Rootless Jailbreak
Rootless Jailbreak introduced a safer method of personalizing iPhones, without deeply modifying the system files.
Today, while Rootless Jailbreak doesn’t support the latest iOS versions, there are modern alternatives like zJailbreak that offer safe, simple customization for newer iOS devices, without complicated processes or risks.
Let’s dive into everything you need to know about Rootless Jailbreak and how you can safely personalize your iPhone today.
1. RootlessJB for iOS 12 – iOS 12.1.2 (by Jake James)
RootlessJB was developed by Jake James specifically for iOS 12 – iOS 12.1.2. It used a kernel exploit to allow userland-level tweaks — meaning you could customize many parts of the iPhone without touching critical system files (root access was not granted).
Key features of RootlessJB (iOS 12 – 12.1.2):
- Based on the voucher_swap exploit.
- Offered non-root jailbreak — tweaks were installed in user-space directories.
- Included Cydia Substrate support (partial) for tweak injection.
- Safer than full jailbreaks because system stability was better preserved.
- Designed mainly for A8–A11 devices (like iPhone 6S to iPhone X).
How it worked:
After jailbreaking, users could install compatible tweaks using SSH or Filza File Manager, but system-critical tweaks (that needed root permissions) would not work.
Limitations:
- Some popular tweaks required root access and would not function properly.
- Manual installation of tweaks was often required.
- No official package manager like Cydia or Sileo was bundled by default.
2. Rootless JB for iOS 11 – iOS 11.3.1 (based on Ian Beer’s empty_list exploit)
The earlier version, Rootless JB for iOS 11 – iOS 11.3.1, was based on Ian Beer’s empty_list exploit.
Key features of Rootless JB (iOS 11 – 11.3.1):
- Used the empty_list exploit, a powerful vulnerability found by Ian Beer (Google Project Zero).
- Provided a “rootless” jailbreak environment — no modification of essential system files.
- Very lightweight and minimalistic compared to full jailbreaks like Electra or unc0ver.
- Targeted mainly at developers and advanced users rather than casual users.
- Did not include a graphical interface initially — most interactions were via SSH.
Rootless Jailbreak Installation Guide
⚠️ RootlessJB is only compatible with specific iOS versions (iOS 11 – iOS 12.1.2).
Here’s how users traditionally installed Rootless Jailbreak:
- Download RootlessJB IPA file (from trusted sources).
- Install RootlessJB using a tool like Cydia Impactor or AltStore.
- Trust the app on your device:
- Go to Settings > General > Device Management and trust the installed profile.
- Go to Settings > General > Device Management and trust the installed profile.
- Open RootlessJB and tap “Jailbreak”.
- After successful jailbreak, install tweaks manually using SSH access.
Note: Installing tweaks with Rootless Jailbreak usually required SSH access, and tweaks had to be installed in non-root directories — not as easy as modern jailbreaks.
In Short, Key Differences Between the Two Rootless Jailbreaks
| Feature | Rootless JB for iOS 11 | RootlessJB for iOS 12 |
| Developer | Based on Ian Beer’s exploit | Created by Jake James |
| iOS Support | iOS 11 – iOS 11.3.1 | iOS 12 – iOS 12.1.2 |
| Exploit Used | empty_list exploit | voucher_swap exploit |
| Tweak Installation | Manual, via SSH | Manual, via SSH (slightly easier with partial Substrate support) |
| Cydia / Package Manager | Not included | Not included (but easier to add manually) |
| User-friendliness | Very technical | Slightly easier, but still advanced |
Why Rootless Jailbreak is No Longer the Best Choice
Rootless Jailbreak was a clever solution for older iOS versions, but:
- It’s not compatible with iOS 13, iOS 14, iOS 15, iOS 16, iOS 17, or iOS 18.
- Tweak installation is complicated and requires technical skills.
- Many tweaks today are not designed for rootless environments.
Today, if you want safe, easy, and modern iPhone customization, there are much better options available — especially through zJailbreak.
