I think it should work as long as he is not in DFU mode. Then again, I never had this problem before either.

I wonder if he can kick the iPhone from the recovery mode either using TU or iReb. I remembered kicking one of my friend's iPhone using iReb ... who knows, it might work.

i am still new so need some explaination pls..
thank you vr much!

You can always download whatever version of iOS firmware 3.1.2/4.0.1/4.1/4.2.1 etc etc from a lot of places (iClarified and ModMyi is a good reliable source)

BUT it does not mean you can install them into your iPhone. Downgrading your iOS (which is basically what you're trying to do), requires you to have saved (either in Cydia or locally) the SHSH blobs either using Cydia (when you first ran Cydia after your jailbreak and press Make My Life Easier) or locally.

Without these blobs, you're done .... ntohing can be done to install those older firmwares.

Here some a noob question .. I want to ask how to jailbrake ? Got cydia software here ?

Cydia is an application in the iPhone that is installed once you have jailbroken the iPhone. It's not an app you can install like any of the apps from the apple store.

Just follow some of the post where links to guides for jailbreaking has been posted and you will be fine.

I really scare to jailbrake my phone , but if I'd not jailbrake my phone is empty ..

hi is there an unlock already for iphone 4 ios 4.2.1 baseband 03.10.01 pls inform me thank you!!!!!!!!!

Search for Gevey Sim. No software unlock for now.

Yeap, my friend got his refund from cutyoursim today. He's a bit upset because if he had been a day earlier, he would have gotten his phone unlocked.

Shift + Restore
wer to press this!!!

In iTunes, press the shift key on your keyboard and at the same time press the Restore button in iTunes. A window will appear asking you to choose te IPSW file.

is it a must to put it in DFU mode?

To jailbreak your iPhone yes (I'm sure David will not be happy so I will not explain any further as I don't want to get this thread closed).

Let's wait until the JB thread is re-opened tomorrow and I can explain further what you need to do.

Apologies, but I'm respecting the rules of the forum here.

Yeah i really need to know what must do to jailbrake .. Hope anyone here help we

The JB thread is now opened so I will explained further about the DFU mode. There are 2 types of DFU mode, one is the normal DFU mode while another is the limera1n (pwn) DFU mode.

You need to be in the pwned DFU mode to allow for redsn0w to inject the limera1n exploit. Fortunately, redsn0w comes with a great step by step countdown timer for you do put the iPhone in the pwn DFU mode.

Just follow the step and your factory unlocked iPhone should be jailbroken via redsn0w.


For those who have locked set, pwnagetool has been released (for Mac) and this allows you to create a custom firmware which will enable you to preserve your baseband.

i have a 4.0 3gs with baseband 05.13.04
i use snowbreeze to update it and preserve baseband to 4.2.1..
fortunately i have successful restore it without error but unfortunately i am stuck with dfu loop after successfully restore it..

any ideas??

My phone baseband is 04.10.01 .. So ?

Woah shocking news.. How are all the buyers gonna be refunded

My friend told me that he got his refund already. So I guess refunding the money is not a problem.
