Is My Switch Patched Xkj1 Top Link
consoles are patched against the known unpatched v1 exploit (Fusee Gelee) 2. Can it be hacked? Software Method (RCM):
If you want to be 100% certain, you can verify your serial number (found on the bottom of the console or in ) on community databases:
Look at the small text printed on the plastic back of your console. An unpatched console reads HAC-001 . A patched V2 console (like an XKJ1) explicitly reads HAC-001(-01) .

Not possible. The hardware patch prevents the "Fusee Gelee" exploit from running. is my switch patched xkj1 top
A single bridge or slipped iron tip can instantly brick your system. If you choose this route, it is highly recommended to pay an experienced console repair technician to install it for you. Alternative Options If you do not want to risk microsoldering your
Traditional RCM exploits (like Fusee Gelee) will not work.
If you are comfortable paying for a hardware installation, yes. Once modded via a hardware chip, an XKJ1 console enjoys all the benefits of an older unit—such as game backup management, custom themes, emulator support, and graphic enhancement patches—while also benefiting from the vastly superior battery life and cooler thermal performance of the Go to product viewer dialog for this item.
If your Nintendo Switch starts with , it is a second-generation (V2) unit and is considered "patched." This means you cannot run custom firmware through easy software exploits. While it is still technically possible to hack the console via a modchip, it requires advanced soldering skills and, in many cases, professional assistance. consoles are patched against the known unpatched v1

If you are trying to figure out what to do next with your console, tell me:
Unlike the original V1 (Unpatched) models, you cannot use a simple RCM jig and a USB cable to install custom firmware on an XKJ unit.
These use the improved Tegra X1+ chip. Their serial numbers almost always start with XKJ or XKW . These consoles were built from the ground up to prevent the Recovery Mode (RCM) exploit. How to Confirm Your Model An unpatched console reads HAC-001
— A simple lookup tool for serial prefixes.
Ultimately, determining the status of an "XKJ1" unit requires moving beyond the serial number prefix. While the "1" indicates an early manufacturing run, the only way to know for certain if a specific unit is vulnerable is to enter the "RCM mode" (Recovery Mode) and test if the device recognizes a payload injected via USB. The search for an unpatched Switch has become a niche treasure hunt, and for the owner of an XKJ1 unit, the serial number offers a glimmer of hope, but not a guarantee. It stands as a testament to Nintendo's successful hardware security revisions that, years later, enthusiasts are still combing through serial numbers, hoping to find a unit that slipped through the cracks before the door was shut.
