Really, all you need to know here is, on the main iPhone screen in iTunes, hold ctrl+alt then click restore.

This gives you the chance to select the psw that you want to restore from.

Key things to remember to do before you restore:

All these are under the context menu you receive from right clicking your phone name in the devices tree in iTunes.

Transfer your purchases

Sync your phone

Backup your phone

Theres few programs that do this, some install spyware, other you have to pay for.. Here is how to do it for free, and without having to install anything.

Download the latest version of DMG2IMG from here:

http://vu1tur.eu.org/tools/

Extract the downloaded zip file.

C# Removing or deleting an element and its contents from xml using regex

I was performaing a code review the other day where i cam upon this code

doc = rover.data.ArtisteDataHelper.getCurrentEventShows(festivalId);
XmlNodeList list = null;
list = doc.DocumentElement.GetElementsByTagName("biography");
while (list.Count > 0) {
      list[0].ParentNode.RemoveChild(list[0]);
}

list = doc.DocumentElement.GetElementsByTagName("description");

while (list.Count > 0) {
     list[0].ParentNode.RemoveChild(list[0]);
}

this operation was being performed over a 7mb file, and took around 18 seconds to complete. So, I thought I would see how fast it can remove these nodes using regular expressions.

I came up with the following code. It was designed specifically to remove elements with cdata inside them, but you can write regex to do anything you want of course, the performance gains will still be the same.

string xmlstring = doc.InnerXml.ToString();
string xmlstringresult = Regex.Replace(xmlstring, @"<description><!\[CDATA\[((?:[^]]|\](?!\]>))*)\]\]></description>", "");
string xmlstringresult2 = Regex.Replace(xmlstringresult, @"<biography><!\[CDATA\[((?:[^]]|\](?!\]>))*)\]\]></biography>", "");
result = new XmlDocument();
result.LoadXml(xmlstringresult2);

Result:
WHILE LOOP: 18 seconds
REGEX: 0.41 seconds

Kindle Fire Cannot load volume misc

Hi,

I had a friend that bricked his kindle fire, so I installed CM7 on it today, while doing so I got this error

E: Cannot load volume \misc!

you might also see

md5 file not found

how do you fix this?

you dont, these errors are ok, just reboot the device after CM7 (update.zip) has installed,

even if you see the errors, when it reboots, it should load fine.

Hope that helped,
