charged it for at least 6-7 hours...hooked it up to computer...phone won't turn on...tried up+x+power button...get bootloader screen...flashing low battery, can't program...thought about getting big hammer...so what do i try now?
UP+Power gets you to bootloader.
X+Power gets you recovery screen.
UP+X+Power still loads bootloader.
If you can get to the recovery, you
probably don't need to use rsdlite. Instead, download a stable rom from your computer and you can mount your sd card from recovery and copy it there to flash it.
To do this (from clockworkmod recovery):
-select 'partitions menu' > 'mount /sdcard'
[Copy .zip from computer to sdcard]
-(still in 'partitions menu') select 'unmount /sdcard'
-go back to main recovery menu [power button]
-select 'install zip from sdcard'
-select 'choose zip from sdcard'
-find the .zip file and confirm the install

If you aren't able to get into recovery with X+Power, then you most likely will need to rsdlite a new recovery image, but will still want a stable ROM to flash afterwards, since it sounds like your backups may be 'flawed'.
