Hi all, hi lpm11
"Firstly - DO NOT upgrade to the 28.08.2013 (or newer) firmware on TP-Link website. It has modified u-boot, and applies a NEW UNKNOWN header - first byte is 0x03. We don't know how is it working. " - this is the problem. TP-Link introduced a new format of image files. It is diffrent than in other TP-Link firmwares, so that is the reason we can't do the correct image file, upgradable by http.
Is my understanding right, that it is basically possible to install OpenWrt via the web interface, as long the firmware is not upgraded to the version of 28.8.2013 or newer ? (mine is 0.6.0 2.1 v000c.0 Build 130415 Rel.34164n).
I tried to install the available openwrt images via the stock web interface with no success. (openwrt-lantiq-xrx200-TDW8970-sysupgrade.image, openwrt-lantiq-xrx200-TDW8970-sysupgrade_v39435.image and openwrt-lantiq-xrx200-TDW8970-sysupgrade_v39586_EXPERIMENTAL_usb3.image). With all of them I get the following error:
Error code: 4503
The uploaded file was not accepted by the device.
Am I missing something here or is serial access (soldering) and deploying the image via tftboot also necessary with the old firmware version?
If there are no compatible (http-installable) images available on the web, can anyone give me some short hints on how to build one on my own?
