If you encounter a certificate problem, you can use the following two methods to solve it:
1. Reinstall on the computer side.
Take the game on AISI Assistant as an example. After the above problems occur, you can connect the iPhone to AISI Assistant on your computer and reinstall the corresponding games and applications.
If it is an installation package in ipa format, can it be used? Cydia impactor is installed by itself.
2. Use plug-ins? Renewed resupply.
This method is limited to devices that have escaped from prison. Add source code to Cydia after jailbreak? Repo.incendo.ws, and then search for installing plug-ins to reconfigure.
After the installation is completed, open "ReProvision" on the desktop and enter the Apple ID account for automatic re-signing.
The Apple ID account used for signing cannot turn on two-step verification, but the turned-on Apple ID cannot turn off two-step verification. In this case, you can log in to the Apple ID on the computer browser, and then select "Generate Password" under "Security -App Special Password" in turn, and a set of passwords in the format of "xxxx-xxxx-xxxx" will be generated. Just copy this password into the reconfigured password input box.
If there is still a problem with the account, it is recommended to register a new Apple ID without opening the two-step verification login. Re-sign
After logging in, click the software, game icon or "sign in" button, and the application details will pop up. Click the "Sign" button to sign manually.
After signing, open iPhone Settings, find the newly signed application in General-Profile and Device Management, and then select Trust. Go back to the desktop, reopen the application, and you can use it normally.
