sorry but, What?

no unbrick it. when I rooted it I never installed a custom rom or anything else. I just am trying to get it to work. Second boot screen is as far as it goes. I really need some expert help and your stuff and your posts are all over the place so I figured you are the man to help

The graphic drivers are loaded between the second splash screen and the boot animation. If the screen goes black and stays black after the second boot screen, you've probably got the wrong graphic drivers.

I think you are using the wrong unbrick kit / ROM for your board. This model has two different boards and the biggest difference between them is the graphic drivers.

Might be time to take a break and try again later or in the morning...

Also, make sure your CWM recovery matches the ROM you're trying to install. If you're using an unbrick kit, it also has to match the ROM... don't mix them up.

The recoveries will boot on either model, however... the recovery image and boot image both contain kernels. The kernels have the partition map hard coded inside them. The kernels have to match because the partition map used by recovery during install has to match the partition map used by the boot image during boot up.

Shaun,

I have a newer model, purchased about 2 months ago. I hosed it up originally, by rooting with the wrong files. It would get to the spinning circle screen then freeze up.

Last night, i tried your WMN SD card unbrick kit and your modded stock ROM. Fired right up. Got your new boot screen, both of them. Perfect. It was snappy and i began playing with it. Decided to reboot afterwards to test. I noticed upon reboot, it was a clean ROM again. Nothing I did was saved. So i went through and hooked up wifi, disabled some apps, etc...Rebooted again. Same thing happened. Did it a forth time, and now it is 100% dead. Wont boot at all. Nothing but a black screen. I get the power light when charging, thats it.

Any ideas? why did it get hosed?

thanks
Rick

I've yet to see one completely hosed...

Unfortunately, I don't know exactly why yours is in it's current non-booting condition.

I personally think, all of these low cost Nextbooks have flakey NAND chips...

You'll have to find a way to get to recovery and reflash it... I would suggest trying the unbrick kit again.

If you do get to recovery, wipe everything... do it TWICE! I know, it should not be necessary, but doing it twice seems to be more reliable. If you are able to flash, after flashing, wipe data / cache again. TWICE.

For some reason, data / cache and internal SD card partitions seem to get corrupted when these tablets are flashed. Anytime you have problems after flashing, first try wiping data / cache. If you problems with internal or external SD mounts, format the internal SD card. Sometimes the stock recovery seems better for this, which is one of the reasons I never install CWM internally.

Good luck... let us now how it goes...

If/when you get it flashed to a bootable state, go into settings and do a factory reset. I had todo that with the first stock rom shaun posted with the modded e3 recovery. Otherwise, all my downloaded apps disappeared, and got the tutorials, had to setup wifi, every time i restarted it.
