      i got error "1013" , you said it should be ignored in your guide but the result of that is no firmware on your phone and you have to start from the beginning once again. so i guess i will have to use 2.2.1

      The guide had worked for ezio-xb who tried this on his iPhone 3G as mentioned in the post above.

      Don't you guys have better things to do than to screw with your phone constantly? I do. That is why I run with stock Apple firmware now. No more troubles. My phone always works as expected (without lag issues) when I want it. No more contant restoring, worrying about updates breaking stuff, crashes, slowness. Everything is gravy without jailbreak and I don't miss anything.

      Don't you have better things to do than criticize others for using THEIR phones the way THEY want? And since this is iPhone Hacks after all, I would've thought that this would be the sort of place for, you know, hacking the iPhone. Just a thought.

      you dont listen the firmware is on there its just not activating follow the steps and you will be ok if you perform half the steps expect an half ass job!!!

      its jan 30 and i woke up at 5am with m y iphone 3g going NUTS it kept vibrating two times rough every so many seconds or minutes..
      I awoke to find only emergecy call available i was beyond confused thinking i hit it sleeping.. i tryed to open it with the slider and now it said to restore to itunes so i pluged it in ( i dont read these sites now that i read about the new update after researching what happened)

      Now i bought this unlocked with yellowsnow and my old 2g ( my savor for now) wasnt unlocked with yellow snow.

      backto the point were can i download the downgrade firmware? can someone make a video for everyone who has no idea how to go about unlocking it ( hence i never did it in the first place! but yellow snow did seem pretty stupid to me when i researched it)

      any news or updates when devo will crack it?

      Apple makes me so mad, I wanted more so i switched from blackberry curve at first i missed it but now ive grown to love the iphone.

      update i tryed to downgrade my firmware and i got after the ten minute process ..

      http://www.blogsdna.com/1838/download-yellowsn0w-to-unlock-iphone-3g-firmware-22-baseband-02280-2.htm


      i got this one error 1002
      any ideas?

    • via Wordpress

      Luckily I made it in Windows Vista! I downgraded my iPhone 3G from 2.2.1 following the above-mentioned steps, then I got the error 1013 and I ignored it.

      It comes to the most important part:-
      1. Disconnect the iPhone3G from iTunes when it comes across the error 1013. (Actually the firmware 2.2 is already successfully installed)
      2. Launch Quickpwn 2.2-1, at this time, quickpwn will pop up a window telling you to hold down both of the power & home buttons for 15 seconds then release the home button but keep holding the power button for another 2 seconds to re-activate your iPhone3G.
      3. Then you will see a white apple as usual and the iPhone 3G is now re-activating.
      4. You can see a normal screen with those lovely icons and your service back to normal.
      5. Jailbreak it using the ready launched Quickpwn tool.

      I'm now reinstalling everything from Cydia.

      Good luck to all of you:-)

      Hey jeffwg,

      Thanks for the tip!

      We have updated the post with your instructions for the benefit of other readers who might hit the same issue.

      Thanks again.

      With the new updated, THIS REALLY WORKS!! if u were stupid enuff to had updated your iphone, get back to 2.2 here. I was up all night tryna figure how to do this, **** what other sites say THIS IS THE ONLY WAY TO DOWNGRADE. Dat 2.2.1 sucked soo bad

    • JammerzzJammerzz Posts: 2

      The iphone 3G can be downgraded back to 2.2 but once you updated to 2.2.1 It won't allow any GSM network except ATnT..yellow snow doesnt work..network cannot be unlocked we have to wait for the dev team to unlock the baseband..until then it's an ipod touch which is sad...

    • via Wordpress

      Sorry about it! As you can see the baseband is already upgraded to 02.30 even though you downgrade your firmware from 2.2.1 to 2.2. So it means we can only jailbreak it without the ability to unlock it.

      hello dev team and a big thanks for the unlocking 3g slution which worked perfectly on my iphone 3g with 2.2 firmware ... but all that untill my _____ brother upgrade it to 2.2.1 and relock my phone again ... well i managed to downgrade it just like the instructions given by your team and i also jailbrake it with the error 1013 but i ignored it and worked just fine but cause my modem firmware stayed 02.30. i can not unlock it .... please dev team help me solving this problem asap... thank you in advance thank you very much

      Ok guys I did all the steps, I got error 1013 and then used quickpwn which put it back to 2.2 although the modem firmware didn't change, two things in my about first when using an ATT sim card the network was nul nul, I took that out went to my Gevey plus T-mobile I get a signal for like two sec. then back to no service which is no difference from after that stupid update to 2.2.1 ... I will try to downgrade to an earlier version and will keep you posted ...
      Ohh and I couldn't run the instructions on my macbook pro . thank God I still have a pc ;) but again there was no point cause it's not working as a phone ;(
      TIP :I have my IPhone 3g froze on me earlier and I tried a bunch of reset for it finally I decided to try quickpwn and it helped unfreezing it in dfu.

      For those of you having problems!!!

      You should FIRST figure out what your problem is!

      Are you one of the people that was using an unlocked iPhone with another carrier (like TMobile for example) and accidentally plugged in your iPhone to iTunes and installed the new 2.2.1 on your phone?

      If so, On your iphone, go to SETTINGS > GENERAL > ABOUT: now scroll down to "Version" and then scroll down to "Modem". Depending on what these numbers say - will depend on what your options are at this point.

      The problems lies not really too much with what the "Version" says - it is what the "Modem" says that is the biggest issue at this point.

      IF you are only interested in JAILBREAKING your iphone.... follow the instructions in this youtube video to DOWNGRADE from 2.2.1 back to 2.2. This will make it to where you can use your phone with ATT only but you can jailbreak it to put other fun stuff on your phone.

      IF you are interested in UNLOCKING your iphone - check to see what the version and modem read on your phone...

      IF version says "2.2" and modem DOES NOT say "02.30.03" then, go to the following website and do everything they tell you to do.
      http://blog.iphone-dev.org/

      however, IF you are interested in UNLOCKING your iphone and the version says "2.2.1" and the modem says "02.30.03" YOU WILL NOT BE ABLE TO UNLOCK YOUR PHONE AT THIS TIME.

      from what I have read today online - there are teams working on hacking it - but until they do - you have a nice itouch to play with :)

      I know it SUCKS!!! I myself am dealing with this issue. I have been on the computer for HOURS trying to make my fun little phone work. :(

      Hope this has helped. I just tried to compile everything I learned today in one spot.

      Use the youtube video: http://www.youtube.com/watch?v=xO1jiPE9nnY
