Jailbreak iPhone 3GS/3G iOS 4.2.1 and Update to Baseband 06.15.00 with RedSn0w 0.9.6b5
Redsn0w 0.9.6b5 can jailbreak iOS 4.2.1/4.1 and update iPhone 3GS / 3G baseband to 06.15.00 which is unlockable with UltraSn0w 1.2. Those iPhone 3GS/3G users stuck with Baseband 05.15.04 & 05.14.04 need to update baseband to the iPad baseband 06.15.00.
Fortunately, RedSn0w 0.9.6b5 comes with the feature to jailbreak and also update iPhone 3GS/3G baseband to 16.15.00 to unlock with UltraSn0w 1.2. RedSn0w is available for both Windows and Mac OS X. PwnageTool 4.1.3 also does the same thing and prompts if you want to update baseband, however, it supports Mac OS X only.
IMPORTANT: If you do flash your baseband via redsn0w, please keep it plugged into USB the whole time. You don’t want your battery to die during the flash process!
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).
Certainly don’t update to 06.15 if you don’t need to! Only do this if you need the unlock and you’re stuck on 05.14 or 05.15, and you’re willing to assume the above risks.
*** Some users are reporting WiFi, GPS and battery drainage issues after jailbreak and unlock.

I’ve tried restoring it on ITunes but I still keep getting errors 1015 & 3194 when it’s contacting apple.

hai …i too have the same issue..my iphone 3gs stucked on the recovery mod….plz help me ya..
Okay. When you have your phone looping the startup, you should do the next.
1.remove your iTunes and re-install it.
2.Plug your iDevice to computer
3.Then go to DFU mode with HOLDING THE HOME AND POWER BUTTON.
Release POWER BUTTON once you get the cable picture on your screen then wait for the pop-up in your iTunes and release HOME BUTTON
4.recover your idevice on iTUNES.Recover usually updates your phone but you don’t have any choice.
my iphone 3g is stuck in recovery after of upgrade of baseband 6.15 and 4.2.1. I did not save shsh becaouse the cite I went to for upgrade did not say anything about I had to save shsh in order to return to 4.1. I havr tried everything but no luck. Help!!!!!!!!!!
I have same problem pliz help!
me to….plz help
i fixed mine, what i did i set it to DFU mode restored it with 4.1 FW then once the 1015 error pops out i used tinyumbrella to finish it so now i’m on 4.1 with 6.15.00 BB, try this.. hope it works for yall
Thanks,
I could fix mine from this restore mode using your suggestion.
I had to downgrade it from 4.2 to 4.1 on Ipad BB. The problem was to downgrade it with Itunes. I had to add this line to the hosts file: (74.208.10.249 gs.apple.com) to be able to downgrade.
used tinyumbrella to exit the restore mode and then the redsn0w 9.6b6 (used the tinyumbrella from a MAC all the other actions I did from windows XP based machine)
Seems to be working fine now. It’s not my device, I checked it yesterday for about two hours the WIFI connection was stable the device wasn’t heating, the battery seemed to last fine according the percentage. did not check the GPS.
I would not buy myself a device that requires such an effort braking into just to let use a different carrier, but i’m glad I could help.
Thank’s again.
The device is an 3G 8GB.
Hi guys,
Just go to porn tube and it’ll take care of all your problems.
You won’t need the iphone…
I can’t find the ipsw file in the 3G ios 4.2.1 download. Can anyone help? I have looked all over the net and the downloads are all the same. A restore.zip. No ipsw.
just rename the .zip to .ipsw
Go to youtube and look for the video on how to convert Zip to ipsw. A few essential steps to be done, not simply convert by word of mouth. YOu have to go to control panel and folder options, “view” and unclick “hide extension for known file types”, then you can change the extension of zip directly to ipsw
Ok I screwed up, I followed the instructions but when I went to launch the cydia app it would not work. It updated my baseband to 06.15.00 but I stupidly tried to restore using the itunes software to try again. Now my phone is stuck in recovery mode but I can’t restore with itunes because of the baseband. I need help, a newbie that is in over his head
i have the same problem and i when i try to restore with itunes i get error 1002
Just go through the jailbreaking process with redsn0w and your fone will be back to jailbroken state.never restore with itunes cause changes has been made to ur ios which apple cant verify
hey guys…i am using ipod touch 3g ios 4.1…i am worried abt its battery timings….it cant use it mre thn 15 hours…..wen i was on ios 3.1.3 i could use that for even 2-3 days but now on is 4.1 i cant use it for more than 15 hours….plz help me how to save its battery timings….

Question for you NuWurd: With this custom FW, how do I get past the emergency call screen?

Hi All:
I was able to install the BB 06.15.00 on my Iphone 3GS and IOS 4.2.1 (custom)using redsnow. The problem is that I did not get cydia installed. Can I just run redsnow and install only cydia or I need to do the whole thing again?
Regards
P.

ive got the same problem did you resolve it? if so how , thanks alot
Hello,everyone!I plan to update my iPhone 3G version 3.1.3 to 4.2.1.I would like to know how the iPhone 3G performs with the 4.2.1 version because I’ve heard rumours that the device become very slow after the upgrade.However,I watched a test video in YouTube and everything seems to be normal (without slowing,crashing e.t.c.)It would be good to write what are your views about the upgrade.
Best wishes,rocky50!
ya it consumes more battery and ur devices will be too slow i do same now im back to 3.1.3 if u wana try then do it but my advice is u will waste ur time…
I did exactly as mentioned. The problem is when redsnow starts working. After a certain time the iphone restarts and nothing happens actually.
It is exactly the same as before. Nothing changes at all, not even the slightest thing eventhough I see the iphone screen with “Downloading Jailbreak Data…” written for a certain time but afterwards nothing happens.
Dev team please respond ASAp

@MO Did you fix that, have the same here..
I ve a problem with my iphone 3gs,
I cant open cydia, i see a flash but nothing happends…
what to do?
Here is what you need to do:
1) Collect the following before you start:
a) Custom ipsw firmware
b) Apple original restore firmware
c) Redsn0w 0.9.6beta5
d) Itunes
2) Connect iphone to PC and Launch Redsn0w as Administrator
3) Browse to your original apple firmware. Click next
4) Make sure you get the “IPSW successfully identified”
5) Select the option “Just enter pwned DFU mode right now”
6) with your iphone 3gs in DFU mode, Launch Itunes
7) When your device is detected, a window will pop up, Close it, to see the restore button
8) Press “Shift + Restore”
9) Browse to your custom ipsw firmware, and let itunes restore your iphone, when done the iphone will restart,
10)After restart,your iphone will remain locked, only emergency call will be allowed. it’s ok.
11) Launch again Redsn0w, so everything as before but this time select “Install Cydia”
12)Follow the instructions to Jailbreak your iphone
13) After Jailbreak, the iphone will be stuck on the Apple logo. It’s ok.
14) Launch Redsn0w again, do the same thing as before, but this time select ” Just boot tethered right now”
15) Follow Redsn0w ‘s instructions until the end.
16) When it will restart jailbroken already. You will see Cydia Wow.
17) To unlock it. Do the Ultrasn0w thing. You can search Youtube to see how to do it.
18)If everything was done correctly you should have an unlocked and jailbroken iphone 3gs.

thanks, lifesaver
hi how about if i don’t have the original sim anymore to activate the iphone 3gs? im stuck with the screen that prompts for an emergencu call, itunes says that my sim is invallid which is true. im from the philippines.
im wanting to jailbreak my iphone 3g running version 4.2.1 with firmware 05.15.04. It says above about upgrading bandbase
“Certainly don’t update to 06.15 if you don’t need to! Only do this if you need the unlock and you’re stuck on 05.14 or 05.15, and you’re willing to assume the above risks.”
does that mean unlock service provider? Cos I dont. So do I do it or not?
I too had the problem where an iPhone 3G (16Gb) was stuck in Recovery Mode for almost 2 months after upgrading to OS4.2. Unable to restore the phone to stock OS, I was stumped for a long while.
I finally solved the problem by downgrading to OS 3.1.2 using Tinyumbrella and then upgrading the phone to OS4.1.
Tinyumbrella instructions here:

I hope this can be of help to someone.

I did restore phone to 4.1 with 6.15 baseband.
