Giải pháp của bạn đây, xin lỗi nhé mình bận quá không trực tiếp dịch cho bạn được :
You will need the program MTTY(Attached with this post).
1) Kill activesync processes: Ctrl+Shift+Esc in Windows to bring up Task Manager. Kill wcescomm.exe and WCESMgr.exe (by selecting the task on the processes tab, and clicking the End Process button below)
2) Phone needs to be POWER + Record + Pen Reset and on Serial/USB screen. COnnect it to the PC, and it should show USB, with the backlight remaining off.
3a) Run mtty1.42.exe
b) Select USB from first list (where COM1 is displayed. Don't press USB button). If USB (or a list item containing USB) isn't in the list, then you have't connected to the PC properly.
(Leave default parameters: 8 bits / Flow Control NONE / Stop bits 1 / Parity None / Local Echo No)
c) Click OK
3) Run following commands:
[press enter first to get USB> prompt]
USB>
5. type "set 14 0" without the quotes to tell bootloader to boot the OS after reset.
USB>set 14 0

7. type "task 0" to ask your device reboot

8) Exit the program, then re-hard-reset (POWER + Record + Pen Reset), leaving on USB screen in order to run ROM Flasher
9)Now be back to the Usb/Serial screen and run your favourite ROM upgrade-A clean installation
Please let me know if this worked for you too. I believe this was my great geeky work i did with my BA. Was so frustrated when the buttons were not
working.
P.S: This is not my own work. I got the Mtty app from this same forum and the steps too. I am terrible sorry if i have repeated a post or done something i should not
mtty 1.42.rar
