Dear All,
事情起因，小弟一時不察買了一台鎖機的 ET-747 IP PHONE，
爬了各大網站，在友站論壇上有高手討論，但境界太高了，還是看不懂！
希望有高手能將 無鎖機韌體傳送給小弟 or 直接教我如何破解？
因功力不高，不要寫得太艱深，謝謝！
弟David 敬上

執行時選anonymous帳號，把韌體放到Home Directory內。
連到et-747的設定網頁，把網址改成ftp的位置，檔名改成
和韌體相同。
試試吧。
如果分享器有擋ftp，記得去開啟它。
若ftp還不行或刷出問題再改用下面方法,記得把pc的ip位置改一下.
記得直接用條網路線連接。

解壓縮後，把韌體放在一起，執行tftpd32.exe
15. 如何重寫E(M)T747程序？
15．如果在電話LCD屏幕上看到「Upgrade Fail」的字樣，請按照如下步驟恢復程序。
1．建立一個TFTP服務器
2．您的計算機配置為TFTP服務器地址，如：
IP: 192.168.0.250
Mask: 255.255.255.0
Gateway: 192.168.0.254
3．軟件名：Emg202s40.bin.gz
4. 將軟件放入您的TFTP服務器中
5．將TFTP服務器的網口與電話的WAN Port連接
6．接通電話的電源然後自動進入程序的恢復中。
