all the goods from taiHENKaku. No need for switchKaku or the unofficial taiHEN offlineInstaller.
The goal of this guide is to walk you through updating to the latest R7 HENkaku
and updating your R6 offlineInstaller to R7 as well. Hitting two birds with one stone.
INSTALLATION & UPDATE PROCESS
• Run the R6 Offline Installer (via email)
• Launch the offlineInstaller bubble on your LiveArea
• Press X to Install, Wait for it
• Close it, once it is done
• Restart your PSV
• Run the R6 Offline Installer (via email)
• You will notice it will synchronize to go.henkaku.xyz updating to R7
• You will notice that there is something "different"
• Check Settings > System > System Info
(It should show some chinese characters with "3.60)(-7" )
Congratulations, you're now on HENkaku R7!
plus your OfflineInstaller have been updated to R7 as well

Side Note: I did not install the taiHEN BETA on my PS Vita nor have I installed switchkaku
or the temporary taiHEN offlineinstaller. I waited for the official integration.
What if I'm currently on taiHEN beta?
