| Hantek DSO1152S - Wont boot after firmware update |

I was running the ver 2.01.1(140212.0) firmware previously. Thank you for your efforts, tinhead. I strongly suspect that the problem was hardware related at this end, rather than with any of your work. Your analysis and discussions of Hantek hardware and firmware have been totally outstanding! Should I start shopping around for one of those little USB to TTL interfaces? I only have a USB to RS-232 variety right now, which I know is not electrically compatible. Thanks! |

i did tested everything i could test, but without success. The only way is now to work over UART. I will of course guide you as soon you bought/build such adapter. Sorry for that. |

I have a USB to TTL-serial interface on order. When I have the hardware set up, I'll drop back into this thread. Thanks so much! |

Greetings! The USB to TTL uart interface arrived today and I got it hooked up. When I started the scope, I received a string of messages exactly like the first one that Wanago received after his firmware update problem. I've read this thread through several times, and some of the Linux commands started making sense to me. The first thing I did actually accomplished two things: It fixed the problem, and proved that my defective USB flash drive caused my scope trouble, not tinheads fixed (dso1kb_2.01.1_DSO1122S(140408.2).up) firmware. Okay, so I monitored the scope as it ran through the initialization loop to the pausing point, just before the auto restart. I then hit enter to enable the console. After that, I typed "killall dsod". That stopped the restarts. I then simply entered "/dso.exe". I think I was lucky, and the main program file was not corrupted/lost, because the scope came to life. I wasted no time and inserted a good flash drive with tinheads modified firmware and files (as above, dso1kb_2.01.1_DSO1122S(140408.2).up) which I had kept. I ran the updater right from the scope Utility menu as you would normally do a firmware upgrade. It ran (a bit longer, as tinhead said it would with the extra files on the flash drive), and then restarted. Voila! The scope started normally and has been working ever since. To tinhead: Thank you so very much for your dedicated interest in the Hantek/Tekway gear. It saved me tons of grief. I believe you should repost the dso1kb_2.01.1_DSO1122S(140408.2).up fixed firmware on your onedrive site for others to use. It ultimately worked for me, and I have the benefits of the new firmware version, as Wanago has described. I do wish Hantek would take that last copy of the bad firmware off of their onedrive site. It sits like a land mine for unsuspecting "S" series scope owners (I wonder how many there are of us?). Wanted to add: My DSO1122S has a hardware version of 1.02 dated 9-2012 |

you welcome! and of course good to hear that your handheld is back working. |
