Hello,
I may be in the wrong section to post this , if so please let me know.
I just bought an Arnova 7 G2 8Gb tablet from a retail chain in Belgium, the device was sold with Android 4.0.3 out of the box (nice sticker on the box was added to mention it).
I have tried a few things to have the Google Play app working, without success. In a nutshell :
- Install Google Apps manually : Error message when installing google framework, gmail market etc would install, but quit at launch.
- Using arctools : Error message when trying to install App Packages (error 20/28), no firmware to chose from the list.
- Putting update.dmg with Fenice's firmware at the root of my device (internal storage, could not put it above) : Tablet never offered to install a new firmware as described on Arnova's page.
My questions :
- Would anyone be interested in a ROM dump of that tablet sold with 4.0.3 to mod it ? If so, an explanation on how to proceed would be nice
- Have i missed something in the steps described to try getting Google play working ?
- Why isnt there any firmware more recent that Jan 2012 for that model on Arnova website, as this one was installed on the boxed product and is more recent ?
Thanks !
Thanks for your post Oream, that's nice to see someone finally getting hold on these Arnova 7 G2 ICS tablets
Please don't try to flash anything, you could corrupt the exist ICS firmware and make it not dumpable.
You should no problem to make the dump using the 2 links exelletor gave in post #2, if any issue let us know.
Cheers.

Hello lads,
It's been a while since my last post, but i'm done moving apartments now ! First things first, pictures of the product :
Sorry about quality, iphone camera + bulges under plastic film + shitty lighting = this .
Next step : dumping that ROM using exelletor's instructions
Realy cool. I think you can do it. Good Luck and YOU must remember - we are your friends

Hi All,
So, I'm done installing the 312354315234213 apps required for the dumping, I went thru exelletor's tutorial for the dumping aaaaaand... i'm stuck.
Long story short, I was able to connect to my Arnova 7 through command line, found the block containing the backup, but my issue started when I tried to use the
/sdcard/rkdump /dev/block/mtdblock4 /sdcard/update.img command, which returned an error message saying 'permission denied'.
To get around this and following the comments under the tutorial, I went instead for /data/local instead of /sdcard to store the dump, changed permissions to 777 for rkdump once there. This time no error message, there you go, CRC, done.
My issue now is, apparently a dump got created, but I don't know how to get it back on the computer -_- Went to the Arnova settings, disabled the USB debugging, tried to get it from My Computer > Arnova, but I don't see it anywhere there.
I'm pretty sure it's very close at this point, any idea on what I could have missed ?
Edit : When checking with the file browser on the tablet, the dump created appears at the root of internal storage. I thought of uploading it through the at-upload page, obviously Android does not offer me to pick it up since it's not part of my photo/audio/video library. Trolololololooo.
That's great progress, nice.
Well you can probably use File Explorer (or whatever the application name is) to copy the update.img file to the right directory.
Or you can use your command line again from the computer, from the directory having adb:
adb pull /sdcard/update.img .
This will retrieve the update.img file to the local directory where you launched the command on the computer.
Cheers.

Cheers admin, I did not have to use the pull command (was a bit lazy to put the whole thing back into debug mode) but just moving update.img to /sdcard/downloads did the trick.
I'm currently uploading it through the at-upload page
Couple more things :
- I would be interested in understanding the cooking process, are there any tutorials out there explaining how to modify exisiting firmwares ? I'm especially interested in how Google Play can be trumped
- Do you need the lines I added to winusbinfo to make it work with the Arnova 7 G2 ?
- The exercise of dumping was quite refreshing. I would recommend it to anyone who has touched linux/shell in the past but forgot most of it, that kind of hands-on is fun !
