Hi,
I have 2 tablets running an ancient android version, they have the 'Allwinner A33' chipset.
One tablet is working and one is bricked (bootloader is overwritten and not working).
From the working tablet I copied all the /dev/block partitions using "adb pull /dev/block/mmcblk0 mmcblk0.img" and the mmcblk0boot0 and mmcblk0boot1 to my linux pc.
The bricked tablet starts up in Sunxi FEL mode.
Code:

AWUSBFEX soc=00001667(A33) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000
Howto write the bootloader (or complete mmcblk0) from the working tablet to the bricked one?
Where to start?
Any help would be greatly appreciated!
Best Regards,
Donald.

When I write the mmcblk0.img to a sdcard using dd it boots android from the sdcard on the bricked tablet, I can enter fastboot mode or open a root shell using adb shell, how can I flash the internal memory? It sees the sdcard as mmcblk0 instead of the internal emmc.
Some info from the working tablet:

@Megapearl while I am aware of the FEL mode and the Sunxi tools, I could not figure-out how to actually flash a device using them. Instead I discovered that Allwinner devices can be flashed using the Phoenixcard utility and a suitable ROM. The hardest part was finding a ROM that matched my hardware.
Phoenixcard enables the creation of an SD as either Product which will be automatically flashed to the device when it is powered-on (remember to remove the SD once it's done) or as Startup which is a "Live" bootable version which is what you have already created using DD.
There is also the ImgRepacker tool that packs/unpacks the images which is useful as it allows the partition images to be replaced eg replacing the recovery partition.
Note that the ROMs are not disk images. There are some files that are partition images but there are also various other files for configuration etc. I hope this helps.

I am trying to put system and boot.img!
I tried dd if=/dev/block/stl12 of=/sdcard/system.img and it shows a pound at the end I check my sdcard and there is nothing there? Is there something I'm doing wrong?

/proc/mounts only shows currently mounted partitions, and not boot neither recovery are ever mounted. Instead check either /proc/mtd (for NAND) or in the partition table (for MMC, use fdisk).
If NAND, there's no guarantee the boot loader exposes those partitions to the kernel at all, though.
i tried using /proc/mtd but it says file missing.
how to use fdisk?

Good enough, now you can start mapping all your partitions. Compare this to the mount list, and mark e.g. nande as data, etc. After a while you'll get a few unknown left, potential candidates for boot and recovery you can examine more carefully.
thanks very much.

I'd guess nandc and nandg, they seems about the right size and not mounted. dd them to a file and examine them if they've got the format mkbootimg produces. Those files should begin with "ANDROID!".
# dd if=/dev/block/nandg of=/sdcard/isthisboot.img
Hey everyone,
I'm having trouble extracting a recovery.img from my phone. More specific I can't seem to find which file I have to 'dd' to create the img file.

Even by running the commands above I'm still not able to determine where I can extract a recovery.img.
Ive been looking around and can't seem to find anything so I hope someone can point me in the right direction.

Thanks for the help!

Hi,
I'm having problems mounting the data partition on my Galaxy Mini. Below is the steps I have taken. I'm just guessing bml12 is the data partition.
When I try and mount bml12 as rfs with read write using the command "# mount -o rw -t rfs /dev/block/bml12 /data" i get the error message "mount: Invalid argument". But when command appears to work for mounting stl14.
Any help or guidance would be greatly appreciated.
Thanks

I'm trying to dump the boot.img in the hopes of porting CWM and, eventually, CM11 to the Lenovo B8080, better known as the Lenovo Yoga 10 HD+. But I'm at a loss how to extract the boot.img.
I've been following this guide here: http://xda-university.com/as-a-developer/porting-clockworkmod-recovery-to-a-new-device and am stuck at trying to extract my boot.img as the binary is missing. All I get is
Code:
$ dump_image boot /storage/sdcard1/boot.img
dump_image: not found
I've also tried using romdump but the binary that I found won't run on the b8080, wrong architecture.
Lastly, I tried
Code:
$ cat /proc/mtd
as recommended in this guide: http://www.addictivetips.com/mobile...es-boot-recovery-and-system-partition-images/
but that also doesn't work as there is no "/proc/mtd".
What I do have is the following output:
Code:
$ cat /proc/partitions

Anny update ?
