This firmware im using is not stable and keep falling back to lte speed when using 5g nsa and keep disconnecting. Using suncomm 08 ultra.
Sorry, I don’t have beta firmware.
What’s the difference between the two ?
Dear @cevadaroses
Currently, RM551EGL00AAR01A04M8G_A0.001.A0.001 is the latest one.
Dear @Hariz_Aqim
We have an official firmware, but it is old than yours.
Ok . So the R02 is still the latest most stable one ?. I have a problem with it. On 5g nsa , it keeps falling back to lte speed and like it only prefer lte even though it shows im connected to 5g nsa
Dear @Hariz_Aqim
Your current firmware is beta, it didn’t test internally and only resolve single issue, so I don’t know how you get it.
It is not recommended to test with beta.
i got this firmware when i bought suncomm 08 ultra. Then can u please send me the official R02 version ?. With instructions how to flash it please. Email : aqimhariz707@gmail.com .
I installed the version you sent. which is RM551EGL00AAR01A04M8G_A0.001.A0.001.
After this my suncom router is not stable at all. I have T-Mobile SIM.
5G-SA starts with 4CA but after some time it’s going back to single network and no internet. I checked it with rebooting resetting the router it didn’t work. Then I changed the network mode to 5G-NSA. After that router says I am logged in to LTE. The condition is same no internet. Then I flashed it back to my old firmware RM551EGL00AAR01A02M8G_2024_12_23 has no issues.
Any advice?
HI Please send me the latest firmware file thank you!
Dear @ruvan
It seems there is some compatibility issues with your SIM card.
You can select a stable firmware for working.
RM551EGL00AAR01A02M8G_2024_12_23 is not our firmware version, I am not sure whether it modify our firmware.
