Ok This is how I did it. I have Wifi and my Ipad is JailBroken. This voids your warranty. So Backup everything before jailbreaking it. So you can restore it. There are plenty of guides to jailbreak an Ipad.
Once you have a Jailbroken Ipad, you will see cydia on it. Need to Install OpenSSH and also SBSettings (free) on your ipad. Once these are installed if you have a wifi enabled windows computer, you can proceed.
On you windows computer download and install WinSCP (also free). Make sure Ipad and Windows are on and connected to same network using wifi.
On the Ipad slide your finger across the time the SBSettings dropdown will show up. WIfi and SSH button should be green if red press it so it turns green - on.
Next make sure there is a wi-fi ip address. you will need this.
On your windows machine start winscp.
WinSCP Login screen will show up.
For Host name enter the wi-fi ip address of your Ipad - usually similar to 192.168.0.102
User name usually root, Password usually alpine.
Skip Private key file - leave it empty
File protocol drop down list select SCP. Cick Login.
It will take 1-2 minutes. says searching for Host. Asks do you want connect. Click Yes.
You are connected to your Ipad.
On the right side panel click the drop down list select root folder.
double click these folders one by one. Var then mobile then Library then Preferences. In this folder search for com.apple.springboard.plist
Select it and delete it.
Now Poweroff and Restart your Ipad. Close WinSCP. It will ask do you want to terminate session. Click Yes.
When your Ipad restarts Restrictions will be disabled. However whatever restrictions you had will still be in effect. So just Enable restrictions type a simple code you can remember.
Make the necessary changes then disable restrictions.
This 100% works. Will not affect the data on your ipad but it may change some apps to default settings.
I also recommend keeping SSH off on your ipad or removing OpenSSH from Cydia. Just because if SSH is on someone on the same wi-fi network could hack in to it.
Please use at your own risk deleting the wrong file could really mess up your Ipad. The Apple store won't help with a jailbroken Ipad.
