I was new to TB Pro prior to applying this update. I had many apps frozen but did NOT unfreeze them before applying the update. The update went 100% smooth and no issues.

Are we sure that unfreezing is necessary? Maybe only if the update is OTA initialized and not updating manually using recover?

Anyone, feel free to chime in and give your thoughts.

I followed the instructions in the Development Thread by Omniuni and it worked like a charm. I was rooted with Safestrap installed. Backed up Root with Voodoo, unfroze my apps. Installed update from SD and voila. Restored my root with voodoo.

I don't believe this can be applied to your safe-system. I'm fairly certain it has to be applied to your primary system. I asked earlier if the update could be carried over, my primary is on .219 but my safe-system is on .215 and I don't have a solution.

Lost root after OTA update
Hey guys,

I downloaded the OTA (yes OTA not manual) update last week for the soak test. I accepted the OTA update while rooted (and I had safestrap).

My problem is that now my device is not rooted (although i still have superuser.apk). Also, mattlgroff's droid 4 utility will not grant me root either even though it says root successful. Here is what the utility displays.

Motorola universal root script

Tested on Droid 3, Droid Bionic, Droid RAZR, and Droid 4

Before continuing, ensure USB debugging is enabled, that your
device is in charge only mode, and your phone is connected via USB.

Safestrap does not work either... so just do a factory reset?

This did not work. I did a factory reset and re-ran the exploit with no luck. I still have superuser.apk in my system/app folder which is read only with a modified date of 2-10-2012 (when i originally rooted my phone). So, I did a factory reset and still no root? Any other ideas?

When I try this:

adb push su /system/bin

I get failed to copy 'su' to '/system/bin/su' : Read-only file system

So, the exploit is not working. So, does this mean Motorola updated something to prevent our root method from working in this latest release, or is this a result of me updating while rooted? I want to say the former, since the exploit is unable to get write access (my superuser.apk modified date is 2-10-2012)
