Hi All,
Someone has experience for enabling uplink CA for Qualcomm devices?
I edited some related files but still not enabled.
Does it has any hardware requirements other than chipset?
Tested chipset is X53 and for Xiaomi phones is enabled by default, but Samsung no.
Your device must support UL-CA combination to use it. You can check these on website: https://cacombos.com/ . Most of Samsung devices do not support inter-band UL CA.
If there is no UL-CA combination defined to modem firmware there is not much you can do. Modem firmwares you can’t edit without break signature and then your modem will not work anymore because it require signed modem firmware.
