Droid 4 with no more root access still has a useless SU (Superuser) app

[Rocky]

Hi,

I would really like to regain root acces while avoiding to do a factory data reset. I seem to have (partially?) lost root access sometime shortly before receiving the OTA update to ICS. When I try the traditional one0click rooting process (which I did when it still had GB), it all seems to start off kinda normally, but then gives me some error codes where busybox and su apk are mentioned. Then, after rebooting the phone once or twice, the black screen closes and my phone remains just the same: unrooted and with the su app still in there, not granting any permissions to anyone.

Any help is very much appreciated.

It sounds similar to the problem I had when I OTA updated to ICS.

In the end, I had to fastboot the system partition, and then I could root normally.

All my personal data and settings were left intact.

Sorry I can't provide more details, but that was the first (and only) time I fastbooted, so I don't remember everything all that well. If you do some searches on these forums for fastbooting Droid 4 I'm sure you can find everything you need (after all, it's how I found what I needed).

Thanks a bunch for the tip, LocoRon; I'll definitely look into that. Hopefully that'll take care of this issue.

Best regards,

I almost missed your post, but am glad I didn't! I'll try that tool first and, if no luck, then the fastboot method. I really appreciate your help as well.

Cheers,

I don't know if you're still around; I was wondering if you had to do some sort of a backup of your settings (I'd love to do mine on Titanium Backup, but it needs root access, which I obviously don't have, although the SU app is still in my phone).

What I'd like to try with your tool is:

5. Unroot script - This will remove superuser, the su binary and busybox. However if you boot into recovery it will still indicate root or at least past root (qe display in recovery). Even a fastboot with data wipe will not reset this.

Since it says it'll remove the superuser app, which is what I can't get rid of in order to reroot.

I'm mainly trying to do as least as possible to get the job done, hoping to avoid messing up the phone.

But now that I see "5.", it reads, "Boot in Motorola Recovery"... so I'm not sure how will I go about accomplishing what I intend to accomplish.

Just try running the root again. It should work, will probably error on superuser already installed, but should still give you back root.

Unfortunately, I can't remember if I had to do a backup of my settings or not. I had already backed up my settings with TiB prior to the ICS OTA (and thus, before losing root functionality); I don't think I needed to restore them.

It's taking me forever to get this done. I hope you're still around. As of now I'm downloading an "ICS Fastboot" file (or whatever it is) that I found in these same forums (http://www.droidforums.net/forum/droid-4-roms/220480-ics-fastboot.html#post2231576). I just don't know exactly how do I go about using it once it's downloaded (it's taking a while). It would be really helpful you can share a little more.

You need rsd lite or you can use my ics lite tool.

I'm back after all this time. Thanks for your help.

I'm trying RSDLite with no luck (something's wrong), but I'll try to give your tool a try.

Thanks again.

Rocky, did Jsnweitzel's tool work?

I was closer to being done with the one you suggested, so I went all the way through.

Now the phone seems to be clean and fully stock (no more SU app, finally!) , but now the problem is I can't re-root...
