 +{{page>meta:infobox:dangerous&noheader&nofooter&noeditbtn}} 
 + 
 +With the TL-WR842ND router, there is a catch: the stock firmware is obtained from the OEM: [[http://www.tplink.com/en/support/download/?model=TL-WA850RE|TL-WA850]] [[http://www.tplink.com/en/support/download/?model=TL-WA750RE|TL-WA870]] 
 + 
 +  * 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: 
 + 
 + 
 +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-WDR3500 with the **//boot part removed//** to revert to the original OEM firmware: 
 +  * TL-WA**//850//**re **//V1//** [[http://q.gs/6giY1|TL-WA850RE-V1-stripped.zip]] 
 +  * TL-WA**//750//**re **//V1//** [[http://q.gs/6gidS|TL-WA750RE-V1-stripped.zip]]

 +ART = Atheros Radio Test - it contains RF calibration data for the wifi. If it is missing or corrupt, wireless won't come up anymore.\\
