BCD436HP/BCD536HP: Older Firmware versions.

[seth21w]

You can try it with the bin file but I don't think it will work. It won't hurt anything it will just be in the firmware folder if it's not right when you unplug it.

The only one that had the correct files was the open uniden site, they were .bat files but someone has removed the only site to get them. Now if you save the files to your computer of the contents of your SD card and then use another SD card you can duplicate the files and have more than 1. I have 2 SD cards, the original 4 gig has the factory firmware mine came with, I took it out of my scanner after I copied it's contents, then used my 16gb card and copied the firmware to it and then downgraded. But that was from the .bat files. I forseen that the site would come down as soon as this upcoming pro voice upgrade was talked about.

They are bin files for the 436 an 536... What you might have seen was for a different radio. .bat is a file that runs (Batch File)... That might of been one of the VUP files... maybe... Cant look at it so don't know...

No the VUP are .msi That's a windows installer package...

But to make it easier to find I will quote it here haha

It is certainly possible to affect reception by firmware. The attenuation status, for example, is driven by programming. As are band filter switching and I'm sure other things. But, none of that would be subtle and all would be noticed by everyone, not just a few.

No way to back up the firmware that is in the scanner. Factory load is bad firmware. You wouldn't be able to program DQKs, for example. Many other changes made to add and improve features.

He stated no way to back up the firmware.

I was not aware that backup meant downgrade or roll back. I will have to update my dictionary. :lol:

The site openuniden.com is not a genuine Uniden site. as seen here and here.

Yeah you mentioned that before... I know it is (was) not an official site... But the files I did grab from there I ran a program called "Windiff" to compare them with the ones I pulled from the scanner before I cycled it. They were identical...

I never stated anything other than the fact the site was not owned or ran by Uniden

Also the open uniden site may not have been official but it had every scanner model uniden makes and the firmwares they used from the very beginning on up to the very latest. I wonder who owned the site, and why it's been taken down now! That is the real mystery!!! Oh and the firmwares were legit! Not made up. I know as I am sitting here listening on the 1.02.03 firmware that came from that site, and my scanner is brand new and came preloaded with 1.05.01. Which sucked.

You could ask this person who seems to be the one running the site as seen here

I also never said the firmwares were not legit. I do see below that Randy compare some 1.05 and they were different...

I did a compare of the 1.05 with the 1.05 I have for the 436... They are different...
I tried the 1.02.03 anyway... It won't load... You get a checksum error...

Thanks anyway... It was worth a try...

And that's the reason why I only use the updated firmware that's obtained thru Sentinel..

I never said you did... Just mentioned that you told me before that it's not an official Uniden site...

They were different because one was for the 536 and the other was for the 436... Wanted to see how much different they were.

When I compared one of the 436 files from that site... Ex: the version 1.05.01 for the 436 and the file from the sentinel update (copied from firmware folder before power cycling the scanner) They were identical.

My post in that thread was in a specific context relevant to a specific time. At that time, the only "previous firmware" was the original factory firmware which was bad. In that context, at that time, there was no way to go back as there was no way I was going to put that firmware out for availability.

Now, of course you can, and I would not say the same thing today. It would be pretty stupid for me to say something so blatantly and demonstrably untrue.

But, in the context of the official methods (BC_VUP and Sentinel) it is true there is no way to revert to earlier versions, correct?

That is correct... Unless you have an older version bin file...
That is for the 436/536 cant speak for the other models...

Define bad because I tried all firmware and all seemed to work as far as scanning and decoding. Sure it was missing little features here and there but I wouldn't call them "bad"

openuniden.com is up

 

[Blackswan73]

His site is up, grab em while you can
I got all of them.

 

[Blackswan73]

It is about 500 meg, if anyone decides to download all the firmware files.
