    Right people...

    Just a quick one...

    If upgrading your eMMC to a bigger size, you have to really mess around in unix to write partition info etc etc...

    Try these payloads...

    16 - incase some lunatic wants to downgrade - MIGHT HAVE GEOMETRY WRONG ON THIS VERSION), 64, 128 and 256 GB versions in this Zip.

    Once you have rewritten your GPT using these files, restore your INDIVIDUAL partitions and BOOT0 /1 in Hekate.

    You MAY have to do it manually for the USER partition in hacdiskmount, to copy your stuff over. This means...


    You will need a rawnand of OLD EMMC to mount your old USER partition... Unless you are starting from scratch... I can make some "blank" USER folders if you need them.

    After using these files... In your new eMMC
    1) Use BIS key 3 and mount USER in hacdiskmount
    2) It will probably say it "needs to be formatted". Format it.

    It is now formatted using correct key.
    Mount your newly formatted USER partition and copy your stuff from your old partition over.

    That should be it.


    Upgrade should be done.

    I`m limited on eMMC chips, so if someone could run through these, would be great. Hence "TESTING".

    This is the "geometry" I used for your reference...

    geometry.jpg

    All bytes are little Endian.


    No warranty implied...blah blah... Using another eMMC size will "PROBABLY" get you banned. I say probably as the GUIDs are the same. The size of the last partition is different. So... Your mileage may vary.

    If Ninty are only checking GUIDs then you will probably be fine. If they are actually getting eMMC size reported to them, you aren`t fine.


    BACK EVERYTHING UP BEFORE EVEN THINKING ABOUT MESSING WITH EMMC.

    Let me know how it goes.

    Can do a 512GB version if needed. Or are they 500GB?
