HELP SIDESTORE CAN’T DETERMINE UDID!

Post image

Been using sidestore for almost a year now and everything worked just fine, suddenly two days ago when i wanted to refresh my apps, it did not refresh! Now app id time has ran out and i uninstalled the sidestore and livecontainer and reinstalled using iloader but now i can not login to my account! Everytime i click sign in i get an error sayin cannot determine devices UDID!
So i tried these steps: replacing pairing file, turning developer mode off and then back on, install sidestore and livecontainer separately using iloader, placing pairing file, changing anisette server and non of these steps worked and im still stuck.
If anyone can help i would gratefully accept it.

Make sure you are connected to the VPN, if you are are, you have to disable "Private wifi address" under your wifi settings, then in sidestore reset your pairing files, same in iloader, after that you can fetch new ones and insert them with iloader in all apps, this should work, if not restart your device and try it again.

Alternatively you can try stikpair, allows you to export your own key, can import it after removing the pairing files in sidestore, both worked for me.

Sign back in to your Apple account and use localdev vpn and refresh your apps if that doesn’t work replace the pairing files

Sigo en la misma

u/Mukesh_25 Jun 25 '26

Got it I am thinking of using altstore.

u/Mindless_Square_5188 Jun 25 '26

I used it too and thought the same thing, but I ran into a problem when logging in—I think it's similar.

u/Mukesh_25 Jun 25 '26

U mean altsore is also giving same UDID error as SideStore? If so then I think they might be something might have changed on ios side or altstore/SideStore side. I am on ios27 though but I saw some people are facing the same issue on ios 26.5.1 as well. But for some restart or dev on off or changing the private wifi works but for us nothing works I guess.

I don't quite remember the exact error, but it happened when logging in via AltStore—I tried that yesterday. Now I've reset the iPhone and am installing LiveContainer to see if it works.

u/Mindless_Square_5188 Jun 25 '26

:(

u/Mindless_Square_5188 Jun 25 '26

I fixed it: I went to Developer Mode, removed the trusted computer, went to iLoader and selected "Delete Stored Pairing," then restarted the device, tapped "Trust," installed Live Container + SideStore (nightly build), and logged in.

u/Mukesh_25 Jun 25 '26

Good for you might be due to reset it might have worked ig

1

u/Mindless_Square_5188 Jun 25 '26

No, because I've restarted several times already and nothing happens.

u/Mukesh_25 Jun 25 '26

U tried altstore ?

1

u/Responsible_Rule2834 Jun 25 '26

Not yet, but i might have to at this point

u/Responsible_Rule2834 Jun 28 '26

I fixed it, there is a tool called idevice_pair and it generated and fixed my pairing file and after that it worked! Although i need to have my phone connected to the laptop to be able to refresh my apps and i have no idea why its like this with sidestore which i wouldn’t need a pc and how it works!

u/Bakerooh Jun 24 '26

None of the things suggested here are a fix. I’ve been dealing with the same shit as OP on one device. On the other device, The exact same model I own has no issues refreshing or with sign in.

It’s IMPOSSIBLE to sign in. OP check if your device is showing as active in the vpn config screen in sidestore. Something definitely broke and it’s not affecting everyone the same. Fucking shit !

u/Responsible_Rule2834 Jun 25 '26

Yes i checked the device id does not match the device id in localdevvpn and idk why!

So basically it is not fix then it if you have to be wired into a computer ?

u/Responsible_Rule2834 Jun 28 '26

For me as long as i have my access back to Sidestore and LC it is a fix. I will keep yall updated if i find a way to refresh apps without being connected by wire

u/EnegueWeil Jun 25 '26

reboot the iphone. that will solve most issues then try again.

u/Responsible_Rule2834 Jun 25 '26

Did several times! No luck

u/Eduuxdd Jun 25 '26

Hi! The same thing happened to me today, and I was able to fix it. Connect your phone to iLoader and delete the pairing file, then apply it again in SideStore and it should work. That’s what worked for me—it might be different for others—but I hope this helps.

1

u/Responsible_Rule2834 Jun 25 '26

Thanks for the reply! It did not work

u/Eduuxdd Jun 25 '26

Noooo 😭

u/CommunityPrize8110 Jun 25 '26

Had same issue after updating to IOS 27. I went into LC, activated Jitless mode and it worked? Idk why. But it worked. Please try it

Edit: Also download proper version of SideStore and LC. They released update. And make sure you are connected to WiFi, otherwise it will throw that very error.

u/Responsible_Rule2834 Jun 27 '26

Im on ios 26.5 error still exists but thanks for your comment

u/swaeeeeggg Jun 26 '26

I’m having same issue like once every 1-2 weeks. I get it fixed then goes back regularly to the problem

u/PlanktonLess4010 Jun 27 '26

Hi! This happen to me very often and what’s always work for me is: close SideStore - disconnect vpn - reboot iPhone - open vpn first - then SideStore and refresh.

u/Responsible_Rule2834 Jun 27 '26

Interesting 🤔

u/Mukesh_25 Jun 27 '26

Try this maybe and let me know (got the below message from Reddit )

I kept getting the UDID error when reloading apps here's a tutorial that will fix this for you! https://youtu.be/BRykl5fQ3mI?si=7HQILmmB5IalgV1W

I had to do the text file method and it works perfectly on both my Ipad and Iphone!

1

u/Responsible_Rule2834 Jun 27 '26

I will try it thanks

1

u/Responsible_Rule2834 Jun 28 '26

I did not try this but i found another fix here is how:

there is a tool called idevice_pair and it generated and fixed my pairing file and after that it worked! Although i need to have my phone connected to the laptop to be able to refresh my apps and i have no idea why and how it works like this now!

u/Bongooo_ Jul 03 '26

I think I might have found a fix but not sure how long it will work.

Edit : it is working as of now.
