Best way to create image backup

---

Here is the situation:

I will be getting a Brand new fresh untouched A500 later in the week as a replacement for my faulty one (Micros SD slot no longer working).

I want to make a full backup of some sort to share with the XDA community. I am in Australia and know that a number of people are looking for a copy of this rom to restore back to original for whatever reason.

I believe it should be shipped with 1.016.04_Com_Gen1.

I have had experience using CWM and rooting on this device and have flashed several roms to my device in the past. I can also do a full backup in CWM. I also have a working adb.

What format does the community really want, and how do I go about creating it.
I am willing to help other by providing this rom, but want to know the best format to supply it in and get it right first go.

Step by Step instructions required please. We have a week to sort this out before I get the unit.

Cheers,

Michael.

I ll wait for it, mine was on that firmware...

Thinking this is probably the best way:

Backup the first 0x680000 bytes of mmcblk0 and all partitions (except cache + data) with dd:
dd if=/dev/block/mmcblk0 bs=512 count=13312 of=/mnt/external_sd/dumps/mmcblk0_start
dd if=/dev/block/mmcblk0p1 of=/mnt/external_sd/dumps/p1
dd if=/dev/block/mmcblk0p2 of=/mnt/external_sd/dumps/p2
dd if=/dev/block/mmcblk0p3 of=/mnt/external_sd/dumps/p3
dd if=/dev/block/mmcblk0p5 of=/mnt/external_sd/dumps/p5
dd if=/dev/block/mmcblk0p6 of=/mnt/external_sd/dumps/p6
dd if=/dev/block/mmcblk0p7 of=/mnt/external_sd/dumps/p7

Comments???

Agreed. Also make a CWM backup after that for convenience. After trial and error I found it does restore properly too as long as you don't forget about the recovery.img (has to be restored from acer recovery installer app)

On my thread CWM always gave checksum error for the others unfortunately.

I'll be waiting to see how you go with this. I was one of those who stupidly/ impatiently updated using the leaked acer update before understanding the need for a backup of my original. :(

Got the tablet

I got the new tablet today and have backed up the rom and put it here for all to share:

ACER_A500_1.016.04_COM_GEN1

thanks for that

what kind of backup is this ?? ( ADB or CWM )

I asked, because it's nearly 300MB bfore commiting to download

and personally, I would preferred CWM method of restoring.

P.S ... did you get any update notification afterwards ?

These are CWM created image files. Cache and data removed.
No update notification received as yet.

nevermind

downloaded this ROM, copied onto the CWM backup directory, when i try to restore using CWM, it complains about MD5 mismatch.

is this the correct way to restore?
