Error 2001

[cheesedoodle]

Trying to jailbreak with 2.1 and everything goes fine until:

In Recovery mode, I option-click Restore, choose custom restore file, it unpacks then begins to prepare iPhone. At this point my iPhone screen turns from black to white and iTunes generates a 2001 error. Unplug phone, reboots, un-jailbroken...

iTunes 8
2.1 firmware (upgraded from my original 2.0.2)
PwnageTool 2.1

I've tried both my 2.1 file and a downloaded one. Acts the same.

Any ideas?

kill itunes helper.. restart and try again..

I am having the same problem. I killed iTunes helper using Activity monitor and restarted iTunes (making sure that iTunes helper didn't restart in A.M.) I tried again to install the custom firmware and I am still getting the 2001 error. Any suggestions?

[cheesedoodle]

Actually, I killed helper, tried again and now get error 1600...

I seem to be going back in time...

[Phoenix29]

how did you kill helper

now I am getting the 1600 error as well

[cheesedoodle]

"Applications/Utilities/Activity Monitor/iTunesHelper"----Quit Process

Did your suggestion and still getting 2001 error.

Use the Pwnage tool again and select no when it asks if the device has been pwned before. This will put the phone in deep restore and then choose your custom firmware. It worked for me

Pretended that I had never pwned before...still no go.

I had pwned earlier (2.0.2) and everything was peachy, saw the 2.1 firmware update so restored to ORIGINAL (everything was fine...) then pwned with 2.1...that's when the problems began.

I fixed my 2001 and 1600 issues by restoring to the OEM 2.1 from iTunes, then pwning it after it was done.

I've turned off iTunesHelper, removed it from iTunes, and then deleted it. Rebooted Mac. Used Pwnage Tool 2.1 on OEM FW 2.1. I too get the dreaded 2001 error, over and over. I'm running OS 10.5.5. Any chance OS is the problem here?

One other piece of info. When I DFUed into iTunes, I initially got the following message: "An iPod has been detected, but it could not be identified properly. Please disconnect and reconnect the iPod, then try again. An unknown error occurred (2001)." I took that as a bad sign, and it was.

I had the same problem and what you have to do is kill pwnage and then restore using itunes and your custom firmware.

Hope this helps

Cheers

Tonight I discovered I hadn't upgraded my old backup Mac. Hurray for procrastination! Here's what I found:

1. Mac OS 10.4.11
2. iTunes 7.7.1 (I did not turn off iTunesHelper.app)
3. iPhone Firmware 2.1 (from iClarified - iPhone - Where To Download iPhone Firmware Files From)
4. Pwnage Tool 2.0.1

The pwning went just as it has in the past, with the exception that iTunes kept throwing up warnings (ha!) about not being able to install FW 2.1 unless I upgraded to iTunes 8.0. Everytime that message popped up, I dismissed it by hitting the OK button, which for me at least did not trigger an attempt to upgrade iTunes.

When I was finished, I was back in business, even though iTunes didn't recognize my iPhone. I bet it will on my main computer with iTunes 8, but after 3 days of frustration, I'm content to use the phone without syncing for awhile. By the way, Pwnage Tool 2.0.2 should be released by Friday. My guess is it will defeat the problem of iTunes refusing to recognize a previously pwned iPhone.

A final note. The process activated and unlocked my iPhone and Cydia and Installer are back.

This worked for me ~>> http://www.modmyi.com/forums/pwnage/...-1600-yay.html

OK,

I was able to get by these errors (all of them actually) on a mac.

1) Start itunes -- if you are stuck in psudo DFU Mode pr not
2) Run pwnage and build an ipsw
3) When you get to the "does your phone have the pinapple logo" question say no.
4) Attempt to recover (option click on restore) and select the new fimware you just created.
5) It will fail! but suddenly pwnage will be able to get you into the correct dfu mode again (it took me three times to get the timing, keep trying)
6) Now option-click-restore again.
7) You have unbricked your iphone and upgraded! Congrats

bump! i'm getting the 2001 error, i can't get it to work.

running osx 10.5.5, itunes 8.0.1

[lillstar12]

This worked for me after 3 days of trying to pwn my new 2.2 on 10.5.6 follow the instructions from here Re-enable DFU mode in Mac OS X 10.5.6 & MacBooks (unibody 2008) - Hackint0sh this only works for macs though .

I believe only macs have the problem though .

Actually i had the problem trying many times on my new macbook pro then i went to the old one, which apparently has the exact same version of PWNAGE tool and it worked perfectly

so i researched it more and there's talk about it being a problem with the new generation macbooks 2008.. so if it helps try it on another computer... i guess that has to do with system updates as well then... leopard thing or sth...

However... it worked only once on someone's mobile but i think thats cuz it was already pwned to 2.1 before...

Connecting through USB HUB helped under 10.6.6 - funny trick but it worked - it was posted somewhere here in forums. error 2001 thread
