DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version 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 has ended in 2022. 19.07.10 was the last official build for 4/32 devices. The TL-WA860RE, TL-WA854RE, 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) Supported Versions Brand↓ ModelVersionCurrent ReleaseOEM InfoForum TopicTechnical DataTP-LinkTL-WA750REv118.06.9https://www.tp-link.com/us/home-networking/range-extender/tl-wa750re/https://forum.openwrt.org/t/report-devices-here-with-18-06-0-provided-image-too-big-to-save-overlay/18161/72?u=tmomas, https://forum.openwrt.org/viewtopic.php?id=46859View/Edit dataTP-LinkTL-WA850REv118.06.9http://www.tp-link.com/en/download/TL-WA850RE_V1.htmlhttps://forum.openwrt.org/viewtopic.php?id=46859View/Edit dataTP-LinkTL-WA850REv218.06.9https://www.tp-link.com/en/products/details/TL-WA850RE.htmlhttps://forum.openwrt.org/t/report-devices-here-with-18-06-0-provided-image-too-big-to-save-overlay/18161/72?u=tmomasView/Edit dataTP-LinkTL-WA860REv1 (EU)18.06.9http://www.tp-link.com/en/products/details/cat-10_TL-WA860RE.htmlView/Edit data Model Version Launch Date OpenWrt Version Supported Model Specific Notes TL-WA750RE v1 2013-04 BB (r38719) AP123 Model Version Launch Date OpenWrt Version Supported Model Specific Notes TL-WA850RE v1 2012-12 BB (r38719) AP123 TL-WA850RE v1.2 (UK) 2013-06 ?

All you have to do is to access the GUI page (192.68.0.254) of the device via Ethernet or Wifi, navigate to 'System Tools' > 'Firmware Upgrade', upload your OpenWrt installation image and click 'Upgrade'. Back to stock firmware → generic.uninstall Warning! This section describes actions that might damage your device or firmware. Proceed with care! With the TL-WA850/750RE router, there is a catch: The stock firmware is obtained from the OEM: TL-WA750RE TL-WA850RE In case the file name of this firmware file does not contain the word “boot” in it, you can simply revert back to original firmware In case the file name of this firmware file does contain the word “boot” in it, you need to cut off parts of the image file before flashing it: These days it is not necessary that the word boot is included in the name. If the original firmware doesn't revert to stock. Strip it and flash it again. Flashing the wrong firmware will brick the device be prepared for it and don't commit unless you are. An example of an image file with the word “boot” in it is wa850rev1_en_3_14_8_up_boot(140310).bin. Cut the first 0x20200 (that is 131,584 = 257*512) Bytes from original firmware: dd if=orig.bin of=tplink.bin skip=257 bs=512 You should transfer the firmeware image to the /tmp folder and revert back to original firmware (if availlable you can flash the firmware via the webinterface as well): Via the safer method using sysupgrade: sysupgrade /tmp/tplink.bin Or you use the mtd method: mtd -r write /tmp/tplink.bin firmware OEM TP-Link firmware for the TL-WA750/TL-WA850 with the boot part removed to revert to the original OEM firmware: TL-WA750re V1 TL-WA750RE-V1-stripped.zip TL-WA850re V1 TL-WA850RE-V1-stripped.zip OEM TP-Link firmware for TL-WA850RE V2 original and stripped firmware: TL-WA850re V2 TL-WA850RE-V2-original.bin TL-WA850re V2 TL-WA850RE-V2-stripped.bin Debricking → generic.debrick Some success with WA850-REv2 was made, follow this forum thread: https://forum.openwrt.org/t/tp-link-wa850re-v2-0-bricked/35515/37 Click to display ⇲ Click to hide ⇱ To quote tp-linkuser: 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: 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). setenv serverip 192.168.1.10 tftpboot 0x80060000 firm.bin erase 0x9f020000 +0x380004 cp.b 0x80060000 0x9f020000 0x380004 bootm 0x9f020000 Note: According 6 to printenv (TL-WA850re v2 - Too big uncompressed stream LZMA ERROR 1 6) or typing printenv for info.

Opening this device exposes parts under high voltage (110/230 VAC)! Risk of deadly electrical shock Risk of irreversable damage to other components attached, e.g. your PC connected via serial Make sure to keep your fingers, conductive tools and serial cables away from the high voltage at all times! Capacitors can still retain dangerous voltages after disconnection from mains! Continue at your own risk! Note: The case doesn't have any screws, but instead is ultrasonic welded together.
