There are two identical HUAWEI B880 4G routers locked under Beeline. One has already been flashed with the left firmware, it must be returned back to Beeline. It was not possible to find the proprietary Beeline firmware, but it was possible to solder to the UART and watch the download log, and if you press Ctrl-C in time, even enter commands. There is an experience of uploading firmware via tftp, but there was no need to do the opposite. I want to merge the firmware from my native Beeline router, but I don’t know how?

You can merge via JTAG, then try to "sew" the firmware from the dump, if you are interested - write!
