Hi all,

I've not Jailbroken for a long time, but I've finally decided I'd like to upgrade my phone's OS to a newer version.

From a quick glance at the forums it looks like I want to be on 4.3.3 I'm currently on 4.1.

Is it possibly to upgrade to 4.3.3 or would I have to go to 4.3.5 and back again?

Thanks,

G

Do you have your SHSH Blobs for 4.3.3 at all? As this is the only way you can go to 4.3.3 as Apple don't sign this version any more.

You would have to go to 4.3.5 now.

I'll be honest I have absolutely no idea what that means.:confused:

All I know is I'm on 4.1 Jailbroken and I would like to be jailbroken again as I hate my phone without sbsettings. But there is an app that I would like to buy called Oremote that needs a newer version than I'm on.

As does Sky Go.

If you don't no what it means chances are you don't have them backed up. You may only be able to go to 4.3.5.

Do you have Cydia on your phone? Open Cydia and see what it says at the top of Cydia. It should have some firmware numbers like 4.0, 4.1, 4.3.5. e.t.c it might not be them ones but it should say some numbers. What are they?

It says SHSH: iOS 4.1,4.2.1,4.2b3

If I can go to 4.2.1 that might let me use Sky Go, but oremote needs 4.3+

Your SHSH tells me you don't have 4.3.3 SHSH Blobs saved, which means you can only go to firmware 4.1, 4.2.1, 4.2b3 and 4.3.5.

Do you really need a jailbreak? 4.3.5 can be used with a tethered jailbreak, which means every time you reset your phone you have to connect it to the computer and use redsn0w to boot in tethered mode until an untether is released.

The main reason I use it is for sbsettings, activator, infini folders, 5 icon dock etc etc. Lots of things that should have been included in the first place but weren't. I would really miss them all though.

To the extent that I'm wondering if I should wait for 4.3.5 to be jailbroken properly.

Has anything like this been added to the new version?

Also these blob things? Can you download them?

I don't think I could put up with my phone without activator or sbsettings. Just simple things like being able to set the up down volume buttons to change tracks and pause/play so that I don't have to use the rubbish apple headphones is a HUGE reason to JB for me.

Thanks,

G

If that is the case I will have to stick with 4.1 till I get an iPhone 5 or till a new jailbreak comes out. My own fault for not updating in so long.
 
This definitely doesn't work.

How can I go back to my old 4.1? lol Preferably with all my old settings etc.

I packed it up before I startd and I can see the backup in the prefences in itunes but have no clue how to go back.

I'm currently on 4.3.5 with everything restored, but not jail broken. So no sbsettings or infinifolders etc...so it's copied all the apps to screens instead of folders.

I would much prefer to go back to how it was before I started though lol

oh dear. It looked genuine to me but oh well this is the Internet.

What you need to do now is edit your host file to point to the Cydia servers. Download iPhone 4 GSM 4.3.3 firmware and apply it. If you error out and can't get passed the errors you may need to make custom 4.3.3 firmware.

I've tried all of that :( even the custom firmware I made with Snowbreeze wouldn't load up.

I had to get to 4.3.5 just to unbrick my phone.

I think it is completely impossible to go to a version which your phone doesn't have the blobs for.

not if you read thread he asks for help its given its ignored....

you do it in steps... 4.0.1 to 4.3.3 not 4.3.5 back down....


its other who read the thread im trying to help not make same mistake
Click to expand...

I had no way to get to 4.3.3 no blobs.

Can't figure out how to get 4.2.1 even with the blobs tho :(

Tried what Mr Bell said but it says the ipsw is invalid when I try to do the custom signed rom.
 
Back on 4.1 now, but I've got to re-install all the important things like activator :(

Had hoped it would have been backed up but no such luck. It kept all my bookmarks and tomtom favourites etc, but nothing that came from Cydia like emulators etc etc.
 
I really appreciate the advice, but I did try all of that first, the problem is that my 4.2.1 download is not working to restore. I tried without custom ipsw. I couldn't try with one because it said that the ipsw wasn't valid.

Mayebe try another download of the file !


And I've never had the problem it's normal straight forward

I should have said.... I have downloaded it 4 times from 4 separate locations to two completely different PCs both with the same results :(

I was reading somewhere that you can only do it with the beta version of 4.2.1 but don't know if there is any truth in that or how I could get hold of it anyways.

The main thing I wanted to achieve was to get an app working to search for tracks on the built in spotify on my AV receiver. I have subsequently found a different app that is working fine :)

Any more progression with this or did you give up?

I've kind of given up for now, it was a ballache to set it all back up as I like it again and I'm not in a massive rush to go through that again especially as iPhone 5 is imminent.

Really appreciate everyone's help and advice though :)
