The router reboots and is locked again.
If you have stumbled upon the filename while compiling OpenWrt, flashing a 4G LTE router, or digging through cellular baseband logs, you are dealing with a critical system configuration package. This archive file contains the underlying hardware parameters and radio frequency calibration configurations necessary for cellular modems powered by the Marvell ARMADA Mobile PXA1826 (later acquired and maintained as the ASR1826 ) cellular chipset. pxa1826-cfg.tar.gz
To manually read or tweak carrier aggregation logic inside the configuration package on a Linux system, use the terminal:
Because these modems act as independent embedded Linux computers inside your router, their behavior is directed by specific system configuration files. Anatomy of pxa1826-cfg.tar.gz : Shell scripts (like
: After a reboot, you will need to re-enter 123456 in the MEP settings screen again. You do not need to re-upload the TAR file each time—just enter the unlock code.
Powering devices from tier-one OEMs like Samsung. Outdoor Units (ODU): Such as the MU261 CAT6 ODU. You do not need to re-upload the TAR
The .tar.gz extension denotes a . When dealing with telecommunication modems built on the PXA1826 platform, expanding this package typically reveals a strict nested folder directory required by the router's flashing utility.
