hello guys,
after that i4 problem with ultrasn0w, @daich tested some ideas for me. He successfully made ultrasn0w works.

Please note, I have only done this on one phone only.
Actually, after doing this, I did a restore and it stopped working so
I did it again according to these exact steps and it worked again, so
on the same phone it is repeatable.
This worked for me but your situation may be different so try at your
own risk, I take no responsibility of the outcome.

Hardware used:
OSX mountain lion(can be windows or other OSX version)
iPhone 4 with baseband 1.59.00
Locked out SIM inserted in the phone.

Software used:
redsn0w_mac_0.9.15b3
iPhone3,1_6.1.2_10B146_Restore.ipsw
iPhone3,1_6.0_10A403_Restore.ipsw

1. redsn0w -> extras -> even more -> restore -> ipsw -> choose 6.1.2
firmware -> “YES” to prevent baseband upgrade -> follow directions to
finish upgrade to 6.1.2

this will put your phone into recovery mode. no worries.

2. redsn0w -> extras -> select ipsw -> choose 6.0 firmware ->
“Successfully identified”

this will cause the next step to use the 6.0 firmware

3. redsn0w -> extras -> recovery fix -> follow directions to execute the fix.

after this step, you will be on 6.1.2 with baseband 1.59.00 with no jailbreak.
from here, if you have a sim workable on the network, you could
possibly activate it and jump to step 8 and jailbreak with evasi0n
(untested)

4. redsn0w -> extras -> select ipsw -> choose 6.0 firmware ->
“Successfully identified”

this will cause the next step to use the 6.0 firmware (you have to do
this again even after step 2)

5. redsn0w -> jailbreak -> follow directions (make sure cydia gets installed)

after this step, you phone will be in a tethered jailbroken state and
also activated.
next, do a tethered jailbreak boot.

6. redsn0w -> extras -> select ipsw -> choose 6.0 firmware ->
“Successfully identified”

should be the last time…

7. redsn0w -> extras – just boot

this will boot into tethered jailbreak state.

8. install evasi0n untethered package on cydia.

10. open cydia again, search for ultrasn0w and install it. it will ask
you to restart springboard.

At this point, you will see the network of your sim card repeatedly
come on and then disappear.

11. shut down the phone by holding power and swiping to turn it off.

12. boot it up again and the go into Settings -> General -> Reset ->
Reset Network Settings

13. On the next boot, you should see your network come up and remain there!

Note there are still two issues:
1. There will only be one signal bar showing no matter how your signal
is. I believe this is a fault between 6.1.2 not being able to
communicate properly with baseband 1.59.00
2. Your phone number under General -> Phone will be “Unknown” – this
means imessage and facetime functions wont work via your phone
number… among other things.

hope this little tutorial help! thanks again for @daich!

this one worked for me! thanks! altho the signal bar is still the same no more cycling between one signal bar and No service.

[erick_aujero]

the fix for the push imessage/facetime i got from this site. credit goes to Mohcine Ariani at ALL About Apple Is Here: The Only way to get Push notifications , Facetime and iMessage Work on your iDevice. In his website he showed how to get around the ACTIVATION REQUIRED after installling SAM. and everything to get push working. thanks to zmaster, GjCD and Mohine. thanks to all of you guys.

btw, still with one signal bar but not cycling between no service anymore. im happy with that.
