Hi there,

I am trying to access my device (Zync Z930 tablet) in fastboot mode. Therefore I started it by pressing Vol Up + Power until blue light appears and connect it to the PC (running Lubuntu 64bit).
Verifying connectivity with lsusb results in:
Code: 
root@badday-mobile:/home/badday/Downloads# lsusb
(...)
Bus 002 Device 011: ID 1b3f:8300 Generalplus Technology Inc.
So the device seems to be present. I also added /etc/udev/rules.d/51-android.rules with
Code: 
SUBSYSTEMS=="usb", ATTRS{idVendor}=="1b3f", ATTRS{idProduct}=="8300", MODE="0666", OWNER="badday"
and made sure that rights are correct:
Code: 
root@badday-mobile:/home/badday/Downloads# chmod a+r /etc/udev/rules.d/51-android.rules
root@badday-mobile:/home/badday/Downloads# service udev restart
However, fastboot does not find the device:

Code: 
root@badday-mobile:/home/badday/Downloads# ./fastboot devices
root@badday-mobile:/home/badday/Downloads# ./fastboot -i 0x1b3f getvar VERSION
< waiting for device >
As you can see I am running it as root. When booted normally, device is recognized (of course with different vendor ID etc.) with adb and I can make it boot to recovery mode, but not to bootloader mode. Trying to do so will result in a normal reboot (from what I can see).


Anyone having some idea?


Thanks a lot,

badday

Some additional information I found out:

Try to reboot in adb via "reboot-bootloader" results in normal startup. Furthermore, booting to fastboot mode (with vol-up-button down) with Micro-SD-Card inserted makes the device not to appear any more in lsusb.

Anyway, that made me having even less clues than more

I'm not sure for linux but I think you will have to download drivers ,,,,,,,I had to do this for my computer (running win 7) to read my phone in fast boot

I downloaded an app called driver tools and that fixed it ....hope this helps

Ps : It maybe that your running 64 bit Os

@abdulmomin, jaydeepkhalpada: Rooting thread can be found here: http://forum.xda-developers.com/show....php?t=2028740

@fredworxz: Yes, I use a 64bit OS. However, for GNU/Linux drivers should not be needed as adb runs out of the box (please correct me if I am wrong).
