Important announcement for iPhone3Gs users on 06.15.00 baseband updating to iOS5

Along with the release of iOS5 compatible Ultrasn0w 1.2.4 yesterday, the iPhone-Dev team added a special note for iPhone3Gs users who have updated to the 06.15.00 iPad baseband or plan on doing so. Just like any other unlockers, 06.15.00 baseband users should NEVER update to a new firmware using a stock firmware. Even though the iPad baseband cannot be upgraded, trying to install a factory firmware may screw up the baseband.

If you have already tried updating to iOS5 stock firmware on your phone with 06.15.00 you will probably have to reinstall the iPad baseband. For those who updated with a custom iOS5 firmware, there is a special process you will need to do after restoring iOS5.

During the new setup screens you see when you start iOS5 for the first time, you’ll be asked about Location Services. Be sure to select “Disable Location Services” when asked! Later on in the setup, you’ll have the chance to turn on Location Services again when asked if you want to use “Find my iPhone”. It’s fine to turn it back on at that point, if that’s your desire (or you can always go in and enable it in Settings.app).

Also, some iPhone3GS users with the 06.15 baseband may have tried to install iOS5 using a stock IPSW (even though you should never ever try to use a stock IPSW if you’re an ultrasn0w unlocker). If you did try this, your baseband is probably in an inconsistent state, and you’ll need to reflash the 06.15 baseband again (using redsn0w). Be very careful if you use redsn0w to reflash the iPad baseband — don’t interrupt the process! And please avoid using stock IPSWs in the future Unlockers should never go near stock IPSWs.

Hey, i was dumb enough to update via the normal ios5, how can i reinstall the ipad baseband`?
- http://iphoneblogr.com JaeM1llz
  
  Same way you installed it the first time.
  - Dennis
    
    Yeah, but i need 4.2.1 for that or can i install the ipad bb with the new redsn0w as well?
    - http://iphoneblogr.com JaeM1llz
      
      No, you will need to do it the EXACT same way you did it before. I think you need redsn0w 0.9.6rc5 and a 4.2.1 IPSW file.
      - Dennis
        
        Hey, thanks for your reply. I tried it, but there were 2 errors:
        
        Mounting rootfs as read-only…
        ERROR!
        
        AppleBCMWLAN::handleOKitBusyWatchdogTimeout():Error, no successful firmware download after 60000 ms!! Giving up…

I have a 3GS with baseband of 06.15, i updates using iTunes to ios5 and jail broke and installed cysia using redsn0w. but won’t accept my sim card or activate via APPLE? I think i went wrong installing the apple update without using the redsn0w version. PLEASE HELP !!
- Nafousa
  
  I had the same problem as you when I installed ios5 via itune and jail-broken my iphone 3gs therefore, it wouldn’t recognized SIM card(Carrier). I had to repeat the same steps when I jail-broken it but this time I tick the second option on reds0nw for baseband then install ultrasn0w. it works fine now. I hope it works for you as well.
  - Ron
    
    dudeeeeeee. it worked for me. the only problem is you have to connect your phone to the computer and open redsnow for it to reboot. It is now a tethered jailbreak. sucks. but i am getting phone service now. finally. Thanks a lot. you are my hero.

      If you are on 5.0.1 there is an untethered jailbreak available with redsn0w 0.9.10b3.

I have an iphone 3Gs that I bought in Canada and it was unlocked there to bring to Portugal.
When it was upgraded to ios5 it simply froze! But with redn0w jailbreak I was able to make it work again. The BIG problem now is that it is not able to find a carrier not matter what I do And it doesn’t even ask for the SIM card, and I am not able change those settings.
My baseband is 06.15.00.

Please, can you help me fix it?
Sinean

Nafousa can u tell us clearly. I had the same problem. I can’t reinstall iPad baseband always error!

whats the bad having firmware 06.15.00 on 3GS ios5! and how to fix the dropping signals problems
John Hopkirk

I had the problem of where my dumb sister somehow managed to upgrade to iOS 5 on iPad baseband (didn’t think it was possible). It would not activate, iTunes kept saying ‘There is no sim in the iPhone’ and afterward her phone kept searching for reception and then displaying ‘No Service’.

If anyone has managed to update to iOS5 or above with 06.15.00 baseband, what you need to do is re-install the iPad baseband.

First, it’s probably best to downgrade to a custom IPSW of 4.1 via Sn0wbreeze 2.1. Once you’ve made this, get the phone into DFU mode and restore via iTunes to this newly made firmware.

Once it’s successfully complete you should be running 4.1 on baseband 06.15.00. You’ll then need to open up redsn0w_win_0.9.6b5.exe, select the original 4.1 IPSW (not the custom one) and tick the “install iPad baseband” option. Then follow the instructions and hopefully your phone will be fully working again.

Hope this helps, I know it worked for me and got my sisters phone working again.

This doesnt work for me?? it sais error in the end when all the letters comes up

  so meaning if I updated the baseband the my 3gs is already useless?

Hi, I was thinking loosing the IPAD BB may be a good thing since it causes, GPS and other problems. I have a 3GS 4.3.3 at the moment.

Is it possible to update to iOS 5, and once the IPAD BB is no longer there, can I get my phone officially unlocked? What Baseband will I have remaining after the official unlock?

  Once you’ve upgraded to the iPad baseband you are stuck there. There is no way to upgrade or downgrade it.

Hi mate, thanks for the info. I tried to restore my 3gs to the stock firmware, but it didn’t work. Then I created a custom ipsw with pwnagetool and restored and it worked partially. WIFI is unstable and I lose also my reception. So I guess I screwed the BB a bit. You said in this case we must reinstall the iPad baseband. Can you tell me how to create a custom ipsw with the iPad bb? Thanks for the info, cheers

Hi. I have an iPhone 3Gs which was already jailbroken before I got it. iOs 5.0.1. Then I didn’t know anything. i updated it to 5.1.1 then earlier I made the worst decision. I was having issues, so i restored it. Little did i know about the damage. SO i went thru the process for 2hrs in Redsnow and restoring the 5.1.1 iOS. So I can use everything except no service, and I have to download via cydia the ultrasnow app, but I just wanna ask, iOS 5.1.1 and baseband is 06.15.00. I know this is the worst decision ever. But what can I do? Whats the best thing I can do to fix this if ever the Ultrasnow wont work. I dont have a copy of any iOS except of 5.1.1. Should I downgrade and download a lower version of iOS? How can I do that? Details pls. Help please!
- JaeM1llz
  
  If you restored a factory firmware you corrupted the baseband, all you need to do is reinstall the iPad baseband and use the Ultrasn0w 5.1.1 fixer from the post on our homepage.

    Im no expert at this. This is actually my first time. But how can I reinstall the iPad baseband? And I read the latest post with UltraSnow 5.1.1, and I wasn’t able to get a hold of the previous basebands, coz I was just talking to a technician over the phone yesterday and he just somewhat assisted me. In awhile I’ll be going over to my friend’s house to use their wifi connection to download the UltraSnow via Cydia (like the technician said), but what if it doesn’t work? So i’ll dload rocky racoon 5.1.1 instead?

hi. i also have an iphone 3gs with ipad baseband on ios 5.0.1. My brother wanted to update to ios 5.1.1 but he did not know you need a custom ipsw to do so. Now the phone is stuck on the authorization screen saying there is no sim installed and it keeps searching. This would not be a problem if my lock button, (power button), was not broken, so i cant put it into dfu mode the normal way. If anyone knows a way to put the iphone into dfu mode with out buttons please share. thanks in advance.
