Teclast X98 Air charging problems AND Workarounds (no 3G, no II) topic

Hi !
I had 2 Problems (running Win 8.1):

First: it only charged when OFF, not when windows booted.
Then: NO Charge at all after playing with a USB Hub (nothing defective, just unplugging and replugging).

I solved the NO CHARGE Problem this way:
I opened it, unsoldered the battery (easy, 3 wired, PLEASE isolate them, do NOT short the wires).
Then i sortened (bridged) the 3 solder "blobs" on the PCB with each other to drain remaining capacity from the "confused" charger chip i wanted to reset.
Then resolder battery, BAM, it works again.


My first problem remains --> only charging when OFF, but as i now have an AMpere meter conneted all the time i guess i have the solution !

My battery profile has a low brightness, my "powered" has a high brightness. So if the X98 detects the charger it starts charging (i can see around 1 Amp flowing) and turns up the brightness. BUT the bright screen drains so much power that the Voltage drops and the charging circuit senses that and thinks chargin is over and stops charging.
If you have around 75% brightness this goes on & off forever, my Ampere meter jumping between 1 Amp and 0 Amp all the time, brightness going up and down.

Solution (Well workaround): Set the "powered" brigthness to a low value and ENJOY charging.

Maybe Teclast can solve that via Firmware. If they care...

Greetings,

Nils

P.S. if that helps or you have a better Solution, PLEASE post here so we can see if that is just me or if this is a general situation !!!

Teclast x98 Air II : 3D Games Freeze Issue now have temporary solution topic

I bought the tablet back on December 2014 with Android 4.4.4 installed. My Teclast x98 Air II model Is (HG6M). There are 2 major problem on the tablet :
1. The playstore will force to close
2. The most critical problem : I cannot play most of the 3D Games, especially those heave 3D Games. I know many user face the same problem.

After month of attempt to contact the Teclast company and seller in Aliexpress, finally they release a solution.

Solution 1 : Play Store Issue
1. Teclast have release a firmware update especially for Teclast x98 Air Series Tablet. You can use the build in TeclastUpdateTool to check the firmware update.
2. If you fail to update (just like me), then you have to manually download the firmware and use the factory flash tool to do a clean install. Meaning all your data will lost, please backup first before proceed.

3. sorry they are all in chinese.. When the page load click on the right hand blue color text. Then it will bring you a new page to enter your model number.
3. Download the firmware

Solution 2 : 3D Games Freeze Issue
1. Download a file from this link : http://pan.baidu.com/s/1pJ9LjTL
2. Then use the build in TeclastUpdateTool to flash the file.
3. Reboot the tablet and you will find that a new apps call [Fastmode] installed in the tablet.
4. Every time before play 3D Games make sure the fastmode is enable.
5. Note: if tablet have reboot, the fastmode will be disable. So you have to enable it again before play 3D games.

So far with the fastmode apps , i never have any problem playing heavy 3D Games. Hope this will help those who been looking a solution for the major issue. I consider myself lucky, as the seller able to help me get the solution from Teclast.
