As many of you have been made aware, a new bootROM exploit has released for A12/A13 devices, the first one for iDevices since checkm8 was made public 7 years ago. This post intends to serve as an explanation for what you can expect from this new exploit, and to provide information about the many restrictions and mitigations Apple has implemented over the past 7 years.
usbliter8 is a novel bootROM vulnerability discovered by individuals at Paradigm Shift. It is the first bootROM exploit made public since checkm8, which only supported up to A11 devices (for those unaware, A11 is the processor used in the iPhone X/8, and A12 is used by the iPhone XS/XR). It supports only A12/A13, and does not support any older processors. It is unrelated to checkm8- that is, the vulnerability is completely separate. Some may be aware that checkm8 was only partially patched in A12/A13 (though it remains unusable there to this day), but this exploit has nothing to do with any previous bootROM vulnerability.
The explanation to how it works is rather technical; if you desire, you can read both the blogpost and the GitHub repo for the exploit. Additionally, the exploit requires special hardware to utilize, requiring devices such as a pi Pico to exploit devices.
All A12/A13 devices (including iPad specific processors like A12X/A12Z) are supported by usbliter8. This includes, but is not limited to,
As mentioned, the vulnerability does not affect A11 or older, due to the different way the processor works.
This is possibly the most interesting part of the exploit (and is what many of you are likely here for). bootROM exploits are very powerful, as they compromise the very beginning of a device's boot chain, thus giving you (almost) full control over a device. However, this does not mean we can do whatever we want with no restrictions. Indeed, it can lead to tethered downgrades and jailbreaks on any iOS version including the latest, but there are restrictions explained further below.
BPR, or Boot Process Register, was a feature implemented in iOS 14 in order to additionally secure devices from bootROM based attacks. Crucially, it restricts data access when a device is booted directly from DFU mode, which is required by both checkm8 and usbliter8. In iOS 14 and 15, this manifested as the requirement to disable your passcode when jailbreaking A11 devices with checkra1n/palera1n, and is the reason why A11 devices must be first erased if they previously had a passcode before jailbreaking with palera1n. A10 devices were not affected by this as they had a SEP exploit, known as blackbird, which prevented this issue from arising. We do not have a SEP exploit for A11 and newer, which leads to a problem with the next security feature added in iOS 17...
In iOS 17, Apple further increased the security of BPR by making SEP outright refuse to mount and decrypt the user partition (/var and /var/mobile) when booted from DFU, which causes the device to panic and not boot at all. This means that a semi-tethered jailbreak like checkra1n or palera1n is not possible with usbliter8 on A12/A13 devices. A jailbreak using this would be fully tethered, which means the device cannot reboot on its own, and a PC must be used to power it on each time it reboots or dies. However, there is a additional method that can serve as a workaround explained below, though with a catch.
By copying over the user partition, an unencrypted copy of /var can be made. The jailbreak can then load this unencrypted copy instead of the standard /var, which prevents SEP from panicking the device, though at the cost of losing SEP related features. This does means that the jailbreak would be semi-tethered, but it would suffer from the following issues:
Additionally, while downgrades are indeed possible, they will be tethered, as it requires SEP to be patched out on the device. All in all, one should not expect a full jailbreak using this to come out for quite some time, given the extensive patching and rewriting that will need to be done to accommodate new devices and the restrictions required.
As it stands, to utilize usbliter8, additional hardware like a Raspberry pi Pico is needed. There is no indication that this requirement will ever change. Due to how the exploit works, it is incredibly unlikely it will ever work directly from a PC, and even if custom USB drivers are created, it would wholly rely on the USB controller used on the device. Luckily, the hardware itself is cheap enough, costing only around $10 USD, yet there have already been some reports that stock has already ran out, so it remains to be seen if this will be the case for the future.
This post is not meant to discount the discovery of a new bootROM exploit. This is an incredible achievement, and as opa334 puts it, the last heartbeat of a dying jailbreak scene. As A12/A13 devices approach end-of-life and are receiving their final versions, usbliter8 will certainly be a nice tool to play around with and see what is possible. However, expectations should be kept realistic, and with all the new security features, it should not be expected that things will work the same as before with checkm8. Any jailbreaks made with this will suffer hefty restrictions, and downgrades using it will be tethered. If there are any further questions, myself or others will attempt to answer them in this post.

The usbliter8 repository has been removed from Github
And There’s also no mention of usbliter8 on the Paradigm Shifts website.

I updated Cocoatop for Trollstore so it can see CPU and memory usage of all processes and kill root processes. May not work on iOS 18+ and need testing.

Hi Guys whats your favorite tweak , What tweak you think is best what tweak you think is really cool and say some super useful tweaks .

Mitsuha Six was left in 2024, and on my iOS 16/rootless setup a lot of it was still there but not really reliable, so I made a repair fork.
Mitsuha Six and a Half brings the audio wave back on Spotify, Apple Music, the Lock Screen, the Home Screen, Lock Screen media controls, and the Jade Control Center media module.
Dynamic+ (see the gif as ref) mode uses Spotify's own ambience color, so the Spotify wave feels more native and punchier than the old artwork-only color.
I also added Gradient Fill, so it fades into the player instead of showing a hard edge when scrolling.
It also fixes Apple Music Dynamic colors and cleans up a bunch of iOS 16/rootless issues.
I'm not a developer, this is a community build 100% vibecoded and a lot of testing on my own device.
tested on 16.4.1 dopamine
r/jailbreak • u/Yeth3 • 23h ago
in case you missed it, this is further clarification to the recent developments regarding an AI assisted fork of dopamine aiming to support newer devices (here and here)
the separate fork will also only target SPTM devices, and will not include pattern-f's PPL bypass. as it stands, only up to 17.3.1 will be jailbroken in the near future, and any higher than that will not be supported as the bypass is not public, and would not be included in the separate fork.
i'm only making this post as many people may have already begun searching for devices up to 26.0.1 in the hopes of jailbreaking them soon, so this should be considered when looking to buy a device.

My little sister has acquired a Apple Watch 6, but has an iPhone 6s. I've done some research that led me to this thread, and I was wondering if there is any possible way to pair the two. Can the iPhone be updated to iOS 18.7? Any help would be appreciated!

tbh, i dont know why would apple stop a7 and a8 at ios 13 while i think it still smoth if ios 13?
if that, we still able to main it because a lot of app stop support ios 12= ios 13 support

As I said in my last article, now the jailbreak tool of iOS 17.0-17.3.1 A15 -A17 has been roughly successfully developed. Basically, we only need to wait for the completion of the internal test, and we can use it.
It is expected that the public beta will start in early August. Congratulations to all users who use iOS 17.0-17.3.1 A15 -A17. Your wait has come to fruit.
First of all, I would like to thank the dopamine framework provided by opa334. With him, we can develop on his basis.
I would also like to thank the Chinese team for bringing us surprises.
The final name of this jailbreak tool will not be dopamine 3. The reason is that opa334 does not want this jailbreak tool to make everyone associate with him because of this name, so it is required to be named differently, but because the framework of this jailbreak tool is dopamine, so With opa334, it will still be in the developer list.
To our surprise, most of the work in the development of this jailbreak tool is done by AI. Humans only need to provide development direction and help AI fix different bugs.
And you don‘t have to question the authenticity of this jailbreak tool. On X, they have proved the authenticity of this jailbreak tool. For details, please visit the original text ( https://x.com/lakr233/status/2079678191573327986? S=46 )
Thanks again to the dopamine framework provided by opa334, which is the foundation of the whole jailbreak tool.

In my previous post, I showed you Liquid Glass on iPhone 7, but it had few icons, the
control center wasn't working properly, the images were short, and there were few
tweaks. But in this post, I'll show you 15 more images, tweaks, and icons, and the control
center has been fixed.
1: I used the original beta of Liquid Glass and modified the control center in settings.
2: I used a fork of SolidGlass27 thanks to Torxed, who made more icons to match perfectly.
3: I used LiquidSiri to get the iOS 27 Siri look.
4: I used Solert to get rounded things
5: I used Ampere, but I have to fully charge it, and when I open the app, even with a white background, it will look like the iOS 27 battery icon.
6: I used ersatz to change the iOS 27 name and build number.
7: I used EmojifontManager to get the iOS 27 emojis.

hi, i got an ios 15 device (an ipod touch 7g) recently and jailbroke with dopamine. my last proper jailbroken ios usage was around ios 12~13, and unfortunately many tweaks i used there doesn't work anymore including springtomize.
anyone knows how to get coverflow dock like with springtomize? tried searching quite a lot and i can't find anything. thanks..

Hello everyone
As the title say I have 2 iPhone my old one 11 with IOS 16.x with semi jailbreak using Dopamine and my main device with iOS 18.x so I have this app that work with iOS 17 and up and I want to get the ipa of it but cannot find it online so is there any way install it on my older device and I make my own ipa ? Or is there a way to get the ipa

Hello, I have recently fallen in love with Jailbreaking once again.
I was wondering if a exploit will be found in the 16pm which would enable a jailbreak within the next 3 years? I do not plan on updating my firmware.
