First of all, I'm new here but i've been using the community's ressources for quite a lot of time. Thanks guys, you're doing great.
I'm having a major issue with my iPhone 3GS (os 4.0.1, jailbreakme). Two days ago, I decided to reboot it. I'm now stuck in the boot sequence: the Apple logo shows up for a minute or two. Then, a spinning wheel appears, stays for about 2 other minutes and then the iphone shuts down a reinitiate a booting sequence. And that over and over again.
What I've tried so far:
- home button + power button for ten seconds
- restore the 4.0.2 firmware with iTunes (both in recovery mode and DFU mode and with two different computers)
- using iRecovery; here's the output:

CXT is not valid? I have no idea what this means but it doesn't sound good.
Plugging some iRecovery instructions doesn't work:
No output...Entering recovery mode, starting command prompt
(Recovery) iPhone$ clearenv 1
(Recovery) iPhone$ printenv
(Recovery) iPhone$ seten auto-boot true
(Recovery) iPhone$ saveenv
(Recovery) iPhone$ fsboot
I'm left clueless. I have read dozens of forum threads and I've not been able to figure it out. Needless to say that my phone is out of warranty.
I'm planning to perform these operations:
- try to downgrade to 3.1.3 (I saved my shsh at the time)
- find a way to erase the nand (but i don't know how)
Do you guys have any guess about what to do?
