I've read that the Nvidia Shield and the Nintendo Switch both use the TegraX1 chip, and that the bootrom exploit potentially applies to both. I was just wondering, because I was looking around this forum and noticed some devices being locked down over time.
The shield tablet uses the k1 chip not the x1 the shield tv uses the x1 but not the same stepping as the switch which got the newest stepping the Google nexus c had a x1 as does an acer chrome book but none of the above devices needed the boot hack the switch does.
And what would you do with the exploit ?? Shield is very open source and unlockable on its own. And btw, that exploit works on a specific batch of x1 chips, not on k1 if I understood correctly...
That's why I was asking, I wasn't too familiar with the things.
@fpozar Basically even if the things is unlockable on its own, an exploit like that could potentially circumvent any protections you have in place after unlocking.
But it seems like a moot point.

I don't think that's exactly how the things work, even if you did lock your bootloader the most you could do with the exploit would be a data wipe, because since data is software encrypted it can't be read. So your personal stuff is safe from being stolen
The xploit goes back *at least* until tegra 4, ouya console is vulnerable to it, so are all the unpatched nvidia socs older than Nintendo switch

New to Android. But long time user of Linux/RH/Fedora. Are there “distro's” on Android? Can users easily add/remove software with a RPM type management system? In Linux if you don't like TnT you would just uninstall it. Viewsonic g tablet seems to be ok if you manually change a few things. I'm assuming that this is generally a temporary problem due to Viewsonic being behind in their updates. But what I would like to know is there going to be any long term “distro” type leadership going forward? When the new Android Tablet OS is released will it work with most hardware (Viewsonic) like a Linux distro or are we depended on Viewsonic. If Viewsonic let us down can we divorce them and go directly to Android or someone else for automatic updates? Thinking about buying. Can wait for Flash update hopefully in December. Don't see screen as a problem, basically the same as most laptops/netbooks. Can add market manually till it become official with new OS.

Android is not like normal distros.
Being primarily an OS aimed at mobile devices (IE phones) with limited memory and proprietary layouts and internal set-ups, all drivers can not be provided in one overall install. Confliction between drivers would be an issue as well. Also look at many phones (like the nexus one) the Firmware controlling the cellular radio also controls the camera and encoding of videos and images. There is some common ground, but one ROM will not work on all devices without tweaking for the perticular device. CyanogenMOD ROM is a good example, it works on many devices but you must install the proper version for the device you have.
Also remember that we do not have Root on these devices out of the box, 99% of the time we must find an exploit to gain full access to the device. The Nexus one and the G tablet are the only devices I know of off hand without locked down bootloaders. Cellular carriers want the devices looked down so the users can not use the device in ways that the carriers do not want. (like free tethering)
We are dependant on the manufacturer often times to release source code for the device so Devs can rip out the proper drivers and framework for the device. Often times drivers cross over between android versions making updating easier for the ROM devs.
If you want a device that you can truly tinker with, stick to devices that Google has as Developer models. The old G1 the Nexus One and the upcoming Nexus S. Maybe they will release a Dev tablet as well.
The N900 is more open in that regard as far as being like a true Linux, though the future of that branch seems uncertain. It will defiantly be more niche.
Thanks for the reply. I guess I was thinking Android was Linux lite. Not sure where I stand on a tablet now. Think I want a Linux pc in a tablet form. Fedora on a tablet would be fine for me. Like you say tablets with MeeGo (Intel/Nokia/Linux Foundation) may or may not appear any time soon. Have to wait and see what happens.

Android is running on top of Linux, and given programs compiled for ARM you can install about anything, but there's no X... Framebuffer stuff could potentially work..
But no, if you're looking for a typical Linux desktop environment, this isn't the place to look. Although some of the dual boot Windows/Android tablets makes me wonder how difficult it would be to get it Linux/Android.
Thanks for the additional information.
My question is for anyone who already has the Transformer. I understand that it will connect to your desktop, as a mirror. Does this work for Netflix? If you have Netflix on your computer and you connect the Transformer to it, will it stream through properly?
Also, can you connect to your computer if you are at work, or just away from home, or is it when only on the same home network? Not sure I've ever seen this question answered specifically.
Thanks for your info.......
Yes, using the built in software, it should be fast enough. nascar.com uses a very flash heavy app for ausio/raceview and when I use splashtop on my iphone, it works perfectly with audio and their live 3d video with no stuttering.
Cool, thanks......should suffice until the Netflix app gets ok'ed.......
Semi-related question: Are we sure about, hoping for, or excluding the possibility of the NetFlix App coming to this device? I remember some big controversy about most Android devices not being able to run NetFlix due to DRM or something?
The Nvidia Tegra 2 processor basically lacks the hardware DRM required by the RIAA. They have ridiculous requirement, but Netflix has stated it is in the works. Motorola has been OK'd and it sounds like Netflix will come on a device by device basis.
Hopefully some devs will be able to get the Xoom version running on this tab (if it comes to the Xoom, or other Tegra device). Apparently DRM is built into Honeycomb, so I'm the hardware limitation wont matter. It seems like a better way to implement DRM anyway, it seems like it would make the applications more universal.

There won't be a "Xoom" version. There will be a Honeycomb version, which will run on the Transformer, the Iconia, and the Xoom.
You wont be able to just go to the Netflix website and stream, they use Microsoft Silverlight for the DRM streaming
Currently only Snapdragon processors will have Netflix support
Here is a quote about Netflix and the Tegra 2 from January, 2011
"Netflix is using the Tegra 2 development platform to bring the Netflix experience to Android super phones and tablets. We're working closely with NVIDIA to ensure Netflix takes full advantage of Tegra's outstanding acceleration and security capabilities." -- Greg Peters, Vice President, Product Development at Netflix

I was referring to the post above me stating it will be on a device by device basis. While I think it's stupid to do that, it's happened before. Think Skype.
In 2014-2015 it was the ZTE Zinger that was the $10 phone
Well the Zinger is dead but long live the new Zinger: the ZTE Paragon aka Z753G
http://www.zteusa.com/zte-paragon
It's the new $5 / $10 phone
Direct descendant of the ZTE Zinger / Whirl2 / Prelude2 / Salem
same dual-core cpu, same OS (kitkat)
(uses the exact same battery) Correction: very similar battery but slightly more narrow, not same fit
can start and run without a battery exactly like the zinger
But the paragon has improved 1GB of ram instead of old 512MB
also the screen is improved to bare minimum acceptable for 2016, 800x480 on 4 inches, vs the Zinger 3.5 inch 320x480
The Paragon is GSM, but there is also a CDMA model, the Zephyr Z752C:
http://www.zteusa.com/zte-zephyr
The Zinger was impossible to root - the old model Whirl2 with 4.3 could get partial root via ADB shell only. I suspect the Paragon and Zephyr will turn out the same.
ps. looks like the Sonata2 Z755 is directly related as well, same exact phone but with better glass and stereo speaker output? http://www.zteusa.com/zte-sonata-2
Does anyone know if this phone can be unlocked?
So no root for this phone? Too bad. Looks like a good phone for $10.
Based on our experience with the Zinger Z667T and Z667G, not only will this phone be unrootable, it will have write protected partitions.
Unless it turns out like the ZMAX where they missed something but I kinda doubt it.

Do you know why ZTE locked it down so hard? Is there a benefit for them to do that? Isn't locked bootloader make the phone harder to sell?

it probably allows them to sell themselves to phone carriers
When they can show the entire Z667 series has never been rooted or bootloader unlocked, they get the big leagues like T-Mobile and AT&T to show up and buy them for low-end sales of $10 phones
until the Z667 series, ZTE phones were pretty easy to root, the Concord became a little harder before it but even that fell eventually
Kinda surprised the zmax got rooted and bootloader unlocked, I thought it was a later generation but maybe not
Also remember after kitkat 4.4.4 many makes of phones have become very hard to root and bootloader unlocks a pipe dream
I got this phone for my 3 yr old kid because it was $5 - but I cannot figure out a way to even move apps to the SD card! It makes it pretty unusable. I've gone thru a few links about transferring apps using adb but that doesn't seem to work with this phone. Any thoughts about things I could try? Thanks
It may be possible to one-day root this device using the same technique that CrashXXL came up with for Motorola devices that have locked bootloaders. It's not simple but it is not that hard either once someone figures out what files need to be replaced and how to slide in supersu and busybox.
Basically he tricks the device to purposely brick by sending it commands under fastboot mode using pyserial.
That throws the device into qualcomm qload mode which is a very native way to flash to the rom that they use at the factory, etc. Qload drivers for windows x86/x64 are available.
Then he flashes very select parts over the rom with root/supersu in place using that qload mode.
That technique bypasses the write lock the bootloader does and also bypasses signature restrictions (however it does not allow for bypassing efuse and rom downgrades that are monitored by the bootloader)
Once you have root, even without write, you can then use xposed and gravitybox, etc. to make the rom do a lot of tricks normally found on cyanogenmod, etc.
For those that know what they are doing and know how to extract the existing rom using qualcom tools, you can look here to see what he does with the droid maxx/mini: http://forum.xda-developers.com/droid-ultra/general/droid-mini-maxx-ultra-root-pogress-100-t3071609
his pyserial and batch files are in here: https://yadi.sk/d/p458Cy0XineRC/Python
qload drivers are here: https://yadi.sk/d/p458Cy0XineRC/QDLoad9008 Drivers

Looks interesting but definitely beyond my skill set. Thanks for the ideas.
Anything at all on being able to permanently root the ZTE Paragon? (Z753G) Phone has half-decent hardware specs except for the crappy storage (1gb). Sorry for resurrecting an (almost) dead thread, but didn't find anything else on the forums about it and was wondering if anyone came up with a solution.....

Did you ever get your Paragon rooted?
Unfortunately, no. I gave up and spent a few dollars more and found a good buy on a Verizon Prepaid Moto E (2nd gen). Verizon locked their prepaid version of the Moto E down so I haven't been able to find a way to tinker with it (yet!), but it's still a great phone. My ZTE Is currently collecting dust now, and occasionally gets used for something like streaming Pandora, but that's about it nowadays.... It's a shame, really.
Hello, I'm really new to Android devices. In fact, this is my first Android-based device ever. But I do have a lot of experience with Linux and Windows, and it's weird how locked down ARM-based hardware actually is. Android isn't as bad as Apple, but it's still a lot less freedom than I'm used to having. I'm getting the impression that installing custom ROM would be almost as much of a pain as installing the Homebrew Channel on a Wii.
Anyway, one thing that I should point out about my device is that it has no touchscreen at all. It has a touchpad and a keyboard in a laptop form factor, but it runs Android. It has SD card slots, USB ports, and an Ethernet port. It's a netbook with smartphone hardware. I'm curious what I can do with it, and I wouldn't be losing much if I bricked it.
If it were possible, I'd be interested in figuring out how to compile a custom version of Linux for it and flash it to ROM. I really think X with a light Window manager would work well on that hardware. If I can't, though, I would be content with a newer version of Android. It's currently running Jelly Bean and I'm wondering what the new versions are like.
The only thing I've been able to find out about the device is that it's based on a WonderMedia Prizm WM8880, has 1GB of RAM, 8GB of storage, and a 1.5GHz Cortex A9 processor. Mali-400 Graphics. In Google Play, the device is listed as No Carrier WonderMedia GA-1311F. I did a search for GA-1311F, and I found no results.
Note that I don't have an actual Manufacturer or model number, everything I can find digging around leads back to the chipset manufacturer, WonderMedia or some company called WMT. It seems like WonderMedia has ties to VIA technologies, and that they definitely don't make the device I'm using. So that means I have no idea who the manufacturer is.
Is any of this information helpful, or is my device unable to be hacked simply because the manufacturer is too obscure?
Sorry to bump my own thread, but I thought I would mention that I've managed to find out about a method called KingRoot that often works on Android 4.2. I managed to install the APK, but the program got to around 60% and then said my device couldn't be rooted.
I'm not crazy about most of the other methods because they require a USB cable that I don't have. Most Android phones or tablets would presumably have a mini-USB port with a small end for the phone and a large end for the computer, like my Windows Phone does. This machine only has regular-sized USB ports, however, and thus I would need to buy a USB male A to USB male A cord that's capable of performing the same function. I hate to waste the money on it not knowing if it will even work, though. I'm also wondering if I need to worry about crossover vs. patch cables like I would with Ethernet, etc. It's starting to seem like more trouble than it's worth.
There was another method I tried called OneClickRoot, but they told me that I needed to have that same dreaded cable hooked up to my PC, AND pay them $20 on top of it. I'm pretty sure that's ridiculous.
I'm probably going to figure this out eventually, but I'm really frustrated that this is tougher than hacking my Wii was. Embedded systems with non-standard hardware are an amazing pain to deal with.
EDIT: Even thoughc it said it failed, all of a sudden BusyBox installed successfully after I restarted the computer. I think I may have done it, although I'm not sure. Apparently I have a Linux kernel on here already somehow... is that the part of Android that's based on Linux?
imgur.com/HiRyqW2
Still, there's not much I'm finding that tells me how to set up anything much better than using a terminal and a VNC viewer within Android to view a Linux system running on top of it. I guess that could be useful if I had a beefier Android device, but with this it's only useful for a command line.

Hey all,
Preamble: I have a European bought Oculus Quest 2, and during my trip the US I bought the D-Link VR Air Bridge. To my dismay when I returned home I found out it only worked occasionally, due to it using U-NII-3 WiFi 6 frequencies which haven't been approved in Europe yet. However, the Quest 2 should still be able to pick them up - but is probably firmware/software limited.
My idea of a solution is asking a US friend with a Quest 2 for a rip of their relevant software/firmware, and enable these frequencies on my device.
My question is - what exactly do I need to rip out of their device (firmware, modems file, etc.) and how, and how can I flash it to mine? AFAIK the Quest 2 is just an Android device.
Thanks in advance!
Sadly, you can’t. In order to due any sort of firmware build changes or upgrade/downgrades/custom os/etc you have to have the bootloader unlocked.
Everything on the oculus platform (especially the standalone vr) is governed by a sort of “guardian/permission/spy type program. It has to approve any and all device function and requests and it totally locked off without having the bootloader unlocked.
Unfortunately a wild bootloader unlock is Mia. I’m sure someone managed it. But no one spoke up aside from a hoax.
Facebook did release firmware for the oculus go though once it came to the end of its production and sales cycle. This firmware was explicitly programmed with the bootloader auto unlocked. You can install whatever you want within limits if the arm chip on board.
I’m sure if you knew a little about hardware and software dev on the mobile sector, you maybe able to find a work around using the huewei models. Essentially HUAWEI deidtributes for Facebook overseas in some Asians markets to bysoass bans imolimented on Facebook by the countries. They are the exact same device. Same hardware. Different firmware. And most huwawei models have indeed been bootloader unlocked with reports of it being done asap before by tech support while on phone. So yea. It’s a rabbit hole. Good luck
As a workaround, try occur using something like virtual desktop. Super low latency. Make dang sure you are wired the entire way.
The. You can emulate whatever distro you want and view it in vr mode. I have done this with some steam games. Sometimes it works awesome. Some times it sucks utterly. But more often than not it surprises me with performance assuming you have a realivaly decent vr gaming setup (no a rx 589 or gtx 1650 or 1660 doesn’t cut it). I’m talking a ryzen 7 (preferably 9) paired with a rx5700 or higher for amd or ideally a 2060 super or higher for nvidia. Even at these specs, expect barely 50 fps
