[SM-F926B] ERROR: Failed to send handshake! #504
Comments

Are you on Ubuntu? It fails on the first handshake package, so it is unlikely that it is due to protocol changes (unless Samsung has re-done the protocol from scratch for this device). Seems more likely that the connection needs to be reset before handshake, as in this PR. You can download heimdall with this (and other) fixes here: ubuntu 20.04, archlinux and alpine linux. Could also be a permission issue, try running heimdall as root, or make sure udev rules are installed |

Hi, I am using fedora 35 on a aarch64 SoC. But I was able to use Heimdall with a SGS8 with no problem previously. The issue also happen as root and I do have the udev rules set and triggered properly. |

Apparently odin 3.14.4 works for flashing this device, so seems unlikely that protocol has been fundamentally changed. However, looking at the PIT is seems that it uses a 6th version of the Odin protocol (first time I see that, I only have devices using 4 or older): (printed with heimdall from this branch) so maybe something is different, but then again: seems unlikely they would change something as fundamental as the handshake. Would be interesting to see usb traffic logs (captured with for example wireshark) of when stock android is flashed onto the device with odin. Such logs would be the only way to see if the transfer protocol is different. |

You can also try increasing the timeout (third arg to SendBulkTransfer) of the handshake package, and probably the response, to something higher like 6000. Really seems more likely that issue is that libusb_reset is needed, or some issue with libusb on feodora/arm64, or just that the usb cable is bad, rather than that heimdall does something wrong (since heimdall doesn't even do anything, first packet fails) |
omg thank you i was having the same issue this took me so long to find |
It is not version of some sort. Odin, nor Thor (it's successor) use data after entries count, |

Solved using the PR mentioned in the previous comment |

I am in the same situation. Linux Mint 21 (aka Ubuntu 22 LTS) and the heimdall in the standard repo (1.4.1) does not work. With the 2.0.0 of the link below , it works. I guess I should report this to Mint folks ( or Ubuntu 22). |
No, it is an unofficial fork. Maybe there is a chance they will use it, but who knows. |

Duplicate of #413? I just added some help there. |

On Manjaro, I managed to get it to work by uninstalling |

In my case, I noticed that when in download mode, you can only flash once. If there is a pending operation, it will remain pending until you restart the device. The The easiest way I found to deal with this while desperately trying to root the phone as soon as possible is by doing the following:
