Re: LG Xboom PK5 demo mode..probably

How do you flash the firmware?

Nice work tomodachi!
Good to see more useful things getting saved from the dump. Proof that manufacturers don't give half a sh** about the environment and only care to fill up their pockets.

Also, thank you for sharing the firmware here. I'm sure other people will find it useful as more of these demo units are uncovered.

Re: LG Xboom PK5 demo mode..probably

I also purchased 2 demo units of PK3 but haven't figured out a way to turn demo mode off.
PK3 has a different motherboard design inside. PK5 and PK7 have 64 bit SPI rom chip inside but PK3 don't.
would be good to use them if possible

Re: LG Xboom PK5 demo mode..probably

I work for a major retailer which has the demo units for the PK7, PK5, and PK3. If you look at the bottom of the unit you will see SVC CODE: PK3.AUSDEMO

These are firmware modified units from LG which will disables all controls other than "Enhanced Bass", prohibits Bluetooth, and battery operation. I the only way I have seen people overcome these firmware locks in the past is to open a retail unit, dump the firmware, open the demo unit and overwrite the NAND with retail firmware.

Now you may convert them to retail version if you have any, see my retail version firmware dump above

Re: LG Xboom PK5 demo mode..probably

Any suggestion. I have a pk7 with the same problem.

my dump from PK5 works fine with PK7 as well, you can reflash your firmware chip without any doubt.

Hey, I m here again with the solution !
Finally found a retail version of PK5 and backed up firmware from it.
did exactly as rcdavi3 mentioned here and result was just as expected.
after reflash unit will work same as retail version.
I m posting here the dump, its ok but belong to an older version.
after reflash unit will work same as its retail version.
Remember to update firmware after reflash, not only will update software, it will also increase volume to about %20
To update firmware you need to install an app to your phone named "LG Xboom"
any questions let me know

Models that work with this dump;
LG Xboom PK5
LG Xboom PK7

So I guess that means we need someone who has a dump of the retail firmware to post it here.

What a waste! I'm sure LG could have easily programmed the Demo mode inside as an additional option. So frustrating to see manufacturers do things like this.

haha thanks, I m also a hardware guy myself but gadgets nowadays piss me off with their strange firmware issues

Any suggestion. I have a pk7 with the same problem.

Re: LG Xboom PK5 demo mode..probably

Would be interesting to see if that indeed solves the issue.

Hoping that someone sees this and can get a firmware dump here.

When it comes to firmware, I usually throw in the towel - but that's just me: I prefer to stick to hardware issues only.

Re: LG Xboom PK5 demo mode..probably

Any chance to find firmware binary file I can reflash ? any suggestions ? I can reflash the firmware to its motherboard.

Re: LG Xboom PK5 demo mode..probably

Update :
I discovered that speaker s charging circuit working, on mobile application you can see current capacity, now its %100 percent full, but still don't allow me to use it, it turns itself off when turned on. But when connect charger it turns on its own

Re: LG Xboom PK5 demo mode..probably

It's possible.
But it wouldn't make sense to hardwire anything. After all, why do that, when you can just take any production floor model, and program a Demo mode to activate by pressing some buttons in a certain sequence or by selecting from a menu. This is what many other modern electronics (like TVs, for example) do, so I don't see why they would try to hardwire anything.

So true

"Not for sales" might be they are broken waiting to be fixed .

I don't think so, the person I got them from said he has loads of these and they all have same issue, said he bought them from a bankrupted company

Re: LG Xboom PK5 demo mode..probably

This speaker can't be hardwired to work as a demo right ?

Re: LG Xboom PK5 demo mode..probably

if you have the app https://play.google.com/store/apps/d...xboom&hl=en_GB
im sure if you go into settings there is a update section maybe this will update the firmware?

thanks for the suggestion, I did it but still not fixed, maybe I should find a good one and copy the firmware and flash it to mine
