So I was trying to unjailbreak because it started messing up with my app store downloads. I went to general and reset all content and data. I am using an iPad Air iOS 9.0.2. Now, my device is stuck in a boot loop. It will not update or the bar won't move. If I try rebooting (holding sleep and home buttons) it just takes me back to the white screen with the apple logo and the bar that never moves. So I try to plug my device to my computer and it's not showing up on iTunes. When I insert the cord to my iPad, the computer makes the connection noise and everything and even opens up iTunes, but I stool can't see my iPad synced. Im really scared that I'll lose my iPad so please help. ;-;
Got a tip for us?

If I'm not mistaken, "erase content and data" is a big no no on JB'd devices. Your only solution now is to put iPad in DFU, restore your iPad as new and update to the current iOS. Obviously you'll lose your jailbreak, but not your iPad.
Steps for DFU mode:
1. Plug your device into your computer with a USB cable.
2. Turn off the device.
3. Hold the Power button for 3 seconds.
4. Hold the Home and Power buttons for 10 seconds.
5. Release the Power button but keep holding the Home button.
After about 15 seconds you will be alerted by iTunes saying that it has detected a device in Recovery Mode.

And…this is why we do not "Erase All Content and Settings" from the device itself when it's jailbroken. 
Typical newbie indeed... I'm so ignorant that I did not know what a DFU was... I know however how to get my iPad Mini 1 in recovery mode and connect to iTunes. However that does NOT do the trick... I have backed up whatever I might need and all I want to is acquire a new virginity, forget about Cydia and get back into Apple's fold... Any further advice would be well appreciated.
Thanks. It's an important detail, because most of the advice you find on the Internet doesn't state the iPad must be in recovery mode before restoring.
There is a difference between DFU Mode and Recovery. Recovery mode still uses the bootloader and will display the connect to iTunes symbol on your screen.
DFU does not use the bootloader and the screen is blank.
Thanks for the clarification... It's easy to get confused, newbie or not.
Actually Cydia Impactor does exactly what you said you can't do...
You know its in beta right? do some searching, see what devices it does and does not work on and the percentage that works or fails and make an informed decision.
With Cydia Impactor, you do not use the Erase All Contents and Settings option from the Settings App.
The problem here is that he did NOT use Cydia Impactor, and can not use it when you are stuck in a boot loop.
A restore from backup in iTunes does nothing to unjailbreak you. It just restores your data.
An upgrade through iTunes while jailbroken will have the effect of leaving behind parts of the current jailbreak. If you ever re-jailbreak later it can result in not being able to remove the untether jailbreak of the past jailbreak (the parts that got left behind) and not being able to install tweaks. The end result of that is a forced restore, which can be a problem if Apple stops signing a jailbreakable version of iOS when you are forced to restore.
You can do a restore and upgrade in iTunes, you don't need to be in DFU mode to do that as it wipes the phone. DFU is not strictly necessary if you have a functional phone, but it's an extra measure I take to protect myself.
A DFU restore is of course necessary if your device is in a bootloop and is unable to boot into Safe Mode.
