[Q] Do encryption and custom kernels, etc., play nice? - Xoom Q&A, Help & Troubleshooting

I have a 3G Xoom that's rooted and running CWM and Tiamat. I would like to encrypt the device, since I carry the Xoom in lieu of a phone, and there's a growing possibility that I could be arrested. While the data contained on the device are relatively harmless, I still don't want anyone poring through what amounts to my entire life.
When the Xoom is encrypted, am I able to flash kernels and roms as well as back up and restore through CWM like normal, or does encryption preclude this? Are there any other related operations, especially vis-à-vis root, that encryption prevents?

Good question!

I've been using Tiamat's kernel, and mine is encrypted. It plays just fine with it. I haven't had a single issue.

I've had the same experience.

It has been doing good for me, but a user mentioned that there is a memory leaking issue or something when you enable portable wifi hotspot or USB tethering, although I am sure this only applies to the 3g version of the Xoom, if you own a Wifi only Xoom I doubt this will be an issue for you. Haven't had problems on a wifi only Xoom so pretty sure its for 3g models.

Wi-Fi Tethering Without Root & Bootloader Unlock?

I'm searching for a way to Wi-Fi tether without being rooted & bootloader unlocked. This is one of the primary use cases for my phones, and I've been able to do it for years on Windows Mobile without any additional modifications. I'm pondering a move to the Nexus One but I'm still a bit wary of rooting/bootloader unlocking since it is irreversible. Is there a solution for people like me?
(It must be Wi-Fi tethering, Bluetooth and USB are nice but won't cut it. I have a handful of devices I need to connect such as a Nintendo DSi, iPod Touch, and various laptops).
If you want wifi tether, you have to root.
I don't understand why everyone is so apprehensive to root their phone. It's a painless process. You could go from stock to wifi tether in probably less than 10 min if you read all the steps ahead of time and have everything downloaded and ready to go.
Unfortunately some of us are still apprehensive on the voiding of warranty, especially when we are not based in the US. Once rooted and the phone is on its own, subject to the harsh elements of an unloving world...
Perhaps once the 1 year warranty is over, I will root mine.
It's not the process I'm worried about...I agree its incredibly painless and far easier than other things I've done.
It's the warranty I'm worried about. It seems the general feeling is that HTC will still fix problems clearly not caused by rooting/bootloader unlocking, but it's not 100% official.
Back on topic: any sollutions for non-root users?

That was on topic... I don't believe there's currently any way to wifi tether unless you have root.
That said, since you want to get your DS on, etc... what if you usb or bluetooth tether to a laptop then use the laptop as the wifi access point? It would be less than ideal, but it would get the job done.
True, that's definitely an option, but unfortunately my Intel 4965 wireless card in my laptop doesn't work with the elegant Connectify sollution for Windows 7, so that's not really an option either I suppose I will have to just bite the bullet and root, or stick with Windows Mobile.

Maybe I'm wrong, but I isn't there a difference between Wireless tether for root users and Wi-Fi tethering. I understand there are work arounds, but I can not turn on Wireless tether for root users and connect my PS3 directly. It is not like your phone is turned into a Wi-Fi hot spot. It is an ad-hoc connection. Will the OP's DSi be able to connect to an ad-hoc connection?
Yes, it is an ad-hoc connection you're right, but nonetheless, it can allow multiple clients simultaneously like a router which is what I need. I'm actually not sure about the DS, but devices like the iPod touch and other smartphones can connect just fine.
Well if that's the case, I would just root it. Everything works GREAT! There are somany great applications that become available once you root it. I wouldn't worry about the warranty issue. I rooted my G1 and did all kinds of things with it. If anything ever went wrong it was always an easy fix. These phone are great and the developers behind all the custom ROM's are even better.

Why root?

Being the xoom has sideload what other incentives are there to root? I have an atrix and thing of geting the xoom but w/o custom roms what does rooting do for you? And are there custom kernals if so what do those do thanx

I think the better question is Why not root?
Rooting brings backups, recovery, ownership of the system, customization, and the ability to run modified hulu flash
You don't HAVE to root.
My XOOM is running stock 3.1
I've unlocked my TouchPro2 which sometimes runs Android too, rooted my wife's CDMA Hero and her NOOK Color.
I'm not opposed to rooting my XOOM, I just don't have a NEED to right now.
Its fast enough for my games, google reader and XDA app, I don't need overclocking, and I prefer the longer battery life anyway.
32GB of storage is quite a bit, so I don't need the SD right now, don't have a SD card for it yet either.
All the other little bits of neat things here and there are cool, and would be fun to play with. I probably will root eventually, but isn't necessary right now.
Don't let all this talk of rooting make you think you HAVE to, you don't.
If there's something released that you just absolutely have to have, root then.
Rooting alone won't make unicorns appear or magical gnomes keep your house clean.
But should someone write an app for the gnomes to clean my house, you can guarantee my XOOM will be rooted lol

I am also running stock 3.1. Rooting gives you the ability to do several things with your system because when you are "root" in a *nix environment you have control of everything. You can overwrite files, you can delete files, you can install whatever you want and you can also easily break stuff.
The last part is where users get into trouble.
My advice is always going to be to save rooting for the technically inclined. If you're technically inclined and feel like you can competantly run amuck in your system go for it man there's a ton of fun stuff you can do. If you're the slightest bit leary that you might get something wrong, or don't want to install development tools, etc... stay stock.

Because Google will be blocking movies (and I'll bet Netflix does, as well) on rooted devices. Which then leaves us stuck with how to do things like backup, customization, etc. without a rooted device...

Netflix currenty works on rooted devices. I can't see a logical reason why it would change either. But nothing the riaa does is really logical to me so who knows. But Netflix is streaming only so it is different than a 24hr rental service that you can actually download the file for offline viewing.

Well actually I wouldn't mind rooting the Xoom or the Nexus one I just don't fiddle around with ROMs or kernels. Merely rooting the device all by itself is pretty safe and gets you a lot of things I guess.
I just had my Nexus repaired by HTC a couple weeks ago and they wiped it... even though I don't have all these fancy back up measures in place it took me all of 10 minutes to put the phone back the way it was.

doesn't bother me cos australia can't get movies anyway... i rooted to get more control (for system apps and stuff) and for otg stuff
because you can. root then unroot if you have to.

Yes there are custom kernels. These add SD card support and real micro USB otg hosting, including the ability to read thumb drives and hard drives. That to me was enough to root. I don't want to pollute my Xoom's disk space with 10gb of music and another 10 with movies. Google music beta solved the music and hot swaping USB solved everything else.

[Q] What ROM would you recommend for

a computer tech? I need something that will utilize the wifi card to it's max potential for wireless scanning/detecting and/or mapping. I already have a few apps that are working fine, but i'm not sure if maybe there are any ROMs with updated wifi radio updates.
Also ITT: Apps that make your tech life easier.
Wifi Analyzer
Wifi Scanner
Net Swiss Tool
Network Mapper
What else do you techies use?
the first thing i thought of when i read this was using backtrack (just had it running on my phone). I didn't test any of those features though.
So, overall, i'm no help. But good luck, I'd be interested in the outcome myself.
As far as i know, backtrack works, but you can't use many of the tools because the phone's Wifi radio's do not support injections. However, sniffing works fine i'm sure :]
Though, i was more interested in just maybe a 'toolbox' of sorts for my phone.
Might want to take a look at Shark for root. Its basically wireshark.

[Q] Why Root?

If I am not interested in custom ROMS (at least for now), what are the advantages to rooting a tablet?
Does rooting still break some video streaming apps like google play videos?
U can tweak ur tablet n make it faster...u take charge of it... But this tablet is fast already ...also u can remove any app that comes on tablet that cant be removable

There are no custom ROMs avail for the 300 yet anyways.
However, I have rooted mine and it was well worth the little effort to do it.
Definately beaing able to "de-bloat" the tab is a huge advantage.
Also, you can over-clock the CPU and run apps that require SU permission.
If your comfortable with rooting, its definately a good move.
Blocking adverts and backups at the moment
My #1 reason for rooting is AdFree. No more pesky ads in apps.

Tethering requires root ?
I have root on my phone - Droid A854 - but I can't get the Transformer to connect. It sees the network when I use Barnacle - basically Barnacle creates a wifi access point- but it won't connect. My transformer is stock with the 26 update - not rooted. The other possible methods are to use the stock tethering through USB cable - but no go either. Can't seem to get any traction has anybody successfully tethered their tf300 to a phone.

I have just tested my Samsung Galaxy S2 with CM9 and Wifi tether and all works fine without any issues. So I would start looking at your phone? Maybe test another device to see if that works?

What I was hoping to hear was that the wireless issues are known or that the tablet had to be rooted, or perhaps one program works and one clearly does not. Please let me know what programs are being successfully used - or if you are tethering with USB or wireless. I guess I need to collect what it working and what is not. Your input is greatly appreciated.
I've used the stock Android Wi-Fi tether in MIUI and successfully connected to my tablet.

Sixaxis Controller and Titanium Backup were enough to warrant rooting here, but then I also found LUKS Manager, which is useful if you need encrypted archives.
Overall really the reason to root is that it gives you more control over your tablet. It should in my opinion be default on all devices, but unfortunately telcos would rather not give Average Joe this much power to circumvent things like tether costs.
The reason root isn't default has nothing to do with tethering. Rooting is a huge security risk. There's a reason a lot of Linux distributions completely disable the root account. Root means COMPLETE CONTROL. Anyone with access to your phone while it's rooted (and that doesn't have to be physical access; your tablet or phone is connected to a giant network of potential hackers at any given moment) can do anything they want with it. Did you encrypt your device to protect your information? Doesn't matter when you're running as the root user - you're still ****ed. Maybe Mr. Hacker Man wants to delete /etc/fstab. Say goodbye to your booting device. Maybe he wants to delete your phone apk. No more phone calls for you. He can do whatever he wants to do.
I think you get the point. And no, none of those scenarios are likely to happen, but they're definitely possible with a rooted device, and that's important to know.
Just for perspective, both my phone and tablet are rooted. I'm not saying you shouldn't root. I'm saying you have to understand the potential risks, and I'm saying that phones and tablets should NOT be rooted by default.
Edit: When did XDA start the profanity filter? I don't remember being censored before.
I've never encountered a Linux distro that disables root, and I've tried a bunch. Android's rooting is more aking to enabling sudo than anything else. You're not running as root for most of the time, you're simply allowed to elevate privileges when necessary, just like most distros offer.
Yes it can be a security risk, but then so is connecting to the Internet or downloading an app. It'd certainly be possible to offer an official and convenient channel to root your device, as opposed to having to use exploits or long-winded processes and risk bricking your device for some of them.
The chances of a nefarious hacker attempting to brick your device are negligible. I'd be much more worried about an insecure banking app leaking data or passwords being left as plain-text, but those can be read with or without root as long as the hacker has access in some way (usually a Trojan horse app or 0-day exploit).
And also, you'd be surprised by how much power telcos can have. One of the prime reasons phone users root is because tethering is disabled (it's such a useful feature!) and they don't want to pay extortionate fees just to use a feature that's default for Android.
That's all true, but my point is just that root should not be enabled by default. Ideally, the manufacturers would provide a way to root along with information about Linux and the way root works for the average user's sake. Unfortunately, even if they did that, the average user is "the average user" because he or she would rather not read about how Linux works, otherwise he or she would have already learned about Linux while researching Android phones, and the docs wouldn't be necessary. As it stands in the real world, the only thing the average user knows about root is that they can tether for free. They don't understand the risks or even that there are risks. This is why malware on Android has the potential to wreak havoc.
As for the tethering specifically, it would obviously be more helpful if it was just enabled by default without having to root. But, since the cell networks must extort insane amounts of money from users to use data for which they are already paying, that won't ever happen.
And as for distributions disabling root, I've used several that did so, but the only one I can remember offhand is the one I currently use, Crunchbang. The only way to perform root operations is through sudo, which is fine with me. I had heard it was a growing trend, but I don't believe the major distros like Debian, Slackware, and Fedora have adopted it.

[Q] WiFi Tether... Windows doesn't see it (mac does, as device)

Unfortunately, my friend uses Windows and when his phone is running as a hotspot, he cannot see it as an option to connect to.
I just got WiFi tether to work on my friends HTC One X, on a stock AT&T ROM, using proxoid and android-wifi-tether. When I tested, it I used my MacBook, which saw the connection as a "device." It was not listed as a "Wifi" connection but I was able to use it as a hotspot with no issue.
Does anyone know how I can get Windows to recognize this and be able to connect to it for internet?
not sure why it would show up for Mac but not windows. I thought it would show up as an ad-hoc connection but it didn't show up at all on windows.
Must be an issue with your apps - WiFi tethering is a pretty simple setup process, at least so I've found on ViperXL and CM10.1.

I've never had an issue like this. I'm trying to avoid flashing a custom ROM but will if necessary. Is ViperXL pretty user friendly for an older guy who has a hard time with technology? This phone is for an older friend of mine (in his 50's)... please keep in mind, when I say old(er) this is the tech world... I know you're not old if you're in your 50's

Well, ViperXL is no more difficult to use than a stock ROM. You don't need to touch any of the Viper Tweaks if you don't want to, and the ROM comes with various HTC apps like the WiFi Tethering app. You don't get any of the ATT bloatware, though, so if you rely on any of it, you'll need to figure out how to bring it with you.
