before you reflash you need to make backup....i suggest you use default backup rather than backupmenu....backup all contents then reflash....since you wanna start from scratch then after reflash do restoration from your backup...exclude the application list (so HAM wont install app/program automatic on your device)


Ok...first thing that you really need to install is after reflash.....

1.rootsh or sudoer....

Then install....

2.Faster Applications Manager

since you have restore backup then you dont need to input manually all the repo in FAM or HAM anymore....

now we going to the main installation...you want CSSU on your device or not???
if you do then downloads the CSSU here then copy it to you device...open the files you have download using file manager & let HAM do the rest....
if you already know about CSSU (install it before) then you know what step you need to do next....

After installing CSSU then reboot your device....after reboot open FAM (faster applications manager),update all repo then installed....

3.filebox
4.kernel power 48
5.enhanced busybox
6.libqtm-11 & libqtm-12 (under categories/advanced)
7.mscp
8.CSSU features configuration
9.Theme customizer (do not install CSSU tuner)

number 6 & 7 is critical to install first if you want to install apps likes fMobi or Kaspovus later on.....
now the rest it up to you to install whatever apps/program you needed...remember to install what you really needed only...

those were my step right after i have flash my devices....now my device got no problem...no more white/black screen bug on fMobi & kaspovus and much more....

regarding about installation space it is all depends on how much you wanna install apps/program on your device....
