I was pretty sure I have had bricked my router. But it was interesting for me that leds were blinking differently when I powered on the router with reset button pressed. I thought that maybe router is alive waiting for firmware. Then I have found this article: https://www.trishtech.com/2015/06/unbrick-tplink-wr740n-wifi-router/
... and following it I was able to unbrick my router TFTPed original latest stock TP-Link firmware downloaded from https://www.tp-link.com/us/download/TL-WR1043ND_V1.html#Firmware renamed to wr1043nv1_tp_recovery.bin
Afterwords I have flashed latest DD-WRT r35034 released on 17.02.2018 (DD.MM.YYYY Smile)

Great to hear! Just noticed this is also described in the OpenWRT wiki. Maybe I should have tried that first, but I got a v1.2 and they say it starts working around v1.8. Is it possible to upgrade the bootloader to make further debricks easier?

https://openwrt.org/toh/tp-link/tl-wr1043nd#firmware_flashing


After wasting some time because of a bad solder joint, I was also able to debrick it with the serial port of a Raspberry Pi. Directly flashing LEDE…factory.bin succeeded. This video explained it really well:

https://www.youtube.com/watch?v=IHNrnLnLakE


I got way better wifi transfer speeds than before (15 to 35 MBit/s which is about equal to earlier versions of dd-wrt).
The setup of LEDE including printserver was also easy without the need of ssh. I really like the interface and would definitely recommend it to everyone who has trouble with dd-wrt on the 1043nd v1.

But I am still not sure whether
Code:
mtd -r write LEDE-factory.bin linux

would have worked directly. Probably not.


Is the webupgrade working again with a clean install of r35034? And also with an upgrade as described in this thread?

Today I tried to flash newest DD-WRT r35244 released yesterday and... it's not possible! Flashing process is ended in one second by reboot but new version is not there.
In other words: DD-WRT used to be the best firmware but since Mr. BrainSlayer modification is useless at least on TP-Link WR1043ND v1.9.

No, it doesn't. I tried to upgrade latest r35244 over r35034 but it's not possible. Conclusion: useless firmware for TP-Link WR1043ND v1.x.

check the size it may be too big many routers cant fetch it due to size issues..

can someone please tell me how to determine TP-Link C7 V2.0 bootloader size?

Is it the same as 1043ND?

That's the case this time... it is wrong firmware header (DD-WRT instead of TP-Link being looked for... or other way round).

You're right, I replace the firmware header "TP-LINK Technologies" to "DD-WRT 24".

After making the changes I run CRC32WRT.exe on the modified image to generate a new CRC32 that will overwrite on the image at offset 0x8. If this step is skipped, the image will not be accepted by DD-WRT due to mismatch between the content and the CRC value. To get the new CRC, I run following command from the command prompt on the CHANGED image (0xC is offset):

crc32wrt tl-wr1043nd-webflash_OK.bin 0xc

The old CRC32 I overwritten with the new one.

The new modified firmware must be flashed using working webupgrade version before build 33375.

The webupgrade now working again with the modified version.

Hello Jardosb,

could you change my file to ?
I tried it but I'm not able to, the upgrade process cancels always.

TP-WR841NDv8

Best regards

Yesterday i have noticed the same on my TP-Link WR1043ND v1.9.
I've also tried to copy the file via scp to /tmp.
The box reboots during the copy process.
Now i created a subfolder "test" under /tmp/.
I was now able to copy the file to /tmp/test.
It seem there is somthing wrong on the file system, because everytime a file is copied to /tmp (doesn't matter via scp or webfash ) the box reboots during the copy process.
Webflash with DDWRT header cause the same result.
I didn't flash manually because last 2 time i bricked my box 2 times and have to desolder the flashchip and reflash it outside.
b.t.w Webflash on TP-Link 942v2 is working perfect.

About TP-Link WR1043ND v1.9 i recon v1 and all its derivatives/versions are very outdated and obsolete...
a step to v2 or v3 is a giant leap forward...much more solid units with far better performance...excellent low class SOHO router...

I can confirm TL-WR941ND v3 bootloader size is 131072 (TPLINK string at 0x20000), so all BrainSlayer's commands are valid for this router.

I did it on MAC using SSH and SCP.
No need to download any additional tools.

Updated with build r36104.

Thanks.

I've been doing the same every release since last year (October maybe?) on a 1043NDv1, even somewhat automating the process with a script via the NAS mount.

I've been trying the webupgrade everytime without success. I guess it's one of those things I learned to accept that will never get fixed Smile

Could not unlock MTD device: fullflash

* reboot
Segmentation fault
Segmentation fault

-sh: /sbin/reboot: I/O error
SUPER GLUP**!!
* ls
Segmentation fault

Power off router and pray ... wait ... boot ... leds.... wlan ... led ...URL and got it with 34578 version and old config maintained


I've just killed my router by following this. It is missing the correct path! Should be:
dd if=/dev/mtdblock7 of=/tmp/boot.bin bs=1 count=131072
wget http://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2018/01-31-2018-r34777/tplink_tl-wr1043nd/factory-to-ddwrt.bin
cat factory-to-ddwrt.bin >> /tmp/boot.bin
mtd -f write /tmp/boot.bin fullflash

Without this /tmp/ (or cd /tmp/) this will irreversibly brick your router!

absolutely spot one sir!
worked like this 100%
wr941nd v3.6 had mtd7
