This uses the checkm8 bootrom exploit, which works on all 32-bit devices (including iPhone 4s). This method requires technical skill.
Hardware needed:
Process (Simplified):
Pros: Bypasses completely (sometimes allows SIM functionality). Cons: Tethered (you must repeat the process every reboot). High risk of bricking if done incorrectly.

For years, the most reliable way to bypass iCloud on the iPhone 4s was using a specialized hardware chip, often called a "R-SIM" or an "Interposer."
How it works: You place a thin circuit board chip underneath your SIM card. This chip tricks the iPhone's baseband into thinking it is activated on a carrier network.
Pros:
Cons:
Most bypass tools and methods rely on manipulating the device's connection to Apple's servers. The iPhone 4s on 9.3.6 sits in a unique position:
Specifically, iOS 9.3.6 was a tether update. This means that unlike later iPhones, the 4s still uses a ramdisk-based activation system, making it vulnerable to DNS or hosts file redirects and activation record swapping.
Yes! An iCloud-bypassed iPhone 4s on 9.3.6 is a perfect candidate for Phoenix or Home Depot jailbreaks. A jailbreak allows you to install a tweak like iCl0udBypasser to hide the setup app permanently. However, a jailbreak also makes the device less stable.
Technically, you can bypass the iCloud lock on an iPhone 4s running iOS 9.3.6. However, you cannot fully unlock it like a new phone. Because the iPhone 4s is an A5 chip device with checkm8 bootrom vulnerabilities, it is susceptible to certain exploits. But there is a catch: Signal and cellular functions are impossible to restore permanently on a bypassed 4s. This uses the checkm8 bootrom exploit, which works
For a more stable bypass that allows you to install apps via iTunes (sideloading), you need a computer. The gold standard tool for 32-bit devices is Sliver by the development team at r/Jailbreak.
