UPDATE:

Fixed my camera problem and with chainfire 3D most games work really well on this thing. For those that have sporadic camera issues make sure that you don't have the screen locked and that the screen rotates.

;) I'm crossing my fingers to get gingerbread on this device so that we can use OnLive gaming.

Also I have been messing with power profiles and am seeing better battery life in the 4+ hr range.

The charger that came with it died so I'm in the process of building another one. So more to come once I can charge this thing!

Quick question about your bluetooth. Did you actually have it working? If so have you taken apart to get the BT chip info by chance to try and recover that functionality?
[Android General] Amon_Re:
Well, I could turn it on & off, it seemed to be responding properly, was going to test some bluetooth gadgets after the firmware upgrade but alas...

I haven't taken the thing apart yet, I'm mailing back & forth with JXD at the moment to see if they can help, if that fails though I probably will take it apart.
[Android General] macsga:
The calibration needs to be done within the game. It's not device dependent. That's why other games (ie: asphalt) don't have issues. So no, I guess not. :(
[Android General] wozz9192:
Hi,

I found some threads before where it had been pulled apart and people had confirmed it was true analogue. I don't know much about the events in Android, all I know is that other people thought it was digital as well, and obviously this version android doesn't support analog. Tried searching now but can't open many forums because of firewall @ work.. If you can't find anything via google lemme know and i'll have another look because I was quite sure of it!

Cheers
[Android General] Insanetomato:
Any new info on when we can expect the update? Also your google play store instructions worked perfectly, thank you
[Android General] pogodancer:
Please explain how to resign the zip with hash key. Thanks.
[Android General] cybercod:
After a bunch of emailing back and forth with a representative from JXD, she confirmed that they do not ever intend to put out an updated firmware for the A version of this tablet. Supposedly it is because of the chipset manufacturer, which has refused to support it, which is why they made the decision to change chipset suppliers and release a new model of the tablet. She apologized a whole lot, but said there wasn't anything they could do about it, so I'm guessing it will be up to the community to figure it out.

I just figured I'd share that info, in case it was news to anyone else besides me.

The screen broke on my S7100 :'(

:crying:

Anyone know how to get a replacement? Actually it's supposed to be a gift for a friend of mine. Any replacement on Deal Extreme maybe? I got money, I just cannot wait 6 weeks for a replacement sold out S7100. Or is it still in stock somewhere? A Chinese version with the market intact.

I want to get in on the Chinese market... :silly: :victory: :angel:

I hope someone got some advice.
[Android General] butch87402:
Same here mine slid off the bed

Cheap hardware it was to be expected I suppose
[Android General] cybercod:
I'm considering selling mine for parts... how much would you pay for the screen in it?
[Android General] blaisen:
I just got the jdx s7100 for Christmas and I have downloaded 3 different roms. A supposed ice cream sandwich update, some other update, and a custom ROM called Danterom that I got from the apad forums. Each time I try to go to recovery and install these an ROM, I always get an error saying,

assert failed: getprop ("ro.product.device") == "f04ref" || getprop("ro.build.product") == "f04ref"
E:Error in /tmp/sideload/package.zip
(status 7)
Installation aborted.

What could be causing this? I read earlier in the thread that it may have something to do with the ROM being an older version than the installed ROM but this doesn't explain the ice cream sandwich update. Please help? This device looks amazing and I really want to play my old favorite games.
[Android General] CrazylegsFE:
First of all which version do you have (A,B,C) ? Because A only had 2.2,B 2.3 and C was ICS. Someone correct me if I'm wrong. I got the same message trying to install B firmware on my A model.
[Android General] macsga:
Yep. That's about it. The A model is using a different processor than B (and probably C is different from both)...

Merry Christmas & a happy New Year! :)

Bricked S7100B

Hi there,

I bricked my JXD S7100B after I tried to flash a custom rom. Now when I push the power button I only get a green light with a black screen. Windows doesn't recognize the device, anybody an idea how to fix this? It's my little nephew's device which was brand new and now he's very sad :(.

I appreciate it guys!
[Android General] sairaku:
I would suggest putting another custom ROM onto your Micro SD card. I suggest Dante's ROM or Zip's 1.5 ROM. Then try booting it into Recovery mode. If you can't get into recovery, then there is something Wrong sadly. :(
[Android General] LucaBrasi85:
I can't get into recovery mode. The device doesn't respond to anything.. only the green light turns on and thats it!:(
[Android General] sicex:
so is this device easily bricked? I have horrible luck with bricking devices hahaha. I even hard bricked a samsung vibrant! lol. Im curious about getting one yet ive seen cheaper Ly f1 knock offs with same mali but better specs other wise o.0. Is this worth getting? also does it come with any roms or emulators or do you have to get them elsewhere?
[Android General] Necromas:
Mine has a bluetooth app on it both before and after applying the latest update (for the capacitive model), but I've tried using a bluetooth switcher and I can't switch it on.

Don't have any bluetooth devices to test/use it with anyways though.
[Android General] Amon_Re:
Strange, I can't find a trace of the bluetooth app in the settigs pane. All I have are Wifi settings. (Had BT settings before the update)
[Android General] Necromas:
Doesn't show up in the settings pane, but there's a pre-installed app just named bluetooth with the bluetooth icon.

Pretty confident it doesn't have bluetooth, and it's just there because they were lazy.
[Android General] Amon_Re:
LOL. Well I would check the rom but I have no idea what I'd be looking for, where the heck are those settings panes stored anyway?

The problem is however, that after having upgraded the firmware it started to ***** about the 'efuse bt', seems to be erased and there is an option in the recovery menu to reset it but that requires a file called btmac.ef which I can't find anywhere

---------- Post added at 11:47 PM ---------- Previous post was at 11:04 PM ----------

Well, /sys/devices/platfrom/bt-dev exits...
[Android General] mengheng:
Wow, I'd buy this for the PS1 Emulation. I loved the fact that my PSP could do that, and this can do even more.
[Android General] Amon_Re:
Well I haven't actually gotten around to playing any games on it (been messing with Android itself mostly sofar) but I do like this device, for an el cheapo Chinese gadget it actually feels pretty solid. I really love this little gadget (despite having lost Bluetooth)
[Android General] Necromas:
Personally I just wanted it for N64 emulation.

But then I discovered Metal Gear Solid. Holy crap I was missing out!

The more is nice too of course, aside from the web browser and android games I've been loving the netflix app and the HDMI capabilities.

P.S. Camera app didn't work at all, and I couldn't get visionary+ to work for rooting it, until I did the update and reset to default settings/wiped all data. After doing both though the camera app works fine and I was able to root and install the market and remove the chinese apps using titanium backup.
[Android General] vinidb:
root , should i ?

Guys , i´m really sorry about my ignorance , i´m really bad when it´s about software , apps and stuff. I have ordered a jxd s7100 because i do love these oldschool games, the device was really attractive since it was also an android tablet which i can use to facebook , google , youtube etc...

But now i´m really confused , all i find in these forums are about rooting and market installation. Are these 2 things the same thing?

I mean , about the market i totally understand , it´s a source to android apps, but ...

what about this root thing? What does it mean and what it´s advantages?

Do i need to root it to get the market ? if i do root it will i lose all the factory installed emulators?

Will i need to root it to get rid all the Chinese useless apps and the tacky launcher?

I´m really sorry about not being able to help u guys back as some wise tips but if i get some real help and get my device working sharp i will sure be willing to make a paypal donation to show my appreciation ;)
[Android General] eScape2000:
If it had dual analog sticks i would by it right away!
[Android General] blokenfeffer:
Think of rooting as having an admin account on your device which gives you more power and control over the modifications you can make to the software.

Rooting will let you remove/replace some of the apps on the device that you can't normally remove. From the viewpoint of this device, it's probably the best reason why you'd want to root your device. You'll need root access if you want to replace the emulators that are installed on the S7100, because they're locked down by JXD by being system apps.

The launcher can be changed without root, as you can simply install another launcher and bypass the default launcher once you have, so root isn't really required for that. It IS requried to get rid of some of the default apps though.

Quick root method for you:

1) Download z4root and put it on the internal flash or SDcard

2) Open the pre installed AppInstaller and find z4root and go ahead and install it.

3) Launch z4root and select to permanently root your device. It'll probably power off when it's done.

Once you're rooted you should now have Superuser in your applications, when you launch that it'll ask for superuser permissions, grant them and you've confirmed that you have rooted correctly.

If you have any issues while you're rooting (such as no superuser persmissions when you've powered off), you can always root again without any issues. As soon as you apply a firmware update, you'll lose root, so you can just perform the steps above to root again.

At some point after this, superuser will say it's binary is outdated. If you're connected to WiFi when this happens, just go ahead and update SU.

If at any point anything does go wrong (though that's not likely) booting into recovery and flashing the firmware update will take you back to updated, but stock settings.

I wrote a quick guide on replacing default emulators here. Whilst this is for Gensoid, the steps in the guide can be used for the other stock emulators on the device, as the file layouts for the other emulators are similar.

Once you're up and running with root access, there are a lot of things you can do that you can't do with a rooted device. There are plenty of apps that require root access, even on the android market.

Just be careful with apps downloaded from third party websites, root access is a dangerous thing when apps are malicious. Just use sense and you'll be fine.

Enjoy!
[Android General] butch87402:
Omg guys I just got mine today its awesome..... Haven't rooted yet just can't believe all that waiting paid off Haha..... First is there an update? I have no traces of bluetooth I'm on 2.2 I love it anyways.... My lil sis loves it Haha.... Playing marvel vs capcom lol... So just use z4root and I should be good then follow the emulator replacement instructions? I just saw the market installation instructions..... Hmmmm the visionary things sounds scary.... Anyone have the firmware or rom for this device?

Is the January's 7 2012 updates newer than my current version?
[Android General] vinidb:
Thanks a lot

Hello blokenfeffer Just heard from dealextreme today, my s7100 is on the way , i will follow your guide as soon as i get it and i willm let u know how did it go =)

Thanks a looot !!:D
[Android General] butch87402:
Okay I'm having a little trouble.. The market updater application keeps on force closing..... The market is installed but certain apps I can't find them on the market is there a way to upgrade to a higher market release? Haven't tried yet emulator replacement yet will try that today....
[Android General] kblood:
I finally got mine as well. It had been in back order for a while.

But mine is the one without capacitve display, and that certainly is a huge difference from what I am used to. The LCD screen responds somewhat randomly, and it does not help that it comes with a chinese keyboard, but at least it does have english letter on the default keyboard.

It does have bluetooth though, since it was able to detect one of my bluetooth devices. I once bought the $2 plug and forget bluetooth dongle just to see what it was :)

I am considering rooting it and all that. But I want to test this Chinese layout first, or whatever it is. Its interesting seeing how different it is, and that strange app market they have. I will have to ask one of my friends who is Chinese to see what he makes of it.

It could connect, but I havent tested it much more than that. I am thinking about manually just putting APKs on it. Anyone explored the huge amounts of APKs on the DVD? Can they install on other Android devices? I have 3 Android phones. HTC Hero, Galaxy S and Galaxy S 2. And the Asus Transformer Prime Tablet. Would be nice to see if I could install some of them on one of those, just to see what would happen.
[Android General] butch87402:
Psssh lucky you I never got a cd

Also the replacement guide for the stock emulators works really well
[Android General] Amon_Re:
Whatever you do, don't update, you'll loose bluetooth. I want your rom though, if you know a way to copy it to an update.zip, lemme know, then I can restore my bluetooth ;)
[Android General] cgollner:
Didn't know about this device. I love the idea because personally I avoid some types of games for Android because I can't play it well by touching the screen.
[Android General] butch87402:
Hey man you said it was the first link but now the first 3 links are videos... I tried the other links but didn't get downloads.....
[Android General] embergabor:
Hi, can this device get to Fastboot mode? I have an other Amlogic chipset based tablet, but I was unable to do Fastboot. I have tried "adb reboot bootloader" but that just rebooted it, it did not stop at the bootloader. I want this so I can boot a custom img, just boot, not full flash (I know update is possible through recovery). Also it would make flashing or booting CWM possible.

I'll be hopefully getting the S7100 next week or so.
[Android General] kblood:
I guess I will have to root it at some point anyway. I will make a complete backup of it when I do. Well, a kernel backup anyway, and see if it will work as a rom. Well, I guess I do not have any personal apps on it expect one I am developing myself, which is going to be free anyway.
[Android General] Amon_Re:
Awesome, I'll keep an eye on this thread ;)
[Android General] cybercod:
I just got one of these from ChinaGrabber. Got the capacitive. Almost immediately followed the instructions to install English firmware and root.

I would post the link, but it won't let me as I'm too new.

All went fairly well, and I do have a version of the Market, but I'm having a helluva time getting Skype to work.

Thoughts?
[Android General] butch87402:
I got a question for the JXD S7100 owners.... Is the screen sort of blurry ike the resolution is stretch or something?

Also is there a specific English update that I don't know about?
[Android General] cybercod:
From what I gather, they posted an English firmware to their site, and quickly took it back down.

Its fairly easy to find, it came up first result for me with the search terms "JXD s7100 firmware"

I still can't post links.

But buyer beware: I've had a few freezes, and at random times, the power button will stop working and it'll be stuck either with the screen off or on depending. Hitting the reset button sorts it out, and its not a hardware issue.

Also, I'm not able to use my microphone for Skype or any apps that one would use a microphone with.

Also, all the easy downloads of game roms and whatnot are not set up in the English version.

You get the market, but it is a bit limited.

There are still a few chinese apps installed, but for the most part everything is in English, including the UI.

In short, I'm going back to the Chinese firmware to see if my microphone will work, and if the power button issue will go away.

I'm thinking they pulled it back off their site because it is broken. Perhaps they'll release another one soon, or perhaps they've decided us roundeyes can figure it out on our own. Who knows?
[Android General] butch87402:
Ah I'm on the Chinese firmware changed it to English in the settings.... Unistalled stock (apps all of em) using titanium does yours turn on the screen by itself? Launch apps by itself?

Also anyone got the network location apk?
[Android General] blokenfeffer:
There was a post regaring networklocation previously, but there were no links from the author. For ease, here's how I got mine working with maps:

Get the following files:

Google Maps 6.0.0

TiaDroid 7

1) Open the TiaDroid archive and go into update-TiaDroid7-2.2.3-2012.01.26.zip

2) Navigate to the system/app folder in the above zip and copy the NetworkLocation.apk to your device.

3) Copy the downloaded com.google.android.apps.maps-1.apk to your device.

With an installer/explorer install both, order doesn't matter. Go to settings, location & security and tick "use wireless newtorks".

Power off your device and on reboot, grant permissions to networklocation to your google account, fire up maps and confirm that it can find your location.
[Android General] iSkwerl:
I got my tablet yesterday. From what I see so far, it's not quite what I was hoping for. But it definitely has potential.

The stock launcher is slow and worthless. I do like the organization of it. I installed another launcher, which greatly increases the speed. Also, changing the wallpaper from the live wallpaper speed up the system as well, though this should be obvious.

The Chinese bloatware is annoying. I got rid of most of it (moved it to a different backup folder using ES Explorer.) The way the internal memory is set up confuses me.

I would love to see some sort of developing for this device. Even with the replacement launcher, it feels slow and clunky at times.

I'm having one issue that doesn't seem to be happening to anyone else. The screen likes to come back on by itself. At first I thought it was because I had set a screen timeout, but I turned that off and the issue is still occurring.

Overall, I'm really looking forward to see if any development is going to be done with the S7100. It has a lot of potential, but as shipped, it's a little disappointing.
[Android General] butch87402:
THANKS BLOKE

And yeah I have the same problem with the screen

What launcher do you guys recommend I'm on espier
[Android General] blokenfeffer:
The screen turning on is a known issue with this build of android, rather than this device so it pretty much happens to everyone who owns it. With varying luck you can get it to behave a little bit better, but my conclusion is to power it off when I'm not using it as it doesn't take too long to power on. Have a look at my post here.

A lot of the other peoblems are down the the Android version too. The device is snappy once you're out of the launcher and into your apps, and its benchmarks are comparible to other devices of similar speed.

I'd highly suggest replacing the stock emulators for a better experience.
[Android General] cybercod:
I switched back to the chinese firmware and the microphone works again, and I'm not having any power switch issues anymore.

I spent all day customizing it (again). Added the Market and Contacts. Currently using the Go Launcher. Seems to work very well.

Tekken 3 is a little sluggish on the built-in emulator. I noticed someone said to replace the emulators... does this make much of a difference?

Has anyone tried out the OTG USB?

I'm also curious why there are so many missing apps in the Market. Vlingo, Facebook, and ADW Launcher aren't visible to me. Is there a hardware manifest or something I need to change? Install a different market version?

Edit:

I tried the instructions here http://xdaforums.com/showthread.php?t=1133702

I even went an extra step and changed the region to US and the language to en.

Still no dice. Perhaps I did something wrong.
[Android General] iSkwerl:
Since my previous post, I have upgraded to the English firmware that was released then taken down off the JXD website. It has made everything feel nicer. Even the stock launcher is way faster now. I would keep it, as the organization for the apps and games is really nice (any alternatives to this?) but what annoys me is that you can't replace any of the apps on the main screen. I would like to replace the camera, the music player, email, facebook, and picture viewer. I tried replacing the Music.apk in the system folder with the Google Music apk, renaming that to Music.apk, but that didn't seem to work. Maybe the shortcut is pointing to somewhere else?

Also, since flashing the new firmware, the screen seems to be turning on by itself less frequently. I read somewhere that it could be a problem with the Wi-Fi being on. I haven't gone as far as to test this yet.

I can't post links, but if you type "jxd s7100 english firmware" in Google, it should be the top one. I have a capacitive screen, by the way.
[Android General] butch87402:
I had the same problem.... Applications > manage > market > clear cache and data

So is the English firmware better?
[Android General] cybercod:
The english version had buggy microphone drivers, at least on my unit. Thats a deal-breaker for me.

I have put a bit more effort into switching the various dictionaries and removing the default apps this time around, so the Chinese firmware isn't so bothersome.

I would say that the default UI is quicker on the English version, but thats just because its damn near empty. They remove many of the games and shortcuts to download them.
[Android General] cybercod:
Well, after doing the thing with build.prop last night, I had a boatload of forcecloses today on the default launcher, Go Launcher, and even in the settings. I must've really messed something up.

Starting over (again).

*sigh*

I guess I need to investigate build.prop further. Its not something to throw copy/pasta into. Apparently. ;)
[Android General] blokenfeffer:
Don't start over again to recover build.prop - it always comes with firmware upgrades, you can just drag and drop the original.
[Android General] cybercod:
Too late now, but if I had gotten that in time, what you're saying was to extract it from the firmware archive?

It was FC'ing so often, I dunno how easy it would have been to put in place, unless I used the android shell, which I'm not so hot with yet. But thanks for the tip, nonetheless.

I will say that changing the build.prop file didn't do squat as far as making more software available in the market. Or else I did it wrong. One of those two, yeah.

This is what I was trying to do.
