The jailbreak for iOS 10 has been long overdue. It was released last month for all 64-bit devices up to iOS 10.2. As you know, the main reason why a lot of users jailbreak is AppSync.
AppSync is a tool available on Cydia that allows you to install unsigned IPA files. AppSync was developed primarily for testing purposes. It was a geared towards developers only. However, tons of users use this powerful tool for pirating paid apps.
As always, a lot of users began asking about it on Twitter. Luca got so tired of hecklers on Twitter, he ended up blocking a lot of them.
It is not compatible with iOS 10 jailbreak and causes your device to bootloop. Even after repeated warnings, some users still installed Appsync.
I will block anyone mentioning 10.2.1, AppSync, Cydia issues, iPhone 7. And those who are unable to mention me without reply all too.

Lesson learned: you can give them jailbreaks but if AppSync doesn’t work they’re still mad.

iOS 10 devices got stuck in a bootloop as AppSync crashes installd whenever Cydia runs uicache. Before we begin, we will use a network analyzer and SSH client to uninstall this malicious tweak. Here’s how to fix this problem.
How to Remove/Uninstall Appsync Unified without losing Jailbreak/Tweaks/Data on iOS 10
Step 1 Download Fing network analyzer on another device. Fire it up.
Step 2 Perform a network scan.
Step 3 Find the name of the device on which Appsync is installed and find its IP address.
Step 4 Download iTerminal SSH client. Remember, if you have jailbroken your device with the latest beta versions of yalu102, connect through USB only and not with Wi-fi.
Step 5 Create a new connection with the following details –
IP/HOST – IP address of the iOS device you located in step 3
USERNAME – root
PASSWORD – alpine
Step 6 Connect.
Step 7 Execute the following commands given below –
apt-get –purge remove net.angelxwind.appsyncunified
killall -9 SpringBoard
That’s all there’s to it. You have successfully uninstalled and removed Appsync unified without losing your jailbreak, tweaks and data.
If for some reason, this fix doesn’t work for you, follow the tutorials given below.
Step 1 Connect your iPhone/iPad/iPod to your computer with USB.
Step 2 Start Yalu and jailbreak your device. If you don’t know how to do this, follow this tutorial. Before you proceed, make sure your device is in jailbreak state.
Step 3 Fire up any SSH client such as Putty.
Step 4 Connect to your iOS device using the details given below –
USERNAME – root
PASSWORD – alpine
Step 5 Enter the command dpkg -l. This will display a list of tweaks installed on your device.
Step 6 Enter the command dpkg -r AppSync. This will delete AppSync from your device.
Step 7 Enter the command now – killall -HUP SpringBoard. This command will respring your iOS device.
Step 8 Enter the command – su -c uicache mobile.
Step 9 Type su root and then reboot your device by entering the command reboot.
Hopefully this will fix your issue completely. Even if this fix doesn’t work for you, follow fix number 3.

- Go to Find my iPhone.
- Access the map and it will show your iPhone/iPad/iPod.
- Click on your device and select the restore button.
- Select the Restore button and enter your Apple ID and other credentials that Apple requires.

Yalu jailbreak for iOS 10, 10.1.1 and 10.2 firmware still remains in beta. Many users may encounter bugs due to this. A stable jailbreak is just hours away as mixtape player still remains to be added.
Mixtape player is delayed due to bonus track still being worked on, preventing a final yalu102 release.
