iPhone 6 and 6 Plus Can Not Receive Remote Push Notifications - ios

Question

I have a really strange problem with my app on iPhone 6 and 6 Plus (iOS 8.2). I've followed and read almost everything (I Think!) that I found on the web to figure this out, but still it doesn't work. I've tested the app on iPhone 4 (iOS 7.1), 4s (iOS 7.1), 5s (iOS 8.1) and iPad Mini (iOS 8.2) and they all can receive the push notifications on from the app. My XCode version is 6.2 and the iPhone 6 devices (iOS 8.2) are detected as ineligible devices on it. So I can't even run the app right from XCode.
I'm using php script to push the notifications. When the app first run on iPhone 6, it showed up a pop up alert asking for the push notification permission. On the device's settings, the app is there on the notifications settings. I've tried revoking the apns certificate and creating a new one, re-generating the .pem files, reseting the device contents and settings, uninstall and install the app. None of these ever worked and I am already pulling my hair out. I even asked the Apple technical support for this but their answer is really just blah. I've tried downloading an app from the app store that has push notifications feature. And somewhat the device can receive push notifications from that app. So, is there anything that I am missing here? Can someone help me in this?
As suggested, here's my code for registering the notifications. I called the method "registerForRemoteNotification" from inside "application:didFinishLaunchingWithOptions:" :
- (void)registerForRemoteNotification
{
if ([[UIApplication sharedApplication] respondsToSelector:#selector(registerUserNotificationSettings:)])
{
NSLog(#"system version >= 8.0");
UIUserNotificationType types = UIUserNotificationTypeSound | UIUserNotificationTypeBadge | UIUserNotificationTypeAlert;
UIUserNotificationSettings *notificationSettings = [UIUserNotificationSettings settingsForTypes:types categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
}
else {
NSLog(#"system version < 8.0");
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
}
}
#ifdef __IPHONE_8_0
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
NSLog(#"Registering for remote notification");
[application registerForRemoteNotifications];
}
#endif
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
NSLog(#"did register remote notification with device token");
NSString *newToken = [deviceToken description];
newToken = [newToken stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:#"<>"]];
newToken = [newToken stringByReplacingOccurrencesOfString:#" " withString:#""];
NSLog(#"Device token: %#",newToken);
DataManager *sharedData = [DataManager sharedInstance];
sharedData.deviceToken = newToken;
[self requestProfileWithDeviceToken:newToken];
}
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
NSLog(#"Failed to get device token, error: %#", error);
[self requestProfileWithDeviceToken:#""];
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
NSLog(#"Receive push notification: %#",userInfo);
[self processPushNotification:userInfo];
}
Any help would be very much appreciated. Cheers.
