He already did it asddasit, he wasn't asking if it would work.
Ok what you need to do is use the 1.50 winstaller:

To install the recovery files needed to downgrade back to 1.50 then upgrade back to 3.40OE-A and it should be fine. Unless you can get a copy of the 3.40OE-A flash0. Then you would just use that. But yea, either way will work. Just make sure to backup your flash0 next time which seems like everyone never does even though it's common sense XD. Also don't use theme flasher if you don't know what your doing since it seems every noob that uses it always semi-bricks. Maybe I should add that back to my sig. DON'T USE THEME FLASHER OR ANY AUTO FLASHING PROGRAMS! Just do it manually.
