Incorrect firmware updated EBang

[mniknezhadi]

Dear expert,
I did wrong model firmware update to EBang "E9.3" . I did update E9.3 by E9.i firmware.
I try frequently to update the miner to it's firmware(E9.3) but any changes happens.
Please help me to fix it.

Thanks in advance.

Have you tried to reset it to factory default? You can find it on the maintenance tab.

Also, check the front of the miner if it has a reset button. As I can see there are two holes on the front check them the one button must be a reset button.
If one of them is a reset button try to hold and press the reset button for 15 seconds and then wait a couple of minutes.
After that, flash the firmware back to EBIT 9.3 firmware(Make sure it's the latest version) then test it again.

This should be the right firmware "E9.3  Firmware version number: Firmware – V9.0.0.23.tar"

ِDear BitMaxz,
Thank you for your replay.
I did not only reset it to factory (from maintenance menu) but also by pushing the reset button. I can change it's firmware version to any version of E9.I'S but not to E9.3 (as you append it) .

Well, if it doesn't work I think there's no solution yet that can solve this issue. When searching about ebang machines related to your issue the same issue as yours I can't find that they solve or revert back their firmware to original firmware.

What I think is try contacting ebang support and maybe they can help to solve your issue.

You can contact them with their skype.

The only thing that I notice about the firmware of E9.i and E9.3 is they have different firmware extensions.

E9.3 extension is .bin and the E9.i is tar.gz. So I think you can bring it back to E9.3 if you can find a firmware with tar.gz extension.
Here check this one I found my old download history of this firmware
- http://miner.ebang.com.cn/upload/miner/cms/btc_upgrade_9.0.0.20.tar.gz

It might be a 2019 firmware as the download date. The name is "E9.3 Firmware version number: Firmware –9.0.0.20" so this is the right firmware.

I hope it will work if not better try to contact them.

ِDear BitMaxz,
Thank you for your direction,
I did try to update it to recent firmware (btc_upgrade_9.0.0.23.bin). I'll try to update the device by the firmware as you send the link one (btc_upgrade_9.0.0.20.tar.gz).

Dear BitMaxz,
I updated the out of ordered E9.3 by "btc_upgrade _9.0.0.20.tar.gz" and the problem is fixed.
Thank you for your direction.
