Hi, i have a hair pulling situation. after i flash my TP-Link WR-1043ND to the latest dd-wrt firmware, now it just keeps on rebooting in loops. any help please?

I have recently gotten into this situation as well.
My router (1043ND) was on build 14289 when i attempted to reset the router.
After reseting the router, the router was rebooting in loops.
I have tried reseting again or getting the router into failsafe mode but to no avail.
The router reboots very quickly, around 1 second after my computer detects it.

So anyone has any idea of fixing it without the need of opening the router or soldering any wires to it?

Exactly Same, after restart!
I have not found another way to how to recover (no way to use some failsafe mode).
So I used DCA-510 cable (for siemens,which i found at home)and attached with tape and needles (thats very hard without soldering ) to router serial and then recover with serial console and tftp.




Here are the steps:

1. Download modified original firmware that has first 0x20200 cut off, or use firmware attached below.
2. Gain access to the serial port and hook it up to your computer using RS-232 / USB --> TTL adapter.
3. Install Putty, setup Serial connection, set COM port appropiately to your adapter in step 2 and do not click Open yet
4. set networkcard of computer to ip address: 192.168.0.5 , subnetmask 255.255.255.0 and no gateway
5. Install TFTP32 server (google it) on your computer, connect computer with ethernet cable to LAN switch port on router.
6. Make sure the "Current Directory" in TFTP32 is set to folder with modified original firmware renamed to "code.bin"
7. In Putty, click open and plug in Power cord to router... you should see bootloader coming up now...
8. You will see something like this:

No valid address in Flash. Using fixed address
: cfg1 0xf cfg2 0x7114
eth0 up
eth0
Autobooting in 1 seconds## Booting image bf0200000...

Then type following fast: tpl

Now you will get into the command prompt and you're able to execute commands.

9. Erase the firmware before writing it again using following command: erase 0xbf020000 +7c0000
10. Download new modified original firmware from computer to the router: tftpboot 0x81000000 code.bin
11. Write the downloaded firmware to flash using: cp.b 0x81000000 0xbf020000 0x7c0000
12. Boot the original firmware again: bootm 0xbf020000

Your router should be unbricked again!

Hi - can you attach the firmware pls? I got a bricked wr1043n grr

You can use original tp-link firmware without "boot" in filename http://www.tp-link.com/common/getresource/?type=Firmware&resource=201082817292310.zip

Could you specify your selected settings at BAUD Speed and error connection ?

I'm not getting any output on COM-Console at Router plugin to charger. I am using a ProfiLic PL-2303HX-Chip USB-RS232 Adapter shown here http://www.stkaiser.de/anleitung/data/01d_usb_unboxed.html

My connection is done like this.
Either a exchange of RX&TX doesn't establish a connection to the console.


Compared to your picture I never had a R363 installed on my Board Version. I checked connectivity with a beeper.

The USB RS232 TTL Adapter works fine as I recently patched a ARCOR-DSL WLAN-Modem 100 to ZyXEL Prestige P660HW-67. Acording to the Serial Wikipage the chip used in the adapter is able to do the job. Still no connection.

Device behaviour is basically when the light flashs as follows after pluged in:
1) PWR (4 seconds no change)
2) ALL Lights (for 1 second)
3) Back to 1 at PWR (1 second)
in a selfrepeating loop

Thank you all for your great Help. I successfuly fixed it. I needed to bridge the missing R363. Then the Console came up as hoped for.

Thank you everyone who posted in this thread!!!
I have successfully fixed it using a ca-42 cable ordered from ebay and stuck it to the router with tape
Again, thank you all!!

I'm about to attempt this fix with an old USB to serial cable.

Were you guys able to flash DDWRT onto your 1043ND after un-bricking?

Hi,
I just tried firmware factory-to-ddwrt.bin (37305) and as a result boot loop occurred. I reverted quickly using Tftpd and http://www.friedzombie.com/tplink-stripped-firmware/
just run server pointing to stripped firmware on 192.168.0.66, and plugged power with reset button pressed.

Than I tried again with build 36698, same situation.
It worked with build 36104.

If it doesn't work on a specific build, then post something in the build threads. For example, for 37882: https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=317688

I have a 1043ND v1.8 but it is currently perma-bricked. I can't even get a serial connection from it.
