I've buy Acer DX900 recently and after 2 weeks use this phone i found that the battery only can b e used for half day. So, i surf the web to find the solution and i get some information that i must:
a. install a new ROM,
b. upgrade my 3G modem (This file can be founded in your new ROM folder)
c. installing new firmware for the battery.
The main problem is when i want to install my new ROM, one error appear say that "No USB Connect Detected".
After browsing some forum, i found the solution for installing new ROM. I post it here for my guidance in the future.Thanks to eten-users . I also make an modification in certain steps from the original post.
For b. and c. above, i can install it easily by following the manual attached in the downloaded file.
Files to use:
