Don't forget the Thanks button if I helped you!
EDIT: My 12 year old brother who does not have an iPhone and who has never used my iPhone before for anything more than making a call has just successfully completed a 1.1.3 to 1.1.2 downgrade and jailbreak using this guide. I did not help him. That's right. Be ashamed.
Having trouble? Check the bottom of the tutorial for FAQs and Answers!
Did you jailbreak 1.1.3, realize it sucked and now you want to come back?! You don't have to virginize! Just downgrade to 1.1.1, jailbreak with wifi, install oktoprep, upgrade to 1.1.2 (your phone will be working now) and jailbreak that! If you want to stay on 1.1.1, you will have to virginize.
A few notes:
- This tutorial was made on
Windows XP...not Vista. The results should be pretty much the same, but Vista is known for being stupid and it may not be exactly the same.
- This tutorial is for iPhones with
bootloader 3.9 (1.1.1 Out of Box or earlier). It
will not work with bootloaders 4.6 and up (1.1.2 Out of Box and later), however your bootloader can now be downgraded. It is a difficult process and includes opening up your iPhone but if you want to go for it, look
here.
- This tutorial is simple enough for
ANYONE. Guaranteed.
- Unless told otherwise, your iPhone should be
plugged into your computer throughout the entire tutorial.
- You need
WIFI!!!
WARNING: It has been discovered that the 1.1.3 backup files created automatically by iTunes
are not compatible with other firmware versions. This means you will probably
lose your data. You will not lose music, videos, podcasts, etc...They will just be re-synced to your iPhone when you get back to 1.1.2.
Files you will need:
-
Firmware 1.1.1 (download
here)
-
Firmware 1.1.2 (download
here)
-
DFU (Download
here)
-
iBrickr 0.91 (download
here)
-
Dev Team 1.1.2 Jailbreak (download
here)
Let's Do It!
1. To start off, you should be on
1.1.3 and you must have the
3.9 bootloader. Open up
iTunes and make sure you have the latest version
(iTunes 7.6). To do this, click on
Help > Check for Updates. If you do not have the latest version of iTunes installed, it is recommended you do so now as this method has not been tested with other versions of iTunes.
2. Make sure
“Automatically sync when this iPhone is connected” is not checked. This will ensure that your iPhone is not
accidentally backed up during the process and your latest restore point is lost.
3. Click
Restore and a dialog showing “Cancel”, “Backup”, and “Don’t Backup” will appear. Click
“Backup” and when prompted, click “Restore”. This step is
optional but ensures that your settings, preferences, bookmarks, etc will be backed up.
4. If you have not already done so, go
here and download
DFU to your desktop.
5. Right Click
DFU.zip and hit “Extract Here”.
6. Take the newly extracted DFU folder,
right-click it, and select cut. Then open up
My Computer and navigate to your Local Disk (C
.
Right-click anywhere in this folder and click
paste.
7. When iTunes finishes your restore, it will be showing a
“Set Up Your iPhone” page. Ignore it. Instead, go to the start menu and click
Run. When the Run dialog pops up, type in the following:
Code:
c:/dfu/dfu iBSS.m68ap.RELEASE.dfu
Now hit
OK. This will force your iPhone into
DFU mode (an extremely useful run command if I do say so myself).
8. iTunes will pop up and say
“iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes.” Click
OK. It will pop up again. Hit
OK again. Now
hold down shift and click on
“Restore”. This will pop up an explorer window. Navigate to the 1.1.1 Firmware that you downloaded and select it. Hit
“Open”.
NOTE: Unless you manually renamed your firmware, it will not look the same as the one in the picture. Yours will be named: iPhone1,1_1.1.1_3A109a_Restore.ipsw
9. After your iPhone has restored to 1.1.1 iTunes will give you
error #1015. Click
OK. Now iTunes will give you the
“recovery mode” message. Click
OK. Your iPhone will have a white USB cord at the bottom of the screen with an arrow pointing up to the iTunes logo. Unfortunately if we try to use iBrickr to boot now, it will
fail. We have to
restore again. Don’t worry about DFU mode this time. Simply shift-click on
"Restore" and navigate to your 1.1.1 firmware again. Refer to the pic above for help.
10. You will get the same errors as before after the restore has completed. Minimize iTunes and
open your iBrickr folder. Double-click
ibrickr.exe. iBrickr will open and recognize your iPhone. It will give you two options;
“Boot the phone” and
“Begin downgrade to firmware 1.0.2”. Click
“Boot the phone”. The background of your iPhone screen will turn
red and after a few seconds it will boot up.
Close out of iBrickr.
11. iTunes will give you a lengthy message about not being able to access the iPhone because the
SIM is locked.
Click
OK. Now do the following to access your
iPhone contacts:
Code:
- Slide the emergency slider.
- Dial *#306# and hit call.
- Your iPhone will either briefly flash and go back to the emergency call screen, or it will look like you have an incoming call from the number 0.
- If your iPhone is still at the emergency call screen, backspace everything and dial 0 and hit call. If not, continue to the next step.
- Hit Answer to answer the call from 0.
- Hit hold.
- 0 will still be calling you. Hit Decline.
- You will now be in the phone section of your iPhone.
12. Go to your
Contacts section. Hit the “+” in the top right corner. Type whatever you want for the contact name. Click
“Add new URL”. Type
prefs: and hit save. Click
“Add new URL” again. Type
jailbreakme.com and hit save. Now hit
save in the top right corner of the “New Contact” screen. Click the newly added prefs:. This will shortcut you to the
Settings. Click
Wi-Fi and join your Wi-Fi network. Go back to
Settings. Click General > Auto-Lock.
Turn Auto-Lock to Never. Now hit the home button. You will be back at the
“Activate iPhone” screen.
13. Slide the emergency slider again and type 0 and hit
Call. Again, answer, hold, and decline the call until you are in the Contacts section. Chose the contact you created and click
jailbreakme.com. Scroll to the bottom and hit
“Install AppSnapp”. You will be booted to the
“Activate iPhone” screen again. Let it sit for at least
one minute. If nothing has happened, start this step over. if you iPhone has
restarted, continue on to the next step.
14. Your iPhone will boot up like normal and you will see the
slide to unlock slider instead of the
slide for emergency call slider. Slide to unlock and notice the new
Installer icon on your homescreen. Click it. It will refresh your sources and pop up a “Please Donate” screen. Click Donate Later. Go to the
Sources section. Click
Edit in the top right corner. Click
Add in the top left corner. Type in
http://i.unlock.no/. Allow your sources to refresh again.
15. Go to the
Install section. Scroll down and tap
System. Tap
BSD Subsystem. Hit the Install button in the top right corner and hit the Install button that pops up at the bottom of the screen. Allow it to download and install. Now scroll down to
Unlocking Tools and tap it. Tap
Baseband Downgrader. Tap Install in the top right corner and hit the Install button that pops up at the bottom. A
warning dialog will pop open. Hit
OK since you have
already set Auto Lock to never. Allow the
Baseband Downgrader to downgrade your baseband. When it is finished, it will pop up a “Notice” saying so. Click
OK and the hit the
Home button.
16. Bring up
iTunes and click
OK through any dialogs that it may pop up. You will once again be at the
“Set Up Your iPhone” screen. Put your iPhone into
DFU mode using the
run command as you did earlier.
17. iTunes will pop up and say
“iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes.” Click
OK. It will pop up again. Hit
OK again. Now hold down
shift and click on “Restore”. This will pop up an explorer window. Navigate to the 1.1.1 Firmware that you downloaded and
select it. Hit
“Open”.
NOTE: Unless you manually renamed your firmware, it will not look the same as the one in the picture. Yours will be named: iPhone1,1_1.1.1_3A109a_Restore.ipsw
18. Your iPhone will start up normally and have service! Again, iTunes will be showing the
“Set Up Your iPhone” screen. Ignore it and open
Safari on your iPhone. Navigate to
jailbreakme.com and hit
“Install AppSnapp”. Allow your iPhone to be jailbroken and
soft restart. Click on the new Installer icon. Go to the Install tab and go to
Tweaks (1.1.1). Click on
OktoPrep and install it. After the short installation, click the
Home button.
18.5. IF for some UNGODLY reason, your iPhone does not start up normally... Boot it with iBrickr. Then follow the rest of step 18. Sorry it took me so long to get this step up
.
19. Back in iTunes, make sure you have
“Restore from the backup of:” selected and click
Continue. Allow
iTunes to restore your iPhone from the
backup you made earlier.
20. If you get the message
shown below, you will have to choose a
different backup to restore to or set your iPhone up as a
new phone. This is unfortunate but I believe
1.1.3 backups are
not compatible with other firmwares. It’s always worth a try though.
21. After your iPhone has been restored to the backup,
shift-click on Update. Navigate to your
1.1.2 firmware, select it, and hit
Open. Allow your iPhone to
update to 1.1.2.
NOTE: Unless you manually renamed your firmware, it will not look the same as the one in the picture. Yours will be named: iPhone1,1_1.1.2_3B48b_Restore.ipsw
22. After the update
iTunes will prompt you to
upgrade to 1.1.3. Click
“Don’t Install”.
Exit out of iTunes.
23. 24. Open up the 1.1.2-jailbreak folder you downloaded. Double-click on windows.bat. A command prompt window will pop up followed by a Java interface. Tick “Install SSH” (optional) and hit Jailbreak.
NOTE: If you have problems with this step with anything, go here and get the latest updates for Java.
24. Allow your iPhone to be
jailbroken. This will take around
10 minutes and your progress can be viewed in the
command prompt window. When the jailbreaking process has completed, close out of the command prompt window.
25. You are now
Jailbroken with the phone, SMS, YouTube, etc all fully functional!
Have fun!
FAQs + Answers:
Q. I accidentally upgraded my unlocked phone to 1.1.3... Can I use this to downgrade and re-jailbreak and unlock?
A. Yes you can! However, I am assuming you have the old 3.9 bootloader since you had your iPhone unlocked. With the new bootloaders for 1.1.2 and 1.1.3 Out of Box iPhones, this tutorial will not work.
Q. The DFU deal isn't working for me... is there a way I can do this manually?
A. There sure is! Here are some easy steps:
- Plug your iPhone into the computer so you can hear the "plugged in" and "unplugged" sounds
- Hold down the power and home buttons until you hear the "unplugged" sound
- When you hear the "unplugged" sound, let go of the power button and continue to hold the home button
- Your screen will stay blank but you will hear the "plugged in" sound and iTunes will recognize your iPhone
You are now in DFU mode. Continue with the tutorial.
Q. I'm on a Mac... what do I need to do differently?
A. Use the manual method described above to put your iPhone in DFU mode. Extract files and run them however a Mac does. When told to use iBrickr to boot your iPhone, instead open up the Dev Team 1.1.2 Jailbreak... then click the boot iPhone from restore instead of the Jailbreak button!
Q. I don't know what bootloader I have! HELP!
A. To check your bootloader add this source to your installer:
Code:
http://www.trejan.com/irepo
Install BBInfo under the Utility category. If you have 4.6 or up, you cannot use this method.
