Many of you know I've been rocking and recommending the .75 ICS leak for a month, it worked so well for me I saw no reason to upgrade to 211 ICS considering the effort involved. Unfortunately for folk like us, it's quite impossible to resist an upgrade staring you in the face, so I down/upgraded yesterday. Matt's 1.6 utility brought me to 181 with no problems, check for updates found and started downloading 211 OTA. Since no one seemed to have an issue rooting 211 with Matt's 1.7 utility, I did not voodoo.
Not a good choice, I could not root my device. Neither Matt's 1.7 or his 1.6 would root me. I spent a few hours yesterday and finally got my device rooted manually.
For the few of you who do have trouble with root, I automated the process.
Download the zip and extract all 8 files to the same folder. Connect your phone via USB, try it in MTP mode first. Open the folder and double click the "root211razr.bat" file. Let it run, phone will reboot 3 times, and come up rooted after the third boot. If the .bat file does not work, there is a txt file with the commands and directions for running the exploit manually, run each command and note which command causes an error, and what the error is.
Credit for this goes to Dan Rosenberg (@djrbliss), as I am only using the exploit he discovered, and to Matt for his utility that this is based on
