How I Freed My Android Tablet: A Journey in Reverse Engineering (www.thanassis.space)

Posted by EditorDavid on from the longing-for-Linux dept.

Slashdot reader ttsiod is an embedded software engineer at the European Space Agency, and shares this story about his quest to "dominate" his new tablet: Just like it's predecessor, I wanted to run a Debian chroot inside it -- that would allow me to apt-get install and run things like Privoxy, SSH SOCKS/VPN tunnels, Flask mini-servers, etc; and in general allow me to stay in control. But there was no open-source way to do this... and I could never trust "one-click roots" that communicate with servers in China... It took me weeks to reverse engineer my tablet -- and finally succeed in becoming root. The journey was quite interesting, and included both hardware and software tinkering. I learned a lot while doing it -- and wanted to share the experience with my fellow Slashdotters...
He writes that "I trust Debian. Far more than I trust the Android ecosystem," and describes everything from how he probed the boot process and created his own boot image to hunting for a way "to tell SELinux to get off my lawn".

  1. you think it won't get worse? by Anonymous Coward · · Score: 5, Insightful

    At one point in time every kind of personal computer you could buy would be yours.

    Then people started buying locked down devices, which became a bigger and bigger part of the market. Because why not? People buy them, and it's better for the selling company to maintain control of the device so they can exfiltrate your data, lock you into their software store to reap a cut off the top, or disable the device remotely.

    But, generally, you could still get past against-the-owner security in various ways. But companies are learning from the holes, and each generation is more difficult to bypass. Even whitebox PCs are moving in this direction.

    The ownership-era for general purpose computing devices is drawing to a close. Step back to 1970's someone playing with their Apple II or C= Pet and try to explain to them that someday, their computer will take orders from someone else in preference to theirs. They might not even understand how such a thing would be possible, but a million tiny steps have led us to our cages. The next million tiny steps will throw away the key. At each step, people get to argue, "THAT step didn't cause the problem. Why are you complaining so much??"

    Thus ends the potential freedom brought about by the computing revolution.

      Well I think it swings both ways, it's more and more obvious that you don't really control any closed source operating system, you pretty much must have security patches and everything else comes along for the ride and increasingly it can't be configured or disabled. That's the way of iOS, Android, Win10, they're trying to push that model on Win7/8, I'm not sure about OS X but they're probably not far behind. If you want control, you want Linux (or some other open source OS). That said, most people don't felt they were in control at all. By making Apple/Google/Microsoft the gatekeeper, they trust just one source instead of any random exe from the Internet. Same way most people want the CA system instead of messing with peer-to-peer trust. Because when they don't understand - and they won't understand, no matter how much you try to teach them - they end up trusting something or someone.

      That said, what I'm mostly disappointed with is how the world has ended up revolving around a few, huge centralized services. Newsgroups, IRC, Email, blogs and really any kind of service that runs on a network or you could run from your own server is toiling in obscurity, you need to be on Facebook and Twitter and YouTube playing by their rules and if they want to wield the ban hammer there's very little you can do. Personally I'm far more concerned about how we've lost control of the human interaction rather than control over the local machine. And for the most part we don't own things in the digital world anymore we license or stream them, it's all permissions that can be revoked or services that can be shut down. That said, it works surprisingly well until one day it doesn't.

      True. But there's no connection between getting signed patches from Apple/Microsoft/Google and it being FOSS. You can have both. The only reason to lock down a platform so that users can't mess with it *if they want to* is control and money. Taking control away from users and putting it in the hands of A/M/G instead. On cell phones this was justified by the subsidies that cell phone carriers would pay - a carrier wouldn't want someone to buy a subsidized cell phone from them and then switch carriers (notwithstanding that this could just be enforced by ETFs and the like), so cell phones were locked down to remove root access to them. And because cell phones were, tablets have followed along, since tablets are just cell phones with larger screens.

      Google does the minimum to be compliant to the GPL, and Apple and Microsoft barely even pretend. Windows 10 is a disaster for many reasons, but the biggest one to me is that it has finally removed the notion that the owner of a computer is, you know, the owner. Who can modify it to fit his needs as he wishes. Now you're just a user, and even with administrative privileges there are things you will not be allowed to do inside the OS.

      Coincidentally this article came when I am upgrading phone and tablet, which is also an asus, so I am set up to try some of the hacks you have described. I'm keen to see if the serial ports are on the headphone ports of the phone also. Perhaps they're used as a diagnostic port in the factory?

I only ever considered them to be used as a way to access the AT command set to use features of the phone like a modem. But a serial console, of course, it's been mocking me the whole time.

      I was also considering your predicament from the SELinux perspective and hierarchy of privileges. Busybox includes getty. Back in the day this was used to spawn a login on serial ports for serial terminals. It was common practice to spawn them from init, using inittab. I noticed you could get logins appearing before the rc process was finished. It also controlled where root could log in from and whilst generally restricted to the console, you could allow it on a serial port.

      Obviously, this depends on if the SELinux policy allows init to read an /etc/inittab file - but there is only one way to find out. If it does, you maybe able to get the same privileges in the hierarchy as rc by simply bypassing it. This also leads to considering spawning the telnetd (or even sshd) directly from inittab, however I suspect that the SELinux policy might react in a different way to them than getty spawning the shell.

      Frankly, I've only just got interested in android and your submission could not have been more timely. You triggered a cascade of memories and a bunch of stuff I want to try on the gear I have for the same motivation, I want all of the functionality of the device I own.

Another source of more recent ROMs is the XDA developers forums. Basically, when it comes to popular devices there is quite a bit of ROMs out there. For example, Nexus 5 updates ended at 6.x, but there are 7.x community ROMs. I have LG G2 smartphone whose last official ROM was Lollipop 5.0.x, but there are community supported 6.x ROMs for it, and even 7.x ROMs by now. Any of those alternative Android ROM routes is a better way to get access to more recent applications on outdated Android hardware, then running a Linux distribution.

      Sadly, it's going to take a bit more to amuse me. In this age of ubiquitous wifi and smartphone tethering, I am not sure why I'd need to amuse myself with an off-line copy of a web site. Ok, maybe it could work out for a long flight or something.

    Always-connected Internet made securing your machine impossible. This was the innovation that took away permanent control over your machine. After all, you "need" to install security patches so *other* programs or people on the Internet can't take over your machine, right? This means you can never "fix" your machine to a set configuration. You trust someone else to update your machine, and these updates keep control over you.

    But why? There cant be a need for that.

    Apple iPads are the locked down devices. The "walled garden" devices.

    Android devices are the open devices.

    I'm sure of it. Slashdot told me so.

    Repeatedly.

    There ain't any good humor left on Slashdot these days. I guess the biggest casualty of this election is, no matter who wins, is the death of genuine wit in a large section of population - namely Trump supporters.

    "It was as if Android creators absolutely HATED people like me, and did their best to make us suffer; because they group us together with malware authors; and add multiple layers of checks that don't distinguish between the owner of the machine and the developers of applications that run in the machine."

    Android it's there and supported boards are not so painful to setup.
    The point is OEM want to protect their IP and avoid thinkering.
    In some case they even don't know themselves how to make some stuff work and put in place awful workarounds (e.g. china tablets roms, Samsung :D ...) because the provided BSP is already a mess.

    I used the one clivk root that talks to china. I then used the permisions to the file system to rewrite the boot sector and recovery. Then used unlocked boot and recovery to rewrite the device with the rom of my choosing with an open source root. Then booted and scanned to ensure the one click rooter was no longer present, remove any potential reminant and your done.
