Default Denon 4308A vs Denon 4308CI-an idiot's oddisey

I feel like an idiot.
Short story long: I bought from Germany in 2009 a Denon 4308A. After a little use had to move in US. Since I got the unit for a good price, without checking with Denon I shipped it in US thinking that I will figure out a way to use it here.
Well after I arrived I learned about the fact that frequency CAN NOT be converted and a receiver will NOT work only with a step-up transformer , per Denon, another great idea popped in my head. Since Dnon has separate power boards, why not change the power boards from a non-working 4308CI to my 4308A?
One week ago I saw an ad about a firmware UPDATE failed 4308CI for 225. I went for it. Unit arrived. Upon opening both units, I find out that , at a firs visual, even logic boards are different, not only power boards. One has XM radio and multiple antenna outputs, the other not...and so on. One has a condenser across an output connector, the other not. If it has an XM entry, you would have to find it in a menu. So BIOS and firmwares are different also. So now I have 2 non-working units.
I will attach some pictures to judge the disaster for yourselfs.
The 4308 CI came with the remotes, microphone, antennas, and I can probably reduce the damage selling those on ebay or selling the whole unit AS IS.
Unit doesn't have any outside or inside damage, except that it's stuck in standby. I performed multiples hard resets without any visible effect. I am more than sure the initial owner did the same. Unit is out of warranty, of course. I wish the idiots from Denon to have a DUAL BIOS, like computer motherboards, to b able to recover from a failed update.
Now what I would like to know...can these boards be reflashed or something or the only way to make it work is to buy a whole new board?
