After yesterday's downgrade release of the 06.15.00 baseband for iPhone 3 / 3GS, many users were stuck with the no signal error. So here we are bringing you a solution to fix this problem.
After downgrading the baseband, you can unlock your iPhone 3/3GS, using ultrasn0w on a lower 05.13.04 baseband. The downgrade was implemented in the new redsn0w 09.14b1, and many users tried it.
Many of them faced crashes while applying ultrasn0w and also No Signal error. There is a simple way to fix the No Signal error on iPhone 3/3GS and other crashes as advised by the iPhone Dev Team. They have advised to reinstall Mobile Substrate and ultrasn0w. Here is how to do it with the Cydia package manager.
Fix No Signal Issue On iPhone 3 / 3GS by reinstalling Mobile Substrate and Ultrasn0w
Step 1: Search for Mobile Substrate in Cydia. Start Cydia > Manage > Packages.
![]() |
| Reinstall Mobile Substrate |
Step 2: After you find it, tap on and click Modify located at the top right corner.
Step 3: After clicking Modify, there will be Reinstall, Remove and Cancel. Choose Reinstall.
Step 4: Ok from here wake yourself up! Don't tap Confirm, instead choose Continue Queuing. This is to be done because it allows you to perform more than one re-installation later.
Step 5: Reinstall Ultrasn0w and get rid of No Signal issue on iPhone 3/3GS. Go to Cydia > Manage > Packages and search for ultrasn0w.
![]() |
| Install Latest Ultrasn0w from Cydia |
Step 6: Once Ultrasn0w is found, tap Modify > Reinstall > Confirm and wait for the reinstallation to complete.
Step 7: After the reinstallation of Mobile Substrate and Ultrasn0w, the No Signal issue and other crashing after the downgrade process should be fixed.
Congrats! You have fixed No Signal error on iPhone 3/3GS. Now you can enjoy! Leave your thoughts on how it worked out for you.

doesnt work for my setup / Still have No Service and Searching... I have a 3gs (OldBR) / 6.0.1 jailbroke with redsn0w, 6.15.00 reverted down to 05.13.04... samprefs running alongside and wildcard activated and working perfectly with itunes, ultrasn0w and mobile substrate re-installed over and over agiain... just no signal yet....
I performed the above steps but still have the "No Network" appearing. I have iphone 3gs, baseband 05.13.04 (downgrade from 06.15.00), ios 6. Only one notable thing, I can reboot without using redsnow or connecting to any computer.
oops, got it working now...

It did not work for my 3GS under 5.0.1 - it did not downgrade the baseband and I have no signal now (the fix does not work). It seems the phone does not even see my sim card now. (It does not ask to unlock it)
Good day, nothing poluchaetsya.Set probyval not catch many times already
uninstall ultrasn0w fixer and ultrasn0w 1.2.7, reboot, install ultrasn0w.
will this fix work on iPhone4 bb 1.59.00 "no service issue"?
Yes.
i forgot to mention iOS6.1 , will it work? is it safe to update with preserved baseband?
Yes, it's safe. Use ultrasn0w 1.2.8 - http://www.unlockboot.com/2013/02/ultrasn0w-128-unlock-ios-61-on-iphone-4.html
i have iphone 4s, it doesnt work with my tmobile sim card. i have 6.1 and 3.1.01 firmware. what should i do? =(
Unfortunately, it doesn't work on iPhone 3GS with baseband 6.15.00 on iOS 6.1.

it worked on my 3gs 6.1 bb 6.15.00. thank you so much. this is the simplest solution that really worked for me. I can't thank you enough.
Guysss...you all must know ultrasn0w 1.2.8 does not support iphone 3gs 06.15 ios 6.1 if your phone is NEW bootrom. Only support OLD bootrom!!!
Thank you.......very much bro..u did it ...All the people just do one thing when u are doing this process just uninstall repo.iparelhos and uninstall all ultrasnow fixer for 6.1..just see one thing that ur iphone3gs is in 6.15.00 baseband ...
i fucking love you dude :X
Dude you are a sweet heart :* loads of love for u :)
Hi Mohammed. does it mean that i can use the steps above even if im in 6.15.00 baseband? thanks
Yes you can do it.just follow the steps carefully..its ok bro...
hi john when u are following these steps u should uninstall ultrasnow fixers 6.XXX.after these u are done...
when u are on 05.13.04 baseband iphone3gs oldBR just do one thing..1.go to cydia,go to manage,add source "repo.iparelhos.com"after adding source just install ultrasnow fixer for 6.0.1 .after that just install ultrasnow then u are done!!!!!!!
Yes.... It works well. After two weeks of attempting other methods. Thank you very much.
not support in old bootrom
how'd you fix it? i have the same problem now..
can somebody please confirm me whether this worked on iPhone4 ios6.1 bb1.59.00 ?
I confirm that this works!!! It's a very long process but it does work for a updated 3GS on 6.1
***If you cant Activate phone after updating to 6.1, you'll first need to do the following:
- Hacktivate: with Redsnow 0.9.14b3 and "downgrade iPad Baseband like above," which will allow you to activate your iphone with a Tethered Jailbreak, (go into General>About and check to see if iphone has baseband: 05.14.04) if not then jailbreak again and downgrade again.
- Then restart Redsnow "must pick ISPW" and do a "Just Boot" then jailbreak until you get "Cydia" (you will have to this step if you cant get into Cydia, because it is tethered jailbreak),
- in Cydia: install "Evasi0n 6.1 Untether" (once installed properly the iphone will be untethered and no longer need Redsn0w.)
- in Cydia: install "Ultrasn0w". You should do a "Complete Update" in Cydia when ever available. Enjoy! You have now unlocked your iPhone to use sim card.
Finally. After days of jailbreaking and many wrong paths and restarts it has worked. Thanks
Uninstalling the ultrasnow fixers then reboot worked like a chark on my 3GS 05.13.04!
Sorry, I meant it worked like a charm*

-Jailbroken custom IPSW from sn0wbreeze 6.1, BB 5.13.04 (by doing iTunes restore)

-custom IPSW 4.1 (to preserve baseband)
-followed the instructions above to the letter, reinstalled (Q'd) mobile substrate then reinstalled ultrasn0w 1.2.8.

hi i have a IPhone 3GS with iOS 6.1 jailbroken by evasion but i have bb 05.16.08 and i have no signal on the phone any help please?
Thank you, sir. This did fix the problem I faced. I would strongly suggest adding the "remove fixers" step to the main guide, as I fear not everyone is going to be an avid of a comment reader. Cheers.
LOVE YOU TO BITS!
