How to fix some mysterious problems.

Previously running tethered jailbrake that was installed with redsn0w.

Attempting jailbreak using greenpois0n rc5. The green "Loader" icon is present, but when the Loader is run, nothing happens. I am able to connect to the local WiFi network and can browser to Google, etc.

If anyone can tell me what am I missing to get Cydia configured properly, I'd appreciate it.

If you need more diagnostic information, let me know.

If your device was previously jailbroken with redsn0w there is NO need to use Loader at all. Cydia should still be there if you didn't restore before using GreenPois0n. If you did restore though my advice would be running redsn0w and ticking 'Install Cydia' ONLY. This will install Cydia but retain your tethered GreenPois0n jailbreak.

Hope this helps!

Thanks! Gosh, I didn't know I could have "upgraded" to a non-tethered JB from Cydia. How would that have worked? (of course, now I have shot myself in the toe and need to fall back to a factory refresh.)

I have 29gb of data on my iPad. I was previously on redsnow tethered with 4.2.1 Yesterday I simply plugged in my iPad and ran greenpois0n over redsnow without any issues what so ever. All of my data stayed on it. I "didn't " sync or back up with iTunes before running gp rc5.

It would have worked exactly as JRFuller says. You don't really notice anything different, except that you have an animated boot logo and can GASP turn it off and on without a computer! Also, you'd probably want to delete Loader, since it would be useless in that scenario

After installing Cydelete to get rid of loader. But your (JRFuller) the first that I have seen where you got GP tethered to work with GP over tops of it. All other sources I have read have been with the ipad you had to redo the os and start over with GP. Great information to know. Thanks for posting that eh :)

Tried a full restore using iTunes from last pre-greenpois0n sync. Did not work.

Unless anyone has any ideas, it seems refsn0w --> pois0n has unexpected consequnces. Short of a full factory reset, any other suggestions?

For the ipad, I believe you have to do a full iOS restore, not just restore the software on it. Redo your 4.2.1 and rejailbreak it.

Good Luck! :)

Thanks for the idea: Tried that first, did not work. It dropped 'Loader' on the iPad, but running the loader app did not do anything. I then tried to restore to the last sync'd backup as described above.

Ok once you have loader re run rednow again and choose cydia it should install

If you have the loader on the iPad try rebooting the iPad heard that it helps...

I really appreciate everyone's comments -- especially those that got it to work successfully.

I reset the iPad to factory default software via iTunes, ran greenpois0n successfully, rebooted the iPad, made sure I had a good WiFi connection and ran loader to install cydia. I have to run the loader app a few times before I got cydia installed. I am running cydia now and anticipate no further problems.

... untethered at last ... Thanks!

I dont know 100% sure as I dont have an ipad in front of me to try it. Far as I have read and seen, for the ipad specifically, you have to run GP first. if you run redsnow, you have to restore back to 4.2.1 fresh and start over. Iphones and ipods are differnt. Ipads however you have to run GP first on a new 4.2.1 non jb'd ios. THEN if you dont get the loader you can run redsnow and load cydia that way. Again, its from what I read and seen.

Good Luck!
