try rebuilding the ipsw... that usually happens with me and if i rebuild the ipsw it works fine :) and i also had the 1 bar when i still was on 4.3 gm . i guess it only occurs if you have the 1.59 baseband still? the multi touch gestures work fine
 
when i do that itunes just says....preparing ipad for restore and sits there forever until i get error 1601. really weird
 
I've tried again several times including restoring back to 4.2.1, 4.3 GM, rebuilding the Custom .ipsw multiple times, etc. Can't get past error 1600. Oh well.

Can you guys show me how you are trying to achieve the jailbreak in a time line fashion...

Example:

Restore Stock 4.2.1 => Update 4.3.0 => JB'd 4.3.0 [Failed] => Restore 4.2.1 => JB'd 4.3.0 Success

This way I'll see what went wrong.

It's possible you have a slightly corrupt ipsw (not the custom one). Even Apple has given me bad firmware downloads at times. Try re-downloing it.

Also, try rebooting your computer. That's fixed my jailbreaking issues when it refused to work.

I'll try again tonight at home. It's possible my work LAN is the problem as I've had issues here before though only with OEM .ipsw upgrades, not JBing.

To answer earlier questions, I did re-download both 4.2.1 and 4.3 GM. I first restored to 4.2.1 baseline then did a JB on that to confirm that still worked (used GP for that) then reinstalled 4.2.1 baseline, upgraded to 4.3 GM, and tried the pwnage approach again including building yet another Custom .ipsw from a freshly downloaded 4.3 baseline. I've also tried rebooting and using different USB cable.

The exact sequence of errors is that the first attempt to Restore using the Custom .ipsw created by pwnage aborts with Unexpected Error (1). All subsequent attempts to restore abort with (1600).

I'll report back after trying at home tonight.

UPDATE - No joy. Tried at home tonight with same result. Error 1600. Fall back to 4.3 GM and wait.

If you've never used it before in the previous betas then you've never installed libUSB or whatever it's called.

When you're running the tethered boot patch set it up like this instead of how they show you in the video:

/Users/tr/Desktop/tetheredboot-1 -i /Users/tr/Desktop/iBSS.n90ap.RELEASE.dfu -k /Users/tr/Desktop/kernelcache.release.n90

I was stuck like you for hours and hours before I found this solution, spread the word.

APUNKROCKMONK YOU ARE (and excuse my french) A FU**ING GENIUS!!!! I was about to totally give up this until I saw your post! THANKS A BUNCH!!!
 
I read the final version of 4.3 is the same as the GM, does this mean the five finger gestures are still hidden within?
 
I'm currently running a jailbroken iPhone 4 on iOS 4.3 GM. Cydia works and I currently have the following cydia apps installed with no issues:

Activator 1.5.4~beta2
Cyntact 1.4.1-1
Five Icon Dock 0.9.3202-1
iBlacklist 4.2-1
iFile 1.4.2-1
LibWeather 1.1.0.0
Lockinfo 3.0.1.0
Multifl0w 2.1.3
Popup Blocker 1.5.1.0
Recent/CallLog Delete 1.5.1
SBSettings 3.2.1
SpringFlash 1.3.1
TetherMe 2.0-59 (Personal Hotspot tethering works)
3G Unrestrictor 2.3.1-1

Also, pre-jailbroken IPSW's can be downloaded at:

To boot tethered, just write a batch file with tetheredboot.exe, iBSS, and kernel cache commands so the process is faster. Not really a pain at all (other than having to be tethered).

I managed to get Cydia on the iPad but was unable to boot tethered. The exploit passes properly but the iPad does not boot. Any ideas?

NVM. Got it to work! Thanks to a post on this thread.

Any more thoughts on my 1600 error?
