Upgrade Firmware EM7565 Failed

IoT Modules
1

Hi guys,

I got an EM9565-9 module for Lenovo laptop and would like to flash it to generic firmware to use on a WWAN box & a router. Unfortunately, I couldn’t flash the firmware. Can you guys help me out on this, please?

Here are things I’ve done:

  • The current firmware is 00.06.05.00 - GENERIC_001.007.000

  • I’ve tried to set up things on Ubuntu, flash the firmware to SWI9X50C_01.05.01.00_00_GENERIC_001.028_000, follow this guide on Github.

  • There was a successful message on the screen but it seems the new firmware never arrive.

  • I tried to flash again, three, four, five times - unfortunately, the result is the same

  • I ran AT!IMAGE=0, AT!RESET - then try to flash the firmware again, but no luck

  • I’ve tried to use AT!OPENLOCK command to unlock the module and flash it, but still the same

Here are several details from AT commands:

I’ve tried to set AT+CFUN=1 to get out of LPM, but it doesn’t work.

+CME ERROR: operation not supported

It seems this module is tied with Lenovo machine & its BIOS.

Can you guys please help me to make it work? Here is the firmware upgrade log: firmware-update-log - JustPaste.it

Does this help?

You meant use/replace antenna? I’ve tried a few but it doesn’t help to get rid of the issue. I still can’t set CFUN to 1.

i mean in your AT command, it says BIOS:1
