Is there any way to use the omap4boot to send the infor to the phone? Since i cant send the phone into fastboot or software mode without omap4boot it seems to show that that program gets the phone into a more working state maybe it can also do the flashing? or a script to keep the phone in the software mode for longer than 2 minutes?
If you can figure out how to adapt this method and get it to work on the L9 this is probably your only hope -
Other than that you could try taking it to a service center and having them try an OctopusBox to repair it or go where you bought it and try to make a warrant claim.
I know it sucks but I think these are your only real options. I'm not sure about were you live but I can buy a brand new L9 right now for $30 from MetroPCS.
