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....
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...
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!
