Deleting root directory
Is it possible to erase the entire "\root directory" content on the iPhone through WinSCP?
I'm trying to get rid of an underlying WiFi problem I've had ever since using jailbreakme back in the summer.
Often when unlocking the phone, it will say it's connected to my wifi network, which it is but won't have internet access.
Entering these details in manually instead of using DHCP makes no difference.
Even when resetting the phone under settings to start a fresh, upgrading to 4.1 using l1merain made no difference.
I'm thinking one of the original sys files which handles the connectivity layer of my iphone is corrupt in some way.
Would erasing the entire root directory still kick the phone into DFU mode?
This is a wrong way to fixing your problem.
perhaps the wifi issue is related to your wifi router and not the phone.
you obviously had 4.0 and 4.1 firmware and you still having the same problem.
If it's not your wifi router then the hardware may have a physical defect.
Take it to your Apple store.
