好久没有码过这么多字了,希望能帮到对刷机不太了解的同学。

Warning: 刷机有风险,变砖别打我 ^_^

简单来说就三步 - 降级firmware(支持telnet),改写CFE, 升级firmware。通俗的
讲,CFE相当于PC上的bios,firmware相当于windows,只要bios没问题,不管你是win7
还是win10都可以随便装

1. 下载资源
A). 工具合集:需要的工具和文件里面基本都有了

B). firmware
ASUS RT-AC68U Firmware version 3.0.0.4.376.3626
http://dlcdnet.asus.com/pub/ASUS/wireless/RT-AC68U/FW_RT_AC68U_30043763626.zip?_ga=1.226360538.1118235052.1479352894
Merlin 380.63
http://www.mediafire.com/file/37rpc5x32rtow5c/RT-AC68U_380.63_2.zip



2. 基本操作
A). NVRAM reset:
* Turn power off to the router by disconnecting the power cable & Wait 10
seconds
* Press and hold the WPS button & Restore power to router while continuing
to hold WPS button
* Continue to hold WPS button for 20 seconds then release WPS and wait till
the router fully boot
B). Enter Recovery Mode:
* Turn power off to the router by disconnecting the power cable & Wait 10
seconds
* Press and hold the RESET button & Restore power to router while continuing
to hold RESET button
* Continue to hold RESET button for 20 seconds then release RESET and wait
till the router fully boot



3. 具体步骤
A). 降级firmware
a). poweroff the router
b). disconnect internet of your pc,then connect pc to one of four ethernet
ports(yellow). set static ip, 192.168.29.2(if you are running Tmobile
firmware) or 192.168.1.2 (if you are already running Asus/Merlin firmware)
c). Enter router's recovery mode
d). install "Asus Restore Utility" then use "firmware restoration" to flash
the "TM-AC1900_3.0.0.4_376_1703-g0ffdbba.trx"
e). reboot router and NVRAM reset
f). from web browser, log on to router 192.168.29.1 and verify the firmware
version (skip the initial settings page, go to the main page directly)

B). 刷CFE(有风险,改/写cfe文件时候要小心)
a). enable telnet - on router's setting webpage, ADMINISTRATION > SYSTEM>
ENABLE TELNET> YES > APPLY
b). telnet logon - using putty (telnet connection) to logon 192.168.29.1
admin:password
c). plug usb drive to the usb2.0 port (black), from putty terminal type: ls
/tmp/mnt/*, remember the folder(usb drive) name listed, e.g., USB_NAME
d). extract stock cfe file from router to your flash drive: type cat /dev/
mtd0 > /tmp/mnt/USB_NAME/stock_cfe.bin
e). wait 15 sec, unplug flash drive, then plug it back to your pc
e). revise new cfe file (rt-ac68u_1.0.2.0_us.bin): open both stock_cfe.bin &
rt-ac68u_1.0.2.0_us.bin with "HxD Hex editor", copy 3 MAC addr and 1 WPS
code from stock_cfe.bin to rt-ac68u_1.0.2.0_us.bin, then save.(Details:
search "macaddr" and "secret" in stock_cfe.bin, you will find 3 "macaddr"
and 1 "secret_code" sections, replace corresponding parts in rt-ac68u_1.0.2.
0_us.bin with them, i.e., macaddr=XX:XX:XX:XX:XX:XX, secret_code=XXXXXXXX)
f). rename rt-ac68u_1.0.2.0_us.bin to new_cfe.bin and copy it to flash drive
, copy mtd-write to the flash drive as well
g). plug the flash drive back to the router
h). write the new cfe file back to the router: from putty's terminal type: /
tmp/mnt/USB_NAME/mtd-write -i /tmp/mnt/USB_NAME/new_cfe.bin -d boot
i). wait 15 sec, unplug flash drive, NVRAM reset, enable telnet, logon
router with putty, on terminal, verify cfe version (1.0.2.0) by typing:
nvram get bl_version

C). 升级firmware (与降级firmware一样,刷你想要的新版本就行了)
NOTE:router's ip would change to 192.168.1.1 after flashing Asus/Merlin
firmwares, user/pass may change to admin:admin
NOTE: for the first time, flashing 3.0.0.4.376.3626 is suggested to avoid
some problems on earlier versions of the router, then you can flash your
desired version directly in the future.
NOTE:it's easier to use router's setting webpage, ADMINISTRATION > SYSTEM >
FIRMWARE UPGRADE to flash the new firmware.
NOTE: NVRAM reset is suggested after every firmware flashing

GOOD LUCK~~~~~~~~~~~
