hey guys, so i've been thinking of updating my phone to the latest firmware, but the problem is that my USB port doesn't work very well. It takes me 10 to 15 mins to get the phone to start charging or connected to the computer. Sony won't repair the damn thing cause of excessive damage. I need to know if i can safely update without flashing FTF files which include the kernel. I also tried going to pure stock directly from Sony, but PC companion won't restore the phone since i'm on a custom ROM (Existenz Ultra 5). Can any provide me with the PCC firmware file of the latest release? or any other help would do.
Also, i cant enter flash mode since the port is damaged.
Sony PCC says it doesn't have any software for my phone even when i click the restore button.
