Let's clarify:
1. What partitions/files did you modify, other than recovery? Flashing an incompatible recovery should really NOT cause any damage to your normal boot...
2. How did you flash recovery?
Was it by using any of the provided rooting apps, and then running dd
commands via adb, or you used a firehose loader to flash in EDL mode? In
the latter case, you already have the correct loader, then I assume you are
looking for a full (firehose) read to re-flash all required partitions...
