Shsh2 blobs can be a confusing topic for many Apple users, especially when it comes to understanding whether they are specific to each phone. Let's break it down in a more straightforward way to help you grasp this concept better.
Shsh2 blobs, also known as ECID SHSH blobs, play a crucial role in the process of upgrading or downgrading iOS firmware on your device. Essentially, these blobs are unique pieces of data that are used to authenticate the firmware installed on your iPhone, iPad, or iPod touch with Apple's servers.
Now, when it comes to the question of whether Shsh2 blobs are specific to each phone, the answer is yes, they are unique to each device. Why is that important? Well, since these blobs are device-specific, you cannot use Shsh2 blobs from one iPhone to restore or upgrade another iPhone.
Each device has its own unique identifier, known as ECID (Exclusive Chip ID), that is used to generate these SHSH blobs. This means that the SHSH blobs stored for one device cannot be applied to a different device. So, if you're thinking about sharing or using SHSH blobs from another device, it won't work due to this unique identifier.
To make things even clearer, SHSH blobs are specific to each device and are necessary for restoring or upgrading your device to a particular iOS version. These blobs are generated and saved during specific firmware versions while Apple is still signing them. Without these SHSH blobs, downgrading to an older iOS version becomes tricky, as Apple stops signing older firmware versions once a newer version is released.
In conclusion, if you're looking to preserve your ability to downgrade or upgrade your iOS firmware to specific versions in the future, it's essential to save your SHSH blobs for your own device. Remember, these blobs are unique to each device and cannot be used interchangeably between different Apple devices.
So, in summary, SHSH2 blobs are indeed specific to each phone, and they play a vital role in the iOS firmware downgrade or upgrade process for your Apple device. Make sure to save your SHSH blobs to maintain control over your device's firmware versions in the future.
