OK here's what I know, shsh blobs is coming form apple not from cydia.
It is a unique ID generated by your idevice, and only apple can generate it that's why they can stop the signing of certain firmware or OS.
ECID is like the name of your device in order apple can identify it, and generate it's own unique shsh blob, which in kind will be saved to cydia if in case you want to saved it for future used.
I repeat again even the dev team or notcom who created umbrella cannot generate the special shsh blob of your device and also CYDIA is not a shsh blob generator, it is a server to save your shsh blob.
If you understand this, it is impossible what you are saying, maybe you have saved your shsh blobs before, that is why you can downgrade it back to 4.0.1.
Better delete this thread.CHEEERS |
