Hello Ludovic,

The different partitions offsets should be listed in the line CMDLINE, after something like: 

mtdparts=rk29xxnand:0x00002000@0x00002000(misc),0x00004000@0x00004000(kernel),0x00002000@0x00008000(boot),0x00004000@0x0000A000(recovery),0x00080000@0x0000E000(system),0x00082000@0x0008E000(backup),0x0003a000@0x00110000(cache),0x00080000@0x0014a000(userdata),0x00002000@0x001ca000(kpanic),-@0x001cc000(user)

This lists:
- the MTD partition name between ()
- the partition size before the @
- the offset before @ 
 
To make the job easier, you can also use Steve's perl script on our WIKI: http://www.arctablet.com/wiki/index.php/Rksp

i don't find adb - part of the Android tools and i don't dump my tablet.

Please check the perl script, you'll need to uncomment the third line so it actually dumps the firmware.

# $DUMP=1;#Uncoment to actually dump the partitions, otherwise dry run, ie parse parameters

I don't remember of any other details to get Rksp_an10g2_dump.pl to work. I'll try to have a look later when my dev. Linux box is available.

You can try to dump the images manually using 

rkflashtool r

using my recommendations in post #2.

good evening,
I did dump my tablet lazer A101c, I saw on this site:
http://www.tracker-web-site.com/videos/lazer-a101c-auchan-comment-rooter-avec-market.html

that for the tablet must download the firmware arn10g2-23-01.zip

The unpacked file update.img has a size of 80,494,692 bytes, I want to know which file on my tablet it is:

 
FIRMWARE_VER:0.2.3
MACHINE_MODEL:AN10G2-LZ
MACHINE_ID:007
MANUFACTURER:RK29SDK
MAGIC: 0x5041524B
ATAG: 0x60000800
MACHINE: 2929
CHECK_MASK: 0x80
KERNEL_IMG: 0x60408000
COMBINATION_KEY: F,0,1
CMDLINE: console=ttyS1,115200n8n androidboot.console=ttyS1 init=/init initrd=0x62000000,0x500000
mtdparts=rk29xxnand:0x00002000@0x00002000(misc),0x00004000@0x00004000(kernel),0x00002000@0x00008000(boot),
0x00004000@0x0000A000(recovery),0x00080000@0x0000E000(system),0x00082000@0x0008E000(backup),
0x0003a000@0x00110000(cache),0x00080000@0x0014a000(userdata),0x00002000@0x001ca000(kpanic),-@0x001cc000(user)

because there is no file on my tablet that matches the size of update.img

where do I put the file update.img, is there a risk of bricked the tablet, is that we can return to its old version

Your Lazer A101c is the same product as the Arnova 10 G2 (capacitive) but has a different machine identifier (AN10G2-LZ vs AN10G2) so the normal firmware upgrade procedure with update.img can't be used (the Arnova firmware will be refused). The Lazer firmware should be very similar execpt from (I suppose) the boot logo at the start.

Having a dump from your Lazer will help you to restore it as default, could be useful if you have problems with it and need to send it for repair.

Your update image can be installed following the normal Arnova firmware update procedure: http://arnovatech.com/support/firmware.html?country=ua&lang=en&g=2

or you can use Rockchip Flashing tool that is a more low level tool that will flash it ignoring the machine identifier. You can also flash any Arnova 10 G2 firmware on your Lazer with this tool, that basically what is explain in your link.

because my system.img size is 268 435 456 bytes and the update.img is very different the size is 80 494 692 bytes.

because there were people who had bricked their tablets
and then they could not access their tablet firmware

 
I want to mount the file. img to view the file structure and i use linux.

Is there a risk to use the firmware arn10g2-23-01.zip on my tablet.

and how to go back to my old system with my dump if the tablet is bricked

 

I prefer to get all the information before I started and this is irreversible.

And I can no longer make use of the tablet.

otherwise I research how to mount the firmware see the layout of files and understand how the root is done (unlock)

If you have a proper dump of your Lazer backup image, you'll have no problem to get back to it. I can check your firmware when I have some time, probably this week end, but I cannot tell for sure. Just send the image file over (use a file upload service if needed: http://demo.ovh.com/)

 

After flashing an Arnova 10G2 firmware, you'll need to use Rockchip flashing tools to restore your Lazer firmware, because your device that will now be considered as an Arnova tablet will refuse to flash a firmware from another model (Lazer).

Also, arn10g2-23-01.zip is a rather old firmware, you have more recent firmwares from here or our Arnova 10 G2 forum.

 

Cheers.
