Help rooting Droid Razr 4.1.2?

[enkryptik]

Push works outside of adb shell though. At least did for myself and foxkat. Device offline is within adb shell

Not sure how to remount as RW. Something I just noticed, my /sdcard/ and /sdcard-ext/ are empty when connected. Thinking it has something to do with being connected as mass storage. Does it need to be in a different mode?

Pushing SU outside of shell gets me a permission denied error.

Here's what I have on the phone now. SU binary is 3.0.3.2, updating it now.Fails to gain root.

Did these commands

adb shell "su -c 'cp /system/bin/su /system/xbin/su'"
adb shell "su -c 'chmod 6755 /system/xbin/su'"
adb shell "su -c 'chmod 644 /system/app/Superuser.apk'"

Didn't help any, at this point I'm just punching in commands blindly. I sort of understand what the above commands will do. The next command in that utility calls for SU to be deleted out of /system/bin, thought that was odd. If I reboot and do a SU ID command it returns with a 0 but I still can't update my SU binary or any other actual root commands.

Going to lunch, I'll think more after I eat something.

Yeah I don't think you want mass storage mode. You should be able to push to SD card, not to system. One in adb shell, mount as read write with commands in this thread then cp from sdcard to system areas.

Got it. Turns out you can't be in Mass Storage mode when running the root fixer. http://www.batakang.com/ftp/DROID_RAZR/RestoreRoot.zip

Switched to MTP and ran FixRoot, problem solved!

Another question though, it installed SuperSU 0.99 instead of 3.1.1 regular SU. Should I keep SuperSU or the regular one? I'm not even sure about the difference.

entitlement_check for hotspot is value 66 now.

Not 66 on mine. And yes mass storage disconnects storage from phone while connected. Used to be a dual mount app awhile back. Not sure if it still works.

As far as su, unless something isn't working correctly, don't really need to change.

I assume you used Matt's batch? Cuz seems like my method doesn't work for everyone or perhaps I got lucky with mine.

Grabbed Superuser-3.1.3-arm-signed.zip from Superuser
extracted the su and superuser.apk to root of where adb.exe is.

Some of this you can possibly cut out but I was basically just trying different things til I got it to work plus i wanted the su and superuser.apk on root of sdcard incase needed again.

I'm on win 8 pro so I had to set it to run as admin for adb to even work.

commands:
adb shell
su
mount -o rw,remount -t yaffs1 /dev/block/system /system

adb push su /sdcard/
adb push superuser.apk /sdcard/
adb shell
su
cp /sdcard/su /system/bin/
cp /sdcard/superuser.apk /system/app/


Don't have to reboot I don't think but always best to so you don't have to set read-only on system again. check to see if you have root with root check basic or whatever app you want.

Let me know if it works for you. I'd even consider starting a remote session and trying it if anyone would be up for it.
I'm pretty sure that's all I had to do.

I got root by using the files you listed but running a slightly different set of commands. I initially thought that I did not have the su-backup file but while poking around I found it in the system folder (this is the most important piece!). I looked at Matt's script and stripped out the things that worked for me. I had thought earlier that even if you had a copy of the su-backup you still needed root to get it to work. I was wrong. Looking at the permission settings of su-backup in the system folder I noticed that the backup file has the same rights as the su file. So here are the commands that I used from Matt's script (some may not be needed but...) (fyi - I'm on Windows 7 Ultimate and ran Windows command prompt with administrator privileges: (for all instances of /system/su-backup you'll need to substitute where your copy of su-backup is - IE. if it's in /system/usr/ you'll use /system/usr/su-backup instead

adb kill-server > nul
adb start-server > nul
ping 1.1.1.1 -n 1 -w 500 > nul
adb wait-for-device devices > nul
adb shell "/system/su-backup -c 'mount -o rw,remount -t ext4 /dev/block/system /system'"
adb shell "/system/su-backup -c 'cp /system/su-backup /system/bin/su'"
adb shell "/system/su-backup -c 'chmod 6755 /system/bin/su'"

I then tested to see if I have su rights by going into adb shell and running "su":

adb shell
su

If you do not get any errors and just the shell prompt then that should mean that you have su rights. Then I did the following:

su -c 'cp /sdcard/su /system/xbin/su'
su -c 'cp /sdcard/Superuser.apk /system/app/Superuser.apk'
su -c 'chmod 6755 /system/xbin/su'
su -c 'chmod 644 /system/app/Superuser.apk' <----- I didn't do this but probably should
su -c 'rm /system/bin/su' <----- I didn't do this but probably should - some with more knowledge please let me know why this should be done - thx!
exit
exit
adb reboot

Or you can do it in the Windows Command line (dos prompt):

adb shell "su -c 'cp /sdcard/su /system/xbin/su'"
adb shell "su -c 'cp /sdcard/Superuser.apk /system/app/Superuser.apk'"
adb shell "su -c 'chmod 6755 /system/xbin/su'"
adb shell "su -c 'chmod 644 /system/app/Superuser.apk'"
adb shell "su -c 'rm /system/bin/su'"
adb reboot


After rebooting I ran my voodoo OTA and it asked for superuser rights and in voodoo it says that I have root and root privileges.

Hope this helps!!!

EDIT: Forgot to add that I copied the files su and Superuser.apk using ES Explorer to the root of my internal sdcard. Oh, and "Thanks" Matt!!!

If you guys are having issue restoring root, you should use this tool made by Mattlgroff:

Windows: http://batakang.com/ftp/DROID_RAZR/RestoreRoot.zip
Linux: http://batakang.com/ftp/DROID_RAZR/RestoreRootLinux.zip
Mac: http://batakang.com/ftp/DROID_RAZR/RestoreRootMac.zip

If you read through some of the posts you'll find that we did but it didn't work. However, using pieces of his scripts does fix the issue so that's why we've stripped out only the commands that worked for us - along with slight modifications when needed.

Ah gotchya, didn't read all that.

the only thing I did was download the superuser.apk and su to desktop and move them to the folder adb is in.Then ran the commands
adb shell
su if you don't get the # sign here it will not work.
exit
exit
adb push su /sdcard/
adb push superuser.apk /sdcard/
adb shell
su
cp /sdcard/su /system/bin/
cp /sdcard/superuser.apk /system/app/
then rebooted, ran voodoo and it asked for su permissions.then ran root check to make sure and all was good.
I'm not sure if this will work for anyone else.That's just what I did,but all apps that need root permissions are working and android tether is working.

Will the Windows version of RestoreRoot work even if I wiped my Root when I tried to Fastboot Restore 6.16.211 again in Droid RAZR Utility 1.82? I was 1/2 rooted after I flashed JB but now no Root at all!!:angry:
