Hey Guys, Finally got around to hacking my oscilloscope (DS2072A) and it went well, I have enabled 300MHz bandwidth with all options. I decided to document my process with a good amount of detail and have created a PDF. I recommend anyone who would like to hack their to view this. I had to upload the file elsewhere because of the 2mb imposed on us my eevblog. The document was generated from information collected from this thread, thanks to all those whom contributed. If there are any recommendations/revisions for the document let me know. All the Best. - Please view revised post on page 204 - |

OK, I flashed my DS2102A with Zombie28's hacked FW. I verified that it had flashed because the system now shows that version 00.02.01 is loaded and it was 00.02.00 before. When I run Ultra Sigma and do the *IDN? query, I get: -> *IDN? <- (Return Count:50) RIGOL TECHNOLOGIES,DS2102A,DS2D15xxxxxxx,00.02.01 I tried reflashing and was very careful to use the correct DS2000update.gel file. Same result. This is the same behavior I saw before with my original un-hacked FW. I'm not getting the long string for the key as expected. Huh? Any ideas? What am I doing wrong? |

Re: My prior post just above. I tried re-flashing a third time (same hacked FW file) and this time I got the key string in Ultra Sigma. Strange. On the prior two attempts I noticed that my free option trials had vanished. Upon rebooting after this third flash, the welcome screen showed my trials again. |
| GlassFET:
OK, success! 300MHz+ all options. A thanks to all the smart people who made this possible! A question: I understand that I may still flash new FW without losing these options. But, if I keep Zombie28's FW in the scope, will it perform identically to regular 00.02.01.00.03 FW? In other words, any reason to replace the FW with un-hacked FW? I don't want to tempt fate... |
