that's at least progress, this was a stripped tplink image ?
Which firmware version is this? Sometimes, old firmware versions do not boot on all hardware versions. Judging from the filename, it's 1.1.1 while 1.3.0 is already available.
nicefile, he saved me
as a result, I completely flashed the device, its image, through 2 menu items and everything worked, at least for now)
so I've removed header + uboot of total 0x20200 like andyboeh suggested.
Now when we know so much about recovery @ParinovYT can proceed with OpenWrt support
well, if we have sorted out the restoration of my router from the brick state, I think I can flash the router calmly with your test firmware, for me anyway the issue with the working initramfs-kernel for revision v1 remains open, since I am not able to assemble such a device for our device.
