How to make raw eMMC backups

while device is booted you can read and extract partitions from the main /dev/block/mmcblk0. this will work regardless of S-ON/S-OFF

to backup entire device -

dd if=/dev/block/mmcblk0 of=/sdcard/mmcblk0.img

to backup just a partition-

here are the partitions we know about

to backup a partition youll need the following information:

the command to extract a single partition outua mmcblk

say if you wanted mmcblk0p19 radio-config. you would use the following command

you can also change the above command to use dd if=/sdcard/imagename.img and extract partitions from a full mmcblock dump.

Goldcarding

will this help with downgrading or anything? no. :(

1 - Download goldcard helper from market.

2 - notee the reverse CID for mmc1.

3 - go to http://psas.revskills.de/?q=goldcard and put in the reverse CID in exactly

4 - download a hex editor, windows can use HxD (http://mh-nexus.de/en/downloads.php?product=HxD) but anything hexeditor that can write to disk will be ok

5 - open hxd without your sdcard in. go to extra -> open disk note under removable devices what is there.

6 - attach sd card go to new physical disk NOT the logical disk. uncheck read only, when it asks sector size is 512.

7 - now go to file open and open the goldcard img you got in email from revskill

8 - your goldcard img will be from offsets 00000000 - 00000170. copy it all

9 - now go over to the physical disk of ur sdcard. select the same 00000000 - 00000170 sectors and paste write in the goldcard info (it should overwrite the existing sectors, if it inserts this before existing data you did it wrong)

10 - press save, now reboot phone. if you did it right your sdcard will still be accessable. if you did it wrong youll get a message you need to format.

now try downgrading with a pg86img.zip and let us know, hopefully you wont get a version mismatch and it will let you flash a lower ruu.
