its solved, everything is ok now.
instead of using the profile tplink_tl-wr703n, I created a new one, that caused the problem.
update 1:
I can confirm that 19.07.4 and 19.07.6 worked well, the following happened on 19.07.7
thank you for your guide. I followed it until the end. however, I am currently stuck in failsafe mode for some unknown reason like WebInMe, the blue led is blinking fast.
I used the 'run firmware_upg' from the uboot. then immediately it boots up in that failsafe mode that I do not know how to exit. the 'mount_root' command also failed.
the ram and flash chip seemed to be fine, the ram passed mtest, and the old 17.01.7 worked fine on this hardware also.
the following is the serial boot log, any help is appreciated.
