LinageOS on Samsgung Galaxy S5e WiFi from scratch from Linux with heimdall

Compile a patched version of heimdall

Install dependencies required to build heimdall (https://github.com/Benjamin-Dobell/Heimdall/blob/master/.github/workflows/build.yml#L14)
Now clone and compile heimdall with the patch from Benjamin-Dobell/Heimdall#478

cd /tmp
git clone https://github.com/Benjamin-Dobell/Heimdall.git

Ensure that mailu runs on mysql as DB for easier SQL migrations
Create temporary tables with the correct structure for mailu (remove where filter like domain_id=4 or email like "%@mydomain.com" to dump all domains)

CREATE TABLE mailu_domain
select
    cast(now() as date) as created_at,
    null as updated_at,
    'ispconfig_import' as comment,
    domain as name,
