    Removing the metal case is the biggest pain EVER! I have probably removed 30+ metal cases and I always have stress marks in them, it's impossible to do it. I have about 50 ipod opener tools sitting here, no matter what, as soon as I try to open the metal using them, the end of the tools just snap right off! Anyone have an easier way to do it without damaging it? If so, let me know!!

    Quick update on my progress. I managed to get the back cover off using just a card, an Esso Extra membership card to be exact. I just jammed it in and ran it all the way to the top of the phone.

    I did end up with stress marks part of the way up the phone, and the sides kind of stick out on it now that it's all put back together. I haven't attempted the bootloader downgrade just yet, I just wanted to find out how difficult it would be to open this thing up first. It seems like doing it without stress marks is going to be hard. The backing is very soft metal, the slightest pull on it will create some marks. We need something that will get under the backing in order to release the clips, but wont pull outward too much. I would assume the iPod removal tool would work find, but I have yet to try it.

    Let's keep sharing out stories here, we may be able to find out a nice fool proof process. Anyone try the guitar picks? How'd that go?

    dpmpc, i am wondering wether to try it or not... Does it involve a high level of electronic knowledge? I don't know how to do the needles thing, how much cables from one to another...
    No, not realy, as long as you have a calm hand and a reasonable thin soldering iron, you don't need to be a electronic crack. I scratched the tespoint and soldered a small wire to it an an other to the marked resistor, this wasn't too hard...

    I'm on the exact same situation, after running ienew over ssh I didn't get any output from it and the WiFi connection was dropped, after that I couldn't reestablish it. I tried restoring the phone with both 1.1.1 and 1.1.2 (the latter took forever) and get the 'Repair Needed' message, basically I'm stuck with a brick now. I'm using iTunes 7.5 on Leopard. What iTunes version did you use to make the 1.1.2 restore?
    ok, the same miste I made. Did you run iunew before you restored back to 1.1.1 (or 1.1.2)? And this produced no error-message? The restore to 1.1.2 took a very long time for me (~10 minutes), but after finishing Itunes said everything is restored (no errormessage) and the phone was working again. If you didn't run iunew, then you have to do so: AFAIK you can use ibricker on a 1.0.2 firmware to activate and upload files without wifi (dont't know realy, never used ibricker).

    I used Itunes 7.5 on Leopard to restore the iPhone back to 1.1.2. And I didn't downgrade the phone to 1.1.1 before I started, I used the preinstalled 1.1.2...

    i learned Electronic when i'm 16 years old, now i'm 28, working now in TV as graphic designer and no relation on electronic for about 8 years - something forget, but something not
    So the question is:
    "if the testpoints are on the Bootloader chip - theoreticly we can connect these testpoints in software way, just need to find code and put all together"
    why i'm say that? i remember in skool we doing that, but don't ask me to do it again, because 8 years make me rusty
    but some dude can do it - if this boot chip allow this

    I ran ienew from downgraded 1.1.1. After that no output appeared on the ssh session screen and the WiFi connection was dropped a few minutes later. I had no WiFi then, I could get to the home screen, open applications, etc. but no WiFi. So I restarted the phone just to get into the 'repair needed' situation. I tried restoring to 1.1.2, it took forever with no luck (got an error in the end of the process), the phone got stuck into recovery mode. I kicked out of it with Independence, it was then on 1.1.2 but still with the 'repair needed' and no phone/wifi functions. I downgraded to 1.1.1 again, upgraded to 1.1.2 (done that like 4 to 5 times already). Always with the same result. Only thing I haven't been able to do is to downgrade to 1.0.2 - I keep getting 'unknown error (1)'. I tried uploading the 1.0.2 WTF file on an old DP PowerMac G4 I have with Tiger using iPhuc, after that the phone would accept the 1.0.2 ipswf but got stuck on 'waiting for iphone'.

    I'm now restoring to 1.1.2 again, to see if I have any luck.

    Regards and good luck.

    I'm having the same problem as a few people on here: I ran the ienew command and lost wifi, and didn't have MobileTerminal installed. So I had no choice but to reboot the phone at which point wifi ceased to work and the repair message started popping up.

    So I saw one post mentioning restoring back to 1.1.1, then up to 1.1.2 -- I followed this procedure and still evidently had no baseband. When I restored 1.1.1 the error was 1011, and to 1.1.2 the error was 1002, and, like others have mentioned, this was an extremely slow restore. On neither firmware could I dial any numbers, and both were extremely slow to respond.

    Since then, I've followed geohot's advice and downgraded to 1.0.2. I then used iBrickr to jailbreak and install PXL, and Pacay Carnaval or whatever it's called to activate the phone. I was still receiving the 'phone requires repair' error message and the phone was very slow to respond.

    I installed MobileTerminal and copied the contents of the pack posted on geohot's blog to /usr/bin. I set all binary files to +x.

    iunew kept giving me a bus error -- I realised I did not have the testcode.bb or nor file. I found an old iPhone unlock pack containing these files that I had lying around, and uploaded then. I was still getting a bus error, but after chmodding all files to 775 I finally got to the point where iunew would ask me to connect the testpoint.

    After connecting the testpoint, I got to the point where you are asked to type a character and press return - then the 'Downloading modified nor...' which I left for an hour with no further progress.

    I had tried rerunning ienew but kept getting 'Could not write' or something similar.
    I am now attempting to update the phone to 1.1.2 again to see if the baseband is restored.

    Is there anything that I am doing wrong? I have noticed geohot's blog mentions finding an old nor dump and writing a new file with the first 0x20000 bytes which I didn't do... how is this achieved?

    Should I create this file and then attempt to downgrade to 1.0.2 and run through the procedure as I did before?

    Thanks in advance for any potential help.
