SE K550i backup

[thexplanet]

Hello All,

I had just purchased a SE k550i recently, and i joined the best TopSony forums, as i had gone through all the threads within this forum.

I am eager to flash my k550i to w610i firmware.
however, i need to be able to rollback to my original state (that's k550i)
so, do i need to take a GDFS backup, or Firmware, or Main backup.

or only GDFS would suffice.

as i dont want to brick my new k550i, so please help me so i can take the correct steps, in terms of backing up the files.

please specify which one is most important.

Thanks in advance

You only need to make GDFS backup before you do somethin to your phone, ie. before flashing your phone to W610, before patching your phone (when it's flashed already to W610)
The most important to know is always make GDFS backup before doing something to your phone so you can fix it whenever you do sumthin wrong.
Cheers...

if you use xs++ when cid appear you backup choose gdfs backup.
