Amlogic Next7HD8G (NX007HD8G) Modified Recovery - Stock Rom & Flashable Root

[shaunmt]

Thank you for the reply. My device was manufactured inOctober of 2013 I had stated August, just to clarify. Is there no way to createa nandroid backup from the recovery? Like on a smartphone? Is there anything Ican do to help with this model? I am not a dev, but am willing to test or dumpor whatever maybe needed. I would love to see a custom rom and recovery forthis device. I know all you dev's work hard and not just on here, you have yourown lives, and I appreciate all your hard work. hdeg2007

A custom recovery like CWM or TWRP is required to make and restore a nandroid backup. I've been working on both, but having problems because are tablets are hard coded for UBIFS file system and neither CWM or TWRP supports UBIFS. Christian Troy managed to add UBIFS to CWM for the Ainol series of Amlogic tablets, but I haven't managed to port his changes over to the Nextbook series yet.

Keep on eye of the forums for anything you can test or otherwise help with.

Hi be sure usb debugging is enable, try using a different usb port, does your pc reconize it as a mass storage device

Got it rooted

Ok I got it to root. Now Iam wondering if there is an overclock kernel or a custom rom for this tablet? My serial# starts with YFG101. Thanks for the help.

There aren't really any custom kernels or ROMs currently available for any of the current Nextbook models. We don't have full source code available, so there isn't much possible right now.

Now that you are rooted, you can remove unwanted system apps yourself, you can also move apps to the system partition if desired and you can change the boot animation using apps from the Play Store. You can edit the buildprop file if desired. You might also take a look at third party mods, like the Xposed Framework. It uses modules that can add lots of custom features to other ROMs, many of which work on the stock Android versions used on the Nextbooks.

The boot logo's are tougher to edit. They require a dev to unpack and repack the ROM.

The partition sizes are hardcoded in the kernel. Without full source code available, I'm not sure if we'll ever be able to create a custom kernel to edit these.

It is unlikely that we'll ever see updated ROMs from eFun / Nextbook. I working on porting some alternate ROMs, but this is proving difficult because our tablets use UBIFS file system which is not commonly supported.

Keep watching for the forums for future updates!

Got it

Well that's a drag but I get it. For a dual core tablet running at 1.5ghz for $59 I cant complain. Thanks for the reply and Il be checking back.

Shaun,

Have you been using the utilities from here?

I've read the material posted at that link and found some of it to be informative.

Specifically, I've been trying to port CWM / Cyanogenmod to our devices, but the source code doesn't support the Android UBIFS utilities and I haven't yet managed to successfully modify the source code to use UBIFS instead of EXT4. I know it can be done, but I haven't had time to finish the project.

I would prefer to just convert our tablets to EXT4 for wider compatibility, but you can't simply reformat them. The partition layout, file systems and sizes are hard coded in the kernel. There is only limited source code available for the kernel and bootloader and I don't have the time or skill yet to tackle this challenge.

Thanks --

From reading that, I got the impression that the formatting is used to allow elimination of a flash chipset controller, probably for cost savings. Looks like UBIFS might be baked in at the hardware level .....

PS -- Thanks for all the work you've been doing, I've been learning a lot from reading your posts.

I think it is more of a security feature. The Ainol tablet's are the same way, but they were able to convert to EXT4 using a custom kernel.

No Luck Rooting

Bought 2 of these tabs from Newegg. One has a MFG date of May 2013 and the other Nov. 2013. I could get neither to root using the modified recovery file and root zip file via the sdcard method. It looks to me like the modified recovery never gets executed from the sdcard, but runs the stock recovery instead (install aborted error message during install of zip root file).

shaunmt: has any more work been done on the modified recovery file to work properly? If I get su finally installed, then what about busybox?

Also, the Nov. 2013 tab has a newer image, although the os version listed in (Settings, About) are the same as the May 2013 tab, yeah I know, shocking for a $60 dollar tab.

The Nov. 2013 tab is working correctly in the Google Play store, no more incompatible device on many apps. It shows as model NX007HD8G in (Settings, About). The May 2013 tab shows as NX007HD.

Android Version---------4.1.1

I bought one of these for myself just today... so i will have it sorted soon...

Mine has the august build date, which is the only build I have a copy of.

If you don't want to wait on me to get a fixed recovery posted, it should be possible to root with cydia impactor.

When you do root, Please don't make any further changes before working with me to dump the November build date ROM!

ShaunMT

P.S. I have TONS of great new stuff coming out REAL SOON!

ShaunMT: Will I need to reset the tab to a factory reset? Right now it's a fully configured tab with all my apps set up. I would want to be assured no personal data would be saved out to the ROM capture.
