Here’s a tutorial that how you can check the ECID number of iPhone, iPad, iPod in just a few steps.
How to Find ECID Number of iPhone,iPad:
What Is ECID Number?
ECID stands for Electronic Chip ID, which is a unique number assigned to every device that Apple manufactures.
Apple uses this number to ensure each SHSH Blob (an SHSH blob is a term for a small piece of data that is part of Apple’s digital signature protocol for iOS restores and updates, designed to control the iOS versions that users can install on their iOS devices (iPhones, iPads, iPod touches, and Apple TVs) ) remains limited to a specific device only. This is the reason why you can’t use SHSH Blobs from any other user for restore and downgrade purposes.
All popular SHSH tools require you to enter your ECID number. Hence, knowing this number is a prerequisite for saving your SHSH Blobs.
Here’s a step by step tutorial on how to find your ECID number with or without a computer.
iTunes with Computer
This is the conventional method that everyone can use to find their device’s ECID number. This method will display this number in hexadecimal format, which is what we want to input in an SHSH saver tool.
Here’s what you need to do:
Step 1 Connect your device to your computer.
Step 2 Open iTunes.
Step 3 Click the device icon to open the device summary page.
Step 4 Click the Serial number field twice.
Step 5 iTunes will now display the ECID of your iOS device
UDID Calculator (WITHOUT COMPUTER)
UDID Calculator is a Cydia tweak that displays your ECID number, UDID number, and a whole of other relevant information about your device. Tweak developer Malcolm Hall develops it.
This is by far the best method to get hold of your ECID number. With this method, you need not to have access to a computer or iTunes. However, it does come with a catch – you must have a jailbreak running on your device to use this.
Step 1 Open Cydia.
Step 2 Go to the Search tab.
Step 3 Perform a search for UDID and tap the very first result that comes up on the list.
Step 4 Install it, and it will appear on your home screen once the installation process is over.
Step 5 Start the UDID Calc app and copy your ECID number. Remember, this number is in Decimal format.
That’s all there’s to it! You can now go and start saving your SHSH Blobs.
There are a couple of other methods as well, but they are too complicated for the average user. Therefore, I always stick to plans that are easy to use and understand.
