Hi,all
Most phones made in china are using MTK platform.MTK platform is very cheap and highly integrated!
You can download more data or tools here: ftp://study-bbs.com:study-bbs0304@220.113.15.15
Directory names and file names are in chinese,but most datasheets are in english.
I'll give you some hints for understanding these chinese words.
At the home directory of this ftp account,it may looks like this:
