[Q] Help on rooting

Sorry for making you read this if I made a nooby mistake.
So I rooted my Slide, and flashed the Eng-release to it. When I use ROM Manager to install the CM6 onto it, I can't get past touching reboot into Clockwork Recovery. I already flashed the Clowckwork into it (I think; you just need to push the Flash ClockworkMod Recovery button right?), but when I push the reboot into it button, nothing happens.
I tried the Fix Permissions button, and it says "An error occurred while attempting to run privileged commands!" That means that the app doesn't have root access, right? How do I give the app root access? I tried two superuser apps, one from the Market and one from this website, the one with a Ninja. When I choose preferences on the superuser app, it just hangs until I get the Force Close error.
How do I grant my app root access? I know I rooted my Slide because when I connect it to my phone and use adb shell, the pound sing comes up.

What method did you use? Did the phone have the 1.35 OTA Update?
Try this: download terminal emulator from the market, its free.
Turn on: you will see a "$" symbol type "su" (w/o qoutes)
if you see this "#" you are rooted..
Im sure there are easier other ways to check, thats just what I do. I know you didn't install the rom, so don't worry about that yet.
Chances are you arent rooted, I dont what adb shell would say, since I didnt have to use it directly, I just used my windows cmd prompt.

After looking at the other post a few below this one about the exact same problem that I had, I did what he did and copied the update.zip to my phone and booted into recovery. Thanks for the help, though I'm ok now.
Btw, I did have the terminal, and it did have the # sing

Getting Started [Update 12/23 - OTA Update Install fix for root]

[Update 12/23] For those of you unable to install the new system update, I've found a solution -- scroll down to the update! I AM NOT RESPONSIBLE FOR ANY DAMAGES THAT MAY OCCUR!
So I figured I'd at least get things started - Credit goes to whomever first tried z4root on their Droid Pro - and to mahst687 for the deodexing.
Lets Begin!
Resources:
Motorola ADB Driver
Android SDK
xUltimate V2.2.2
(Can't post links apparently, sorry -- googles your friend!)
#1 Root:
As seen on numerous android sites already, root is obtainable via z4root in the market. It may not work the first, second, or even third time -- just keep trying, it works I promise.
#2 Bootstrap and Clockwork Recovery
Download and install 'Rom Manager' from the Market. Once installed flash the Droid2 Clockwork Recovery. After flashing, obtain the Droid2 Bootstrapper and install it. Confirm Clockwork Recovery works by booting to recovery via Bootstrap.
#2 Deodex:
Download Android SDK for ADB, as well as the Motorola ADB Drivers posted above. Second, download xUltimate - also posted above. Once everything is downloaded and installed we're ready to begin.
1. Run Main in the xUltimate package - if the ADB drivers installed successfully you should be greeted with a menu containing several options - great!
2. Next run option 1.
3. Run option 2.
3. Run option 3 - sit back and relax for a bit
4. Once option 3 is done doing its thing, navigate to the xUltimate folder, more specifically the "origi_frame", and delete guava.odex
5. Run option 4 - it'll be a short wait
6. Exit the xUltimate
7. Enable USB Mass Storage on the phone and transfer both "done_app", and "done_frame" to the ROOT of the SD card.
8. Once both folders have transferred disable USB Storage, but keep the phone plugged in via USB.
9. Open up a command prompt and browse to the android SDK Tools folder (or where ever your ADB executable is located).
10. Enter the following commands:
Code:
adb shell
su
stop
mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
cp /sdcard/done_app/* /system/app/
cp /sdcard/done_frame/* /system/framework/
rm /system/app/*.odex
rm /system/framework/*.odex
mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system
reboot
11. If all went well your phone should reboot - which may take a few minutes. Enjoy!
[Update]12/23/2010
For those of you unable to get the new Droid Pro OTA working I have found a solution! You will need:
1)Root
2)Clockwork Recovery
3)System.img from update
4)Current Nandroid backup of your phone
5)ADB drivers and ASDK
So lets begin.
1)Boot into Clockwork recovery and create a backup of your phone.
2)Once complete, mount the phone as USB storage and pull the system.img file from the nandroid backup folder, as well as the nandroid.md5 (KEEP THESE FILES SAFE!!!!!)
3)Obtain the system.img file from here (Compliments of whoopsiedaisy).
4)Replace the system.img file in the Nandroid backup folder on your PHONE.
5)ADB into your phone (preferably still in recovery) and do the following:
Code:
adb shell
# cd /sdcard/clockworkmod/backup/2010-xx-xx.xx.xx.xx
# rm nandroid.md5
# md5sum *img > nandroid.md5
6)If all goes will it should create a new MD5 checksum file utilizing the new system.img
7)Go to the 'backup and restore' menu in Clockwork, and select 'Advanced Restore'
8)Select the correct nandroid backup folder where the new system.img file is located, and then select 'Restore System'
9)Assuming all goes well, go to Settings, About and check your new system version!

Nice, can't wait to try this on my wifes phone after work.

Is the second step necessary if you just want root access so you can install Wireless tether, etc?

Not at all. Simply run z4 if all you require is root access (and a host of apps like Wireless Tether, DroCap, Titanium Backup ...)

Can you please post the quickoffice apk from the Dpro so I can put on an DX? Same would go for the software that allows me to Invite attendees to meetings using GAL. It be copasetic if you can.

Thanks a ton! Freaking worked flawlessly on my Droid X.

Cool. Cant wait to try this on my wife's phone.

I downloaded everything you said and i started my deodex but when i select option 3 in main it tells me "error no odex file" have i done something wrong please advise

Is it really that simple?
I feel like I must be missing something. I just download an app from the market and reboot and I'm rooted?
Also, what is the deodex for? I want to root my phone to install the apps I want and I want wifi tether. Do I need it?
Also, I really want to understand what is going on under the hood, but I don't know where to start. Is there a 'for dummies' tutorial somewhere that I can go to to start understanding what all of this stuff is, so I can make informed decisions for myself about what I want instead of begging for help on internet forums? Thanks in advance for any suggestions.

Yes, Z4Root app allows you to root, re-root, and UNroot.

You'll only see the unroot button once you've rooted. Otherwise, it will first show only the "root" option.

I was rooted. I had titanium installed and superuser. Z4 ran fine but I had an old version of it. I dont know if that matters but thats all I did. I downloaded the 1.3 version and I now have the unroot button. On the old version there was no option for temp root either. Just root. On the version I have now there is a temp root and perm root button.

Would just like to let people know that your method for "updating" via nandroid backup would not work for me. Followed all the instructions to the letter and during the advanced restore I continually received md5sum mismatch errors.
So I took the chance and updated through the OTA update, it installed fine but lost root. Ran z4root (twice) and gained root access again .
Looking forward to some real custom daily driver roms for this guy.

Kinda new to the whole rooting thing, just got a new Pro and rooted successfully with z4root, got rid of bloatware and installed titanium backup, wifi tether, etc. Am I correct in reading your post that I can unroot, OTA update, and re-root again? If so, will I have to uninstall bloatware again, or reinstall root apps? Or any other repeats? Any danger in doing this?

No need to un-root. This update is for the system portion only and does not touch the userdata. I simply went ahead on the rooted phone, let the OTA update download and install. In doing so lost root, but had no trouble gaining root access again via z4root. Did not have to re-remove any of the bloatware, at least if I remember correctly. Root apps will not need to be reinstalled but you may need to re-give them permission for root access. No danger that I have noticed or can think of.

For anyone doing the update the android method....
For it to work
You must do the adb "new" md5 creation portion with your phone in clockwork recovery for it to work and to not receive the mismatch error...
To do this, reboot recovery... then plug in usb from your computer... during the phone boot into recovery you should hear the alert from your computer that something from usb was plugged in. Finally, use the mount option in recovery to mount sd card to be able to transfer the .img file over to the correct directory then unmount sd card and do the adb commands in terminal window...
I had the same mismatch errors using my windows 7 machine and creating the md5 with android booted
Hope this helps

Gfree_Verify Not Working, Not Sure if Root Worked

I followed all the steps from the Wiki: (http://forum.xda-developers.com/wiki/index.php?title=HTC_Vision#Rooting_the_Vision_.28G2.2FDZ.29_and_DHD).
Now the problem is when I go to verify the root. On the Wiki, where it says run "su' in computer ADB shell, I get access denied. When I run "./gfree_verify" in computer ADB shell, I get
Error: Could not open modem device; /dev/****
Error: Verify could not initialize device
But in my apps on the G2 I see an icon for superuser permissions. So did the root take or not?
Thanks for any help, new to Android.

Go in to terminal on your phone and type SU
After pressing enter if it says permissions denied, you have no root, if a Su message pops up click allow... that means you have root
Edit: I think you have no root

After typing Su in the terminal on the phone, I get a message pop that says either allow or deny. I click allow and it gives me root permission.

Then it`s OK!
After reboot/or try again,open terminal emulator on your phone and type "su".
If you get a superuser prompt, you have root!
After "su" you should see a line with "#".

After a reboot (two actually) after I enter su into terminal I dont get the popup anymore asking allow or deny. I get "#." I actually went through the whole rooting Wiki steps again, to root the phone (just cause I wasn't sure if I was rooted). Same results, the gfree-verfiy doesnt work and neither does the "older" method. But I get "#" after entering su in terminal on G2.
I also installed Rom Manager, I clicked Flash ClockworkMod Recovery and then chose Backup Current ROM. It asked for superuser permissions and I allowed it. It rebooted the phone and went to a ClockworkMod Recovery screen where I selected reboot device. Does this mean I backed up my current Tmobile ROM?
Another question, is it okay to delete the files I had to push to /data/local to root? How would I delete them?
I want to really thank you guys for all the help.

# sign means your rooted or have su access.
Go under manage and restore backups in rom manager, you should have a copy of the rom you just backed up. Unless you renamed the back up its probably a date.
Its ok to delete the files you pushed to data/local use a file manager like root explorer.

If you choose "Backup ROM" you phone boot into Recovery,then you have
to choose "backup/restore option to backup you current ROM.
Otherwise you don`t have a backup

Again thanks guys.
Now i downloaded Astro and ES file Managers but I cant find the files. Do I need specifically need root manager? Im guessing the ones I downloaded cant access root files.

You should really have posted up in the existing thread about gfree on this, or otherwise in the Q&A forum
But anyway, yes, those file managers don't handle root. Well, ES does have an option to do so, but it doesn't work on the Vision. So you'll need a root-capable file manager, as joemm said.
On the backup, that sounds a bit odd, but you'll know that it's doing a backup because it'll take a while. You'll get a different screen where it shows you it's backup up the main phone partitions, and even which file is being backed up. When it's done, make sure you copy this backup somewhere else, like your PC (i.e. so you don't just have a single copy, in case something happens to it - e.g. corrupt SD card).

Thanks to everyone who provided insight. I had the same problem and was worried about bricking my phone, but this worked and I'm happily rooted!

Superuser just won' work!

I rooted my kindle fire using kindle fire utility 0.9.6 (after the rooting superuser wasn't installed on my kindle), downloaded twrp, flashed hashcode jelly bean ROM from this link
http://forum.xda-developers.com/showthread.php?t=1766829
and then flashed Superuser-3.1.3-x86-signed.zip which I downloaded from this link
http://androidsu.com/superuser/
but superuser won't work, when I check the root explorer in ES file explorer it tells me that this feature can't work on ur phone
Please I'm really dying out here
Someone Help Pleeeeeeeeeeeeeeeeeease !!!!!

You need the su binary installed as well. But with that being said, why don't you just install the Superuser.apk?
[Edit:] It's late and I'm not paying attention for some reason. Custom ROMs come pre-rooted and you have Jelly Bean installed. Perhaps there's a problem with ES File Explorer?

Thank you for replying so fast
how can I install su binary? and about the superuser.apk isn't that what i flashed into my device i have a superuser icon on my desktop but it just won't add any apps to its list.
Thanks again

At the Superuser website, there are three zip files. One is Superuser, one is the su binary, and the other should be both. Not that it matters at this point.

I too used the KFU to supposedly root my KF, but when I tried to install Titanium Backup, it gave me the same error message saying that my phone did not have root privileges... I wonder if there is something not installing correctly when using KFU...

"Root" consists of the su binary, which the system uses to give the user root permissions, and Superuser.apk, which keeps a database of what programs you allow to have those permissions. With "su" only, you will still have root permission, but only at the level of command line interface and your apps will not be allowed root permissions. Superuser.apk by itself is worthless. Custom ROMS come pre-rooted so the need to re-root is usually unnecessary unless something happens to one of the above mentioned programs. The only way to be sure if/which one is missing is in recovery via the command line because custom recovery will provide temporary root access.
Code:
adb shell ls /system/xbin
...look for su
Code:
adb shell ls /system/app
...look for Superuser.apk
Superuser can be installed from within the ROM using the .apk (at least in earlier versions it was possible), or in recovery using the command line or by flashing the signed .zip from the superuser website . The su binary can only be installed while in recovery.
Of course it all can be fixed by re-flashing your custom ROM.
It may also be necessary to rename the check-rooted executable, but only if you're running the stock Amazon software.
I think that pretty much covers it.

Ok, I have a dumb question, but from where do you run the DOS commands from? (ie. what directory?)..
c:\KFU?

Right-click on your KFU folder and select properties to find the folder's path. It may be different depending on wherever you've installed it.

Thanks. but not sure i understand.
Here is what I'm attempting to do.. using the root method described here: http://forum.xda-developers.com/showthread.php?t=1638452 under "Getting to fastboot mode" there are a series of command line examples that seem to start with adb.... (ex. adb shell chmod 755 /data/local/tmp/fbmode).
Under Rooting the stock software, the first step command line is "adb shell mount system"
my question is from where do I start (directory) so that when I enter these commands they work?
Or are you saying that I need to fun all these from the KFU directory? (or KFU/tools) or some other directory..
I appreciate the help and feedback..

:h my::
Wherever adb is...Right-click on that folder to find it's path so you can "cd" or change directories to it. Alternatively, you can Shift + Right-click on that folder and select something like "Open command window here".

Rooting Hell Since 4.2.1

So I usually use the toolkit to root, in fact I have been for many versions now.
However with the installation of 4.2.1 I haven't been able to root at all. I use the toolkit in the same way but it simply doesn't root the phone.
So today I tried the manual way. I downloaded and installed SDK tools from google navigated to the adb folder and went through the commands. Everything seemed to go okay apart from when I typed adb shell chmod 06755 /system/bin/su. The command window did nothing.
I carried on and typed adb shell chmod 06755 /system/app/Superuser.apk, when it said "bad command" or something similar.
Rebooted the phone, no root... still.
However the Superuser app is there. So:
1) How do I delete the superuser app, bearing in mind it has system permissions. I'd like to simply start again.
2) I don't have CW recovery installed and would prefer not to bother with it if I can.
3) Just to confirm, when I root the phone, does that allow me to delete files in the /system/app folder?
4) Following this guide on rooting manually. Is that all alright?
5) In a couple of sentences, can someone explain rooting to me? From what I understood, rooting simply opens up the phone to allow access to everywhere, where you can copy and delete files, or apks.
6) If 5 is true, when following the rooting guide (4), which command am I actually telling the system to run as root? Is it simply the "root" command?
7) If 6 is true, how come when I re-boot, the phone won't let me delete things from the system/app folder?
Thanks for any help.

1) stop using a toolkit, and no you didnt root the manual way.
2) download this: http://forum.xda-developers.com/showthread.php?t=1538053 - its supersu, superuser is unreliable on 4.2+
3) fastboot flash a recovery
4) flash the supersu.zip
5) done.

Sorry, I should have explained the Su app is SuperSU.
Just gave it another go using a manual toolkit but still no root access. I also now have an su.apk, superuser.apk (SuperSU) and a su file. Need to delete them all.
What do you mean by "fastboot flash a recovery"? You mean flash a new recovery centre like CW?
Don't these superuser apps just manage app permissions? They don't actually enable the root access do they?
Thanks

Quick Q...
If I flash a 4.2.1 system.img to the phone, it will replace what exactly?
I'm thinking this might be a way to get rid of the root apps which are protected and allow me to update to 4.2.2, THEN look at manually rooting.

If I flash a 4.2.1 system.img to the phone, it will replace what exactly?
I'm thinking this might be a way to get rid of the root apps which are protected and allow me to update to 4.2.2, THEN look at manually rooting.
Click to expand...
Click to collapse
it replaces anything in /system... basically the OS.
