hello community,

i want to physically remove the Exynos modem in my Pixel 7.
Can someone please tell me where exactly the exynos modem is soldered and what for chips is on my marked numbering:

If I was successful in my work, i will create a YouTube video tutorial on how to is possible physically remove the Exynos modem.

You can disable the cellular modem's transmit/receive via airplane mode. Samsung manufactures the main SoC so you don't avoid trusting them by removing the cellular modem. The cellular modem is an isolated component that's not completely trusted unlike the CPU cores, MMU, IOMMUs, etc. for the main SoC. If you don't trust Samsung, this won't help you.

    GrapheneOS we are investigating this over here also. We need a physical way to disable any transmission over the air and only connect through Ethernet. We didn't succeed in removing the antenna. There was still some signal left. We checked it with an IMSi/IMEI catcher. The reason we are trying to remove the possiblity is because if a compromise happens, the attacker shouldn't be able to connect to any of the nearby towers.

      For example I have seen a lot of wallets with electromagnetic shielding to protect bank cards.

      It is much easier to use a Faraday cage (or to choose a software solution) rather than tackling the high complexity of hardwares.

        lambd the phone should be kept in a usable state. Your approach is the same as if it turned of.

        GrapheneOS Ideally, I only want to trust Samsung with the bare minimum and operate the Pixel 7 (from tomorrow, the Pixel 8 because of MTE support) with the bare minimum hardware as possible.

        Do you think an expert from the semiconductor industry would help us to tell us how to successfully physically remove the Exynos modem? Who would ideally be the best fit from the list?

        I was primarily thinking of someone from here:

        Nuttso can you tell me where exactly you are stuck in order to successfully remove the antenna so that there is no connection to a tower?
        I have seen that several users, including me, would be willing to donate phones, money so that we can achieve the goal of physically removing the modem.
        Do you think we shouldn't collect the money and get an expert from the semiconductor industry to give us the result?

        Please correct me if I think wrong.
