This was steps, that I was done, to successful hack my Rigol DS1052E scope (HW58 ver2.06) to DS1102E.
1. be sure that your USB key is working with Rigol scope (I use empty 1GB PQI FAT16).
2. be sure that your Rigol scope has proper USB connection with your PC (my OS is WinXP SP3) and there are installed all needed files, see details on page 1.
3. put put RGL update file from "Downgrade_2.06.00.01_to_2.02SP2" folder on USB key (I use file from page 61).
4. let Rigol do the update of the firmware (in fact this is downgrade).
5. remove the USB key, verify that the update was done successful eg. by measuring and playing around the scope, check the connection with PC.
6. ON/OFF your scope, if all seems OK, start rigupgr.exe (shafri's tool, from page 61) and patch.
7. ON/OFF your scope, check the model (you will se now DS1102E) on start.
8. put RGL update file from "Upgrade_to_2.04sp1" folder on empty USB key, do the update of firmware (I use file from page 61. and I use noproblem version 2.04), there are reports that it's no good to go on orig. version (2.06).
9. do the scope calibration (steps in user manual) and enjoy your 100MHz scope.
My question: Does anybody try with success to do the hack on 58 HW, 2.06 and after downgrade and changing model going back on 2.06?
