To replace Thingsboard logo, you will need to build Thingsboard from source code. The logo is defined in : thingsboard-src/ui/src/svg/logo_title_white.svg You will need to replace this logo with your logo, but still using the same file name. Pay attention to the size (width and length) of original logo file, make sure your own logo has the same size. My approach is to generate a PNG logo, with size similar to the original Thingsboard Logo. And then I use Inkscape(https://inkscape.org/) to convert the PNG file to SVG. IMPORTANT : You have to remove the XML Tag in the SVG file you have just generated using Inkscape. Use text editor [ vim or nano] to delete the first line of the SVG file. Now, you need to build or compile Thingsboard source code. Make sure the source code is clean. [ sudo git clean -fdx]. And build!

There can be 2 issues:

Either your SVG is not proper. This happened with me. I created a custom SVG using Inkscape, and it was not backwards compatible with SVG v1.1. You can read more about this issue on this question here. You're not clearing out the old build files. When building the project afresh with new SVG files, first clear out the old files. This can be done easily using this git command: git clean -fdx

Try this web: https://www.aconvert.com/image/png-to-svg/ to convert your png to svg. And download svg file, and place it to folder in ui/src/svg of thingsboard.

And then change the top of the file with this, i give attachment of picture to change it. Especially change the svg id.
