upon quiting farmanager you were doing fine ...but your phone wouldn't turn on why ???...simple ..because the break-in-loader that allowed you accessing the moblie's file system -using far -is still there ,lying , in the first part of the main phone's flash , so you need , to reflash , either rest file or the whole main file using Xs++..!
For sure, the Break-in-loader , has no purpose ,as it is , but in conjuction with farmanager would allow user to access his/her mobile's File system so as to Customize/Finalize..and even edit/add/suppress files and so on !
