Hi,

Like many others I've a C93A with a beautiful black screen at startup , I can see that the backlight switch On but nothing more.

I've tried to install many ROM without success

I've open the tablet to disconnect the battery to discharge everything , on the the motherboard It is written ZT292-C93S-V1.1 05052013.

I've seen some post about sdcardmaker but I don't understand how to use it.

Thanks for your help

Sorry my man but you are out of luck. I too have the same problem and have tried

all I can muster on my software knowledge. Since you have the unit open, there is

a post about shorting pins 5 and 6 together while booting up.

google how to unbrick your Amlogic AML8726-MX Series Tablet. there is a video and instructions

good luck and let us know if you tried it and if it worked for you. I continue software research

You mentioned in the C93 forum that you have a C93S... So do you have a C93A or C93S? If it's an S version, you should be flashing the 0626 ROM for the C93S - http://www.zenithink.com/Eproducts_C93.php?download

10.1" C93 (1024MB+8GB) Android4.1 2013-06-26

This version suits to C93 model with barcode C93S-xxx-8GB-ZNSxxx-xx. Android 4.1
Resource Update
  • Current version update:
  • This is the first release for new model of C93.
  • 1. Update the power-on delay to more than 5 seconds.
  • 2. Add Sound Recorder app.
  • 3. Add Screenshoot function.
The method of firmware installation for this model

Using TF card

  • First extract the firmware which you get or download, then copy the whole "zt-update" directory into the root directory of TF card.
  • Put the TF card into TF card slot, then press the "Back" button at the same time to press the power-on button, then operate as per the reminders shown on the screen, the machine will be installed the firmware and then reboot.

Note: keep charged when the machine is being installed the firmware. Please hold the "Back" and Power-on button for at least 5 seconds.
If you flashed the wrong ROM for your tablet, it could have gotten bricked....
