Cingular ROM with 1.20.31.10 radio? - 8525, TyTN, MDA Vario II, JasJam Software Upgradin

I have "original" Hermes with 1.18.255.3.
I would like to upgrade to Cingular 1.31.502.1, as it has the latest OS version. Is there some way how to add radio 1.20.31.10 to this ROM, eventhoug it is using 1.06 bootloader? Cingular radio is 1.13.00.00, which is even older than the one I am currently using.
Thanks for any hints.
If this is not possible, I will upgrade to Cingular 1.34.502.1 or i-Mate 1.31.305.2 (preferably).

Yes you can flash 1.31 rom with 1.06 bootloader and then downgrade the bootloader to 1.04 and then flash the 1.20 radio.
I will update the wiki with better instructions on downgrading to 1.04 bootloader when I have some time.

Allright, will try it. Thank you.
Btw, did you you try this upgrade ROM - downgrade bootloader - upgrade radio path already?
