MR6500 openlock error

Sorry for being a newb - I'm trying to use the AT!OPENLOCK command on my MR6500, but I keep getting "error" in response. AT!OPENMEP works fine. I'm on Firmware NTGX65_10.0.31.01. Example - Challenge BFA9DF196842AA04, Response E6419E4284E3CEA1. Am I doing something wrong?

If anyone is wondering, I finally figured it out by using device SDX55 to generate the code with sierrakeygen.

Hi suprguy,

I have a MR6500 that I got in US, locked to AT&T bands, which I would like to unlock, as I´m now in Dubai, and cannot use it with 5G, may you please share how did you succeed on unlocking it ?
