Bricked new GD-SC03 with new firmware #96
Comments

Having the same problem ... |
|
I'm at the stage now where it boots with root in r/w mode and that the hacks load from an SD. Can anyone zip up their /home folder? I assume that it contains all files necessary for proper operation, inlcuding wifi drivers. My /home folder containts very little files, no drivers subfolders and no kernel modules. |
|
I was excited to see this and try the tolder, but it's total size is around 8MB - while on my GD-SC03 the /home partition is mounted with only 5MB. I wasn't yet able to find the subset of files needed for a stable boot. I can get the device to boot and do a self test with a /home folder from a different image, but there again I'm missing files due to the smaller flash and the image comes from a different make. Ideally an image, tar ball etc from an GD-SC03 with the smaller flash like mine would help |

This is the result of this command: |

nykroy your blocks mtd are not suitable for Gymnae |

from the log Gymnae: |

I hope for a clean firmware.bin from the manufacturer to get the camera at least back into a working state. Right now it's booting then reboots after a minute, there's no reliable way to contact it on the network and now way to get an image output |
Dear @nykroy, I got myself a new flash chip with 16MB storage. Is your "guudgo_mtd.zip" from an GD-SC03 camera? I asked this already in the other thread, but could you make backups like this from your other GD-SC03s? I'd like to try and flash the mtd, packed as .bin files, onto the flash chip and then solder it onto the PCB. |

Yes i have two gd-sc03 tomorrow i will attached the two zip

Thank you very much, looking forward to it. I will report back and could share the binaries and process of using different flash chips to modify these cameras. |

Camera 1 updateversion=3.2.8.0121): dd if=/dev/mtd3 of=/media/mtd0.imgdd: can't open '/dev/mtd3': No such file or directory dd if=/dev/mtd0 of=/media/mtd0.img640+0 records in dd if=/dev/mtd1 of=/media/mtd1.img4864+0 records in dd if=/dev/mtd2 of=/media/mtd2.img27264+0 records in |

I am noob on linux. If hoy need something else tell me how can i help you |

Thank you, @nykroy for creating mtd images and sharing them. That is great. I created .bin files with a GK7102_Tools_ver.2.zip shared by @paus56 here: camera1.bin.zip Sadly, if I flash these with a modified CH341A programmer, I can get the flash to verify after using CH341A software version 1.1.1.32. But then when I solder the flash chip back, I get no output on UART and no IP. If I flash my 8MB backup or @paus56 supplied .bin for the IL-HIP291G-2M-AI, I can get it to boot, but then crash because my backup is faulty or because I don't have an IL-HIP291G-2M-AI |

:( I am Sorry to hear that. If I can help you the another way. Tell me how. |
|
You are plenty helpful, thank you :) Just to make really sure: You have also have a GD-SC03 camera from guudgo, correct? |

Yes I have two gd_sc03 from guudgo

Ваша камера сильно отличается от HIP291G сигналам ввода - вывода: камера HIP291G (из лога): в камерах разные сенсоры.... камера HIP291G (из лога): в прошивке HIP291G нет модуля сенсора: sc2235 поэтому возможно и перегружается ваша камера с прошивкой от HIP291G... вам надо искать прошивку версии: у вас что то осталось от родной прошивки ? |

Спасибо, что обратили внимание на различия в чипах SC2235 и HIP291G. Я сделал резервную копию своего флеш-чипа после прошивки этой прошивки: Это резервное копирование возвращает камеру в состояние перезагрузки, описанное в моем первоначальном сообщении Может быть, камера ожидает флеш-чип с четырьмя разделами (mtd0 - mtd3)? Помимо резервного копирования с IL-HIP291G-2M-AI, до сих пор я получал резервные копии только с тремя разделами. Переведено с помощью www.DeepL.com/Translator Thank you for pointing out the difference in the SC2235 and HIP291G chips. I did make a backup of my flash chip after flashing this firmware: This backup brings the camera back to the reboot state described in my initial post. Could it be that the camera expects the flash chip with four partitions (mtd0 - mtd3)? Besides the backup from your IL-HIP291G-2M-AI, the backups I received so far are with three partitions only. |

If you want i can add the home folder this friday when i return to home |
|
для этой камеры требуется файл сенсора: sc2235.bin поэтому не получается собрать блок mtd3 для прошивки этой камеры |
|
Damn it. I cannot find this sc2235.bin anywhere :( Thank you so much for spending time. Maybe a solution comes up - I will continue searching and annoy people :) Черт возьми. Я не могу найти этот sc2235.bin где бы то ни было :(( Большое спасибо, что уделили время. Может быть, появится решение - я продолжу искать и раздражать людей :) |

Great news! @paus56, this flasher readout also includes the much sought after sc2235.bin I flashed the bin onto a fresh 8MB flash chip, soldered it back onto the PCB and my camera is back from the dead and doing mighty fine with the read-only hack I also created a new repo to store my findings: |
can you share the software ? |
I tried to load the ONVIF firmware onto the system which is floating around. After that, the camera wouldn't boot no more. I have it at a state now where I can access it via uboot and telnet, for some seconds even have it available on LAN, but then it crashes.
My camera has a different Flash chip than most reported here: GD25Q64C, which has only 8 MiB instead of 16MiB, requiring a reduced /home folder - at least that is my current understanding.
I soldered myself an UART adapter out of an RS232 to USB adapter and here's the uboot log.
