[1.1.2 OTB] 04.02.13_g FULL UNLOCK easy steps !!! (old bootloader)

after couple of hours in front on my computer , finaly I manage to fully unlock my 04.02.13_g iphone.

here are the steps :
1. Downgrade to 1.1.1

2. Activate using jailbreakme

3. Go to Sources and tap edit and add http://i.unlock.no/

!!! Make sure Modem version is 04.02.13_G in Settings → General → About !!!

4. Install "BSB Subsystem" found in System.

5. Now install "BB Downgrader (1.1.2)" found in Unlocking Tools category. This will take around 5 minutes.

6. When done, restore your phone to get 1.1.1 firmware reinstalled.

7. When phone have been restored, you can Activate and unlock as normal.


Works great for me.

Are you referring to unlocking with any sim? (ex. T-Mobile, GSM sim?)

so your saying with a new OTB 1.1.2 you were able to:
restore 1.1.1 on it, then jailbreak it, then use the BB downgrader to downgrade the baseband..
but what about the bootloader 4.6?

how did u get past the bootloader?

what version of firmware did you have to beginn with? or bootloader i mean

You realise all you end up with at the end is just an unlocked 1.1.1 iPhone?

It looks like he just had a iPhone that was updated to 1.1.2 not and brand new one with bootloader 4.6

The steps posted above are simple, if anyone wants a more explained guide to downgrade from 1.1.2 to 1.1.1 then click on the link:

This defenitly does not apply to OOB 1.1.2 Bootloader 4.6 iPhones. This guy's phone must have been upgraded to 1.1.2 and was originially 1.1.1 or 1.0.2. There is no way it could have been an OOB 1.1.2 cuz the new 4.6 bootloader wouldn't let him do what he did.

I really don`t know what Bootloader I had before , I know for sure that my firmare was 04.02.13._g and now (after the second restoring -the last step-) the firmware is 04.01.13_g.

By the way after I run the BB Downgrader (1.1.2) I check the firmare and was with 13..... I don`t remember exactly.

What week was your phone built in? This should be the 4th and 5th number of your serial #? Is it after 45?
