You could try this not sure if it work haven't tried yet use terminal emulator
Run this first and it will list your img you want
ls -al /dev/block/platform/soc/1da4000.usfhc/by-name
dd if=/dev/block/platform/soc/1da4000.ufshc/by-name (the img you want) of=/sdcard/ (your img)
You can use this command to dump any partition updated command

If you flash the stock restore from invisiblek yes the a and b img should be the same, I think not positive not much knowledge on a and b partitions. But what I got from invisiblek's post is that is correct.

[Q] Stock AU A500

I figured since getting a replacement A500 and updating to Acer_A500_1.139.04_COM_GEN1 I would update this post with the images.
System.img - http://www.fileserve.com/file/gvemmYd
Flexrom.img - http://www.fileserve.com/file/Suq5yBG
Boot.img - http://www.fileserve.com/file/sSjqpME
Hope this helps anyone.

Here is your "knew how"... jejeje
You have to ROOT your A500 first... then use terminal emulator and type SU (this will give it Super User Access) then use the following commands:
dd if=/dev/block/mmcblk0p3 of=/sdcard/system.img
dd if=/dev/block/mmcblk0p6 of=/sdcard/flexrom.img
This will give you the actual system image (first command)
Second command gives you the partition where the update information is located.
Let me know if you need help rooting, its really easy, just remember to have your tablet in PORTRAIT not landscape or Gingerbreak will FORCE CLOSE!!!
Hope this helps... jejeje
I got a replacement A500 from JB HiFi. I will update to Acer_A500_1.139.04_COM_GEN1 then create a system.img.
This would be much appreciated! I'm in Australia, and having some issues too. Thanks again.

I'm at work today. Will hopefully get the system.img uploaded this evening, should take ~2 hours being 600MB and all. :-(
I'm not sure if the flexrom.img is needed though.
that would be appreciated as i have an issue of not being able to update after rooting and NO BACKUP

question 2 im a noob to all this so could you please let me know how ot install is
i know that it may sound like a dumb question but i have not got a clue.
I only rooted my a500 to be able to install apps to sd and that was a dissapointing move otherwise i think i may keep it stock from now on
thanking you in advance

You should be able to just copy the image onto your A500 and run the following as root: dd if=/dev/block/system-1.139.04.img of=/sdcard/mmcblk0p3
Be careful though, I honestly haven't tested the image but it should be fine.

so that means use command line and copy image onto SD card?
Sounds simple enough just gotta wait for 8 hours for download
Than again juzman very helpfull

I used the fsum utility on Windows and believe I created an MD5 checksum: 3A0AF183D5E582CBEA1D1F6BC7A61EA6
Will we need the flexrom as well when flashing this system image?
Also, this thread contains some original kernel modules: http://forum.xda-developers.com/showpost.php?p=13974214&postcount=62
Will the modules linked there be compatible with this current AU system image in the event of gps/wifi issues?
Thanks again!

Is that definitely the correct md5 checksum? I've downloaded the file twice and both times I get an md5 of 850d68aac56169b211a4913de7e4e8e9
Can anyone else confirm?

Can you say what terminal emulator to use or which is the best one to use?

I used Better Terminal Emulator (with the extensions installed). Make sure after installing the extensions (after the prompt) to go into options, select root by default, then type exit (or CTRL-D) to close the terminal so it reinitializes with all the extensions (the icon on the taskbar must be gone). Afterwards do your stuff. After flashing the system.img the tablet might reboot (show the android boot logo) and cycle. Just power down holding the button long enough, and power back on, then flash the other img.
Hi Me again
dd if=/sdcard/system.img of=/dev/block/mmcblk0p3
I did the above thingy and it just extracted mmcblk0p3 into sdcard
How do i install it ??
i cant just run it so i presume there is some kind of command or something in terminal?
Is it possible to get the flexrom too?
Thanks

Rooting ideas and discussion

I just had an idea. What if someone roots a system.img by extracting it from a kdz and then mounting it in linux copying the root files setting the permissions and then flashing that with download mode? A simple
Code:
dd if=/data/local/tmp/system.img of=/dev/block/platform/??????/by-name/system
should do the trick to flash the system.img file replacing the ?????? with the correct directory.
Just a thought.
Wouldn't you have to have read/write access in order to push the system.img?
Impossible,without root.

Already tried something similar. Requires root unless you're one of the lucky few who have such advanced knowledge of hacking bootloaders/exploits....which I unfortunately am not. LOL

Yes, look in the developer section.
It is possible to dd to partitions using download mode. The only real problem is that the root method would be huge having to include a system.img.

Additionally, you'd need a separate one for every carrier/variant.
I guess if it worked though, who cares how many we need or how big they are. Except with dd, one typo and you've got yourself a brick.

Though...wouldn't it still be able to get into download mode? I could be wrong, but that's not on the system partition from my understanding.
I'm on linux and am familiar with dd (I'm a distro-hopper and have no optical drive, so everything gets dd'ed onto usb drive).
Wouldn't we have to specify a block size on that? I know at least on linux distro, if block size isn't specified, I end up in non-boot.

Actually you are correct. The laf partition is the download mode. Flashing recovery is where we have to worry about losing download mode. (I never understood why, but at least with the G2 download mode broke when flashing custom recovery without a certain patch)

How can you confirm being able to dd to partitions using download mode? In download mode isn't the dd running from /system/bin that is mounted as ro. How could you replace /system while it is mounted and running dd from it?

linux loads commands that you are in the process of running into ram. You can even delete a file that you are running and still be able to use it until you close it. Once you close it is when the problem would occur but by that time you would already have the new file in place. Also do NOT run a
Code:
dd if=/dev/zero of=/dev/block/platform/??????/by-name/system
just skip that step otherwise you would lose the ability to dd.
Go directly for a
Code:
dd if=/data/local/tmp/system.img of=/dev/block/platform/??????/by-name/system
also to get a system.img instead of extracting from a kdz you could run
Code:
dd if=/dev/block/platform/??????/by-name/system of=/data/local/tmp/system.img

Fire HD 8 recovery

So im working on trying to get twrp up on the HD 8 but i need a backup of someones elses recovery. Its located at /dev/block/mmcblk0p7
Update please if you have root, go to adb then type adb shell and then su. after that just run this command dd if=/dev/block/mmcblk0p7 of=/storage/sdcard1/recovery.img, if you want it to go somewhere else then just change the part that says storage/sdcard1(for example if you want it to go to the device storage then just remove the 1) the recovery image should then be on your sd card. please then attach or send the recovery image to me. Thank you
Hi, please find attached the recovery file!

hey buddy, i was searching for info regarding this persist partition and i stumbled upon your post. Actually, I have a Lemax 2 and there is this camera focusing issue with nougat ROMs, and somebody was suggesting that it could be some issue with the persist partition.
So i was thinking of trying to modify or edit this persist partition.
So, can you just mention what you have done and what the above image was for?

2. go to TWRP recovery and write in the Terminal:
