Hey guys I am trying to root my Droid 4 from verizon wireless and I am having a problem doing it. A little info before I post what I am getting from the Command Promp. I am running this on my windows 7 64 bit laptop, I have all the drives updated and the cables find and recognize the phone, also I have tried running it in admin mode... The issue is it can't find a particular folder and I would like to somehow reinstall the folder without doing the factory reset and rooting the phone afterwards. I would like to just keep everything as is. Anyways here is what I got. Let me know what you think I should do in solving this issue. Thanks too all in advance

Thanks again for helping a fellow droid user

What OS is your phone running? 4.1.2? If so you need to use the Razr_blade root method as all the other/older methods no longer work.

Same dev (Dan Rosenberg) just newer method/exploit.

Yes I am using the 4.1.2 os. I will try and see if the Razr_blade root works.

So I have tried that method and this is what I got:

Where did you extract the .zip on your PC?

I did mine to the desktop and ran it from there.....you could also try unzipping to C:, it'll create the directory on your desktop or C: named razr_blade.

Double click to enter that folder and double click the run.bat file to execute it and then follow the directions that are displayed.

If you are running it without decompressing it it will fail.

rrr

Thanks for everyone's support and input on this topic. I have tried and re-tried and finally got the phone rooted. Once again thank you all for giving me advice.

I too have a rooting issue with my Droid 4 with JB installed:

I have been trying to root with the "DROID_4_Utility_Jellybean_XT894_WinMacLin.zip " package. I really like the time spent on the batch wrapper by mattlgroff and the great work of Mr. Rosenberg, but unfortunately, the rooting procedure has failed every time I've tried it.


Steps I've tried so far:
---------------------------------------------------------------
Un-installed the Moto Drivers.

Re-installed Moto Drivers "Motorola_End_User_Driver_Installation_5.9.0_32bit " from the zip package.

Removed all ">dev/null"s from script to be able to see the failure points.

Set up phone to "USB Debugging".

Set up USB connection to "Media Device"

Script result:
[*]

[*]
[*] Note: this will not work on Razr HD, Razr M, etc.

[*]
[*] Waiting for device...
[*] Device found.
[*] Phase one...
rm failed for 2, No such file or directory

The command that resulted in this failure in the script is:
adb shell "rm /data/dontpanic/apanic_console 2"

Obviously, the file 'apanic_console' is not present. It would seem that this script presumes you to have installed JB from either option one or two, prior to attempting rooting.

In probing the phone with {adb shell} commands, I cannot even list the contents of the {/data} folder:

Result:

shell@cdma_maserati:/ $ ls data
ls data
opendir failed, Permission denied

Set up USB connection to "Mass Storage"

Same script failure point, same failure message.

Tried different USB ports (no hubs, etc.), same result

Tried '-Settings > Apps > Smart Actions > Clear data', no help.

Tried running from desktop & C:\ same result.
I have also tried letting the script run to the end, thinking that the missing file/folder was just an anomaly, but the results are the same.. NO ROOT.

The Dev Mgr has no exclaimation points in yellow triangles for either configuration, so I believe that the computer can talk to the phone properly.

I have read much in the forums about similar failures, but this particular one seems to not have affected anyone else. My main failure occurs before any reboots, so the phone is certainly booted up and running properly.

Any help that anyone could provide in correcting this problem would be greatly appreciated.

its the old root method use razrblade found here http://vulnfactory.org/public/razr_blade.zip

Thanks for the reply, however..

The 'Run.bat' code for this method is the same as referenced in my post. It was just incorporated into a multi-purpose batch file to allow flashing a ROM, rooting and installing SafeStrap, all with one menu.

I am really puzzled that there isn't more info available for the D4 out there.

Any other suggestions? (Please!)

factory reset then follow the directions. its pretty clear. rooted mine and 3 others with the tool so it is user errors not the tool. if you can't do it it may be better that you don't root cause you can fowl up your phone.

I have tried a factory reset as well. My problem seems to be that ADB cannot gain access to the folders it needs to on the phone.

Even when I try to just list the files in '/data/' with ADB, I get a permission error.
Here is a capture from ADB:

adb shell
shell@cdma_maserati:/ $ cd data
shell@cdma_maserati:/data $ ls
opendir failed, Permission denied

If I try:

adb root

I get:

adbd cannot run as root in production builds

I can appreciate that you have rooted other devices, as have I over the years and that bricking the phone is possible. I can also appreciate that user error seems the likely explaination, BUT I assure you that I have followed all the directions as-written each time I've attempted this.

The trouble I seem to be having is access to key folders with ADB.
I certainly am not an Android developer, but I know my way around a CLI and if I cannot get access permissions to the proper folders, I sure won't be able to execute the scripts that depend on this access.

Since I haven't seen it mentioned in any of the discussions, I have not tried to use ADB to change the permissions of the '/data/' folder. Is this even an option? If a permission change is required for access, I can change it back to default-level permissions after the exploit is done. I just need a bit of guidance here.

I do greatly appreciate your replies and look forward to learning the error of my ways..

:question::question:

try this its an updated version
https://docs.google.com/file/d/0B_nizg6yUZ0NRjVTZlQ0d1hXVVU/edit?pli=1

Unfortunately, the binaries and scripts in this package match (file sizes down to the byte are the same for all) the binaries and scripts that I have been using.
Maybe I should backtrack a bit and give the complete history of the phone:

I recently bought this unit on eBay. The phone is in great condition and shows no signs of tampering by the previous owner. When I received it, the phone had been factory-reset, so I bypassed the initial screen with the 4-corner-tap method. I then checked 'About Phone' for the software version. I am assuming that the software update to 4.1.2 was OTA (but I have no evidence of this fact).
The WiFi & Bluetooth both operate normally. I have purchased a SIM card for the phone, but I have not installed it as yet, since I wanted to get the device rooted and personalized before I tried to activate it on my plan.

Next I began the research for D4 rooting with JB 4.1.2 and settled on the 'DROID_4_Utility_Jellybean_XT894_WinMacLin' by mattlgroff. After verifying that the rooting portion was the same code (& credit given) as Mr. Rosenberg, I executed the batch file. After it ran to completion, I used RootChecker to verify root access & found it was not rooted.

Next I altered the batch file to remove the redirects to 'dev/null' so I could follow the progress of the steps, which is when I discovered that it was failing access to the '/data' folder.

And so here we are.. stumped!

just do a factory reset just try the tool and stop reading into it so much. i just rooted one off of ebay 2 days ago with the last one.
it has a different run.bat https://docs.google.com/file/d/0B_nizg6yUZ0NRjVTZlQ0d1hXVVU/edit?pli=1

Great advice! I'm finally rooted.

Thanks for all your help!!
