no solution for E6750 degrading?

[rainmannn]

Hi guys, this is Adam with a ht e6750w, bought recently. I am new here.
I found this fantastic forum when I tried to get rid of cinavia on my bd.
I followed the DNS trick, but unfortunately the firmware I received is v1090... not working on my bd.
there is no solution for e6750 by now? (I saw some lucky guy completed degrading, but those are D6750...)
where can I get some custom firmware in this case? checked around the forum, also a bunch of E6750 are in trouble with CINAvia but nobody replied the threads.

thanks in advance...

desperately
