Will this work on bbs01b?

[mariusver]

Hi,
I've googled the whole Web and cannot really find an answer. I have a bbs01b and would like to flash the firmware.
I used the stc programming software, it seems the chip in my bbs01 is compatible (STC15F2K60S2). But I am a bit scared to try it, as there seems to be no way back to reflash the original bbs01 firmware. I used to flash firmwares on mys tsdz2b, but it was quite easy to backup the old one.
Anyway, impressive work, it's impressive how you guys are able to reverse engineer all of this.
