Apple blocked Cydia Impactor, yet Saurik was able to bypass it and release an update. However, users are now facing another error called “progress.hpp:87 ” while signing IPA files.   What does “progress.hpp:87” error signify?   Signing issues with Cydia Impactor continue to plague users with no end in sight. After yesterday’s “maxQuantity error” fiasco, users are now reporting another weird error with the latest update (0.9.44). The progress.hpp:87 error doesn’t relate to anything whatsoever and the short error message doesn’t help things either. Here’s what this error message looks like. progress.hpp:87
_assert(false) According to me, it indicates an issue with the pre-existing certificates on your device. Once you revoke them, you can start signing IPA files without errors or glitches. However, the latest version of Cydia Impactor doesn’t revoke certificates properly. To fix this issue, you can grab the older version and then use it for certificate revocation.   Fixing progress.hpp:87 error in Cydia Impactor Step 1 Download the older version of Cydia Impactor (0.9.43) . Step 2 Extract its contents to any location on your computer and launch it. I recommend transferring its contents to a folder on your desktop for quick access later. Step 3 Connect your iOS device to your computer and ensure the tool recognizes it. Step 4 Click on XCode and then press the Revoke Certificates button. Step 5 Go back to the latest version of Impactor (0.9.44) and sideload the required IPA file with it. This fix works works on all devices and firmware versions. If you are still facing issues while signing, just leave a comment below. Hopefully, Saurik will release an update that will fix the broken “revoke certificates” option. Saurik is currently down with fever and, hence, this update could take a while before we get our hands on it.   Cydia Impactor (0.9.43) Download Link: https://ioswar.com/775aca0194e5c7c4/Impactor_0.9.43.zip
