Here's the original thread.
[EXPERIMENTAL] MultiROM v11 (Touchscreen support) - Boot ROM from sdcard
All the important info and how-to-use instructions are in the first two posts of that thread.
If you like it, please go there and click on thanks for Tassadar.
I've given it over a week of testing between v10 and v11 and haven't found a single glitch myself.
So, here you go!
The ported recovery has a kernel compatible with either novatek or hitachi screens, if you're wondering
CWM-based MultiROM recovery for the Optimus V (flashable zip)
MultiRom v11 for the Optimus V
I'll post more info later (I'm short on time but said I'd get this uploaded today.)
all you really need to know to make it work is in the original thread. Just use these Optimus V files instead of the ones in Tasssadar's post.
I'll edit this and the second post later with more specific instructions.
FYI: This is not a ROM. This is a recovery, and flashable overlay for your boot.img which allow booting from roms on sd-ext or from internal memory.
Please read the original thread before using.
More later! Enjoy.

Don't blame me, or Tasssadar... Just take proper precautions. As the original thread says, BACKUP! Also, never flash a ROM and recovery at the same time, make sure the first works before you flash the second.
