If you have updated your iPhone 3GS or iPhone 4 to iOS 5.1 (with preserved unlockable baseband) and still getting no service after installing ultrasn0w from Cydia, you have come to the right place.
Since the release of iOs 5.1 an it's jailbreak, dev team has not updated ultrasn0w to be compatible with iOS 5.1 and this is the reason why you are still getting no service even after installing ultrasn0w from Cydia. While you wait for the dev team to update ultrasn0w, you can make things go good right now by installing ultrasn0w fixer from Cydia that will unlock your iPhone 3GS or iPhone 4 in no time.
Compatible basebands for unlock with ultrasn0w:
iPhone 4
1.59.00
iPhone 3GS
Step 1: Open up Cydia and go to Manage >> Sources. Tap Edit and then Add and write down the following

To check baseband of your iPhone, go to Settings >> General >> About >> Modem Firmware.
Now let's unlock your iPhone. Before proceeding, uninstall ultrasn0w from Cydia and eject your sim card.
Step 1: Open up Cydia and go to Manage >> Sources. Tap Edit and then Add and write down the following
http://repo.iparelhos.com.
Click Add Source.
Step 2: Once the repo has been added, search cydia for ultrasn0w fixer for 5.1 and install it.
Step 2: Once the repo has been added, search cydia for ultrasn0w fixer for 5.1 and install it.
Step 3: Now search Cydia for ultrasn0w and isntall it.
Step 4: Restart your iPhone and insert your sim card. Since the jailrbeak for ios 5.1 is tethered in nature, you will need to boot it tethered. To do so, open redsn0w [Download Redsn0w] and go to Extras >> Just Boot.
That's it. Your iPhone should get service by now. If it still shows no service, let me know in the comments section below.

Redsnow won't allow me to "boot tethered" with out 5.1 firmware selected as default build.(manually selected ipsw)
Will boot after the firmware is selected through redsnow, but still no service after reboot.
Hi,
I´ve restored my Iphone 4 with using itunes and a redsn0w customized no_bb -ipsw. I also did jailbreak my phone using the very same redsn0w and installed cydia into it. Then I added the url mentioned above and looked for the ultrasn0w 5.1 fixer and installed it. After that I looked and installed the ultrasn0w and rebooted my phone using redsn0w.
I still get the no service text on the left upper corner...
Need help.

i got signal but the upper show me only one bar before with version 4.0 was full at same place
my iPhone 3gs is with 6.15.00 modem firmware and old bootrom. the only change after this process is that I have "Searching..." (all the time) instead of "No Service." Any ideas?
Hi, I got the signal but I see only one bar of the network. Any ideas ? Thanks.
Hello. I have the same problem that kmp. I've got the message "searching" all the time but no connection. Although i got my whatsapp running and everytime i change the sim, whatapp ask me if i want to change my number, so, in a way it detects the change of sims.
Thank u!!
No need to reboot Your iphone (3gs) after install fixer and ultrasn0w. Just put sim card back in and wait a few seconds. Tested.

using iphone 3GS baseband 5.13.04
naveen
works like a charm..thanks dude :)
have followed this procedure but is just keeps on searching:
Iphohe3GS
baseband: 5.16.05
=> upgraded to 5.1
=> jailbreak with redsnow
=> unlocked
=> installed ultrasnow fix
=> installed ultrasnow
=> rebooted
=> still no signal
Anyone?
@Steveb Baseband 5.16.05 is not unlockable...
Hi, I jailbroke my iphone 4 using redsn0w and unlocked it after. I followed all of your steps, and it still didn't fix the "No Service" problem. What should I do now? Thanks in advance for the advice.
@jacob what is the baseband of your iPhone 4? is it 1.59.00?
Hey! I had no service, I did all of those things, and now it sais searching. Mine is Baseband 5.16.05 and I read here it's unlock-able, so what should I do? Can I downgrade? I am ready for anything! Please, help!
@leonid..No, baseband 5.16.05 is not unlockable...you will have to flash ipad baseband i,e 6.15.00 on your iPhone 3Gs if you want to unlock it...but be WARNED! If you have iPhone 3GS 16 or 32 GB that was made after week 35 of 2011 or a new 8GB iPhone 3GS made after week 28 of 2011, don’t install iPad baseband on it as it will brick your iPhone,
i'm on 06.15.00 baseband and its not working :( I keep getting stuck in "searching..." and "no service" mode. any advice?
Something for 3GS users with BB 06.15.00 who still can't unlock their iPhones. I did full restore and JB, followed the instructions and it worked. Here are some links below how to fix it:

PS.
This fix includes changing your iPhone baseband to iPad baseband.
@dina Just fresh retstore ios 5.1 and install ipad baseband again..it will work

@snake85 use this guide to jailbreak your iphone 3gs http://www.ibl0g.com/2012/03/jailbreak-ios-51-iphone-4-3gs-ipad-1.html
after that you would have passed the activation process
thank you i hope it will work
Hi, i did all steps, but still is writing SEARCHING/NO SERVICE/LOW SIGNAL-1BAR. my iphone 3gs is new bootrom, baseband is 06.15.00. I tried to restore ios few times, did jailbreak with installing cydia with ipad baseband as well few time. tried to install first ultrasnow than ultrasnow fixer, but every time the same problem. Any solutions? Please help!
you are a legend mate. but please tell me what do i have to do now to stop it from happening again and that the factthe jailbreak i have just performed is a tethered and have to boot it everytime. i need do to remove the jailbreak you see as i am selling the phone
much obliged
@snake84 If you remove the jailbreak, you will again get stuck on activation screen..so jailbreak is your only option
@Rimis...Many iPhone 3gs users are having this problem...Try once more and if it still doesn't work, you will have to wait for the dev team to update ultrasn0w to be compatible with ios 5.1
@Admin... need to try one more time :( maybe you know when is coming updated ultrasnow?
and maybe you know, what can be a problem with microphone, its very quiet when i`am talking and disappearing sound, i changed a charging port, but problem was a same?any solutions?
is there no way i can make it an untethered jailbreak so i can turn it off without having to reboot it
@snake84 No there is no untethered jailbreak for ios 5.1 yet...try downgrading back to 5.0.1 (if you have SHSH blobs saved)
@Rimis Ultrasn0w will be updated within two weeks, I guess. and about the microphone question, I suspect there is a hardware problem in your iPhone
hi
my name is Ram and i have iphone 4 and modem firmware 04.12.01
installed 5.1 and jail braked with redsn0w_win_0.9.10b6
and clicked "just boot" and even then no service.... wat to do???? plzzz help
me staying in INDIA and using AIRTEL sim
Thanks in Advance
Ram
so what your saying is once there is an untethered jailbreak for ios 5.1 ill be able to go over the tethered jailbreak
@RAM unlock for 4.12.01 baseband is not available
@snake84..Yeah but untethered jailbreak for 5.1 is not coming anytime soon...
hi, how to unlock iphone 4 02.10.04 baseband? ultrasnow can unlock this one or no?
@rimis 2.10.04 is a iPhone 4S' baseband...and no, it cannot be unlocked using ultrasn0w but can be unlocked using R-SIM III
@admin, my iphone is 4, not 4`s, baseband is 02.10.04. i can unlock only with R-SIM III? maybe its possible to downgrade to 01.59.00 baseband?
@Rimis oh sorry..My bad..no, you cannot downgrade your baseband but you can use gevey sim to unlock 2.10 baseband...
@admin, yes its cheap m8, only few pounds :)
do you no when that will be and how do you downgrade without it breaking
@snake84 I have no idea about the ETA of untethered ios 5.1...and for the downgrading process, the following guide will help you out
Downgrade ios 5.1
Is there any hope that sometime soon it'll be possible to unlock an iPhone 4 with baseband 04.12.01? Or, if not, is there's anything I can do to change or downgrade the baseband? I just got this iPhone with 5.1, so I don't have any blobs to downgrade it to another iOS.
Thanks,
Juan
@Juan There is now news regarding 4.12.01 yet and there is no way to downgrade the baseband...feel sorry for you
@Anonymous Oh well, I guess now I have to go beg to the carrier... Thanks for the info.
@juan if you have iPhone 4 from At&t, you can get it unlocked fro free...just call them
Thanks it works for me , i did not have to reboot or install redsnow . unistall ultrasnow, install ultrasnow fix , and then install ultrasnow . got signal on my phone. thank you
thank lot for whole info at less not only me got a same prob ,,,,thank again i can settle down my self until dev team come as the hero
3GS - Jailbroken - 5.1 - 06.15.00 baseband
In Belgium on Belgacom, NO SERVICE
I see it is a problem with a lot of people.. is the best solution to just call AT&T (Pretty sure that is what it was.)
I don't get it though, my 'criteria' matches everything and this should be working.
Also, I do have Ultrasn0w Fixer and Ultrasn0w installed correctly and in that order. I have followed every step to a 'T' on all of these youtube videos.
No Service / Searching...
Anyone with an idea what it could be? I've also tried just about every other 'tip' i've read on blogs like these as well.
Update #3:
Now it recognizes when i don't have a sim card and says "NO SIM", the moment i put a card in, it says no service.
That problem was fixed after putting it in airplane mode for a minute or so.
But now I need it to recognize my sim card.
@Bill maybe you should wait for ultrasn0w to comeout which will be compatible with ios 5.1
@Anonymous
I have the latest Ultrasn0w.. 1.2.5.. it says for 5.1 in Cydia..
@Bill no, ultrasn0w is not yet compatible with ios 5.1
not works, my iphone 4 is ios 5.1 with 04.12.01 firmware.
@ken iPhone 4 baseband' 4.12.01 is not unlockable using ultrasnow..the only iPhone 4 baseband that ultrasn0w support is 1.59.00
PERFECT (=
thank you (=
Worked perfectly after a bit of frustration trying to do it without your fixer. Thanks man, your a life saver!
Dear,my prob is not different then above users.I have baseband 04.12.01, ios 5.1(9B176).

Hi
I have Iphone 4.0, IOS 5.1 with modem firmware 04.12.01.
I followed exactly the described steps with redsn0w but the NO SERVICE message is still there.
Do you have any suggestions how to activate the network?
Thanks
@Bill: Having the exact same problem and I don't know what to do.
For people who are still having issues, even after installing the ultrasnow fixer, make sure that you first Install the Fixer and then the ultrasnow. If you have already installed the ultrasnow, uninstall it totally, then install the fixer and then finally the ultrasnow. This should resolve the no service issue, however the signal bars would drop down drastically to one or two.
i have iphone 4 with version 5.0.1 and modem firmware 04.10.1 it shows no service again and again.it works for few hours den again shows no service den i have to switch it off and den on den hv to repeat all the steps of gevey sim.sometimes it works for many hours bt sometimes d network dropped after 10 mins.pls help me..its about 2 months m having this prob..

HI I have an iphone 3gs with 5.1.1 with modem firmware 05.16.05 after jalbreak and its on no service or searching all the time before upgrade was on modem firmware 05.13.04 and 4.2 working perfectly I have tried almost everything and I can't make it work please help.
Hi 3gs with 5.13.04 still no service
Thanks in advance
Yes!!! It worked! I tried everything and I thought I just had a bad phone or a messed up antenna. but the problem was that it just took longer to search for the carrier.
If it searching for one and says "no service" then it says "searching" right away, that's a good thing, it means it will eventually find it. Leave it for 10 minutes or more. I was going insane and didn't know I just needed to leave it longer.
Okay, I never post. As public service here was my solution.
I have a "newer" post week 45 or whatever it questions you with. I screwed up and updated to 5.1.1 via iTunes. It had 4.x.x on it and was unlocked and jailbroken and I got it from a guy that was using it with cingular. I have AT&T. I popped my card in and it worked but service was mediocre.
I updated to 5.1.1 to go "stock" and back to normal although I have had jailbroken phones in the past. I was hoping to obtain better service from the efforts. Anyway, iTunes but on baseband 6.15.00 with the OS update. I used redsnow 0.9.14b2 and added Cydia. I ended up with searching... and No Service. I have spent probably 8 hours over the course of a few days trying to fix it. I went to AT&T and also to Apple and long story short they couldn't help me.
So, newer 3GS which doesn't like 6.15.00 bb apparently. Success came like this:
01 - I used iTunes to do a fresh update to 6.15.00 and iOS 5.1.11
02 - I used redsn0w 0.9.14b2 selected the IPSW (look for guides on how to do a jailbreak/unlock with this) and then selected jailbreak
03 - I unchecked everything except for downgrade broadband and went through that whole process
04 - I then used the same redsn0w again and selected the IPSW per the guides and selected jailbreak
05 - this time I unchecked everything except for install Cydia
06 - it crashed
07 - I ran redsn0w again and repeated steps 04,05
08 - I went and looked at the general-about and it had BB 5.13.04! Also, the id code for the SIM was showing which it wasn't previously.
09 - I did as instructed with the ultrasn0w fixer and ultrasn0w as directed in this post we all have read.
That did it! I hope this helps someone!

ultrasn0w was solution for my no service problem.
There is no need to look for Ultrasn0w fixer 5.1 (it does not exist anymore, there is only 6.1),ultrasn0w 1.2.8 has it included.
thanks a lot!
