**Second...READ, READ, and READ AGAIN!**
***If you have rom manager premium, you will need to also download the free rom manager from the play store. The free version is needed for this method to work properly***
That being said, this is how to successfully sideload the ics leak:
Fastboot back to .173 using Matt's 1.51 utility here -> , or RSD. Root your phone using motofail (included in Matt's utility), and install OTA Rootkeeper app from the play store or Matt's utility. You need to be completely stock with no custom recovery EVER installed. You can't just delete bootstrap or safestrap. If you have them or have had them installed then rsd/fastboot back to pure clean stock 173!
Download the leak from this torrent here in Arcane's first post
Rename the .zip and the .crc file to Blur_Version.6.12.173.XT912.Verizon.en.US.zip and Blur_Version.6.12.173.XT912.Verizon.en.US.crc
Move them from your computer to your phone's sdcard or sdcard-ext.
Using es file explorer with "root explorer" and "mount file system" enabled in it's settings, copy both files to the root /cache folder (you can navigate quickly through es file explorer using the favorites button at the top. The root folder is the phone with / under it in favorites.
Download Rom Manager Free from the market, but do not install clockworkmod.
Go into the superuser app and update binaries.
Go to Voodoo OTA Rootkeeper app and protect root.
Go back to the /cache folder using es file explorer and tap on the .zip. It will give you a few options to open it with. Choose Rom Manager.
Rom Manager will open and prompt to click ok to reboot into recovery and flash. (It says it will boot into cwm and flash, but it goes to stock recovery)
This will reboot the phone into the stock recovery and flash it.
When ICS boots, go into the Voodoo Rootkeeper app and restore root. If it does not, then use the terminal method here
Failure to read and follow these steps will result in failure and frustration!
For those of you who WERE rooted & protected root with Voodoo, installed the ICS leak & subsequently lost root like I did, dhacker29 tweeted out some helpful instructions to remedy the issue!
I did not personally use this method - before it was available, I had already RSD'd. On my second time through the process, I successfully retained root. Therefore this was unneeded (for ME!) All credit goes to dhacker29, I just wrote up the in
