Easybox 803A (arv752dpw22) Annex A firmware

Hi!
Does anyone have, or know how to put Annex A firmware in this router?
I tried, but it has some crc32 security check for firmware image which i dont know how to pass.
There is some info on http://sviehb.wordpress.com/2011/09/...e01-unpacking/ but it is beyond my skills.
I put together some firmware image (manualy replaced annex B image with annex A from Easybox 802 firmware), but i dont know how to spoof that crc32 cheksum.

Thanks!

P.S. I have made serial cable and also have UART access to router (and i have full flash dump) so there is no chance of bricking it. Feel free to post your suggestions!

EDIT:

I finaly got it!
If someone need annex A firmware for Easybox 803A, here it is http://www.mediafire.com/?1bi0y2ey5j1tip1

You need to shortcut R80 and bring +3.3V on the left side of R65
See on my pictures, i used wires for on/off function, because you wont be able to boot while in uart mode.
If you have and can, you can put two switches for more elegant aproach of turning uart mode off/on. I think it is safer than to solder/desolder all the time.

This is first 127KB from the whole dump. It should be a brn but i did not tested it.

how did you extract and rebuild the firmware?
Is there any tutorial?

I extracted whole flash(raw data from the flash) with brndumper.

I rebuilded the firmware image with hexeditor, bless in my case, but any hex editor you like will do the job.
SP700EX helped me on some tasks(analyze, split, checksum, extract pfs image, etc.) a lot. Author of this great tool is here among us and said he is planing to support easybox routers in future releases!
You will also need some lzma tool for packing/unpacking.
Of great help also was this blog and thread on openwrt forums.
Some other "tools" i used include: Ubuntu GNU Linux, dd, gcc, python, wine, minicom...

There is no tutorial, but maybe i could write one. Altough it is nothing special about my way of "rebuilding". It is hardly a rebuild, more likely it is "replacement" of one part of the binary, dsl firmware in this case, with another. I used dsl firmware from easybox 802 which had annex A, found here. Before that i was trying to put this one.
So you just find where dsl firmware you want to replace is in one fw, get replacement fw from other fw or allredy extracted, corect crc32 checksums and s_size value, and save. All this is done from hex editor.
I know this is not howto, but maybe it is more clear to you how i done it.

Next step for me is to put openwrt on Easybox 803A. As matter of the fact i did that too (build for eb803 is here) but i could not get dsl to work, wifi either, but didn't even bother with wifi because dsl was primary goal as i use desktop computer and lan, altough wifi would be nice for my hdd player.

Now when job is partialy done for me, i am thinking that maybe i could just replace different bits in dsl firmware, because it is not obfuscated. As it seems, start of the annex A and annex B dsl firmware is identical. Will look into this. I think that i saw some tool is using this method for changing annex A to annex B in fritz! routers, but dont hold me on that, because i am still just a regular noob and text about that was translated with google

Thank You for your fast reply!

Well openwrt/dd-wrt would be a dream, but I depend on phone functionality if the easybox...
But even with the shipped OS it's OK for me, except the limitation of the voip password length.

Yes, it is possible - for the manufacturer of the EB 803, but not for me.

Hi there...

I did something wrong and bricked my EasyBox 803A

I started to debrick it by this instruction:

Hope you can help me to use the box again, this meant not the use as paperweight.

Thanks a lot and best regards...

Hi

are you shure, you only bridged the both pin of R80
and connect the side of R65 where the description of resistor NOT is to the +3.3 V PIN of UART connector.

first time I bridged all pins by having trouble with the small wire and I got a similarly error.

Hope this helps you.
David

But how can I restore the original Bootloader, especial how can I set up the box to run with OpenWRT.
I used the tutorial on OpenWRT site. I worked up to the point were I have to install u-boot into the flash. That was the point where I bricked my EasyBox
same problem over here, got OpenWRT up and running fine on the box, then wanted to write u-boot to flash for persistent untethered booting.

...but used the wrong u-boot variant, i.e. the same 128K u-boot.bin like all those times before, when booting from RAM via brnboot, so I eventually forgot about those other 2 variants...

(however the wiki article is also kind of misleading there, when it just states "...doesn't start automatically because u-boot isn't on flash yet. To boot OpenWRT put u-boot into ram again and start it. That's it."
guess I will edit that part immediately when everything is working again )


now I did the soldering to get it in UART mode, uploaded u-boot.asc, and it was trying to boot straight through to my (previously working) OpenWRT, which however did not boot correctly since it could not access the flash in UART mode.

so now I'm stuck with that u-boot.asc running on my box, that does neither have the "loadb" or "loady" commands to upload flash data via UART, like brnboot would let me do...
it supports httpd though, which is claimed to be started on 192.168.1.1, but there's no way of reaching the web interface (AR8216 is not initialized at that point, after all).

so what to do now? could I write u-boot-bootstrap.bin to flash manually, via ascii commands? (but it seems those "mm"-like commands are for RAM only, not for flashing?)

honestly, at this moment I just want my brnboot back

but maybe someone with a deeper understanding of u-boot could help on this, thanks in advance


//edit
solved it meanwhile, using the Python script found in this post to upload everything into RAM:
https://forum.openwrt.org/viewtopic....183315#p183315

it turns out the cp command in u-boot supports both RAM and Flash writing, so I could just write my brnboot back to the bootloader afterwards :-)
