I assume that will only work on stock rom ( there are no customs for now). I can factory reset my Hero but will only loose root when i flash a original update
My optimus will be delivered in about 4 workdays

Hmmm, just to test it I used the unroot function of SuperOneclick and it works fine as far as i know .

Hey,
could someone else please confirm that it's that easy like described by Korumera?
cheers

I tried the unroot button from the super one click program. and that is working.
resetting to factory reset will not unroot your phone. The super user apk was still there after reset, and still working.

Just delete it with root explorer.

wrong post ... sorry

can confirm that a factory reset don't unroot the phone, going to try the other method cus mine is going back to be replaced

Just use the unroot method I said a few posts back that works perfectly fine.
Open SuperOneClick, press Unroot and your done. If it didnt remove the superuser app just reboot your phone.

Hmmm how bout flashing back the old official KDZ http://www.lg-phones.org/lg-optimus-2x-p990-firmware-download.html

I can't connect my phone to the PC using USB, so I have to unroot manually.
Just need to run this by you guys before I do anything;
To unroot manually, I need to mount system folder as r/w and do the following:
1. delete /system/apps/Superuser.apk
2. delete /system/xbin/busybox
3. delete /system/xbin/su
4. reboot
Is it okay to delete the entire xbin folder?
From what I see the files inside xbin belong to busybox.

"xbin/su" is usually a symbolic link, the real "su" is in /system/bin (in most configurations. Depends on how you rooted.)
On a stock rom the xbin directory exists, with one file in it: dexdump.

Thanks Trym!
So what I did was moved /system/apps/Superuser.apk to my sd card using root explorer and unrooted without PC using z4root.
Now I think it's completely unrooted.

Just use nvflash guys
Best method.
It will restore everything back to stock, like the first time you boot ur device.
It works even if you have a custom rom onboard.

So if i have CM 7.2 on my device and i want to send it back to the warranty just use nvflash and it is all back to stock?

hi guys,
where can i get the official froyo roms and Nvflash?

Why not searching in dev section?

I've uninstal busybox and Root was gone ...

You may use unclockroot ( [unlockroot.com) , you can unroot your device in -30sec
Its very easy

Would using ODIN to flash back to stock and using the Master Clear remove root?

ODIN back to stock will remove everything and put it back to the state that the phone was in when you took it out of the box. You will, however, still have some file system stuff hanging around from before. You'd have to clear your SD card of that information. But you should be unrooted and back to normal.
So if I were to use ODIN, could I still use Titanium Backup to get all my apps and games back? Because I want to go back to stock without root, but still have my apps and the info for them too.
nope - titanium backup needs root to work
Why the concern about root?
I just feel like going back to stock for a while, no real reason.

Unless you've really made some major changes, i.e. new ROM, Kernal, radio, you are at stock. You could just flash to stock, root, re-apply through TB and you still are at the base of the phone settings.
So TB will still have my stuff even if I do the flash? Or do I need to save the backup to my computer?

Save back up to your computer if you are going to master clear. If just odin flash not necessary
If you're still wondering about this, I unrooted using the root file found here:
http://forum.xda-developers.com/showthread.php?t=884364
Then, I unrooted using the unroot.zip file found in the Galaxy one click root/unroot rar file. In both cases, you copy the file to your phone's root directory and then rename it to update.zip and follow the procedures in the thread linked above. Linke for the galaxy one click root/unroot is here:

[Q] Get rid of superuser permissions

Hello, i have a Nexus One, Android 2.2.1, build FRG83D.
I bought a 2nd hand one, it has installed te Superuser permission but seems not rooted, i mean i tried several tools like titanium backup, that need root acces and they didn't get it.
I tried get root acces with universal androot, it says that its already rooted, i try to root it again, it fails.
Im wondering what can I do, I was thinking in flashing to a original rom, not cooked, but im not sure if i need root acces to do that.
How can I delete Superuser permissions and root the phone properly?
I'm new in android and I'm getting a little lost here.
Thanks in advance.
Now I'm just a noob myself with this stuff too. It sounds like u got it 2nd hand if so I would find an ruu or what ever is required to get ur phone back to original out of the box state. Then try again. But make sure to get one that is rootable because I have seen ones that aren't.

You probably are rooted. However, some root apps (like Titanium Backup) require busybox to be installed as well as being rooted (otherwise those apps will give you an error saying you are not rooted, even though you are). Just install busybox from the market, and you should be fine.

You don't need to flash a cooked ROM if you don't want. Just flash a pre-rooted stock ROM, like this one: http://forum.xda-developers.com/showthread.php?t=968396

I suspect it was rooted, but got an OTA update at some point, losing root, but keeping the Superuser apk and possibly even su and busybox, but without the necessary privileges...

Then you are not rooted. You just have the Superuser application installed on your phone (does not give root access). Re-root like danger-rat indicated.
EDIT: danger-rat beat me to it!
Just Rooted my phone, following the method danger-rat posted here.
Thanks a looot!

Initial setup/best practices

Soon-to-be, first-time, smart phone owner here.
My new Revolution is on the way and I have a few questions for current owners, rooters and rom installers.
I want to remove bloatware and Bing, improve battery life, allow tethering, and unlock the FM radio. Should I wait for Gingerbread? Root only? Install a custom Rom?
I know that the rooting process and roms improve over time and would also appreciate some input to the most current root/rom process.
Thanks,
J.
I would root right away, downgrade if necessary. RevoIt rom is incredibly fast and has bloat removed. We don't know how long until gingerbread so not worth waiting.

Sorry for double post. Best way to root is if your on VS910V6 is to downgrade (there is a tutorial on here somewhere) and use superoneclick 1.7 ragethecage. If VS910ZV4 is on your phone just use superoneclick regular root. Then you have to put on revotoolkit to put on cwm. There you can flash a new rom

Just extract the files, run the program, plug phone in and select internet mode with USB debugging enabled, select the "rageagainstthecage" exploit in the right hand side drop-down menu and click ROOT.
If it hangs (gets stuck) try checking and unchecking USB Debugging while the program is running and the phone is plugged in.
Thanks for the help so far. I have successfully downgraded and rooted.
I apologize in advance because I know all of these questions have been asked before but there are sooo many guides and youtube videos and forums. Some things might apply to the Revo and some might not.
Anyway...
1. I plan on installing revolt 1.5 but first think I should backup and save a copy of the Verizon Rom to be able to go back if all hell breaks loose or they update to GB. If I backup in clockworkmod, where does the backup go on the sd card? What is the name of the file? Should I take it off the sd and or put it on a computer for safe keeping?
2. Does "rom manger" work for the revolution? I asked me for phone model but didn't have the revo listed.
3. I installed Ti backup but already have the rom backed up. Is Ti backup used solely to backup apps?
4. The install instructions for revolt 1.5 say "make sure 4g is enabled," how do I do that?
5. The instructions do not say to wipe the cache. Is that no longer a required step?
6. Is there a "file manager" for accessing the sd card?
Too many ?'s, but thanks.
J.
In the same boat, sort of.
Was wondering if the sixaxis app for connecting a playstation controller to our phone works. was gonna root my phone this weekend and if this app works with our phone maybe ill stay up a little later tomorrow to see if i can get it working lol.
Thanks for any reply

1. I'm pretty sure backups go to external/clockworkmod/backups
But you don't need to make backups for this since you can always flash the rooted stock ROM.
2.ROM manager does not work.
3.titanium backs up only apps and there data (I like mybackup pro more)
4. If you didn't change any settings 4g you'll be fine.
5. Always wipe cache and dalvik cache. May take time to boot up but its.normal .
6. Es file explorer or root explorer

Need a little help...

I went and rooted my droid 4, and without knowing about safestrap, i started backing up and deleting apps with the free version of Titanium Backup. I now have a couple of apps that will not restore back into place, and i am unable to perform the upgrade. Since then, i have installed safestrap, and attempted to flash the rom at http://forum.xda-developers.com/showthread.php?t=1508341, but all i do is bootloop on my safe system. Any idea what i can do to fix the unsafe side so i can apply the 219 update? Am i kinda out of luck until the fastboot files are released?
try asking here
http://forum.xda-developers.com/forumdisplay.php?f=565
this forum is nearly dead, like 5 people a day visit here, very few people have a droid 4
i wish i could help more, but im not very good at this, but there are more people there that could help
What I'd do is download the stock recovery files that Hashcode has put up, and make sure you have anything you want backed up, and try advanced restore and flash all 3 options. As for the boot loop, did you try to clear cache and dalvik cache?
Are you referring to the [SAFESTRAP ROM] Stock MotoBlur 6.13.215 for Droid 4 at droidforums (forum won't let me post link) for hashcode's stock recovery? Or do you mean simply uninstalling the safestrap recovery from the safestrap app? I haven't played much with the stock recovery, so i'm not sure what 3 options you are referring to.
As far as the safe side, i wiped cache, wiped dalvik cache in the advanced menu, and done a factory reset... still bootloops...

I am having the same issue. I was recommended to unzip the stock rom posted and attempt either a direct or adb push install of those apk's that are missing. Someone did this one by one and was successful in installing the 219 update.
You could attempt to install the stock rom through safestrap to get the update. please make sure that you are at full 100% charge as most roms wont flash correctly with less. I recommend getting full charge and flashing while still plugged in.
Hey guys, so what exactly is going on? You are missing apks on your main system, and your safe system bootloops?
So, your primary system functions, it just is missing bloatware, preventing you from updating? I just want to be sure I understand before making a recommendation.
Welp, i got some good news, i got the main system fixed and then updated. I took a stock 215 rom, extracted the /system/app folder and the system/build.prop to the sd card. Then i simply copied the contents of that folder into the /system/app on the root of the system with a file manager (used estrong's, other file managers that support root should work.), copied the build.prop to /system, and then did the update OTA. I lost safestrap and root, but i was able to reroot with moto fail... i have not tried reinstalling safestrap yet, nor have i mess with the bloatware like i did last time.

I sort of did the same thing. I downloaded the rooted stock from and unzipped it. I then rebooted and manually tried to install the update and noted what files needed to be restored and then I coped them to dropbox then moved them to /system/app and it worked
I attempted to move the files but got an error when doing so saying I could not move them to the folder. The only file I seem to be getting the error with is backupassistantclient.apk but that might be because it is getting to that first and erroring out. Does Astro not support root to ove the files in /system, etc?

Why don't you just flash it back to stock instead of messing it up more. I got a thread up here on our to do that.

It is not listed in the "All Apps" section of the apps manager.
Symptoms: When my phone rings the notification to tell me who is calling does not pop up. I have to go into the phone app to even see who is calling, much less answer the call.
My notification bar is gone.
When I get a text message my phone will vibrate, but not chime.
My wall paper is gone.
I have found threads about rooted phones where people have removed the systemui that this are the same symptoms they have. The problem is that they had the original rooted program they used, so can reinstall that. I cannot do that, as my phone is not rooted. That is why I think my systemui is gone.
Install root explorer and check in /system/app folder for the apk, or in /preload/symlink/system/app. If it's there in preload, you will need to create a symlink for that in system/app.

You won't be able to install it as you're not rooted and it requires administrator privileges. But it's there anyway so I don't think that's the issue.

Thats really strange... Try rebooting into recovery (Vol up, home and power held down until you see samsung logo) then choose wipe cache and reboot. I doubt that will fix it though.
Only other options I can see are to root device by installing phillz kernel, wipe cache and dalvik from recovery, or root device, reinstall the app and make sure permissions are correct, or wipe device and start from scratch.

Stop playing with essential parts of your system if you have absolutely no idea of what you are doing.
To get back to a reliable configuration:
download a stock rom and install it following the instructions in Dr. Ketan's thread here.
After that: start to read and learn. High probability this will protect the life of your device.
