how to rename a site without accessing the Central Admin if there is a treshold...

SP2010 - I'm SCA of a site collection...

I need to rename a site, (site settings, title etc), but when  I rename and try to save, it says   "The attempted operation is prohibited because it exceeds the list view threshold enforced by the administrator."

ok I understand the problem, but I don't have access to Central Admin and increase the Treshold or whatever.

I need to do that within the Site collection  - I've rights use Sandbox solution.

Please advise how to rename the site?  (LINK)
