Hello,
Please help, I need to revert to the original firmware.
TP-Link TL-MR3220 V2

Thank you

[Malachi]

This is taken from openwrt:

The following procedure was tested with a Version V2 of TL-MR3220.
Enter failsafe mode:

remove the power plug from the router
press and hold the RESET button
insert the power plug
release the RESET button
Some seconds later no LED besides the one for USB (and maybe for attached ethernet ports) should be lit.

The device now uses the IP 192.168.0.86. It repeatedly tries to download a file named mr3220v2_tp_recovery.bin from a tftpd server with the IP 192.168.0.66. You can verify these continuous requests even from logviewer of your TFTP server like Tftpd32 or with a network sniffer (e.g. tcpdump or wireshark).

Given below is log taken the logviewer of opensource TFTP server Tftpd32

Rcvd DHCP Rqst Msg for IP 0.0.0.0, Mac 48:88:CA:27:00:06 [08/06 14:10:28.790] Connection received from 192.168.0.86 on port 1890 [08/06 14:11:45.055] Read request for file <mr3220v2_tp_recovery.bin>. Mode octet [08/06 14:11:45.076]

For MR3320 v2, Please use the filename “mr3220v2_tp_recovery.bin” (squashfs, not sysupgrade), connect to LAN, not WAN. Press and hold WDS/RESET, power on, the WDS-LED (padlock) lights up.

After some time you will see all LEDs flashing once followed by a normal restart of the router.

Change the name of the stock firmware to mr3220v2_tp_recovery.bin
