Rough GingerComb port guide 4 NextBook Premium 7
A few days ago I stumbled upon this thread and figured why not try and port this over my nextbook premium7 S/N 0911.
So first off all credit should go to Finless for making these groundbreaking rom components that we're gonna be using.
Alright so my nextbook can boot the 0911-v1.4, 1211-v.1.5, and 0512ics roms (so good chance others can boot this as well I also haven't tested any other roms so this might work with the 1111, and 1011 too).
Alright the files I used was The Finless's Cube U9 GT-2 gingerComb v1.5 rom , Finless's Nextbook P7 1211 rom, Finless's Arnova 7bG2 GingerComb v2.1 beta-2, Petrus's Reboot App, and these new parameter files.zip
What has been tested and works at this time of posting.
-wifi
-Sound
-tilt controls and orientation changing
-soft touch buttons
-power button
-wifi location services
-CWM Works great clean backup and restore -Its awesome Thanks Finless!
Stuff that dosen't work or is wonky working that I've discover so far.
-Credit page is displayed as hash. The native resloution is to big for our puny screens lol.
-battery image displays a ? on taskbar. It does display the percentage number if clicked on. (Finless has a fix for the Arnova's So I'll check with him and see if I can duplicate it for our nextbooks)
-No volume controls on desktop :/ (you can edit the available volume for events in the sounds column in the setting menu. media is for apps, music, video, etc.. So this is the one your gonna mess with. If your gonna get an app to adjust volume I recommend slider widget from the play market also button savior only affects ringtone volume so it doesn't help here.)
-CWM Doesn't mount my sdcard on boot. You have to manually mount it and if it doesn't mount the first time Remove the sdcard from the tablet than put it back in and hit mount it should work now (my sdcard might be corrupted though)
Steps:
1.So just rename/delete the kernal.img that comes with the Cubes rom's image folder.
2.Copy the Nextbooks rom's kernal.img into the Cubes rom's image folder.
~~CWM Optional Step~~
----Rename/delete the Cubes rom's recovery.img
----Copy the Arnovas rom's recovery.img to the Cubes rom's image folder.
3.Download the zip file below or above Unzip it and place the corresponding new parameter file into the cubes rom's image folder replacing the stock parameter file.
---new parameter files.zip
4.Your ready to flash your tablet Remember to EraseIDB.
~~~First Time Flash Step~~ Follow the read-me text file in the Nextbook rom to install the correct driver to flash your tablet
5.On the first Boot-up after flashing it takes about 1 1/2 minutes to get to the desktop (Non-CWM its about the same with CWM but you get held up by user response time).
~Approximate: Time breakdown for first boot-up~
00-14 seconds total 14 seconds: to format cache to ext4 and reboot
14-53 seconds total 39 seconds: The credit page will look corrupt/hashed dont worry about this its normal I'll explain below later. This goes till you get to the loading screen.
53-78 seconds total 25 seconds: The animated loading screen to desktop
6. AppInjector by Petrus you can use the package.zip from cube, nextbook, and arnova(These one suck tho
) to install the apps back except (Stock Browser, calculator, 3dgallery/gallery, stock music player, stock video player I'll explain below later)
-Note: if you install any app developed specifically for the nextbook like Astro or Task Killer it will force close when you push it to the background (astro & task killer) I'll explain below
This rom does come with added bloat considering we don't have a camera or microphone so it needs re-debloating lol.
Alright so post your results and any problems you might have.
Notes-
Why we need the new parameter file and what is actually changed. Basically this is needed because the cubes userdata partition is 2x(2gb) nextbooks (1gb) (they have more memory in their device). The userdata is shrunk to 1gb like the 1211 image. Then kpanic, system(Which is bigger also), and user partitions are correctly placed 1gb less to fit in our memory. For CWM Version the same is done but every partition after recovery is moved back 4000 block(about 4 mb)
Why the credit page is corrupt/hashed this is because only the kernal has loaded and the credit page is not the right resolution for the screen so what its rendering is the image being overlaped and nudged this dosen't hurt anything just looks awful.
Why we can't load the stock apps like browser, etc.. . These app apparently need the kernal and library files to match to load correctly (if injected they just close right after opening, although you can try to do a factory reset to format dalvik cache to get them to work but it like a dice throw, I got it to work once the rest were 3 minute boot ups and force closes) . If the cubes version is cooked in to the rom then they work just fine
(Don't try with the nextbook versions you get the same results as if you injected them).
why apps made for nextbook force close when pushed to the background. Alright what that means is when you open an app and then hit the home key they're still in the background running keeping the stuff you were looking at alive. Well Astro and task killer cant figure out or dosen't like how this hybrids-system/honeycombs (Snapshot.apk) handles this switch and they force close as a result.
I'll make a quick guide for mounting system.img and adding the stock browser, etc.. later . Also a short list to debloat since your already in system.img.

(Probably had a corrupted sdcard tho I've formatted it since then for your release
