[arcadian9]

I want to downgrade back to 1.1.4 ive been having soo many problems with 2.1 mainly with no wifi
i tried restore to 1.1.4 in itunes but i get an unknown error message (20)
can someone help me

does anyone have the .ipsw file for the 1.1.4 firmware, because i might need it to, in case my upgrading will go wrong.

will downgrading completely reflash my baseband because my wifi is really messed up once i upgraded 2.1 with quickpwn

[xXxRomero]

no.... i dont think so at least.. it tells you how to downgrade your baseband there also

errrr ok i used that tutorial and after step ten where it asks you to use one of the unlocking method i used iliberty and supposely when i run iliberty with itunes it should kick my iphone out of recovery mode but it doesnt and its still in DFU mode and i cant run iliberty to jailbreak it cause it says i have to be in normal mode
grrr

[xXxRomero]

i think you need to put it in recovery mode now, not in dfu anymore.. not sure

That's exactly why I won't upgrade my iPhone 1G!

thanks for the tutorial
gonna leave my phone as it is now

I want to share my experience when I downgraded my 2.1 to 1.1.4, well, first every thing was okay until step 10 from the tutorial, I was unable to unlock using iLiberty+ so I said to myself why I don't use ziphone, I used it and I was able to unlock the phone after I switched my device to restore mode, but there was no installer, so I went back to itunes and restored to the firmware 1.1.4 another time, after that I was able to unlock the phone using iLiberty+ with the installer.

I don't know if this will be helpful for anyone, but It worked with me.
and thanks for the tutorial.
