First of all one important thing – before you start to do anything with your phone, do the backup of your personal data. It is only for your safety in case that something goes wrong or any mistake happens. In that case you can use the backup to restore the data and try to do everything once again. Each tutorial has been done many times to verify its propriety, so just read carefully all instructions and continue step by step. Our tutorials will be of course updated every time when Sony Mobile publishes anything new, affecting any of our topics. The major part of every file has been created by myself and every file has been tested on the corresponding phone. All referenced files are determined for Sony XPERIA 1 J9110. So, what can you expect in terms of mentioned manuals / tutorials?
