Get Past "Different Sim Detected" message and keep iPhone from Locking Down into Emergency Call Mode
For this procedure You Need:
1. To Be willing to Blank/Lose ALL Data from your iPhone
** You Might Be able to keep your data by restoring from a backup after this procedure... but I am Not Sure
** I didn't try because I'm giving this phone to my girlfriend and I don't want here to see the numbers to my other bitches
2. Get A Blank/Inactive Sim Card from AT&T (T-Moblie might work as well, not sure)
3. A Wifi/Wireless internet connection for your iPhone
4. Redsnow application for JailBreak
5. Firmware file 3.0 "iPhone1,2_3.0_7A341_Restore.ipsw" for Redsnow to operate
!!!!!!!!!! BEGIN PROCEDURE !!!!!!!!!!
Sim Card:
- Get A Blank/Inactive Sim Card
* I went into AT&T and they just gave me one
* Don't let them scan it... that activates it and you need a blank for this procedure *
*** You are Going to Lose Your Ability To Restore Data From Itunes Beyond This Point ***
iTunes Prep:
- Get iTunes to a point where it is setting up a - NEW iPhone when you plug your iphone in
There may be other ways but I went to the extreme to be sure:
- Uninstall iTunes and DELETE ALL ITUNES Data And Backups Including Firmware *.ipsw files
- I believe deleting the itunes installation directory will do
*** You are Going to Lose ALL DATA On Your PHONE Beyond This Line ***
Phone Prep:
- Turn Phone: OFF
- Insert BLANK SIM
- Enter Phone into "FORCED RESTORE Mode" By doing the following:
-- Have iTunes 8.2 Open
-- With the Phone OFF... Hold Down The Home Button and Plug the phone into USB While STILL Holding The Home Button
-- Keep Holding The Home Button until you get a reaction from iTunes
- iTunes will say: it has "located a phone in recovery mode" << or something of that sort
- Proceed with the restore/update to 3.0 when prompted
** DO NOT RESTORE FROM Previous backups that have data **
** I believe the backups contain the SIM Carrier ID which will cause a conflict when you insert a SIM from a different Carrier
** In theory this is why we are getting the "Different SIM detected Message"
Restore Complete:
- When the restore is complete it said something like "Waiting for activation" or "Not activated"... This IS What we want
-- Turn Airplane Mode: ON
-- Turn 3G: OFF
-- Turn WiFI: ON
* This may not be necessary... I just did it as a precaution to keep the phone from reaching a carrier signal and lockdown into emergency call mode
- JailBreak Phone with RedSnow using the 3.0 firmware file: iPhone1,2_3.0_7A341_Restore.ipsw
- Install Cydia during jailbreak
- Install Ultrasnow
-- In cydia add source: repo666.ultrasn0w.com (the 0 in sn0w is a 0-ZERO)
-- Intstall UltraSnow from source or by searching for ultrasnow in cydia search
Ultrasnow Installed
- When ultrasnow is installed:
- Turn Phone OFF
** Don't MIX Up The SIMS or you will have to do this all over again
- Take Blank SIM Out
- Put NEW Carrier SIM IN (such as T-Mobile)
Turn Phone ON
- Turn Airplane Mode: OFF
- Turn 3G: On
* You should see your NEW carrier signal come online =)
* If you do not see your carrier signal come on with a reasnoable amount of time - just reboot once more
** This has worked for me twice on 2 phones.
** The KEY is AVOIDING Activation/Carrier Signal until ultrasnow is installed
