1. Baixe e descompacte o arquivo deaqui.

2. Baixe o firmware mais recente dosite oficiale renomeie-o para 'recovery.bin'.Nota: Você deve colocá-lo no mesmo arquivo das ferramentas do Tftpd.

4. Conecte seu computador à porta LAN do roteador com um cabo Ethernet.
5. Configure manualmente o endereço IP do seu computador como '192.168.1.88'.

Dear Customer,
Yes, you are right.
“OK, answer this myself (for TR3000 v1.0):
1. Find and download tftp32.exe
2. make directory “tftpboot”
3. put tftp32.exe AND the firmware (renamed to “recovery.bin”) into that directory
4. connect your PC to the LAN-port of the device
5. set your LAN IP to 192.168.1.88 like described here.
6. disable windows firewall (can do this with click and point in windows)
7. start tftp from the directory in step 2. and leave that window open
8. press reset-button on the device and then connect it to power/power on, keep pressed and wait, until it starts blinking/downloading the firmware to the device (in my case this was done after 3 seconds)
9. Enable firewall again, enable dynamic config (DHCP) on your lan port again, re-connect your lan and start to configure your Cudy device”

Sadly this does not work with my TR3000:
1. The download link (for tftp32?) is broken/does not work.
2. It doesn’t say where to put the sysupgrade firmware after download.
3. Does the sysupgrade firmware have to be renamed (to “recovery.bin”)?
Actually the stock vendor firmware for me is better/easier than open-wrt. So it should be possible to reflash to stock fw.
