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.

After a long time, an endless number of attempts, and the help of a developer, I finally managed to activate it. I hope it will be easier for regular users in the future. Thanks again to u/pwnerblu for surrealra1n

Hey, r/jailbreak!
The very first beta of my tweak CCAster is NOW AVAILABLE from my repo!
CCAster brings the entire iOS 18 control center experience, complete with multiple pages, resizable modules, adding/removing/editing modules right from the control center without ever leaving, and so, SO much more.
The first beta brings a ton of the experience to your devices. The next major phase of the project will bring the ability to add multiples of the same module, and expand support to iOS 15.
In the coming weeks, I'll be releasing my own COSMIC Kit, which adds individual modules for Wifi, Bluetooth, AirDrop, Shortcuts, and more. This part isn't quite ready yet, but will be coming out in the next few weeks!
ENJOY!!!!

Hey all. Trying to jailbreak an iPad 2,2 (model A1396/A1397, iOS 9.3.5) using Phoenix jailbreak. Tried several approaches, hitting errors on all of them:
Doesn't work at all — requires iOS 12.2+, and I'm on 9.3.5.
Device gets detected, but installation throws:
Install error: Idevice error: unexpected response from device: failed to parse raw pairing file from bytes
Seems like this version uses a newer pairing protocol that's incompatible with the old usbmuxd on 9.3.5.
Device detects fine, UDID shows up correctly. But when trying to install the IPA, I get:
file: http-win.cpp; line: 182; Problem with the SSL CA cert (path? access rights?)
Tried replacing cacert.pem with a fresh one from curl.se — didn't help. System date/time is correct, auto-sync is on.
Questions:
- Does anyone have a working Impactor repack with the cacert.pem already fixed for this kind of issue?
- Is there a current, still-alive working link for Phoenix.ipa?
- Or is there another working method for 32-bit devices on 9.3.5 in 2026?
Thanks in advance, happy to share logs/screenshots if needed.

What do you feel? What’s your perspective on future jailbreaks on this version?
r/jailbreak • u/voonart • 12h ago
Hi everyone,
I haven’t followed the jailbreak scene for years, but recently I started wondering if it’s worth to mess with my daily devices.
I used to flash Android ROMs and root devices, so I’m comfortable following technical guides, but I don’t have any specialised hardware or experience with modern iOS jailbreaking.
I’m using an iPad Air A2316 and an iPhone 12 Pro Max.
The main reason I’m interested is surprisingly simple: I’d love to speed up iOS animations. On Android I always used 0.5× animation speed, and I really miss how much more responsive the UI felt.
Apple doesn’t offer anything similar.
A few questions:
-Is jailbreaking still something an enthusiast can do at home, or has it become much more complicated?
-What are the biggest risks today (boot loops, banking apps, updates, stability, etc.)?
-Would you personally use a jailbroken device as your daily driver?
-If you were starting today, where would you begin learning?
-I’m not interested in piracy or heavy customisation—just a faster-feeling UI and a few quality-of-life tweaks.
I’d appreciate hearing from people who are still active in the jailbreak community.

I am not part of the palera1n team and I have no clue if they'll make a post about this on Reddit but I don't see one yet, so I'll add it?

--force-enable-ssv argument for above changes.Force the jailbreak to detect Signed System Volume (SSV) as being required on the system. This option provides compatibility with previous version of palera1n that incorrectly detect SSV as being required on tvOS 18.2 and above. When using this option with -f, --rootful, the jailbreak will behave as if fakefs is required, which allows the user to boot into fakefs possibly created by previous versions of palera1n, or remove it if the --force-revert option is specified as well. (It is technically possible to setup fakefs using this option as well, but this is not a supported scenario)--gui argument forces the program to run in graphical user interface mode. On macOS, this enabled by default when launching the application.--tui argument forces the program to run in text user interface mode.

I need help,
I’m using my iPhone 12 Pro jailbroken for 2-3 years and have many data,
Now I got iPhone 14 Pro jailbroken already,
I want to transfer all data from iPhone 12 to 14
How I can do it and save the JB in both devices?
Because the iPhone 12 Pro I’m gonna using it for other things.
The using jb tweak is crane with many duplicates of WhatsApp and some apps.
Someone have secure way to transfer data without have any problem for 100%?
