Are
you still using iPhone 4?
The iPhone 4 has already been discontinued from the iOS update, but surprisingly it's also the last iPhone to be able to untethered jailbreak with the latest version. The checkra1n string jailbreak by checkm8 is very useful now, but until 10 years ago, the iPhone 4 is quite useful as a device that can always perform the string jailbreak by using the powerful Bootroom exploit called "limera1n exploit". did.
This time, I will introduce a tool that can unconditionally complete downgrade or jailbreak iPhone 4 to iOS 5.1.1 There are no prerequisites.
In
this method we use
What
is Pluvia?
Pluvia
is the scrip develop for untethered downgrade iPhone 4 without SHSH blobs from apple sever!
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
Before process please download iPhone3,1_5.1.1_9B206_Restore.ipsw
1)
Creating the patched IPSW
Run
./make_ipsw.sh <Input_IPSW> jailbreak (if you want to jailbreak)
Or
run ./make_ipsw.sh <Input_IPSW> (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

iOS!
Getting

We
use cherryflowerJB

after applying this exploit, there is a work to do before restoring normally.
Go to'remove_for_i4' on
the terminal and connect your iPhone 4 in DFU Mode
