With the TL-WA850/750RE router, there is a catch: The stock firmware is obtained from the OEM: TL-WA750RE TL-WA850RE
Note: 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.
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:
Or you use the mtd method:
mtd -r write /tmp/tplink.bin firmware
