for older hardware, there is still hidden direkt link
http://www.hantek.com/Product/DSO5000/DSO5202B_Firmware.zipwhere for new hardware, and that link is on Hantek's webpage, is
http://www.hantek.com/Product/DSO5000/DSO5202B_Firmware2.zipI use the first one, due to the fact that i have old hardware.
Hantek removed the old firmware link, because firmware password is the same, and people with new hardware have very often installed wrong version - which eventually destroyed their DSOs.
Of course one need on older hardware some libs installed, i do have actually dueal boot: MSO (with very special firmware from Hantek) and DSO (from the first link). For dueal boot i made simple script which checks unused button (probe check) to confirm boot, and F1 / F2 to select between MSO and DSO. Due to the fact that MSO and DSO are using complettly different FPGA designs, i have to boot twice - boot -> select platfrom -> boot again -> confirm, but that not a big deal knowing what necessary (when i reload FPGA design when FPGA is already running, I/O is not working properly).
So yeah, my Tekway (it actually Tekway DSO, with extra MSO PCB and LAN and and and) DSO is bit special, and i have to decrypt/copy files manually when updating, but it works.
For other models, like BMV with old hardware, one can use the firmware from first link, but again maually! SD and 2M point are working on my DSO as well, i did modified mainboard as well (bigger memory).
