Few issues get below a technophile’s pores and skin greater than a digital gadget that has been artificially hamstrung by the producer. Certain, that model new gadget you simply unboxed could have some spectacular or cutting-edge options — however not for you! As a result of you haven’t paid an upcharge — or worse but, a lame subscription payment — or possibly even due to the a part of the world that you just dwell in, these superior options will lay dormant as in the event that they weren’t even there. What a waste!
A bunch of engineers at Lagrange Level in Bengaluru, India not too long ago picked up some Apple AirPods Professional 2 earbuds to function listening to aids for his or her grandparents. Given the excessive value of listening to aids, which ceaselessly promote for a number of a whole bunch of {dollars} and up, the AirPods appeared like a very good cut price. Or at the very least they appeared like a very good deal till the listening to support function refused to be enabled throughout setup as a result of it’s not accessible in India. In all equity to Apple, this restriction is almost certainly resulting from native rules, however nonetheless, it was a significant bummer to seek out that out after making the acquisition.

However frustration was not the top of the story for the group at Lagrange Level. Being very technically-inclined people, they determined to attempt to trick the AirPods into pondering they had been positioned in america, the place the listening to support function is on the market. In fact taking this sort of motion would possibly void your guarantee or in any other case get you in some scorching water and yada yada yada, however you’ve obtained to dwell a bit, proper? Hackers gonna hack.
And hack they did. Being a transparent case of a geographic restriction on the function, the staff first tried the straightforward issues, like altering their App Retailer area and gadget locale. Additionally they discovered an Apple net service that gadgets examine to establish their nation of origin. A spoofed response was rapidly ready for these net service requests, and the opposite settings had been modified appropriately as properly.
This simply led to certificates points with the net service and went nowhere. You didn’t suppose it could actually be that straightforward, did you? After failing with different location spoofing methods, it was clear {that a} extra subtle strategy was wanted. iOS gadgets (which the AirPods depend on for setup) can use close by Wi-Fi routers to find out their location. By checking SSIDs towards a database, it’s doable to pinpoint a tool’s location fairly precisely.
Success! (📷: Lagrange Level)
Close by SSIDs had been inserting the iPad used for setup in India, as they need to. To get round that the staff constructed a Faraday cage to dam actual Wi-Fi alerts. Since microwave ovens function at a frequency of two.4 GHz like some Wi-Fi bands, in addition they ran their microwave on excessive subsequent to the cage to behave as a poor man’s radio jammer. The iPad was then positioned contained in the cage together with an ESP32 microcontroller growth board. The ESP32 was then programmed to cycle by way of a set of 100 SSIDs which can be truly positioned in Menlo Park, California, and broadcast them.
Bingo! After a number of reboots — the common tonic for digital gadgets — the iPad believed it was positioned in California and it allowed the listening to support function to be enabled. That may be a fairly in depth setup course of, however finally all that actually issues is that it labored. Should you don’t thoughts spending a weekend enabling a function (and taking the aforementioned dangers), this strategy is likely to be simply what you want in case you get an disagreeable shock whereas organising your AirPods.
