    Hey guys, so I'm helping a friend fix her phone. It suddenly turned off and wont turn on. Only a apple logo for 3 seconds and turn off. I can put it into recovery mode and tried reinstalling 3.1.2, which she had before, and it will give me a error which is because of apple not signing those files anymore

    well i researched and found out that she can update to 4.0 and still be able to Unlock the phone.

    My question is that what is the difference between Hacktivated and "unhacktivated" files? i downloaded a custom 4.0 file which is already Hactivated. Im guessing this will allow her to activate her phone even if she doesnt have the sim that the phone is locked to?
    She is on O2 and the phone is locked to Orange. So would it be a good idea to go with the Hactivated file to restore if she doesnt have a Orange SIM?

    Or should i restore using a original 4.0 file and then tell her to get a orange sim so she can activate it?

    After restoring and activating i will use jailbreakme.com to jailbreak and ulrasnow to unlock, is it ok?

    Also her phone was already JB on 3.1.2 and i dont know which method she used to JB before

    Any help would be greatly appreciated

    You can only go to 4.0 or back to 3.1.2 if the SHSH are saved in Cydia/TinyUmbrella.

    Hacktivating = activating the iPhone through the jailbreak program.

    Activating = using an original sim to activate the iPhone.

    So I can't go up to 4.0 from 3.1.2? I thought it was only if you wanted to go back?

    So with a hacktivated file I can activate the phone with any sim and will allow me to jailbreak and unlock? So it will give me access to the phone after I restore it? Sorry kinda noob

    You need the SHSH saved to from firmware to firmware. If you don't have the SHSH saved you'd have to go the newest firmware 4.2.1 or whatever the new firmware is at the time. Apple stops signing the older version of an OS when they release a new one. Preventing iPhone users to restore to the older firmware. That's when the SHSH come in handy.

    The jailbreak whichever you use will hacktivate the iPhone.

    Oh damn. So the only option we have is to upgrade to 4.2.1? I'm assuming that there isn't a jb and more importantly unlock for 4.2.1?

    You can jailbreak and unlock on 4.2.1 but right now it's a little more complex.

    The jailbreak is a tethered version, meaning every time you reboot the the device you need the jailbreak software to turn it back on. An untethered version of the jailbreak should be out soon.

    To unlock, you need to upgrade the baseband to the iPad - 6.15.00

    To read more about the new jailbreak/unlock go to www.blog.iphone-dev.org

    thanks, im helping someone not close to me and im sure she will be very confused, dammit!

    cant i edit the hosts file and put this in 74.208.10.249 gs.apple.com and downgrade? im guessing this requires SHSH as well, man what a bummer

    Editing the host files and following the guide will only work if the SHSH were saved.

    If you want to keep the your baseband = possible unlock, you should always update with a custom firmware file.

    For 3GS, 4.2.1 JB are either untethered (old bootrom) and tethered (new bootrom).

    Thus, with a custom 4.2.1 firmware file, you can update to 4.2.1 either untethered or tethered and still unlock.

    So you're saying if the 3GS has a old bootrom I can jb untethered to 4.2.1 and also unlock it? :eek: that would be great. I have no idea what baseband it is since the phone won't turn on at all. Three seconds of apple logo and then black :(

    Give f0recast a shot to see what baseband is, maybe it can see it but it's a longshot.

    It doesn't really matter if you update and retain the baseband only to find it wasn't an unlockable baseband anyway, you didn't have a chance to start with.

    That would mean the phone has the unlockable 5.13 baseband. You want to keep that. The issue would be if it's a untethered or tethered JB. Is the phone currently stuck in recovery mode?

    The real issue here is he has a dead phone that needs a restore with no shsh saved.

    Updating to 4.2.1 is really the only option from here, just saying do it with the ipsw that wont update the baseband so you have the maximum amount of options available to you.

    All the questions on versions determine what you can do after this is done, that's it. But not doubt this needs to happen. Anyway your going to like 4.2.1, I do. It also sounds like you are set for a current untethered and unlockable but we won't know for sure until the phone is working again. Also if you somehow find those shsh on cydia, you could even go back down to whatever version you have saved.

    Think, serial with K is refub. Don't think it matters at this point whether the phone is old (untethered) or new (tethered) since the phone is in a state where you have to restore to 4.2.1. You best option is to restore with a custom 4.2.1 firmware file (one that keeps the current unlockable baseband).
