MC7455 modem won't connect low power mode

Post by gurutedd » Wed Jan 29, 2020 2:07 pm

When I run a at!gstatus? I get low power mode and no signal read outs. I have searched and searched around. I first tried to flash the firm where with a windows pc with a usb adapter. I then installed Ubuntu and flashed it with a linux files. Still the same issues. No dice.

If it is a MC7455 (as opposed to an EM7455) you might try doing an reset to OEM.

I tried to do a reset and it said there are now saves nor did it change anything. I did both at!RMARESET=1 and at!RMARESET=3 neither worked.

current carrier name: mismatched
current config name: mismatched

Says this to when you do a IMPREF command.

I would reflash the modem with generic firmware, and then reflash a second time. This will generally get rid of the carrier mismatch error.

Here is an update on my issues. I have flashed this modem with a linux and windows machine and I am still getting low power mode. I have gotten it out on a windows pc with a at+cfun=0 command. I can't ever get it online with a WE826 from LTEFIX.com. I have tried everything I can on this.

You got me. Where did you get your modem?
