How to update iPhone 1.1.1 to 1.1.2 Unlocked (8 simple steps for Mac & PC)

Notes & Warnings
-I don't know why but almost all the other guides I've seen on the net have you restoring all the way down to 1.0.2. That's unnecessary.
-Though I haven't tried it, the same procedure will also work for 1.0.2 phones. You may need to revirginise first.
-Look here for 1.0.2 revirginizing.
-This will not work on OOTB iPhones with the new 4.6 bootloader. (OOTB at the moment are 1.1.2s. Rumour has it that some new 1.1.1s are coming with the new bootloader too.)
-Don't be afraid to try. Even if you missed a step, you'll just have to start over. There's almost no chance of bricking the iPhone.
-Having said that, here are 3 warnings:
- 1. Do this at your own risk.
- 2. For those still on 1.0.2. If your iPhone has been unlocked previously with AnySIM 1.0, it must be virginised first.
- 3. Do not run AnySIM 1.2.1u in 1.1.2.

Requirements
My starting point was a virginised, activated, jailbroken, unlocked 1.1.1 iPhone. (which most of us have)
You'll also need a WiFi connection for the iPhone.

Software required (Mac)
- iTunes 7.4.2 (for iPhone Restore & Update)
- iNdependence 1.2.5 (PC users will need iPhuc or iBrckr instead of iNdependence, they are only used to kick the iPhone out of DFU mode)
- If you're using iTunes 7.5, you'll need iNdependence_v1.3_beta2 & MobileDevice_7_4_2.framework.zip
Download iNdependence_v1.3_beta2.zip
Download MobileDevice_7_4_2.framework.zip
- FuGu (Mac sftp, scp client for copying files to the iPhone) Download Fugu-1.2.0-English.rar
- WinSCP for Windows

Files Required (links to come)
- Apple iPhone Firmware 1.1.1
iPhone1_1_1.1.1_3A109a_Restore.part1.rar
iPhone1_1_1.1.1_3A109a_Restore.part2.rar
- Apple iPhone Firmware 1.1.2
iPhone1_1_1.1.2_3B48b_Restore.part1.rar
iPhone1_1_1.1.2_3B48b_Restore.part2.rar
- AnySIM 1.2.1u (for unlocking) Download anySIM1.2.1u-independence125
- 1.1.2 Jailbreak Download 1.1.2-jailbreak-UPDATED.zip
- BSDSubsystem, OpenSSH & Oktoprep via Installer
- pntedit Download pntedit_build_3.zip

Steps *Please note distinction between Restore & Update.
1. Restore* to 1.1.2 using iTunes
Put your iPhone into recovery mode. (Hold Power & Home buttons. When screen goes black, release Power only. While still holding Home, plug in the cable.)
Click Restore.
This will give us 1.1.2 and baseband 04.02.13_G

2. Restore* down to 1.1.1 using iTunes
Put your iPhone into recovery mode (see above) & connect to computer, option-click Restore
Select the iPhone 1.1.1 ipsw file.
It will end with a 1015 error. That's OK.
Quit itunes and open iNdependence. iNdependence will kick the iPhone out of recovery mode.
PC users, use iBrickr
or iPhuc and issue the following commands:
cmd setenv auto-boot true
cmd saveenv
cmd fsboot
This will give us 1.1.1 and retain baseband 04.02.13_G

3. Activate & Jailbreak 1.1.1 using jailbreakme.com
Instructions from http://jailbreakme.com/safari.html
- On the Activation Screen, slide "slide for emergency" to get to the dialer pad.
- Call *#307# & the phone will ring
- Delete *#307#, type in 0 and hit Call again.
- Press Answer, Hold & Decline.
- Go to Contacts and create a new contact. Create 2 urls:
Code:
prefs://1f
http://jailbreakme.com
- Select your WiFi network by prefs://1f.
- Press home and call number 0.
- Answer, Hold & Decline.
- Go to the contact again and touch http://jailbreakme.com
- Install AppSnapp
- This will take a while, be patient & wait till the phone rings. Wait again and the phone should reboot by itself.

This will also install Installer for you.

4. Alternate (replaces steps 4 & 5 below) Unlock 1.1.1 using AnySIM 1.2.1u Thanks to mliberatore.
Add this source to installer: http://rep.frenchiphone.com
Install AnySIM 1.2.1u via Installer. It's in FrenchIphone.com
Set Auto-Lock to Never.
Run AnySIM to unlock the iPhone.
Jump to Step 6

4. Install BSDSubsystem & OpenSSH
Use Installer to install the above 2.

5. Unlock 1.1.1 using AnySIM 1.2.1u
Set Auto-Lock to Never.
Use FuGu or WinSCP to copy AnySIM 1.2.1u to /Applications on the iPhone.
Run AnySIM to unlock the iPhone.

6. Install & run Oktoprep on 1.1.1
Use Installer to install Oktoprep and then run it. It's in Tweaks (1.1.1)

7. Update* to 1.1.2 using iTunes
Connect iPhone to iTunes and do an update. (NOT RESTORE)
This will give us 1.1.2 and baseband 04.02.13_G.
Phone will still be unlocked but it's jailed & not activated.

8. Activate & Jailbreak using 1.1.2 Jailbreak (the .JAR file)
PC users will need Java Runtime.
Run the 1.1.2 Jailbreak on your Mac/PC
On completion it'll reboot twice.
This will give us activated, jailbroken, unlocked 1.1.2 with baseband 04.02.13_G. (ie the latest & the greatest)

9. Fix dialer/SMS crash with pntedit for AppSupport
Basically you'll need to patch AppSupport with pntedit with the following values:
my 60 00 0 1 7
my 60 00 0 1 8
my 60 00 0 2 7

or

Download my patched AppSupport. http://rapidshare.com/files/71092650/AppSupport.my.zip

or

Use Installer.app to install iWorld. It's in Tweaks (1.1.2) It fixes the crashes and uses French rules for callerid matching. (untested by myself)

This will fix the iPhone crashing when you try to dial using the keypad.
Calling from an Address Book entry is OK.

DONE

Bro I think you can try using iWorld which is available under installer app......it stated that it could fix the crashing but I don't know if Malaysia supported. Tried it under 1.1.1 but it stated it needs 1.1.2. (Obviously) Anyway, nice guide. Will try it once I make time.

Raymond, thanks for the heads up on iWorld. I haven't looked at how it works but appsupport has a limit of 32 entries so they couldn't have possible catered for each & every country unless they approached the problem in a different way. Anyway I couldn't find iWorld in Installer.app. Which repository is it from?

Soonwai, the iWorld source is from Conceited Software. It's under Tweaks (1.1.2). It stated that it fixes crash on 1.1.2 when used with foreign SIM cards. When I run iWorld, (under 1.1.1) It stated "Size mismatched, your Appsupport framework not supported" or something like that.

Yeah, AppSupport 1.1.1 is totally different from AppSupport 1.1.2. I don't see iWorld and I have both Conceited Software & Conceited Software Beta repositories. Wierd.

Edit: nvm, just did a refresh and it's there now. Thanks!

Hmmm......weird indeed. iWorld is listed in conceited software webpage. I found it when I check the "Recent Package" in Installer app. I'm using Installer v3.0b8 by the way.

Edit : Oh ok cool!

is the 1.1.2 iphone become softer as compare to 1.1.1?

I would say that would depend on the user. Since everyone is different, it'll be difficult to put a general feel on it.

ibrick also can be use to kick iphone start after downgrade the firmware.

Bro soonwai, any luck trying the iWorld? I hope it would let you edit your Appsupport 1.1.2 natively. It would help a lot.

good work u guys.. look what i found http://www.winandmac.com/mobile/iphone/unl...-via-downgrade/

i know its the downgrade method, but looks quite plausible

Just to double check, do i need to un'unlock the phone using onesim first before i restore to 1.1.2? I've read a howto in modmyifone website that states that you need to run onesim first before restoring to 1.1.2.

@Vassele: Not necessary to run Onesim before the the first 1.1.2 Restore. It wouldn't hurt either if you did so you can if you like. I didn't.

Added on November 21, 2007, 12:43 amHaven't tried it personally but from what I've read, it succeeds in stopping the crashing of Phone & SMS app but it doesn't patch AppSupport for proper number decomposition so CallerID/Address book matching won't work all the time. It's actually patching AppSupport with "my 60" where France used to be.

trying my luck.. panic abit just now during the jailbreak session when my phone just showed the usb to iphone picture.. now its all fine now.. prepping to 1.1.2.

Can you upload the Appsupport? Thanks!

Bro Soonwai, I've upgraded to 1.1.2 and tested iWorld....it does work, it stops crashing on 1.1.2. Haven't tried number matching. Too tired now. Will update soon.

Here you go.

http://rapidshare.com/files/71092650/AppSupport.my.zip

Remember to rename AppSupport.my to AppSupport. The permissions should be correct but please double check and ensure that it has the same permissions as the original AppSupport. Wouldn't hurt to make a backup of the original AppSupport.

How'd the upgrade go?

wow,, damn adventurous.!
so hows ur iphone now bro?

the upgrade went fine actually.. and i tried the iWorld application and it did work. No more crashes when sms or using the number pad.

Thanks for the howto.. it really worked!

I use it together with this Guide coz it has pictures for every step! Woohoo..

Bro, any problem with Maxis unreadable text?

Added on November 21, 2007, 3:00 pmOk an update on those people thinking of using iworld.

HP number matching - OK
Land line number matching - OK
Missed call text from Maxis - OK
*100# menu - OK

Enjoy upgrading!

+1 for the above.. the iWorld simply works.

Anyway, just one question..

can i delete the applications that I have already used.. such as the anySIM and the iWorld? It's filling up my springboard.
