| Voltcraft DSO-1084E stuck on boot screen |

| mateusz.kaczor:
Hello, At first I would like to say hi to everyone, I am completely new to this forum (although I have been watching Dave videos for years) I would like to ask for help in repairing the VOLTCRAFT DSO-1084E oscilloscope (Hantek DSO4084B). I bought it for a penny (already damaged) hoping that I would be able to do something with it. Unfortunately, I got stuck :( I checked other threads on the forum and I found nothing similar to this. Oscilosope is stuck on Logo/Boot screean or after "hard reset" in recovery screan with information "System is not shut down properly..."

Hi, I just would like to ask if you have any success to recover your scope? I am in the (almost) same shoe, my dso is Voltcraft DSO-1202D and after booting nothing work on it. I able to connect to it via UART and I see linux is running on it. Even mounts the pendrive (I am able to copy files from pendrive) I have run the recovery, no success. Also I have tried manually update the firmware without success. So currently I do not know what else can I do. Probably I full backup from another (working) device would be useful. regards |
