BSI went to boot mode , normal till here , after got the backup made by FVDI in "my documents" , i try to restore as i did couple times in the past,
[special functions--ecu flasher--JCI 2008-] , BUT , funny comes now , with the original backup i get WRONG CHECKSUM , with some old backup files, with different Signature , write good .
