How to remove installed patches?
Just repeat 2-7 steps. When you will see the list of patches in your phone, just select unwanted and press delete button (or F8). Click on two dots, wait until FAR manager will delete unwanted patch and exit the phone file system. Second method - just reflash main (mbn file) of your phone - it will remove all installed patches.
