Jay Jones: i downloaded the jailbrake and my modem firmware and when i turn off my phone i open my jailbreak but it doesnt have a place where i can browse and it keep telling me that no device is dectected and also i have the latest update of itunes.. why my jail brake want want work?

huntercat93: Thanks man it works!

AlmightY ClowN: Can you pliz give me a link where i can download Redsn0w

Shaan Khangura: thanks mate. worked perfectly. my phone was getting crazy weird so i just re did this and it works fine now

Mike Robin: After unlock they way you, do you think I can use T- mobile sim card..?
Now its lock with AT&T

leotheangrylion: Hi, I followed your instructions and got as far as installing the firmware on the device and redsn0w said 'Done. The rest of the process takes place on the device'. But on my iphone 3G (with original fw 4.2.1) the screen remains blank (but not entirely black, but dark shade of blue, meaning the screen has power) and nothing else happens. I downloaded iPhone1,2_4.2.1_8C148_Restore.ipsw and using redsn0w_win_0.9.15b3 (as it's the version I found on redsn0w website).
 
Before doing this, the phone was restored to factory setting but since it's locked to AT&T and I'm on T-mobile, iTune said 'the phone could not be activated at this time'. That's why I decided to follow your steps to both unlock and jailbreak the device.

In order to put the phone into DFU mode, I held down the Power and Home button for 10 sec and then released the Power button till it goes into DFU mode. I tried the normal method on the redsn0w but it didn't work.

So, now when I restart the phone, it goes back to the normal mode.

skaterchic73: Thanks You! Your video was very simple and complete. Keep making em. Subscribing now:)

WonderTechnology: @rameshkrish75 Welcome anytime.

WonderTechnology: @2jzsupra100 Welcome and there can be two solutions to this the first one you should try is to reinstall the unlocking software from cydia. If that dosnt work you will need to restore it in order to that i will make a speacial video because it is a little diiferent then usual and you should then rejailbreak/unlock. Be sure you use the correct firmware download
