i have an LG Optimus One. I really need help on a seems-to-be impossible repair.. I have NO MONEY, NO WARRANTY. Yet, my phone is fully bricked (cant turn on no matter what) the only 2 methods that would work to my knowledge is: Motherboard replacement, or JTAG. (both costs money which i dont have)

This is what caused brick:...: i used LG R&D test tool (like KDZ).
This program not only allows u to flash a firmware, it allows u to merge a DZ and a model.dll file together to create a flashable kdz.. sounds crazy but thats what i did. After this frightening message listed below, my phone hasnt booted on since (in any way):

21:14:17 : Launching SW update
21:14:17 : Unpacking KDZ
21:15:51 : KDZ file extraced
21:16:11 : Files were extracted.
21:16:11 : LGMobileDL Load.
21:16:11 : Port = -1
21:16:11 : Connecting to phone
21:16:21 : Check Phone mode = 1
21:16:38 : Phone type check.......
21:16:43 : LGMobileDL.DLL Loading....
21:16:43 : _SetAuthMark Fail
21:16:43 : AuthMark

 

can you give me directions toward ur updater? also, do u kno anybody that could JTAG my phone or how i could find a motherboard to swap?
