I'm going to attempt this today on a iPhone 3gs that was on 4.2.1 I did a restore all settings and content not knowing what it was.gonna do. So I'm going to download gp_win_rc6.1.zip and hopefully that will fix my slide for emergency call only with usb/iTunes background. Ill repost if it works as stated
I appreciate all the effort you put into writing this post about iClarified - Add Comment . I will post a backlink back to your blog on my website as I think some of my clients might find it interesting.
I want to jailbreak my Iphone4 , firmware 4.1, to the latest 4.3.3. I'ts jailbreaked and full of apps from Cydia.
What do i need to do not to loose all my apps with the firmware upgrade?
Do i need to upgrade the firmware in iTunes and then Jailbreak it or it doesn't need to update first?
Cheers from Portugal :)
Using 3gs on firmware 3.1.3 and Baseband 5.12 (New bootrom) JB by spirit n Unlocked by Ultrasnow.
I wish to upgrade to 4.x os. Can someone please tell me
1)Will i lose all data and apps
2) will I have to upgrade from I tunes then JB it? (Just like a New Restore)
3) Can i Use pwnage tool or some other to upgrade n JB at the same time
4) Which SW to use for JB and Unlock and which os to select 4.0, or 4.1 or 4.2 or 4.3(I will need an Unlock)
5)Will firmware upgrade also change BB version?
Will this work with Verizon iPhone 4 with Modem Firmware 1.0.05 ?
I have the version 4.2.6 (8E200).
itunes would like me to update to 4.2.8, and im not sure if i should b/c im still not sure if i should jailbreak or not.
Will this jailbreak work on an Iphone 3g.... it's not an "S"
If not, can anyone point me in the direction of an untethered jailbreak for a 3g that is currently on 4.2.1
Thanks in advance.
Try using Sn0wbreeze. Really easy to use. A few headers: When it saves the new firmware (it creates a new firmware that you're supposed to restore to and it has Cydia on it), you need to locate it and open iTunes. Hold Shift and click Restore on iTunes. Rest is self explanatory.
Dear Cassio,
At the outset first, Hats off to hardworking developers who makes such things possible ....
Jailbreak works perfectly fine on using Green Poison RC6 but this update process fails to preserve baseband to firmware 1.59 (iOs 4.2) in iphone 4 and updates to 2.10.04 which makes iphone 4 unlockable as of now ....
And also no activation procedure exists to activate or hacktivate apple iphone 4 ....
Would u like to throw light on how to go about from here iphone 4 iOs 4.2 (2.10.04) ?? Wat to do next ??
Shall we Wait for iOS 4.3 to get jailbreak and unlocked or wait for 4.2 (2.10.04) unlock ???
Once again thanx for atleast making jailbreaking successful for iphone 4 iOs 4.2 ...
Guys, I found out the main problem:
When I'm entering DFU mode, this happens:
-hold power for 2 seconds
-turning on
-hold home button for 5 seconds
-completely shuts down
-need restore
Any ideas welcome.
i have also facing this problem i have restored my iphone 3gs on 4.2.1 but my iphone gone in DFU mode and no greenpois0n and no limera1n nothing is working on it. did apple stop restoring 4.2.1 and responding for this firmware anymore
Hello, I need help, I have iphone 3GS running the old 3.0.1 iOS and there is and old 04.26.08 baseband. Could anyone be so kind and tell me what is the safest way to jailbreak and UNLOCK(as my iphone is from USA and I live in other country)? And ofcourse is there an untehered jailbreak?
hihi,
i been trying to jailbreak my iphone 4 (ios 4.2.1) but keep failing using this GreenPoison (RC6)..
may i knw what is the problem for jailbreak on my hp?
I tried this and was able to get into DFU but every time i go through the jailbreaking part it tells me it failed...any help please? running 3g version 4.2.1 (8c148)
Just use sn0wbreeze to make a custom ipsw that will give you an unlock, upgraded baseband and 4.2.1 all in one and jailbroken. has worked for 6 iphones for me and friends so far with a 100% success rate.
