Custom firmware features:
- root with latest SuperSU version 1.41 (free version)

Flash with Rockchip Batch Tool version 1.7, use Restore button.
Please report any problem with this firmware, I can't verify this custom firmware works as I don't have a Yuandao Vido N90FHDRK tablet to test the custom firmware.

Downloaded the zip file, unzipped it, loaded it onto the SD card, loaded the SD card into the tablet...so far, so good. Tablet said it had found an update image, asked if I wanted it to apply the update, I said "Yes", and off it went into update world.
Image of an android with its belly cover open was displayed for a few minutes...then image of an android on its back with a big red triangle and exclamation point was displayed, and apparently the tablet is now bricked. It cycled back and forth between the N90FHDRK splash screen and the dead android image for about 15 minutes, then finally quit doing that and shut itself off. Now it won't even turn on long enough to tell me it doesn't work.
Thanks in advance for any help or info you can provide.
As post #1 says, the proper way to install the firmware is to flash with Rockchip Batch Tool version 1.7 (use Restore button).
For specific instructions to your device, other N90FHDRK users may be help you here.
Thank you, thank you, thank you! I can see now that I had climbed up on the ledge and needed to be talked down in a calm voice ... and that's what you did. I followed your instructions to the letter this time (after finding out that the magic key combo for booting into recovery mode on my tablet was volume+ and power), and it all worked perfectly. For anyone who may find this thread in the future, your link to "this forum thread" was especially helpful to me.
And yes, I'll happily donate to this website; you've already saved me more $ and frustration than a donation will cost me.

OK, I've been using this firmware for about 3 weeks now, and in general, it's a definite improvement. In particular, (1) my tablet seems a bit faster both in booting and in running; (2) it no longer crashes and powers itself down occasionally while running various apps; and (3) the battery seems to last longer, especially when the tablet is sleeping.
One thing I've noticed that wasn't (to the best of my recollection) an issue with the original firmware is the loss of the current date and time when I power the tablet down and back up. Not sure that this is something caused by the custom firmware, but it's a change, so I thought I'd mention it.
Thanks again for the custom firmware. The improvements over the installed firmware are significant and much appreciated.
i own a Visture V97HD and found a link with firmwares to download (works also with N90fhdrk, u9gt5, x900, pad9719qr, etc...). The last online was uploaded on 10/29/2013, and is dated 10/10/2013.
So this is a visture one, not online yet on visture's website.
Been installed since last night with HD display and so far, battery drain is excellent, way better than with the dragon touch firmware. Everything seems fine, quick, and stable. I just scored an average of 5800 on quadrant and 18290 on antutu's, so it's quite the same. Epic Citadel gives me a
RKBatchTool is necessary to install firmware image.
I first did restore and let the tablet reboot till the end. Then I did once again but using upgrade.

I used ZhuoDaShi-2.2.0 to root the tablet , downloaded and installed uni-init v1.0.apk to enable init.d and then installed operation killjoy 100213 RC7 through recovery.
Just to inform you of my findings.
I've tried to download your kasty-yuandao_vido-n90fhdrk-422-20130627-rooted4.zip,
from all the mirror sites as well. I keep getting a security error.
Any ideas please.
This is an old version of the firmware. We usually remove outdated firmwares to save space on our servers, please check for updated version in our forum.

I've falshed your rom "[ ROM ] Vido Yuandao N90 FHD (N90FHDRK) tablet root Android 4.2.2 custom firmware (release 2013/06/27)" into my vido N90FHDRK pad. It worked allright in the beginning. But recently the pad runs very very slow, even slower than my N90II pad. Please advise me if need to change another rom, like "kasty-cube_u9gt5-based_hyundai_play_x900_20130109-41-rooted3.zip" or a pipo M6 rom?
