(Also, the encryption routines can be copied out and reversed, and somewhere has got to be the private key.) They could make life difficult by employing obfuscation, self-decrypting code, anti-debugging, and etc. They could disable/remove debugging support from the hardware, encrypt the firmware and embed decryption in the CPU, pot the whole thing, and require units to be sent in for firmware upgrades... :-DD Bottom line: It's hackable. Period. Get over it. Let the popularity boost sales and capture market share, bump up prices accordingly, and sell lotsa hardware. Heck, open source the thing, and let the hacker community develop advanced features and bug fixes. Let the staff coders focus on new products, and assign one to "manage" the open source project. |

--- Quote from: Wall-E on January 02, 2014, 07:43:39 pm ---Re. DP832 Power Supply Does the 1.03c Keygen still work on the DP832? I understand that 1. Firmware 01.06.00 should be installed, 2. Install the keys, and then 3. Upgrade the firmware to 01.08.00. Does this still work Ok? I seem to recall that someone said they lost everything including the metering accuracy. Is there anything to this, and if so, can it be prevented? Thank you for assistance, Wallie --- End quote --- Wallie, I think there's been a couple questions asked regarding the DP832 and using the Keygen, but it appears no one has the answer. I've been following this thread since the beginning and my head is starting to spin - :scared: As a summary to the thread, the DS2000 non A models: HW 1 upgradable (but someone has voiced issues regarding the 300Mhz mod causing issues, so stick to 200Mhz as the max bandwidth upgrade) - 50 Ohm Option doesn't work, HW 2 is upgradable to 300Mhz - 50 Ohm option is working. The DS2000 A models are currently not hackable but zombie28 is looking close to solving that. As for the DP832, I seem to remember someone stating the keygen is working, but just a few pages ago someone also said they lost the ADC accuracy (or something like that) after using the keys to upgrade, I'm holding out until someone confirms the key gen isn't causing issues on the DP832. Edit: Well this thread is becoming a monster - I have checked back in the thread an can't find any confirmation of the 50 ohm termination option on the HW version 2 non-A, so I may be wrong there.

i thought 300 Mhz is "buggy" on all devices... |
