Reading an SD card with bootlader image on it - Upgrading, Modifying and Unlocking

Hi Guys
Is there any way to copy an image from an sd card so that i can make changes and then write the image back to another card.
I can create a custom extended rom and then save it to an sd card using mty. The problem is i have to change a single file for each image we use and this requires making up a new extended rom image, i would like to be able to extract this file from the sd card image change it and then re-write the image to an sd card.
any ideas
thanks

When you do full stock RUU , the sd card dont have nothing to do , just Internally. But you can format the sd card and put the factory SD folder i prepared and zip in here: http://www.mediafire.com/?6vm3l1d47kx2vs8 Decompress the file and open it and throw all the folders inside in you SD card after format. You SD card will show up as factory
Enjoy it!!

What are you talking about????? The OP clearly asked if anybody had the original files from the stock SD card, thats what he was giving him, a way to return his card to stock. Of course he doesn't HAVE to do that to his SD card but for whatever reason he WANTS to.

How to properly swap over to new SD card

Hey guys, about to purchase a 32GB SD card and was wondering what the process was. Do I connect both the phone and the SD card to my laptop and just pretty much drag the whole "Removable Disk" from my phone to the new SD card and just swap them? Or is there a more complicated process?
If ur old SD card is not partitioned then just make sure u can view hidden files and copy full contents straight over to the new card.

Can you explain that in a way that an idiot can understand it?
I will be replacing the stock 8GB SD card.

Greetings fmedina2,
That means that insure that what ever file manager your using (no one knows what OS your computer has), find the settings that allow you to decide what is shown within each directory - owner, permissions, date/time created, date/time modified, etc...
Just make sure that the "show hidden/system files" option is shown - extensions too, if it's available.
This will insure that you will not overlook any files, when you attempt to copy them over to your new sdcard.

where to put Rom, using Android File Transfer (MAC)

I'm about to flash a Rom, when I open up Android File Transfer, do I put the ROM in the "SD Card" folder ? Just want to make sure I am putting it in the right spot.
yes, put it in the sd card folder
if you put it outside that folder, then it will get deleted when you wipe your data before installing the new rom!
also, clockwork mod only allows you to install from your sd card

[Q] SD card vs. External SD card

So I've always placed my zipped ROMs on my External SD card. Now I'm getting ready to flash an ICS ROM and read the instructions for the first time in a long while and I see that I should put the zipped ROM file on the "SD card".
I guess I always think of an SD card as being an external item. Is the root directory an sd card also? Not the same as the external SD card?
I see in ES File explorer Root is listed as "/sdcard " and clearly not the same as "/sdcard/external_sd"
So where should my flash-able zip files be before flashing?
Thanks
Place on external sd

[Q] Question about booting from External SD

So you obtained this compressed image debrick_sph_l710.img.xz
Now extract the .IMG file using 7-Zip (WinZip does not work),
then you write the image file to your 16-GB SD card using dd in Linux.
Now you turn your cell off and insert the new SD card.
The question is: How do you boot off this new SD card and not the cell's internal boot loader?
Do you just power up?
Do you need to use the Download Mode method, or the Recovery Mode method?
Maybe your internal boot loader has to be damaged before the cell even looks at the external SD.
Anyone have ideas on this?
Thanks.
