What is ECID?




ECID stands for Exclusive Chip Identifier. It is a unique code that identifies the chip inside your device. No two ECIDs are alike. The ECID is not the same as the UDID, which stands for Unique Device Identifier. The UDID is a longer code that identifies your device as a whole.


The ECID is useful for some advanced purposes, such as firmware downgrades, SHSH blobs, or signing status apps. These are methods that allow you to install or restore a different version of iOS on your device than the one that Apple currently supports. For example, if you want to downgrade from iOS 15 to iOS 14, you may need to use your ECID to do so.


How to find ECID on your device?




You can find your ECID in several places, including Settings, on the physical device, in the Finder or iTunes, and on the original packaging. Here are some ways to find your ECID:


  • Go to Settings > General and tap About. Look for the serial number. You might need to scroll down to find the IMEI/MEID and ICCID. To copy this information into Apple registration or support forms, touch and hold the number to copy.



  • If your iPhone has a SIM tray and you need support but can't view the Settings menu, you can use the IMEI/MEID instead of the serial number. On some devices, you can find the serial number in Settings and the IMEI/MEID on the SIM tray or on the back of the device.



  • Connect your device to your computer. On a Mac with macOS Catalina 10.15 or later, open the Finder. On a Mac with macOS Mojave or earlier, or on a PC, open iTunes. Locate your device and click on it. In the Finder, make sure you're under the General tab. In iTunes, click the Summary tab to see its information. For iPhone, click Phone Number under your device name or the device model to find the IMEI/MEID and ICCID. For an iPad (cellular model), click Serial Number to find the CDN, IMEI/MEID, and ICCID. If you'd like to paste this information into Apple registration or support forms, choose Edit > Copy Serial Number.



  • If you don't have your device with you, there are some other places to check that might show the serial or IMEI/MEID number. For example, go to appleid.apple.com in a web browser and sign in with the Apple ID that you use on your device. Choose the Devices section and select your device to see the serial and IMEI/MEID number.



What can you do with ECID?




As we mentioned earlier, ECID is useful for some advanced purposes that involve installing or restoring a different version of iOS on your device than the one that Apple currently supports. This can be done for various reasons, such as performance improvement, compatibility issues, or personal preference.


However, these methods are not officially supported by Apple and may void your warranty or cause problems with your device. Therefore, we do not recommend doing them unless you know what you are doing and are willing to take the risks.


Some of these methods include:


  • Firmware downgrades: This is when you install an older version of iOS on your device than the one that Apple currently supports. For example, if you want to downgrade from iOS 15 to iOS 14, you may need to use your ECID to do so.



  • SHSH blobs: These are digital signatures that Apple uses to verify that your device is running an approved version of iOS. When Apple stops signing a certain version of iOS, you can no longer install or restore it on your device unless you have saved its SHSH blob beforehand using your ECID.



  • Signing status apps: These are apps that allow you to check whether Apple is still signing a certain version of iOS or not. For example, MobileTSS is an app that lets you check the signing status of any iOS firmware using your ECID.



Conclusion




In this article, we have explained what ECID is, how to find it on your device, and what you can do with it. We hope this article has been helpful and informative for you.

How to check iPhone status with ECID?




One of the reasons why you may want to check your iPhone status with ECID is to see if your device is eligible for warranty or repair service from Apple. You can do this by entering your ECID on Apple's website and see if your device has a valid purchase date and coverage status.


To check your iPhone status with ECID, follow these steps:


  • Go to https://checkcoverage.apple.com/ in a web browser.



  • Enter your ECID in the serial number field and click Continue.



  • You will see your device information and coverage status on the next page.



If your device has a valid purchase date and is within the warranty period, you will see a green check mark next to "Your product is covered". If your device is out of warranty or has no purchase date, you will see a red exclamation mark next to "Your product is not covered".


You can also see other details about your device, such as the model, color, capacity, and activation lock status. You can also request a repair service or contact Apple support from this page.


How to use ECID for firmware downgrades?




Another reason why you may want to use your ECID is to perform firmware downgrades on your device. Firmware downgrades are when you install an older version of iOS on your device than the one that Apple currently supports. For example, if you want to downgrade from iOS 15 to iOS 14, you may need to use your ECID to do so.


Firmware downgrades are not officially supported by Apple and may void your warranty or cause problems with your device. Therefore, we do not recommend doing them unless you know what you are doing and are willing to take the risks.


Some of the methods that involve using ECID for firmware downgrades include:


  • SHSH blobs: These are digital signatures that Apple uses to verify that your device is running an approved version of iOS. When Apple stops signing a certain version of iOS, you can no longer install or restore it on your device unless you have saved its SHSH blob beforehand using your ECID.



  • Futurerestore: This is a tool that allows you to restore your device to any iOS firmware that you have saved SHSH blobs for using your ECID. You will also need a compatible SEP (Secure Enclave Processor) firmware and baseband firmware for this method.



  • OdysseusOTA: This is a tool that allows you to downgrade certain devices from iOS 9.x or 10.x to iOS 8.4.1 or 6.1.3 without SHSH blobs using your ECID. This method only works for devices with an A5 chip, such as iPhone 4s, iPad 2, iPad mini 1, and iPod touch 5.

In this article, we have explained what ECID is, how to find it on your device, how to check iPhone status with ECID, and how to use ECID for firmware downgrades. We hope this article has been helpful and informative for you.

How to use ECID for SHSH blobs?




SHSH blobs are digital signatures that Apple uses to verify that your device is running an approved version of iOS. When Apple stops signing a certain version of iOS, you can no longer install or restore it on your device unless you have saved its SHSH blob beforehand using your ECID.


To use ECID for SHSH blobs, you need to use a tool that can save and restore SHSH blobs for your device. One of the most popular tools for this purpose is TSS Saver, which is a web-based service that lets you save and download SHSH blobs using your ECID.

  • Click on Submit and wait for the confirmation message.



  • You will see a link to your SHSH blobs folder on the next page. Click on it to view and download your SHSH blobs for different iOS versions.



To restore SHSH blobs on your device, you need to use another tool that can perform futurerestore, which is a process that allows you to restore your device to any iOS firmware that you have saved SHSH blobs for using your ECID. One of the most popular tools for this purpose is FutureRestore GUI, which is a graphical user interface for futurerestore.


To use FutureRestore GUI, follow these steps:
