I am contemplating upgrading my notebook’s MC7355 to MC7455. I am using it on the sprint network using the MC7355 sprint firmware. For the MC7455 on the Sierra Source firmware download archive I did not see a sprint-specific firmware. Even though one would think it is necessary to fully exploit the triband (LTE 25,26&41) capability of the device. But perhaps I am wrong and one of the generic firmwares is to be used for Sprint. Please let me know. Also please let me know if you have an opinion whether it is a worthwhile upgrade.
Hi,
Sprint FW is available at http://source.sierrawireless.com/resources/airprime/minicard/74xx/airprime-em_mc74xx-approved-fw-packages/
