i know michael has put the instructions for firmware upgrade at his website. however, i cant't get beyond the 3rd step, i.e. how to select device LPC1115/303 ?

1. get the SwissMicros Firmware Update Tool as an EXE or zipped or get FlashMagic
2. install CP2102 driver under Windows, get it from here or here
3. select device LPC1115/303 (or LPC1114/301 for calculators sold before June 2012)
4. choose correct COM port
5. set baud rate to 115200 or lower
6. select interface: none (ISP)
7. Oscillator (MHz): 12
8. check 'Erase all Flash+Code Rd Prot'
in the menu bar at the top of the FlashMagic screen, under "Options->Advanced Options->Hardware Config" check the box in front of "Use DTR and RTS to control RST and ISP pin"
9. connect the calculator with a standard miniUSB cable, preferably a shielded one. The calculator may be turned on or off before flashing
push and hold the PGM button through the right-hand pinhole on the backside with a needle and press Start to flash the firmware. the PGM button may be released after flashing has started
after flashing is done, push the RESET button through the left-hand pinhole on the backside

I would appreciate it very much if some one could guide me thru the firmware upgrade process.

Thanks!
