    GOOD NEWS!!!!

    The first five of my REFURB serial: 5K916
    Bootloader 05.08

    Now I'm not sure if STEALTH remembers but I bought my iPhone in April '09, with BootLoader 6.04, then to make matters worse I installed 3.0 beta 4, and that ran my Baseband up to 4.24something. That killed my TurboSim and had me stuck to AT&T. Luckily my ringer switch broke so I had to take the phone into the Apple store and they swapped me out to this wonderful UNLOCKABLE refurb.

    DISCLAIMER: Now I am in no way saying for you to break your ringer switch to get a refurb if you upgraded to the BETA and/or your BaseBand cannot be downgraded, cause the refurb you get may be in the same situation. I'm Just telling what happend to me. BUT, if your ringer switch just so happens to break after you find yourself in a cannot downgrade or unlock situation, you SHOULD go get your phone checked (swapped) out.

    they might give you a refurb, think about it... apple is trying to get rid of their stock for the new iphone launch???

    but then again they might not... you give your iphone and they give you a refurb , so they are still stuck with a iphone except its broken?

    but i say its still worth giving a shot (as long as your ringer button is broken)



    iPhone? ... No?... MYphone!!!

    Some of the refurbs have BL5.8 but there is no guarantee.
    Has anyone had a refurb with a higher BL?

  6. #105
    Yes I just sent mine in through the mail and had it replaced and it had BL 5.9 . The first 5 of my serial are 5k916 so I guess the best bet is to go to the apple store and get it exchanged and not mailing it in to get a good shot at Bl 5.8 .

    Red face Downgrading the FW from 3.0B5 to pwnd 2.2.1 iphone 3g
    hello, i have an iphone 3g and it has 3.o beta 5 and i tried to downgrade from dfu mode into 2.2.1, and when it finishes restoring the software, and starts restoring the firmwarew, it posts an error message (1600) or something like that, and my phone gets stuck into recovery mode. i have tried a pwned an unpwned firmware 2.2.1 to do so, and still, i have no luck.i have a windows vista ultimate x64 and itunes 8.2. i also have bootloader version 5.08. plz help!

  8. #107
    Ouch, so I am assuming that if it's at 6.02 on 2.30 and 2.2, then it will be quite a while before these can be unlocked?

    That's the first case I've seen confirmed of a refurb having 5.9 and it has the same 5k as the first two digits and we've seen later ones with 5.8. Thanks for the info.

    There is another thread that explains how to downgrade, or maybe someone here will tell you waht your problem is, sorry, not sure myself, but once you've downgraded to 2.21 you will be able to downgrade your BB as well

    You might as well upograde to 2.21 again as you can't downgrade your BB, hopefully there will be a solution once FW 3.0 is released, in the mean time a PiggyBack SIM might help.

    but will they CHECK to see if you're a valid ATT user? If so, what if i give my ATT friend to bring it in, will they VERIFY that phone is tied to his account?
    haha

    because my RINGER button is a little wobbly too.

I am going to give this a try again because this first time it didn't work. By the way if anyone tries this make sure you keep the connection going because once you disconnect your iphone is no good unless you restore (it will not function). I don't really care about my iphone that's why i am determined to try all these crazy ideas of mine.
    * StealthBravo I think my hard work and dedication of doing research might be paying off. thanks for the help last night.

    IMPORTANT


    I think this might solve a lot of people's problems with Firmware 3.0 and Modem Firmware: 04.26.08. This guy is from China and has got it to work. I will order it soon and check to see if it works myself and if it does I will inform you guys where to get it.

    if you don't have a bootloader that is 5.8 you cannot downgrade. your only option is to get a rebel sim from eBay. Do not upgrade to firmware 3.0 if you wish to use your phone on T-Mobileit wiil change your baseband to 04.26.08.

    Buy it here:

    Apple Iphone 3G 2.2.1 FW Rebel Turbo sim Unlock 2.30.03 - eBay (item 260395568964 end time May-17-09 20:57:17 PDT)

    nother one shouting? Pity you are shouting something that isn't true.
    I use my iPhone on T-mobile 3G as to lots of people in Europe.
    [Edit] I see you've changed your post to say not in the US but as the OP was in London (UK) it is possible for his friend.

    And you're still shouting [/Edit

    from what i have seen,
    the refurbs i have come across have no rhyme or reason to the serials other than the 5k at the beginning.

    the third fourth and fifth do not follow a sequence that is applicable to the BL

    meaning,

    5K001-5K100= 5.8BL
    5K101-5K500= 5.9BL
    etc.

    this isnt the case.

    it seems that IF the phone being refurbished has a perfectly good logicboard/commboard (wherever the BL lives) then it is left alone, retaining the 5.8BL but is assigned the next sequential refurb serial.

    IF however the logic/comm is fried, THAT is replaced with new parts.
    given the next serial available and so on.
    the oldest parts are used first,
    using up the 5.8BL's
    they move on to the 5.9's.

    expect to see refurbs with 6.02 soon.

  22. #120
    The 3rd 4th and 5th digits, I believe are the same as a normal s/n - IE the date (year and week number) the device was 'made' - in this case, I believe, refurbished.
    The BL is just the original BL of the device being refurbished so could be anything depending on what devices they have had returned.

    That's my theory so far, but not enough evidence yet to be sure.
