Panasonic UB820 Blu-ray Player Multi Region Hack - Full guide!!

Watch how to install the Rattlebyte Multi-region chip into a Panasonic UB820 4k Blu-ray Player to enable all regions of blu-ray and DVD discs to be played. I couldn't find any clear videos on exactly what's involved for the UB820 so I hope this helps anyone that's looking for information or just some reassurance on the process!
I'm very satisfied with the end result and get to watch all of my multi-region collection.

I bought my Rattlebyte chip directly from their website:

Panasonic UB9000 clone remote control I bought:

Panasonic UB820 4k Blu-ray Player:

If you're not comfortable with soldering, take a look at some modified players instead, which I've linked below:

Could have been far better .. You spent more time picking the out of focus shots + loud music than showing the important info on the disassembly and chip fitment

Red (3.3V), Green (B), Blue (A), Black (GND), Orange (C), Brown (D) if you have the same cable harness. You can cut/isolate the rest of the wires, so that not to touch each other or other parts of the player.

This is very well put together video and as far as I can tell the only one online relating to this mod, however, I really wish more time had been taken to show the disassemble of the unit (tricky getting the cover off) and the full modding process in more detail instead of quick sharp cuts. Hopefully I can find more detailed information elsewhere as the instructions that come with it are pretty barebones as well.

Edit: finally got the cover off without breaking it which I thought I was going to and after looking in more detail at your video and pausing it at certain shots I was confused about which wires on the open ended cable harness as they didn't seem to match with the lettering on the mod itself. I went on the rattlebyte website and clicked on the cable harness page and was able to see which wires specifically were correct - that's something that should be in the instructions really. Anyway, I'm not good at soldering but it's only 6 points and after a little trial and error everything seemed connected OK. The firmware updated and it's working so I guess as long as I don't touch it everything will be fine!

Very useful mod that is cheaper than buying a region free player.
I have been soldering all my life so fitting the kit will not be an issue.

During the 2000's, I first started collecting DVD's that are multi region. Later in the 2010's, I started collecting muli region Blu-rays along with a multi region Blu-ray player. Later in the late 2010's, I got into 4K which later got me buying an LG UBK-90 4K player that's multi region.

I feel like you missed highlighting one of the most important features, and I would have liked to see a review of using it.

The ability to load Subtitles from USB to use with a Blu-ray, so that you can play foreign movies and add English subtitles even if they're not included on the disc. My player does work with the "Magic button combo" so, the ability to load external subs really is the only thing I'd buy this for.

I've never soldered before, should I try to attempt this?

At 2:31, that little green board/chip with the qr code, is that the wifi chip? In between the steel/metal sheet? The one where it gets a close up at 2:34 on the upper left, where it has a wire coming out of it.

Great video! Am I correct in assuming that the rattlebytes harness-B set won’t work with the 820 because there’s no harness near the soldering points to plug into? That is, we only have the option to solder….? Thanks!

[Kilo]

Thank you. I ordered a player and the rattlebyte kit.

The last part of the mod is disconnecting your doorbell!

[Cinefilo_Celuloide]

Wow, what a good job you've done, but it would have been better if you had done the work from start to finish for those of us who don't have the knowledge but your video is very good thank you

[gordonleslie]

With my Panasonic UB820 I prefer to press the down button then the back button twice....works every time and easier.

[cindydavis]

there's only one Red wire for the 3V#, but two spots to solder it to?

[HomeCinemaEnthusiast]

Nice hack, I’ve just got the last Pioneer 4k player 👌👌👌👌👌

[christianevans]

Are you able to perform normal Firmware updates now?
Great video thanks

[viktorderka]

this FW applies to Panasonic 9000 too?

[Theninjagecko]

I'm confused as the official listing for this player states Plays Blu-ray Discs Zones A B & C
Plays DVDs from regions 1-8

[xJI]

Is this the same mod that’s been done to the region free units for sale ?

[Pidalin]

The fact that regioblockations still exist is shocking, EU and other big countries or unions should finally ban it, that's the only solution, they will never stop with that if we don't force them.
A lot of shows were never in my country, for example Walking Dead on blu-ray is mostly import in English only, how can I know what region it is? I am not sherlock holmes.
