[1.1.4 (1.1.2OTB)][Advice] Downgrade to 1.1.2

**Tiesto_57** · 04-09-2008 10:57 AM

I want to downgrade my iphone fully back to 1.1.2... I just wanna know if this method works:
1.Use the Refurbish option in Ziphone v2.4
2.Restore to 1.1.2 through iTunes
3.Jailbreak/Activate/Unlock using Ziphone
4.Restore Backup files from iTunes

Is that safe ? Does it work ? Is there any better way for doing it ?
I really need advice on this. So any help is appreciated
Thanks !!

Well you could do it like that but ziphone would downgrade your bootloader but there is a way back thanks to boot nutuer, if you want to save time I would think the easiest way would to get the boot nutuer app from installer downgrade to 3.9bl then restore to 1.1.2, jailbreak/unlock with ziphone and have installer downgrade the baseband. Then bootnutuer back to 4.6 that might be a way but I have never tried it seeing as how I am 1.1.1 OTB , sorry I can't be more helpful

dude,

first you need to downgrade your baseband:

if you are on 1.1.4 BL4.6 then use iliberty to downgrade your BL to 3.9 FB.
then there is a package to doungrade your baseband to 04.02.13_G but this only works on BL 3.9 thats why you need to downgrade your BL first.

after that just shift restore to 1.1.2 using itunes.

if you want to have BL 4.6 again all you have to to is install BootNeuter and upgrade your BL and you will end up on 1.1.2 BL 4.6 and baseban 04.02.13_G

i dont recommend you using ziphone for anything, it looks like creates more problems that it solves.

hope this helps

Can i use bootneuter to downgrade my bootloader to 3.9 instead of using iliberty to downgrade before downgrading the baseband ?
And if you're saying i should not use ziphone, then after i restore to 1.1.2, how should i jailbreak/activate/unlock the iphone ? What can i use other than ziphone ??
