1. Login to Your shopify store. Go to Online Stores > Themes
2. Click on the three dots next to the theme you want and then click Duplicate.

Open theme files editor

1. Click on the three dots next to the theme copy and then click Edit code.

2. Don't close open editor. Next step describes how to fill changes.

Make changes according to instructions

Go to the theme package folder. Open updates/manual folder.

"Let's say the latest version is 1.0.3 and your current one is 1.0.0, and you want to update to the latest version, 1.0.3."

This means that you must consistently follow instructions one update after another in a strict order:

1. theme-update-from-1.0.0-to-1.0.1.zip
2. theme-update-from-1.0.1-to-1.0.2.zip
3. theme-update-from-1.0.2-to-1.0.3.zip

Consider an example of how to make instructions in the first step, theme-update-from-1.0.0-to-1.0.1.zip:

Double click on file theme-update-from-1.0.0-to-1.0.1.zip > Double click on nested file theme-update-from-1.0.0-to-1.0.1.html

1. Replace libraries

The first step in the instruction is to replace the static libraries that are not edited by hand, but simply overwritten for convenience. Libraries are complex minified files that, in any case, cannot be edited manually and the difference in changes between versions of libraries cannot be tracked.

This means that, for example, you must replace the first library in the assets/bundle-head.css file with a fresh version.

To do this, go to the theme file editor that we've opened in this step. as was described in Updates / Open theme files editor.

Next, unzip the theme archive upload-me-to-shopify-platform-lumia-1.0.3.zip that is downloaded locally.

Next, Click Add a new asset

And upload the fresh library assets/bundle-head.css to the server from the unzipped theme upload-me-to-shopify-platform-lumia-1.0.3.zip

Thus, you need to replace all the libraries that are mentioned in the first paragraph of the instruction.

2. Make changes line by line

The second step in the instructions is to replace strings in different files. In the tables it is shown on the left as it is now on the server (-) / on the right it is shown as it should be (+). You need to delete what is on the left and do what is on the right.

Consider the example of changes in the first file in the second paragraph of the instruction.

Go to the online theme editor, look for the file config/settings_schema.json and replace
"theme_version": "1.0.0" with "theme_version": "1.0.1"

Click Save.

You must go through all the instructions in all files specified for manual modification.

"If your theme version is too old, you'll likely need to make multiple updates. Make all updates one by one in a cycle as mentioned in the order in third step Make changes according to instructions . However, if you've already uploaded everything from the latest version, you won't need to upload the libraries again.
