Earlier today, we got the most awaited iPad Baseband Downgrade for iPhone 3GS/3GS for which people waited two years. Every year the hopes were used to rise for the iPad Baseband Downgrade. Whenever there was used to be a new release of Redsn0w, people sued to think that the iPad Baseband Downgrade would be included in that or they might announce the iPad Baseband Downgrade some time soon. Unfortunately, that dream of iPad baseband Downgrade became a dream at those times. The last year, @Sherif_Hashim, the baseband Hacker for iPhone showed a demo of the iPad Baseband Downgrade in progress. Still there wasn’t any progress told by the team.
After one year of the demos, the iPad Baseband Downgrade finally emerged for users who were waiting for the downgrade from ages. Many of the users lost their GPS by updating to iPad Baseband 6.15.00. There was no other way than updating to iPad Baseband 6.15.00 and to go for the Unlock.
Today, all of those who updated to iPad Baseband have got an opportunity to go back to the old baseband that is 5.13.02 and retain the official unlock with GPS back in their iPhone 3GS/3G. We know that no one can wait for the iPad Baseband Downgrade because it must be the happiest day of his or her life. Every one must be willing to downgrade their iPad Baseband to old one and must be looking for a perfect guide. So we have made a small and perfect guide for the users stuck on iPad Baseband to Downgrade it the easy way.
Note: This method will only work with iPad Baseband 6.15.00 and not for 5.14.xx+ basebands.
This guide can be used on MAC and Windows Both.
Step 1:
Download Redsn0w 0.9.14b1 for MAC/PC from our Software’s you need page. Don’t forget to run as admin mode in Windows Only.
Step 2:
Before going into Jailbreak press the “Extras->Select IPSW” button in redsn0w to tell it which firmware version you have installed (new-bootrom 3GS users can usually skip this step but it doesn’t hurt for them to do it too).
Open up Redns0w and hook up your iPhone 3GS/3G with your PC/MAC. Make sure that you got the iPad Baseband installed on your iPhone 3GS/3G. After opening Redsn0w, go into jailbreak Option.
To see for the iPad Baseband,Simply navigate to
Settings>General>About>Modem Firmware.
Step 3:
Here we forgot to mention one step and we are adding it right now.
You need to turn your iPhone OFF Manually before proceeding on with this step. This step is very important to avoid mount problems when the ramdisk is running!
Now put your iPhone into DFU mode and let Redsn0w recognize your Device’s iOS version.
Step 4:
Once the recognition is done, proceed next.
Step 5:
When you will proceed next, Redsn0w will show you several different options from Install Cydia to De-Activate.
You are only Interested in Downgrade iPad Baseband.
Step 6:
Only check that option of Downgrade iPad Baseband and Proceed next.
Step 7:
Cydia will do its work on your iDevice.
Once done, you will be back on to old baseband 5.13.02.
If you face any issue of “NO SIGNAL” on the old Baseband, then simply follow the guide here to solve it.
Once every thing is done according to the steps, you will successfully Downgrade iPad Baseband.

Hi,
I noticed in step 5 you used the 5.1.1 firmware. This step-by-step work with firmware 4.3.3?
Thank´s
yes. you can use any ipsw. actually we dont have any iphone with us. this will work with any ipsw fron ios 4.x.x-5.x.x
this doesnt work tried it for hours and still nothing ( iphone 3g 4.2.1)
It does not work. I have tried about 10 times on my phone but to no avail. My phone is 3gs with IOS=4.2.1 and BB=6.15. Serial number indicates that phone was manufactured 34 week of 2010.
I would be grateful for any tips.
contact me on daudi(at)techglued(dot)com @facebook-871135436:disqus and @scoot_eruk:disqus
@scoot_eruk:disqus @facebook-871135436:disqus really sorry for missing one step. I have added that step and see if it works fine with you people. I have edited step 2 and 3. Do follow that.
I only see slight change to step 3 and I think I have tried this before but not 100% sure. I will give it a go again tonight and let everyone know. Thanks
@scoot_eruk:disqus @facebook-871135436:disqus hey guys if this is still not working the iPad Baseband Downgrade method, then wait for the update of Redsn0w. Today @MuscleNerd Tweeted that he found out the solution for people facing this issue.
It worked like a charm for me, although lots of people are complaining on the Dev Team blog post that they’re now stuck with BB 6.15 because downgrade didn’t work for them, or they lost GPS functionnality even if their baseband shows 5.13.04. I must be lucky because it worked very well for me.
Just so you know:
iPhone 3GS
iOS 5.1.1
Baseband: 05.16.05, then iPad BB and now 05.13.04 after downgrade
Serial Number: 84945******
Model: MC149C
Maybe it worked perfectly for me because my iphone was manufactured on week 45 of 2009… I remember reading a warning notice by redsn0w about iphones 3GS manufactured after week 45 with fixed bootrom (the screen asks you to identifiy correctly the bootrom type by identifying the week – between week 40 and 45, it said “results may vary” or something).
Hope it can help…
Hope you guys can help me. I am running a 3gs v5.1.1 baseband 05.16.05, which is not unlockable. Also its the new bootrom. Can I just upgrade to ipad baseband and then downgrade it to 5.13.02? Is that safe? Cause when I try to upgrade it to ipad baseband it says that if its a new bootrom, the phone will become bricked..
Would the ipad downgrade fix this brick? or how does it work. hope u can help!
@disqus_S37WrBH5Hj:disqus We are always here to help any one with the issue.
Now in your case you need to make sure that what model are you using. If you are using iPhone 3GS 8 GB, then we won’t recommend you to go for this method. If you got a new Boot Rom and old 16 GB model, then we can say that you can go with this method. Still don’t apply this method.
U are awesome. I actually didn’t think anyone would help me. Anyway I am using a 32GB iPhone 3gs. The serial number is xx134 meaning it was made in 2011 the 34th month, right? They say that if the iPhone is made after week 27 or 28, upgrading the baseband would brick it…
to be honest i never checked the mode number and you dont see the model number. you see the manufacturing date. that can be seeing manually by a method or use Forecast tool by ih8sn0w. rest we can check out for the 3GS model and then update to ipad baseband if possible
The forecasttool says as following:
baseband: 05.16.05
bootloader: 6.4_M3S2
Model: MC134
Jailbreakable: NO
Unlockable: Upgrade to iPad BB
Can I rly trust that this program is safe to use, and its taken into account that the phone might get bricked?
The tool can be trusted and it is by ih8sn0w the hacker..

Thank you so much! I received my iphone from my sister last october 2011 and finally after all this time I have now been able to change the baseband and unlock my phone and actually use it! Goodbye android!
ahahahha.. You welcome

Thank you!
@Daudi I have followed all of these instructions and cannot get the baseband to downgrade, even following the steps it is still on 6.15.00
which ios version you are trying?
and use the latest redsn0w version that is 0.9.15b3.
I wasn’s using the latest redsn0w, it worked with the latest version. Thanks for your help.
But now i’m stuck on iOS 4.1, i cant get iOS 6.x.x to work, if i use Sn0wBreeze and iOS 6.1.2 i get iTunes error 3194, I’ve tried changing hosts and that doesn’t work, I’ve also tried a different PC and a mac.
i hope that u had saved the shsh blobs, because apple isnt signing ios 6.1.2 any more. and dont add any ip in the hosts file.
if u got the shsh blobs saved with u, then u can update using sn0wbreeze
I don’t have the blobs, is there any way I can get them?
Thanks a lot for your help
unfortunately. no. u can see in cydia if you got them saved. or else there is no way
No Cydia doesn’t have them :(
I followed the instructions here (http://www.techglued.com/unlock-iphone-3gs-baseband-5-16-08-ios-6-1-2-how-to/) and it doesn’t say I need to save 6.1.2 blobs, only 4.1 blobs
u dont need to have 4.1 blobs because apple is still signing them. mostly ios blobs are saved in cydia. you can save them via tinyumbrella and see
I give up.
Can i restore back to 4.1 and then update (via iTunes) to 6.1.3 to undo all of the baseband changing etc.?
dont give up that easily…
i can help u in seeing about what shsh blobs u got saved with you.
u can update and downgrade from 4.1 to 6.1.3 via itunes only if u got the old baseband. other wise use sn0wbreeze and do the updates
How do i see what shsh blobs I have?
download tinyumbrella and download it, then connect the iphone and press save shsh blobs to see the blobs
Thanks, I did that. I don’t have any shsh blobs saved.
