every time i use this code in adb
adb shell
cd /dev/block
dd if=/dev/block/bml3 of=/sdcard/bml3.bak
copy to sdcard / upload
i get a "/dev/block/blm3: cannot open for read: permission denied"
what did i do wrong? my phone is unock i have a app called superuser and busybox
Thanks in advance
Type "su" first. You need super user permission, i.e. your phone must be rooted.
i tried that it gives me the error after
cd /dev/block
Edit: i just spamed the code and now it work but i gives me error "cannot open for read: no such file or directory"
Edit: when i use the su command i get a permission denied error. and everything afterwords. i have the superuser app and the busybox app i used the one - click rogram to unlock my samsung galaxy s i9000m from bell. i also updated to the latest firmware could that be the issue? it seems like i can look into the file(using astro file manager) and see that the file exists but i cant read or write to it.
ahh seems like superuser wasnt updated to 2.3.3 .... got it thanks man
From your phone, not adb, try:
Code:
su
dd if=/dev/block/bml3 of=/sdcard/bml3.bak
Then connect your phone to your PC and copy bml3.bak manually.
ok, so i tried to get help in the actual froyo 2.2.13 install thread but i'm not getting an answer.
i downloaded, installed, and it said it was successful.. i rebooted, went into the settings to see if it changed, and it still said 2.2.9. i tried to do it again and now my phone will not reboot into recovery using droid x bootstrap or rom manager... won't even go into it if i do it manually... i tried to uninstall bootstrap and rom manager and reinstalling, no luck. please help.

Try these comands from :
AllDroid Public Board»Motorola»Droid X Forums»Droid X Rooting»How to get 2.2, Rooted, on your Droid X
under:
If you have /system/xbin/su and /system/app/Superuser.apk, but cannot use "Superuser" (no prompts from Superuser app, "permission denied" when you try to run "su"), just do the following:
Run "adb shell"
Run "/system/xbin/su"
Watch your screen for Superuser app to prompt for permission and click "allow"
Run "mount -o remount,rw /dev/block/system /system"
Run "cp /system/xbin/su /system/bin/su"
Run "chmod 4755 /system/bin/su"
Open the SuperUser application on the phone (app launcher) and make sure that "superuser" isn't listed and denied. If so, "forget it" and return to step 2. If you can't find SuperUser, it's not installed and you should download from this posts attachments and "adb install Superuser.apk"
[optional] Run "mount -o remount,ro /dev/block/system /system"
This should help you get your su working again.
not sure on your process so if you still do not have the .13 I would go back to your process and see what you are missing. I rebooted into recovery from bootstrap when I installed mine. Then I had to do the above commands to get my su back.
If you still don't have it, try the FULL instructions from here:
MDW Presents: Droid X 2.3.13 - The Froyo Upgrade
read through it and see if #5 from step 2 pertains to you.
The biggest thing to remember is to mount before you select the file to load on your sd card.
This thread:
Motorola Droid 2Droid 2 Android DevelopmentHow to root the Droid 2
will also be helpful regarding root if you have further questions.
Hope this helps.
My su is working fine. Nothing is being denied when I open it. Just cannot get to recovery with any option... im lost...

Maybe just double check through adb shell even if you are not having su issues?
Run "adb shell"
Run "/system/xbin/su"
Watch your screen for Superuser app to prompt for permission and click "allow" (I never saw any request)
Run "mount -o remount,rw /dev/block/system /system"
Run "cp /system/xbin/su /system/bin/su"
Run "chmod 4755 /system/bin/su"
I had similar issues of nothing being denied after a successful install and had to do the su commands. It helped me to reboot into recovery afterwards.

I saw your post in the other thread. The best thing you can do is go through the links I gave you. Start with the root thread and click the more directions link in it. read through the processes and make sure you download all files and also understand what sbf is. Once you have all of the tools to do root and load whatever leak or rom you want you should be set. Understanding what is going on is key. This is a decision you are making to alter your phone for your benefit. Take the time to download SDK and whatever else is needed for your computer. Become familiar with what shell is and how to get there as well as explore within it. If you can get shell down and how to access your su and run commands, you should know enough to start. There are many things you need to research in order to be confident in what you are doing. I am sure you will not have a problem, just putting the time in to figure out everything is key. This is what I had to do.
I think that this is the best advice I can give you. None of us can know exactly what you are doing so you need to know the processes and choose which one is going to work for your circumstance. Good luck and if you have anymore problems I am sure all of us on xda can figure out a solution for you.
ok, finally, with a little help i got my phone rerooted and back to normal. learned a lot in the process too. thanks to all...
edit---
solved. close please. had to allow su access on my phone when i typed su in the cmd prompt LOL i feel stupid. i watched the video on theunlockr website but it was blocked by my adblocker and i didnt know it was there until i read a comment saying something about a video ._.
edit--
sorry
Hi, so im new to this stuff. i followed theunlockr guide to rooting the g1 with androot and got that done fine.
Now I've moved to flashing a custom recovery and I placed the flash_image and the recovery.img on the root of my sdcard and went to terminal typed su and all that good stuff. and it just says flash_image not found or something. so i tried the adb method and all is good, i type su and when as im typing the "mount -o,exec...." all of a sudden it just says Permission denied when I haven't even pressed enter.
And now I'm stuck...what could I do to solve this problem? Do I not have su access in adb?

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
I've been trying to figure this out all day and I'm stumped.
My stock Droid recently failed to get past the bootloader.
I'm following the directions from the CM Wiki titled "Motorola Droid: Full Update Guide" (no direct link because of my new account, sorry) and others I've found and they all seem to be exactly the same.
I've got SPRecovery installed no problem and after I run the update.zip I get a successful install message, including "enjoy your root".
The problem is in the next step where I ADB it doesn't appear I actually have root access.
I think this may be because I'm connecting to my phone from the SPRecovery menu, but I'm not sure.
This is what my cmd screen looks like when I try to follow the steps under "Installing ClockworkMod Recovery" > "Second Method (manual method)".
Code:
C:\Users\XXXX>adb shell
/ # su
su
/system/bin/sh: su: not found
I noticed that in SPRecovery there are "mount options", so I tried mounting /system and trying again and I get basically the same thing, but without the "/" and without the directory
Code:
C:\Users\XXXX>adb shell
# su
su
su: not found
I'm not Linux savvy enough to know the difference unfortunately. I've tried 3 different update.zip from 3 different sources, but all appear to be the exact same thing.
Typing "busybox" in the ADB shell kicks back all the functions so it appears to be installed.
"adb devices" kicks back "040388990E0EDITED recovery"
Any ideas would be greatly appreciated, it's getting very frustrating.
Do you have the opportunity to root your phone from the Recovery-Menu?
I have OpenRecovery (OR) and when I boot in OR i can manually chose to root my phone.
----wrong----

I'm about 99% certain that is false. If it was that easy, I would have heard about it. Plus the only SU app on the market states " Grant and manage Superuser rights for your phone. This app requires that you already have root.."
