The delivered license is registered with the respective e-mail address and valid for future versions of XperiFIX. This means that users do not have to pay for each update. After payment, the download link will be sent. The license is created and activated after your payment. You will receive the license details with your purchase receipt. Please note that due to the license agreement a refund is excluded! Please make sure your device is compatible before you buy. I am not responsible for errors in TWRP or Magisk and do not support it via ticket. Please also note that you pay for the software and license, not for the support! Support is a free service to users, but not a requirement.
Users of the XperiFIX software can always download and install the latest version. Please check the following KB article to get more informations about updating XperiFIX to the latest version: Knowledge Base -> Update XperiFIX
