i have an accidentally 1.1.2 updated iphone.. successfully downgraded the main firmware but when i try to downgrade the modem firmware the process starts and when its flashing the baseband suddenly reports an "Error Main script execution failed!" and then it wont do anything... just gets back to the 1.1.1 firmware whit the 04.02.13 modem. any ideas???

what script are you running? is it specifically for downgrading 4.02.13?

Run ireaser (get 1.1.2 secpack first) then run bbupdater -e etc. etc.

im not running any script, im using the i.unlock.no BB downgrader. if there is no other way guess i have to use the ieraser etc. etc.. but thx for the help!

huuuuuuuuuu
you have the new bootloader 4.6... i have the same problem

check with bbupd.ater -v

U can´t unlock yet.

You need to downgrade your firmware from 1.1.2 back to 1.1.1 then run BB Downgrader, if it still doesn't work, downgrade it again back to 1.0.2 then run it. it should work. I did mine like that.

You then virginize it then upgrade it back to 1.1.1, but if you want to upgrade it to 1.1.2 then let me know that do you successfull or not and how. I'm still having problem with my upgrade to 1.1.2. I can't jailbreak even though I installed oktoPrep already.

Thanks and good luck

No need to virginize.
Once baseband is downgraded. You can follow this "airplane" way to go up to 1.1.2

You're right. after I did the BB Downgrader. my base band now is 03 not 04. I then can't run anySIM 1.1.1 anymore. I already installed BSD Subsystem and open SSH along with other stuff. I did this once but I forgot already. How should I fix this?

Bottom line is that i have a firmware of 1.1.1, base band is 03 not 04. and can't run anySIm 1.1.

Please help Dtube. Thanks.

Um your problem is that baseband 3 is only for 1.02. If you downgrade to 1.0.2 then up to 1.1.1 it will give you the 4.01 or whatever basebande for 1.1.1.

That is exactly what the script does... Does it fail just as it starts flashing, or when it's done flashing (after about 2 minutes of waiting).

What happened when you run anySIM 1.1 ?
Did anySIM 1.1 give you an error when you run it OR you don't know how to put anySIM on the phone?.
Please tell me what you want to do with the phone. Do you want to have 1.1.1 & unlocked or do you want 1.1.2 & unlocked? or do you want 1.0.2 & unlocked ?
