I’ve just pushed the latest TinyUmbrella BETA. This version fetches the current SHSH from the device. This means that if you are running 8.1.2, it doesn’t matter if Apple is no longer signing 8.1.2, TinyUmbrella will fetch the SHSH from the device.
There are a couple of conditions:
● You must be jailbroken
● You must have AFC2 installed (Search Apple File Conduit “2” in Cydia)
● You must have an A7 or A8 device. This will not work for anything lower.
A7 Devices include:
● iPhone 5S
● iPad Air
● iPad Mini 2 (retina)
● iPad Mini 3
A8 Devices include:
● iPhone 6
● iPhone 6 plus
● iPad Air 2
If you do not have one of the above devices, semaphore says you will need to wait for an iFaith update from iH8sn0w.
Currently, saving your SHSH blobs is still "useless", but semaphore, says "I would not have updated TU if there wasn’t at least a moderately good reason to. So, no it is not useless to save them." He also revealed that he is working with iH8Sn0w on "an awesome exploit he discovered".
