Sencor Element 7 V3

Sencor Element 7 version 3 is a standard Q8 format, A13 based tablet.

= Identification =

On the back of the device, the following is printed: element 7 version 3

SENCOR&reg; Internet Tablet with 7" Capacitive display and 4GB Memory

The PCB has the following silkscreened on it: SAQ8-A13 V1.2

In android, under Settings->About Tablet, you will find:
 * Model Number: ELEMENT 7V3
 * Build Number: nuclear_evb-eng 4.0.4 GC0308_5370_1680_7660_MSM

= Sunxi support =

Current status
Not supported as such. Similar devices and drivers are supported. Hopefully will get it supported soon...

Manual build
You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.

Sunxi/Legacy U-Boot
Use the  build target.

Mainline U-Boot
Use the  build target.

Sunxi/Legacy Kernel
Use the file.

Mainline kernel
Use the  device-tree binary.

= Tips, Tricks, Caveats =

FEL mode
Both Vol+ or Vol- button triggers FEL mode. Though only ./fel version and LiveSuit/PhoenixSuit flashing works (no success entering Boot1 for me).

Wi-Fi Antenna
While you are inside your device playing god, it may be worthwhile to check the antenna (mine was a bit torn, possibly soldered on the wrong places and with shorted coax cable too and the pcb connection came right off and left some weird white residue behind on the copper pad - glue?).

To correct that, cut a whole new microstrip antenna from a copper tape (I used this design, but you can recreate or reuse the old one). Clean the old coaxial cable(or get a new one) and solder that back right this time. Cover the antenna from both sides with Kapton/polyamid tape and DONE. I gained about 15 db to the signal and it sure feels more reliable now.

= Adding a serial port (voids warranty) =



Device disassembly
Identical with Q8 Format disassembly. To access the PCB bacside, unplug the three flex cables and unscrew the three PH0 screws. Turn the board over(the poorly soldered wires will most likely come off by themselves anyway, so don't worry too much about them now), then remove the plastic cover glued to the backside.

Locating the UART
UART solder pads are in the middle on the back-side of the PCB. TX is the one closer to the USB port.

Note: I am receiving no output during boot or FEL mode; only serial_noise seems to work for me. It maps to /dev/ttyS1. The diagnostic pads are easily torn off from the PCB (maybe not suitable for soldering to). If despite that you decide to try for yourself, here's how: UART howto.
