Will my stuff lost after downloading ios 7 without UDID?

I have not download it yet cause i scared something might go wrong like not be able to open my iphone 5 or i will lost all of my precious photos in the phone. Can any of you give me a confirm if you had tried this youtube tutorial and whether it work?

I tried another one, which bricked my i phone 5…
be careful…

It's completely unsafe to install iOS 7 without a UDID registration. You need to register your device's UDID with a developer account through a site like http://www.udid.in/.It's $5, and then you don't need to worry about Apple disabling your device for trying to install unreleased software. It's not worth the risk for $5.

  • Will my iPhone become bricked after updating to iOS 7 without registering my UDID? I recently downloaded iOS 7 without registering my UDID number. I have followed the steps perfectly by holding shift and clicking update software on iTunes and selecting the iOS 7 ipsw. I was wondering if my iPhone will become bricked when the iOS 7 beta 2 comes out to developers. I have watched one youtube video and it says it will become bricked and read a comment on another website saying it won't if you have followed the steps perfectly. Will you guys help me?
  • What's next after UDID registration? So, I've a problem. I paid for the UDID registration and now I don't know what's next because I don't know if I have to go somewhere to download something or if I have to wait some days because I checked on iTunes and it says that my iPhone is updated.
  • What do I do after registering my UDID number? I used the website udidregestration.net and I got the confirmation email that it has been registered. I have the iPhone 4 Model A1349, I tried it once and it says that it is not compatible. If anyone can give me a good link to get one of the ios 7 betas (download) it would be much obliged and I will rate you a solid five stars.
  • Just updated my iPhone 4s to the IOS 8 update and lost all my stuff So I have ICLOUD on my iPhone and on my mac, but when I updated my phone it restored everything back to from 2013 (2 years ago) so now I don't have my recent contacts and apps and music on the phone. My macbook pro has my recent messages and contacts but I just don't know how to transfer it all of it onto my phone. Or is their another way to get it all back from 20 min ago before I updated my phone?!
