Dev-Team Working on Downgrade Baseband 06.15.00 to 05.13.04

MuscleNerd, in tweet, hints that they are working on downgrading Baseband 06.15.00 to 05.13.04. In a reply to one of his followers, Musclenerd says that they are working on downgrade iPhone 3GS baseband 06.15.00 to 05.13.04 rather than an unlock for baseband 06.15.02, 05.14.02, or 05.15.04.

Someone asked MuscleNerd in a tweet; “what about people with 3GS firmware 4.3.1 and baseband 5.16.02? How long do we have to wait to unlock our devices 🙁 i hope soon”. MuscleNerd responded in two tweets:

for those at 05.14, 05.15 or 05.16 I really don’t see an unlock coming. Rather, it’ll be: update to 06.15, then down to 05.13

(because the downgrade from 06.15 goal is much higher priority than explicit 05.14,05.15, or 05.16 unlock. Achieves same.)

So the idea is, there won’t be an unlock for iPhone 3GS baseband 05.16.02, 05.14.02, or 05.15.04.Rather, dev-team is working on a method by following which, users with iPhone baseband 05.16.02, 05.14.02, or 05.15.04 will update their baseband to iPad baseband 06.15.00 and then downgrade baseband 06.15.00 to an iPhone unlockable baseband 05.13.04.

We’ll update you as we know more on this baseband downgrade hack. Stay Tuned!

when do they update ultrasn0w version to fix fw 4.3.1 with 5.13 baseband?

caicaihello November 7, 2011, 11:27 am

I think the old version of ultrasn0w is better for your iphone.Because your baseband is 05.13

caicaihello November 7, 2011, 11:25 am

you can just update your baseband to 06.15.00,so you can unlock your iphone.The only disadvantage is that you will lose gps function.

drchandoo April 10, 2011, 7:58 am

Education? November 19, 2011, 8:34 am

You have got to learn how to:
a) Use grammar properly
b) Learn to spell like an adult
c) Not look like a complete moron\douche by typing like an asshat
d) All of the above

The answer is D

Great….

Harry Nguyen April 10, 2011, 1:55 pm

This is all I need, the stable unlock already in place and by accident there are a lot of people get the unwanted baseband installed in their devices. I wished I will get it sooner (I got 2 devices and sold 1 with a loss because of the waiting time for the unlock.) from MuscleNerd, Thank you for all of the works you done for this community.

hamiexz April 10, 2011, 2:37 pm

elturo81 April 12, 2011, 11:21 pm

Excellent!!!! my 3g doesn’t work Properly since i updated the baseband to 6.15.0 even if i do a restore on it, i actually i’ve done that 3 times already and still have the same issue.

So hopefully they’ll come up with a solution

Thanks dev-team

lenjung April 13, 2011, 4:10 pm

i have a 3gs IOS 4.3.1 with base band 05.16.02 and looking to unlock it. Please let me know the procedure once the downgrade from 06.15.00 to a baseband which is unlockable is available.

thesaipankid May 7, 2011, 8:29 am

Hi,

tony May 10, 2011, 6:59 pm

hi there I look too for downgrade from 6.15.00 and stil waiting 🙁 my GPS doesn t work

Anon E. Mouse May 11, 2011, 5:42 pm

I can’t believe this downgrade hasn’t been released yet… Dev Team does realize they’ve crippled tons of phones, right?

Pete May 17, 2011, 12:57 pm

I have bought Navigon on app store for complete EU, and now I can’t use it as of bloody 06.15.00 BB. Please help me out to get rid of that BB…

mmrq May 18, 2011, 7:52 pm

C’mon! Please let us know if this Unlocking the IPhone 4 with new baseband is even going to be available. Just bought the new iphone 4 only to learn that it has a new baseband and cannot be unlocked at this point. Just waiting for an unlock from Dev Team, Cannot wait. Please update the status. Thanks

Pete May 19, 2011, 2:11 am

Mmrq May 29, 2011, 11:05 am

Any update?

Pete May 29, 2011, 6:07 pm

After all I don’t need unlock as much I would like to get my GPS back 🙁

Help us dev-team, please!

Maxvergio May 31, 2011, 2:20 pm

You can simply buy a gevey pro sim( if u really can’t wait) and gv the dev team tym to sort the unlock out permanently….. Even free stuff fun cm cheap r easi…

tan June 3, 2011, 6:15 am

How do you exactly use gevey pro sim in 3gs? To the best of my knowledge it is only meant for iphone 4, unless I am missing something here. if you know how, please post instructions on how to use gevey pro in 3gs.

macwoods May 31, 2011, 4:54 pm

Can’t wait too, it’s been now several months without gps, and i really could use it since i have Navv. And more recently, trying to fix his and following some instrunctions i found on tne redmond pie site, resetting the the network settings left me with no mms. So i it’s bit of a pain in the ass right now 🙁 Keep up the good work Red Dev!

OK June 3, 2011, 2:08 pm

I had no GPS for SIX months. Even a fix had not been issued.

I give up wating. I will sel this piece of shit

I think Jobs wins and Devteam lost.

kiltrik June 7, 2011, 8:44 pm

And what with 3G, do they will be able to downgrade 6.15.00 ?

daniel angel June 16, 2011, 12:15 pm

no service problem with iPhone 3GS 6.15.00.

OK June 17, 2011, 4:52 pm

I really miss my blinking blue dot on my “Maps”….

cclaudiu June 18, 2011, 2:41 am

yeah, finally i think i ll be selling this iphone, and i ll switch to a galaxy… i ve been waiting since dec 2010 for a downgrade from ipad…and nothing…
the stupid thing is that when you buy an iphone you just dont know all the underlying stuff…
Keep it like this DEV team and you ll get a lot of customers…or do you?

Rcfresh July 6, 2011, 6:47 pm

Is there no way the Dev Team could allow an unlock for the 3gs with basebands 05.14.02, 05.15.04, 05.16.02. I am so desperate now, and updating my firmware to 06.15. is just too risky and it doesn’t work for me. I’m so desperate.

TAYAB July 14, 2011, 2:30 am

honesty July 17, 2011, 2:54 pm

I recently upgraded to ipad baseband with my iphone 3gs on 4.3.3 and used cydia to install ultrasnow and my iphone 3gs was working perfectly. I was setting password for my device and i tried putting my passcode again, it says wrong code.
i tried restoring with my itunes, but it gave me an error 30194.
i used diskaid to open to go to the library, keychain, and deleted the keychain dbs and later deleted the whole keychain folder.
my problem became worse now that i entered my password again and it iphone says iPhone is disabled…connect to itunes.
when i connect to itune, my itunes will request me to unlock my iphone first to be able to pair with my computer.
i kicked the phone to udf mode and tried SHIFT + restore to restore but it fails to do so and brings out error code 30194.
please i need your help cos this is my only phone and i don’t want to loose it. any help from you guys will be highly appreciated. thanks
Honesty

saschagsx October 6, 2011, 6:55 pm

Who knows how things are going with downgrade iPhone 3GS baseband 06.15.00 ??

scottmitch October 7, 2011, 7:40 am

All hack’s will be released after iOS 5 is launched [Releasing the hack’s any earlier could result in them being blocked if Apple get’s hold of them]

chello October 9, 2011, 1:11 pm

While we are surfing Tweets of the famous iPhone hacker MuscleNerd , we we have found a really interesting information.The iPhone Dev Team is close from release the solution to downgrade iPhone 3GS baseband from 6.15.00 to 5.13.04 to fix to fixGPS problem on iPhone 3GS.So that, it’s highly expected that downgrade 6.15.00 baseband to fix GPS problem is almost completed, but as usual all hackers are holding their major hacks, jailbreaks and unlocks after iOS 5 release to keep them away from Apple hands.

machinegreeneus October 9, 2011, 3:54 pm

Any news about the downgrade from 06.15.00 to 05.13.04 for iPhone3?

Are they now holding till iOS 6 gets released? Whewww…

Dev Team, just let us millions know if its possible to downgrade the 3GS baseband from 6.15 to 5.13.

hamid November 20, 2011, 9:35 pm

well its been more than a month since iOS 5 released and now iOS 5.0.1 also released, when do we expect downgrade for the iPad baseband? atleast any roughly idea, devteam????

proopps December 9, 2011, 12:29 pm

Will it be possible to downgrade iPhone 3G 06.15.00 with the same platform you will be using for iPhone 3Gs?…Some of us wish so…or someone help us with a tweak that will fix gps.Thank you in advance.

ESCape December 13, 2011, 6:05 am

I read that… those of us with the newer bootrom on our 3GS iPhones should not upgrade our basebands to 06.15.00 as it will brick our phones by frying the radio i.e. physically damage it. If that’s the case I hope we well be able to downgrade straight from 05.16.02 and 05.16.02 (specifically the latter in my case), or we’re pretty much S.O.L. on the unlock front unless some future baseband we can upgrade to becomes unlockable.

ESCape December 13, 2011, 6:07 am

typo there… obviously meant 5.16.01 and 05.16.02

frankoli December 15, 2011, 12:23 am

i really apreciate devs work on this and of course we are all in a rush to get results, as we should be…. we have been seeing promises of a downgrades from baseband 6.15 on 3gs for over a year. as far as musclenerds hints on twitter, a lot of speculation, but no results so far, it seems now the excuse is that we will have to wait for ios 6,7,8,9,10…..and so on

frankoli December 15, 2011, 12:26 am

those redsnow guys really messed up but don’t seem to be worried at all about fixint the 6.15 baseband issue on 3gs. as far as i go those guys are not even devs, their missfits. they ruined iphones all over the worls, we se nothing but people complaining about their mess and they don’t even bother fixing it…. dam for all i know they keep acting like nothing ever happened

GTFA February 2, 2012, 8:13 am

Dude don’t be rude!
1. All modification of your device is done by you, not anybody else and u act at your own risk and no warranty from any of “Dev-team” members.
2. Dev people are just ordinary hard working hackers (like me) who are just doing this to help us out and free us from Appleization.
If you cant wait do the research before u update or sell your goddamn phone and get u self a Android (like i did). But then you get Google in your pocket.

Kind regards
(If you can’t beat the system, you have to join it)

proopps February 8, 2012, 7:30 pm

Like that,keeping that fool straight….idiot…You don’t know if you can use the same platform for 3G?I am in Africa man…to get my iPhone was a dream for me…I would like it to work proper…My GPS is all mess up..MY fault…I had hope that you guys can reverse things once you play with it…as you always do.

naresh.zues February 10, 2012, 7:35 pm

it has been almost a year.hope they release the downgrade soon…

xtz March 10, 2012, 6:58 pm

iPhoneHeat March 11, 2012, 12:26 am

BB 06.15.00 downgrade/upgrade is NOT possible to date.. you’ll have to live without GPS

xtz March 11, 2012, 11:38 pm

not even in the future won’t work? its forever closed? damn apple’s software’s r so bad.

gonay May 5, 2012, 11:11 pm

Bonjour, j’ai un iphone 3gs basband 6.15.00 et version 5.0.1, j’ai mis l’ipad baseband pour le desimlock et mon iphone s’éteint tout le monde quand je l’utilise.
et j’ai une autre question, si j’ai mis l’ipad baseband, est-ce normale que j’ai encore le Prog. du modem qui affiche 6.15.00 et non 6.15?

Merci!
