I have the same device. I put firmware on it and started to use OpenWrt. It was very nice first round, However later I wanted to put another firmware which I understood updated snapshot (openwrt-ramips-mt76x8-tplink_re305-v1-squashfs-sysupgrade) and device didn't like i.t It started continuously rebooting when I put in plug, there is no connection on http or telnet etc.
So I feel I messed up firmware/flash room things..
Now, want to fix it, I have a Raspberry Pi 2 and v 3 and some little cables.... Also windows machine and if necessary I can buy usb 2032 things too..
On this image,
where is Ground, TX, RX, connections and what's their order? Is there anyone able to help me out? Don't want to throw this device and hoping to learn and experience...
Any advice for me? If so, what steps should I follow?
I appreciate your help.
Snapshots never come with a webui, and telnet haven't been enabled in years.
thank you for your answer. I'm not able to connect to device with http telnet ssh etc. after second firmware update, device crashed & restarting continuously... I'm looking raspi serial connection and reinstall first firmware again. However I really don't know which part https://forum.openwrt.org/uploads/default/original/3X/5/c/5c12b2e154ee0cf7e352376c1e43f5af9fab3b93.jpeg I need to connect as a TX, RX, Ground... do you have any suggession?
I'd say the 2nd from the top is GND, RX and TX are below, which one's which's trial and error.
hi Frollic, thank you for your answer again.
If I trial and error.. is that possible to burn this board?
How can I be sure I'm doing right?
You can always use a multimeter to be sure about the plus and GND.
Accidently connecting TX to TX and RX to RX won't destroy anything.
thank you so much for your answer! I'll try and let you know about my result
It's not unusual for tp-link to cripple the serial port access, you might need to do some additional soldering, to actually get a working connection.
Hello. Has anyone found a solution about re305v1. I bricked mine and dont know how to unbrick it. Found out that tftp server is not supported on this device..so the only way is to instal the firmware by serial??
if you do I would like a photo from the connection... thanksssss
that would be the 2nd from the top, yes ....
hello there.... i wanna help for re305

I have managed to connect to the device with the J2 port and a USB-TTL adapter. I share information that may be useful to you.
Connect via serial:
screen /dev/ttyUSB0 57600
Press 2 on the menu and flash OpenWRT sysupgrade (other images don't work) using TFTP.
