Now you can update your iPhone 4 to iOS 4.2.1 with preserving 1.59.00 baseband, which means that you will be able to unlock your iPhone 4 with ultrasn0w 1.2. Let's check out the full step by step guide after the jump
i hope those of u with 3g/3gs are enjoying their updated unlocked devices, all props to @MuscleNerd & co. for making this possible :) , hopefully the iphone 4 on 2.10.04 and 3.10.01 follows within a good time table.How can you fix these problems:
on a very important side note, before anyone starts to complain about battery drainage issues after installing the new ultrasn0w on the 6.15.00 updated BB, the culprit here is not ultrasn0w, it's the hacktivation process (activating the phone by pwnage tool or redsn0w rather than using an official carrier sim to do so) that u mostly did while jailbreaking.
The 4.1 and 4.2.1 ipsws unlike their old ancestors, seem to keep looking for valid push certificates all the time, either thru your wifi, or thru your cellular data network (which u only have after installing ultrasn0w and hence u accuse it) , this can be seen clearly if u have a cellular working data plan for 3g or edge and u watched the settings > general > usage > cellular network data (sent & received are continuously increasing even without using any internet traffics on the phone) , this will also render the phone going hot even in stand by mode and also very rapid battery drainage occurs plus consuming ur data if you were not on an unlimited plan.
so to resolve this, u either:
A) 1st Solution: try to activate the phone using the official sim if u have it (even if the sim itself is old and not working) , or borrow it from a friend if it's possible, by any means, try to have an access to one and use it
B) 2nd Solution: if A is not feasible, u can install SBsettings from featured cydia packages and turn wifi and data off when u r not using it (shuts down both 3g and edge) , till C is done
C) 3rd Solution: there is a very nice module being worked on by a trusted jailbreak app dev, namely @sbingner , which ll resolve that issue for those having it, the details of which shouldn't be disclosed until he finishes his awesome work, till then, either use A or B to resolve the issue if it exists for youIn case you're one of those who suffering from the above mentioned problems after unlocking their devices with ultrasn0w 1.2, you have to try the above solutions as they will handle the situation, but don't forget to feed us back with your results on the comments section.
The new redsn0w 0.9.6beta5 is out. It gives both Windows and OSX users the ability to flash the iPad 06.15 baseband on iPhone3G or iPhone3GS. It fetches the baseband files directly from Apple for now (the only IPSW you ever point it at is the stock IPSW for the FW on your iPhone right now). There may be a long delay while it’s doing this (their servers are currently getting pounded).For whom is this Guide:
WARNING — YOU DO THIS AT YOUR OWN RISK! PLEASE UNDERSTAND THE CONSEQUENCES OF UPDATING TO 06.15.
- There is no way to come back down from 06.15, and there’s no hiding the baseband version from Apple. You’ll be voiding your warranty in a very obvious way.
- If some future baseband comes out with a critical fix, you won’t be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn’t update to it if you wanted to keep your unlock anyway).
- Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail). You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).
Faiz: @MuscleNerd btw @sherif_hashim was working on i4 since long ? Did he not find anything interesting.This news gives some hope to iPhone 4 users who stuck on iOS 4.2.1 or iOS 4.1 with upgraded baseband as BB 02.10.04 or BB 03.10.01. More updates as they come! Stay tuned !
MuscleNerd: @mfaizulislam just the opposite :) @sherif_hashim has provided very nice crashes for i4 BB, which we can explore more starting Monday :)
TheBigBoss: It seems that Apple has decided to put a baseband requirement on iOS. So at this point, if you are using Saurik’s server or tiny umbrella and trying to restore 4.2.1 on an iPhone 4, you will end up in recovery mode and tiny umbrella will not be able to pull you out of recovery. In this case, you will have to restore 4.1 again or you will have to restore 4.2.1 stock and be tether jailbroken. (Of course, I recommend 4.1 and not bothering with 4.2.1 at all). If you are an unlocker, this is a no brainier. Do not update to 4.2.1 even to test it at this point.So we highly recommend to stay on iOS 4.1 and wait until the situation became stable, specially who want preserve their unlock. for now you can check iOS 4.2.1 features form here, and its jailbreak guide with redsn0w 0.9.6b4 from here. Stay tuned
By all accounts, we’re within a few days of Apple’s official public release of Firmware 4.2. Here’s what you need to know:Better explanation? iPhone hacker comex could make untethered jailbreak until iOS 4.2 beta 3 (that's why you see it's SHSH in Cydia) and is working on extending it to final iOS 4.2. iPhone 3G and iPhone 3GS will get Ultrasn0w unlock once iOS 4.2 is released while iPhone 4 will get it a bit more but as soon as possible ! So, stay tuned for some good news here !
- Thanks to geohot’s limera1n exploit, and our original pwnage2 exploit, and pod2g’s ipod2g-MC exploit, absolutely all devices at all iOS devices at all
- The untethered jailbreak of the very latest FWs and devices depends on @comex hacks. His hacks so far extend only to 4.1 and 4.2beta3. He’s working on a way to extend it to 4.2 and beyond. Just wait for him to work out his method.
- iPhone 3G and 3GS unlockers will be covered by our upcoming unlock. Stay away from any updates to Apple FW until our official release and you’ll be okay. Just stay away from all Apple IPSWs :)
- iPhone4 unlockers are not left out in the cold. @sherif_hashim has found some very promising avenues to pursue. Those will be explored as soon as possible after all the 4.2 madness.
What does this mean to you?
- If you’re an unlocker, just stay where you are. Please, just stay where you are. Any mistakes you make now may be permanent.
- If you only care about the jailbreak, feel free to experiment but keep in mind that any mistake you make may result in you losing pictures or notes or bookmarks that you’d rather keep. Honestly unless you love living on the bleeding edge, it’s better to just wait for official updates from Cydia/redsn0w/PwnageTool.
- Don’t buy or donate to any unlock or jailbreak scammers. Every legitimate solution you will find for unlocks or jailbreaks will be offered without an extended hand. That’s how this community works. It’s about freedom, not donations.
MuscleNerd: if you’re on 3G or 3GS, just a day or 2 at most after 4.2 is public (just enough time to verify stuff)This reply brings both bad and good news, why? because he didn't mention anything about iPhone 4 baseband 02.10.04, this may indicates that iPhone 4 unlock may be delayed and not released at this time.
This will never be real. Media, understand it. ~geohotSo that, if you see any picture or video claiming the unlock of those basebands by limesn0w, they are completely fake.
since nearly all my received tweets ask about both BB, I can report very early "initial" 1st step success on both sides, calmed down? :)
A new exploitable baseband crash has been found. An unlock will very likely be released after iOS 4.2 and will unlock both BB's of 4.1 & 4.2And now Veeence is mentioning the discovery of new exploitable baseband crash, and confirming again about ETA for the unlock which is very likely be released after iOS 4.2 official release by November, so that it will be able to unlock both basebands of iOS 4.1 and 4.2.
