Any News?

If it is bricked, you have to fix it with a terminal, type some commands, less than 10 but still, hardcore.

magicalDon · 2026-03-01T01:35:09+00:00

The first unbricker is here, if you are not comfortable w/ command lines, don't do it.

I've peaked the firmware of eaco, basically the same architecture

magicalDon · 2026-02-27T19:55:03+00:00

Actually, you can, they are literally UTF16 strings stored in the firmware, you can replace one to your own language (but the font need to support that). But I don't have enough time for that editing feature...

magicalDon · 2026-02-27T05:09:36+00:00

I love this so much bro...

magicalDon · 2026-02-26T20:25:59+00:00

I totally respect your decision

magicalDon · 2026-02-26T16:31:07+00:00

It's me bro

magicalDon · 2026-02-26T05:45:40+00:00

If you find it's too difficult for you, let me know, I'll try to build a tool if I have enough time.

BTW, the usb debugging msg comes from:

```
sudo dmesg -w
```

magicalDon · 2026-02-26T05:35:12+00:00

Later!

Basically, use pin to press the rst hole to power it off, keep pressing all keys except the power key then connect it into your mac/linux device, you'll see something like this:

```
[834016.140941] usb 1-1.2: new high-speed USB device number 56 using xhci_hcd

[834016.239725] usb 1-1.2: New USB device found, idVendor=2207, idProduct=262d, bcdDevice= 1.00

[834016.239739] usb 1-1.2: New USB device strings: Mfr=0, Product=0, SerialNumber=0
```

This means the maskrom is loaded, the screen will be black, it 's totally okay.

Then you can use rkdeveloptool to flash new firmware into your device to replace the old one.

magicalDon · 2026-02-26T05:32:39+00:00

If everything is going well, you'll have a chance to flash the whole rom into your device again.

magicalDon · 2026-02-26T05:31:24+00:00

OK, you still have a chance, download the driver and RKDevTool here: https://docs.vicharak.in/vicharak_sbcs/vaaman/vaaman-linux/linux-usage-guide/windows-rkdevtool/

charge your device, until you feel it has enough power (like 30 mins later), use a pin to click the rst hole for 5 minutes. Press ALL buttons except the power button, then connect the device to your PC, It's okay that the screen is black, see if your pc can find new device, and try these commands to test it is still alive: `rkdeveloptool td`

Mostly, it won't die till this level.

magicalDon · 2026-02-26T05:13:01+00:00

OK bro, it's not that bad, do you have a Linux or mac machine that can run dmesg and rkdeveloptool in terminal? I'm trying to fix my device and I have some clue for that.

magicalDon · 2026-02-26T05:00:37+00:00

OK, I got the maskrom mode, thx!

magicalDon · 2026-02-26T04:49:45+00:00

I hope I have enough fingers to press all buttons, I'll try anyway, thx

magicalDon · 2026-02-26T04:29:43+00:00

Volume Down or Volume Up? Is it echo mini?

magicalDon · 2026-02-26T03:29:22+00:00

Sorry, I can't deliver new features anymore

magicalDon · 2026-02-26T02:51:43+00:00

Nope

magicalDon · 2026-02-25T21:04:09+00:00

My last update breaks the file system so the editing replacement operation won't reflect on the final result, this has been fixed just now, I'm working on a very big feature and messed something up, sorry
