| Upgrading the Hantek DSO4072C and DS4104C oscilloscopes bandwidth up to 250MHz |

Hi. New here. Don't know if this is where I should post this question. Was considering buying a 80Mhz Hantek DPO6082P scope and was wondering if this series is also hackable to the DPO6202P with 200mhz bandwidth? Or perhaps just stick with the older 200Mhz DSO 5202P model? |

Hi all I had a look to several contributions in this post and really appreciate the high quality of discussion. I am wondering if someone can help me - bought a bricked voltcraft dso-1084e with an obviously corrupted NAND and would need the full NAND content as .bin file to be able to flash over JTAG...Recovery with F2 and F3 not successful and UART serial connection shows messages that some NAND sectors are bad.... Please help 😁 thx |

Have you tried to contact Hantek's support already? They will send you a recover file to restore the device. |

Hi Microcheap, Thank you for your reply! I contacted Hantek and indeed they sent me a (full?) firmware file (kernel.bin, uboot.bin, root.ubi, recover.ubi, params.bin, kernel_bk) with an uboot.exe tool to be copied on a SD card and make it bootable. This process requires windows xp (tool doesn't work on newer OS even not windows 7, I tried). That's why it took me some time to get the SD card set up properly. Then you need to put it in the SD card holder of the pcb. Bridging (shortening) two vias on the PCB causes the board to boot from the SD card and the NAND gets flashed from the SD content. The programming can be monitored on putty via the UART output. The tool gave me update success, then I removed the shortening bridge & SD card and did a reboot of the scope. And then.....guess what 😷🤐😲💩 Nothing works anymore. Screen is blanked out, lights on the frontpanel are on, and no message / no control anymore via the serial interface. USB dead. And this although the script was running through without error. I sent the log back to Hantek, let's see if they can help me further on this. What I observed is that the tool obviously did not erase the NAND before programming, maybe it works only in production on a "fresh" NAND? Would not be an issue for me to replace it with a new one... And what I learned from this - probably it would habe been better to flash root.ubi via usb and keep the uboot sector untouched, I think my scope would still show some signs of life then.... Keep you updated... Franz |

The recover process per SD boot card was successful now. Scope is operational again. Used a different slower SDHC card and bang.....After the removal of the shortening cable the scope booted from NAND as if nothing had happened. Good that I had saved a backup of the /config/cali.dat file before, because this is the original calibration data of the machine. So after the recovery I copied this file over to the machine. Self calibration went smoothly, tested and all ok now. If you need a full recovery of the firmware this is a very easy methode. Only tradeoff is that you need a computer with Windows XP to prepare the SD card. All the required binary / ubi files, a "uboot.exe" program and a short manual how to do the update was part of a package I got from Hantek support. Contact them if you need the software, they are really helpful and respond witin a day or so! |
