Why is my touchscreen not working after firmware upgrade?

There are currently two revisions of P76ti. Rev 1 & 2 have the same hardware specification except that they use different touch controller. Revision 1(earlier release) has the Goodix controller while Revision 2 use FocalTech controller. Rev 1 ROM are not compatible with Rev 2 ROM while Rev 2 ROM can be use for Rev 1 as the ROM contain both touchscreen drivers.

My Tablet has hung and is not reponding

Hold the power button for more than 8 seconds to force shutdown.

Hello fratello, welcome to the forum and congratulations on your new tablet. Before doing anything with the tablet I'd suggest you click this link http://www.androidtablets.net/forum...-one-guide-how-start-your-android-tablet.html for some general information regarding getting started with a new tablet.

The answer to your question depends on the brand of tablet you have. Some can be used while charging, like my Nooks and some can't. Hopefully someone with your brand will reply here with a definitive answer. If not, check the owner's manual in the section about charging the tablet. That's usually where they tell you if you can or can't use it while charging. If you don't get a manual, or it's printed in a language you can't understand, see if the manufacturer's website has a FAQ or place to ask questions.

Enjoy the forum and your new tablet!

Thank You for reply !
I am an "old" user of tablets... My previous tablets was : LY-F1 (can use while charging), ZTPAD 280-C9 upgrade (idem), EKEN T01 (canot be used ...). Now I buy this for my son, as a gift for great results at school !

Now I buy this for my son, as a gift for great results at school !

You must be very proud fratello, congratulations to you and your son.

 

[fratello]

Thanks, I am indeed verry proud !
I just received my Teclast ! First impresion : the screen it's "harsh", not "soft" like my previous tablets , the fingers dont move smoothly ... The construction it's ok, speed reaction seems to be good. I will try tomorrow if can be used while charging and I will post the results ! I will try the Gameloft/EA Games too... Regards !

 

[fratello]

Answer to my question : tablet it's unusable while charging ... Maybe because of charger (through mini-USB port) ?!
I am a little dissapointed ... LY-F1 not have this problem. This is it !
I tried : Air Attack (1&2), TurboFly 3D, Shine Runner - working. I have not tried yet Gameloft/Ea Games.
Regards !

Thanks for coming back to let us know fratello. Sorry it didn't work while charging, but your son still has a nice prize for his hard work at school.

 

[fratello]

I just tried ...and I can confirm : work fine while charging trough USB-port (even ratio of charging it's smaller). I think the problem it's in charger "hardware" ... I read that changing charger solve the problem !
Thanks for support ! Regards !

 

[fratello]

...and the response from TECLAST : " The tablet is unusable while charging. It's because of charger. "

 

[fratello]

I will try to build one charger, like this : http://cdselectronics.com/Kits/USB_Charger.htm
What's Your's opinion ?

 

[fratello]

This is how original charger look ... It's not an "elaborate" schematic ; not protected output (just one Zenner diode) ! Low cost

charger ...

 

[Spider]

Looks good, as long as the output 5V matches that of the stock charger and the polarity is correct. You certainly are determined to use that tablet while charging it.

Since the battery of this tablet it's rated at 3200 mAh (see : http://www.androidtablets.net/forum/teclast-p76ti/35048-teclast-p76ti-review.html) I think (Mr. Spider have right !) to build one charger, using constant current charging ; I adapt the schematic for 0.3 A current charging (1/10 from battery capacity - low charge ratio). I will post the schematic. Regards !
