JXD Android tablets ??

you need to remove the default rubber for the d-pad and replace it with rubber from a n64 controller. its a fairly easy mod and will improved control response immensly. as far as delay goes, its related to the cpu governer and what firmware you use. the default cpu governer is slow. be warned, there is no heatpaste between the heatspreader and the cpu in the system. if you open it to replace the rubber, apply heatpaste between the spreader and the cpu for a huge stability improvement.

So I just got my S7300 about a week ago and so far I'm digging it.

One issue I've got is that the SD card slot on mine is fussy. Some days it works perfectly, other days it doesn't detect when I put a card in until I re-insert it a bunch of times.

I flashed it with Skelrom and then went to the Play store to start grabbing emulators. Getting the buttons mapped is a pain at first, but not too big of a deal once you get the hang of it. A few of the free emulators (including PCE EMU which is based off of Mednafen) are ad-supported, but that problem disappears if you've got the wifi turned off, which you should. This emulator has run everything I've thrown at it, including a dozen or so CD/SCD games.

I discovered last night that with this emu you can convert the WAV files to OGG files (lossy compression, like mp3) and update the cue sheets to replace .wav with .ogg. I used dbpoweramp and went with ~192VBR and noticed no difference in audio quality from the original format, even with quality headphones. That shrunk the CD games down tremendously, average size is now around 80MB each compared to 500-600MB.

Overall the unit feels a bit flimsy compared to my old Fire, but I'm not too worried about it. So far it's been working great. I do find my hands shifting a bit during gameplay, I think mainly because the back of the unit is flat and smooth.

the 7300 is known for its finicky sd slot. if you have an sd card larger than 16gb you should format it to fat32.  the 7300 is a very capable machine if you get one thats reasonably well made. I was unlucky enough to have got one that died. Do not leave wifi on as it murders your battery life and can cause lag and lockups on the 7300. Pay the few bucks to get the retail version of the pce emulator, its worth it.

The issue with mine seems to be a physical issue with the slot. When I click the card in, it isn't detected. But when I push the card beyond the clicking point, and hold it there, it will read the card just fine until I release my finger. I've only used small (2GB-8GB) cards with it and had similar results even after formatting.

How is the pay version of PCE.emu worth it? Does it add anything or just remove the ads? I use airplane mode while playing games (based on recommendations seen on several boards) so I don't get ads anyway.

Oddly, the free version no longer shows up when you search for it in the Play store. Still shows up in a Google search though.

[HercTNT]

the ad supported version is mostly likely an older version that can be found if you look for it on google, but no longer carried and supported on google play. To my knowledge, the google play store only carries the newer pay version with emulation fixes and updates. Making it worth it seeing as how its cheap, and has newer better features. It was not meant as a slant, just an option to play the game with wifi turned off, as wifi sucks battery life. Sucks on the sd card slot. it may very well be broken. there is a small thing you can do to make it usable, but its not perfect. You can open up the device, push the sd card in as far as it will go, then tab it with hot glue on both corners to keep it place. If the card ever needs to be removed, the glue can be pryed off at a later date. I have a dingoo a320 i had to do this with. functions just fine.

After having one for a few months, I'm kind of "meh" on it now. 

As a portable TurboDuo w Arcade Card, it's really slick.  I think if anything, it's almost worth it for that (though I wish the controller wasn't so sloppy).

But my son played it until the battery completely drained and it messed something up.  I was able to get it up and running again, but I find it hangs fairly often now and some elements just don't work like they used to.  I have a feeling if I just re-flashed it again, it'd probably fix all of my issues, but I've been waiting for NCCE 2.0 to be released (which could be anytime now).

I still use it daily, and it's tons of fun to tinker with, but it's not terribly stable and I wouldn't rely on it as a primary computing device.  Looks like NCCE 2.0 will be a nice step up. http://boards.dingoonity.org/jxd-devices/jxd-s7300-fixes-firmware-roms-thread/

The 7300 has become famous for its hardware faults. Alot of them die slowly. the biggest problem seems to revolve around its cpu. It was poorly cooled and often overheats eventually killing other stuff in the tablet. All chinese android gaming devices like this have some kinda issue, but its usually software related. Hardware wise they are generally solid. The 7300 was rushed. Now almost everyone is making them and they have improved alot in such a short time. I currently own an Iben L1 that does not seem to suffer from any of the initial problems the 7300 did.

I jumped on board with this machine recently.  I attempted to do the custom firmware update NCCE and I believe mine is now black screened (or bricked). I went through the upgrade process and everything looked great, then it asked to reboot and now it's been a black screen for hours. There are WAAY too many possible fixes for this and I've tried a couple...  Dang....

So far tried the USB firmware update, however the device simply won't appear in my 'devices' within computer management.

Then I tried (still am?) the TF card creation using the SDcardMaker.exe method... (really kind of lost with this process)

Step
1. Making a specific
TF card (Demo:
specific
TF card启动卡制作工具.avi)
Through
the SDcardMaker
to realize
it. (S7300-u-boot.bin
is necessary)
Run
SDcardMaker.exe (Demo: specific
TF card启动卡制作工具.avi)




Step
2. Forced
cleaning the Flash
1.
Copy file “aml_autoscript”
into your TF card
2.
Press “Vol +”, then press “Power” at the same time.
It
will take a
few seconds
(It should be stayed at JXD logo picture, also
possible to
appear black
screen)



3.
If there comes out some words on the screen, it shows cleaning is
successfully.

Mine is in pieces right now because the charging plug just broke off inside the unit and I'm attempting to repair it, but have you tried powering it on while holding the vol + and power buttons to get to the upgrade menu?  If you get that menu, I think there's an option to reset to the original firmware.  Then at least you should be able to start over. 

Sorry to hear this isn't working out for you.  Maybe they changed something so the custom firmware no longer works?  I hope not, unless the firmware they shipped with is better that what I got.  I know there has been at least one official upgrade since I got mine, but didn't want to reflash mine to test because I already had mine set up the way I liked it.

EDIT: Did you get the firmware from this thread? http://boards.dingoonity.org/jxd-devices/jxd-s7300-fixes-firmware-roms-thread/
That's the "official" thread and any other links could be suspect.  That's where I got mine from.  I know there's talk there about a way to trick the firmware into using an SD card as it's boot drive, but it seemed kind of complicated, so I didn't bother trying it out.

EDIT 2: If you still have problems, try posting there.  I know that the guy who created the firmware still checks in there and can probably help you out.  He's been "almost ready" to release version 2.0 for about 6 months now but hasn't due to bugfixes and life getting in the way, but he still seems fairly active there.

[_joshuaTurbo]

yep, that's where I pulled it from.  There seems to be a few issues similar to this one with the black screen.  There are even three different levels of 'bricking' that has been defined (and solved?)  I'm somewhere in the middle I think. 

I'll keep checking around and post on that thread.  Thanks man!

This may seem obvious, but have you tried resetting it? There is a pinhole to poke on one side.

Freezing/crashing is the only problem I've ever had with mine. It doesn't happen often and resetting always fixes it.

Thanks man, nothing is too obvious.  But yeah, I tried the reset hole... Still got nothing.

[_joshuaTurbo]

Apparently after all the troubleshooting done thus far I discovered it was 'deep bricked'.  There is a fix described in this very thread:

http://jxd7300.com/thread/161/reviving-s7300b-deep-brick-state?page=1&scrollTo=866

However, I managed to get a hold of their customer service and I'm just exchanging it.  Hopefully a better result next turn around. 

[roflmao]

Whew!

I'm in the middle of another vacation with my JXD and once again played through a PCE RPG and have started a couple other games.

This thing is priceless, without being so valuable that I'm afraid of losing it.
