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):
Router is essentially in a boot loop. Only Power and 2.4GHz are brightly lit.
The Putty log shows a number of SROM CRC errors. I have proper gear for (de)soldering SMD components but would rather use NAND reprogramming as a very last resort. Is it possible to import some sort of memory dump onto the NAND chip from the same unit? Or anything else I can do to fix the corruption?
Thanks all,

- Asus WebUI - hangs in all browsers during file upload
- Asus Recovery Tool - interrupts at around 32 Mb upload with an error message of a failed firmware upgrade
- Serial Recovery with Putty and TFTP 1 - router set in client mode - I/O error always at around 90-95% regardless of the file size
- Serial Recovery with Putty and TFTP 2 - router set in server mode - file transfer successful (any size) however router hangs afterwards and still doesn't work after manual restart
