Online Tools

Here you can find some of my online tools since they would occupy too much space in the navigation bar on the site.

I make all sorts of tools to fit my use cases, but if you find any of my tools useful feel free to bookmark the page.


iOS SHSH2 Blob Checker Online: Can You Downgrade?

This tool reads an iOS SHSH2 blob and pulls out everything inside it: the device model, ECID, chip, board, the exact build and iOS version, the ApNonce, the generator, and which restore tickets it holds.

It parses the AP ticket by hand and checks for Cryptex1 data, so it can tell you whether you saved a complete blob or only the AP half, which is the mistake most people make on iOS 16 and newer.

More importantly, it gives you a straight answer on whether that blob can actually downgrade your device.


iOS Sideloading Certificate Checker (P12 Revoked & Expiry)

This tool reads a .p12 signing certificate and shows you everything Apple put inside it: the identity and team it was issued to, the certificate type, the day it was issued, and the day it expires. It also checks if the certificate is REVOKED or EXPIRED, so you’d know if you can use it for iOS Apps sideloading.

It is built for the people who actually deal with this: developers, sideloaders, and anyone whose apps died overnight and who needs a straight answer.


iOS Provisioning Profile Checker (.mobileprovision Viewer)

Read any iOS Provisioning Profile (.mobileprovision profile) online. See the type, team, App ID, expiry, entitlements, signing certificates, and every device UDID in a searchable list.

Provisioning Profiles are very important for when you want to sideload iOS IPA applications with any signing service or tools like Sideloadly and AltStore, so a valid Provisioning Profile makes the difference between the app running or not.


iOS Configuration Profile Checker (.mobileconfig Viewer)

This tool opens an iOS configuration profile (.mobileconfig) and shows you exactly what it would do to your device before you install it.

It tells you whether the profile is signed and by whom, whether it can be removed once installed, and it breaks down every payload inside with a risk flag on the ones that matter, like root certificates, MDM enrollment, web filters, proxies, and DNS changes.

Configuration profiles are one of the easiest ways to get burned on iOS, since the same file that adds an office Wi-Fi network can quietly install a certificate that lets someone read your encrypted traffic.

If you have ever been told to install a profile to unlock a feature or fix something, run it through here first and read what it actually does before you trust it.


More tools will be added here as I make them, so feel free to bookmark ๐Ÿ™‚

GeoSn0w
Hey! Iโ€™m GeoSn0w, also known online as @FCE365, a jailbreak enthusiast, reverse engineer, and developer since 2015. Iโ€™m the creator of iDevice Central, a blog and YouTube channel dedicated to exploring iOS internals, jailbreak development, reverse engineering, and the fascinating world where software meets security research. Over the years, Iโ€™ve covered and contributed to countless topics in the Apple jailbreaking scene, documenting exploits, kernel patches, and low-level system tweaks. My goal has always been to make complex technical concepts more understandable for those who want to learn, not just to use jailbreaks, but to understand how they actually work. This blog reflects my journey through reverse engineering, coding, and experimentation with iOS, macOS, and even game engines like Roblox (Lua). Youโ€™ll find articles, educational guides, and insights that aim to teach, not to promote hacking or unauthorized access. Everything here is shared for educational and research purposes only. I believe in curiosity-driven learning, responsible disclosure, and keeping the hacker spirit alive, ethically.
