its best off not to flash to stock first... see, be it a custom ROM or a shipped ROM, there is still data being transfered throughout the flash. flashing a stock rom only adds an extra step to the flashing instructions i posted way back and on a new thread even... and it can add its own files which may corrupt some cache within the NAND, meaning that another flash with battery removal would be necessary to release these corrupted files which cannot be overwritten from within Windows[Mobile]...

flashing means transfering files (some files of which can be fractions of kilobytes in size even)... during the flash process, it is possible to not fully flash the rom because the old ROM (Read Only Memory) cache files cannot be replaced with the new ones, due to the old ones being -besides old- corrupted (broken) and stuck...after flashing a new ROM, and taking out the battery, this depletes (kills) any +-ionization (electrical currency) within the device since it does not have a CMOS Battery (a button cell battery which goes inside Computers to keep the clock accurate and certain hardware settings which cannot be controlled from an Operating System... An example of an OS is Windows, also Linux... etc...)after all the power has been released from the device the NAND then has no place to store its old ROM data, the device then routes what it can [unneeded crap] to the RAM (Random Access Memory). every time that there is no direct power (no battery and no USB connection to PC or wall charger), the RAM is released to be never again seen. ROM, however is stored into firmware. Firmware is neither hardware (like a video card, keyboard, monitor) etc, nor is it software (programs, games, drivers) it is pretty much a software that is permanent into the hardware's chip to enable its functionality.

thats as english as i can put it down... i dont know how else to explain it... you either understand or you dont...
nonetheless I know that this is a good thing to do before using your phone with its newly flashed ROM. it prevents countless errors over time
