then ther is only one thing to do, if you have the 512kb file you must get a flash programmer that supports 29f400 and a psop44 adaptor, remove the ecu, open it ,remove with hot air station and program it with programmer. After that solder the flash again with original file.
This is what you need to do.
If you have acess to other tools such as eobd2 or kess ,etc (no kwp+ or kwp) try to use them.
Good luck!
