Downgrade from 1.1.1 to 1.0.2 POSSIBLE NOW!

[JAYMONEY510]

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.

how do i do this on PC? I downloaded the file on my desktop and that's as far as i got.

Check the Wiki to learn how to do iPhone file transfer. That is not a discussion for this thread. It involves installing (using iBrickr or just Installer.app) the BSD Subsystems, and then OpenSSH, and then using WinSCP to drag and drop files to your iPhone. If you need more help with that, please post in the Windows modding forum.

i was always on AT&T, this downgrade worked flawlessly, i'm currently updating all my apptapp programs i can't thank who discovered this enough.

[gramirez]

Well....i have also always been with att but i have thouroughly followed the instructions everywhere and i just can't seem to get my wireless services working i can't make a phone call or anything :-(

ok SiLeNtKiLLa where r u getting your lockdown file? i only have the one that went with unlock files, i dont have the original file.

Hi,

i got back to 1.0.2 and got it activated using lockdownd but only ibrickr can see my system files. What i mean to say is , ibrickr can see my phone jail broken, but via ssh or terminal i can only see 2 directories .

Library and Media

I tried jailbreaking again and again..same problem. This has only happened after i had unlocked my phone...any ideas?

[BLOWNCO]

just did it and it works thanks a ton

ok so this seems to have worked for me (sort of)

as previously posted by another member I am able to get into the iphone now and all modding is possible but no phone service due to the bad IMEI number that was changed with the 1.1.1 update.

what needs to be done now (i know it's possible since apple did it to my phone) is to change the software IMEI to reflect the real one on the back of my phone. After that is done I'm more than sure that I'll be able to use the phone feature of the iphone.

after this important discovery instead of ibrick I have a iPhone Touch (everything works including wifi)

eagerly looking forward to the next discovery.

unlocked iphone with no phone service... we're getting closer

I'm on AT&T but my active AT&T sim in my newly purchased iphone today (had to get one since cannot be without phone) and it still continues to display "Incorrect SIM" not instead of the previous message that I received.

Hello everyone !

I follow all instructions to go back to 1.0.2, but after i start restore, it gives me this message ( Please help !!!

you have to make sure the screen is blank and does NOT have the yellow triangle on the screen. only after you use tapp then you'll see the yellow triangle

you'll get a similar error but the number in the () is different (for me anyway it was a 3-4 digit number)

Can't seem to find the answer Im looking for. If I bought a NEW phone, has the 1.1.1.1 firmware, would I be able to downgrade and SIM unlock the phone? Any answers would be great. Most of the posts seem to be dealing with people updating then downgrading.

It's good to be back to 1.02

Im still trying to find all the information I can but so far from what Ive read, if you have already unlocked your phone, the modem firmware should be the old one. This means, your phone SHOULD be unlocked.

I answered my own question too, if you get a brand new Iphone, you can't unlock it unless you use a backdoor method. So pretty much all you can do with a brand new Iphone for people looking to Sim Unlock it, is have an Ipod Touch.

[HORTON16]

is this safe?

are there any negative results?

if i upgrade back to 1.1.1 with apps on my phone will i get bricked?

[DeadCode2k]

Thanks man this thing worked. last night I could not get this thing to work for me I was getting pissed but now my phone works. I don't have phone access I'm just happy too be able to use it and not having it as a brick.

thanks again to everybody who made this possible : )
