Needs some help on goin BACK to factory

[inpherno3]

well i have had this phone for a reallly long time, its gone through quite a few cooks and is currently sitting on ttrans manilla 2d i think (i have since gotten the g1 and moved on but gave it to my girlfriend). Well its acting up pretty badly and i was wanting to format the sdcard, format the main phone itself and return back to WM6.1 with battery status installed to scale the processor and to make everything back working smoothly for her (including txt and mms since it hasnt been sending pictures now, not to mention a complete bug where she couldnt answer the phone for over a week due to the screen freezing and it needing the sliding to answer)

APN = T-Mobile

Phone = Tmobile "Wing"

(I know that 6.1 didnt come on the phone originally but i cannot seem to find any rom for it or the proper flashing procedure to revert it back without bricking it. Im almost positive its been hardspl'd but its been a while so im not sure)

If it's hardSPL'd, just followed the guidelines posted in the thread.
It has been posted before that if you use the tmobile NBH with USPL, it would bring the phone back to the default configuration. I have tried it myself and it worked fine, too.

ive looked for these threads and couldnt find them. Honestly not even sure what those two you mentioned are (sorry its been a while, been involved in the sapphire port to the g1)

So you've been involved with the H builds?
