It would also be beneficial if you could provide the delta file.

Here is their advice;

"For the customer I would recommend to run something along the line of
`dfu_target_init(MCUBOOT_IMG_TYPE)`
`dfu_target_close(false)`

Before the device connects to the network or shutdown the link and do those commands so that he can ensure that device is not busy with a network link before starting trying to delete as this is identified as the causes this error condition. It's a bit weird that it doesn't time out, but I think this keep checking the modem for replies and if it doesn't receive it. It will time out. The customer could also add their own hard time out to dfu_target_modem. This would allow them to have an escape hatch."

Ok, I will report this to the modem team to see if they know something about this.

No this does not happen when I upload a newer version.

Why I would be updating the same version is because I had an early release version and tried to push the official release version. This version had the same version number and bugged out I would like to not have this issue if a similar situation occurs in the future.

The second reason that I'm searching for solutions for problems like this is to cover all bases in regards to stability issues especially in regards to end-users, accidents, server faults and to make sure it won't happen if the problem is forgotten about when time passes.

Hello,

[quote user=""]The first problem that when I try to push the modem firmware to the device with a version match (device version 1.2.2, update version 1.2.2) the chip rejects the update but the modem will get stuck in the following state after a DFU socket has been created and the firmware version has been checked.[/quote]

Does the problem happen also when you update to a newer version of the modem firmware? I know that it isn't possible to update to a previous version, not sure about updating to the same version (and I have no idea why you would want to do that anyway).
