A quick google search on the board returns THESE RESULTS (http://www.google.com/search?as_q=hermes+spl+downgrade&hl=en&num=10&btnG=Google+Search&as_epq=&as_oq=&as_eq=&lr=&cr=&as_ft=i&as_filetype=&as_qdr=all&as_nlo=&as_nhi=&as_occt=any&as_dt=i&as_sitesearch=http%3A%2F%2Fforum.xda-developers.com&as_rights=&safe=images). Or you could look at the spl downgrade guide HERE (http://www.mrvanx.org/cms/index.php?option=com_content&task=view&id=59&Itemid=27).

I'm having trouble downgrading too.

Following mrvanx's guide, I downgraded to Hard SPL 1.10 with no problem. But when I try to downgrade to either 1.04 or 1.06, I lose the ActiveSync connection, the phone never enters bootloader, and I get an error message from the RUU saying that the connection was lost.

After several hours trying everything I can think of, I'm officially stuck.

Any thoughts?

I had same problem yesterday. In CustomRUU you need to set Unsafe SPL it is the only solution for downgrading SPL. ATT: SPL 1.04.nbh

I downloaed the Custom RRU file, but what is the next step?
(I copied the .nbh file as "RUU_signed.nbh" and the .exe file to the PDA, and I run it, but with the colored sreeen it freeze.)
Now can I run the ROM update?
