Firmware update R211 released for SanDisk Extreme SSD

I am trying to get my bootable usb drive (or any other drive for that matter - tried others) to boot my laptop and install firmware r211 from r201.  Boot screen just stops after a few lines of code with no further action.  I have to turn off the computer and reselect boot from hardisk (SSD Extreme 240gb).  Disk still reads firmware version r201.

Used the latest version TooKit downloaded from SanDisk to configure my USB et al.

I have an ACER Aspire 1830T, Intel dual core I7, with 8gb ram.

Thanks for any advice on what I may be doing wrong.
