OK, that is very interesting!
ThereŽs another possibility to make a backup:
you need SP Flash tool: chinamobiles.org/attachment.php?attachmentid=23720&d=1354147322
and MTK droid tools: http://chinamobiles.org/downloads.php?do=file&id=733
Open MTK droid tools, connect booted phone in Android and click on "blocks map". Switch to full screen mode and make a shortcut copy of all the shown datas. Best: Print that page, youŽll need it later.
Close MTK droid tools again.
Go to read back and remove all entries if there are any.
Click an "add".
Double-click on entry. Change name "ROM_0" to first entry of you printed list, i.e. "PRELOADER".
in next window let "HEX" and enter start adress and length of the list in HEX format (starts always with 0x...)
i.e. PRELOADER start adress 0x0, length 0x40000.
repeat "add" with all entries like DSP_BL, MBR, EBR1, PMT... in my example 19 entries.
Take care that all adresses and lenghts are correct!
at least push "read back"
SP Flash tool will create a backup.
