TP-LINK TL-WR841nd v9 30dBm hack

Hi, I'm new to openwrt, I want to be able to unlock my wr841nd v9 to get 30dbm of power, reading in detail in the step of:
"Upload artHACKED.bin downloaded from the official guide to / tmp /"
I don't know where "a / tmp /" is, could you please access me!

Here how to unlock 30dbm WR841N/ND V9
(The official guide ART unlocked firmware is uboot unlocked not art)

  1. (Skip if you have installed open wrt already)
    -- Flash official openwrt-15.05.1-ar71xx-generic-tl-wr841n-v9-squashfs-factory.bin
    -- Flash official openwrt-15.05.1-ar71xx-generic-tl-wr841n-v9-squashfs-sysupgrade.bin

  2. Having open wrt official working, flash firmware via lucy compiled by me with ART UNLOCKED
    drive google com /file/d/1mMn8CMNaT6ULBCLwpoekR99ypEPUoXFU/view
    and wait router reboot

NOTE: Dunno why, but lucy web interface giving connection refused via web, dont care.

  1. Make SCP connection to router like this (WinSCP for windows users):

Official artHACKED.bin image: drive google com/file/d/0B04Rm7S5I3txejBUS2tpcXNxeTQ/view

Upload artHACKED.bin downloaded from official guide to /tmp/

  1. Make ssh connection (For example with Putty in windows) and run:

mtd -r write /tmp/artHACKED.bin art

#Wait for router reboot

  1. After router reboot

A) Make connection via SCP to router, upload official openwrt-15.05.1-ar71xx-generic-tl-wr841n-v9-squashfs-sysupgrade.bin firmware with name flas.bin to /tmp

B) Make ssh connection with putty and execute:

cd /tmp
sysupgrade flas.bin

#Wait for router to flash oficial firmware and reboot
#Country US , you will have to 30dbm

###Final notes
With 30dbm i have stronger signal in my room, with 21dbm had only 5mb connection enougth for browser, now 36 mb.
In places where there was no connection, now can watch youtube videos smoothly.

Thanks to open wrt. I was in ddwrt and was for killing that router. Had to reset every some days. Now all go fine.

Hi. do you have a firmware download? the link is not valid :frowning: Thanks
