OK by request here is my 1.4 ROM for the iBerry BT-07.
WARNING! This is one of the few ROMs that will not work on my 10G2. I have no way to test if this is a brick ROM. If it is I have made many RK29 ROMs before so I know I can fix it. You are on your own with this. Please make sure you have the stock ROM to flash back to if this one is a brick. I am pretty confident it is not but you never know since I cannot test it.
Also please read the readme inside if you have question. One thing I would like help on in the readme instructions is how to put the tablet in flash mode! I do not know how to do that for this tablet so you would be helping others if you could help me update the instructions

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
1) Full root with /system set as RW
2) SU and Superuser.apk installed and given root permissions
3) File system properly redone and blocked for NAND.
4) Market 3.4.4 installed
Whats added in 1.4 is:
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 biased
Ok well that’s it. I was working on a dual boot setup but that will have to wait for 1.5
Here is the download link for 1.4
ROM -> iBerry BT-07 version 1.4a with Google Play, by Finless (166 megs)
OK so thats it.... I hope you enjoy my new ROM. Please feel free
Again, this ROM was a combined effort from a few people and I could not have done it without them!
Oh and also....special thanks to Freaktab user Daman for an awesome boot screen and a LOW COST boot animation that will show people if the Tab is bricked or actually booting! When I say a low cost boot animation I tested it. With out it the boot time was only 4 seconds longer! But the beauty is unlike complex boot animations out there, this one gives the user feedback showing something is happening rather than wondering if it is a brick! GOOD JOB Daman and thank you!
If you the user wants to remove it, since you are rooted, just go into /system/media and delete the file bootanimation.zip. But I think you may find you like it so I personally enjoy it and will keep it
Enjoy!
