Hi, I have a problem with a few Night Hawk M5s. Non of them are connecting to an LTE network. I've tried differed Sim cards and carriers . After reading the forum, I think this might be a firmware issue. Can someone help me downgrade the firmware, to try and get it working.Current firmware: NTGX55_12.04.12.00. Hope to hear something soon!

This is 100% a firmware issue, either modem wise or device wise. My m5 was working with the 3 big networks in the US, ATT verizon and t-mobile until it updated and now it's doing nothing but showing 000-00 and mobile network disconnected. It also shows 100EUS on it though it's a 100NAS model. The lack of providing any easy way to update this brick is testing my patience.

I agree. The fact I'm experiencing this problem on multiple Night hawk M5, says enough. The interface lets me pick my own firmware to update. But there is no firmware to be found online..

Hi Blanca_O I have sent you the information requested. Can you help in finding a solution?

Could you please provide a model.json file and send it to me by private message? - Logon to the webui (http://192.168.1.1 ) as an administrator- Navigate to URL http://192.168.1.1/model.json via the same browser window- Capture the results (by selecting all + copy) and send it back Would like to check how you upgraded your device. Thanks John

have you checked if APN settings done correctly for the SIM card you are trying?

  Yes, I've uses the sim cards in other devices and used the same APN.
  I have this problem on 3 Night hawk m5s. None of these devices can find any network in a manual search. First I thought the antenna might be broken but this would be strange if it happens to all 3 at the same time. After some digging on the internet, I found this might be a firmware issue. So I would like to upgrade or downgrade manually to try and fix the problem. Do you know how to go about this. I cant find any firmware online.

Hi Flappie23

Please provide the device SKU (e.g. MR5200-100EUS).

Who is your Internet provider?

Kindly send me a private message with your name, email address and serial number of the non-working M5's.

Regards,
Blanca

Just set it up and everything looks fine, but it won’t connect to the network. Tried rebooting, reseating the SIM, and even a factory reset—still no luck. Super frustrating, especially for a device at this price point. It’s like preparing a great dish and missing the key flavor. Any tips or fixes would be seriously appreciated!
