Ah, and just as I read this, I find that cyanogenmod for the galaxy s has recently become stable. I now have a hot date with an exploitable bootloader.
I've been running some sort of dodgy leaked nightly build from samsung that doesn't have any carrier shite on it since I got the thing, so maybe it hasn't been there all along. Either way it's high time for some new firmware.
As others have said here, you can remove this stuff all you want, all you're doing is shutting off the simplistic application layer backdoors. There is absolutely nothing you can do about the backdoors built into the baseband firmware itself, which is what law enforcement agencies use.
Well, absolutely nothing except flashing your own open source baseband firmware from the fine folks at the OsmocomBB project. Unfortunately that project only targets a very small set of simple featurephones, which won't do much to excite HN types. What may whet your appetite however, is the possibility to inject arbitrary packets straight into the GSM network! The possibilites for fun, learning, and prison time are endless.

- ajross 15y agoYou don't need an exploit to install ROMs on Galaxy S variants (and in general most/all Samsung smartphones). The first stage bootloader supports partition rewrite over USB using a leaked "Odin" tool (or the open source "Heimdall" tool built through reverse engineering).
- JonnieCache 15y agoI used to use the Odin thing, but it makes me nervous. Heimdall doubly so. There's now that "ROM Manager" app in the market, which manages to flash firmware starting from userspace. I haven't looked into how it works, but I assume there's an exploit involved somewhere.
- wx77 15y agoI believe ROM manager works after you have successfully gained root on your device and not before. It may have changed since I no longer have an android phone but when I had my droid the process was install a rooted version of your current OS then you upgrade from there. ROM Manager just made the installing other OS's and extras and keeping cyanogenmod up to date easier.
- nodata 15y agoAny chance you could document your experience with Cyanogenmod on a Galaxy? What works and doesn't, what kind of uptime you get, etc.
