Many users have ever experienced that after jailbreak white icons appear on the springboard instead of the usual icon. To solve this problem we have two options that we detail below.
The first solution is to download the tweak from Cydia iWipeCache and then run the application. This application will clear the cache on your iPhone and allow the icons to reappear normally.
La second option go through installing the utility in Cydia Springtomize 2. Once you have downloaded Springtomize 2, run it, activate and deactivate it using the "enabled" switch and then click on the "Reload" button.
We will get a warning that will ask us what action we want to perform, to which we have to respond by clicking on the "Reload Settings" button. If it has not been clear to you how this process is carried out, after the jump you will find a video in which the steps to follow are perfectly detailed.
As you can see, the solution to the problem of white icons after jailbreaking our iPhone or iPad is very simple.
