Word.  In the meantime, I've sent a tech support request to Arnova, and they've already replied that they've sent my request up to their engineers.

 

Fingers crossed that one of them speaks English or Engrish.

 

I'm currently running the kernel compilation for the Arnova 7 G3, I'm getting a bunch of warnings but no errors so far.

All the compilation tools (arm-eabi-*) are working fine.

Have you run the steps, as advised in the README ?

1. cd kernel

2. make sun4i_crane_defconfig ; make ; make modules

Which Ubuntu version are you running ? 32 bits or 64 bits ?

Cheers.

64 bit, but it was a fresh vanilla install.  might not have had a critical required package.

 

wondering if maybe i should try a different distro.   did you manage to yield a file?

I'm using a Debian 6.0 64 bits, I have gcc and other compiler/dev. packages but I don't think they're required, as the gcc for arm abi toolchain is supplied in the firmware source archive.

The kernel compiled successfully, but I had changed a few kernel settings, so I'll do a full rebuild with default settings for you.

Should be ready in 15 mins, I'll post the link here.

Cheers.

Here is the stock kernel compiled, I've included the image both in uncompressed and compressed formats.

So I'm attempting to rebuild a copy of my firmware now, thanks to a helpfully-supplied kernel.

 

I get an error message (see image) referencing a file that does not exist in _extract --- I can't seem to find this "oem" .fex file in multiple original source firmwares (A7 official, A7 elvish, etc.)

 

Even if I remove the line from the image.cfg file, error persists.

Any ideas?

I'm going to put up my recovery/system/boot/bootfs files online for anyone else to mess with. Link to follow.error.jpgImage Enlarger

Hi ninjaduck Thanks for your hard work, Just back of holiday and i have been playing around and managed to get an image, However it gets stuck on boot screen so back to the drawing board, i checked the config file and RSFAT16_OEM is mentioned twice

{filename = INPUT_DIR .. "_extract\\RFSFAT16_OEM_000000000000.fex", maintype = ITEM_ROOTFSFAT16, subtype = "OEM_000000000000",},

and

{filename = INPUT_DIR .. "_extract\\RFSFAT16_VOEM_00000000000.fex", maintype = ITEM_ROOTFSFAT16, subtype = "VOEM_00000000000",},

so once they are both removed the system will create the image file.

Hey guys, have been attentively reading this thread. Looks like some progress was made. Have we now got an update.img to restore our 7G3 to factory default, or at least a working CWM so we can do Nandroid backups ?

Keep up the good work guys I'm sure many people on here would thank you if we eventually get this working.Cool

EDIT: Just looked on the Arnova site and I can see they've put up an update.img for the 7G3. So this together with the kernel source being available should now help with getting CWM loaded in, right ?

There is some progress (by ninjaduck mainly) with the firmware work on the Arnova 7 G3, but I don't think anybody has managed to get a full firmware image (update.img style) than can be flashed.

The firmware available on Arnova website is for the 7b G3, which has different hardware and won't work on our 7 G3.Confused

I've been busy with other tablets but I'll try to work again on the 7 G3 in September.

When we work fine thru the firmware image building process maybe we could adapt Christian Troy CM9/CM10 made for Allwinner devices Wink

Cheers.

thanks for pointing out my mistake there admin. I thought Arnova may have put the 7G3 update.img up, but ofcourse as you pointed out I mistakenly was looking at the wrong one.

So now we either wait for Arnova to put up the firmware or we build in CWM so we can do our own.

Waiting for Arnova can take very loooong Confused there are some old devices such as the Arnova 9 G2 that still haven't any stock firmware published by Arnova.

I would suggest we keep following up:  "Can you advise WHEN firmware blah blah"

 

Nag, nag, nag.  It sucks, but sometimes it's necessary when customer service is poor.

 

Anyways, for those who have flashed a custom ROM and can't get auto-rotate or whatever other features back, I have developed an end-around method for restoring the tablet to near-stock firmware (with a few minor tweaks), tested and confirmed working.  I went to Elvish .3 for A7 and back to near-stock without a hitch.

I will be writing it up and supplying the necessary files this evening.  It's certainly not one-click, but hopefully it's a workable fallback option for those of you who have borked tablets :)

 

All credit is due to others, I just stumbled across the right half-Chinese file and made it happen.

I'd like to thank everyone who has provided information and work on this topic. It is great to have such a resource to go to. I wish I could contribute more, but unfortunate "testing" is all I'm able to offer. I recently played around with (downloaded newer versions) of Superuser and Busybox, and have messed up my perfectly good working (with Google Play - thanks again admin) 7G3, and I'm regretting the #$%^ out of it. I'm hoping a "stock firmware" will fix my problem. After uninstalling one or both of those programs, my tablet now boots to "day one" every time, retaining nothing I had set. Looking at the [Storage] it show a green bar for Internal the full way, and shows 44.1mb of apps installed. Any app I try to install tells me it can;t due to no free space. Some apps like ES File Explorer, that install to external space by default, will install. But every other app will not. Again, after a power cycle, it goes back to the "Welcome" screen as if it was day one, and everything setup and installed is gone. At least it boots right? :-) This was a direct result of me installing and uninstalling a version of SU and/or BB. I'm I wondering (hoping) that someone can tell me if a new stock ROM image (once it is made) is what I need to fix my problem? If not, I can start a new topic to discuss my problem further. Thanks again in advance for everyones contributions to these topics.
