Hardware occasionally goes through revisions that require different firmware codebases. This seemed to become much more common over the past few years of supply chain challenges, where manufacturers had to change components due to availability issues, which often required new firmware. With some vendors, firmware version 1.x only works with the original design, while 2.x only works with design #2, 3.x only works with design #3, and so on. For a recent example, you can check the threads here on the Uni-T UTi260B/690B thermal cameras. They are the same design but the UTi690B was commissioned for sale exclusively by Banggood, as a private-label model, and they are the support provider for that model (you won't find it on Uni-T's website). I have the UTi690B model and had a YouTuber send me the firmware update he received from Banggood that worked for his UTi690B. It bricked mine. So I contacted Banggood to see if they could help, and promptly send me the exact same firmware image that bricked my unit. Mine was a 1.x.x.x firmware model, and the version they're sending out to customers is 2.x.x.x. As I and others in that thread experienced, trying to flash a 2.x firmware to a 1.x unit renders it unbootable. Thanks to others in those threads, I was able to recover by opening it up and accessing the LVTTL UART pins to get a console shell that allowed me to manually copy back a 1.x firmware image. I let Banggood know that they were responsible for bricking 1.x customers units with this firmware, and they seemed surprised, saying that they'd be taking it up with Uni-T. I haven't heard back from them since. |

so they sent me a file to flash on there but with no instructions on how to do it. its not a normal .up or any other firmware file its a zip folder with all kinds of stuff in it. im trying to do some reading on it now but i wish they would have just sent me the normal firmware file would have taken 2 seconds to re flash. |

So a quick look in Ghidra revealed the passphrase: "hsa3g". Yeah, for both. Then no surprise if it bricks after accidentally updating with the wrong file. The update uses the same format to Hantek DSO2xxx series. I modified the build scripts, with this you can extract and build update packages :) It shouldn't be hard to figure out what to backup and create a restore package just like in the DSO2xxx. The update file from the thread does this: --- Code: ---echo "update start" rm -f /lib/firmware/*.bit cp /tmp/dmm_client/DMMCore /dso/app/ cp /tmp/dmm_client/dm65fpga_16.bit /lib/firmware/ cp /tmp/dmm_client/dm65fpga_21.bit /lib/firmware/ cp /tmp/dmm_client/libscpi.so.2.1.0 /lib/ cp /tmp/dmm_client/*.bin /dso/app/res/icon/ --- End code --- Attaching the scripts and both decrypted firmwares packages. |

so can I just flash the decrypted firmware? sorry very new to this part of things the person who sent it said just to flash that file but you can't flash it as it sits in the zipped folder |
| DavidAlfa:
No that's for research only. Why don't you simply use what Hantek sent to you? |
