    Amlogic Next8HD8G (NX008HD8G) Modified Recovery - Stock Rom & Flashable Root

    These files are for the Amlogic Nextbook Next8HD8G (NX008HD8G).

    WARNING: These files are reported as not working on Next8HD8G tablets manufactured after August 2013. Check your serial number. If it begins YFG1013... YFG1113... or higher, do not use these files. You may try to root using Cydia Impactor instead. If you do root one of the newer tablets, please dump the ROM for the rest of us!

    Here is what you get:

    Modified Stock 3e Recovery:

    This is the stock recovery, dumped from the device, unpacked, modified to use Google Test Keys instead of Private Nextbook Keys and then repackaged for your enjoyment.

    Unzip and place the uImage_recovery file on your external SD Card. Reboot to recovery by holding Volume and Power. You won't notice any visual changes, but you can attempt to flash any .zip signed with Google Test Keys.

    Your mileage may vary. If something won't flash there is a compatibility problem between the updater-binary or updater-script and our kernel/recovery.


    Stock Rom:

    This is a close as I could get to a flashable stock rom.

    This contains a stock bootloader.img, boot.img, uImage_recovery, logo.img, and aml_logo.img dumped from the device. The system partition was also dumped from the device. I believe all of the Nextbook bloatware is here, with nothing added and NO ROOT. Everything has been packaged into an update.zip and signed with Google Test Keys. This WILL reformat System, Data and Cache. Backup any critical data before flashing.

    Place the update.zip on external SD Card and flash using the modified recovery above.


    Stock Internal SD Card:

    This is just a .zip containing the stock files from the SD Card. It includes the .pdf manuals, intro video, free public domain e-books, demo photos, etc... If you deleted this stuff and wanted it back, just unzip and copy the desired files to your internal SD Card.


    Root Package:

    This is a flashable .zip that installs the su binary and has been signed with Google Test Keys.

    Put it on your external SD Card and flash it using the modified recovery above. Then install your preference of Superuser.apk or SuperSu.apk from the Google Play store or elsewhere.


    ROM Version History:

    11-05-13 (Current)

    That should be possible. I haven't tested it though. I didn't see any point when we can boot it from SD card and I thought it would be better for most users to keep the stock recovery on their tablet in case Nextbook ever releases an official update.

    I'm currently testing CWM and TWRP builds. When I get around to releasing custom ROMs, I'll probably include a new recovery so it flashes as part of the update.zip.

    In case anyone was waiting I just tested and the custom recovery and installed the stok ROM. Worked perfect.

    It does take awhile and it's not a very visual install so be patient. When you see offset 0x3cc it is almost done.

    Thanks for the feedback!

    You are correct, the install takes a few minutes, and there aren't many screen updates during the process. This was a pretty fast and dirty mod on the recovery and I had to learn edify scripting for the updater-script along the way.

    I will try to include more on screen messages in any future releases, although I doubt that I will release any updates to the modified 3e recovery. My future development appears to headed in a different direction.

    If all goes well, I believe my next releases for the Amlogic Nextbook series will involve an EXT4 conversion with CWM and Cyangenmod built from source. After that, I'll probably work on TWRP and either an upgraded AOSP build or a Paranoid Android port.

    I don;t think it's an issue really, I think the only difference you might see is the format messages which only last a couple of seconds. When I tried to flash a custom root the animation wasn't working on the stock recovery either.

    But one note for everybody. When you try to go into recovery make sure you do not have the USB connected. If you do it forces into a hardware flash mode insteqad of recovery using power + volume +.

    Wish I had seen this thread before rooting my tablet. This is the method that I used, takes a little more effort.
    http://seclists.org/fulldisclosure/2013/Jun/115

    Are there different versions of the NX008HD8G? All the writing on the box is in Spanish and lsusb gives me 18d1:4e22 Google Inc. Nexus S
    Plus I didn't have any free e-books.

    I don't believe there are any "different" versions of the NX008HD8G. At least, I haven't heard of any.

    You are correct, the NX008HD8G did not include any free ebooks on the SD card. I copied the SD card description from my release for the Next8P12, which did have ebooks on the SD card. The NX008HD8G came with Google Play Books store, which offers many free ebooks, including all of the ones that came with the Next8P12. (They are all books in the public domain due to copyright expirations.)

    Flashable image with full ADB acess

    Standard Flashing Disclaimers Apply!! If you don't know what that means, maybe you should hold off on flashing.


    I figured I would add this here. The download link below is to a flashable "mostly stock" image for the NX008HD8G NextBook 8HD. I edited the bootimg default.prop to
    Code:
    ro.secure=0
    ro.allow.mock.location=1
    ro.debuggable=1
    This will give you full ADB access once rooted and should also allow you to use just about any of the JB compatible root utilites out there. I have tested Unlock Root, Motochopper, and Bin3ry Root Restore and they all worked.

    This flashes using ShuanMT's bootable recovery found with the instructions in the first post in this thread. Once flashed you can use Shaun's root package or one of the tools I mentioned above.

    This is "mostly" stock because I have only removed a couple of the bloat files and got rid of the stock bootanimation. I am working on a custom ROM using Shaun's recovery as well, but figured this will give people a start with a ROM that will be easier for them to theme and work with.

    Nice work. Glad to see someone else also posting some mods. Thanks again to everyone who has helped root, dump files, test, etc on the Amlogic Nextbook line.

    I would love to try your version but it seems to be having troubles downloading. Could you possibly post a mirror to a different sight. Also would it be possible to just extract the file and copy/paste the bootanimation change? Didn't this require some decompiling? Well regardless thank you for your time!

    I would be surprised if most of those "downloads" weren't all of my failed attempts. I've tried different devices and different browsers. No specific errors but just a failed download. I'll keep trying though and let you know if I'm successful. Thanks for the quick response!

    I succeeded in downloading the file so no worries about that. I'll try flashing in a little!

    Force Closing Apps

    Afher flashing the ROM then flashing root I have some apps that I was previously able to use that are incompatible with this device now on the play store. Subsequently, if I side load the apps with Titanium Backup they force close. I get same results from both Rabid ROM and ROM in OP. My question is: Could this be a result of...

    1- something missing in both ROM zips
    2- a build.prop change
    3- improper recovery
    4- something with the Root zip (I swear it wiped my external after one of the flashes)

    I will test around and see if I can't resolve this one. In the mean time I was hoping someone more experienced may be able to shed some light on the issue. Thank you!

    I haven't looked at Rabid1's ROM, but here are answers to your questions as they pertain to the files that I posted:

    1. Possibly. Both ROMs are based on a system dump from my own device. I think everything is there, but I can't promise I didn't remove something before dumping the ROM. I do know that I've had alot of incompatible apps in play store since day 1 of unboxing my tablet. Knowing Nextbook, it's possible that something changed at some point in the factory ROM.

    2. I believe my ROM contains a purely stock build.prop file. See notes in answer 1 above though.

    3. The only change to my modified 3e recovery was swapping out the key for signature verification. My stock ROM also doesn't flash the modified recovery. I thought it would be better for most people to keep the stock recovery on their device and use the modified recovery from SD card.

    4. My root package doesn't do anything but put su in /system/xbin , set permissions for /system/app and /system/xbin/su , then symlink /system/xbin/su to /system/bin/su .

    I'll take a look at Rabid1's ROM to see what changes he made.

    Also, I'm planning to release an updated stock ROM that does flash the stock recovery, because I plan to release custom ROMs that flash CWM / TWRP in the future.

    Also, I plan to release a modified stock ROM soon that will include build.prop changes for increased market compatibility, along with other modifications.

    If you have any suggested changes for either the stock ROM or a modified ROM, share you thoughts here in the thread.

    Awesome

    Thanks for the quick reply! I will just have to wait for your new releases. In the meantime I'll just keep fooling around with it. I'm thinking of copying over some files from my wife's virgin NX008HD8G and see if that resolves anything.

    As for requests I would like to add that the speaker totally sucks on this tablet so volume amplifying mods if possible would be great. At minimum some built in equalizer for media would work. Regardless, thanks for your contributions and time!

    Let me know if you find any differences between your wife's tab and your own. Any serious differences should be in the build.prop or system folder. I'm still waiting for Rabid1's ROM to download. I'll try to get some updates of some type out by next weekend. It'll depend on how much time I spend on development this week.

    I agree regarding the speaker. The speaker on the Next8P12 is MUCH better. Unfortunately, I'm afraid any volume mods would blow the tiny little speaker in the Next8HD8G. I use mine a lot for Pandora and decided to buy a cheap pair of powered speakers to use with it. Headphones also work great with it.

    Check ro.build.description and ro.build.fingerprint in the build.prop on your wife's tablet. ro.build.fingerprint is what is checked for market compatibility. Let me know what you find. Also let me know if the apps that don't work on your tablet do work on hers.

    Any future non-stock ROMS I release will report our tablets as either a Nexus or Samsung device. I'm not sure which would be best yet.
