don't do this on a 1.1.4 phone -- it crashes like other apps that apparantly need/check for 1.1.3. i had to reset network connections.

up to date way of upgrading iphone (to make it easy for everybody): use itunes to upgrade, just like an unlocked iphone, to 1.1.3 then quit itunes start ziphone 2.4 unlock iphone (after that the iphone works fully) restart iphone and use ziphone 2.4 advanced options to downgrade/upgrade bootloader/baseband from BL4.6/BB04.02.13_G to BL3.9/BB04.03.13_G restart iphone and your on an iphone that works just like an unlocked iphone + it's jailbroken and has the installer.app on it... then take it from there... no media or settings are erased in that process, unlike previous upgrades that deleted all media and settings from the iphone... i tend to giving the advice to delete all 3rd part apps before doing this upgrade in order to make sure no old settings of those 3rd party apps are corrupted... just to make sure and it doesn't take that long to reinstall the 3rd party apps, the settings are not deleted by uninstalling the apps...

and why would you want to restore 1.1.1 in the 1st place??? doesn't make sense... stick to 1.1.3 !!! use ziphone 2.4 and read the read me files if you don't know how to use it...!!! reading helps, and don;t just apply stuff to your iphone if you don;t understand the underlying processes...

restore to 1.1.3, then use ziphone 2.4 to unlock. after unlocking downgrade the 4.6 bootloader to 3.9 and in the same instant ziphone upgrade the baseband to 04.03.13_G... 1.1.3 is the version t o use now! don;t mess with 1.1.1 or 1.1.2... ziphone 2.4 is for 1.1.3, and if your on bootloader 3.9 there's no need to change that... if your on bootloader 4.6 baseband 04.03.13_G can't run and your cell part of the iphone will stay silent... only BL 3.9 and BB 04.03.13_G work! BL 4.6 needs BB 04.02.13_G to work porperly... the downgrade (BL) and upgrade (BB) are to be found in the advanced option in ziphone 2.4... but first use itunes to upgrade to 1.1.3, then unlock, quit itunes, restart iphone. after that downgrade/upgrade BL/UL... if your on 1.1.1 you can't use 04.03.13_G @ all! only in 1.1.3 after applying all the ziphone features!

Hi, I had upgraded from. 1.0.2 - 1.1.1 to 1.1.2 and unlocked using anysim then upgraded to 1.1.3 using official 1.1.3-3 upgrader. Now before applying this, just reinstalled BSD n moved my fonts using boss tool (thanks all for such great work). Upgraded to 04.03.13_G. Later downloaded anysim 1.1.3 under the iclarified source, all went fine (Thanks GOD). Installed it under airplane mode on. It worked smooth. Now i have a 1.1.3 with 04.03.13_G firmware. All working well. Thanks to all for their efforts and for users to give such useful comments. Cheers

http://downloadziphone.org/ZiPhoneOSX-2.4.tbz ziphone 2.4, chose option to "Downgrade Bootloader from 4.6 to 3.9, update baseband to 4.03.13 and patch the unlock". that should be it...;-) http://www.ziphone.org

My iphone is 1.1.2 OTB phone (which has 4.6 bootloader), is there any way to upgrade the basband?

smokeonit - February 16, 2008 at 5:00am

i'm on 1.1.3, 04.02.13_G, BL 3.9, jailbreak 0.5.3. when i try the basband 1.1.3 updater i get the script error. after that my cell signal goes dead. after rebooting the iphone everthing works flawlessyl, but no changes were applied to the 04.02.13_G baseband... what is the DEV team jailbreak, the zibri or the jailbreak one? there's ziphone 2.2 and the jailbreak 0.5.3 out there right now... thnx for all answers

I try to install baseband updater but I get main script executor failure! What is the problem? someone help us

This only works on 1.1.3 systems? I looked at cusquinho's path/solution from page 7 (and quoted herein) but the only difference is that I ran this update with at the 1.1.2 stage. Meaning, i had a 1.1.1 otb with 3.9 bootloader and then i upgraded to 1.1.2. It had the 4.02.13_G baseband just before i ran the upgrade mentioned in this tutorial. I unlocked it with anySIM 1.2u. Once I installed the Upgrade mentioned in this tutorial i lost wifi and gsm. The only difference between cusquinho's path and mine is that before running the upgrade in this tutorial he first upgraded to 1.1.3 using the iphone dev teams method. So, is it that it doesnt work with 1.1.2 firmware (if it should be noted in the install file). cusquinho's post: 2008-02-06 10:07:48 Hi, AFAIK, this is what *I think* you need to get it working: * Have the 04.02.13_G radio (from 1.1.2); * Upgraded from 1.1.2 -> 1.1.3 using Dev-Team method; * Mine was unlocked, with anysim 1.2u; * Install the baseband update with enough free space on /, mine had 86 MB which I got with BossTool moving Fonts; * Wait for it to finish, install anysim 1.3; * Run anysim 1.3 in Airplane Mode (I know it seems to be working without), and autolock to never; * Wait for it to finish and reboot. That's all I did, step by step. Mine is 1.1.1 OOB, upgraded to 1.1.3 with dev team soft upgrade using 1.2 radio. (now 1.3)
