Why do we do this?

I have Radio 5.69.09.05a_22.50.50 and bootloader 4.3.2250
I want to flash RSPL and then DFT ROM, but as I see I need to downgrade bootloader

If I flash Radio 5.66.09.09_22.46.50 from Mondrian Cingular 1.52.502.04 file on my device , will it brick it? can I flash 5.66 radio over 5.69? to downgrade bootloader?

Radio controls one's device's connectivity strength & quality... i.e. cellular signal & strength, etc.

Downgrade OSPL so that one could XSPL.

only Mondrian Cingular Shipped ROMs have been leaked...
attempting to flash won't brick your device unless something goes horribly wrong.
flash might fail because of an invalid vendor id, though, if one's device isn't Cingular branded.

Does anyone have a Telus radio?

You would be better off finding an original rom with the lower radios and going that route. At least that's what I did going from 4.3 to DFT. Found the original 7004 signed retail rom flashed that then did the RSPL->HSPL->DFT rom

V4 is amazing for the surround btw

Using this RUU http://forum.xda-developers.com/showthread.php?t=860842
can i use same above tutorial to downgrade ?
Im at 7390 or 7392 something atm
And im guessing above link is 7004 right ?
