thanks a lot
i don't have 3.1.2 SSH because, i planned to do it after the reboot.... i didn't knew that this could happen.
I think i will use redsnow in another ocassion, but know, i will have to restore to 3.1.3 and wait a new jailbreak.
Thanks again

SHSH for 3.1.2 must have been requested before 4th Feb. Waiting till after the next restart was not going to help with that.

I would not advise restoring to 3.1.3 right now. Yes redsn0w is generally a better jailbreak.

This is all getting way off topic.

Greetings to All,

In my situation, my 3G gets stuck on a boot loop between the (low) battery icon & Apple icon with Blackra1n (RC3) running in Windows XP & iTunes closed.

Qs: Should I continue to leave Blackra1n running with the iphone plugged in even though it seems like the PC does not recognized the USB connection?

2) If successful (getting to the Home Screen), should I run the permanent fix: Use Cydia to add the official repository and upgrade blacksn0w to RC2 Final?

Though I do not post very often, I get all my 3G support through your website. Thank you.

Kenneth

Yep. As mentioned, the phone does not need to be recognized initially. So long as the phone discharges, it will charge from the USB cable (unless there are hardware issues or other issues), and it should kickstart the phone after it dies and re-charges.

I've left blackra1n running day and night for about 4 days. With about 2 or 3 interruptions only and the cycle continues. I can't believe this has worked for other people. I was just about to give up and install 3.1.3 so that I could at least have an ipod touch instead of a brick.

Is there something in specific that the computer should have or not have ? Something that should be done ? I don't understand what I could be doing wrong.

I have an iPhone 3gs, 3.1.2 jailbroken and unlocked, new bootroom.

Any comment or advice would be greatly appreciated.

Likewise, it did not work for me. I left it over night. This morning, the low battery icon reappeared along with the Apple icon. I am tempted to restore with iTunes but do not want to give up hope yet. Any more suggestion..? Thanks.

The method describe in post #1 does not guarantee that your phone will boot. However, it is probably the only known way (up until now) to get the phone to boot once it got stuck in that loop.

Some people let it blackra1n run and after 20 times, the phone booted. Some left it for an hour, some left in for day(s). There is no magic "time" that we can speak of but generally the phone boots once the battery is drained.

My only advise is to be patience, disconnect the phone, power it off, walk away from it and try again another time. I hate to say it but i guess some luck is needed as well

ISSUE:
iPhone 3G/S gets stuck on a boot loop where the phone boots, shows the Apple logo (or GeoHot's face, depending on where you get the error), gives the Apple spinner, sits, then reboots, and repeats the process over and over. Alternately, the iPhone 3G/S gets stuck on a boot loop, shows the Apple Logo (or Geohot's face), gives the Apple spinner, and sits. This usually occurs on iPhone 3GS models with the latest bootrom, after a user has told the device to "Reset Network Settings" after WiFi connectivity has been lost. The problem can also occur if after the iPhone soft reboots after you have lost WiFi connectivity, for example, after an application install such as MobileSubstrate / SBSettings.

CAUSE:
This is caused by a race condition that exists on the iPhone 3G/S related to the WiFi implementation and is UNRELATED to the jailbreak and unlock itself -- this occurs on both jailbroken and unjailbroken phones as well as carrier-locked and software-unlocked phones. Admittedly, it occurs more with soft-unlocked devices, but this is because the unlock exacerbates the existing problem with the race condition -- not because the unlock is unstable or potentially dangerous (it's not!). Quite the contrary, the most updated unlock actually resolves the race condition -- which Apple's own software still has yet to resolve. That said, this issue CAN be fixed in several methods and the newest version of blacksn0w (RC2 Final) contains a fix that solves this problem permanently.

FIX:
If your phone is exhibiting the boot loop, there are a few things you will want to do to fix it to get everything going.

1) Download the latest version of blackra1n.
2) Plug the phone into your iPhone USB connector, plugged into a Windows machine running iTunes and blackra1n.
3) The phone will show as connected but will NOT charge. THIS IS EXPECTED BEHAVIOR.
4) Keep blackra1n open and keep the phone plugged in, and go do something for 8 to 12 to 16 hours. This is a VERY IMPORTANT STEP.
5) When you come back to your phone/PC, your phone should be at the home screen and charged and you should be good to go.

WHAT IS REALLY HAPPENING:
When the phone gets stuck in the reboot loop, it is unable to charge via the USB connector plugged into the PC because the iPhone doesn't get that far in the boot process before the race condition exhibits. The device gets far enough to mount the root filesystem and to provide filesystem access over USB, however. When you leave it plugged in and walk away, what you're really doing is allowing the iPhone to completely discharge its battery. When it does this, it will power off. Once it has powered off, it will begin charging via the USB cable. Once it has sufficient charge to power on, it will power on. During the power-on process, blackra1n will see the iPhone and will kickstart it.

PERMANENT FIX: (thanks for clarification, dtube!)
There are several options for a permanent fix, depending on the state of your phone after it reboots when the steps above have completed.

If, after completing the steps above, your iPhone reboots but is still unable to connect to WiFi, you will need to remove the blacksn0w unlock and re-apply with the latest version (RC2 Final). Removal instructions for blacksn0w depend on how you installed it -- if you used Cydia to install, you can just remove the package. If you used blackra1n to install, you would need to either SSH to the phone or connect it to your PC and use iFunBox/DiskAid/etc. to remove /usr/lib/blacksn0w.dylib and re-add the original com.apple.CommCenter.plist. Once you have removed blacksn0w, the phone should reboot properly, allowing you to install the latest version of blacksn0w (RC2 Final) from the official repository (cydia.pushfix.info).

If, after completing the steps above, your iPhone reboots and is able to connect to WiFi, you should immediately launch Cydia, add the official repository (cydia.pushfix.info) and upgrade blacksn0w to RC2 Final.

This should return your phone to 100% working (and unlocked!) status.

If anyone has any additions or corrections, post them in the comments below and I'll keep this updated.

Worked perfectly on my iPhone 3GS 3.1.2 old bootrom! Thanks man!

Mine is a 3GS 3.1.2 32GB with new bootrom (MC, 40+ serial number), no carrier lock as I'm from Singapore.

I did a reboot of the phone after installing and uninstalling some stuff from Cydia. When I used blackrain to start the phone again as usual it hanged at the geohot screen. It stays there for several minutes then reboots itself again into recovery mode. If blackrain is running, geohot's face appears again and it just goes in a cycle. I've been doing this for the past 3 hours already.

However, iTunes does not detect my phone as being in recovery. It is able to detect my phone intermittently when geohot's face is there. It will say "iTunes must check the Apple software update server to identify this device", which is normal when I use blackrain to start the phone. It does not detect my phone as being in recovery mode or ask if I want to restore my phone. I ever restored it before when it became an iPod for some reason, so I know it is different. Also, when iTunes is able to detect (it also can sync, just that my screen shows nothing but geohot's picture) my phone, I can also access the root folders with iPhone Folders and iPhone Explorer.

The whole thing keeps going in a cycle as long as iTunes and blackrain are open on my latop. My iPhone is not newly jailbreaked. It has been jailbreaked since last December and this is the first time this has happened. Prior to that I rebooted several times the past few days without any issue. WIFI was not on. I just installed SBSettings on my phone a few days ago. I was tinkering with iAcces4 before the soft reboot. And I realised Cydia, Winterboard & related apps crashed and wouldn't start, hence I rebooted the phone and I got stuck in this reboot loop.

Is this the same issue that is being posted here?

My battery was about 30+% before this happened. So I have to wait until the battery totally drains and see what happens after that?

I'm on Win XP and iTunes 9.0.2.25.

I'm almost desperate now and in no mood to do anything else....

I left the phone this time for a couple of hours and went out. Made sure to leave monitor running all the time under Properties.

When I came back, blackra1n had run about 7 or 8 times but hanged after that. My 3GS left in recovery mode screen. Opened Task Manager, blackra1n was not responding. Had to end process and tried blackra1n again. Still the same thing. Stuck at geohot's face.

I searched the net and tried redsn0w, iRecovery to no avail. No problems but no help either. Now trying to multi-blackra1n again. In 5th cycle of blackra1n now. I wonder if it will hang again...

There is still no concrete solution for this problem, is there?
