 |
Hey Guys,
A few months ago, I saved up and purchased a new Archer C5 1.20 (TP-Link AC1200) from NewEgg. Once it arrived, I flashed it with the latest stable OpenWRT and it worked well. A couple of months later, I saw there was an updated OpenWRT firmware and decided to upgrade, but when doing so, carelessly flashed it with the firmware to be used from stock - not the upgrade version.
Now, I know what you may be saying and I get it - I used OpenWRT originally - not DD-WRT. I get it. The problem is that no one in OpenWRT's forums seems to be able to help so far. As I use DD-WRT on some other routers, I know how similar they can be - plus- your forums are so much better and have been trying to restore with DD-WRT, so wanted to post here, too.
The Issue
Since flashing the wrong firmware, the router goes into an infinite boot loop each time I power it on. 
I have spent hours, upon hours, upon hours trying to un-brick it. Many times I have felt I've come close, but can't seal the deal. Currently, I'm trying two different methods and have hit a roadblock on both. Details for each are below. If you have any suggestions, please let me know...
De-brick Method #1 of 2: Load Firmware via TFTP
Process Following
1. Attach router's LAN 1 port to PC and set PC to 192.168.0.66
2. Load TFTP and have firmware in it named "ArcherC5v1_tp_recovery.bin"
3. Hold down WPS button on router, power it on, wait until WPS light comes on (~5-6 seconds) then let go of WPS button
Result
I have the router connected via serial -> USB at the same time so can watch what happens. The echo from the latest attempt today is below. Seemingly, I have the wrong firmware, but have tried at least 30 including ones with boot, pre-stripped ones, factory ones, openwrt, ddwrt versions, plus ones for archer c7 - all with the same result
Exmaple of pre-stripped one I tried: http://www.friedzombie.com/tplink-stripped-firmware/

De-brick Method #2 of 2: Load Firmware Over Serial
Process Followed
1. Connect router to serial -> usb adapter and plug into laptop
2. Ensure driver is correctly loaded (Win10x64)
3. Launch Putty on COM port assigned using 115200/8/N/1/Flow Control Off
4. Boot Router
5. Constantly type "tpl" then enter to break the boot
Result
Everything initially works. I get the echo from the router's boot (shown below) and see it loop. The issue is that I can type "tpl" then enter (on keyboard with putty console open, typing the t, p, l, then enter keys) 1000 times and cannot break the boot to get a prompt. I've tried starting it from the moment I power on the router and even wrote a script that would send "tpl" enter every 200ms which I started after booting the router without luck.
I looked up other common "break" commands, but none worked. Below's the echo I get when simply powering on the router currently...

So - any suggestions? I've invested so much time in it that it's no longer about getting my money back; but more of a challenge.
Please help! |
