problem updating Modem software 1.2.0 and firmware on Thingy91

[Marnix]

Hello,

1) I updated the modem software with connect programmer trhu a  USB connection on the Thingy:91

2) I updated al the HEX files in the "thingy91_fw_2020-04-29_bc7ade8b" on to the Thingy.

Q1) how can I see which files are on the Thingy91?

3) When I open LTE link monitor and select the Thingy.  It opens modem. see pic below

The modem is not working.

Q2) What did I do wrong?

Hi Marnix,
Since you update through (MCUboot) USB you need to select the "dfu" files.
So if you use one of the files in the folder /thingy91_fw_2020-04-29_bc7ade8b\images_dfu_hex/ you should be good.
e.g.
"thingy91_at_client_dfu_2020-04-29_bc7ade8b.hex"

Package contents:
images_full/          Full firmware images, updated over debug probe / development kit
images_dfu_hex/       Application images, updated over USB, HEX format
images_dfu_bin/       Application images, updated over USB, binary format

- Modem DFU completed successfully

- Write "thingy91_at_client_dfu_2020-04-19" but Programmer tells Does not need to be reloaded.

- Do I need to upload all HEX files in the folder to the Thingy one by one. (7 files)

- When test in LTE link monitor UART Modem UICC and LTE are all red.
