Does anyone possible know the AT commands and pid/vid to convert the dell 7355 to oem? Please and thank you. Also I don't see the com port in windows and tried it in a R00ter build since that method was in the instructions for the 7455 linked on this page but even though it says modem present the send command is greyed out. If i try to paste a command like AT!ENTERCND="A710" it instantly disappears.

I did and finally got to where i can send at commands via R00ter thanks to that link and multiple tries but it won't let me run the reset to oem command and the pid/vid and i am guessing the rest of the commands are different for the mc7355 i have found different ones just don't know which to use. I tried AT!UDVID=1199 and AT!UDPID=9041 and it seems to have worked . thank you for the response . Jim I have tried to reach you via sale support on the lte fix site and pm here about purchasing equipment but I have not heard back and it's been a few days since the first on lte fix.

Responded to your PM.

To reset the MC7355 (MC7354) to OEM status:

Code: Select all

AT!ENTERCND="A710"
AT!RMARESET=OEM
Note that by resetting to OEM, a vendor branded modem that has been modified, will resort back to the vendor settings.
