Downgrade from 1.1.1 to 1.0.2 POSSIBLE NOW!

[mikef]

i already have it but im just making sure that i can downgrade with out screwing this all up!!! maybe ill wait a few days till this gets revised, or the dev team just comes up with a program to do this for me, without me ******* this up!

[Hackme]

no, when you downgrade you should only be doing it for 1 of 2 reasons
-you want to be able to mod
-your locked out with a bad IMEI
when you downgrade to 1.0.2 the 1.1.1 features dont stay on the phone.

[mikef]

well i figured that! i just wanna mod my **** again, but ive heard some horror stories about no wifi and another guy said his comes up with a sim error, and he had an att account. ILL WAIT.... no big deal

[tamasb]

Great!!!! You guys made my day!!!!

[Murfunit]

you need to use winstaller or something equivalent to bypass activation screen

Ok dug out my copy of PACAY, took out my SIM so the IMEI reset to the true one and it orked

Thanks

[DoerrFan]

This is a huge step, and i cannot thank the guy who did this enough!

If this works, i am saved
I will not be trying it out though, at least not until the Dev Team releases there tool to restore to a factory like state, or give the go that this method is safe.

For you guys with the incorrect sim issues... my process has been confirmed here.. http://www.hackint0sh.org/forum/show...1&postcount=61 just upload the hacked lockdwnd file to your iPhone, and you should be in good shape.

read back to the first page, my first post.

[larryblaw]

Worked like a charm for me.

[gramirez]

well i did do that i downloaded the one from this site and used it but still says that incorrect sim too also i still have that 0000 imei when i check the about section but when i reboot with the sim out of it it goes back to normal

[Kyle Matthews]

so even if i am on att and never unlocked the phone this will work?? and i want to hear this from PF!!!!!! ive heard that wifi wont work?????????or is that with an unlock different sim?

please make me a happy person and confirm this

Yes, everything will work.

i am on mac? could i use apptapp

Yes.

Can someone tell me how to get the acutal phone part to start working after the downgrade? Everything works except for the phone part. I have att so i dont know what the problem is. I get invalid sim messages every time i start my phone. I tried anySIM but it gives me an error saying that my iphone firmware is already patched and then it closes.

Install the modded lockdownd file into usr/libexec.

I still have a slight understanding on the ending effect as I'm seeing mixed results... Are you guys still able to access the 1.1.1 features, but still under the 1.0.2 firmware after this proccess??

No. Just downgrades for modding purposes.

im not getting the yellow triangle. im getting a 30pin connector with an arrow pointing to the itunes icon

what up with this?

You are not doing the button combination in the correct order. Hold down both buttons for 10 seconds, then let go of the Sleep button (top button) until iTunes sees the iPhone. Then let go. It should be blank screen on the iPhone, then you can proceed.

Right. You have to do this with the SIM out if you have unlocked the iPhone previously.

Wow you all are desperate

[gramirez]

So....im getting the same result i put the modded lockdownd file without the sim card in there i reboot the phone and then put the sim card in and i still get the sim not being recognized... :-(
