Firmware Request RM551E-GL Q1-C3877

Hi there,

I have a router with this modem (it also says “Engineering Sample”):

Model: Quectel RM551E-GL
Firmware: RM551EGL00AAR01A01M8G
Full revision: RM551EGL00AAR01A01M8G_01.001.01.001

Is there a newer firmware available? I want to improve the 5G speeds in Germany.

Thank you!

I have sent to your email, please check.

I recently received the unit but haven’t turned it on because I have a problem; I need a cable for the internet port.I recently received the unit but haven’t turned it on because I have a problem; I need a cable for the antenna port. Can you tell me what type of antenna port the unit has so I can find the appropriate cable for it?

Additionally, please share the update file with me. I purchased the unit from a seller in China through AliExpress, and I expect it to be on the first update available when it was first released to the market.

Hello, thank you, but I was late, which led me to search the Internet, and I found a modified version that I installed because I had a problem with the stability of the 5G connection speed and also getting the real speed that I get from my service provider’s tower, as my Huawei phone and router are twice as fast as the speed that I get from the modem, which caused me inconvenience trying to search for any quick solution. I want to use my combined router as quickly as possible and enjoy the speed of the Internet. Please send the latest update for the R02 category. I spoke with the artificial intelligence about installing the version that you sent to me via mail, and he advised me not to do that because there is a danger to the modem that might cause it to malfunction permanently. He advised me to request a stable update suitable for the version that I installed. I am currently interested in the stability of the Internet in 5G. The type of connection supported in my country at the present time is NSA 3 or 4 4G frequencies with two 5G frequencies, whether different or the same frequency.

If upgrade from R01 to R02, it will have some risk, like unexpected behavior.
