Untethered Bypass Hello Screen iOS 12.x – 18.x no Signal (no need change SN)

Apple iPhones are known for their security and protection, especially through the iCloud system. But many users face a common issue — getting stuck on the Hello Screen after restoring or updating their devices. In this situation, the iPhone asks for the previous Apple ID and password, and if you don’t have them, the device becomes locked.

This lock is part of iCloud Activation Lock. Normally, this lock prevents unauthorized access. But sometimes, people buy used iPhones that are still locked to the previous owner’s iCloud. If the original owner is not available, bypassing becomes the only way to use the device again.

What is Hello Screen on iPhones?


When you reset or restore your iPhone, the device shows a "Hello" screen in different languages. This is the setup screen. If the iPhone is linked to an iCloud account, it will ask for the original Apple ID login. You can’t go forward without entering this information.

So, Hello Screen Lock is the first sign that the iPhone is iCloud locked. It blocks access to the home screen, apps, or settings.

What is Untethered Bypass?


There are two types of bypass methods:

1. Tethered Bypass: Works only until the phone is rebooted. Once you restart, the bypass is gone. You need a computer every time to bypass again.

2. Untethered Bypass: Permanent bypass. Even after reboot, the device stays unlocked and usable. No need to connect to a PC again.

In this article, we are discussing Untethered Bypass, which is better and more stable than tethered bypass.

What is the No Signal Problem?


Sometimes, after bypassing an iPhone, the device gets "No Service" or "No Signal". This means the SIM card is not working, and you can’t make calls or use mobile data.

This happens because:

  • The device is not activated correctly with Apple.
  • The baseband or modem firmware is corrupted.
  • The serial number (SN) was changed to fake values.
  • The bypass method blocks network functions.

So solving the No Signal issue is very important if you want a fully working iPhone.

What is Serial Number (SN) and Why Change It?


Many bypass tools in the past changed the serial number (SN) of the iPhone to fake or modified values. They do this to skip Apple’s activation check. But changing SN can:

  • Cause errors during updates or restores.
  • Disable mobile signals permanently.
  • Make the device unstable.

Now, the good news is — with new tools and methods, we can bypass the Hello Screen without changing SN. This means the phone will stay original, and the Signal will work properly.

Basically, it supports a wide range of iOS versions, even the latest updates. Make sure the device is compatible with Checkra1n or Palera1n jailbreak, which is needed for the bypass.
