the only problem here stated that becoz of the baseband problem so that is why is not able to work with ipad 2 3g
izzit possible if singapore does not have this baseband lock to any telco the guide some how will work?
do advise and correct my understanding.
Please don't link to external sites as per our rules. We have better tutorials than that already in our tutorials section, so please search and review those along with our rules! Thanks.
You cannot downgrade your iPad without SHSH Blobs for the version you want to downgrade to. EVER. No exceptions. You do not have those, so as we stated earlier, you have no way to downgrade.
If you had save SHSH Blobs for 4.3.3 (and to be clear you CANNOT get them now) then you could downgrade your iPad2 to 4.3.3.
The baseband is the operating software which the modem in your 3G device. Whether your device is carrier locked or unlocked is irrelevant. All 3G devices still run the same baseband software, and this gets upgraded over time, just like IOS does. The baseband of any iPad can never be downgraded. It is impossible.
Apple introduced a new countermeasure in the firmware restore process recently so that if your baseband update does not complete successfully then the entire firmware upgrade will fail, leaving you in an endless restore loop. At the moment, IOS 4.3.3, 4.3.4, and 4.3.5 ALL have the same version baseband, and it is also the current baseband which Apple is signing.
For this reason, you can downgrade from 4.3.5 to 4.3.3 if you also have blobs. But you cannot, for example, downgrade an iPad2 from 4.3.5 to 4.3 because they have different baseband versions and the failure of the baseband update will cause a failure of the entire restore procedure.
I appreciate you are very frustrated and desperately want a way to jailbreak your iPad2, but at the moment you have no opportunity to do so. Any site which says you can is incorrect I'm afraid. You will need to wait until a new JB method is released (or an existing one updated) for iPad2, and probably for IOS5.
Hope that clarifies.
