    Upgraded to 386.2_2 and Admin GUI does not display

    Known issue, also affects RT-AC68u. I found version 384.19 the most stable thus far.

    How can I monitor temperature on an AIMesh Node (merlin)?

    Hi all, I have done quite a substantial fan mod on my Asus RT-AC68u (circuit with temperature-control, driving 2x 12V fans with a separate power supply) and wanted to ask whether it is possible to monitor the temperature of an AIMesh node? Currently I can only see the main router. I'm on Merlin...

    Asus RT-AC68u losing AiMEsh connection post 384.19 Merlin firmware

    Hi guys, I just wanted to advise you that I have noticed that my Asus RT-AC68u keeps losing connection when connected as AiMEsh node in firmwares tested later than 384.19 and same thing happened to my RT-AC66u which I have now replaced with RT-AC88u. What happens is that the WAN port on the...

    Looking for a JTAG programmer with bundled software (Windows)

    Hi all, I'm now and then buying broken routers, fix them and sell them on eBay, giving net profits to charities - a bit of a hobby project of mine. The problem is that I cannot fix routers beyond hardware errors (i.e faulty components) and Serial TTL connections (TFTP uploads). Whenever I am...

    Asus RT-AC5300 soft brick recovery?

    Hi all, I got a broken Asus RT-AC5300 off eBay and after trying all the usual recovery methods (cleaning NVram and restarting router between each attempt as well as trying different LAN ports): Asus WebUI - hangs in all browsers during file upload Asus Recovery Tool - interrupts at around 32...

    JTAG vs Desoldering NAND?

    Yeah done that (this is how I found that half of that 10pin header was grounded). Cheers

    JTAG vs Desoldering NAND?

    Thanks, that's pretty much what I thought. I own couple of Asus RT-AC88u and the JTAG headers are clearly marked, 2 of them in total (5pin headers). I reckon the 10pin unmarked header between the WAN and LAN1 port is also JTAG as one of the rows is all ground. From my understanding all JTAG...

    JTAG vs Desoldering NAND?

    Morning guys, I wanted to ask you, if I successfully connected to a router through JTAG, can I reprogram the NAND or are there any limitations compared to desoldering the chip and accessing it through an external programmer?

    Looking for Putty boot log of a working RT-AC88u for troubleshooting purposes

    Hi guys, I'm trying to restore a couple of these units I got from eBay and was wondering whether anyone could share the boot log from Putty or similar, retrieved by serial / TTL / TFTP or similar connection methods from a healthy unit? If anyone got the full NAND dump, that would be equally...

    RT-AC88u: Failed to upload the firmware file transfer cancelled

    I have soldered the pins to access JTAG mode and my adapter is supposed to arrive later today. I'll share the log. I wonder if I can find a bootlog of a healthy RT-AC88u.. That would certainly help.

    RT-AC88u: Failed to upload the firmware file transfer cancelled

    Tried that, same result. Was there anything in the log file that you noticed?

    RT-AC88u: Failed to upload the firmware file transfer cancelled

    I got TTL cable from Amazon. All drivers are installed and COM ports are configured. I have connected to J3 socket on the motherboard. Since I managed to communicate with the router, I am fairly confident the connection is stable. I connected the LAN cable to port2 on the router since ports 1...

    Yes, WPS reset works fine, so does the Rescue mode and miniCFE web portal

    RT-AC88u: Failed to upload the firmware file transfer cancelled

    I actually managed to upload the latest Merlin firmware through TFTP and it was a success. Did NVRAM wipe afterwards, restarted the router and it keeps rebooting itself. I flashed stock firmware (same version as was on the router according to the label on the bottom, i.e 3.0.0.4.380) to nflash1...

    RT-AC88u: Failed to upload the firmware file transfer cancelled

    Oh that is some excellent insight! Many thanks. So I need then to figure out how to bypass that fake limitation
