Hi guys, just to share this out.
If you wanted to go back to the original ROM, here's a link to get this. This rom is developed by Foxconn for Commtiva Z71. It worked for CSL Spice Mi300 as well. Those who got original Android 2.1 or wanted to get back to the original rom, you might wanna consider this.
Built-in Additional features:
-Interactive lock screen
-Stock Froyo Interface
-New Phone App Interface
-File Manager
-Google Apps
-E-compass
-My Scene (something like Theme Manager)
-"Welcome" and Android Logo Boot Animation
-Some apps worked better
This is the Stock Foxconn Froyo ROM and IT IS NOT ROOTED. You can try z4root/Universal Androot/SuperOneClick. No CWM/Rom Manager/Superuser etc. installed. It is recommended to do a full wipe before installing this ROM.
Those who wanted to update from 2.1 to 2.2, this is the best ROM so far. There is a nb0 file inside and you might need Clockworkmod Recovery for rooted phones and for those who does not, use Software Update Tool and boot into Download mode by pressing End Call + Vol Up + Power.
