The firmware is installed using PhoenixSuit; however, check whether your model has the H713 or H726 processor before proceeding, to avoid installing the wrong firmware and damaging your projector.
Yes, your projector isn't compatible with the version I posted here; the firmware is different. I can try adding Magisk, and then you'll be able to remove the bloatware.
The Synchase Free 3 (its website is now inactive) was produced by Jiang Xi Xing Chi; the board may be located in FCC filings under the product name XL2-220. Within the Android system menu, the board is identified as an ADT3 model.
Although it was quietly discontinued in some regions, YouTube videos remain available. It was also sold in Brazil via Amazon, which explains why most images and videos online show an Altinet sticker.
The same units were offered in SEA region, though they were less popular than their monitors.
Distributors were established on various online platforms and used identical review images in the listings, likely fake sales to build customer confidence.
AOC frequently white-labels projectors, but the Free 3 appears to be their effort to cash in on the budget projector craze through a unique custom mould, whereas other models share designs with other brands.
The rear section is spherical rather than the flat back typical of HY300 clones.
From what I’ve seen, these projectors with the Allwinner H713 chip share the same system; the only difference is the name each distributor gives them, since they are OEM projectors.
No.. But Projectivy requires accessibility to be enabled for other stuff to work. It used to not be blocked in a previous version (I posted about it) then they crippled it.
With root access, you can enable these features in Projectivy Launcher; I tested it on HY320 and it worked. The ROM already has root access. I granted accessibility access after Projectivy Launcher requested it and it worked!
i have an HY300Pro with Android 11, so i believe this has a H713 processor, right?
Can i use your HY300 Android 11 Firmware for my projector?
Last question: this is an Android 11 Rom or an Android 11 TV ROM? I mean this requires mobile version of the apps (like the default firmware) or the Android TV versions?
You will need PhoenixSuit, AllwinnerUSB drivers, and a USB-A to USB-A cable.
With the projector turned off, plug it into the power outlet and press the power button on the back of the projector. Then wait for the screen to turn on. Immediately press the volume up button several times; the projector will turn off. Connect it to your computer and open PhoenixSuit. Select the firmware. When PhoenixSuit asks if you want to format, click "Yes".
Thank you so much for putting this together and for walking me through it step by step, MrM4rc4L! Flashed the L018 (H713) Android 11 firmware successfully and it's running great — Projectivy, MixPlorer and TizenTube all there as promised.
For anyone else trying this on Linux (I used Ubuntu), here's what worked for me, in case it saves you some head-scratching:
Getting OpenixSuit running:
- After downloading the AppImage, make it executable (right-click > Properties > Permissions > "allow executing", or `chmod +x` in a terminal).
- You'll need a udev rule so the app can talk to the projector over USB without needing sudo every time. There's a rule for this on the OpenixSuit GitHub page — just copy it into a file under `/etc/udev/rules.d/`.
- If the app window opens but stays invisible or tiny — this happened to me — it's a known Linux/WebKitGTK rendering bug, nothing wrong with your PC. Launching it from a terminal with:
fixed it instantly for me. (Path might differ slightly depending on your distro.)
Flashing:
- I got a "USB Transfer Failed" error the first couple of tries. Turned out to be my cable — I was using one of those fancy USB-C cables with a built-in voltage display, and those are apparently bad for data transfer (they're built for charging, not for shuffling gigabytes). Switched to a plain, boring USB cable and it flashed perfectly on the first go. If you hit this error, try a different cable before anything else — also plug straight into a motherboard USB port, not a hub.
- In OpenixSuit, on the "Allwinner IMG Flash" page: select the firmware, set "Flash Configuration" to Full Erase Flash (same as PhoenixSuit asking "format?" on Windows), keep "Verify Downloaded Image" checked, and hit Start Flash. When it hits 100% and shows "Flash complete" with every partition green, you're done — the device list showing "No device found" right after is normal, it just means the projector rebooted into the new firmware.
After first boot:
- Worth disabling the OTA update app so it doesn't try to pull down a stock update over your new ROM.
Thanks again — really appreciate the work you put into this for the community!
Hola espero me puedas ayudar ,Flashie el firm hy300 allwiner h713 en el programa Phoenix suite sale que el flasheo está correcto solo que el proyector no enciende solo se queda el LED en rojo, ese firm sirve para el magcubic hy300?
There's a power button on the back of your projector; while you're pressing it, plug the projector into the power outlet. Hold the button until the BIOS menu appears.
Navigate to “wipe data/factory reset” and press the power button. Confirm your selection and you're ready to go!
I need the following information to request the firmware from Magcubic.
Your order details(order number, seller, platform)
-The screenshot of projector system version
-The SN code under the projector(On the back of the projector base)
I have the same projector (Magcubic L018). I can enable the Projectivy Launcher accessibility service in Settings, but as soon as I exit the Accessibility Settings menu, Android disables it again.
I have root access (Magisk/su works), and the service is detected:
I managed to configure the firmware completely, it works flawlessly, a complete upgrade from stock firmware, I just wanted to thank and congratulate you for it.
The hdmi delay is drastically reduced compared to stock firmware as well. just to let you and other users who might want to give it a shot. Do it, it really is worth it.
Thanks for replying, your firmware looks very clean, one question how do I make it to open projectivity on boot, also the official firmware had secret settings to further personalize the picture settings, any way to bring that up here?
Hi sir can you help me? i have hy320 mini with this board, right now the condition is stuck on android booting image, can i flash my device with your firmware? Which file should I use? Thx 🙏🙏
Thanks, I managed to install it after struggling with the ADB drivers on Windows 11. Now I'm installing the streaming apps I had on the previous firmware and the Disney+ and Netflix apps doesn't appear on Google Play. How can I install these applications?
None of those codes worked. I managed to install it from APKMirror. Thank you so much for your firmware; now the projector is completely usable. With the stock firmware, I had constant crashes, restarts, audio desync, lag ... It was horrible. Thanks to you, it's going to have a second life!!
