I noticed Wal Mart has another new Nextbook. The model is Next7HD8G or NX007HD8G. This looks like a 7 inch version of the Next8HD8G or NX008HD8G.

Here is a link to the device at Wal Mart: (http://www.walmart.com/ip/Nextbook-NX007HD8G-with-WiFi-7-Capacitive-Touchscreen-Tablet-PC-Featuring-Android-4.1-Jelly-Bean-Operating-System/23711117)http://www.walmart.com/ip/Nextbook-NX007HD8G-with-WiFi-7-Capacitive-Touchscreen-Tablet-PC-Featuring-Android-4.1-Jelly-Bean-Operating-System/23711117 (http://www.walmart.com/ip/Nextbook-NX007HD8G-with-WiFi-7-Capacitive-Touchscreen-Tablet-PC-Featuring-Android-4.1-Jelly-Bean-Operating-System/23711117)

If anyone gets one of these, let me know and I'll help you root it. Give me a romdump and I'll make a modified 3e recovery, stock ROM and root package for it.

Did you attempt to install the Next7P12-8G ROM?

If not. DON'T!

If so, did it work????

I did try it and no it didn't work. When i put the recovery mod into the ex-sd it froze at the first boot image. and without the recovery mod it wont let me flash the stock rom. Now it freezes on the second boot image.

Good the ROM might, maybe work, but it would be a downgrade for you. Take the uImage_recovery file out of your SD Card. In fact, go ahead and delete all files you downloaded except for the kyser_root.zip.

You can still boot your tablet normally correct?

I'll be happy to help you root this model and dump the ROM for me work on. Just don't try to flash anything else in the meantime.

Awesome! You're not totally bricked then!

If you can, put your external SD card in your computer and clean off any of the ROM / Recovery files you downloaded. You certainly won't be needing them.

On your tablet, in the stock recovery, try doing a wipe/factory reset. That should hopefully get your tablet fully up and running normally again.

Please validate my assumptions:

You started with a stock Next7HD8G aka NX007HD8G.

You downloaded the modified recovery, stock ROM and root package for the Next7P12-8G.



You attempted to boot the modified recovery for the Next7P12-8G, but it failed to boot to recovery. (it should fail to boot the modified recovery, the modified recovery should not be compatible with a Next7HD8G)

After which, your tablet would not boot normally? It did boot to stock recovery once, but after doing a wipe data / factory reset it won't power on at all?

Have I missed anything? Did you try anything else between those steps? Was there anything else that you tried to flash?

It should not be possible to brick a tablet unless you've flashed an incompatible update or used some sort of USB flashing tool to erase the NAND.

Is your tablet still not powering on at all? You can't boot normally or boot to stock recovery, even with the power cord plugged in?

I have noticed with these Nextbbook they can get stuck in fel mode. My 8HD actually goes straight to it when it shuts down using the power off in the OS. Once it does this it is kind of hard to get out.

Try this.

1. Put the tablet on the charger for about an hour, just to make sure it has juice.
2. Connect the tablet to the computer via usb. Don't press any buttons on the tablet just listen for the connect sound on the PC. Check the device manager to see if anything popped up.
3. If no noise keep the tablet connected to the PC, press and hold the power button for a good 60 seconds, release and do it again. Listen for the connect sound, check the device manager for a new device.
4. If still no device try unplugging the USB. Press and hold the power button and insert the USB, look for a device to pop up M3 in the device manager.

Thanks for sharing some new ideas! Your description sounds kind of how mine acts sometimes after I try to boot a test recovery that fails.

Put your external SD card back in, with the modified recovery, and see if you can still boot recovery from SD card. If you can, at least we will have an easy way to fix it once we get the right ROM. If we can't get it boot to recovery, you'll have to learn how to either use the AML flash tool to fix it or create a rescue SD card. I don't currently know how to do either. The other alternative is to return/exchange the tablet.

Awesome it means you are not hard bricked. Before you try anything else, press and hold power until the device disappears. That way you know you are off.

I think we discussed it a little on PM about it wanting to boot into flash (fel) mode. I thought it might be your or my rom or the recovery or some combination, but it looks like it is just a design flaw in the tablet themselves.


If we can't get somebody to provide a ROM dump by next week maybe, I can pick one up from Walmart just to dump.

I thought about doing the same, but I don't have the extra cash for another toy right now. I also thought about picking one up, dumping it and returning it, but I'm planning to exchange my Next8HD8G and I think they limit returns/exchanges these days.

I am under the impression that it can flash individual partitions or everything, but I don't know what format the files need to be in. It should also be able to format and partition the NAND if necessary, but again I don't know how to configure or use it.

You're tablet is not currently booting anything, correct? No system, no stock recovery, no SD card recovery, nothing?

Does ADB work? does the backlight even come on?

after searching high and low for roms and firmware. i came across one thread that mentions unsoldering and resoldering the battery. so i opened up the tablet to see if the pictures were similar. and discovered on the battery a sticker that says yifang m7000nd . could i possibly use the firmware marked for the chinese model?

A large number of these cheap tablets are actually made by Yifang and resold under many different names. Have you found another tablet that you think is the same? A lot of us here would like to know about, as the ROMs are often interchangeable, assuming the hardware is identical.

I'm sure several of us would also like to know how the dissasembly went and photos would be nice too! Was the case easy to open? I've never tried it on any of mine.

CAPS REALLY AREN'T NECESSARY...

There are no official updates available. Neither the vendor nor the manufacturer even provide a copy of the original firmware.

If you've got a brand new tablet and haven't yet tried to flash anything, and your WiFi doesn't work, then you very well may have a defective device.

If you have flashed something that didn't work right, then you might want to try the files available here:

http://www.freaktab.com/showthread.php?7011-Amlogic-Next7P12-8G-Modified-Recovery-Stock-Rom-amp-Flashable-Root (http://www.freaktab.com/showthread.php?7011-Amlogic-Next7P12-8G-Modified-Recovery-Stock-Rom-amp-Flashable-Root)

The ROM posted there offers no new features or fixes. It is simply a copy of the original ROM dumped from a working device. The modified recovery is just like the stock recovery only it allows you install packages signed with Google test keys instead of Nextbook keys. The root package will root the tablet.

Yeah... you'll be wanting an external SD card. Don't skimp on a cheap one either... they tend to wear out very fast. Spend a little more for a name brand one, rated class 10. A name brand one can probably be expected to outlive the device you buy it for.

I got a 32GB Class 10 SanDisk brand micro SD card from Amazon. I think I paid around $30 for it.

You need to download a terminal app to type those commands into.

You need to go to settings in Online Nandroid Backup and install the onandroid script and mkyaffs2image.

You'll also need to change the backup location to your external SD card, and select save Yaffs2 as Tar.

Cydia Impactor rooted my NX007HD8G on the first try. But then I foolishly fiddled with some system files and ended up with the left 60% of the screen black. It still responds to touches, but I have to guess what I'm touching. Factory Reset dumped all my apps, but didn't affect the display. I sure could use a flashable stock ROM package!

It will be the same format as I posted for the other models, a modified recovery, a non-root stock rom, and a root patch that can be flashed by itself.

The recovery screen is titled "Android system recovery <3e>". (I think this is normal.) I select EXT, sdcard, and the mod recovery package. The display shows:

-- Install /sdcard ...
Finding update package...
Opening update package...
Verifying update package...
Installation aborted.

The robot falls over on his back with a red triangle with a black exclamation point on his chest.

I assume my tablet isn't accepting the package signing, but have no clue why that might be the case. I downloaded the file again in case my first try was corrupted, but no change.

What else can I try?

Thanks.

Yes, the modified recovery says "Android system recovery <3e>" just like the stock recovery, but you DO NOT flash the modified recovery, you just unzip it and place the uImage_recovery file on the top level of your external SD card. With it placed on your external SD card, the tablet will automatically use it instead of the stock internal recovery when you hold volume and power to boot to recovery.

Then if you try to flash the ROM or the Root patch, it won't fail the signature verification anymore.

"If all else fails, read the directions!" I used to tell my kids that. Anyway, I tried it the way I was supposed to, and it won't boot to the mod recovery. The tablet freezes at the first boot image. Did I also miss something about the sd card format? I did a full format in Windows 7 to FAT32 with 4096B allocation unit, put nothing but the mod recovery image on the card, and tried to boot it. No luck. It did boot to stock recovery with the blank sd card installed. During boot (normal or stock recovery) there's a subtle change in screen brightness a few seconds after the image first comes up. With the mod recovery on the sd card, the image stays at the initial brightness level. That tells me it's freezing very early in the process. Earlier in this thread, Jeremey989 was also unable to boot to the mod recovery, but he had other issues as well. I can still do a normal boot, but with the half black screen.

Your card should be formatted ok as is. Can you access your external SD card from within Android?

Not sure why it won't boot to the modified recovery. Unfortunately, I can't do much troubleshooting without the tablet.

It sounds like there might be a problem with the kernel. What is the kernel version reported under About This Tablet in Settings?

I don't know what Jeremey989 was using, but it wasn't my recovery for the Next7HD8G, because I just posted it this week.

The kernel no. is 3.0.8 and the build is JRO03C.v008
The SD card works fine both read and write in my desktop PC (in an adapter) and in a tablet that's a twin of the one that's giving me trouble. I can't be absolutely sure it works in the problem tablet because I can't see enough of the display to operate the software after a normal boot.

Jim, am I correct that you previously flashed a ROM that was not compatible with your tablet?

Jim K
11-13-2013, 07:43 AM
No, I never flashed anything; that was Jeremey that said he flashed the wrong ROM. I made the mistake of directly modifying some files in the system folder rather than flashing changes.

I just put the sd card in the working twin to my problem tablet and tried to boot it to the mod recovery. It behaves exactly the same way. No shift in display brightness, and locks up on the boot screen. So there must be a fault in the recovery package.

Could it be the archive process? Is it safe to assume it was archived in an uncompressed format? I used WinRAR to unpack it, and the file size was the same as the zip file (3859KB).

It is an uncompressed zip archive. Assuming, you unzipped the modified recovery and put just uImage_recovery on the external SD card, along with the still zipped up ROM and/or root package, the problem is going to be related to kernel compatibility, the recovery ramdisk, or the way they were packaged to create the uImage_recovery image.

I'll see if I can boot the recovery image for your tablet on my Next8HD8G when I get a chance. The hardware is similar enough that it should boot, although I may not get any screen display due to the screen size difference. If that's the case, I can write a script to test if the recovery is actually running.

After my false start, I'm sure I've set up the card correctly.

FYI the 7 inch model's display is 1024x600 pixels and the 8 inch is 1024x768. Don't know if that's useful info.

I really appreciate your time and trouble.

FYI. The modified recovery won't boot on my Next8HD8G either... it fails and falls back to the stock internal recovery instead. I'll have to work on it and post a revised version. The good news is I should be able to test the recovery on my tablet.

I'm absolutely certain that I downloaded the mod recovery package from the same page as the ROM file, but I just noticed I had the Next7P12 recovery file instead. I downloaded it again from the same link, and this time got the NX007 package. Now I can boot to recovery, but it must be to stock (just like your NX008) since the ROM install aborts during verification. I don't see any indication that the sdcard recovery failed; it just comes up on the recovery page the same as without the sdcard. The progress bar gets to about 1/2 inch long during verification before the install aborts. Just to confirm, the file I have now is 4,178,878 bytes, dated Nov 10, 2013.

I don't know anyone who has had any luck with the amlogic usb burning tool, expect maybe a few of the ainol guys over at slatedroid. Everyone else who has tried to use it has only bricked their tablets.

If I had to guess, whatever ROM was included in the download with it is not for a Nextbook. It is most likely for an Ainol tablet. I haven't been able to get any of the ainol ROMs to work on Nextbooks.

I'm pretty sure this model doesn't have bluetooth. The 8 inch version doesn't.

The 8 inch version is 1024 x 720. Not sure if the 7 inch is the same.

eFun / Nextbook is horrible about changing hardware and inaccurately updating packaging and manuals or not updating them at all.

eFun / Nextbook hasn't provided updates for any tablets in over a year. I wouldn't count on ever seeing another one and definitely not an android version update. This is true of most of the other budget tablet vendors also. They buy the same cheap tablet models from Yifang Digital, slop together a ROM and ship them out then don't offer any support or updates. They basically assume you'll pass the tablet to your kid and upgrade to a newer model with a newer system version on it.

The specs on the newegg website match my NX007HD8G. The screen is 1024 x 600. It does NOT have either bluetooth or GPS. The documentation doesn't mention it either way, but it does support USB host with an adapter (at least my wireless mouse and a flash drive work). I couldn't find this model on the Yifang website. The Nextbookusa website says it won't charge through the USB port, but it really will, just very slowly; 500 ma from USB vs 2 amps from the AC wall charger.

This is the webpage for Yifang Webpage - http://www.yifangdigital.com/product/M7000NBD.aspx

which is the same model number as Newegg.com

I didn't see Bluetooth nor gps in the owners manual. But I did see the resolution conflict.

Do you by chance have a hard copy of the manual ?

Thanks for your guys post !! Glad to find a site already messing with this product.

Jim K
12-07-2013, 08:23 AM
I think the Newegg website has an incorrect reference to the M7000NBD. The M7000NBD is very similar to the NX007, but has some significant differences, i.e. Bluetooth and Android 4.2. Everything on the Newegg listing except the M7000 reference, including the pictures, seems to match the NX007. Google Play identifies my Nextbook tablet as a Yifang NX007, not an M7000...

I have both hard copy and pdf versions of the owner's manual.

12-07-2013, 09:19 AM
I agree newegg has not represented this product with the correct model number. It seems everyone has been confused by this on that site.

Good thing is if you can actually get through on live chat and complain about product model and shipping delay they will give you a 10.00 credit.

so you either can order this and wait it out for 49.99 or you can order it and wait till they credit you 10.00 and then cancel your order for a FREE 10.00.

That is the build date of the ROM.

The manufacture date is on the packaging and may be later than the build date of the ROM.

The newest ROM build I currently have for this model is from 8/12/13.

I have only rooted, and loaded utilities to try and back up this nextbook. I finaly went through all your steps and got the ROM dump.

I will be glad to share it with you if you don't already have it.

By the way, I was totaly honest with Nextbook, told them what I did, they said if their was no physical dammage it would still be covered. Later I got an email saying that if I do it again, it will not be coverd. Glad they stood behind what they first told me, and glad I was honest. My thoughts, if you have a bricked unit, it cant hurt to send it in if it is less than a year old. In USA, I used BOOK rate, and boxed it very nice and solid. Less than $4.00 to ship it.
