Nexbook AMlogic root WORK!

Because some circumstances I can't start over a new project at this time but it looks very interesting.
I have found the FAQ ... just in case you didn't see it ....

How do I extract files from an UBI/UBIFS image?

Unfortunately, at the moment there are no user-space tools which can unwrap UBI and UBIFS images. UBIFS cannot be loop-back mounted as well, because it does not work with block devices.

However, there is a hacky way to unwrap UBI/UBIFS images. But you have to make sure you have UBIFS support in your host machine. UBIFS is a relatively new file system and is not supported by all Linux distributions. But at least Fedora 11 does include it.

Let's consider a simple example. Suppose you have an ubi.img file. This is an UBI image, which contains a single UBI volume, which in turn contains UBIFS file-system. In other words, this is an image which was created using the mkfs.ubifs and ubinize tools, just like it is described in this section (the image is created for a 256MiB NAND flash with 2KiB NAND page size and which supports sub-pages). Here is what you can do:

Again, I have been through all that.

read my post here:

Bottom line the dump of system was a full NAND end to end dump. So I think where the file system ends the rest of NAND not used is junk. Somehow this is throwing off the UBIFs tools wehen you try to mount it. I always get an error and it wont mount. I even tried to truncate the dump with a hex editor and no go.

Using that info I was able to MAKE, FORMAT, and MOUNT a UBIFs system I made from scratch, so I know I am doing it correctly. But with this dump, it just wont work.

Did you see the dump I made a few posts back Finless? Have to tried that yet? If need be I can attempt another if you can supply me with the proper commands for my terminal emulator.

Next8P12-4G ROM...

OtaconEnmmerich,

Can you tell me what tool you used to create that dump? I compared my Next8P12-4G with your dump and they looked fine. However, I wanted to dump the Next7P12-8G and would like to have it in the same format as yours?

Please help with my next7P12 8G

I am a total newbie in the tablet market. I would like to root the tablet and Get a custom rom on it. My problem I cant figure out what rom I can use.! can someone please tell me what rom's are good for me. My Specs are as followed . Model Next7P 8G / Processor - ARMv7 / Serial number - YFG 111250589. If I am in the wrong section than I am sorry.

Not sure 100% but the YFG1112, if it is the AMLogic based (one can used ADB to validate), only can be rooted via a 3G Dongle hack at this point in time...

Rom Dumping

Jds, I used the tool over here.

http://android.podtwo.com/romdump/

Only thing different is that I used Terminal emulator to type out the commands instead of ADB, So it would keep the same Linux permissions and it was easier to do then dealing with ADB in Linux for me.

[Jds]

Thanks...

After comparing the ROMDUMP from my device to your device seems they are different...

Your config has Oct 10 2012, mine was Sep 17 2012.

All the MD5 sums are different mine is the AMLogic's CPU, your config file also specifies you have different sensors then mine... Now comparing the system.tar files... There are not that many differences, about 30 or so files mostly in the APK (/system/app), Framework, and, libraries (/system/lib). Thanks...

Next will be to root my Next7P12-8G then dump that and compare...

nextbook premium 8 se with Amlogic chipset

Nextbook swears that you cant charge it through the usb port. They obviously dont know there product very well. i can charge through usb or the AC adapter.

[BigBossRadio]

USB Charge How did you do that?

How did you manage to charge through the USB . I have an NextBook 8se next8p12 ARMlogic ARMv7 Processor Rev4 (v7) Android 4.0.4 ICS Board M805MC Root 20120917

Any insigth would be great

My Next8P12 is the same, Alto it's slower to charge. It DOES work, It does work better with the AC adapter tho.
Also JDS if you noticed I've got a different model then yours, Nextbook 8 SE Premium to be exact, It's expected to be a bit different compared to yours.

I also have the Next8P12-4G (from Big Lots), but also have the Next7P12-8G (from Wal-Mart)...

There are many variations of the NextBook 8se

Reading through the posts here it is clear there are many variations of the 8" Tablet Armlogic and Rockwell processor. So I did some checking to get a better understand and found this site that may well be worth taking a look at.. http://yifang.en.made-in-china.com/p...catalog-1.html
It might clear up any confusion...... I hope this helps someone out here

With your quote...

NextBook 8se next8p12 ARMlogic ARMv7 Processor Rev4 (v7) Android 4.0.4 ICS Board M805MC Root 20120917

Seems there are two OS version released mine and yours both have a 20120917 date, however, OtaconEmmerich's image was Oct 10 th 2012...

Also comparing the builds from ours to his, there are also component differences (camera libaries etc)...

So it seems NextBook/Yifang use spot buying and update on the fly to newer parts during their manufactoring processes... So even though they have one model Next8P12 it has 100 (just guessing on the number) different variations...

You are correct about that. And the link I posted seems to confirm that and so may clear up the confusion of the many variations of the image. Have you managed to get SU access yet?
