OK just a little status here as I figured out that while I can make a working update.img you cannot drop it on the root directory, unplug USB, and have the recovery system update the firmware.

HOWEVER, you can use the recovery RKBatchTool which pushes the update.img.  So thats good news.  It turns out I have been making good update.img files all along (not using Wendals tool though).

So the issue "I think" is the recovery system 1.3.37.  Again "I think" it can't reformat or place the larger /system on it's own properly.  This is why it fails using the simple copy update.img to the Arnova.  Again however it will flash fine using the RKBatchTool.

The reason I think it is the recovery system is once I have used the RKBatchTool to flash my new firmware.  If I then copy update.img over to the Arnova and unplug the USB cable, the update runs but still fails to boot!  So it must be how recovery is handling my firmware for update-script vs recover-script.

I am going to depack recovery.img and have a look at what it is doing and why it doesnt seem to work.  It may also be the update-script that is part of the update.img pack.  Maybe I need to add a format command there.  Not sure.  After the holiday I will play around with this and see if I can get it working.

 

BUT the issue maybe that if you are on a stock firmware when it reboots into recovery mode and starts updating using my update.img it will always fail!  Why you ask?  Because if I fix it and it requires modification to recovery.img, you wont have my fixed recovery.img running yet on stock firmware.  You will be running the original and thus failure and it will brick your Arnova. 

This is kind of a catch 22!

Thus I may never be able to create a update.img for my firmware that you can simply copy over when you start out with stock firmware!  It may not be possible.  I "may" be able to make it work if you are already running my firmware.  We shall see.

 

Anyway the good news is I can produce a update.img and you can use the more simple RKBatchTool rather than the tool I provide with my current firmware release.

Do you all think it is worth doing it?  I mean both flash methods work and you still need the drivers installed so I am not sure there is a benefit of doing that right now?

I think that would be a good idea for less experienced people who are trying to flash this firmware but to be honest with the config file that you included it is pretty fool proof.

 

I think the most important thing here which ever way it is done is good, easy to understand tutorials and I think that they are pretty goodLaugh

If we could re-flash from the device provided we are already on your firmware will be great.

Now that the /system is rw, we can mess things that a factory reset will not revert. This will help a lot.

I played with this all day today.  It's just not going to happen.  There are 2 processes in Recovery that use scripts from the update.img file.  One script is called recovery-script and one is called update-script.  They do different things.  I have played with update-script until I was blue in the face. 

Because my firmware changes the IDB and size of IMG partitions, the update-script DOES NOT reformat IDB. Update-script also appears not to completely copy over my much larger /system.img.  So if you try to use the simple copy update.img to the device, it will never work because the changes needed are not done by the recovery updater program.

However when you flash update.img with the RKBatch tool, then on reboot the recovery system does not use the updater program but uses the recovery program.  This is why update.img does work with the RKBatch tool.

So at this point I will never be able to produce a update.img that can simply be copied over, reboot, and it installs.  Unless someone a lot smarter than I can figure it out as I maybe missing something but again I tried everything I could INCLUDING using the T760 Recovery system 1.0.  No go....

 

So I can produce a good update.img but you have to use the RKBatch Tool to flash it which requires the drivers to be installed on your PC. 

 

If you guys want my firmware in a update.img and MUST use the RKBatch tool I can make one for you all.

Have you done a factory reset with the pinhole at the side?
