Hi guys, I am writing through an interpreter, please help to restore the native firmware of TP-Link. do everything according to instructions but he always goes to reboot, if not difficult to lay out detailed instructions

Rebooting in 1 seconds..

Hi gupetulya,
would you mind to explain why you want to go back?
it is easy and you could figure it out by yourself, maybe you did already.
Bytes transferred = 7995392 (7a0000 hex) TP-Link Image
Bytes transferred = 6815748 (680004 hex) OpenWRT-BB Image
I wonder why your erase command is correct but the write is not.
"sf write 0x80800000 0x20000 0x680004" should be "sf write 0x80800000 0x20000 0x7a0000"
so some bits are missing at the end ;-)
did you had rebooting issues with OpenWRT? it is not totally clear from your first post, maybe you can send the console output for your OpenWRT flashed device too, you can switch between the versions as you like.

the fact is that I am almost 2 days sitting and could not understand what I'm doing wrong ... but you're a genius, all done without any problem, for it thank you, and why did you decide to flash back, I like to experiment)))

router works but Wi fi does not work, I'm doing wrong?

Maybe nothing, but maybe you did already. First question is, did you erase the radio partition by accident?
it holds necessary data for the wifi chips, this is atheros related. you might have an backup of your chip stored somewhere.
0x0000007f0000-0x000000800000 : "radio"
without this there is no wifi unless you put valid data back into the radio partition.

mine is looking like this, hope it is ok to post it that way, the MAC is stored in there too masked mine with XX XX XX XX XX XX

I did not specifically erased, this router has given me my friend request on his openvrt not right here, and I had to restore .. I'm not good at these things so much. so if you can help me how to get it back in full operation

Hi gupetulya,
would you mind to explain why you want to go back?
it is easy and you could figure it out by yourself, maybe you did already.
Bytes transferred = 7995392 (7a0000 hex) TP-Link Image
Bytes transferred = 6815748 (680004 hex) OpenWRT-BB Image
I wonder why your erase command is correct but the write is not.
"sf write 0x80800000 0x20000 0x680004" should be "sf write 0x80800000 0x20000 0x7a0000"
so some bits are missing at the end ;-)
did you had rebooting issues with OpenWRT? it is not totally clear from your first post, maybe you can send the console output for your OpenWRT flashed device too, you can switch between the versions as you like.

that incorrect write command is here http://www.pierovdfn.it/2014/08/09/tp-l … 0-openwrt/ which is very high in google searches for openwrt w8970

I'm a little lost with my new TD-W8970B. I connected a serial console and I'm able to tftpboot images.

My problem now is, that I can't find the image 'openwrt-lantiq-xrx200-TDW8970-uImage-initramfs' for the method described in the openwrt wiki. I can't find an image with initramfs/ramdisk support at all :-(

I tried  W8970.img and luci-lantiq-xrx200-TDW8970-sysupgrade.image from here http://tplink-forum.pl/porady-serwisowe/w8970-openwrt/

.. but they also seem to be just sysupgrade images and without initramfs support, because both end up after bootm with:
[...]
[    1.972000] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Do people exist on this planet, that had success in finding an initramfs-image  and using the method from the wiki??
http://wiki.openwrt.org/toh/tp-link/td-w8970

Thanks

Firmware Version:0.6.0 2.5 v000d.0 Build 140320 Rel.67818n

I've never found or used the "initramfs-image". I was using the boot loader for flashing, described with
the rylos image (load image to ram, erase flash, copy image to flash).

Ok, thank you, then it obviously does not exist in public. I will try to build/compile  an "initramfs-image" for 14.07 by myself (allthough I never tried that before).  If it fails, then I'll try the procedure with the "rylos-image". I had read about it, but it seemed to be a little dated (2013?), so I wasn't aware, that rylos is still the only available image for the first flash.

you can flash the openwrt-lantiq-xrx200-TDW8970-sysupgrade.image standard image via ftp

#setenv ipaddr 192.168.1.1    #IP of Router
#setenv serverip 192.168.1.254    #IP of tftp Server
#tftpboot 0x80800000 openwrt-lantiq-xrx200-TDW8970-sysupgrade.image
#sf erase 0x20000 0x7a0000    #size of image is 680004 but erase 7a0000
#sf write 0x80800000 0x20000 0x680004    #write image to flash

you can flash the sysupgrade image directly to your router no need for rylos-image for me.

Thank you very much, Wingman2k, for me it comes a little too late, because I build an image with initramfs today and was able to follow the wiki-method. But to other users your howto will be a big simplification and a great help!

Personally  I'm now at the point of searching the firmware-blob vdsl.bin for Annex B. I found a script on my new openwrt-router (BB14.07) named /sbin/vdsl_fw_install.sh, which seems to be a good starting point:

#!/bin/sh
. /lib/functions.sh

Seems that your "vdsl_fw_install.sh" script is not up to date, the current one is downloading and installing "Firmware_Speedport_W921V_1.21.000.bin" (which is downloadable at the referenced URL). The modem firmware is the same in both versions (same md5sum).

  http://hilfe.telekom.de/dlp/eki/downloa … 21.000.bin

MD5 (vr9_dsl_fw_annex_b.bin) = 59dd9dc81195c6854433c691b163f757

It's also possible to extract the dsl firmware with your PC and put it manually to the router.

If you are interested, you can join the IRC channel #openwrt-td-w8970 at freenode. It's a try to establish this channel (dedicated to TD-W8970).

Thank you, asc, you pushed me in the right direction. I had success with the excellent work of member s7a7ic here in the thread:
https://forum.openwrt.org/viewtopic.php … 64#p261864

In short: I fetched Firmware_Speedport_W921V_1.21.000.bin from the telekom site and copied it with scp on my router under the fake name /tmp/Firmware_Speedport_W921V_1.20.000.bin, so that the tool /sbin/w921v_fw_cutter on the router can find it (the 1.20-filename is hardcoded in that tool in BB 14.07).

It cuts the vdsl-firmware:

 root@OpenWrt:/tmp# w921v_fw_cutter
Arcadyan Firmware cutter v0.1

I checked the checksum and copied it in place:

For annex b I edited the default /etc/config/network to:

config vdsl 'dsl'
        option annex 'b'
        option firmware '/lib/firmware/vdsl.bin'
        option tone 'bv'
        option xfer_mode 'atm'

I can't test an ADSL connection before monday, but everything looks ok at the moment, the pppd is waiting for responding PADO packets:

logread
[...]
Wed Oct  1 14:21:39 2014 daemon.warn pppd[2300]: Timeout waiting for PADO packets

Wed Oct  1 14:21:39 2014 daemon.info pppd[2300]: Exit.

By the way, I found a newer firmware 1.22 at telekom (Firmware_Speedport_W921V_1.22.000.bin) and the contained blob has the same checksum as in 1.20 and 1.21:
59dd9dc81195c6854433c691b163f757  vr9_dsl_fw_annex_b.bin

Great forum, thanks to all!

Hey Hank,
you are one of the few Annex B users here, it would be nice to hear if you are successful.

Hi Hank, good news so far, depending on your Country or ISP you have either atm or ptm if you have ptm (Germany-Telekom) you need to install kmod-ltq-ptm-vr9 and set "option xfer_mode 'ptm'. Maybe also VLAN settings for the pppoe connection later on (Telekom-VDSL), try to check it before to prevent headache.
Good Luck

It works. I had the W8970B on an annex b line today (plain ADSL based on ATM from a german city carrier).

A summary of my first settings:

/etc/config/network:

        option vci '32'                   
        option encaps 'llc'               
        option payload 'bridged'

        option ipv6 '1'                   
        option macaddr 'e8:de:27:2e:XX:XX'
        option username 'XXXXXX'      
        option password 'XXXXXX'

        option annex 'b'                  
        option firmware '/lib/firmware/vdsl.bin'
        option tone 'bv'                        
        option xfer_mode 'atm'

The LuCI GUI shows:

Firmware Version    OpenWrt Barrier Breaker 14.07 / LuCI Trunk (0.12+svn-r10530)

The sync-LED is on and status-page shows:

Although it seems to be synced with 4096 kbps, a first download-test gave me just 1280 kbps, so eventually there is space for some tweaking.

cheers

On a high-quality ADSL2+ line I get full speed, so everything is OK with the modem:

Hello there, so far still No One has managed to tweak the SNR margin? All my attempts has failed so far and i dont find any good documentation about that. Same about tweaking interleaving delay. There must be a way to do it, maybe through the Modem CLI shell but the documentation is poor about that.

Not a secret, for a "correct" use take a look to  lantiq_dsl.sh   and get the idea.

For a complete list ssh to your router and type

  /sbin/vdsl_cpe_control --help 

and

  # /sbin/vdsl_cpe_control --console 


(it opens a cli for parameter management, type help)

 DSL_CPE#>help

i try long time ago several ways to change snr, i belive is something like

 DSL_CPE#> locs 0 -20
 DSL_CPE#>acs 2
 DSL_CPE#>quit 

and take a look

  /etc/init.d/dsl_control lucistat 

hi joseba_g

I have a router with firmware openwrt w8971 but I can not change the value snr
I ask you, please, if you can make a more detailed guide, thanks for your help.
