Yup, I think the NANDS are slow in these things..

It must be that I have a buncha crap in it also.


If I do a reflash a fresh OS will boot in about 20seconds.


Tried reflashing the old kernel I was using and for some reason it's still stuck on gamepad3 splash.
I wonder If I screwed something up lol

EDIT: Got it booted again on the old kernel.. I'll try again later on I should have known better then to try and do anything with the nand before walking out the door.. but I wanted to try It out while I was out doing stuff.

Give it another go later.. Im thinking I should have wiped the cache lol

Ok update..
Reflashed the kernel, wiped cache partition.
It booted, was really terrible the first boot.. it was freezing for 30 seconds at a time.

Eventually it went to sleep.. I had it USB mounted so I could still access files, ADB seemed to still work but I could not get the screen to come back on.. so I "reboot" in adb

It booted back up but this time within about a minute I had a random reboot.
Then it never booted up .. it just kept looping at gamepad 3

hit the reset button to turn it off, turned it back on..
Again ran into a situation where the screen would not come up, dmesg in kept showing key press state changes for [play].
Hmm.. for some reason it's registering power as [play]? I guess.
I remembered I had physical button music control xposed module.. however had no problems with the old kernel.

So I rebooted, again, loaded up xposed, disable the module, reboot again.

This time so far the system seems like it was, no long freezes, it's waking up like it's suppose to.
I loaded up a movie, vsync is without question fixed.. it played great!

I do not have a HDMI enabled tv handy to check frame rate :(

Just thought I'd post the little update.. Im gonna tackle the xposed module again.. cause that I'd hate to loose it.. lets me change songs with the screen off.

Still need to check how 3D games play see if I have any GPU instability like I had a while back.
Can't say about the wifi driver refresh.. signal strength seems about the same but to early to say, Need to check throughput.. it was always pretty lousy for me in the past.


I'll get back to you guys as I test it out but the Vsync is fixed without question and that alone is a good start in my book :D


EDIT: ACK!, spoke to soon.. would not wake up again.
apparently it's not that xposed module.. maybe WC can figure this one out

<5>[ 2502.284078] iokey[play]: report ev[116] state[1]
<5>[ 2505.544061] iokey[play]: report ev[116] state[0]

System is'nt off.. it's not frozen, but screen will not come on.
it's registering power button as.. I guess [play]?

WC said they had alot of hacks to try and fix those problems on the old firmwares..

so you're best off using stock with this.
This is just the kernel so you'll need to package it up for flashing if you use batchtool.

No need to do that.  Just use the flash tool bellow to flash new kernel only instead of a whole rom.
http://boards.dingoonity.org/jxd-devices/(kernel-only)-powersleep-fix-for-jxd-s7800-(rk3188-t)/

The kernel in above link is from the special/2GB rom so just replace with the new one from here.

Can someone give me a crash course on how to use the tool

@ sandwich
Install the app Android System Info and check the screen value. It's 66Hz.

Confirmed.   66 refresh rate here too.

Dude, EDIT BUTTON.
You need to press the "Flash ROM" button.
And you can't have a custom firmware on the device, it'll just cause issues. You need to have a stock JXD one.

Select the sections you wish to dump and click RUN.   Seems pretty self-explanatory.

You dont "need" to have stock rom,  You can use a custom rom.  I am currently using a CM11 rom and have also tried it on another custom and not noticed any issues that weren't already there, although on some you "may" have issues.

Ideally though you should wait for WebClaws new rom.    Really hope he has a try at a CM11 down the road as well though :)

Great news. It also works without reducing the refresh rate from 66Hz to 60Hz. Really fantastic. Thanks for your review.
