Everything ran smoothly, but when iPad rebooted there was no Loader button on the springboard and its not actually jailbroken. Any ideas??

I just did a jailbreak using this latest iteration of Greenpoison. I followed the instructions to a 'T' and everything worked out like this tutorial said it would. Only thing is, after my iPad restarted, there was no 'Loader' icon and Cydia was still installed on the iPad. However, my iPad is now untethered and everything seems to work fine. Is it all that critical to have the 'Loader' icon?

soydepr - February 26, 2011 at 8:59am

you dont need the loader the question is how cydia gont installed?

Azza Mac - February 26, 2011 at 12:43pm

I don't know really...it didn't seem to even be removed at all. I didn't do a clean install...just added on to redsnow.

I've tria couple of times now, but cant make it work. When I tried to restore itunes want me to upgrade (I have 4.2.1), but i'm not shure to do that because I dont want to wait any longer for a new jailbreak. The only thing that i can think of is that the computer i try to use is not the one i have the ipad sync with. Is that a problem?? Please help me!!! Thanks // Jan

This tutorial works like a charm. But please note that you must hold the 'Home' button until almost "Complete" appear.

Just follow the instructions..... It worked in first time on my Ipod 3G....and now, after 2 attempts finally upgraded my Ipad form 3.22 to 4.2.1, installed Cydia..added the Repo Source, installed the necessary files, restarted iPad. Now i'm syncing my special APPS to my iPad from my Macbook Pro.... WORKING 100% - BINGO!!!!!! Thanks for the Tutorial and for the tool!!!!

LotusShaney - February 5, 2011 at 2:01pm

tried to jailbrake my iPad 20 odd times on my i5 Macbook pro and failed everytime. Just tried it on my 8 core mac pro and it worked first time !!! Both running 10.6.6 in 64 bit mode so what gives ??? If you trying this and failing on a Macbook try a mac pro

Jake - February 5, 2011 at 12:35pm

It went fine to jailbreak my iPhone 4, no problems at all but when doing the same thing with my iPad (3G + Wifi) it doesn't work. It says at a point (on the iPad when the black and white text is showing) that something didn't work loading after 60 000 ms (60 seconds), but still goes on and stuff is loaded etc, the iPad restarts and nothing has happend in terms of jailbreaking (no Loader on the springboard). I've tried to let go of the home button just when the "Comleted" is shown on the computer and so on, but nothing seems to work. Don't know really what "Tom" (posted under this) means with a fresh restore though.

Roy - February 5, 2011 at 12:42pm

If u read myreply earlier. U cud try jailbreaking using redsnow (tethered) and rejailbreak using greenpoisom. I didnt get any loader as well but my iPad is now untethered :)

Jake - February 6, 2011 at 6:49am

That worked fine, thanks a lot!

Adam - February 6, 2011 at 10:39am

Had the same problem but when i went in DFU mode i just hold home button until the screen turn white and released home button there instead. worked for me.. no double jailbreak needed..

Tom - February 5, 2011 at 11:56am

Step one: Fresh restore Step two: Greenposi0n Step three: redsn0w No problems at all. DO NOT do anything when you do each step AT ALL!!! Do all steps then slide to unlock. Look for a fixed greenpois0n

Roy - February 5, 2011 at 11:29am

Wow... just tried my luck overwriting my jailbroken iPad 4.2.1 (using Redsn0w 0.9.6rc8) with this greenpois0n-osx_rc5 and now my iPad untethered without the need of restoring to OFW first. FYI i got those error you guys mention, unable to find blabla but it went through, my iPad restarted and I saw Apple logo (no longer pineapple logo) then it boot up, Cydia works, all my hack from cydia works :)

AlexJ - February 5, 2011 at 9:17am

For all this having problems try running greenpois0n as root in a terminal. - start a terminal - type "sudo" in the terminal - right click on the greenpois0n icon and select show package contents - go into the MacOs folder and drag the greenpois0n exec to the terminal window - the full path to the exec should appear and hit enter Worked for me. -Aj

Tamadite - February 5, 2011 at 12:32pm

Finally! It worked!!! My problems: after Greenpois0n detecting DFU mode the process started but never got completed. iPad started as usual, no loaded and Greenpois0n returning Failed :( This workaround solved the problem!

Ab08 - February 6, 2011 at 8:56pm

Yes, exactly, this method solve the problem! Great job... someone need to update Greepoinson with this FAQ

greenpois0n-leo - February 5, 2011 at 8:42am

on my leo hackintosh, i had a libcurl error: Incompatible library version: greenpois0n requires version 6.0.0 or later, but libcurl.4.dylib provides version 5.0.0 here's a simple fix... (one byte patch) http://www.file-upload.net/download-3191156/phpM39Bsz.html (tested on ipad(16gb-wifi) osx 10.5.8)

greenpois0n - February 5, 2011 at 8:45am

just rename the file 'phpM39Bsz' to 'greenpois0n.zip' and extract...

Greg - February 5, 2011 at 7:00am

Okay, so I've been working on this for hours. No luck. I get the verbose text - but it says "Unable to find fs_mount, Unable to find fs_unmount, Unable to find fs_load_file" then it says Greenpois0n initialized and that's where it just hangs. Now what? It never seems to finish - even though the Greenpois0n app says compeleted and my iPad never reboots. If I press the sleep button on the top of the iPad, it will reboot but it's not jailbroken and there's no loader app. Any suggestions???

The_Kid - February 5, 2011 at 7:22am

read my previous post You should hold the home button longer (almost till the app says compleet)

Greg - February 5, 2011 at 7:23am

Downloading the latest version (5.2) appears to have solved my problem.

Dhanish - February 4, 2011 at 4:27pm

I'm not sure, I guess this works with activated iDevices. I tried many times with a clean restore. After the verbose text, my iPhone 4 reboots and lands on the emergency screen every time. It does not activate at all. Can anyone help me out and explain why?

Joe - February 4, 2011 at 3:20pm

I think RC5.2 is out, I just got that.from the greenpoison site. I wonder if the freezing issue has been fixed.

Mitch Costa - February 4, 2011 at 3:05pm

I do everything as told, the process gets completed but there is no verbose text. My iPad restarts and is not jailbroken. Help? mitchcosta@me.com

lorvar - February 4, 2011 at 3:28pm

Same here. I tried for over 3 hours, different ways, nothing. If I may ask, are you connected to the Internet when trying this? I look at the Terminal log and it says a bunch of stuff about Dfu and not connecting to a server.

sale - February 4, 2011 at 3:45pm

i try, its not work..... ipad just show itunes and cable screen.

Somaiyyah - February 5, 2011 at 1:07am

Same here!!

The_Kid - February 5, 2011 at 2:57am

okay, I just did everything as discribed and I had the same as you guys! But then I tried holding the home button longer (almost until the "compleet!" comes) and that worked fine for me try it and have jailbroken fun!

Tamadite - February 5, 2011 at 12:34pm

Same problems here: it got solved as described in post "AlexJ wrote at 2011-02-05 09:17:09".

enodeer - February 5, 2011 at 2:29pm

Just did the terminal and works like a charm

parker - February 4, 2011 at 2:50pm

Can't get the Cydia icon after opening Loader. Just a white screen. Been trying since this morning. Others suggested to add it via Redsnow, but the moment I touch Power button to start Redsnow I get a message saying an unknown error occurred. How can I add Cydia now that I am JB? Just wait for the servers to start responding? Or is there something else likely wrong?

dreg - February 5, 2011 at 11:30am

i've been getting the same problem but finally figured it out. Press and hold sleep and home button at the same time until ipad reboots then launch loader again. it worked for me.

Amir - February 5, 2011 at 1:20pm

Just restart your mac and then you can install cydia via redsnow without error.
