iPhone 6s iCloud Bypass Unlock Tool Without Change Serial Number By Unlock Tool iOS 15.8.4
⚠️ IMPORTANT DISCLAIMER – READ THIS FIRST
Before we begin, let’s be completely clear.
The iPhone 6s (A9 chip) is vulnerable to the checkm8 bootrom exploit – an unpatchable hardware-level vulnerability that affects all devices with A5 through A11 chips. This means the iPhone 6s is one of the easiest iPhones to bypass iCloud on.
Here’s the good news:
Yes – you CAN bypass iCloud on iPhone 6s running iOS 15.8.4 WITHOUT changing the serial number. Multiple free and paid tools support this exact combination.
However, there are important limitations you need to know:
| Limitation | Detail |
|---|---|
| Signal | On many free bypass tools, cellular services (calls, SMS, mobile data) do not work after bypass – WiFi only |
| Permanence | Some bypasses are tethered – the lock may return after a restart |
| Jailbreak Required | Most tools require jailbreaking the device first via checkra1n or palera1n |
| Legality | Only use this on devices you legally own |
EFT Pro Dongle specifically confirms support for iPhone 6s / 6s Plus up to iOS 15.8.4.
📱 Why iPhone 6s on iOS 15.8.4 Is Bypass-Friendly
| Factor | Why It Matters |
|---|---|
| A9 Chip | Vulnerable to checkm8 – Apple cannot patch this with a software update |
| iOS 15.8.4 | Fully supported by multiple bypass tools |
| No Serial Change Needed | Modern tools bypass without modifying hardware identifiers |
| Mature Tool Ecosystem | Years of development have created reliable solutions |
The iPhone 6s represents the perfect storm for iCloud bypass: an older, well-understood chip with an unpatchable exploit, running an iOS version that’s fully supported by the tool ecosystem.

| 1 | Connect your device to your computer via USB |
| 2 | Press and hold the Power button for 3 seconds |
| 3 | Continue holding Power and press and hold the Home button for 10 seconds |

🚨 Red Flags – How to Spot a Scam
| Red Flag | What It Means |
|---|---|
| Requires changing serial number | Unnecessary for modern tools – often a scam or outdated method |
| “100% success rate on all devices” | Impossible – every device is different |
| “Free tool” but asks for payment | It’s not actually free |
| Requires completing a survey | They make money from your clicks, not from the tool |
| Asks for your Apple ID password | Phishing scam – never share your credentials |
| Unverified EXE or DMG download | Likely malware or virus |
| Claims to restore cellular signal on free tools | Fake – most free bypasses are WiFi-only |
⚖️ Legal and Safety Considerations
-
✅ You can legally bypass iCloud if you own the device
-
⚠️ If the device belongs to someone else, you need permission – bypassing without authorization may be illegal
-
⚠️ Jailbreaking voids your Apple warranty (though the iPhone 6s is likely out of warranty anyway)
-
⚠️ Always use tools from trusted, verified sources – preferably open-source from GitHub
Official Statement from Lockra1n Developer:
“Lockra1n IS NOT for unlocking stolen devices. I am not promoting any type unethical hacking and/or unlocking of stolen devices. By using this software, you are agreeing to these terms.”
