What I've Learnt

1. FDL1 and FLD2 are flashed to the ram to allow flashing other partitions. These two are like micro kernels that allow EDL communication etc.
2. U2S or Usb 2 Serial Diag allow serial communication but that only stays active for a few seconds, you need to activate diag mode to flash FDL
3. CM2SP3 is the latest version of CM2SPD CM2SP CM2SP2 tools. It does not come with the boot
4. Spreadtrum T760 has the same as SC9620 (Check the CM2SP3_234b2.7z from CM2SP3 it has the boot files, also check firmware unlock by TomKing)

[main]
soc=T760
link=SoC\sc9620

6. .pac files are firmware files that
