Download Winbox from Mikrotik webpage https://download2.mikrotik.com/routeros/winbox/3.11/winbox.exe
Boot up the RB750P r2, connect your DHCP client to any of the ports 2 to 5 but not the Internet labeled port (Port 1)
Open up Winbox, IP Address 192.168.88.1, If a password has been set put this in if not the Default is just Blank
Also, while we are in Winbox lets backup the license so returning to RouterOS is later possible. Go to:
System → Routerboard → Settings → License → Export key
System → Routerboard → Settings → Boot device: Try ethernet once then NAND System → Routerboard → Settings → Boot protocol: DHCP System → Routerboard → Settings → Force Backup Booter: Checked (if supported by your routerboard - !IMPORTANT) System → Shutdown
Connect the LAN port on Internet labled port and reboot the RB750P r2, Connect the computers LAN port on Internet
Please note that the aforementioned mechanism is not properly working on some boards. Don't worry, boot up the mikrotik board, connect your DHCP client to port 1. An address from 192.168.88.0/24 must be obtained. You can now telnet to the board, and configure it for TFTPboot.
Telnet user is
admin, leave the password empty.
telnet 192.168.88.1 system routerboard settings set boot-device=try-ethernet-once-then-nand system routerboard settings set boot-protocol=dhcp
Now reboot the board, it should boot from the labled “Internet” port now.
For Windows 10 x64 (7/XP/Vista should be ok)
Download http://tftpd32.jounin.net/tftpd32_download.html (i used tftpd64 portable edition) and the mikrotik-rb-nor-flash-16M-initramfs-kernel.bin and mikrotik-rb-nor-flash-16M-squashfs-sysupgrade.bin from Downloads above and then save them in the same tftpd32 folder IMPORTANT
Extract the tftpd32 folder and make sure ar71xx-mikrotik-rb-nor-flash-16M-initramfs-kernel.bin is there and open up tftp32 config file and match theses settings I have (worked for me)
4C:5E:0C:XX:XX:XX=192.168.1.250 (Should be the same ETH1 MAC Address) BootFile=lede-ar71xx-mikrotik-rb-nor-flash-16M-initramfs-kernel.bin Lease_NumLeases=2 IP_Pool=192.168.1.2 PoolSize=4 Mask=255.255.255.0 Gateway=192.168.1.1 Lease (minutes)=90
Open up tftpd64.exe and the go to Settings > GLOBAL and make sure, TFTP server and DHCP are ticked, everything else unticked, Save and Exit and then reopen tftpd64.exe for the saved changes!
Set a static IP on your Windows computer LAN port with the following
192.168.1.2 (Keep this to 192.168.1.2 or tftpd wont work **IMPORTANT**) 255.255.255.0 (**IMPORTANT**) 192.168.1.1 (**IMPORTANT**)
Follow method 1 to enable TFTP, Once done keep the LAN on port 1 (internet port) and then you should see something transferring and then the RB750r2 will boot into LEDE, Unplug the LAN port from Internet port 1 and set a DHCP on your Windows machine and then plug in the LAN port into any port 2-5 and the Internet port for a Cable Modem? Switch? Router? something that has internet access to it if you want to keep the LEDE on as this is in RAM mode and won't save any changes!
Now, If you want to erase you RouterOS then follow theses steps;
Log into SSH 192.168.1.1 with just root and password been blank (press enter)
cd /tmp wget http://downloads.lede-project.org/snapshots/targets/ar71xx/mikrotik/lede-ar71xx-mikrotik-rb-nor-flash-16M-squashfs-sysupgrade.bin mtd erase firmware mtd write -r lede-ar71xx-mikrotik-rb-nor-flash-16M-squashfs-sysupgrade.bin firmware
The device will reboot after flashing and will boot LEDE.
Or use sysupgrade over SSH
Load initframs like using TFTP like in step 1.
Only built in LEDE failsafe
If NetInstall gets stuck on Sending offer just wait for it to timeout and then close and open Netinstall again. Click on install again
In order for RouterOS to function properly, you need to restore license for the device. You can do that by including license in NetInstall
Ports 2-5 directly correspond to ports 2-5 as labeled on the unit, port 1 is the Internet (WAN) on the unit, 0 is the internal connection to the CPU.
