register): https://www.needrom.com/download/teclast-t8-e8c1/
2-Go to the Firmware folder and copy the “boot.img” file to the root directory of your tablet
3-Download and install MagiskManager on the tablet, click on Install, then choose to patch the boot image file. Choose the boot.img you’ve just uploaded to your tablet and it will start to automatically patch it.
Then go into the File Manager and go to the MagiskManager folder and find the “patch_boot.img“ and copy it to the root directory (without copying it to the root directory, you can not find the file from your pc…), then sends the file from the tablet to your computer.
4-For me the method with SP Flash Tool don’t work, because it says the scatter file is wrong (don’t know why…)
So i have to do it with adb and unlock the bootloader first:
-connect the tablet to pc, (first you have to enable OEM unlocking and USB debugging in Developer options)
-reboot the tablet in fastboot mode, hold buttons “power+Vol +” at startup, choose fastboot mode with Vol+ button, valid with Vol-
- open a command prompt in adb folder, then “fastboot devices”, then “fastboot oem unlock”, it should say “OKAY, finished”
Your bootloader is now unlock.
-then copy the “patched_boot.img” in the adb folder and tap in command prompt “fastboot flash boot patched_boot.img”, then “fastboot reboot”.
Your tablet should be rooted.
I think you can relock bootloader after... don't try yet.
PS: This is my first thread, so be indulgent ?
Don’t ask me technical questions because I am not a developer , just a simple user …
Hope this will help.
If someone find a way to find and flash a TWRP or how to install Xposed, please tell me, thx.

Rooted using same method but SP Flash Tools worked in my tablet.
Waiting for a TWRP ....

---

Yes, can confirm that method works for root.
Also tried the T10 TWRP and it's not working on the T8, just a black screen.
Don't need TWRP yet, some bugs in the ROM are more annoying than that

Flashing ROM with SP flashtool - Teclast Master T8 (E8C1)

Hi! I haven't used in built update app so I'll try to explain how to update using flashtool. Follow the steps with your device disconnected from the pc and take into account your files will be erased.
First of all, I recommend you to install ADB and fastboot drivers: 15 seconds ADB Installer
As OP said download the rom from NeedRom and unzip it: You will have three folders:
升级工具, which contains flashtool
固件程序, with the rom
驱动程序, with the drivers
Rename all of them as flashtool, rom and drivers, for example. If you don't, you may have troubles launching flashtool or loading the scatter file.
Launch flashtool as administrator (升级程序, you could rename it too), if you get the message "The scatter file cannot found, please make sure the file exist before download" ignore it. In flashtool make sure MTK_AllInOne_DA.bin is selected as Download-Agent and select the scatter file inside rom folder as Scatter-loading file. Choose firmware upgrade from the list and click the Download button (the one with the green arrow).
Finally, switch off your device and connect it to your pc. Flashtool should do the rest, wait untill "Download Ok" message is displayed. Close flashtool, disconnect your device and switch it on.
IF your computer doesn't load needed drivers automatically, flashtool won't start the process as expected. You will need to open device manager on windows, right click on your device - update driver - choose manually - browse "inf" folder inside drivers folder (choose x86 or x64 according to your OS).
Hope it works! Good luck.

Prevent Brick and Xposed for Teclast Master T8 (E8C1)

Hi Polo19!
Thanks for your post, I rooted my tablet following it! But since I encountered some issues in the process I wanted to share my experience.
IMPORTANT: For a few hours I thought I hard bricked my device, so I hope I could help somebody.
When patching boot.img with MagiskManager IF the app automatically tics "Keep force encryption" choose "Keep dm-verify" aswell!
I don't know why but this was the only way to make it work on my device, I kept getting a encryption error after flashing the patched boot.img, despite the fact that I have never encrypted my device.
After getting that error I tried to flash the clean rom again, but flashtool gave an error and the tablet completely died! Well, it seemed so.
It's pretty stupid but the only way to make it work again was pushing the reset button on the top right corner of the tablet for a few seconds and flashing the rom again.
About Magisk: use the OFFICIAL MAGISK XDA THREAD to download it, as https://magiskmanager.com/ is NOT the official website.
In step 3, I couldn't find the patched_boot.img file even after moving it to the root directory. So I had to (let the patched_boot.img file in the default directory):
Install ADB drivers in the computer: https://forum.xda-developers.com/showthread.php?t=2588979
Enable USB debugging in developer options in the tablet, connect it to the computer and accept the connection.
Open command prompt / powershell: "shift + right click" wherever you want to copy the patched_boot.img and open cmd or power shell.
Run the command:
Code:
adb pull /sdcard/MagiskManager/patched_boot.img
In step 4: you won't encounter that problem if you rename downloaded folders and get rid of chinese characters. Simply open flashtool, choose the scatter file, untick all options except boot and change the default boot.img with the patched one (I renamed it to boot.img, I don't know if it's necessary)
Xposed: you can install xposed using MagiskManager.
Install Xposed Installer for Magisk, go to download tab in MagiskManager and install Xposed SDK24 (for android 7.0) and reboot

Just need TWRP and I'm happy.
There's a chinese TWRP but it's not working decently.

Yes, i also install Xposed using MagiskManager and it works. Now i am able to use all fonctions of Greenify, Amplify, Powernap and get a pretty decent standby batterylife.

Hi, I tried to follow the procedure but in ROM 1.10 doesn't work
---------- Post added at 01:37 PM ---------- Previous post was at 12:44 PM ----------
With the news roms doesn't work...

What is the rom that was working this WA??
Thanks!

I just did this to a tablet that had OTA'd the 1.10 - using the 1.10's downloaded boot and latest Magisk Manager 5.5.4 / Magisk 15.3 beta
OEM Unlock, patching boot image and patched boot image flashing worked
BUT - the included Magisk Manager does not launch after installing upon reboot...
HOWEVER - V5.5.3 of the manager did work.
$ adb -s 0123456789ABCDEF install MagiskManager-v5.5.3.apk
Success
$ adb -s 0123456789ABCDEF shell
t8_e8c1:/ $ su
t8_e8c1:/ #
Notes
1. Tablet is wiped
2. Boot delay of 5 seconds is added with "can't be trusted" warning in white text
3. Fails safetynet
Letting MagiskManager update itself to 554 also worked - so I think my method of just installing the apk from the Magisk zip's common folder was wrong.

Hi,
My T8 arrived yesterday and I've used OTA to update to 1.10.
Is the sptools method working with 1.10 or do I need to use this process?
Also where to the numbers 0123456789ABCDEF come from in the instructions I've quoted?
Thank is advance

---

i have the ota 1.10 update and the rooting was successful. magisk and xposed working flawlessly.

---

another point:
i have closed the bootloader after flashing the patched boot.img with "fastboot oem lock".
the device boot up is faster and the warning "...5 seconds" is gone.
now, i wait for twrp.

---

You dont need to unlock bootloader.
Just flash patched_boot with flash tool.

The suggested worked for me. I will also mention that you must be connected to the internet to patch the boot.img file with magisk manager (otherwise, the option will not be presented in the magisk manager GUI).

Were there made any changes for the fingerprint? Soimebody mentioned, it isn´t that good. Maybe the last updates change something...
