I unlock my iphone 3G baseband 2.30! :)

[madz_freak]

Guys,

i finally found a way to unlock my iphone 3G by downgrading baseband 2.30 to baseband 2.28..my iphone is working with software version 2.2.1 and baseband 2.28 with all networks (telenor, mobilink, warid, ufone)

since it is a huge for almost all iphone users who have updated firmware so i'm sharing this...

This thing only works if your bootloader is version 5.8 (will not work if it is 5.9)

though i tried a diffcult method to do..but i'm explaning this a bit easier here..

make sure your iphone is jailbroken and you are able to use internet via WiFi on iphone...

Just go to Cydia and search for "3G Baseband Downgrade" .That's all you need. Download and install that and then you should see an APP with an unlocked LOCK on it that says 3GBBD and then press that and it will downgrade your baseband 2.30 to 2.28! then just use usual yellowSnow...

to confirm go to settings ] general ] about ] modem firmware (It should be 2.28)

i've checked all networks and they are working fine

But if your iPhone was manufactured after Sep. 08 it will not work which means you must have a 5.8 bootloader. But at least try it, it won't harm ur iphone

Good Luck !

how to find out da bootloader version ...?/
btw currently im using a turbo sim but usually haf problems with it ...so desperately want to unlock it

[hsnmz]

I am using mine with turbo sim with no problems what so ever.

often i get pop up sayin No SIm and suddenly it changes to NO SERVICE ...and then i restart it gets bak to normal ...i dunno how to solve this ??

@OoZy

i had the same issues with turbo sim

btw finding the bootloader version is a very hard thing...you may need to do lot of commands via SSH and Terminal..

btw better try to download and install the tool 3G Baseband Downgrade from cydia..if you have 5.8 version..it will be downgraded to version 2.28 of baseband, if you have 5.9 it won't be.... and of course it will not harm your iphone even you have 5.9 version of boot loader...so at least try it without knowing your bootloader version... Good Luck

and after successful downgrade do remove your turbo sim and just install the single sim..it will work..
