Finally, I had enough time to read almost the whole discussion and to flash my device.
I report here a summary for new users in order to save their free time:

Change country code and other parameters

uci set luci.main.lang='en'
uci commit

nvram set CountryCode=EN
nvram set ssh_en=1
nvram set uart_en=1
nvram set boot_wait=on
nvram commit

Flash INT firmware

ubiformat /dev/mtd12 -f /tmp/r3600-raw-img.bin -s 2048 -O 2048
nvram set flag_ota_reboot=1
nvram commit
reboot

Now the router seems working well with latest INT firmware 3.0.22. I found a possible problem that I was not able to solve. If I try to use the router in repeater mode (wireless) I am not able to connect it to any other device.
I get the error: Couldn't test wireless repeater
Any idea?
