I was able to login by making these step:
1) Create directory /user
2) change admin password from cli
3) restart rpcd (/etc/init.d/rpcd restart)
4) restart uhttpd (/etc/init.d/uhttpd restart)
5) remove ip_blockd package (opkg remove ip_blockd)
I have removed ip_blockd because I see this in the log (with CLI command logread)
