Are su/sudo available in android, can root be performed without rom flash?

Hello guys, seem like I will be moving to this part of xda in a couple of weeks
I have several questions though, mostly regarding roms and rooting. I have used linux for sometime and from what I understand su/sudo/gksu/gksudo etc. are not available in android? I mean I cannot gain root access in the same way as on the desktop. And if I root the device it will not lose warranty, as I can unroot it later on similar to SPL/HardSPL in winmo. The other question is, I think I am going to be OK with the stock rom, as the desire is some pretty fast hardware, so can I root it without installing rooted rom, again as HardSPL in winmo. I will probably need the root access for some applications, like task manager, otherwise I will probably only use the phone, browser, mp3, social stuff, gps, email, videos like I did in the past.
I am sorry if these questions were asked before, I read the tutorials in the first post, however things are still not quite clear for me

You don't have to install a custom ROM if you use unrevoked for root, it just adds the superuser app to your current ROM. However it will flash the recovery, so it voids your warranty anyway. There is no way to avoid this.
No idea about su/sudo though, I know nothing about linux

Well,I kinda have the same questions...First off,there is the su command in Android which is equal to the sudo command in Ubuntu etc.To give an example,I was trying out the ezHero rom on my Hero the other day and jit was enabled with this process:in terminal emulator you type in su,and then it asks for superuser permissions(probably only available through root?) and then you type jit-on and some other things happen that don't really matter here.I believe I answered half your question.Now,if root can be achieved through terminal...I don't think so!It's above my head though...

Thanks guys, that cleared up a lot
About this recovery, I guess if I can unroot and flash "stock recovery" if there is such a thing, it will not be a problem, is this the case? If I can't maybe I should buy a used device instead of a new one.
About the su/sudo, I have used mostly Ubuntu, and in the users menu I usually had 2 users - admin and root, once I set up a root password. Then I used the admin user and if I needed root access for something I did it with su or sudo + <command>, requiring password, or if it was software launcher requiring root access with a path gksudo + <regular parameters/command> in the launcher properties. For example, as far as I know you cannot change attributes like readable/writeable or edit files which are not personally belonging to your user without root access . It is a really neat and simple feature on the desktop and I am puzzled as to why they removed it from the stock rom. I didn't include this in the original post so that it is not too confusing.
Anyway thanks guys, having been with winmo for the last few years, I will finally give android a go and see if it works for me

Yeah it is relatively easy to flash to complete stock ROM and recovery. There's a guide somewhere in the developer board.

No. Just no.
There's nothing in the warranty agreement to suggest that (there is a line that confirms that in the N1 agreement, though), and countless people have sent their rooted Desires back to HTC for repairs, and they've all been repaired. They just won't repair it if the ROM you flashed broke some hardware (ie overheated the LED and made it short-circuit).

Thanks guys, then I'll get a new device, great

help unlocking NAND after using unrevoked

I'm a noob at Android hacking and wanted to root my evo After a few questions to one of my friends, he pointed me towards unrevoked3. Now am stuckand don't now how to unlock the NAND and its driving me crazy. I want to be able to use roms such as damage control. Please help. Im compleatly lost.

I would ask your friend, don't think many here use unrevoked, we used the complete method from toast.
Also read through the posts in the Dev wiki.

I just rooted and unlocked last night...had a few issues. Should be around most of the evening. Where are you and what did you do?
Last night I used that unrEVOked3.1 software and then moved on to unlocking. You will need to ADB installed to do it the way I did it. This is a component of the Andoroid SDK. (You can find that from the google android site.) It is complicated and I got through it because I am old enough to have actually worked in DOS back when there were dinosaurs.
It's not impossible, there are instructions out there...but it will take effort. Hate to point you away from xda...'cause LOTs of good work here...but I followed the unlockr.com tutorial for unlocking nand.
http://theunlockr.com/2010/07/20/how-to-unlock-nand-on-the-htc-evo-4g/
There were a couple issues where su couldn't find the sdcard. I even did lists and saw it, but the commands failed at start. Took a mix of unplugging usb and replugging and mounting and just charging....not sure what fixed it...LOL. But I got the commands to run eventually.

You can use Rom Manager app to install CM7. In fact Rom Manager is included in CM7 Rom. Honestly I think Rom Manager was made mostly for CM Roms. Make sure you wipe data, cache and davlik before going to CM from another Rom. I never flash through Rom Manager app and always flash manually from recovery, but a lot of people do flash through Rom Manager. Good Luck.
Also just to clarify(someone correct me if I'm wrong),
I think if you used the unrevoked3 app from this thread Unrevoked to root your EVO that it also nand unlocks it too. The thread doesn't state it, but the app has been updated to work with the latest hboot, so it should work on all Evo's right now. I could be wrong, but I have used the latest Unrevoked to root all of the Evo's that I have rooted and have never had any problems with backups, restores and flashing Rom's.

and i got titanium back up for my apps but not sure how to use it i got idea of hot to use it and how can tell if my nand is unlocked or not

power off your phone then go into bootloader using power+vol. down..if you see s-off at the top the youre unlocked

If you are s-off, but still having problems with some root apps, you need to install busybox. You can do this from the "problems?" button in the bottom right of the overview screen in Titanium Backup. Then choose "get busybox".

Questions about rooting an EVO

Let me first say I'm a noob to this whole rooting thing and I would like to get some more info on. I tried searching the forums for the answers, but I failed to find what I was looking for.
1) What is this nand people are talking about? RUU? ROM (what's the difference between sense and no sense)?
2) How do I backup my apps, etc before trying to root?
3) Which guide do I use? My Evo came with 2.1, but I did the stock update to Froyo.- I don't wanna end up with a 500 paperweight.
4) If I need to bring my phone in for service how do I return it to stock?
5) I know you can turn your phone into a free wifi hotspot after rooting, what are some other advantages to rooting?
Any help would be greatly appreciated.

ok now let me remind you im not far ahead of you so let me tell you i would wait for a few more posts before taking what i have to say to heart, but i cant leave someone i may be able to help (even a little in need)....
1. the phrase "NAND" refers to the term nandroid backup, which is when you create a backup file. like a system restore point for windows, so when u start doing some different customizations or just try flashing some different roms assuming something goes wrong you will always be just one click away from doing a restore back to a fully functioning rom that you backedup previously. i believe the 2 main programs associated with this is amon_ra and clockwork.....
2. as far as backing up apps i just save the .apks on my pc and reinstall them once i reflash a new rom, but from what im reading you can use a program like titatnium backup, app brain...etc. but then again as far as personal experience goes...none here just what ive gathered from reading.
3. http://forum.xda-developers.com/showthread.php?t=765496
(personally ive rooted with this method and it was very simple just read through the steps before starting and follow them accordingly, dont be discouraged general computer knowledge is needed though) or atleast the ability to move about the computer)
4. returning your phone from the method discribed below is simple as it seems...but again have not done personally only from what ive read: you are rooted (assuming you've used the thread above) with unrevoked3 meaning you have s-off(in laymen terms: the position of the bootloader {ON or OFF} which checks images being flashed to make sure they are signed with the htc security signature),,,you just need to download the unrevoked s-ON file and use that to return the phones security settings and re-download an RUU(RomUpdateUtility) thats official from the htc site and ull be back to unrooted good old-fashion stock evo.
5. and as far as the wifi tethering goes just go to the market place and download a wifi tethering .apk, once rooted of course ....and run it from your evo to connect to your pc wirelessly
*this should help*
http://handheld.softpedia.com/progDownload/Wifi-tether-download-76020.html
and as far as why root, well because when you buy a phone i assume you wanted it to be YOUR phone and with rooting its all about flashing opensource/custom roms to your phone and other things such as kernels to customize the phone to your liking and you cant flash unsigned data to your phone without having su permission, meaning you need ROOT access....
-now again let me disclaimer myself i am also very very new to the whole android community and may be spewing lots of wrong info and am probably quite confused my self but i figure id risk making a fool of my self to help u in the off chance that what im saying makes any sense at all....but yea

If I can root a phone trippin on 28 triple cs you can do it

Boss dextromethorphan.....is no fun, and I dunt suggest rooting ur phone or opperating heavy machinery under the influence of triple c's....

Who should I get my root from?

I'm thinkig Unrevoked team. Should I do Unrevoked3 or forever?
Please any ideas? Custom recoveries or ROMs?

Hahaha research
Unreevoked 3 and forever are two totally different things. Foreverr is now obsolete with the release of 3.2.1. I wouldn't use unrevoked because then you have no idea what root is and how to use it. That's my two cents.

I will be using unrevoked 321 tomorrow to root my new evo. My first evo I rooted using simple root.
I disagree with dkdude36. I did it the hard way when the g1 dream first got rooted. The process is academically enlightening but a waste of time really.
Go for the easy root (unrevoked) unless u have a lot of time to spend learning.

I disagree with jdbiggles...
If you understand how to use a terminal (ADB) and know how to type without error, "the long way" doesn't take more than an hour to obtain root access to your evo!

My personal opinion is to get root with ADB. The things you learn will help you in the future.

Root with unrevoked, as it gives you one step nand unlock and everything. However, if you are not willing to learn ADB and the such, do not root your phone at all.

If this is the first time you have ever rooted an android or HTC device I would recommend doing the "long way", not because it is some stupid right of passage, or that I think you are a dumb n00b if you don't, but because I think that it will help you a lot in the future if you ever run into problems. You don't want to be learning about all this stuff with a bricked phone.
My first experience with rooting / custom roms / adb was with a G1, and then with a Nexus one. This time around, I simply used unrevoked, but that is because I already understand how the process works, and just want to get it done. It is kinda like math class, they make you write it out with pencil and paper, and then only way later can you use a calculator, because if you never did it long form, you would have no idea if the calculator was right or wrong, or any clue of where you made a wrong calculation.
If you run into any problems now or in the future with an android device, you will actually be able to at least sort/solve the simple problems, before needing to post here and wait for an answer, and hope someone posts step by step instructions.

Below are questions I posed in another thread. The root question is apropos to this thread. Can someone please provide me with some direction? I don't mind doing the "manual" way.
Thanks.

1) Is there now a way to use pattern lock only? The Evo still shows the drag down HTC screen lock even when pattern lock is enabled. I have searched all over, have yet to find a solution.
I don't want to run a custom ROM. Will a root give me some ability to disable the drag-down lock?
I also have a Nexus 1. When I enabled the pattern, the regular screen lock is turned off. That is the behavior I'm looking for with the Evo.
2) Root: I want to root to enable all apps to SD, copy files, enable "reboot", etc. I do not care to run a custom ROM. I don't mind having to re-root after an update. I do not want to wipe my phone. I WANT to maintain the ability to receive future OTA updates.
On the N1 platform, there is an easy root method to allow for this. I get Superuser, can run root apps, but still receive OTA and no custom ROM. I'm looking for the same here.
For the Evo, which method whould support this?
I would very much appreciate any help.
Cheers.
Edit: I know what a generic NAND memory is. In this case, why is NAND protection and why does it need to be disabled? What is "S-On/S-Off". I looked through the guides/FAQ, but haven't been able to find anything. Thanks again.

I have rooted my G1 before the long way. I understand how it works, just wanted to see if there were better teams to get it from? But I think this clear, unrevoked forever.3. 2.1 doesn't work anymore?

[Q]All of my G2 Root/Unroot Questions

[Extremely Nooby Questions Below]
So, I looked through the forums and didn't find anything that applied to the G2, or told me what I needed to know, so I need some help. This is my first Android
device and I like it so far.
My first question is about the "VISIONary" App. I installed this about a week ago and along with it I installed "Titanium Backup", "Shoot Me", and "SuperUser" just showed up somehow. I've been seeing many people say that "VISIONary" isn't too reliable. So, if I want to try out, the RAGE version of the temp/permaroot do I need to uninstall all of these apps? Or Just Visionary?
Also, to uninstall visionary, so I need to press the "UnRoot" button, and then uninstall, or can I just uninstall.
I also thought that, "adb" was the same thing as rooting. According to the Wiki , they aren't. So I need to do both to successfully root the G2?
Is "OverClocking" a completely different thing too?
What do I have to look out for while trying to root my phone? Any precautions to not brick my phone.
Also, I found a really good youtube turorial - /watch?v=zdmtkHkrgLE - to Root, a Droid, are these the same instructions to rooting a G2?
Thanks in advance. Oh and by the way, I didn't know whether to put this in development, (Since it was about Rooting), Or Q&A, since it had questions in it.
If I need to move it, please tell me.

I'm not trying to be mean but these questions have been answered many many times before.
You need to read and read and read some some.
I would suggest you check the wiki and look in the dev forum. There is plenty of info you have to look for it.
Follow the directions for your specific device only

I'm no expert myself, just an average user who depends on the work of this awesome community to learn a little bit more about how these things work, so take whatever I say with a grain of salt.
I think all that matters for rooting purposes is removing VISIONary as the wiki states. As for how exactly to do this, not sure since I've never used it myself. Since it's just a temp root anyways, I'm pretty sure if you uninstall it and reboot at any time, it will be unrooted anyways. Titanium Backup will not even work without root, so you might as well remove it too (although not sure if you have to). I'm not sure what Shoot Me is. If you're in doubt, removing it before you root and reinstalling might help, but I doubt it's necessary.
The rooting instructions for the G2 are very specific. Do NOT use the same instructions for the Droid from that youtube video. I'd only recommend following instructions specific for the G2 you find on this site. This right here is definitely the best way I know to do it:
http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Rooting_the_G2
I'd had some experience playing around with rooting my G1, but I never needed to deal with adb and was also initially confused. It's basically a shell that you can use to communicate with your phone when its plugged in via usb to your pc, using a command prompt or terminal or something. The instructions for setting it up aren't 100% clear from the wiki, but this guide was amazingly helpful in learning how to set it up in Windows:
http://forum.xda-developers.com/showthread.php?t=865685
Once you have that running, following the recommended rooting method from the wiki (rage/gfree) is seriously a breeze. Just follow it carefully and you won't brick your phone. The devs have really simplified the process for us in a short period of time.
This was also a really helpful FAQ that pretty much answered all my initial questions when it came to rooting, if you read through all of this carefully, you'll be able to figure it out pretty quickly:
http://forum.xda-developers.com/showthread.php?t=835777
Also, if you plan on installing a custom rom like cyanogenmod (highly recommended), you may want to back up your copy of swype cuz you'll lose the swype keyboard when you do it. Here are some good instructions on how to keep that:
http://forum.cyanogenmod.com/topic/10225-how-to-keep-swype/
Overclocking is a completely different game. Once rooted, you can use an app like SetCPU to speed up the clock speed on your phone's processor (stock is 800 MHz). I've seen some people able to achieve speeds of 1.9 GHz or so, but what's more common is around 1.4 GHz if i'm not mistaken. Obviously, for the increased, performance, you'll take a hit in battery life and such, you probably dont want to push your phone's cpu too far if its not necessary. Rooting gives you the option though.
Lastly, if you want to unroot, there are more complicated methods posted if you use the older rooting method which is currently not recommended. For this method, you can basically follow the instructions in this post:
http://forum.xda-developers.com/showpost.php?p=10349347&postcount=81
from this thread:
http://forum.xda-developers.com/showthread.php?t=835971
The PC10IMG.zip can be found in the original post of that thread. The instructions for turning S-on via gfree are also found in the wiki.
I know that's a lot, but hopefully it will answer a lot of your questions.

Small corection to the post up. Am not expert but I just did.
Set cpu will allow U slow down to 245 Your cpu or go 806. To go more then stock speed U have to flash new kernel and this metod is permanent overclock with will keep settings after reboot phone. Second metod is easy way using scripts. U can find scripts on xda. This will give U 1400.
Don't forget to setup profiles on SetCpu with save U Battery
