Few issues get beneath a technophile’s pores and skin greater than a digital gadget that has been artificially hamstrung by the producer. Positive, 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 price — or possibly even due to the a part of the world that you simply reside 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 steadily promote for a number of a whole bunch of {dollars} and up, the AirPods appeared like cut price. Or not less than they appeared like deal till the listening to assist characteristic refused to be enabled throughout setup as a result of it’s not out there in India. In all equity to Apple, this restriction is probably because of native laws, however nonetheless, it was a serious bummer to seek out that out after making the acquisition.

However frustration was not the tip 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 have been situated in the US, the place the listening to assist characteristic is on the market. After all taking this type 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 bought to reside somewhat, proper? Hackers gonna hack.
And hack they did. Being a transparent case of a geographic restriction on the characteristic, the staff first tried the simple issues, like altering their App Retailer area and gadget locale. In addition they discovered an Apple net service that units test to determine their nation of origin. A spoofed response was shortly ready for these net service requests, and the opposite settings have been modified appropriately as properly.
This simply led to certificates points with the online service and went nowhere. You didn’t suppose it might actually be that simple, did you? After failing with different location spoofing methods, it was clear {that a} extra subtle method was wanted. iOS units (which the AirPods depend on for setup) can use close by Wi-Fi routers to find out their location. By checking SSIDs in opposition to a database, it’s doable to pinpoint a tool’s location fairly precisely.
Success! (📷: Lagrange Level)
Close by SSIDs have been putting 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, additionally 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 might be truly situated in Menlo Park, California, and broadcast them.
Bingo! After a number of reboots — the common tonic for digital units — the iPad believed it was situated in California and it allowed the listening to assist characteristic to be enabled. That could be a fairly intensive setup course of, however finally all that basically issues is that it labored. If you happen to don’t thoughts spending a weekend enabling a characteristic (and taking the aforementioned dangers), this method could be simply what you want in case you get an disagreeable shock whereas organising your AirPods.
