I have some LS300 with fw 4.3.2.006 and i would like to upgrade to latest version but I am not able to find the 4.3.5 or any other old versions.
please help me to find there location.

Thanks

Which carrier are you using the LS300 on?

I also require the older version of LS300 firmware for ATT, Verizon, and Sprint gateways but have not seen a download location for anything but the most recent.

For devices running ALEOS 4.3.3 or earlier, install ALEOS_4.3.4_LS300_ATT_UpdatePack before ALEOS 4.4.4.004:

For devices running ALEOS 4.3.3 or earlier, install ALEOS_4.3.4_LS300_Verizon_UpdatePack before 4.4.4.004:

I need the location for the ALEOS 4.4.3 for LS 300 provider AT&T

I’m looking for LS300 Sprint Firmware 4.4.0 because I am running 4.3.5 and need to step to 4.4.0 before going further. Anyone know where to find this on the Sierra Wireless website?
