cat /sdcard/su > su

I am using the PRS complete rooting guide. And when it tells me to type cat /sdcard/su > su, i am getting this error message - cat: can't open '/sdcard/su': No such file or directory.
Can anyone help with this?

Do you have su on your sdcard?

use unrevoked. one click root

just use the one click method by unrevoleved its easier

Su is not on the SD card. The sd card is a brand new PNY card. I have Su in the sdk/tools folder.

Then obviously, that command will not work. Use the unrevoked method if you are unsure what these commands do/how they work. Less headache on your end.

where is it located?

maybe i'm missing something obvious, but why pipe the text rather than just copy the file?
Sorry if this is the wrong place, but that command is curious.

This is what it's asking me to do.
From PRS Complete Rooting Guide
Now type the following commands to make it persistent through reboot
Code:
adb shell
su
export PATH=$PATH:/system/bin
cd /system/app
cat /sdcard/Superuser.apk > Superuser.apk
cd /system/bin
cat /sdcard/su > su
ln -s /system/bin/su /system/xbin/su /* IF YOU GET AN ERROR HERE DO rm /system/xbin/su THEN REDO */
chmod 06755 su

I don't know what that guide does, but it doesn't seem right --- it'll mess up the privs, that's why the old root was written as an update-payload.
It's redirected I/O since you can't copy across filesystem boundaries -- ie /sdcard to a different mountpoint.

So if I reboot my phone now, do you think I'll lose root and have to start over?

Either way, it shouldn't matter much. If it didn't work or you lost root for any reason, just go to http://unrevoked.com/ and click on the image for the Incredible. Today unrevoked released version 3 of their tool. This will root your phone and flash the custom recovery all without your needing to do anything in a shell.

AND - if you appreciate unREVoked's work - please donate. They do amazing work and they do it all for free! We're the lucky ones to have such [email protected] developers out there who do this kind of stuff so that we don't have to figure out the exact second to push in our SD cards, push files to the SD card, and then push them to the phone at exactly the right time...... just download, run, and you're done.

Just use the unrevoked 3 you will save plenty of pain and struggle

unrevoked3 worked! Thanks for the help guys.

No problem were glad to be of assistance

adb commands nexus one-read only error

I have been trying for some time now,pushing files via adb commands onto nexus one but keep getting cannot copy file read only file error.I am fully rooted and unlocked.I have also reinstalled the android sdk but always get the same error when I push the image file.has anyone experienced this with their phone. I have a feeling its something to do with the SD card but can't be sure.any help would be appreciated. Thanks.
I know you must be thinking "Jedi"how can he can he call himself an androidjedi when he can't sort this simple problem (to some of you),but I must say even a Jedi needs to learn!

try adb remount before your command

Dunno if this will help but have tried changing the system to rw then try to push

Tried that no cigar

are you trying to push it into your sdcard or the phone system??
and remember the whole folder name has to be in the push so it woul have to look like
C:\Users\Android>ad push "C:\Users\Android\Downloads\Android\Nexus 1\Phone.apk" /sdcard/files
has to have full path of where you are pushing it from/too.. i have mine sdk setup to use adb in any directory as well why you dont see it in the sdk directory

@ilostchild
Thanks i will try that later today and let you know
As for pushing the file - i am trying to push it to the sd card - but i am not really sure as i am following instructions in the [HOW-TO] Revert HBOOT 0.35.0017 to 0.33.0012 thread in the forum
as i need to downgrade my Hboot from #17 to 12
are the commands different for pushing a file to the phone?

the more i think about i think i need to flash the file to the phone - but i will try your adb command format of specifying the location of the file in the comp

Ooo you want to push to sdcard.. ok then yea, you would type it like this
C:\android-sdk-windows\tools> adb push C:\Users\Android\Downloads\Android\signed-passion-FRF50-from-
ERE27.1e519a24.zip /sdcard*
if you dont have the option to use adb in any directory, then you have to be in the android sdk directory and in tools
cd android-sd-windows
cd tools
adb push(drag the file you want to push in the command prompt window) /sdcard*
sorry i know its detailed and im sure you know all these things.. but it kinda gets the questions out of the way for future problems to come

BusyBoX

I have busybox 1.6 on my captivate i see on www.busybox.net 1.17.3 is out. I have downloaded it from the site and its a tar file with a folder with a whole bunch of folders and files. How do you install this?

Are you familiar with the phrase, "if it isn't broken, don't fix it?"
I advise you to heed its warning.
But if you must proceed, a quick google search for "how to install busybox manually" brings up this very good result: http://www.droidforums.net/forum/droid-2-hacks/82573-busybox-manual-install-how-guide.html
Edit: By the way, love the avatar. Great album.

Yes i understand if its not broke don't try to fix it but i'm a OCD updater! Would there be any advantages of updating it? P.S. I saw Megadeth and Slayer a month ago they rocked!

Only advantages I can see are having a couple more bug fixes and maybe 4-5 new commands built in.

Download Busybox-1.17.2 HERE
Extract busybox to your SD Card
Make sure you are in PC Mode and Debugging is enabled in Applications options
adb shell
su
stop
mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
cp /sdcard/busybox /system/xbin/
cd system/xbin
busybox --install /system/xbin/
mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system
sync
reboot
You can also use Root Explorer or whatever file browser you may use to copy busybox to your system/xbin folder. Some people use system/bin but I prefer xbin...just a habbit.

Click to collapse
Ya, I read that and got really scared.
What is PC mode and where do you type these commands? (Vista user)

Ok, figured out how to type in the commands and stuff, but I get stuck on the "cp /sdcard/busybox /system/xbin/" part, I get "cp: not found" I tried lookin up other methods and I keep getting stuck at the same part - trying to move the folder to the xbin folder. adb push gives me the same error - adb: not found.
any help would be appreciated.

Are you rooted? If your answer is yes, just download Busybox from the market and let the app do the installing for you.

Brilliant! Sooo much easier, but I'm not NAND unlocked, I'm z4rooted so it wouldn't install. Tomorrow I'll see if I can root through NAND.
I'll break you yet AT&T!

I think you're seriously confused. The Captivate isn't a NAND locked phone. Generally when you root, busybox is installed. (I think. At least it always was for me.) You could also try installing Titanium Backup and have that install busybox for you.

Root instructions...

If you followed the directions exactly on a version 4 phone, this should work no problem.

Links to the necessary files are listed at the bottom.
Remember, I am not at fault if you brick your phone, now, proceed.
Connect your phone in charge only mode to install the LG Bootstrapper and drivers, or grab the LG Universal Drivers.
Change your USB Mode to Internet Connection
Go into Settings/Applications/Development and ensure USB Debugging is turned on
If all goes according to plan, you should see the ADB Ladybug icon in your notification bar
I updated the Rootzwiki page with the same info found below.
Busybox actually comes installed by LG on the Revo, how awesome is that??
Download the rageagainstthecage binary
Download the SU binary
Move these files to the same directory your adb.exe is in.
Code:
The > and # characters below illustrate the prompt
you should have, if you have the $ when you go into adb shell,
exit out and type 'adb usb' then go back into adb shell and
you should see the #
Open Command prompt (either use the Windows Key+R and type cmd or start/run, then type cmd)
32-bit users: >cd c:\program files\android\android-sdk\platform-tools
64-bit users: >cd c:\program files (x86)\android\android-sdk\platform-tools
Or >cd (whatever directory adb is in)
>adb devices (verifies you are connected)
>adb push rageagainstthecage-arm5.bin /data/local/temp/rage
(if the above command fails due to read-only, type 'adb usb' then 'adb root' to validate root status, then 'adb devices' again to verify connection)
>adb push su /data/local/temp/su
>adb shell chmod 777 /data/local/temp/rage
>adb shell ./data/local/temp/rage
>adb shell (If this gives you a $ prompt instead of a # prompt, type 'su', if that fails, 'exit', 'adb usb' like above.)
#mount -o remount,rw -t ext3 /dev/mmcblk0p12 /system
#busybox cp /data/local/temp/su /system/bin/su
#chmod 6755 /system/bin/su
Verify the file is in place w/correct permissions
#cd /system/bin
#ls -l *su
After the ls command you should see the following returned by the system:
-rwsr-sr-x root root 26248 2011-05-29 01:09 su
At this point, you may way to remove the files you put in /data/local/temp (optional):
#rm /data/local/temp/su
#rm /data/local/temp/rage
continue with commands
#reboot
Download and install SuperUser from the Market

Just a note for some. The rageagainstthecage bin file may be detected as a virus/trojan. It is not. You may want to disable your antivirus before downloading the .bin file.
I run avira on my desktop and it caught the file as a virus everytime I downloaded it and then deleted it. Avast on my laptop however did not.
Root is simple if you follow the instructions. You need to make sure that adb recognizes your device. Takes 5 minutes to complete, took me longer to install adb again and update it.

No idea. I have not used the one click. Create a thread for it. I posted what I know which is adb.

Successfully Rooted
with RootzWiki instructions for Windows, needed the remount and busybox lines to overcome the permission denied when pushing su.

Hey guys, either using S1C or ADB Commands, have we found out if it's possible to unroot this as long as you Nand Backup the stock rom then unroot from there yet? Just because I got this phone as a filler/4g unl. lock and got buyback on it from best buy so I could buy a dual/quad later on when they come out .

Doing a factory reset I believe will unroot you. There is no nand back up at this time. We are waiting for a recovery mod.

Oh ya I know, I just always keep a stock one, on the Inc if you factory reset from an AOSP rom, you'd bootloop, so you had to make sure you were on a Sense 1.0 or stock rom(from my experience), so I was just making sure it was no big deal to go back.
Any idea when we will have cw on this?

If you have to return your device, simply remove the superuser app, after you unfreeze anything you may have frozen then factory reset. They honestly will never know it was rooted. The only way now that you can really tell is the super user app from market.

Just so everyone knows. SuperOneClick can root and unroot this phone ok.

Cool thanks for checking. Any benefits for ADB over S1C? Can't wait to finally root and freeze half these apps. I think we need a few more twitters to praise koush for a recovery on this beast.

No No, I was saying we need to praise Koush's good work so he will make one faster .
And Stetsonaw, any idea if I root through ADB, can I unroot with S1C, since it uses the same idea.
S1C for whatever reason will not run(tried three computers, a XP, Vista, and Win7 lol), it keeps freezing at the same spot, everytime.

Should be able to, since S1C does what the ADB method does... or you could just delete the 'su' file out of /system/bin and /system/xbin (if it's there) to unroot.
EDIT: I couldn't get S1C to open on my desktop, and my laptop, which would open the program, would bluescreen when i connected the phone, so i had no choice but to do it the ADB way.

Hmmm, ya now my computer for whatever reason won't open up ADB through command. This is getting irritating lol. Should be nice and simple, but it just won't go through. If I downloaded the SDK Manager like 4 months ago, it shouldn't matter, correct?

make sure you change directory to wherever your adb.exe is located... as in:
Code:
cd C:\Program Files\Android\android-sdk-windows\platform-tools

[Q] rooting new thread as I can't get answers and nothing makes sense, vrgh

I tried to follow these instructions, first it says ''Neither ADB nor the SDK need to be installed as all needed files are included in the attachments below (though it won't hurt anything if they are).'' but when you go to the video it says '' Be sure to install ADB on your computer first!''
I have installed it but thats confusing information to begin with right there.
I have installed ADB and downloaded the files, putting the SDK file in C: drive, now it gets confusing....
I have run the Qemu program and it hangs at ''Daemon Started Successfully''
Nothing happens from this point onwards, I've looked around and asked but receive no answers, so I do more googling and find this - http://www.androidpolice.com/2012/09/17/amazon-kindle-fire-hd-7-already-rooted-heres-how-to-do-it/ ...........
this seems ok instructions but I have no clue what to do with these instructions!
''After you download the file, extract the contents and pull SU from /system/bin/ and SuperUser.apk from /system/app/ and put them in the directory you'll be working from''
!! DIRECTORY??? COME AGAIN!???
After that, execute the following commands:
adb shell
rm -r /data/local/tmp
ln -s /data/ /data/local/tmp
exit
adb reboot
adb shell
echo 'ro.kernel.qemu=1' > /data/local.prop
exit
abd reboot
adb shell mount -o remount,rw /system
adb push su /system/xbin/su
adb shell
chown 0.0 /system/xbin/su
chmod 06755 /system/xbin/su
rm /data/local.prop
exit
adb reboot
adb install Superuser.apk
!! VERY GOOD BUT HOW AND WHERE !!
Anybody care to translate these confusing conflicting nonsense instructions please?
Yes I'm well aware I will be wrong with some of my statements.
I need and idiots guide as it were.
Please reply with helpful comments guys, cheers
I should mention I tried following the video instructions but there is a great big picture of a KFHD in the middle of the screen and the quality is so bad you can not make out what is being type in the command prompt.....

Revkyle.com did a video with step by step instructions, that is what I used and worked fine.
