[Motorola Droid RAZR] Ohmster:
Root Explorer comes up and offers the R/W mount, but does not work. See post below, the built in file manager really does allow mounting R/W and it works just fine. I am really bummed that ES File Explorer let me down.

Welder, I just went all through this, even installed Super SU. The mount R/W does not work. It gives me the choice box, I say ok, and nothing happens. I even use the built in crappy editor and if I try to change any system file, even just put a small mark, say a 1 in the comment field so as not to change the actual function of the file, I get "You need elevated privilege for this". Have you EVER done this or saw it work? In cm11? What build? I am on 04/12 and have problems all over the place. Never saw this feature so I cannot understand how or if it works. ...sigh.

Okay, I can enter the root folder, write a test file to it. No problem. So I have root. But mounting the system folder is NOT happening. Root or no root. Try it yourself, please, and see if it works for you.

/system/etc/permissions/platform.xml -rw--r--r--

You can open the file with R/W, and at the top are comments so they will not affect the file. Try to put a small change, put a 1 in the comment section, something small that will affect nothing, and then see if you can save the file. Please? You are the only one who knows what I am talking about, I need you to confirm. Thank you.

Really? Yes, it is there, just like you said. It gave me the mount R/W option and I took it, but funny thing, nothing changed or is different. I like to use Jota Pro + w/Root key and that cannot save. So I used the crappy built in editor and made the change. It is telling me I need elevated root privileges, try root explorer. I just did! Funny, this install does not have su in the app drawer, it is only build into the Settings menu. My cm11 builds always had su in the app drawer, it did say ES Explorer Granted Root Privileges, but I will be dammed if I can see it. Something is not right. You know, we always got an su app in the drawer, but now with it built in, the only access is through settings. Yet, my root privilege to mount R/W is not working, AT ALL. Says I need elevated privileges. How much more elevated than root can you get? Yeah, I need an su app to investigate this further. In the past, Titanium Backup always asked me to install Super SU. I have done it, Super SU tells me the binary is out of date, update it, I do, and it always fails. Yet su itself says it is fine. Grrrrrrrrrrrrrrr!

UPDATE:

I am getting orange bars off and on. I have no su app to check, only built into settings and it does not seem to work with everything like ES File Explorer. I am trying to install Super SU and have three apps ahead of it, downloading forever. Something smells rotten in Denmark...

Okay,downloads are going again, bars not orange anymore. Lets see if Super SU can shed some light on this. Either play store is super slow or my mobile data is shot, I should have rocket power speed with 4G. Rebooting. Speed test, then try Super SU install again.

Man, no orange, yet play store shows everything "waiting for network". Switch to WiFi and it starts again, finishes an app, and stops. I remember going through this with Verizon tech years ago. They had me go into apps, find play store and google services, I think. Wipe all the data and try again. If I recall, that fixed it. Might have to try it again. But that was back on Gingerbread. Oh, downloading again on WiFi. Speed test is good, 15 Mbps both ways pretty much. It has been as high as 30 so this is not a "data problem" but a Google problem.
