Hey Everyone,

So I'm in a peculiar situation.

Trying to downgrade an iPhone from 2.0 to 1.1.4.

The iPhone was unlocked on a t-mobile network.

Had huge issues getting it to work, it was stuck in recover mode for a long time. Followed instructions to downgrade and finally got it to 1.1.4.

Tried to unlock on 1.1.4 and it is doing strange things.

It is not rejecting the sim card (No messages saying the sim won't work)

But its not connecting to a mobile network either.

Nor is it saying "NO SERVICE" it just has zero bars and no network description.

Also, the strangest thing is that the Network Settings are GONE.

It shows Airplane Mode, and then Wi-Fi settings, but the MOBILE NETWORK option is no longer there.

I don't have a backup phone, so I'm at a pretty big loss until I can get this working.

Any tips or ideas?

FYI I downgraded using Pwnage and unlocked with ZiPhone. In retrospect, probably not the best idea to combine these two, but that's what happened.

Here is a photo of the Network Settings gone.

Thanks in Advance!

google: iphone baseband
 
I'm in the same boat.

When you downgrade the Firmware to 1.1.4 the Baseband (I guess basically the modems driver/firmware) is left at the version 2.0 set.

You're going to need to downgrade that as well. There is a modded version of Ziphone and BootNeuter that work for different people, but neither work for me. I've repeatedly tried about 3 dozen times.
 
Im in the same boat, looking at ZiPhone (the app i used to unlock) there are a couple of options to do with "baseband"

- iErase BL 3.9 baseband (refurbish)

and

- Downgrade 4.6 BL to 3.9 & Flash / Unlock 4.03

Would either of these options suffice in getting back network??
 
I can't remember if it was ZiPhone or iLiberty, but I was scanning the text as the iPhone was being flashed and I saw an error line that it didn't recognize the 2.0 Baseband 04.05.04_G.

Thats why I think you have to use the BootNeuter or modified ZiPhone to do this.

More information on this issue is found here: https://forums.macrumors.com/threads/517872/

It looks like it's worked for quite a few people. Hasn't worked for me yet. I'll try again tonight
 
update guys!

Ive got it working!!!

All I did was download the ziPhone patch from

http://kerdsri.com/2008/07/14/downgrade-iphone-firmware-20-to-14/

and run the baseband downgrade.

Full credit goes to you Denaes for linking me to the correct page! I owe ya pal.

Only other thing I have found, is that all my settings (such as dialing format) are all in US and Im in England. Is there an easy way to rectify this?

Thanks once again!

p.s. colione, PM me if ya need any help!

EDIT: Figured it out, it was under settings DUH! :)
 
I just wanted to add that I went home, ran the modified ZiPhone to downgrade the baseband and it took like 3 minutes and worked!

The only thing I did differently was that the iPhone was was totally dry. I had to plug it in for 5 minutes to do anything at all on it.

So I'm down to 1.1.4 and making calls on T-Mobile :)
 
No service solution

Six days it took messing around to find this...

This is a simple version of several thousand million various attempts, cobbled together from some hundred or so posts, some bogus, some unreadable, in order to convince my iPhone that the sim card actually does work...

Being Irish, I would prefer to be out drinking than spending countless nights infront of my Mac.. Anyway here goes...

The downloads you will need are; (Download all of these to the desktop for your own sanity)
iTunes 7.5
http://www.filehippo.com/download_itunes/?3402
Iphone 1.1.4 Firmware
http://www.tuaw.com/2008/02/26/ipod-iphone-firmware-update-1-1-4-released/
iBrickr
http://cre.ations.net/creation/ibrickr (This is windows ONLY)
Ziphone 3
http://www.ziphone.org/
Kiphone
http://iphone-freak.com/en/page2/page2.html

Ok so you've downloaded all of these, lets get started...

1. Upgrade your iPhone to Version 2 software through iTunes as normal, and wait for the Sim locked message. You need to do this to normalise your iPhone again incase any previous messing around did anything nasty.

2. Uninstall iTunes if it is a higher version than 7.5 and install iTunes 7.5 (You need to do this to avoid the annoying Error 1604). Some of you may have a problem on the mac when downgrading to iTunes 7.5 (Library error). You need to go to finder click on /Users/Username/Music/iTunes you should see the "iTunes Library" file. MOVE it somewhere safe. YOU DO NOT HAVE TO DELETE THIS FILE, if you do you will have to redo all your playlists etc, believe me I made this mistake (Thank God for Time Machine!!). iTunes 7.5 should launch away

3. Restore your iPhone to 1.1.4. Do this by docking your iPhone and hold down the Option key (Mac) or Shift key (PC) and click on restore. Point iTunes to the 1.1.4 firmware you downloaded earlier. Sit back and relax, you deserve a coffee.

4. Don't panic, you should get an "Error 10xx", usually 1015, this is ok. Take a sip of coffee, a deep breath and proceed.

5. Load up iBrickr, you will need a PC for this if you have a Mac or just fire up Parallels / VMWare. Luckily I had access to an old laptop. iBrickr should recognise your iPhone as being connected.

6. iBrickr (V0.91) has only two options, click the "Boot phone" button. The screen will turn red, this is normal, be patient it takes a couple of minutes to reboot.

7. You should now have have a 1.1.4 iPhone with a baseband from V2 (Who cares, its technical and we don't need to get into it here)

8. Run ZiPhone and use the "Do it all" option. Make another coffee, this takes 10 minutes or more.

9. You now have a jailbroken phone, with a "No Service" problem. Great.

10. Load up KiPhone. click on "iErase" (Mac) or "debug boot" and "Erase baseband" (PC). I HAD MORE SUCCESS WITH THE PC VERSION. The Mac version hung twice, it's your choice but for your own sanity maybe try the PC Version.

11. Enjoy, you should have full service back.

12. Dock with iTunes, it will ask you if you want to upgrade your iPhone, make sure to click the "Do not ask me again" button and click don't upgrade. Otherwise you will be back at square one.

13. Drink lots of beer, Apple you should be ashamed of yourselves, I wasted the majority of six days of my life to get this problem sorted. Pity-full. :mad::mad::mad:
