    Hi,

    I successfully reflashed my new superpad last week and I'm now ready to try this froyo jobbie :-
    http://www.androidtablets.net/forum...2-2-running-ft2-series-tablets-confirmed.html

    However my 1GB currently shows as 700mb after it went through winhex on the previous flash.

    The instructions on the above froyo flash ask for at least 1gb, so how do I get winhex to refresh it back so I can put the new image on it?

    Can anyone plase guide me?
    Thx

    ...crumbs I think I busted the 1mb card. I thought I successfully wrote the froyo image to the card, but it didn't work. And when I tried to look at it again in either Winhex or the HP USB prog, neither recognise the card any more ...

    :-(

    ok you need to do this in three stages to recover your card:

    you will need:

    * at least 2X microSD card readers (usb)
    * a second SD card
    * a computer running win 7
    * HP USB Disk Storage Format Tool

    stage 1:

    * use your working SD card and make sure both card readers function
    * place BOTH readers in there USB slots and confirm drive letters (eg: drive c-d-e etc.)
    * backup your functioning sd cards data

    Stage 2:

    * place your known working SD card in drive A and perform a format using Windows top FAT32
    * place your non functioning drive in reader B wait for command prompt to format (do nothing at this stage)
    * boot HP USB Disk Storage Format Tool with admin privilages

    Stage 3:

    * you now have two readers and two drive letters associated with them
    * using HP USB Disk Storage Format Tool locate the working SD card's drive
    * format the card using HP USB Disk Storage Format Tool to FAT32
    * when complete quickly remove the card and swap it with the non functional card
    * ignore windows prompts and using the same drive letter but different card use the HP USB Disk Storage Format Tool
    * with a little luck your broken SD card will now start to format back to its original size


    this can be done with a single card reader but is much more of a pain in the ass

    if this fails follow stages 2-3 again, if that fails move on to MiniTool Partition Wizard Home Edition (google it and download the free version) and have it work its magic on your cards partitions.

    Try the freebie Minitool partition wizard home edition v5.2. It works on usb flashdrives, may work on sd's.

    you could attempt this with your current OS but i can only confirm functionality with Win7 at this time, i cant see why it wouldnt work.

    after all its better to try and fail than not try at all
