Hi guys, could use some help as well.. TS sorry for the tumpang thread.
My bro accidentally (He never bothers reading when it pops up telling him iTunes will be upgrading his iphone to 2.0 zzz) upgrades his firmwares to 2.0 so I googled around and manage to solve downgrade it to 1.1.4
now the major problem i'm facing is, after the downgrading, I have difficulties syncing the bloody phone with my PC. When i plug the phone in, usually at device manager u should be able to see the phone is synced (either its iPhone or Storage device) but its not showing anything! Even the phone is not charging. Before I perform the downgrade, it was working fine.
I myself am using iPhone, so i did some basic troubleshooting by:-
1. testing whether is it the cable problem, and it works fine with my iphone.
2. Could be iTunes corrupted or something, so reinstalled the whole iTunes (Currently running 7.5) for downgrading purposes.
3. USB port faulty, changed to another 2 ports, still not working.
4. PC Problem? Changed to 3 different PCs, still the same..
Googled like mad for the past few days and tried all the things I managed to find but still the same.. Could really use some help from u guys if u guys ever encounter such issue...
Thanks in advance!
Note: The iPhone is working fine, I can access Wifi, can surf net using wifi, but Installer.app is not installed so I can't install anything.
