How to unlock bootloader for SFP GPON-ONU-34-20BI?

For Developers
1

My SFP module is broken. I wanted to unlock the bootloader but I tried Emergency bootloader unlock via TTL serial without success.

I think my USB to TTL adapter is not providing enough power. I can't figure out which external power supply would be suitable. What should I order?

SFP socket should be fine?

How your question relates to openwrt.org software?

None. But if I can't repair my SFP module, then I'll stop all development related to OpenWrt. I'm not going to invest in something that doesn't benefit me. I have other projects on the side and I don't intend to tread water.

It appears you are using firmware that is not from the official OpenWrt project.

When using forks/offshoots/vendor-specific builds that are "based on OpenWrt", there may be many differences compared to the official versions (hosted by OpenWrt.org). Some of these customizations may fundamentally change the way that OpenWrt works. You might need help from people with specific/specialized knowledge about the firmware you are using, so it is possible that advice you get here may not be useful.

You may find that the best options are:

  1. Install an official version of OpenWrt, if your device is supported (see https://firmware-selector.openwrt.org).
  2. Ask for help from the maintainer(s) or user community of the specific firmware that you are using.
  3. Provide the source code for the firmware so that users on this forum can understand how your firmware works (OpenWrt forum users are volunteers, so somebody might look at the code if they have time and are interested in your issue).

If you believe that this specific issue is common to generic/official OpenWrt and/or the maintainers of your build have indicated as such, please feel free to clarify.

I don't know what's gotten into you, but that's not a solution at all.

You really need to explain to me how moderation works on this forum. I am asking a question that some people know the answer to. The thread Support MA5671A SFP GPON remained open for four years. Mine was closed in two minutes.
