All Ive tried is flashing it with the two firmware’s you have posted. Both times it says it had the most recent already. Is there a separate file I should be flashing with? Your pic looks identical to mine.
Well, it’s beyond me. You may be stuck with a 410-flashed 550 unless someone joins up that knows the secret…
If you don’t care about bricking your radio, you could try playing around with the settings in DTR Flash.cfg. If you brave, maybe changing enable_smart_flashing=1 to enable_smart_flashing=0
Again, just shooting in the dark. Don’t try anything if you don’t want to risk bricking your radio.
Sir, I have just read your posts. As an outsider looking in, I suspect that you actually have, for all practical purposes, a Motorola DTR410 in a DTR550 case. This may have been a mistake from the factory, or someone who has moved the board from a destroyed 410 and placed it into an inoperative DTR550 case that was still in pretty good shape. I cannot imagine someone doing this, but if your CPS is reading the radio as a 410, I seriously doubt it is a simple flashing issue. I am not an expert here, but fairly knowledgeable with electronics. I also cannot imagine Motorola making two different board for these units, however, there probably is a reason beside the removable antenna that the 410 is less expensive than the 550/650’s. If I am thinking right the 410 also does not have the capability of private channels like the 550/650’s. Did you purchase this radio new or used?
I felt brave, so tried some settings changes in DTR Flash.cfg. Nothing I tried allowed me to flash my 550 with the 410 firmware. There’s something in the firmware file that has to match to the hardware. If someone were so inclined, maybe decompiling the firmware file and changing it’s header to match the hardware would work, but that sounds like way too much work!
I just went through some used radios I bought off of eBay and found that three of the DTR550s have this problem too. It’s killing me because we use a lot of private groups, so these radios aren’t going to be much use to us. Any chance anyone has found a work-around with it yet? Please let me know if there’s anything I can do to help. I don’t mind having some of these radios be guinea pigs with the possible risk of bricking.
