What is Pluvia?

===============

Pluvia allows you to untethered downgrade your iPhone 4 without SHSH blobs! 

It uses the iOS 7.1.2 iBoot exploit "De Rebus Antiquis" by @xerub and @dora2-iOS.

Beta 1.6 Limitations

====================

Only for Mac!

Only supports iPhone3,1. 

Only supports iOS 5.1.1 (9B206), 6.x, and 7.x.

Can only jailbreak iOS 5.1.1 and 6.1.3

NOTE: 8GB iPhone 4's that shipped with iOS 6 can only run iOS 6 and newer, NOT iOS 4 or 5. This almost certainly can't be fixed.

How to use Pluvia

=================

1) Creating the patched IPSW

Run ./make_ipsw.sh jailbreak (if you want to jailbreak)

Or run ./make_ipsw.sh (if you don't want to jailbreak)

2) Restoring the firmware

Connect your iPhone 4 and put it in DFU mode.

Run ./restore.sh <Patched_IPSW>

Wait for that to complete.

When your phone reboots the Apple logo should blink and then it will boot the older iOS!

Getting out of recovery mode after restoring to stock iOS

=========================================================

Run ./make_ipsw.sh <Any_Supported_Input_IPSW> reset

Connect your iPhone 4 and put it in DFU mode.

Run ./restore.sh <Reset_NVRAM_IPSW>
