Hi , I hesitate to overload you with more than you already got, but I as well as many others have units that want to upgrade… This one I have seen before in the list so I hope it will work…

@zpl1025 - I missed to address you , but those were naturally to you …
Hi Mats, you’re the very early user of Linkplay 
,
Btw, the first one does not work, it’s different hardware platform. And could give a try to the 2nd one, I’ve deployed and you could test.
And for anyone want to try the latest A31 firmware, could check out this post, and you could upgrade the device manually, which relies on a tool but could try it immediately.
And I don’t need to maintain the server any more
@zpl1025 Oh, my dear friend, I hope you can help me!
I have this speaker set from Power Dynamics, model WCS50.
the UUID starts with FF31F012 and the firmware was very old… I couldn’t goup these speakers with arylic amplifier board (amp_V4).
So, I went to the LinkPlay firmware page and saw that the Rakoit firmware was more recent and had the same UUID start.
I used the Updat tool and updated the Power Dynamics speaker set with that formware but now, I have very loud squeeks/screeches, everytime sound tries to come out of the speakers. I notice that it does that when playing the normal setup messages and even after that (setup process), apart from being able to pair the speaker set with the V4 amp, if I try to play music, it’s screeching loudly again…
I don’t know if you could identify the correct firmware from the brand alone, I saw that before updating manually, the MCU_VER was “6”., and the PROJECT was “MY_WIFI” (I’m only shure about the MY_* part…
I understand if this is not enough info to solve my problem, no worries.
I also tried to contact the brand and see what they say…
Thanks in advance!
which file exactly you’ve upgraded? Normally, upgrade the A31 firmware won’t cause such issue.
And if I understood correct, after upgraded, you could still see WCS50 in APP, but when you try play music or the internal notification sound, it will have very large distortion. And could you still identify the sound playing?
Hi again,
I uploaded “a31imuzobox_rakoit_new_20210929_all_burning”.
It seemed the same product. But I noticed later that it’s not.
The UUID is not the same start.
The sound isn’t recognizeable at all…
Thanks once again.
Solved… Used your repacked firmware: " a31rakoit-4.6.415156-b1-c3bddec5-20240816.zip".
Hi! I guess there’s a very very slim chance that you see this but did you ever find any new firmware for those?
My Audio Pro has the UUID FF280012E2DD12F6F9E9CA8D which I interpret as ours having the same chipset.
Thanks
@zpl1025, Can you please add my device

@zpl1025 Hope you can help me too.
First, I am really positive surprised on the effort you do in helping people with non-arylic devices. This thread is the main reason I have bought Arylic devices, and will stick to those in the future.
But before I knew of this got some madison speakers, with a linkplay module. The firmware is really old, and does not play well with my newer Arylic devices.
They use a Texas TAS5731m DSP talking I2S.

Hi Mao, thanks for the trust. And btw, please check the solution of this topic. You could upgrade the firmware manually.
Hey
First, let me say a big thank you for your work in getting some of these old devices lifted into the future 
I noted the name “Arylic” in my head for future purchases 
I successfully updated two Medion speakers I bought, but am struggling with two others that seem to be running on really ancient firmware - the update tool simply gets stuck on “applying update: 0%”, and uploading the firmware via the Web UI (which worked fine for the two others) returns “”
Any chance these can still be updated, or are they somehow incompatible with the allburning image?

Ah, what I forgot:
I have just picked up a new “old Stock” Muzo Cobblestone. I’ve had one from launch so thought to pick up another for another old Hifi. However the OTA is no longer live and the device is running firmware 3.5.3228 from the box and my other one in my house is using 4.2.7717. The 4.2.7717 works with Spotify but the “new” device running 3.5.xx does not.
I’ve discovered this forum and see there is master file created with a loader. I don’t want to brick this “new” device as it still works with ApplePlay so useful to me. But I would like to use Spotify directly.
Before I run this loader can anyone with MUZO tell me if they have used it and if it was successful how it works for you?
Thanks!!
Hi! First off all: this thread’s amazing. Working against the unnessearay obsolescence of older equipment. So thanks a lot for the great effort!
I do have a Saxx AS50 Speaker that runs on a Linkplay A28 (UUID:FF28F012). I was going through the models at the OTA products.xml. It seems for some of the listed speakers there were actually models that came in both A28 and A31 versions. With both using the same firmware. In this thread someone wrote that they successfully updated a A28 speaker while other posts suggest that the A31 firmware is not compatible with the A28.
Does anyone have experience with the A28? Right now mine runs the 3.5.3613 firmware and I’m trying to get it to one that supports Tidal.
