3gs update without baseband -> easyest way ever!
 

after many different trys with tinnyumbrella and deleting the bootloader from the ipsw files, i found my own way... :)

when you load your restore file into itunes, itunes connect to
sourik server (if you set hosts file) or to apple server.

if blobs are saved or apple is signing your fw you whant to write to phone, then it starts flashing...

now you see on your iphone the progressbar.
now just disconnect your internet connection ;)

because itunes whant to get baseband signature from apple server, it trys to connect to the apple certifacte server, but since you disabled the internet access, itunes whont get the certificate and therefore it cant update your baseband and will quit with error code... THATS GOOD! :D

now kick your iphone out from recovery mode with tinny umbrella or iRep or whantever else you prefer to use...
your iphone is now starting with new fimrware and old baseband!


ATTENTION: i have tested it with 3G and 3GS

3G is NOT WORKING, it will update the baseband!


3GS is 100% working with my methode!


4G i dont know... dont have tested it.



so for 3GS this is the saves prozess to make update without updating your baseband....

DONT USE THIS METHODE WITH NORMAL iPHONE 3G!


i think with iphone 4 it should work too..

very nice trick! ;)

my only question is, this is for 4.2.1 right?

the problem on 3gs (NB) 4.2.1 now is "thetered" when you jailbreak even you have lower baseband, so it still a problem

it's still better to stay away from 4.2.1 (for unlockers) so you can avoid thetered jailbreak problem and stay 4.1 and lower am i right?

btw,
again very nice trick sir.oxcto ;) i know this can be useful in some way

how do you kick out of recovery if you have 4.2.1?

:eek:helloo any bosy help pls i update ipad ver.4.2 after no sound..and same thing iphone4...

pls help me argent,,,thnx

this is what is also in my mind..
u will be stuck in a tetherd jalibreak if u will update to 4.2.1..so now a days no need to save baseband all u have to care about is to keep 3gs software version lower than 4.2.1..
Any sugestion for this process will be a great help for all members...
even with 5.15 baseband u have to update base band for unlock to 6.15.

shure, i update only to 4.1.

but with this trick you can save you bb.

when i tested other tricks my bb always updatet, but without internet
connection on 2nd check it cant update.

this idea come to my mind when i reded a post here about bb downgrade and
needed certificates wich get downloded later in the update process.

Very Good Trick Indeed will test myself, on the weekend. on the 3g,3gs and 4g :)

Im sure it wont work on 4.2.1 right, due to the firmware checks?

Thank you

Best regard

do not test with 3G it will update its baseband, i have tested it.

3G dont recaive certifikate for the bb.
