Default PPC6600 and QPST, changing MSL, or does anyone read Chinese?
I tried to reprogram my ancient Harrier (PPC6600) using QPST, and discovered this can't be done via USB. I guess it is just too old. Google searching reveals there is no DMRouter.exe or ##DIAG# on the Harrier, and it doesn't matter because no version of DMRouter.exe copied to it works anyway.

My primary objective is I want to set MSL to 000000 for use on Verizon. My old Sprint PPC6600 has a bad ESN for Sprint, but for some reason it has a valid ESN on Verizon. Verizon's OTA programming requires MSL set to 000000. Is there any way to set this other than using QPST?

Also, I found on a Chinese website that QPST only works via serial. 3rd post down on this thread explains how. Only problem is it's a Chinese forum:

Google translation looks like this:

Block 9 holes buy a serial port, connected to GND, RXD, TXD on it. Of course, you have a data base, that is the kind of data port can xv6600 Next take out all the lines that. Most of the USB interface data cable in order to save costs, did not take the RXD, TXD. Can be bought on Taobao. I was there bought.
I don't understand what "Block 9 holes" means, or "Of course, you have a data base". Would anyone who can read Chinese translate any better?
I already tried using a USB-to-TTL serial dongle and connecting GND to GND, RXD to TXD and TXD to RXD, but QPST still didn't see it. I even tried RXD to RXD and TXD to TXD in case I got the pins reversed, but that didn't work either. I used a TTL-level dongle because I read here http://pinouts.ru/PDA/pda_wallaby_pinout.shtml that the serial is TTL level. Do I need to pull DCD up? Is ActiveSync required to detect the device via serial for QPST to work?
