  • Hello, I have a clean unjailbroken iPhone 4, ver. 4.0.2, baseband 01.59.00.

    It is December 11 2011 today. I was wondering if I can selectively upgrade to 4.2.1 only using tinyumbrella+greenpois0n while preserving bb?

    I've read somewhere that says once Apple stopped signing 4.0.2, I can't upgrade to that firmware and my only option is upgrading to the latest one. Can you confirm that for me? Thanks!

  • Hi can i follow this procedure to update my iphone 4 to ios 5 and preserve my baseband? thanks

  • If you guys wanna unlock an iPhone then I would suggest that U look over on this place: SoftUnlock. com It's free and it does the trick!

    iphoneunlatch . com

    Unlocking iphone never? been so easy. Jailbreak/Unlock all version iphone 2g,3g,3gs,OS4 and ipod easy way. This is a only software can unlock your iphone.

  • I figured that I would do some homework of my own on the subject.

    Here is what I came up with. If ya want to unlock an iPhone the best free way is with SoftUnlock. com

    If you are wanting to jailbreak iPhones then I would say go with softjailbreak. com My favorite part is that they are absolutely free.

  • Does this work with the iPhone 3GS?

  • Hey Mike. Just wanted to let you know that I was able to successfully upgrade to 4.2 from 4.0.1 without updating the baseband. This is the perfect video . I got this video after exploring atleast 100 of dem.

    A real good work from you. Thanks a lot.

  • I was an iPhone nOOb then I decided to get to the bottom of things.

    Here's what I came up with! I would say use softunlock. com Want apps for free? just go with softjailbreak. com

    Here's the kicker: they're 100% free.

  • i dont get the unlock part.. u just upgrade essentials to unlock?

  • @jcXshi follow the lasted guide I have. you can only unlock with UltraSn0w if you have modem firmware 01.59.00. there is no unlock out for any other basebands.

  • @mwittchow i have an iphone 4 version 4.2.1 baseband 03.10.01.. what should i do? and if i upgrade to 01.59.00 can i still downgrade. will it do harm on my device?

  • @jcXshi you will not be able to unlock 03.10.01 at this time sorry.

  • Comment removed

  • @jcXshi upgrade essentials and then download the package UltraSn0w, which is the unlock.

  • is there a way o change baseban ?

  • will this work for my iPhone 4 version 4.1 baseband: 02.10.04??

  • @thesuperawesomejerk you can jailbreak, but there is no unlock for your baseband yet.

  • I am keep getting freaking 1604 error ,, I am on the 4.0.1 (8A306) - My base band is 1.59.00. And the funny thing is i have tried so many times , and the same thing!

    And by the way , after last time i got 1604 error, i opened GreenPoison and no matter what tried to follow steps ,, it crashed , iphone did give me anything besides "HANGING IN HERE" and thats it.

    And here is the most important - after it crashed i am able to start up my phone as previous like nothing happened. still jailbrake

  • i need help! Okay so i need to unlock my iphone 4 because i have tmobile. Right now it's on version 4.0.2 and modern firmware 01.59.00

    Can i unlock it? do i need to upgrade to 4.2.1

    I'm new to this and i really want to learn how to unlock my own iphone 4 and you seem like the only person on youtube who knows how to do this

  • @GoldenGirl1314 no problem. you can either jailbreak it first and then run Ultrasnow and you should be fine. if you decide to upgrade to 4.2.1 so that you can have features like Facetime, then you follow the tutorial above, and it should work, it worked for me today.

  • @dye4him but if i want to have features like facetime then i do need to upgrade it right?

  • best way to unlock? I have a standard iphone 4 on 4.2.1. I'm heading the Europe for two months so I'm putting my AT&T account on hold and my idea is to back up the iphone to itunes, then unlock it to use with a UK carrier. Then when I get back I'd just restore from my backup to set things right again.

    I'd like an option to leave it unlocked and still use with ATT if possible too?

    I'd like to be able to back it up to itunes while in Europe; should I create a new itunes profile for this?

  • First of lemme say this works great I am running 4.2.1 with mt 01.59.00 baseband and all's good but the only problem I'm having is that I can't activate facetime every time I try to it says "Waiting for Activation" and stays like that for ever. Can someone help please?

  • Im hanging with iPhone 4 ios 4.2.1 baseband 02.10.04 with jailbroken any chance to unlock?Please help me..Thanx

    can i unlock to use diff. sim ??? please help

    actully just now i hav jailbreak it and download cydia but its not wrking

  • Pick your backup and click the "Continue" button to restore your phone. Some will argue that after Jailbreaking, you should select "Set up a new iPhone" - however, doing this will lose all your saved data. Restoring from a backup will still unjailbreak your iPhone, but leave your data intact. You won't be able to tell it was ever jailbroken.

  • DO NOT SELECT "Set up a new iPhone" IF YOU WANT TO RESTORE - NOT doing this will LOSE ALL YOUR SAVED DATA. Pick your backup and click the "Continue" button to restore your phone.

  • Comment removed

  • @IPassionI yes push notifications will work if you activate with an ATT sim card even if it is a dead sim.

  • I have the same thing iPhone 4 BB:1.59.00 and a dead AT&T SIM card,,, so if I do this tutorial does the push notification work?

  • i didnt get the 01 95 00 baseband y

  • @NoScopedAgain you didnt have that baseband to begin with before the tutorial or you did not follow the instructions correctly and there was an error when and if you started the TSS server.

  • @mwittchow oh i have baseband 03.10.01 could i still do this

  • Did all that but didnt work now is asking me to restore the iphone, I click restore and it says are you sure you want to restore and update???? what should I do??

  • @SiroHunter only restore if you have have the TSS server running with no errors.

  • I got an iphone 4

    FW 4.2.1

    BB  03.10.01

    And for some reason it works with T-Mobile.

    Any reason?

  • @kilme39 you have a factory unlocked iPhone like me! they are not locked to a network so that you can use them worldwide.

  • @mwittchow yesssss! thank you for your help I really wanted to know

  • @mwittchow Where can I get factory unlocked phone from?

    ):

  • @famousfakir Canada is usually the cheapest. Check eBay and look for Officially unlocked iPhone 4.

  • So I have my iphone 4 with 4.1 with 01.59.00 baseband with ultrasn0w working like a charm, but want to update to 4.2.1, if I follor this tutorial will the ultrasn0w still work? thanks for the great video btw!

  • @SiroHunter yes this is how i updated the iphone in the video.

  • My iphone 4 software 4.2.1 with 03,10,01 from america is jailbroken but is must be unlock! HOW ??? please HELP ME !!

  • @jastmi12 no unlock yet.

  • i just want to tell you i LOVE you and your video saved me hours of watching dumbasses make tutorial videos and they just end up screwing everything up so thanks soooooooooooo much you are the shit!!!

  • Have you seen any cases where the JB failed (screen stayed black when pressing JB on greenpoison RC5 b4.? I followed the instructions to a T. Tinyunmbrella TSS server on, had the correct 1013 error after restore, so I am not sure what is up and where to go from here. Help!? BTW, using windows version of GP RC5 b4. Thanks in advance!!

  • @rainman4195 try running greenpois0n as administrator.

  • @rainman4195 Did not realize there is an option for admin. Can you provide more insight on how to do this? Also, I have seen some tutorials where they exit recovery on tiny umbrella before running greenpoison (TSS server still running though), do you recommend this? Same with restarting iTunes before running greenpoison, some say that it should be running, so after greenpoison shuts off iTunes, some say start iTunes again before running the jailbreak. Thoughts on this and the admin question?

  • is there any chance to unlock baseband 02.10.04? maby some days?

  • I have an Iphone 4 Version 4.2.1 and Modem Firmware: 03.10.01, is there any way could be unlocked? Please advise. Thank you.

    Carrier's Telstra 8.1

  • hello i have a t mobile sim card after i restore and jailbreak with greenpoison can i use it to activate my phone and start using it? thanks.

  • i jailbroke my iphone 4 firmware 4.2.1 and baseband 03.10.01 using green poison .. everything works fine and dandy. but when i try using ultrasn0w 1.2 to unlock it to use my local sim card ? i cant..

    help me out here bro.... can we unlock 03.10.01 ? .... and how the hell do i do tht it sucks having a good phone and not being able to make calls and msgs :( :( :(

  • @spilverfly you cannot unlock it yet. you will have to wait for a new unlock which will come out soon after iOS 4.3

  • My iPhone 4 software 4.0.1 is jailbroken & unlocked in UK with a cut down O2 sim in the tray. Can the process be done with this sim in the iphone or do I have to put the original vodafone sim in to carry out the JB & unlock?

    Thank you.

  • @warmywhite you can use your O2 sim. You will have to hacktivate it. To do this just run redsn0w right after greenpois0n. If you have any Vodafone sim cards those will work better as you will get legit activations for push notifications and what not.

  • i get 1064 error!! please help me..

  • What about the 2.10.04 baseband? Any rumors? I've heard that it is coming tomorrow! Please reply.

  • @QUEENofVEGAS it wont be released until after iOS 4.3 which will be sometime next week most likely. us developers still have not received the 4.3GM yet.

  • @mwittchow though is there ANY other way to unlock the iphone 4 on ios 4.1 and baseband 2.10.04?

  • crap! i went through another tutorial and they never told me to start tss server.. just save ssh...

  • can u unlock iphone 4 baseband 3.10.01 with this?

  • @omanboy12 That baseband is not unlockable yet. You will have to wait till iOS 4.3 is out. This is when the Dev Team will release an unlock.

  • @mwittchow Will the unlock for 3.10.01 come ever??? iv been waitin fr a month now....i need help bro

  • I keep on getting the 1604 error no matter what I do. I have an iphone 4 on 4.1 with baseband 1.59.00. I've tried restoring on a mac, windows machine and another mac but I keep hitting the same problem. I tried doing it both in DFU mode and recovery mode but still the dreaded 16xx error. I hope someone can help me with this. Thanks in advance.

  • do you need to be in ios 4.0 to do this?? please reply!!!

  • @doideraahh 4.0, 4.0.1, 4.0.2, will all work.

  • @FlareDragon27 yes just rerun this tutorial

  • I LOVE YOU!!!!!!! THANK YOU!!!

  • Dude, thank you so much. I was using TinyUmbrella to kick it out of recovery mode, but it kept going right back in after reboot. I didn't think about loading GP straight from the DFU mode. After following RedmondPie's guide 10 times, and failing each time, I was this close to pulling my hair out, or worse yet, just restore all the way and lose my 1.59 baseband. I don't need the unlock, but prefer to keep it for resale value. Anyway, you saved my bacon, so thanks again.

  • dude it didnt work for me :( i keep getting errors n cant restore it now :( i've been waiting for the unlock for 6 months now and i think its F*cked:( help me please how can i go back to normal ?? or restore it ?

  • Hi can you tell me if you can unlock the iPhone 4 on firmware 4.2.1 on baseband 03.10.01 I can't find the unlock anywhere :( if there isn't one can you tell me when there will be one. Thanks

  • @soljahofallah786 this tutorial is to save your baseband.... if your phone start out with baseband 03.10.01 then your out of luck. unlock wont be out until apple release firmware 4.3

  • @ohnoperiod ¿ i have the iphone 4 whith 03.10.01 baseband ,is there a problem if i jailbreak now ??

    if i jailbreak now i will be able to unlock when the 4.3 is out ¿??

  • @soljahofallah786 no1 knows when theres gona be an unlock follow the devteams website because they are the ones who release unlocks

  • @theteacake I made the video tutorial after I tried it once for myself. I was on 4.1 initially.

  • you were already on 4.2.1 though...

  • @DrPancakePHD That baseband is not unlockable yet. You will have to wait till iOS 4.3 is out. This is when the Dev Team will release an unlock.

  • The jailbreak worked fine and the unlock I THINK worked fine aswell. the problem is the name of my carrier appears 02-UK (fine)..but I have no signal...and I got a message on the screen sayng...WAITING FOR ACTIVATION this may take some time...Ive tried to put the micro sim on and off. switch the i4 on n off, connnected n disconected...do u have any idea what this could be????

    just to let u know the micro sim Im using was a normal sim Ive cut it to a micro sim...+D

    thanksss

  • @djbrunocamargo28 the waiting for activation thing will only work if u have an AT&T sim heres what you do

    when you're at the waiting for activation screen turn of the iPhone and run redsnow it should hacktivate the phone then through Cydia install ultras0w and all should work..Worked for me

  • nice video

  • Can you make a video for the 3GS aswell? Thanks

  • I'm still on 4.1 with 2.10.04. Should I use this method to reach 4.2.1. If I don't follow it, iphone will upgrade my BB?

  • is it work with iphone 3g 4.1 firmwire baseband 06.15.00 MB model??????

  • @djbrunocamargo28 This tutorial is for the iPhone 4 only.

  • worked perfectly...=D thankssss

  • Is it necessary to 'Set up as a new iPhone' , can I restore from my backup?

  • @FlareDragon27 it is not necessary to set it up as a new iPhone but whenever you upgrade to a newer firmware it is better to. If you notice bad battery life I recommend setting it up as a new iPhone.

  • Comment removed

  • @FlareDragon27 you can download a program from cydia called appbackup I believe. It will let you save your appdata and restore it later on. So for Now go ahead and restore from a backup and if you notice battery problems restore and set up as a new iPhone.

  • @mwittchow thx a lot ^^

  • @mwittchow just one last question. if i get battery problem and i have to restore and set my phone as a new one, will i have to start over all the 'upgrade 4.2.1 & preserve bb' process?

  • Comment removed

  • Dude I have an iphone 4 version 4.1 with baseband 02.10.04 I need help unlocking it!!!!!

  • @pityalomeri you cannot unlock the baseband yet. Once 4.3 is released the iPhone Dev Team will release an unlock that will support 4.1+

  • :D THANKS BRO THANKS YOU ARE THE BEST DID IT !!!!!!!!

  • @yoyodog32 if you got the error 1013 when restoring you are doing it right. Read the instructions and watch the video.

  • i didnt work for me :(

  • @KounterMusic the sim is dead so that number is not in service.

  • you might wanna blur your phone number.. -_-

  • will this work with the iphone 3gs?

  • @iidabomb29 this tutorial is for iphone 4 only and will not work with the 3GS. I will make another tutorial later for the iphone 3gs to get to 4.2.1 untethered.

  • Great video THANKS A LOT!

  • Good tutorial. Do I need the official simcard to activate the phone after installing Greenpoision?
