This error occurs because the checkm8 bootrom exploit does NOT support the iPhone 7 (iPhone9,x). The exploit works only on A5–A11 devices, but iPhone 7 (A10) is excluded due to Apple’s hardware mitigations.

If it shows 3d101ap – that’s corrupted. Restore device via iTunes/Finder.
If it shows iPhone12,8, then your tool has a bug.
Bottom line:
3d101ap is not a real iPhone 9/SE 2nd gen identifier. Your tool is either:
→ No public loader will work for that string. Check the tool’s source or use a different approach. loader for iphone9 3d101ap not found
The error "Loader for iPhone 9 (3D101AP) not found" typically occurs when specialized software, often used for jailbreaking (like Palera1n) or sideloading, cannot identify the specific hardware or firmware signature of your device.
The identifier 3D101AP refers to a specific hardware revision or board configuration often associated with development or prototype-style builds, rather than standard retail model numbers. Because Apple officially skipped the "iPhone 9" name—moving directly from the iPhone 8 to the iPhone X—this error usually surfaces when using tools designed for older iOS 9 software or "budget" legacy models. Steps to Resolve the "Loader Not Found" Error Verify Device Compatibility
Confirm your actual device model by going to Settings > General > About. If you are using a tool meant for iOS 9 but your device is a newer model (like an iPhone SE 2nd Gen, which was sometimes nicknamed the iPhone 9), the software versions will not match. Update Your Tools
Palera1n / Jailbreak Tools: If the "loader" app is missing after a jailbreak attempt, try using a different version of the software. Some users have found that rolling back to a stable beta (e.g., Palera1n version 2.0.0-beta.4) fixes loading issues for specific board types.
Sideloading Apps: If you are using a computer-based installer like Sideloadly or AltStore, ensure the program is updated to the latest version to support your current iOS firmware. Enable Developer Mode (iOS 16+) This error occurs because the checkm8 bootrom exploit
Newer iOS versions require Developer Mode to be manually toggled on for custom loaders to run.
Go to Settings > Privacy & Security > Developer Mode and toggle it On. If this option is missing, connect your device to a Mac with Xcode open to trigger the menu's appearance. Hardware Connection Check
Errors in finding a "loader" or device signature often stem from poor data transfer.
Use an Apple-certified USB-A or USB-C cable (avoid third-party hubs) and try a different port on your computer. Force Restart
If the device is stuck or the loader fails to appear after a "successful" flash, perform a force restart: quickly press Volume Up, then Volume Down, then hold the Side button until the Apple logo appears. irecovery -q | grep "ProductType"
Are you attempting to jailbreak a specific device or install an .IPA file for a particular app? Knowing your current iOS version will help narrow down the correct loader version. No Developer Mode option on iOS 16 device.
this was the case for me. ... Hello , am facing the same problem , can't find developer mode , using an iPhone 14 pro max , 16.2 , Apple Developer
| Step | Action |
|------|--------|
| 1 | Confirm your device is an iPhone 7 GSM (Model A1660, A1778, A1780). |
| 2 | Update your tool to the latest release (Checkra1n 0.12.4+, palera1n 2.0.0+). |
| 3 | If using ipwnder/gaster, recompile from GitHub. |
| 4 | Manually add the loader from an iOS 15.8.2 IPSW for iPhone 7. |
| 5 | As a last resort, map 3d101ap to 3d100ap in the tool’s source. |
The error message "Loader for iPhone9 3d101ap not found" typically occurs during the iOS firmware restoration or forensic extraction process. It indicates that the software application (usually a specialized tool like checkm8-based utilities, forensic software, or custom IDE tools) lacks the specific binary loader file required to communicate with the device's Secure Rom (ROM) or specific hardware revision.
Without this loader, the host computer cannot send execution commands to the device's processor, rendering the device stuck in DFU (Device Firmware Update) mode or Recovery mode.
This is the most common cause. The specific board ID 3d101ap requires a loader that matches the device's specific Boot ROM revision (likely BOOT or POODLE exploit substrates for A10). If the tool being used is older than the device's iOS version or the specific hardware revision, the required loader file may not exist in the tool's local database.
Ensure you are using the latest version of the software attempting the restore.
