Hi,

I downloaded the firmware and upgrade soft from this page:

https://drive.google.com/drive/folders/1MI5XiLReotmvD9N0kJKL_q--yb3REeFH

However, during upgrade, I received several errors:

2022-07-20 16:12:38 Application Startup...

2022-07-20 16:12:51 DEVICE1:206 (2M) (2M) CLEAR_VDFS_FAILED("None" in fwsp.BaseFirmwareOP.ERASE_FLASH(fwsp.py, line 685))

2022-07-20 16:12:52 Device 1:206 failed: (2M) CLEAR_VDFS_FAILED, took 1 seconds (35%)

2022-07-20 16:13:39 DEVICE1:206 (2M) (2M) CLEAR_VDFS_FAILED("None" in fwsp.BaseFirmwareOP.ERASE_FLASH(fwsp.py, line 685))

2022-07-20 16:13:39 Device 1:206 failed: (2M) CLEAR_VDFS_FAILED, took 1 seconds (35%)

2022-07-20 16:14:13 DEVICE1:206 (2M) CLEAR_BOOT_FAILED

2022-07-20 16:14:13 Device 1:206 failed: (2M) CLEAR_BOOT_FAILED, took 1 seconds (35%)

Now, it will not even turn on. It is always found by the firmware upgrade tool, but the firmware never once was successful in completion. The reboot and reset is not doing anything to help revert the situation.

Can you at least provide me with original firmware that the speaker was sent with, so I can try reverting to it? If not, are there any other ways? The instruction is only written with succesful ugprade in mind, no instructions for the failure. 

Best regards,

x.

Hi friend,

 

Thanks for choosing EarFun. Sorry to hear that.

 

We kindly suggest you try another device and USB cable to upgrade the firmware.

 

Update Notes:

1. Please fully charge the speaker first. (If the speaker is not fully charged and plugged into the laptop, insufficient power supply will cause the update to fail.)

2. Find a USB-C cable with data channel. (Kindly note that the original USB cable doesn't work.)

3. Place the speaker on the desktop, do not move the speaker or the cable.

4. If the update is unsuccessful, please try again a few times. 

 

If the upgrade still fails, please email to our customer service team via service@myearfun.com and we will provide you with the original firmware to try.

 

Sincerely,

 

EarFun Customer Service Team

Hi,

Sorry, nothing worked, it seems bricked.

Sorry,
