Jailbreak iPhone 4, 3GS iOS 4.2.1 Untethered with GreenPois0n RC5

In this guide, we’re going to jailbreak iPhone 4, 3G iOS 4.2.1 untethered with Greenpois0n RC5. Greenpois0n RC5 can jailbreak iPhone 4, iPhone 3GS untethered running iOS 4.2.1 firmware. Greenpois0n untethered jailbreak does NOT require SHSH blobs for iOS 4.2b3.

IMPORTANT

  • Greenpois0n recommends a clean iOS 4.2.1 restore. If you depend on unlock, do NOT update to iOS 4.1 or iOS 4.2.1 because UltraSn0w doesn’t support new basebands yet. However, iPhone 4 users can update to iOS 4.2.1 while preserving baseband with Tinyumbrella. iPhone 4 users (NOT 3GS or 3G):
    How to: update iPhone 4 to iOS 4.2.1 + Preserve Baseband 01.59.00
  • Tethered 4.2.1 redsn0w Jailbreakers can just run greeenpois0n over it for untethered jailbreak (restore only if you have problem).
  • If you’ve RedSn0w Jailbreak Monte, please restore iOS 4.2.1 first.
  • Greenpois0n can jailbreak iOS 4.2.1 iDevices out of the box.
  • Greenpois0n RC 5 supports iPhone 4, 3GS (any bootrom), iPod Touch 4G, 3G, 2G (any bootrom) and iPad

How to Jailbreak iPhone 4, 3GS iOS 4.2.1 Untethered with GreenPois0n RC5

I think there is something wrong. Procedure you’ve explained doesn’t work for me (iPod touch 4th gen).
If I’m going to Jbreak my iPod it crashes and this is the 2nd time i restore it.. there seems to be some problem i think..

Guess February 10, 2011, 10:28 pm

Why are you in iPhone4 section?

pospam February 4, 2011, 8:35 pm

I have a carrier free iphone4 (unlocked bought directly from apple) with 4.2.1. Is it safe to jailbeak using greenpois0n?

Gallifrey February 6, 2011, 5:21 pm

i think not .. nobody say about bb 06.15 on 3GS,
BTW, if any try it, please share info to community!!!
:-D

hdss February 7, 2011, 6:18 am

Greenpois0n does work on the iphone 3gs with bb 06.15.00.
It took less than 3 minutes, now I don’t have to reboot the phone every time it out of power.
Thanks Greenpois0n

Jflaire21 February 8, 2011, 9:58 am

Yes you can jailbreak it coz i did mine 4.2.1 with a bb 6.15 first you need to jailbroke your iphone with redsn0w then use greenpois0n for untethered jailbreak then your done!

playah February 9, 2011, 5:16 pm

Jflaire21

Could you please provide me with a step by step of how you managed to use GP RC5 on 3gs 4.2.1 baseband 06.15.00 jilbroken with redsnow??

also did you manage to unlock it after Jilbreak with GP?
Thanks

Jack February 4, 2011, 10:08 pm

i have jailbreaks my iphone 3Gs but i am stuck on emergency mode.

i had updated from 3.1.3 to 4.2.1 through apple…

any help … i think i got stuck now :(

shunun February 5, 2011, 10:02 am

me too..Can somebody PLEASE correct me if I’m wrong, but I don’t think there is anyway for us with Iphone 3GS 4.2.1 (Jailbroken with the ipad baseband 06.15.00) to have a Untethered jailbreak and unlocked iphone. I have been searching high and low for this. My phone is unlocked and jailbroken, but I have to boot tethered through redsn0w every time I want to boot it. AND IT IS F**KING ANNOYING. Hope there is a fix soon.
Thanks all.

cabaluser February 7, 2011, 5:45 am

that’s one of the warning of upgrading to 6.15 baseband =)

You put yourself in the risk when you upgraded to it..

Thesaipankid February 8, 2011, 8:31 am

I have the same problem. All I found in YouTube is how to use greenpois0n RC5 but nothing about iPhone 3GS 4.2.1 on baseband 6.15.00. All I want to know is can greenpois0n RC5 work and my iPhone will stay unlock and untethered?

molen77 February 17, 2011, 2:45 pm

after restore to 4.2.1 jailbreak with redsn0w_win_0.9.5b5-5 & continued with GP RC5, install cydia through loAder,
you will got untethered iphone 4.2.1 n unlockable
goodlock

Semsem February 25, 2011, 3:45 pm

I have a 3gs with ios 4.2.1 and 06.15bb I first jailbroke it with redsn0w 0.9.6b5, then jailbroke it with greenpois0n, then unlocked it with ultrasn0w 1.2 from Cydia. It worked perfectly!!

Also if anyone having issues with a blank cydia and a crashing safari, this can be solved by jailbreaking with redsn0w 0.9.6b5 followed by a greenpois0n jailbreak. This also gives you an untethered jailbreak. Good Luck!!

pospam March 26, 2011, 1:00 am

Hi Semsem Or anyone:
I also have 3gs with ios 4.2.1 and 06.15bb I first jailbroke it with redsn0w 0.9.6b5 as you did but then I unlocked using ultrasn0w 1.2 from Cydia (The phone is then jailbroken but tethered). Can I now jailbrake it with greenpois0n and make it untethered?
Thanks for your help.
P.

Paul February 4, 2011, 10:19 pm

Done this, but Cydia is not shown in the Loader window! Is this because the servers are so busy or did something go wrong?
I’ve iPhone 4, running 4.2.1 fresh install (Not worried about unlock) and running Mac osx 10.6.6 Snow Leopard.
HELP PLEASE!

Jenkei February 5, 2011, 12:58 am

Paul don’t worry the servers are down beacuse too many jbreakers are trying to get cydia wait some hours and see the greenpois0n site if it is up then cydia will show up in loader

Jflaire21 February 8, 2011, 10:01 am

You dont need that loader all you need to do is get the cydia in redsn0w if it doesn’t show after you jailbroke your iDevice with greenpois0n. :D

Akaung February 12, 2011, 8:05 am

how? i need to go from iphone(saferi)?or From PC?

uvfreak February 4, 2011, 11:13 pm

Quirin February 5, 2011, 2:22 am

Roymam2 February 5, 2011, 10:49 am

The Loader is Installed but after it opens and gives the “loading resources” message a blank window appears and stays at that. Hoping someone would clarify this issue. Thanks.

SYT February 5, 2011, 10:58 am

Good job greenpois0n. Thanks so much. Hope to release jb for window soon.

strawberryoink February 5, 2011, 11:57 am

thanks greenpoison. cant wait for the windows version! :)

dsinc February 6, 2011, 3:51 am

Greenposi0n failed! They really did not test it before they released. I had successfully jailbreak and unlock my iphone 4 with FW 4.2.1 Baseband 01.59.00. However, the GPS is not working.

iPhoneHeat February 6, 2011, 2:53 pm

error?

dsinc February 7, 2011, 9:03 am

yes! i could not transfer GPS apps from Itunes to iPhone 4, but i could download the GPS from Installous. This will take much time to completed the downloading.

sowat99 February 7, 2011, 5:39 am

Oh my! Good thing I didnt even updated my Ultrasn0w unlock with their present release.. I decided to keep my ultrasn0w which was only supporting 1.59.00 not with the 6.15 support.. guess that update is buggy..

Romario February 6, 2011, 8:46 am

Hi,

Windows version just out in GP website , try to Jailbreak Ipad 4.2.1

Follow the instruction.

After jailbreak running got error
“================================================= ====
Unable to find fs_mount
Unable to find fs_unmount
Unable to find fs_load_file
Greenpois0n initialized”

Just waiting… and finally continue with the process.

Finally Jailbreak DONE like a charm….

Cihuiiiiiii………..

Big Thanks to GP

Mouri February 6, 2011, 2:02 pm

Can I use this Jailbreak with iPhone 3GS new boot ROM? It is currently has tethered jailbreak and it is unlocked using Ultrasn0w. However, the baseband is 06.15.00. Any advice?

pospam February 12, 2011, 3:36 am

I have the exact same question. Please help

whiteghost February 6, 2011, 8:56 pm

toptech February 7, 2011, 7:46 am

I can’t jailbreak my 3GS Iphone with greenpois0n (windows version, I didn’t test with MAC because I don’t have any Macbook). It looks ok almost steps, except for the final step: “can not mount the filesystem” (after some change in file system) and my iphone is stuck in this line. Therefore, I have to reset it.

Can anybody help me? Thank you.

Irvin February 7, 2011, 5:54 pm

For the love of god! give us a guide for updating from 3GS FW4.1 with 6.15 baseband to FW4.2

Not all of us update to 4.2 because of the tethered jailbreak, but almost all of us unlocked it with the 6.15 baseband.

zoki February 8, 2011, 6:36 pm

help 06.15.00

Matt16L February 8, 2011, 5:03 am

This is the best jailbreak out there for 4.2.1. It is the only one that works with the iPod touch 2nd gen mc model (that is what I have). It worked great, took some time though.

sweetjhawk8 February 19, 2011, 7:58 am

hey, how did you get yours to work? I can get to the end but it doesnt say its jailbroken but when I restart my ipod it shows the apple and then the skull. any suggestions would be great!

Thanks

aulac February 8, 2011, 11:39 am

sucessfully jailbreak with 3gs, firmware 4.2.1 base 6.15 after tethering with redsnow for awhile..thank you so much for this.

Goran051 February 8, 2011, 7:17 pm

Works like a charm. Tethered 4.2.1 become untethered in 30 seconds. Everything on device (iPhone 4) stayed untouched. Cydia as well. Didn’t check if all applications works as expected but will report if not.

qwertio February 8, 2011, 8:54 pm

greenpois0n requires internet to jailbreak(since it downloads payloads). One common reason why the jailbraking process always fails is the use of a proxy server to filter your internet connection, which is common in universities. You have to change your network connection(connect to someother wifi, go to a net caf,..) to succesfully jailbreak. But there is an offline solution, which did not work for me, but will probably do for others in this page:

http://jailbreakqa.com/questions/3922/confirmedsolved-gp-rc5-needs-internet-connection-to-jailbreak-if-it-keeps-failing-you-can-manually-place-payload-files-in-folder-and-it-will-work

Although i did not get it to work. I think the payloads should come from a succesful jailbreak, not from the iOS.

louis February 9, 2011, 1:34 am

just Untethered 3GS iphone iOS 4.2.1 real easy everything stayed the same cydia and all apps work

rahulbelekar February 9, 2011, 3:51 pm

sir,
a straight forward question.
i have a jailbroken iphone 3GS fr:4.0.1(8A306), bb:05.13.04, i had a query if i could get the new firmware and baseband and jailbreak my iphone again on the new one; the problem is that i depend on a unlock so should i update or wait for ultrasn0w to get updated for the new bb.

LOL4iphone February 9, 2011, 5:07 pm

Worked perfectly on my iphone 3gs new bootroom, had to do a full restore since it hanged up on me on reset, but its ok. i need to clear up space anyway. xD

wid February 10, 2011, 1:14 pm

sweetjhawk8 February 19, 2011, 7:56 am

did you ever get yours to work? I’m running into the same problem.

Dipro February 12, 2011, 6:20 pm

I was able to Jailbreak my iPhone 4 , 4.2.1 with GP without any hassles…. all works, EXCEPT that I can’t RECEIVE text messages ? All very odd – WhatsApp works, etc, and I can send text messages as normal, but I can’t RECEIVE text messages…. any ideas ?

Dipro February 16, 2011, 6:02 pm

SOLUTION: Simply go to Settings….. then General…. then Network…. then Disable “Mobile Data” and Disable “Enable 3G”….. then re-enable both “Mobile Data” and “Enable 3G” and my iPhone suddenly received all waiting texts and has been working perfectly ever since !!! :))

britt February 14, 2011, 1:21 am

I have a 2G ipod touch that I’m trying to jailbreak. I’m not having any luck with it. I’ve downloaded greeonpoision rc5 and went all through the steps at the end it never says its broken. When I turn the itouch off and turn it back on the apple changes in to a skull and you would think it would be completed. Any suggestions? What do I need to do to fix this? I’ve also tried redsnow with no success because I’m unable to find my IPSW. Please help!!
Thanks

satya February 23, 2011, 12:25 am

Hi!, I have got iphone 4, i have succesfully restored the firmware 4.2.1 and also ran greepoison to jailbreak it. But when my phone restarts after jailbreak, it is showing Itune + wire coming from down instead of main screen. Have tried jailbreaking twice thrice. Can anybody suggest what to do next??
thanks for help

wickedtone March 26, 2011, 3:37 am

I would just restore the phone again and start over or keep looking for a way.

ssrini20 February 25, 2011, 10:57 am

Hello,

I tried to jailbreak my iphone 3gs with greenpoison Rc5, but it said that jailbreak failed both the times on windows.

This is my iphone spec:

Iphone 3gs
new boorom
modem firmware: 05.15.04
ios v 4.2.1

I read through the comments, but I did not find anyone with my config and I am slightly confused with the jailbreak process. Do I need to upgrade my modem firmwire before jailbreaking my phone? I would like to jailbreak as well as unlock the phone.

Please guide me, any help will be appreciated.

Thanks,
ssrini20

amm634 March 1, 2011, 10:23 am

Atlass March 2, 2011, 12:49 am

Have a 3GS, 05.15.04, and the damn program (GP) wont recognize when the phone is in DFU mode. Just sits there waiting and waiting….

Are you retarded? That just goes to show how much time you put into jailbreaking it. Really unlimited itunes money? Are you serious?

Mario April 13, 2011, 6:10 am

Well it’s not impossible my stepbrother jailbroke his and he got free games that cost money. I’m not sure how. I would say but my iPod is being gay and I don’t know how to jailbreak it so yeah you actually can get free iTunes money to download free apps music videos and movies.

Anonomys June 20, 2011, 12:30 am

Hey no need to swear / panic… it might just be stuck in DFU mode. Press the home and sleep button together for about 1o sec, or until the apple symbol appears. It’s that easy!

It honestly took me 2min to figure that out!! LOL

FTI the ipod touch 5 is just a refreshed model of the 4th one, only adding a white model. Plus, it comes with ios 5 so you’ll have to use redsnow 0.9.10b4 to jailbreak it; just make sure your on 5.0.1

Wadup, Im making attempts to do a untethered jailbreak to my iPod Touch 4.2.1 2g and running into an issue…

Ran Greenpoison RC5 for windows (cool), put iPhone into DFU mode (cool), hit jailbreak and it shows jailbreaking on my pc and iPod screen shows running GreenPoison… BUT while this process is running my internet always goes down and process doesn’t finish??? WHY DOES MY INTERNET GET KICKED OFF WHILE AT THIS PROCESS IS RUNNING? Cause I know if it stays on the process will continue????

P.S. I also had untethered jailbreaked this iPod before but restored it once cause I was gonna give it away, question is I tried to restore the backup I saved before restoring it but it didn’t bring it back to the jailbroking state? Little guidance por favor ppl’s

Thank, CiscoDown!
