Upgrading the Hantek DSO4072C and DS4104C oscilloscopes bandwidth up to 250MHz
vladsol:
Which pins\testpoints must be shorted on the DSO4102C PCB to force sd card boot?
mdanh2002:
A few weeks ago I hacked by Rigol DS1054Z to 100MGz, GW-INSTEK GDS1054B to 300MHz and Hantek DSO4084C to 250MHz and used a function generator to measure the 3dB point of these oscilloscopes after the hack. Long story short, after taking into account measurement inaccuracies, I considered the upgrade to 100MHz for the Rigol DS1054Z (official bandwidth: 50MHz) and to 250MHz for the Hantek DSO4084C (official bandwidth: 80MHz) has been successful. The upgrade to 300MHz for the GW-INSTEK GDS1054B is in no doubt a failure, in so far as the 3dB point is at only 100MHz, and not at 300MHz, had the upgrade been successful.
But it's quality not quantity that counts. During my tests, the Rigol DS1054Z can still display 600MHz input signals (albeit at a very low amplitude), which can't be discerned from noises on the Hantek. Measurements on the Hantek are also much less accurate compared with the other two oscilloscopes.

Hello,
I own a kkmoon DSO4102s which obviously is a Hantek DSO4102C. The installed SW-Version is 3.50.0(181203.0) and the HW-Version is 1020xffffa000.
Unfortunately Kkmoon does not have any firmware update for this model and the support do not response at all.
Does anybody know if I can update as well using the Hantek firmware?
As the next step, I would like to make the BW upgrade but I do not find a tool for the DSO4102C to make a firmware backup.
I have seen how "Microcheap" did the upgrade with the 4072C and I have read the guideline from "W1ZZT3XX" for upgrading the DSO4xx4BC. (by the way, thank you so much for sharing)
Does anybody know if I can use the tool nandbackup_V2 for my scope?
or would the method from "W1ZZT3XX" do the job? (UNIX Shell =>"Type cp /config/root/system.inf /config/root/system.infBackup in order to create a local backup file.")
Thank you very much in advance for yor help.
Mario
