Hi guys, i finally decided to update to 4.2 and to JB my Ipad, everything seemed to be fine but once rebooted cydia keep crashing (after unthered reboot). Any idea about how to sort it out? txs

It does not sound as though you have correctly rebooted tethered to redsn0w. Describe exactly what you are doing when you reboot...

i actually follow the procedure, open redsnow, folllow instruction, put in in DFU, switch off, flag the right option, JB, reboot.... and nothing, cydia seems to be correctly installed but nothing....

i had big problems with 4.2.1 and cydia on a iphone 3g it wont install all pakages i dont know if the ipad is doing the same as my ipad is still on 3.2.2 firmware jailbroken untethered with limerain.

If you are sure you are doing it properly (you see a pineapple when the iPad boots correctly tethered, not the white apple logo, right?), then something serious is wrong. The easiest suggestion is to restore to a clean 4.2.1 and re-jailbreak. Starting afresh is a pain, but it should sort whatever problem prevented the jailbreak from working in the first place...

open redsnow, folllow instruction, flag the right option (install cydia 1st time - teathered JB 2nd}, following instructions [turn off] put in in DFU keep holding home button untill the 2nd waiting for reboot or ipad appears

My experience with the jailbreak is that sometimes it will work and sometimes it won't. I think the timing of the two buttons that are involved can be rather hit or miss. I have rebooted sometimes as many as three times to get the thing going. I used the exactly same sequence as outlined in the guidelines. Then, bingo--it works. There seems to be no rhyme nor reason. I would certainly go through the procedure a number of times before "starting over." Also if you do finally get the pineapple--be patient. It takes a while to respring. At first I thought it was hung when the pineapple appeared and did not seem to be "doing" anything. Give it time.

Hi Folks,
My apologies, in advance, for hijacking this thread. I am experiencing the exact same problem and thought I would avoid starting a new thread for it.

I've upgraded, successfully, to 4.2.1.
Applied redsnOw, and ended up with a "white" cydia icon that would not load.
After some reading, I applied redsnow again and selected "tethered reboot" instead of "install cydia".
This seemed to correct the "white icon" issue.
I successfully started cydia and entered myself as a "user".
It asked me to upgrade a bunch of files, which I did. It showed a successfull install and prompted me to reboot the ipad.
I did.....saw the pineapple logo, and it restarted successfully.
Since then, neither cydia or safari will run. Both crash immediately on selection.
I restored the whole o/s back to a clean 4.2.1 and reapplied the jailbreak.
Same results.
Any suggestions and/or thoughts are greatly appreciated!

Well, as long as you are seeing the pineapple and NOT the Apple logo when you reboot then it shoudl be jailbroken. You are definately running redsn0w EVERY time you reboot. It's not just the first time like a couple of people supposed...

Success! At least partially..... I reapplied the 4.2.1 install, twice more. Each time initiating the jb from scratch. On the third try, everything worked.
Then Cydia required 2 updates....each requiring multiple reboots.
The whole process didn't leave me feeling confident....as with previous jb's.

Now, a new issue has arisen. About 50% of my icons disappeared. I find reinstalling the
app restores the icon; and the program still has all the original settings
in it!
I haven't had a chance to do another sync with my computer.....perhaps that will help?
Or am I relegated to reinstalling everything?
Thank you, F4780y, your input is sincerely appreciated.
