Here’s how to make AltStore runs on iOS 15 & iPadOS 15

As of when this article is written, iOS 15 is still in public beta mode, it has not been released to the masses, but that doesn’t stop you from getting and installing iOS 15 legally and ahead of pretty much everyone else.

Check out this complete guide here how you can install iOS 15 & iPadOS 15: I’m updating my iPhone to iOS 15 today and here’s how you can update yours too (iPad and iPod Touch included!) at JILAXZONE.


Option 1: Direct from iOS device.

You can use Option 1 if you are still on iOS 14 or iPadOS 14. In case you have updated to iOS 15 / iPadOS 15, proceed to Option 2 instead.

a) On your iOS device, open AltStore. Go to “My Apps” tab. See if you can see the “Update” button. Tap on the “Update” button to update AltStore. Before tapping on “Update”, ensure AltServer is running on your Computer and your iOS device is connected to your Computer.

If AltStore update is available, you’ll see it on this screen.

b) Once update is completed and while your iOS device is still connected to your Computer and AltServer is still running, do either “Refresh” your existing sideloaded apps or sideload a new app. If they are working, then you are good to go. AltStore is now working on your iOS device running iOS 15. If not working, proceed to Option 2.


Option 2: Reinstall AltStore from Computer

Do this if Option 1 is not working for you or if you are already on iOS 15 & iPadOS 15.

1) Run AltServer on Computer. If you don’t have AltServer running on your computer, follow this guide to get it installed: detailed guide to install AltServer and AltStore at JILAXZONE.

2) Install update or Check for updates. You’ll be prompted to update AltServer, however in case you don’t get the prompt, do click on the AltServer on Windows taskbar, choose “Check for updates…”, follow the instruction if the AltServer installed on your computer needs updates (installation wizard will prompt you the instructions, follow them to get latest AltServer installed on your computer).

3) Install AltStore on your iOS device. Do it, even if you have AltStore running on your iOS device. Click on the AltServer, choose “Install AltStore”, ensure your iOS device is not turned off while installing, otherwise the installation may fail. Key-in your Apple ID and password when requested. Once install completed, you’ll get a pop-up telling, AltStore installation is done.

4) Refresh app or sideload a new app. Once latest AltStore installled on your iOS device, you can either refresh the existing sideloaded apps or sideload a new app. If everything is working, then you are good to go.

Fix AltStore Error: Failed to perform authentication handshake with server by re-installing AltStore

If you get failed handshake to the server, that means your AltStore installed on your iOS device is not the latest one. Redo either option 1 or 2 above to ensure you are using the latest AltStore.


During Refresh, loading bar stuck and never complete

When trying to refresh existing sideloaded app(s), the loading bar started to move, but it is never finished even after 5-10 minutes waiting, then what you can do is this:

1) First kill AltStore, and re-open.

2) Once re-opened, navigate to “My Apps” tab.

3) Under My Apps tab, select the app you want to refresh, then long tap on the app, it will pop you up the sub menu. Tap on “Deactivate”.

4) Once deactivated, then select the app again, long tap to show the sub menu, tap on “Activate”.

Try accessing the app to see if it’s now working as expected. In case deactivating then re-activating the app is still not working for you, then try to delete the app from the iOS Home Screen, then redo installing the app. Step by step sideloading app, you can find it here: detailed guide to install AltServer and AltStore at JILAXZONE.
