No im using safetrap 2.0
Disable safe mode..If safestrap is installed but safemode isn't on, you can upgrade just fine, but its always best to uninstall it.
You probably need to do a fresh install from scratch...Use 1.6 tool, then the unstuck method.
On your /mnt/sdcard there is a folder called "safestrap" open that folder up and there are 2 more folders, "orig" and "safe" Copy the contents of the "safe" folder to your external SD card. You don't really have to do this, as rolling back to 181 doesn't wipe your internal SD card, but its better to be safe than sorry.
Do the full method to upgrade your phone to 211, make sure everything works, then verify that your internal SD card is intact, if so go into the safestrap folder (NOT the folder on your sdcard-ext) open the sub folder called "orig" and delete the file, verify contents in the "safe" folder.
Install safestrap, launch it, enable safemode and it will backup the image of your working 211 and restore whatever ROM you had running safe side with all data, etc.
I have been switching between KOA and .2xx so often to keep them both updated I am not even bother to use normal backup anymore (well, I make 1 bootstrap every week or so, since I am kinda paranoid )
