Many advanced modification tools require registration on a dedicated web portal before you attempt an installation. Copy your converted ECID code.
The is a unique hardware identification number for every iOS device. Unlike a Serial Number or IMEI, the ECID is specific to the chip itself. Apple uses this ID to generate "SHSH Blobs," which are digital signatures required to authorize any firmware installation. Why You See "ECID Not Registered"
