CDMA User can ignore this!
I only faced this Problem by using the Stock based GSM Patch on an Stock based CDMA Rom (Eclipse / Simplex / Black Widow 214)

1. Wipe Data/Cache/Dalvik Cache
2. Install GSM Patch
Fastboot for the webtop_signed
Here's an way to get the second System running on an RazR that you purchased with ICS preinstalled. It seems, that you can't mount the Partition with it.
You will get an
when you enter the line
mount -t ext3 /dev/block/webtop /tmp/webtop
To get it working, we tried to fastboot an GB webtop_signed on an ICS Maxx and after that it works flawless for the Guy.
You also can use this to get your Files back which where deleted to get the second system running!
This is the
that was used to get on the
some times ago.
If you have an GB 2.3.6 Fastboot File of your Region and wanna use this webtop_signed, you can only download the FlashME.bat and add your File into the Folder!
After you downloaded an extracted the

In this you'll find the

Your RazR will reboot after the flash was sucessfull
Now you can follow the steps to get your second system on your preinstalled ICS.
8. I stuck in an Bootloop, what now?
In case, that your Rom won't boot you can always boot into the Custom Recovery again.
Shut down your RazR by holding
Power & Vol-
till your screen turns black. When you now start your RazR again, you should see the green Android from above.

Once you're there you can restore the Backup of your previous Rom!

If that won't work, remember the start of this Thread. You got RSD and the Fastboot Files ready, right?

10. Flash in Recovery
Of course you can still flash an Rom or Extras OldSchool - Like in the Recovery
Read the Instructions
of the Thread, where you get your Rom from! In most cases the following steps are needed:

2. Install zip package
3. Change zip file location > Micro SD
4. Install a zip package
