help, briked :(

I did something wrong with my tablet:

I installed a firmware for Nextbook OMA nx785qc8g, but it did not work

Now my tablet is briked

The mistake was mine, believing that my device was equal to Nextbook, but it was not.

the correct model of my device is VOXSON M8000, also known as VOXM8000FP

Quad-Core ARM Cortex A9 /1.6GHz (rk3188)

1GB RAM

8GB Internal storage (5.39 accessible)

Android 4.2 JB, Kernel 3.0.36+

8 inch IPS 1024x768 (XGA -screen)

Front Camera 0.3MP; Back 2.0MP Camera, No Flash / LED

You would guide me to find a firmware to revive my tablet?

now it's dead, so I can try different roms.

* thank you very much for your help

Cant enter flash/fastboot mode

I have tried every way to enter fastboot on this thread volume up plus power, volume down plus power, both volumes and plugging in usb and no matter what the tablet won't enter fastboot, nor will rktools recognize it. what am I doing wrong? I even tried adb commands to enter fastboot and it didn't work

edit: the problem was windows 10. this tool does not work on windows 10 in any form. switched over to an old windows 7 laptop and worked first try.
[Android General] steviori:
I was encountering similar issues as you encountered. But doing the following gave me at least a rooted NX785QC8G Nextbook.

It is now: with 4 GB storage that can be used for app installation, Android 4.4.2.

What I did: using Windows 7 SP 1 64bit (Intel i5)and a USB 2.0 port! I think the 2.0 USB port (instead of 3.0 USB port) is the key aspect.

For other info: you can search for [ ROM ] Nextbook 8 Quad Core NX785QC8G Android 4.4.2 custom root firmware (2014/07/13)

Missing Nand Flash

Dear Oma,

First of all, thank you for the ROM.

After flashing the ROM, my NAND FLash Storage went missing. Internal storage is here with a total space of 3.94gb, sd card storage is 2.51gb, and nand flash is missing. How can i fix this? Thanks! :)

Hoping that this thread is still Alive.

4.2.2 works great going to try the 4.4.2 and report back now that I have a backup installed

---------- Post added at 05:30 PM ---------- Previous post was at 04:54 PM ----------

4.4.2 didn't boot for me. Although I didn't flash the recovery partition. The cwm restored the 4.2.2 perfectly though
[Android General] perfectpitch:
Just have to say thanks so much. Got closed installed and gravity box for jb. And have everything the way I want it,
[Android General] Oma7144:
Fine.

To prettify the build one can use Xposed Framework > JB Starter Pack

A few hints:

- higher performance > disable animation scales in developer options

- battery drain > set keep wi-fi on during sleep to never

- full access to the build > enable /system rw in File Manager HD

- don't show su notifications > disable in Superuser

- Oma -
[Android General] Oma7144:
Thank you for testing!

KitKat is a selinux build. You need to flash the complete build incl. eraseIDB. EraseIDB will wipe the partition layout and the KK recovery will format the user partitions and set the right permissions.

- Oma -
[Android General] perfectpitch:
I'll try it again. Thanks for all your effort
[Android General] Oma7144:
Yes, it should work that way.

- Oma -
[Android General] perfectpitch:
Tried again still can't get 4.4.2 to boot. I erased idb then flashed the complete build and it never gets past the splash screen

Also when the phone boots into the recovery after the flash. The recovery was upside down. Again maybe I'm doing something wrong. Anyone else test this out.
[Android General] Oma7144:
Ok, the JB kernel does not have selinux on. What a pity!

However, we shall compile a kernel with selinux on. Do somebody know if Nextbook already published the kernel sources?

- Oma -
[Android General] zombiegirl2010:
Well, according to the Nextbook website, they are planning a KK update mid-july. So, wouldn't that mean the kernel has to already be prepped for KK?
[Android General] Oma7144:
So, no kernel soures published? We need simply to compile the given kernel with selinux on.

As I do not have the hadware at hand I cannot verify if the kernel has selinux on. A good indicator the kernel has selinux off is when the KK builds stucks on the kernel boot-logo. Maybe we get another try to verify this.

- Oma -
[Android General] perfectpitch:
I'd be more than happy to test a new kernel when one comes. But someone else should retest the current 4.4.2.as I said earlier its possible I did things wrong the first time I flashed it.
[Android General] Starzman1701:
No Command

Oma i have installed Nextbook 8 QC by Oma KK 4.4.2 build v1.0 and works great but when i go into recovery mode it gives me a no comand android icon and no install from sd card options or such. Any advice. Thanks for a great rom :D
[Android General] Oma7144:
Great news!

Pls flash the CWM recovery first. See instructions.txt.

- Oma -
[Android General] Starzman1701:
Is this part what you mean:

c) load recovery_CWM

and if so where do you select that in RKAndroidTool?

Thanks for your help
[Android General] Oma7144:
Yes. See post #22.

[Android General] Starzman1701:
Thanks Oma it worked great. Question maybe off topic... I have boot animations in zip file that i use on android phone. Can i install those same files on my tablet?

Thanks again for the work bro....:laugh::D:laugh:

I guess not. Upload it and I will have a look.

Can you pls post a screenshot of settings/About the tab? Many tanks!

[Android General] Starzman1701:
Sorry Oma. Meant to type 4.2..... Sorry to get hopes up.. Anyone got 4.4 working yet?

:silly:
[Android General] jfeldredge:
What turned out to be the trick to getting it into flash mode? I held down the power and volume-up buttons until the screen went black, released the power button, and continued holding down the volume-up button, for about five minutes. It showed no sign of going into a new mode, and the RKAndroid tool program never detected the presence of the tablet.
[Android General] Starzman1701:
I ended up using power - volume down. Try that
[Android General] phipps_2000:
cant get cwm to install

I can't seem to get cwm to install. Have tried several times choosing the recovery image in the image folder. The installer says completed but when booting up doesn't go into cwm just boots and reformats data and cache and boots normally. When I do reboot recovery option goes to stock recovery. Any suggestion to get cwm installed on this device?

Thanks for the ROM BTW. Looking forward to more for this tablet.

EDIT:

Found the CWM in the root of the main folder. all is well.
[Android General] perfectpitch:
Update

OMA. Just so I make sure I'm doing this right. To flash 4.4.2. I'm going to try and flash it one more time. Makeing sure I have steps right.

Connect tablet via USB to computer.

Enter fastboot mode

When nktoolkit shows connected erase idb

Wait for process to finish

Flash image 4.4.2 minus the loader

After flash tablet reboots into 4.4.2 recovery (not cwm) and formats

Format completes and reboots system.

At least in theory the next part is it boots up after 5-10 min

Enable USB debugging

Reboot into fastboot and flash cwm?

Is this process correct? If so I'll try it one more time and give answer as to whether or not this kernal boot 4.4.2

Update:

I did try it again sense no one else has posted trying to do it again. Using those following steps and it still got locked on the splash screen.
[Android General] phipps_2000:
i hope that the kinks in 4.4.2 can get worked out. thanks to perfectpitch for trying it out for us and oma of course for putting it together.

has anyone noticed their tablet shutting down when the battery says its at about 30%. mine seems to jump from about 43% to 30% then shuts down. will not not power back up until plugged in to power source then starts charging at 0%. wonder if this is a firmware issue that can be resolved. this happens in stock firmware and the oma release.
[Android General] devdude:
For me it had to be BOTH volume buttons pressed down and plug into USB port. Then the RKAndroid Tool v1.37 found the device.

Especially the 1.82GB space (in fact I wouldn't mind if you moved a bit more over there also), the 400MB or so from the original was/is totally unacceptable .. shame on Nextbook!
[Android General] devdude:
I can confirm that the KK version hangs at the Logo screen, does not even animate, just comes up and sits there.

Nextbook Upgrade

Guess I'll just have to wait for OTA upgrade since I don't have a working pc with the operating system it takes to run the tool.

About the OTA update, how does that work? I assume you cannot be on the device when it's upgrading, does it give notice that an upgrade is fixing to occur?

Maybe I'm just being stupid. But what program did you use to open the update. IMG file
[Android General] wiseman9871:
Nextbook Upgrade

I downloaded and tried to use the RKAndroid Tool that was spoke of in the posts above.
[Android General] perfectpitch:
were you on the factory image or the rooted rom that was made when you flashed. If the rom, on the tool kit did you just loaded the image up from the tool kit unchecked everything but the backup area. select the update image and flashed from there? if so maybe im just not being patient enough for first boot.lol
[Android General] wiseman9871:
Nextbook Upgrade

I didnt even try, because the way I read it, it required a pc and a operating system im not familar with and I dont have a working pc at the moment. I still have the image file and the toolkit files on my tablet but not a clue what to do with them.....lol
[Android General] perfectpitch:
Here is what I ended up doing, put stock recovery back on. Moved update.IMG to ext SD card. Booted to recovery and flasked via the normal recovery through the update part. Booted to a password screen. Then went back to recovery formated data and cache. Rebooted and all is well. Went into Dev options switched to ART. and all is working nicely minus seems I lost the internal SD card in process. Trying to get that back.
[Android General] wiseman9871:
Nextbook Upgrade

Why did you format data and cache? Now for the stupid question.....what is ART?
[Android General] perfectpitch:
I formatted data and cache because the filesystem was locking me out for some reason. after the install it was asking me for a password so I wiped it all. ART is android run time. It is replacing dalvik in the newest version of android and runs apps much smother. downside not all apps are compatible with art at this time.
[Android General] wiseman9871:
Nextbook Upgrade

Is ART in the developer options on the tablet? When you reinstalled the apps did you have issues because you are not showing and internal SD Card?
[Android General] perfectpitch:
internal sd card doesn't appear to be mounting the way I did it at the moment. Yes ART is dev options. All apps I use are compatible. I know this because i use it on my nexus 4. Im currently trying to get it rerooted then the cwm for 4.4.2 installed then I will try getting it to mount if that is indeed the problem
[Android General] wiseman9871:
Nextbook Upgrade

Ok I must be missing something, but I dont see ART anywhere in my developer options
[Android General] bat014:
ART is Android Run Time. Google created it to replace Dalvik

Sent from my Moto X!
[Android General] perfectpitch:
what you will see is the dalvik select it and it will give you an option to switch. if you do choose it . it will reboot and it will tka e a real long time to reboot this is normal.

Okay, I'm a little new to rooting tablets. I had rooted with 4.2.2 and for awhile it was fine. Now recently it likes to shut off when I open an app or something like that. Unless I have the charger plugged in. Then it stays on. But the moment I unplug it its just a matter of time before it shuts off. Should I be on 4.4.2? Being as that's what came on it? Or is it a firmware issue?
[Android General] perfectpitch:
Is it shutting off with h the same app? Have y you made any changes to the system when the problem started? I find when problems like that occur for me it's more often than not something I did messing around. But I try and tweak allot
[Android General] justinftab1488:
No its any app. Not even an app at times. I hit the windows button and it does it. Or doing something in settings after awhile. I'm going to try updating to 4.4.2 and see what happens.
[Android General] wiseman9871:
What program do I need to unzip this to the tablet to get to the instructions
[Android General] justinf1488:

That one in m not sure on. Same issue with a couple apps I use but nothing important. Any zip program from the play store should extract the zip file.

My Next book 8 is brand new, came with 4.4.2 installed.

I did not have the issue you have described, but something similar. Whenever I did not use the tablet for a day or so, I would come back and the battery would say a certain percentage. Enough of a % that I did not think it needed to be charged. Then while doing whatever the tablet would suddenly shut down and not power back on. It basically had a dead battery and did need to be charged. Just loaded Oma's KK ROM today, to early if I still have the problem.
