UC15E firmware Recover

I accidentally pulled the USB cable when updating the UC15E firmware, after that I didn’t see the DM port. Is there any way to fix it ? Does UC15 have a USB boot pin? Thanks

Dear Iasutsatu,
Thanks for your inquiry in Quectel forum.
About your issue, please use UART port to upgrade the firmware to have a try. Thanks!

Is it possible to send me the firmware update of the UC15EQAR03A10E1G model please. I have already sent an email at support@quectel.com but i am still waiting.
Thank you.
