I found this Jellybean rom by Oma. It was originally for the Loox but they supplied some fixes for other devices as well. I tried it myself and I haven't encountered any errors at the moment. 
To install
1. Download the rar from this link:
Oma JB 4.1.1 v1.2 for Arnova 7G2 repack by Vrailink.rar (293.9 MB)
https://mega.co.nz/#!CxgVQTbR!Hrx1qjGpaIixBms858YbQEOijkZ3kS3H7dr8N_WZ_FE
2. Connect your device through usb and push the power button to lock position.
3. Wait for windows to recognize your device
4. run RKAndroidTool.exe as administrator
5. Erase IDB
6. Run
7. When everything is done start your device and wait until it boots into recovery.
You'll get some cache errors but that's ok as this will be fixed in the next steps.
8. Mount the sdcard and copy all the rar files from the folder 'copy to sdcard'
9. Now go to install zip from sdcard and install the rar files in this order:
    1. Oma JB v1.2 Format NAND.zip
    2. Oma_JB_v1.2_akkufix_2.zip
    3. Oma_wpa_supplicant_adhoc.zip (install this if you wan't to connect to adhoc networks)
    4. Oma_JB_v1.2_Modell_fix_Arnova 7G2.zip
10. reboot your device, wait for approx. 5 min and enjoy
I just assembled all the files in one package for an easy install. All credit goes to Oma and CrewRKTablets. Don't post any bugs or problems you encounter here as I cannot fix them. If you want more info on this rom go here:Â http://crewrktablets.arctablet.com/?p=118

Unfortunately no I don't. But this storage is only for your apps. Most Arnova roms have a max of 2GB for apps installation so it should be sufficient 
If you want more space for your apps maybe you can look into apps2sd?

What's wrong with the link? I don't know I only have the 7G2 but you can try for yourself 
As far as I know the 7G2i is not so different from mine

You should read again the tutorial posted, where it does not say to put the zip file with the firmware on the sdcard or internal storage.

I'm talking about patches from the point 9. (Oma JB v1.2 Format NAND.zip ,etc....)
I can boot into JB, but WiFi doesn't work at all, and sdcard can't be recognized and some other troubles...

Have you used the RESTORE option when you flashed or did you formated the NAND how it is specified in the first post ?

The problems are normal. They will be fixed with the zip files. Try rebooting in recovery and install the zip files from there. If that still doesn't work then reinstall recovery with rkandroidtool. I hope this helps

Have already tried to boot from working JB into recovery and install ziped patches, but no luck. I have also reflashed the firmware at least 4 times... no luck... Also I have tried different microSD cards... but it still hangs on "Opening update package…" I can click buttons on the bottom, but they just got highlighted and nothing more....Â
Can it be 7G2i specific... actually 7G2 & 7G2i are identical.... Â maybe it is CWM problem? Have you saw newer version for our tablets? Thanks for your help guys!

I have erased IDB, after it is succeeded i have clicked on Run. There is no "Restore" in RKAndroidTools.Â

Maybe this one? http://forum.xda-developers.com/showthread.php?t=2173863
I haven't tried it myself. You dont have to reflash the whole mod just flashing recovery should be fine. Good luck
