OK folks.... based on requests and a solid ROM dump which has been tested. I am doing a Finless 1.4 ROM for the Arnova 8G2 Dual Touch Resistive Screen. I got a ROM dump from a user that included Backup.img. Backup.img is basically a version of update.img from a tablets NAND memory. Using backup.img assures you get a CLEAN ROM dump rather than using the parts (system.img etc) that could be messed up be someone using ROOT tools.
Now I have to tell you I cannot BOOT this ROM on my Arnova 10G2! So I do not know if it is a BRICK 1.4 ROM by me. However the good news is we have a good and tested STOCK ROM now!
You can get the STOCK ROM here:

So if my ROM is a brick (which I doubt) you can recover!
Anyway below is the same stuff I talk about for my other 1.4 ROMs. Later I will do a debloat 1.5 for you all. The download link is below for Finless 1.4g 8G2 Dual Touch.

WARNING! Remove your SDCard when flashing this ROM!!! There is a risk it can be ERASED!!!
This has been a lot of work by many other people. I HAVE to give total PROPS to FreakTab user Fenice57. His first ext4 setup was not quite right. We all worked together and Fenice solved the problem by highly modifying the recovery system.
ext4 explanation:
Understand the history. After a ROM flash the recovery system formats everything. Well without a change in that it simply reformatted anything back to ext3. The ext4.ko kernel modules handled mounting an ext3 partition even if the mount command said to mount as ext4!!! It even reported it mounted as ext4!!! Go figure that one
So lot's of testing and benchmarking later..... We have a real ext4 file system!
So there was no ext4 file system to benefit from in previous work. The improved ext4 kernel modules gave a little performance add but not much. However Fenice57 worked HARD on solving this and modified the recovery system to stop the format to ext3. Sowa and myself also added in testing and showing the issues. But Fenice is the MAN! He solved it.
Fenice57... Can I just say THANK YOU! Everyone that uses my 1.4 ROM. Please also give a hand to Fenie57!
OK so what’s in this ROM 1.4
It's the same as 1.3 with a couple more tweaks on my part based on user feedback and a couple of other slim downs in code I have done to init.rc, updated lib modules, etc.
1) WiFi scan interval is changed from 15 seconds to 300. This may help some guys with battery issues. Myself, I do not have this problem but due to many asking for it, I put it in. If you want to change it back:
Use a file manager and copy out from /system the file build.prop file. Copy it on your SDCard. Then copy to PC or whatever. Edit the file and find this line:
wifi.supplicant_scan_interval=300
Just edit the 300 back to 15 and your back to stock.
2) ext4 file system.. Well I explained the work that went into this above but just to add. I have done extensive benchmarking with many tools. This does not add a huge performance increase to the overall use of the tablet. EXCEPT, and this is actually kind of benefit, Sequential Write of files to memory. Large file writes are over double what they were on ext3. Random Read and Random Write are about the same. So where you should see an increase is downloads to Tablet memory, market download and install speed, some apps that write to memory a lot, etc etc etc. Overall however, the tablet seems much faster to me but remember, I am the cooker so I am baised
