Same Tablet and same boat

Unbrick kit not the magic pill I was hoping for to fix the brick[QUOTE=Sumphlet;152803]

it's a YFG1013 serial number so I had to use the WMN kit.

nothing I do works time to put it away! Perhaps someone will find a trick,

There could be a problem with the unbrick kit... I don't have a WMN model to test on... and no one has confirmed it working yet.

Also, you could try removing the aml_autoscript file from the external sd card... most of the time it works for me (or is even required), but sometimes it seems it isn't necessary.

Also, you could have the other board... it won't hurt at this point to try the other unbrick kit.

no cwm recovery either if u cant get in to any recovery u might have to do every thing through adb if u can get cwm try formating media then give it a try

ADB won't work unless both the bootloader and boot or recovery partition are working...

I got this to boot once just to see if it would work, but afterwards it doesn't boot anymore and now the tablet won't turn on AT ALL! Did I totally brick my tablet now where even this doesn't work??

I've experienced a similar condition before.

I've also had times when it was fully booted, but had a bad screen driver, in which case it is actually running, fully booted into android, but the screen doesn't turn on.

I was able to get mine to boot up the first time and into CWM with the unbrick kit. But since I didn't have a ROM to install I just turned it off. After that it doesn't boot at all. It used to at least show the splash screen, but now nothing at all.

No, I was able to boot up to CWM with it, but somehow my tablet got messed up in the process (I didn't evne do anything since there isn't a ROM for the WMN models yet)... and it won't boot.

it's a YFG1013 serial number so I had to use the WMN kit.

Serial numbers do not identify tablet models.... YFG1013 only means it was made by yifang in October of 2013. The other model also has YFG103 serials, because it was also made in October 2013.

In fact both tablet versions were produced at the same time for a period of at least 3 months and possibly longer.

However, in your case, if the unbrick kit worked once, then it is probably the correct one for your tablet.

After reading this, I think you need the other unbrick kit... To the best of my knowledge, all the people who installed the NXM8000ND_WM ROM on a NXM8000NBD_WMN ended up with tablets where the screen wouldn't turn on because they installed the wrong bootloader and boot image. The same thing happened to me when I tried to install the NXM8000NBD_WMN ROM on my NXM8000ND_WM tablet.

If you're tablet still had a working screen, then it probably had a different issue.

When you booted the WMN unbrick kit, I think it booted using your working stock bootloader and then the aml_autoscript wiped out your internal bootloader, boot image and recovery image.

Try the other unbrick it and if it boots, install the ROM for the NXM8000ND_WM, which is currently available.

q

were you deep bricked before you ran it the time it worked?

No, I was able to boot up to CWM with it, but somehow my tablet got messed up in the process (I didn't evne do anything since there isn't a ROM for the WMN models yet)... and it won't boot.

I apologize for the mistake on the serial number. I did know mine was a WMN because the WM ROMs I tried wouldn't work and the WMN CWM I installed previously did work. I will try it with the WM unbrick kit and see if that works. Thanks for all the help.
