 +OpenWrt firmware images of previous releases can be found under the **ar71xx/generic** tree:
 +
 +  * [[http://downloads.openwrt.org/barrier_breaker/14.07/ar71xx/generic/|Barrier Breaker v14.07]]
 +  * [[http://downloads.openwrt.org/chaos_calmer/15.05/ar71xx/generic/|Chaos Calmer v15.05]]
 +
 +-> [[docs:guide-user:installation:generic.flashing|Install OpenWrt (generic explanation)]]
 +
 +Flashing OpwnWrt firmware is relatively straightforward. 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 ====
 +-> [[docs:guide-user:installation:generic.uninstall]]
 +
 +{{page>meta:infobox:dangerous&noheader&nofooter&noeditbtn}}
 +
 +With the TL-WA850/750RE router, there is a catch: The stock firmware is obtained from the OEM: [[http://www.tplink.com/en/support/download/?model=TL-WA750RE|TL-WA750RE]] [[http://www.tplink.com/en/support/download/?model=TL-WA850RE|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:
 +
 +<WRAP center round info 60%>
 +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.
 +</WRAP>
 +<WRAP center round alert 60%>
 +Flashing the wrong firmware **will brick the device** be prepared for it and don't commit unless you are.
 +</WRAP>
 +
 +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:
 +<code>
 +dd if=orig.bin of=tplink.bin skip=257 bs=512
 +</code>
 +
 +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:
 +<code>
 +sysupgrade /tmp/tplink.bin
 +</code>
 +
 +Or you use the mtd method:
 +<code>
 +mtd -r write /tmp/tplink.bin firmware
 +</code>
 +
 +OEM TP-Link firmware for the TL-WA750/TL-WA850 with the **//boot part removed//** to revert to the original OEM firmware:
 +  * TL-WA**//750//**re **//V1//** [[http://q.gs/6gidS|TL-WA750RE-V1-stripped.zip]]
 +  * TL-WA**//850//**re **//V1//** [[http://q.gs/6giY1|TL-WA850RE-V1-stripped.zip]]
 +
 +OEM TP-Link firmware for TL-WA850RE V2 original and stripped firmware:
 +  * TL-WA**//850//**re **//V2//** [[https://drive.google.com/open?id=1BfOSQu7-485_DzdfJfH9WisZA5dyMd6k|TL-WA850RE-V2-original.bin]]

 +==== Debricking ====
 +-> [[docs:guide-user:troubleshooting:generic.debrick|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

 +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.
