I know that apparently with this device you can't install from the webinterface but I want to give a try, I don't like to touch the hardware too much, however I have a USB to TTL that I brought few years ago (for school) however I'm not confident to use this alone
If I do it with my USB to TTL should I need a solder too ? (sorry if it's a dumb question)
Ummmm...since you have OEM firmware on it right now, you should be using the factory image.
Otherwise, you can explore web interface shell injection, as mentioned in TP-Link TD-W9980. As mentioned there, you need to split image sysupgrade into two, flashing the first part into mtdblock1 and the other one into mtdblock2.
Thank you I'm on it now, I really hope It will work this is my last chance however the Web Interface Hack tutorial mention the image for the TD-W8970 I don't know what to do
I'm doing the web interface shell injection right now with the "openwrt-18.06.1-lantiq-xrx200-tplink_tdw8980-squashfs-sysupgrade.bin" image
I should format my USB key to msDOS/vFAT, and I'm using KDE Partition Manager , I found msDOS but didn't found what vFAT, I formated my USB key to FAT32 is this ok ?
Or I have an idea I use the "openwrt-15.05.1-lantiq-xrx200-TDW8970-sysupgrade.image" image like used in the tutorial and I upgrade to "openwrt-18.06.1-lantiq-xrx200-tplink_tdw8980-squashfs-sysupgrade.bin" in the web interface of openwrt is this possible or not ?
I know what I did wrong, when I written to /dev/mtdblock1 the first time It said " no such space left on device" , so with the stress I didn't read that this was intended behavior and through I made mistake so I removed the USB and made the original firmware, and after few minutes I read in the tutorial this was intended behavior so I made again my original firmware and did telnet again however I fucked up because I write .image instead of .sysupgrade
So i guess firt mtdblock1 is written correctly but not mtdblock2
I have the same router with OpenWrt v18.06.1. At this point you need a USB-To-TTL adapter rated 3V and then you will need to solder three wires on the board, TX, RX, GND (should not be much of the problem though). If you dont have any soldering skills watch some youtube videos to learn.
Once you get serial access, you can stop the boot while loading U-Boot and then flash OpenWrt through TFTP. In my experience, using a serial connection is much less painful than any other because in the end you may need it anyway, so why not just have it already.
