[Firmware] 2.0 beta 4 (5A258f) How to downgrade to 1.1.4 ?
I have read through the forums and what I know is that you can downgrade from beta4 to 1.1.4 even though the baseband is not the one regularly with 1.1.4.
So I did this and used Ziphone to make it boot back to normal mode. Afterwards though the phone was failing on stocks, weather, and mail. Those three things kind of worked (like maybe 25% of the time). So after that I decided to go back to the beta4 so that I would have mail working 100%.
Has anyone else experienced this?
Is there a way to downgrade the baseband firmware?
I have a macbook (with latest sdk), the phone is on AT&T legitimately. And I have never done pwnage stuff to it. All things considered this is a virgin phone.
I have read that you can use the patched Ziphone to downgrade the firmware from this page:
Before trying this, I do not understand step 6. I understand restoring it to beta 4, then after the phone is functioning fine as beta 4 connect it up to ziphone patched and downgrade the firmware. But why in step 6 would you then restore it to beta4 again? Wouldnt that just overwrite the firmware again?
Any help is thankful,
Beta4 is good, but still a little buggy. I would also like to have a phone that works the week before the firmware comes out since this firmware looks to expire early.
In my opinion, his guide is slightly off.
Simply go to DFU mode manually (hold down both buttons until it turns black, then let go of the power button. While holding home button, disconnect the cable and reconnect two times).
Restore to 1.1.4.
Now for my test iPhone, the activation fails, so activate using iLiberty+. You should have a baseband of like 4.02
Now restore to 1.1.4.
That should give you the baseband 4.04
After I ...
>>Restore to 1.1.4.
Do I need to boot it back into normal mode or can I continue to Patched Ziphone, and downgrade?
>>Now for my test iPhone, the activation fails, so activate using iLiberty+. You should have a baseband of like 4.02
Do I need to try and activate or can I put it into DFU and restore the final time to 1.1.4?
>>Now restore to 1.1.4.

Ok, got iPhone back to 1.1.4 with 4.04.05_G. Everything seems to work except when I connect to wifi. Safari works fine but stocks, weather, and mail fail eveytime. If I turn network off and use edge they work. Any ideas?
I had all manner of craziness after downgrading. In the end I just did a regular restore through iTunes. Ie. I had downgraded to 1.1.4, this was recognized as such through iTunes. I then clicked restore, that is _just_ click restore (no option button) so it went to Factory defaults. After this I just re-pwned the phone etc etc...
Forget that guide, its useless... follow these steps:

I can't get that one to work.

I quit iTunes, then open up either iLibertyX or iNdependence.
Both have all options greyed out (because 'the device is in recovery mode') so I can't do anything.
If I try it the first way, it hangs on "Wait 2'30"' on the patched ZiPhone.
Here is what I did,
restore to 1.1.4
try "ziphone regular" to boot normal mode->boot normal mode
This usually fails so then after several attempts I put the phone in DFU mode again and restore to 1.1.4 again.
After that do "ziphone regular" to boot normal mode->boot normal mode. This should work, it always does for me at this point.
Now I close "ziphone regular" and open "ziphone patched," preform the downgrade.
After that restore to 1.1.4 one more time.
Give it a few minutes; they should kick the phone out of recovery mode and into normal boot (albeit with no network support until you reflash the bb). Just let the phone sit, with the app connected and leave it be for a few.
