Note:               Applications built with a version before Open AT Application Framework 2.52 have to be rebuilt with this Open AT Application Framework.

On AirPrime SL808xT with Firmware 7.50.0.A1, firmware (SIERRA_OAT_FW_752_5_A5_2_FULL_sl808x) should be upgraded before bootloader (SIERRA_BOOT_S4.1.0.24_sl808x), if .cwe or .dwl files are used for upgrade. R7.52.5.A5.SL808x_201611030614_2.exe can be used to recover AirPrime SL808xT in bad state.

For the upgrade procedure, you can refer to:

·         The upgrade procedure through X-modem
