[ROM]DocHoppyRom NEXTBOOK 7 Premium*updated DocHoppyRom Full On Rootv2.0*2/14/2012

I was working on a ICS based hoppy rom. Unfortunately I just had a catastrophic screen failure, apparently when my laptop bag fell last night, it landed with enough force to shatter the screen on my nextbook! Oh well. it may be a while before I can work on anything to further the version I was working on.



FYI- Due to work, my time is very limited for working on the next version of Hoppy Rom. I apologize in advance. The company I work for is
setting up new engine test cells in China, and my self and 2 other people are main points of support! again Sorry for anything new taking so long!

DOCHOPPY HAS BEEN SIGHTED (Other than on a DAYZ server...Stay tuned.



Ok I have decided to pass along what I have been working on.

PRESENTING DOC HOPPY ROM

CRAMFS STYLE 3.0

AND

FULL ON ROOT v2.0

First you will need to decide which version of the Rom you are going to load. The CRAMFS Style version has SU but you CANNOT write to the /system directory. This is a good all around Rom for those who may need SU but do not need to write to /system.

Full On Root is just that, you have full read write to the /system and can customize the Rom to your hreats content.




HOW TO INSTALL:

TO FLASH CRAMFS STYLE 3.0 Put the UPDATE.IMG file from the Cramfstyle Folder onto your SD card, while tablet is on and follow the on screen instructions.

After running the self extracting Zip file you will have a directory containing the following folders and files.

Drivers (folder)
CramfsStyle(folder)
FullonRoot(folder)
Log(folder)
Language(folder)
Readmefirst.txt
Rkusb.log
RkusbComm.dll
Setting.ini
RK29update.exe


TO FLASH CRAMFS STYLE 3.0 Put the UPDATE.IMG file from the Cramfstyle Folder onto your SD card, while tablet is on and follow the on screen instructions.

To flash Full On ROOT, Plug your nextbook into your PC via usb cable. Turn your nextbook over and with a safety pin or something of similar size, press and hold the reset button for 2 to 3 seconds.

Run the RK29update.exe

Select your Rom files via the boxes containing the .... And navigate to the correct directory for the rom you want to install.

Insert eache file in order according to the update tool.

Clear IDB. (this is like a lowlevel format for the Rom tool:

After the Tool says OK. Select Run. This will begin to load the Rom onto your tablet. It will go through loading and then checking the Rom install.

After the Rom loads and the tool comes back with an OK, patiently wait for the tablet to reboot, and load the new ROM. If the tablet is still connected to the pc via USB when the rom boots it will show the screen allowing you to select weather or not to turn on USB storage. Press the home key and you will be given a choice of Golauncher or Rklauncher. (go lock is a screen lock program.)

Enjoy the Rom!

I used Wendal's tool to decompress the cramfs file system.

As for the /system, Because the device uses cramfs, and based on everything I have read, using Wendal's tool to decompress the file system, make the changes, and compress is the only way I can see to be able to
customize the rom for the device. The image is rooted, but after the update.img is compressed, the /system file remains read only. I tested this using root explorer, but anything requiring su works fine. But all hope may not be lost, I was reading on a chumby forum someone suggested using mkfs.jffs to make it writable, but further down it notes that you would need to change the kernel (easy enough to recompile I think), to utilize a different file system. The boot loader would also need to be modified, something I am not ready to try and tackle just yet, I think I would be bricking my nextbook pretty quickly.

It is a start and I am actually learning a lot as I go.

Any thoughts or suggestions are welcome.

Correct, root explorer does work, but due to cramfs, it does not allow you to toggle to rw from ro on the /system.

Working on taking apart apk's and customizing and rebuilding and resigning next.

Thanks for the responses!


sgtfoo : You can use Wendal's rk29xx tool to take a copy of my rom image, or the original update downloadable from nextbookusa.com, and
unpack it. You then have access to the system directory in an editable format. you can go into the system folder /system/media and replace the bootanimation.zip file with another one. Just be sure the image format is 480x 800 and that the zip file has 0% compression ratio. After you make the changes, just repack .img file via Wendal's tool and reflash.


dodoclub : Not sure why. I have a full market. You might try clearing the data and cache for the market. My market shows pretty full, I.E. I got 31050 entries when I searched for facebook in the market.

Danno65: Actually that is something I have been working on. I can get my google calendar to sync, currently I am using a calendar from the market called Jorte, which works great, how ever, googles actual calendar.apk closes unexpectedly, I am thinking it is just a version problem with the calendar, but haven't had a lot of time to follow up on it.

FYI here is the link to Wendal's tool, which makes it much easier to work on the update.img file.
