HELP Really messed up my G1

[phamous]

not so much info you're giving us here, but from the looks of it, you said you flashed the ota radio and Hard spl,

that means you should be able to flash modded roms. since you aren't able to, reflash the radio and spl, find the haykuro "death/danger" spl, flash it,

radio before spl,

and then try flashing the rom, if you still can't flash...

then it's a problem with the recovery image you're using,

you're goin to have to learn how to use adb/fastboot and push a recovery image into your phone, use amon_ra's it has a lot of built in scripts and features already in the menu and will make your life a lot easier down the road.

Now with a functioning spl and recovery , you should most definitely be able to flash roms. Wipe cache/data, and if you're using an ext partition, reformat that as well and then repair the ext filesystem. This ensures the cleanest install. Flash w.e rom after that and boot.
