Flashing instructions :
Am getting few PMs on how to flash A75. Thought I would post it as a separate thread to avoid confusion.
Flash files - Www.sendspace.com/file/19ma4k
Here is the link for the s/w ( a previous version of wat we downloaded.)
Please follow this method to flash.
Install the drivers given in the forum. (The MT65x3 folder - Install driver file). Then restart the system.
Driver file: You can download drivers from here:
Run SP flash tool. Choose the scatter file (MT6573_Android_scatter.txt) and Downloading agent (MTK_AllInOne_DA.bin).
Untick PRELOADER.
Then run Download. ( if file not found error comes, choose each file individally DSP_BL, UBOOT etc..)
When the s/w scans for the phone, plug in the phone(switched off).
Flashing complete.
I will recommend ppl to use ROM -> UB-A75-1 it is much better
