Hi,
I am waiting on delivery of a C71 Upgrade tablet, after reading on these forums I was wondering if there are custom roms and kernels for it.
I do have a ZT280 C91 that has the 900mhz kernel.
I was also wondering if there are any problems with the C71 that I should be aware of.
Thank you
Regards Granny1

Nope. It's pretty much the same. It charges through the USB port now which is pretty awesome and it seems like the CPU is on demand and lowers to 300mhz when not in use. Which it could have been before but I never checked.

The resolution? The ports?

YEa that was me. And it is verified they definitely charge by USB. I'm pretty sure one is OTG and the other is a host. I don't know why they would change it.

yes, you must keep to aware of some problem after upgrading, but don't forget to create backup to prevent data loss caused damage.

I can confirm that charging over USB works fine. A bit slow since USB can only supply a max of 500mA.

No I'm in New York City. I bought mine in Shenzhen from an Aliexpress store. I was there 2 weeks ago that's why I was able to get mine so fast.

Hey kecikhebat,
I can verify that the mic does work. I tested it with google talk, and it worked just fine. Hope that helps you out. If you have another application you would like me to test the microphone with, I'll be more than happy to.

I've had two of these babies for two days and really pleased. Great product, everything works as expected and the only thing I see not as good is, obviously, the screen (which is good but still lcd and with a bit of mirror effect). Other than that, there's nothing not working. With the Mali400 it outperforms my Nexus S in 3d games by quite a bit.

By the way, updated one of them to the last oficial firmware version (dated april) and added functions and improved battery, but the rotation animation is a bit screwed... it was smoother in previous firmware.

everything works as expected


I see two unexpected issues:

  • The accelerometer isn't working for most applications. With the original firmware there was a racing game which worked, but with the latest firmware that is also gone.
  • The USB host port isn't visible to android. The Linux kernel sees USB devices and can e.g. use Mice, keyboards etc, but the Android USB host API doesn't seem to be able to access those.

Do you guys have the same issues? Has anyone e.g. managed to use other USB peripherals then Mice/Keyboards/Mass-Storage ?

Mine is updated to last firmware version (06/04) and has no problems with anything:

- accelerometer works flawlessly (tested with game raging thunder 2)
- usb ports works with periferals and mass storage without doing anything
- my Belkin blueetooth dongle also works plug&play, tested a file transfer from phone.

Also, i was able to change the kernel to the 900mghz one.

"Raging thunder" is the game i mentioned that came with the tablet. But e.g. temple run doesn't work.

And yes, peripherals like mass storage and hid work as this is handled by the linux
kernel. But the android host api (similar to what libusb is for linux) doesn't see
the devices.

A belkin dongle works? The bt dongle i tested (a D-Link DBT-120) didn't work.
