If your iPhone is stuck on the iCloud Activation Lock screen, you’re not alone. Millions of users face this problem every year — whether from buying a second-hand device, forgetting an Apple ID, or inheriting a locked phone with no way to reach the original owner.
The most effective technical solution available in 2026 is using iOS Ramdisk Boot Files. These are low-level firmware images that allow your computer to boot the iPhone into a custom RAM environment, completely bypassing the iCloud activation screen — without touching the system partition. In this guide, you’ll learn exactly what boot files are, which devices are supported, how the process works, and where to download the files for free.
What Are iOS Boot Files / Ramdisks?
iOS Ramdisk boot files are specialized firmware images that get temporarily loaded into the iPhone’s RAM during startup. Unlike a normal boot, the device never reaches the iCloud Activation Lock screen because the operating system loads from a custom environment instead of internal storage. This method is powered by checkm8, a permanent bootrom exploit that affects all Apple devices with A5 through A11 chips. Because the exploit lives in the hardware bootrom, it cannot be patched by Apple through software updates — making this one of the most reliable unlock methods available. Tools like palera1n, checkra1n, and custom Python-based loaders use these boot files to access the device filesystem, remove the activation lock flag, and allow the iPhone to be set up fresh.
Compatible iPhone Models (2026)
The Ramdisk boot method works on iPhones powered by Apple A9 through A11 chips. Here is the full compatibility list:
| Device | Chip | iOS Support | Compatible |
|---|---|---|---|
| iPhone 6s / 6s Plus | A9 | iOS 12 – 16.x | ✔ Yes |
| iPhone SE (1st Gen) | A9 | iOS 12 – 15.x | ✔ Yes |
| iPhone 7 / 7 Plus | A10 | iOS 12 – 16.x | ✔ Yes |
| iPhone 8 / 8 Plus | A11 | iOS 12 – 16.7.x | ✔ Yes |
| iPhone X | A11 | iOS 12 – 16.7.x | ✔ Yes |
| iPhone 11 / Pro | A13 | Partial | ⚠ Limited |
| iPhone 12 and newer | A14+ | — | ✗ Not Supported |
Important: This method uses the checkm8 bootrom exploit and only works on devices with A5–A11 chips. iPhone 12 and later are not supported. Always ensure you legally own the device before proceeding.
What’s Inside the Boot Files Download Package?
The Ramdisk folder is organized by iOS version and device model so you can find exactly what you need. The package includes:
- Ramdisk boot images for iOS 12 through iOS 16.7.x
- Compatible firmware files for A9, A10, and A11 chips
- A Python-based boot loader script (cross-platform: Windows, macOS, Linux)
- SSH enabler for advanced filesystem access
- A detailed README file inside each version folder
Everything is hosted on MediaFire and is completely free to download.

Step-by-Step: How to Use the Boot Files
Once you have downloaded the Ramdisk folder, follow these steps carefully:
- Install dependencies — You need Python 3, libusb, and usbmuxd installed on your computer. On Windows, also install the Apple Mobile Device USB driver.
- Extract the folder — Unzip the downloaded archive and open the folder matching your iOS version and device model.
- Put your iPhone in DFU Mode — Hold the Volume Down button and the Side button together for 8 seconds. Then release the Side button only, keeping Volume Down held for another 5 seconds. The screen should go completely black.
- Connect via USB — Plug your iPhone into your computer. Open a terminal inside the extracted folder.
- Run the boot script — Type
python3 boot.pyand press Enter. The tool will auto-detect your device model and iOS version. - Wait for the ramdisk to load — Your iPhone will boot into the custom ramdisk environment. This typically takes 20–40 seconds.
- Remove the activation lock — Use the included bypass tool or SSH into the device to delete the activation lock record. Your iPhone can now be set up normally.
Tip: If your device is not detected in DFU mode, try a different USB cable (preferably an original Apple cable) and a direct USB port — avoid USB hubs.
Frequently Asked Questions
Is this method safe for my iPhone?
Yes. The ramdisk method does not modify the iPhone’s system partition. It runs entirely in RAM and leaves no permanent changes after a regular reboot.
Will this work on iOS 17 or iOS 18?
Currently this method supports up to iOS 16.7.x on A11 chips. iOS 17 and 18 are not supported as Apple has added mitigations in newer versions.
Do I need a computer?
Yes. A Windows, macOS, or Linux computer is required to load the ramdisk via USB. There is no phone-only method for this process.
Is this legal to use?
Bypassing the activation lock on a device you legally own is permitted. Using this method on a stolen device is illegal. Always have proof of ownership before proceeding.
What if the device is not recognized?
Make sure the iPhone is in proper DFU mode (not Recovery Mode), the Apple USB driver is installed on Windows, and you are using a direct USB port. Try a different cable if needed.
Does this permanently remove the iCloud account?
The ramdisk bypass disables the activation lock check but does not remove the Apple ID from Apple’s servers. The device functions normally but iCloud services may be limited if the original account is not removed by its owner.
Final Thoughts
The iOS Ramdisk Boot Files method remains one of the most reliable and free ways to unlock iCloud Activation Lock in 2026 — specifically for iPhones running on A9 through A11 chips. While it requires a computer and a few technical steps, the process is well-documented and widely used by the iPhone repair and reseller community. Download the files using the button above, follow the steps carefully, and your device should be accessible within minutes.
Always use this method responsibly and only on devices you legally own.
