My iPhone 8GB OTB 1.1.2 was working just finel (unlocked) when i updates to 1.1.3 with Nate True's method. 1.1.3 worked well to but i want it to go back to 1.1.2 so i downgraded to 1.1.1 to jailbreak and update to 1.1.2. I couldn't jailbreak 1.1.1, every time i installed AppSnap iPhone wouldn't reboot so didn't get to sprinboard. I've tried this with 2 different PC's en waited 2 a 3 hours for in case there were server issues with jailbreakme.com.

So i restored the iphone in itunes and it updated to original 1.1.3 ! Tried to restore it again to 1.1.1 but got every time error in itunes can't restore it (1) so i've tried this method:

If your restore fails quickly, you have to make the iPhone a little more receptive. Grab the classic iBrickr, and open it up while your phone is in the "Connect to iTunes" mode. There will be an option
to "Begin the downgrade to firmware 1.0.2". Click that one. Your iPhone screen will turn white and iTunes will again complain about restoring. Do the Shift-Restore trick again, and this time it will work, minus the 1015 error, which iBrickr can get around (restart iBrickr when it happens).

While downloading 1.0.2 in iBrickr my iphone went to green screen en iBrickr did'nt respond any more. Tried to restart iBrickr en clicked on "Free my iPhone" but iphone went crazy en start rebooting in loop en showing weird stuff.

See this video I've made: DOWNLOAD

- I've tried to put the iphone in recover mode but this is not possible, only thins it does is turning iphone off after 25 sec and when i turned back on it start rebootin in loop again.

- iPhone wont recognized in itunes, iBrickr or any other program

Is there something else i can try ? Some one have a solution for this ?

Btw, sorry for my bad English...

Ok, I've made some progress !

I've connected the iPhone it to a power supply (not computer) and recorey mode is working now ! I've restored the iPhone in itunes with original 1.1.3. No rebooting any more but locked 1.1.3 iPhone.

How can i get 1.1.2 working ?

I've now successfully downgraded the iPhone in iTunes tot 1.1.1 but after the restore (tried 2 x) i get the massage:

"Incorrect SIM - Insert an unlocked and valid SIM to activate iPhone"



It's an UK iPHone and the original O2 SIM card is in the iphone. Already tried to reboot is but it doesn't helped.

Can someone please help me out ?

Have a look at i.unlock.no
They have a lot of nice tuts.

I am in some similar situation though I would be satisfied with just the original jailbroken 1.0.2 that I had in the first place.
I am having the same issue with the (free my iphone) button in ibrickr.

Hope it helps you out.

Don't waist your time on looking for a software solution, there simply isn't any at the moment.
