This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram. DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version (18.06 or later) onto it! See 4/32 warning for details.
1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation.
This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now.
2) OpenWrt support for this device will end after 2019.
19.07 will be the last official build for 4/32 devices. After 19.07, no further OpenWrt images will be built for 4/32 devices. See OpenWrt on 4/32 devices what you can do now.
The TL-WA860RE, TL-WA850RE and TL750RE were great because of their miniature size and wall-mounted design
TL-WA750RE is a 10/100 Ethernet b/g/n 150M (one on-board printed antenna)
TL-WA850RE is a 10/100 Ethernet b/g/n 300M (two on-board printed antennas)
TL-WA860RE is a 10/100 Ethernet b/g/n 300M (two external non-removable antennas and AC passthrough)
I have been able to restore it :smiley:, but with firmware openwrt 18.06.5 sysupgrade. I think that with stock firmware is also restorable.
NOTE: I can't save the config settings with openwrt, erase all turning off the device.
You have to bridge 2 points (try it first with Tx and test it, after Rx).
Note: you'll need usb to rs232 ttl converter module, pins working at 3.3V (TTL level voltage).
Setting ip pc to 192.168.1.10, run tftp server (tftpd32 4) on ethernet interface, download lastest firmware openwrt 18.06.5 sysupgrade version, rename to firm.bin (for easy use).
Note: data (firmware) is sent on ethernet interface, commands are sent on serial interface UART.
Note: openwrt 18.06.5 sysupgrade 2
Setting baud rate to 115200 (PuTTY console), no flow control.
Note: I have stopped loop with typing tpl.
In my case setting to 128000 can see characters but not stop loop.I have stopped loop, setting baud rate to 115200 and only connecting Rx on device (repeater). Because if connect Tx too, i can see rare >characters, and cant use ctrl-v, which interfere with ctrl-v.
Conclusion I did it without seeing. :unamused: :pensive:
During “Autobooting in 1 seconds” type tpl.
Note: open notepad, typing tpl, select it all, copy for use it into console (PuTTY) with click right or ctrl-v.
set where to find for file firm.bin
copy firm.bin from tftp to ram memory (0x80060000 address).
erase 0x380004 (3670020 Bytes) from flash memory (starting at 0x9f020000).
copy firm.bin stored in ram to flash memory (0x380004 Bytes).
boot from flash memory (0x9f020000 address).
