Steps for Upgrading to and Jailbreaking 4.1

[RodChester]

Hey there folks I just wanted to post my plans for upgrading my phone to 4.1 and then jailbreaking it to make sure everything I do is going to work out ok. Right now I have iOS v4.0.1 that was jailbroken with jailbreakme.com.

First I plan to get PkgBackup from Cydia and backup all my apps this way.
Next I will have iTunes do a backup of my phone.
Then I plan to restore my phone as new and upgrade to 4.1.
I will then run the greenpois0n jailbreak.
Then run PkgBackup to get my apps restored.
Then I will restore my phone from the backup I just made in iTunes to get all my contact info restored.

Does this sound like the right things to do? I am confident that PkgBackup will work and do what I want. My main concern is making sure I get all my contact info back after upgrading. Is it possible to just upgrade my phone to 4.1 without restoring it as a new phone and keep all my contact info that way?

Any help and advice will be much appreciated.

you can save your contacts in Outlook or Windows Address Book and save them that way. you can do this is iTunes under the info tab after your phone is plugged in.

After a OS restore it will ask you if you want to restore from backup or as new so so you don't have to setup a new then restore from backup. The pkgbackup is store in your restore so you will have to restore from backup then run pkgbackup.

Ok so it looks like I need to run PkgBackup, backup my phone in iTunes, upgrade to 4.1, run greenpois0n, restore phone from the iTunes backup and then restore from PkgBackup.

Well I would restore to 4.1 not update/upgrade. They are two different processes. The only other thing you need to consider is if you want to preserve your baseband if your on an iPhone 4.

Lol you just doing to have to do it to see. Restoring the OS and restoring from a backup are done in the same process. As soon as itunes is done restoring the OS it will detect the phone and ask if you want to setup as new or restore from back. This is what it will look like.

 

[RodChester]

Ok I think I have it. Thanks for all the help. I just want to make sure that I do not lose any of my contacts. That is my main concern.

That is stored in your backup so as long as you have that you will be fine.

You might want to keep your baseband just in case the unlock for the new one doesn't come through and you want to sell it later, follow this guide it's great, IF you can't get it to upgrade with the IPSW they tell you to download just upgrade normally with iTunes and it will also work and keep your baseband (I did that and it worked but remember you have to try first with the IPSW they tell you to download)

Why the quote of my post for that? Like me he seems to have no need for an unlock per his post..

Ok so I restore to 4.1 then run greenpois0n then restore my backup in iTunes. I am not concerned with my baseband since I am on AT&T and will be staying there.

Does the restore take a bit to complete. iTunes is showing about 98% complete on its progress bar and my phone is showing about 60% complete on its progress bar. They both have been at this same spot for over 10 minutes. Do I need to disconnect and put my phone in DFU mode and do a restore that way?

 

[TMar]

Did you ever edit your host file for doing downgrades?

No I have never needed to downgrade. I just did the first update to 4.0.1 awhile ago and then jailbroke with jailbreakme.com. Other than that I haven't done anything to change the firmware.

 

[TMar]

And it's till hung at the same spot? And you don't have TU open and running? Sounds like it should be as the BB part. I personally would try to unplug and plug it back in.

 

[RodChester]

Well I unplugged it and it shows the connect to iTunes picture, but when I plug it back in nothing happens in either iTunes or on the phone.

Hey Rod how did it all go, thats what i have planned for this evening.

 

[TMar]

Well I unplugged it and it shows the connect to iTunes picture, but when I plug it back in nothing happens in either iTunes or on the phone.

Try kicking it our of recovery via TU.

Those two bars will not show the same status, don't expect them to. I hope you didn't unplug because of that. I believe the phone is showing a more overall progress while your iTunes is showing progress for the current process. Be a little more patient next time!

 

[RodChester]

Well I restarted iTunes and started the restore over again and it froze at the same spot.

Sorry TMar but I do not know what you mean by TU.

Well it was at that same position for about 30 minutes before I unplugged it and started over.

TU

 

[RodChester]

Ok I finally got error 1004 and then used TU to kick it out of recovery mode. Seems to have worked! Now I am restoring from my iTunes backup.

 

[RodChester]

Bah! I ran greenpoisi0n and it said the jailbreak was complete but there is no loader icon on my phone. Man the last jailbreak was so easy.
