If you are getting this error it is more likely from the signing service. It is missing the entitlement in their IPA. You will have to delete Electra app then install VFS exploit from cool stars website. Then install using Cydia Impactor until the signing services fix the multi path version. I’ve tried all 3 signing services so far and all failed with exploit error.
Just went through this process myself. Uninstalled NudeKeys last night in favor of Bloard which seems more consistent and cleaner with iOS’ UI in my opinion. I left the tweak enabled and removed it via Cydia like I always have. Today I realized each system app basically had some form of a past NudeKeys setup even though the tweak was gone. I had to reinstall it, disable it through its settings, then remove it again via Cydia.Just a heads up!
I have multiple devices, so I just save them as “iphoneecid”, “ipadecid”, “iphoneimei”, “iphonemodel” and descriptive names that the keyboard just replaces for the actual number. It saves you a lot of time.Just remember to change them if you get a newer device.
If you hold on to the "Rotation Lock" button, your screen will automatically rotate to landscape or vice versa! I never knew this and just found this out just a few minutes ago. It's a pretty nifty feature.
Go to coolstar.org/electra in safari, click “download” and then click “more” and “copy to ext3nder”. Install it, remove autosign on your old version, and reboot.
