A few days ago I got an TD-W8970B and flashed it succesfully with OpenWrt 18.06.1 .
I was a little bit struggling with the Wiki Page of the router.
One hand there is a huge amount of information.
Other hand it seems some of the information is outdated and spread of to the 3 router types 8970/8980/9980.
Because I am new to this router and also not an OpenWrt pro (only a user for some years on 1043nd) I don't want to change the info in the Wiki (or at least not without confirmation)
What I have noticed:
The "danger field" with the information not to upgrade to 12.10.2013 or newer of the TP-Link firmware:
Even if you get a router with such an antiquated FW version, there exists no factory image for this router to flash via the webinterface.
I would delete this info.
I have counted the Gbit ports again and again, I found only 4.
Only if you count also the CPU port it has 5. I don't think this is correct at this point.
Also the info about the modem is confusing:
ADSL2+ is correct with stock FW, but with OpenWrt it is VDSL. Only I am not sure how to show this on device page ...
Installation without opening the case (Web Interface Hack)
SSID Config Injection
I don't know what is meant by "newer firmwares".
In my case I tested version 141008,150526 and 160808 for W8970B without success.
Maybe someone could tell with which FW version this procedure is working on W8970(B) .
Or maybe this works only with W8980/W9980?
Opposed to the info in the wiki, with this procedure I was able to get a root shell on my W8970B with FW version 160808.
Installation via telnet/root shell:
I think it is mandatory to use OpenWrt 15.05 for flashing via telnet. After this you can upgrade to 17.01/18.06.
Something seems to have changed in partition layout of 17.01/18.06, and if you use these versions for first OpenWrt flash (via telnet, not serial) your router will brick and you need to use a serial connection to debrick.
Maybe I am wrong, because there is the sentence: "Rumours are that with the recent OpenWrt that you need to take care that the image you write to mtd2 needs to be extended with 0xff characters to the end of the partition"
Only, I don't wanted to test this because of "rumours", I don't wanted to have a bricked router afterwards...
Also I would like to copy the whole "telnet procedure" to wiki of W8970. At the moment it is described only on wiki for 9980 and in the old forum.
it is described the ethernet ports would act like a hub.
To me that seems to be wrong with 18.06.
information about "VDSL.BIN" and "DSL Settings" is only for 15.05 and has changed in 17.01/18.06 .
Not sure if there should be any information about xDSL FW and configuration at this page,
because FW file and settings are the same for at least all Lantiq based devices.
Only, I found no page about FW files in the Wiki (actual info only in the forum?)
Ok, now I have produced a forum post that is at least as confusing as the wiki pages for this router...
Maybe someone could confirm and/or add information (e.g. about stock FW used for Installation without opening the case) and I would change the Wiki page.
