Sources checked: 2026-11-13. Tested on a device by staff: not yet. Written from the store's own code and the tools' own pages, not from running it on a phone.

What the Download button does. It sends you to the file address the app's listing provides. The store does not sign the app and does not install it. So "it fails" is one of two different problems: the file did not arrive, or the file arrived and your tool could not sign or install it.

1. The file did not arrive (nothing in Files or Downloads, a blank page, an error page).

• Try again on a different network, or from a desktop browser, and save the file.
• If the link is dead, use "Report a problem" on that app's page and name the app and version. The listing owner has to fix the link.
• The file should end in .ipa. A page asking you to log in, pay, complete surveys or download a "helper" first is not an install file; close it.

2. The file arrived but will not install. The app is an unsigned IPA until a tool signs it with your certificate and installs it. Open it in your sideloading tool (AltStore, SideStore, Sideloadly, LiveContainer) rather than tapping it. Our comparison: https://nabzclan.vip/threads/61/

When your tool shows an error, check in this order:

1. Developer Mode is on (Settings, Privacy & Security). See "Developer Mode and Untrusted Developer".
2. The free-account limits are not used up: 3 apps, 10 App IDs, 7 days. See "Free Apple ID limits".
3. The exact error text. "The provisioning profile is banned" (0xe8008024) has its own article.
4. The tool's status thread says it works today: https://nabzclan.vip/threads/66/ to 70.

Choosing a signer. Third-party signing apps and services exist and members mention several by name. NabzClan does not sell, recommend or vouch for any of them, and staff have not tested them. If one errors, the cause is usually the certificate behind it, not your phone, and only whoever provides that certificate can say whether it was revoked. Do not pay anyone who promises a certificate that "never revokes"; nobody can verify that. If you are unsure, a free Apple ID with one of the four tools above is the option we can source.

Signing errors and apps that stopped opening. Our troubleshooting guide covers what members report, why a signed app can stop opening (expired or revoked certificates), what to include when you ask for help, and what not to do: https://nabzclan.vip/threads/79/

If it still fails, open a ticket under Sideloading and app help and include: your device and iOS version, the tool and its version, the app name and the link you used, the exact error text, and what you already tried. Helpdesk: https://helpdesk.nabzclan.vip

These steps can stop working when Apple or the tools change. The forum threads linked above are kept up to date; check them for the latest.
