——————————————————————-
Method #2 (Supports iOS 5.1.1):
At posting time, the latest ultrasn0w is not yet supported on iOS 5.1.1. Thus, you must intall an ultrasn0w fixer patch first.
12. If you’ve installed ultrasn0w, remove it now.
13. Launch Cydia.
14. Add the following to your source:
http://repo.iparelhos.com
NOTE: If you get the following error message while trying to add repo.iparelhos.com the following tutorial will help you in fixing repo.iparelhos.com error “The indicated repository could not be found. this could be because you are trying to add a legacy installer repository (these are not supported). Also this interface is only capable of working with exact repository URLs“
15. Tap on the iParelhos repo to see Ultrasn0w Fixer for iOS 5.1.1 utility. Tap install to begin installation.
16. Once installation is complete, we need to install ultrasn0w. Launch Cydia.
17. Search for ultrasn0w on Packages in Cydia. If you cannot find it, add new sources by typing ultrasn0w repo:
repo666.ultrasn0w.com (with zero, not o).
18. Install Ultrasnow 1.2.5.
19. Reboot your iPhone.
20. Turn off 3G and insert your SIM card. It should pick up your carrier signal.








Hi
I have an iPhone 3GS with 05.13.04, 5.1.1 OSX,and with T-mobile network. It works, I have network, but only if there is 3g network. Whenever I try (or need) to switch to edge, the device does not find any services. Because of that the GPS is inaccurate too. I tried to reinstall ultrasn0w, but it doesn not help. Any suggestions? Thanks in advance!
You might want to upgrade your device to latest iOS while preserving your baseband and then jailbreak it and install ultrsn0w

hi I have iphone 3gs .which i had upgraded to 5.1.1 ver and firmware 6.15.0 but when i tried to add repo.iparelhos.com in cydia its showing repository error(the indicated repository could not b found.this could b bc u r trying to add legacy installer repository{these r not supported}Also this interface is not capable of working with exact repository urls)
plz help …………
Try to add it at different times as sometimes their servers get overwhelmed with the huge about of requests at onetime. If you keep trying it will eventually work.
Hello, I have added repo666.ultrasn0w.com to the sources, but when completed it is not there. Every time I get No Service. I have iphone 4S with 5.1.1 Modem firmware 2.0.12.
Please help in this.
Ultrasn0w does not support iPhone 4S.
Did not find repository – the indicated repository could not be found. this could be because you are trying to add a legacy. also, this interface is only capable of working with exact repository url
HELP ME !
what is the url you are entering please?
i have the same problem i have an iPhone 3gs running 06.15.00 baseband. HELP
what is the url you are entering please?.
I am repeatedly adding http://repo.iparelhos.com but the cydia replies “the indicated repository could nit be found. this could be because you are trying to add a legacy installer repository (these are not supported). Also this interface is only capable of working with exact repository URLs.”
We just posted a tutorial on how to fix rep.iparelhos.com error
I have the sale problem with My iPhone 3Gs with 5.1.1 iOS , what can i do to solve this ??
Occasionally you will get repo errors. Usually due to the repo being down for maintenance.
IPhone 4

iOS 5.1.1
Baseband:04.12.01
still no Service
Plz help
Method 2 done
but no service
There is no unlock solution for this version as listed in our website you can only jailbreak it and install cydia.
Hello.
I jailbroke my iPhone 3Gs version 5.1.1 with baseband 6.15.0 from redsn0w
As a result. I could not get service and could not install Ultrasnow because it hoes “Error Date Format”
Someone recommended me to jailbreak my iPhone again on redsnow 0.9.14b2 and then downgrade modem to 05.13.04. And so I did but it had same results.
I haven’t tried your steps yet and I just have to ask first:
1) Do I need to upgrade it again to baseband 6.15.0? If yes, how will I do that?
2) Will process #2 work even if I don’t upgrade my baseband firmware from 5.13.04 to 6.15.0?
3) How do you fix the “Error Date Format” in installing/Searching Ultrasnow in Cydia?
Before you do anything have you tried to use the instructions in Method #2 (Supports iOS 5.1.1): above to unlock your device ?
It finally worked. Thank you so much!
hey. hello again. It was perfectly working. And then I had to install Siri and my phone broke. I had to restore and do all the processes all over again. When I get to doing Method#2 again. I keep on getting errors. http:// 404 not found or something like that for both fix patch and ultrasnow. What do I do?
What is your device model, iOS versions and modem firmware version please?
Great .. thank you for the feedback.
help jalbreak my ipad using absinthe-win-2.0.4 but i cant install the ultrasnow showing note:the requested modfcations cannot be applied due to required dependencies or conflicts that cannot be autimatically found or fix. I HAVE IPAD 16GB 5.1.1 MODEM FIRMWARE 07.11.01,
Ultrasn0w is for iPhones only, you cannot unlock an iPad.
hi, i have the same ipad and i want to use internet by cellular services and the network is full but i cant connect to the server. if u have any idea about this, please reply
You might want to contact the Cellular data provider and ask them for the settings for your iPad.
hey, I jailbroke my iphone 3g from redsn0w 0.9.14b1
my version is 5.1.1
modem 05.16.05
I downloaded the ultrasn0w fixer 5.1.1 and then ultrasn0w and rebooted but it keeps saying searching or no service and I tried with 3 different sim cards but it doesn’t work. What should I do?
You need to upgrade your modem firmware version (baseband) to 06.15.00 first using the following tutorial:
http://unlocker.ws/blog/iphone-how-to/upgrade-iphone-3gs-3g-4-2-1-baseband-to-06-15-00-redsn0w
I updated the modem firmware to 6-15-00, and now all it says is no service
After you update to 06.15.00 you will need to use the instructions in Method #2 (Supports iOS 5.1.1): above.
I did exactly like the instructions said, I re-installed ultrasn0w fixer for 5.1.1 and It only gave my ultrasn0w for 1.2.7 so I re-installed that but it still says no service
please help me
Nevermind, I figured it out thank you for all your help though it did help
keep up the good work!!
Great .. thank you for sharing
.
says : cannot comply note: the requested modifications cannot be applied due to required dependencies or conflicts that cannot be automatically found or fixed
Try to update all the sources in Cydia if that did not work then We would recommend you to rejailbreak your device and start over again.

There is no unlock solution for iPhone 4S 5.1.1, ultrasn0w will not work for it.
iPhone 3Gs, old bootrom, 5.1.1, 6.15.00
I have tried over and over again, making sure that I have correctly entered the correct repo address for repo666. Everytime, I get GPG error, Failed to fetch, and some index files failed to download. I have used the iParelhos repo and got ultrasn0w fixer for 5.1.1 installed, but cannot find ultrasn0w after that. What do I need to do?
In your case you need to use method #2 sometimes it takes more than one try in several periods of times just because of the servers availability.
I am running an iphone 4 with 5.1.1
i followed all your steps successfully, though it is still reading “no service” or “invalid sim”
Are there any more steps i can try to unlock it?
