I don't know if anyone else around here has a Next7D12...

The Next7D12F used a RockChip based board. All of the newer Nextbook models use Amlogic based boards.

I recently recieved a system dump from a Next7D12R that uses Amlogic.

Have you managed to root your tablet? If not, people have been having success with Cydia Impactor on all the newer Nextbook models.

If you can root it, I can help you dump the firmware so that I can create a stock ROM, and eventually a custom ROM for your model.

The ROM have some annoying bugs that i would like to fix.

This is how to dump the ROM from an Amlogic based Nextbook... not sure this will work the same on an RockChip based model:

The easiest way to get the system partition is to use Onandroid (Online Nandroid Backup) from the play store to create a backup. It grabs some of the other partitions as well, but not all of them.

The only way to get all of the others is to dd them. (You can't just DD system too because it is ubifs.)

Here is how use dd to dump partitions:

Do

          
cat proc/mtd

You should get output something like this:

          
dev:     size     erasesize     name 
mtd0: 00800000 00200000 "bootloader" 
mtd1: 00800000 00200000 "logo" 
mtd2: 00800000 00200000 "aml_logo" 
mtd3: 00800000 00200000 "recovery" 
mtd4: 00800000 00200000 "boot" 
mtd5: 20000000 00200000 "system" 
mtd6: 00800000 00200000 "cache" 
mtd7: 40000000 00200000 "userdata" 
mtd8: 18c00000 00200000 "NFTL_Part"

You need bootloader, logo, aml_logo, recovery, boot, and system for a full ROM.

Cache is user settings. Userdata is downloaded apps. System, cache and userdata can't be backed up properly using dd. Use Onandroid (Online Nandroid Backup) from the play store.

Don't mess with NFTL_Part!

Output file names should be as follows:

"bootloader" = bootloader.img
"logo" = logo.img
"aml_logo" = aml_logo.img
"recovery" = recovery.img
"boot" = boot.img

So your command lines for dumping should be in this format:

dd if=/dev/mtd/mtd# of=/sdcard/external_sdcard/ouputfilename

Check your mtd#'s on your device using cat proc/mtd and fill in the mtd#'s and output file #'s and enter the dd commands one line at a time.

If your cat proc/mtd output matches my device, then your lines would be:

dd if=/dev/mtd/mtd0 of=/sdcard/external_sdcard/bootloader.img 
dd if=/dev/mtd/mtd1 of=/sdcard/external_sdcard/logo.img 
dd if=/dev/mtd/mtd2 of=/sdcard/external_sdcard/aml_logo.img 
dd if=/dev/mtd/mtd3 of=/sdcard/external_sdcard/recovery.img 
dd if=/dev/mtd/mtd4 of=/sdcard/external_sdcard/boot.img

When done, copy the files and folders you dumped off your external sd card, zip them all up together in a single zip file, upload them and let me know where I can download them.
