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://xdaforums.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:

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

There's a chinese TWRP but it's not working decently.

Hi, I tried to follow the procedure but in ROM 1.10 doesn't work

With the news roms doesn't work... :(
[Android Q&A, Help & Troubleshooting] elbela:
What is the rom that was working this WA??

Thanks!
[Android Q&A, Help & Troubleshooting] Kerrnel:
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.
[Android Q&A, Help & Troubleshooting] Zaphodb69:
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 :)
[Android Q&A, Help & Troubleshooting] dreas74:

You dont need to unlock bootloader.

Just flash patched_boot with flash tool.

[Android Q&A, Help & Troubleshooting] ForgottenSolstace:
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).

[Android Q&A, Help & Troubleshooting] Zaphodb69:
Thanks for all the responses to my question.

I'm having an issue with patching the boot.img

I've downloaded and installed Magisk Manager (MM)

Once installed I start MM and a dialogue box comes up wanting to know if I want to install Magisk. Click yes and the next dialogue the choice is:

Download zip only

Patch boot.img

It doesn't matter which I choose - download zip only does nothing and patch boot.img lets me browse to the boot.img file....then does nothing.

What am I doing wrong?

I also followed the official Teclast YouTube video on how to flash the rom and get root. All it does is upgrade the rom - it doesn't provide root.

Any assistance would be very gratefully accepted.

Cheers :)

PS -

I uninstalled MM, rebooted, installed MM, rebooted then opened MM. Clicked on Install and selected patch boot.img

Found the boot.img file

MM downloaded the latest Magisk

A logfile then popped up with this -

- Device platform: arm64

- Extracting files

! Invalid Uri

! Installation failed

Any suggestions please?

I really wish TWRP was available.....

Edit:

I've just run MM again and opted to patch boot.img - failed again

Went into the MM settings and cleared the cache

Clicked Install, selected my boot.img

Magisk downloads again

And runs! I now have my patched boot.img!

Will flash tomorrow morning and hopefully have root access!

RESOLVED!

Flashed the patched boot.img file with so flash tools and now I have root!
[Android Q&A, Help & Troubleshooting] _Pinscher:
Hi fella's, will root remove regional restrictions so i can Netflix on the tablet?
[Android Q&A, Help & Troubleshooting] Zaphodb69:
Short answer - no.

Longer answer - Netflix detects your IP address for geoblocking. Using a VPN "may" get you around the block but Netflix is pretty good at detection of VPN usage.

Root gives you access to system files which will permit running software not approved or controlled by Google - like ad blockers.
[Android Q&A, Help & Troubleshooting] _Pinscher:
Thank you for that thoughtful reply.

So I'm in Canada and my T8 doesn't let me install some things, like Netflix. I go to GooglePlay store and it's not letting me download it.

Similar with WhatsApp, I can't download it. It's unfortunate as i use both of those apps and Netflix on a plane is why i bought this device.

So with Root, would I not be able to change some setting that would allow me to download these apps?
[Android Q&A, Help & Troubleshooting] DanielMix2s:
For me it worked to root the device. After that I downloaded the netflix app from netflix directly. Now Netflix works good on the device.

I wanted to update GAPPS, but this doesn´t word. So I think in the rom is the problem for the destriction for some apps on Playstore.

WhatsApp I´m not using.

Guys how looks battery life on yours T8 ? Died for me very quickly, and seems like charging is taking longer as discharging....
[Android Q&A, Help & Troubleshooting] nature boy:
5h, close to 6h of SoT, sometimes over 6h. Mostly web browsing and youtube, so wifi always on (plus VPN software that might drain a bit)

Charging with the suppiled charger + adapter is quick imo for a big battery, certainly not 5h. Don't have any charging numbers right now to help.

[Android Q&A, Help & Troubleshooting] bit_creepy:
Do not try to lock your bootloader after rooting your device. I have tried several times now and it simply erases your device and goes back to a factory restore state.

Got root OK but recovery has disappeared. I just get the little green android bloke. Have I made a mistake?

PS: Anyone else having random shutdown issues?
[Android Q&A, Help & Troubleshooting] Polo19:
After 5 month of use, i can say that i am a bit disappointed by this device...

Battery get pretty hot when playing games like clash of clans or clash royal, and when battery is near 15%, it goes down to 0% and shut down...

The battery life is poor when playing games, I think 5400mah is not enough.

Also the touchscreen is not very responsive, have to often tap twice...

No problem with fast charging, I use a qc3 charger and it works well.

Unfortunately, I think this device will not last very long...

Teclast T8 Bootlooping after flash TWRP

I rooted my Teclast T8 according to instructions here, and then saw that there was a TWRP build for Teclast T8.

I used the Official TWRP App to install TWRP, and then tapped "boot into recovery"

Now it is bootlooping and I cannot even shut it off using the power button.

Anyone know how I can stop bootlooping and get back into my device? Any tips greatly appreciated. At this point I am just waiting for the battery to die so it stops bootlooping.

Thanks!
[Android Q&A, Help & Troubleshooting] rondinelle:
Did you try the reset button in the top right of the tablet (little pinhole)? My understanding is that will wipe and bring everything down... otherwise I'd use SP Flash Tools - download official ROM from Teclast site, press and hold power (or maybe power and volume +) until tablet stays off, then use the flash tool to load the official ROM and download it your tablet (attach tablet to PC while power is still off).

Guess that answers my question about whether TWRP can be loaded - I was just about to try it too... wonder why they put the build up if it doesn't work?
[Android Q&A, Help & Troubleshooting] xivxivxiv:
I got back into my tablet after the battery died. My problem, it seems, is that I cannot get system to read/write. My boot.img and patched_boot.img are not getting copied to / directory. I get "read-only" error.

I tried

mount | grep system

# mount -o rw,remount /dev/block/mmcblk0p22 /system

Error: '/system' not in proc/mounts

So I am still trying to fix this partial root where nothing can be written to /

- 2.01 is not fully stabil. Sometimes apps hang and I have to reset the tablet. Maybe a factory reset will help but I did not try yet.

- I can't set the default launcher to Nova or Google Now. It now and then keeps asking which launcher to use.
[Android Q&A, Help & Troubleshooting] Kerrnel:
Seems quite unstable. Can't install Microsoft Launcher (errors out through ADB and Play Store). Crashes (stalls for 10 seconds, then reboots) doing random things like installing an app. Definitely a step backwards in stability. Does have the "Desktop Mode Function" in the prior post screen shot.

Teclast t8

It's a very nice tablet. :cool:

This works for the TECLAST T8.

Procedure should be the same for T20 (haven't got one yet).

On Tablet, get MAGISK.

On PC.

Download and extract firmware (download from manufacturer).

Copy boot.img from firmware to root of sdcard.

Rename original boot.img (optional).

On Tablet.

Install and Run Magisk to patch boot.img file (result: boot_patched.img).

Rename boot_patched.img to boot.img

Copy to PC.

On PC run flash tool. Select scatter.txt and firmware.

From the list of files, click boot.img and browse to your patched boot.img file.

Click on DOWNLOAD in flash tool.

Shutdown tablet, unplug USB.

Plug USB back in, flash tool should start.

Rooted.

PS.

From memory, so I think this is correct.

TWRP Does not work at present (Screen flashes in recovery mode).
