Hi folks,

I'm a new owner of an Arnova 7c and I'd like to put a custom rom on it.

I've read and followed this tutorial:

http://www.arctablet.com/blog/devices/arnova/adb-and-fastboot-tutorial/

Typing C:\Android\android-sdk\platform-tools\adb devices gives as expected

* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
0123456789ABCDEF device

But C:\Android\android-sdk\platform-tools\fastboot devices gives nothing.

When I start the tablet in fastboot mode (pressing Power and Vol. - until the four icons light up), I get a prompt for Windows XP asking for an "Android" driver. Pointing to android_winusb.inf (the lastest one including 7c) does not help.

What could be the problem ? Is it related to the winusbcoinstaller2.dll file ? Something I forgot to download in the Android SDK Manager ?

Thanks in advance for your insight.

download the superoneclick program, after that put the usb drivers drivers, open the program (superoneclicl) go to advanced/check drivers, and force install them, it should work.
you can try first whitout puting the arnova drivers in the superoneclick driver folder, to see if works ( i don`t remember exactly ,4 moths passed since then)

I had SuperOneClick already installed as I used it to root my 7c (it worked well).

I went to advanced and clicked 'check drivers' but it did nothing (same with checking 'alternate ADB parser'). I tried 1st in fastboot mode without putting the latest Arnova drivers into the superoneclick driver folder and, as it did not work, I tried it again with tablet turned normally on (not pressing Vol. -) but nothing happened either. Same thing with the Arnova drivers (one try in fastboot, one with tablet on), still nothing shows when clicking 'check drivers'. And iirc I even tried this in debug mode and in normal mode.

The 7c is "installed" as Android ADB interface, this part is OK, but not as Android. This is the driver Windows keeps on asking me when the 7c is connected in fastboot mode to my PC. Forcing android_winusb.inf does not help, as system says this file contains no useful info about the device.

PS: to install your 7c Glob ROM, do I also need this fastboot access ?

you need fastboot acces to instal the recovery, i can help you via team viewer today after 5 pm

Ps:When you install the drivers you need to have the device in debugg mode, you can activate that from settings menu/aplication/ development

Thanks for your help proposal through Team Viewer but I can't today.

I may uninstall the whole stuff and try it again, as I must have done something wrong in the installation process of SDK and/or driver.

You need:
-Java SDK
- Android sdk (put the path to c:)
-Superoneclick
-the device must have the debugg mode enabled
Install this .reg (http://goo.gl/wCCz) which allow you to open the Windows Prompt in the chosen folder by command in.
adb devices
adb reboot bootloader
fastboot devices
fastboot erase recovery
fastboot flash recovery (path to the file)
fastboot continue
Arnova will start again, put the firmware on the sd card, flash`it 🙂

I've read again the 'Tutorial on ADB and Fastboot' at http://www.arctablet.com/blog/devices/arnova/adb-and-fastboot-tutorial/

Super One Click is mentionned only once:

download the adb_winusb_driver.zip. Next go to http://forum.xda-developers.com/showthread.php?t=803682 and download “Super One Click.”

But what is its role in the process ? The tutorial does not ask to root the tablet so I'm confused (I've rooted my 7c even if it was not asked).

Is "Super One Click" useful for the drivers or are Arnova drivers good enough ? Maybe I missed an action there causing my problem.

Thanks in advance.

the superoneclick tools has an option that force installs your drivers, that`s why i use`it beseide the fact you can use the root function
you can try directly the drivers with which the superoneclick comes, and install does drivers, if it does not work, you junst need to put the downloaded drivers in the drivers folder from superoneclick, and install them.
I can help via team Viewer if you want., it is a 5 minutes job.
