    Default [1.1.2 OTB] Can we H/W downgrade BL without open it?

    tried open iphone, so diffcult to remove the black cover. after 40 minutes trying and get removed with little scratches. give up the metal cover remove.
    so I am thinking, is there anyway we can H/W downgrade it without open it? maybe we can find some solutions over the Ipod connector. maybe we can put 1.8V ot even 3V+ votage on some pins of the connector and make it work same as test point?

    will try oneday!

    With this unlock method you have to connect two points on the board that are not physically connected to each other, so in my understanding it is IMPOSSIBLE to connect those points without opening the phone.
    You are going to make the effort and open the case. There are many different methods here in the forum that all seem to work. I found a knife to be the easiest of them all. Just read yourself through the guides/tutorials and find the method that suits you most.
    I actually opened the phone in about 30 minutes, most other members took a lot more time up to 3,5 hours i think.
    So good luck!

    But it is worth the effort I think!!

    if you don't open it, then it wouldn't be called a h/w downgrade.. and you go ahead and try it. say goodbye to your $400+ investment.

    The short answer: No

    The dock connector pins has nothing to do with the test points.
    And if you could do it through the connector pins, you could do it with software.

    If you can downgrade without opening it would be a SOFTWARE downgrade...
    At the moment the HARDWARE solution is for most people the only way to downgrade the bootloader.
    (But it should be possible to downgrade without opening. Itīs already possible with bbupdater but nobody has a correct fls file... )

    I was able to remove both covers by looking at that google video. It would be hard.

    If you are able to do that ... then you dont have a H/W unlock but a S/W unlock
