Miracast HDMI dongle with All winner A10 - Android Stick & Console AllWinner based Computers

I have bought a dongle and discovered it does not have the usual RK SoC , instead it has an Allwinner A10. The pcb is red, it has the SoC, flash, sram, some voltage regulators and a push button and a led. Does anyone have any idea where to get firmware roms for this dongle? The stock firmware is very bad. Dlna barely works. Miracast disconnects immediately after connection.

@an31415 people would need the name and model number to stand a chance of helping you.
I think the best you could hope for is firmware from another identical device sold under a different brand name.
if you were able to try this you'd still need to have the original firmware on hand in case it didn't work.

Thanks @3mel for your reply. The product box says "HDMI Dongle Wifi Display Receiver" and on the dongle it is written "Anycast". This is one of the many clones you can by on Aliepxress. I was hoping it's one with an RK cpu, but after cracking it open I found out it has an Allwinner A10 cpu. I searched high and low on internet to find and alternative firmware for it because the current one is crap. I'll try to attach some pictures here of the PCB, maybe somebody can identify it and point me in the right direction.
But how do I attach picture? Can junior members do it ?

More info: the dongle PCB is red and has a label, SP-X11-V2.0, and the name of the Wifi access point it creates is SP-xxxxxx, where the Xs are random hex digits.
The Wifi addon pcb is green and has no markings. The wifi chip is a well known Realtek that is found in all other similar products.

if you inbox me the AliExpress link I will post it here for you, that's probably the best way for anyone to identify it.

I received the variant in the colorful box(not the blue ones) and it does not say M2 nor M4 on the box. The product description says it has an AM8252 cpu, but it's not true. I guess the only way to id it is to post pictures of the pcb.

the chips aren't the same as yours but does the board look similar ?
being honest I wouldn't get your hopes up, it's a cheap clone / copy of a chromecast. it's not going to be supported that well, they've already sold you something that doesn't match their product description. take it for what it is and learn that you get what you pay for... sorry.

The board is not similar, it has different ICs, different layout, different color. But the plastic enclosure is identical, except for the venting holes on the back, which are bigger on mine. This case copies the Chromecast (first generation), so people expect it to be a Chromecast clone. It isn't, but it does serve a similar purpose
The date on the PCB is 2019.10.10, fairly recent. I expect a new wave of clones have hit the market, disguised as already established products, but based on a different SoC. The only problem is their firmware is even less stable than the old ones, so I guess other people, not just me, are looking for solutions.

---

some of those people looking need to be devs.

Yup. Or anybody with a similar but not identical A10 based board. Maybe we can spot different fw versions in the wild

A small update if anybody is interested. I've connected the board via usb to my laptop (running linux mint). Doing this while keeping the button pressed will put the board's bootloader in some sort of firmware update mode. Running lsusb will show it as an usb device : "Bus 001 Device 066: ID 1f3a:efe8 Onda (unverified) V972 tablet in flashing mode". Of course this is not an Onda tablet, but it certainly has an identical SoC, thus the misidentification of the usb device.
Googling for this string I randomly found out there are some people called the sunxi community that strive to create a linux kernel and toolchain for these Allwinner devices, and they have done it quite successfully.
There are many custom firmwares for tablets, tv boxes and mini PCs that are based on the allwinner SoC. It seems this miracast hdmi device is just a trimmed down mini PC. It certainly runs pure linux, no Android, because its ram and flash are much smaller than what I found in the specs of any android devices.
So the question is: does any body have any knowledge of the existence of such a linux based firmware for this miracast board ? I'll go ask the sunxi people also.
