Hi Team Teltonika,
my TRB501 currently uses modem firmware RG520NEBDCR03A01M4G. Quectel informed me that the most recent version is RG520NEBDCR03A05M4G.
Can you please provide me with a package to upload through your web interface? Or is there a way to flash Quectel’s update package somehow?
Thank you!
Greetings,
Could you please clarify why you’d like to update the modem’s firmware? Are you currently experiencing any issues?
Best Regards,
Justinas
Hi Justinas,
thanks for getting back to me. According to Quectel’s release note file V0305_A0.300.A0.300, which I am unfortunately not allowed to upload here, A01M4G is a pre-mass production firmware release for engineering samples.
I do appreciate that Teltonika is getting a brand new modem like the RG520N to market quickly, and the whole TRB501 package has the perfect combination of specs for me. That said, I do expect updates to mass production firmware releases after some time.
In addition, the changelog from A01M4G to A05M4G is massive and includes many useful features. A05M4G is the first firmware version that supports Regulation (EU) 2022/30, and will therefore be mandatory to operate this equipment in the EU.
Again, if you cannot provide a firmware file yet, I am happy to flash the Quectel package myself through the CLI with the right instructions.
Thanks and kind regards
Florian
Greetings,
A modem firmware upgrade is typically performed only when it is mandatory specifically, when we know that updating the firmware will resolve a confirmed issue.
In most cases firmware upgrades are carried out only after the underlying problem has been identified. The commands required for this process are not publicly available, as incorrect use could damage the device.
If you believe a firmware upgrade is required for certain features, please let us know which features you are referring to.

I believe I did make myself clear why I consider an upgrade to be mandatory in my previous post.
If you believe that shipping pre-production firmware which does not support 2022/30 is acceptable, fine. I’ll go ahead and figure the flashing procedure out myself. If it works, I’ll keep the device. If not, I’ll return it anyway, either working or broken.

Did you figure out how to flash?
I currently have the same issue with this politics…
@NojuHD I had ChatGPT come up with a step-by-step guide, and it makes sense. Essentially running QFirehose - you can obtain the latest version from Quectel - after putting the modem into USB mode. The latter seems to be the greatest risk, as the way Teltonika configured the modem this wasn’t meant to happen. I haven’t decided yet whether to spend some hours of my life devoting to that, yet the upcoming days might provide an opportunity. 
The other option would be to simply send this thing back to Teltonika, which has become even more attractive since I found out the 2nd batch will feature eSIM functionality with no way to enable this on a 1st batch device.
Hello,
Apologies for the delayed response.

Thanks Marija, form is on its way.

Hi @Marija,
thanks for reaching out via e-mail and offering a remote session. Unfortunately, while I have local access to the device, it is my single point of connection to the internet so this might be hard to do. Would access via RMS help? If not, I am confident I’d be able to follow instructions even if the process is not straightforward - I’ll figure it out.
