I have flashed this thing so many times :).... I am officially a flasher.
I can restore to the stock firmware.
I have flashed version 17 using TFTP but it just brings up the router with the green light and it is stuck. I cannot reach it by IP.
What is m8?
I am going to try to reduce the bin name. However, I already flashed the system with the OpenWRT factory file and it won't work. The router just gets stuck.
I install the factory bin.
My only problem is after that.
I am going to install the factory bin and then go through tplink to flash the openwrt file with version 17 to see if it will work with a shorter filename. I am not holding much hope here because it has not worked using TFTP. I have no clue what to do :).
After I restore the stock fw with tftp, I get an invalid file error in tplink.
This is where I get the factory bin that works for me on TFTP. It takes me to tplink interface.
Then I go here
Click firmware and I can download the file.
That works for me to bring the router back to life :).
Now, not sure what to do. Going to try shortening the name here in 5 mins.
From here seems that will be easier you rebuild your local user script that the new openwrt "broke". Also, a new firmware (and kernel) support a lot of new cool stuffs, like firewall4 instead firewall3.
I also dunno how to help, if the old desired version factory doesn't work. Maybe the new stock fw is preventing the openwrt install -- like, when factory.bin for v17 was made, the stock fw was an older version that allows openwrt install.
Maybe searching a really old stock fw version at your risk... but I would spend my time in that broke script.
