Where to download Vuforia 6.2.6?

Since Vuforia 6.2.10 is broken (see https://developer.vuforia.com/forum/device-support/samsung-galaxy-s5-mini-not-working-vuforia-6210) where can I download a version of Vuforia that actually works?

Alternatively, when can we expect an update that will make Vuforia usable again?

Note that I can not just ignore the affected devices. Our app needs to work on those devices too, and in fact it *did* work on those devices, prior to the current version of Vuforia. Please allow us to simply re-download that previous version of Vuforia, while you are working on a more permanent fix for whatever problem is causing this issue.
