MK802 III (not S): backup current firmware

[dmukhin]

Is there the way to create .img file from what is installed to device now and flash it later with RKBatchTool (in case I'm not happy with new firmware)? I don't care about downloaded apps and data, of course... Thnks

Found http://4pda.ru/forum/index.php?showt...#entry17083489 (to capture dump) and http://4pda.ru/forum/index.php?showt...#entry21805117 (to assemble .img). Both on Russian, sorry...

Thank you, will wait for that information... Meanwhile I tried romdump from first link above and it didn't extract kernel, so not really useful

[neomode]

Try this:

Insert that sd card in TV Stick


[Using Android Terminal emulator performs the steps below:]


Become a super user:
su


Navigate to the sdcard location.
cd /sdcard




Check partition number and partition name
cat /proc/mtd
//Make sure that the partition no's and names match as shown below. Otherwise edit the commands to match the partitions with the corresponding Image name.


Dump the bootloader image:
dd if=/dev/block/mtdblock0 of=/sdcard/bootloader.img


Dump the kernel image:
dd if=/dev/block/mtdblock1 of=/sdcard/kernel.img


Dump the boot image:
dd if=/dev/block/mtdblock2 of=/sdcard/boot.img


Dump the system image:
/data/rkdump /dev/block/mtdblock3 of=/sdcard/system.img


Dump the recovery image:
dd if=/dev/block/mtdblock4 of=/sdcard/recovery.img

Then copy the Files to PC

Thank you.

I have no "bootloader" partition but there are "misc", "kpanic" and "backup" partitions... Is it that one?

Also what should I do with all those image files? I mean when I tried to unpack another stock ROM with tool I downloaded by second link I got also some script and config files... What tool should I use to assemble whole ROM image file from captured partition dumps?

Oh, just figured out, I also have no /data/rkdump...

Well, my backup partition seems to contain something but I don't know how to decode it... And Rikomagic support wrote to me that they do not have that version downloadable too So, I'm stuck now...
