Hi everyone. I just modified DS1000ZUpdate.GEL file 00.04.03.01.05 (04.03 SP1) to 00.04.03.02.03 (04.03 SP2, current installed shit)... :phew: Here is what happened: 1. Same software version detected. Update?... :scared: 2. Reading Gel file... :scared: 3. Analysing Gel file... :scared: 4. Update was failured. Please, check your flash driver and the update file, then try again!... :rant: :wtf: :-- fkers. |

I might be totally wrong about this though - too early to say... |

Well, not THAT easy. The version number is repeated in each file header as Uint32. So all of them have to be changed, too. I will add a mechanism to my application where you can change the version to the one of another .GEL file by opening it. This should be reasonably safe . |

Files not the problem I think, so not that easy too. Something is now in the footer. Actually I took DS1000Z(ARM)Update_00.04.03.01.05 and have DS1000Z(ARM)Update_00.04.03.02.03 Now I look footers and DS1000Z(ARM)Update_00.04.03.01.05 footer second half from 80 to FF is the same as DS1000Z(ARM)Update_00_04_04_00_07 footer. ??? Somebody must look into APP. I can't read it. |
