UPDATES

04/02/2013: Patch_Xsample_2.1.rar

Mirror Mega

Change log:

Tincore KeyMapper

• AutoProfiles. By enabling this option, the KeyMapper automatically load profiles, depending on the application that is running in the foreground.
  
• AXIS Inversion Selection
  
• Dialogos selection list of options
  
• Elimination of unnecessary controls
  
• UI Enhancements (simpler interface)
  
• Better integration Holo
  
• Scalable Icons
  
• Component Selection pressing physical controls
  
• Renaming profiles
  
• Exporting profiles *
  
• Importing profiles *
  

* With these options opens the possibility to share applications among users profiles.

Driver Tincore

• Acceleration of the driver
  
• AXES Inversion
  
• Accelerometer support *
  
• Fixed some bugs
  
• Support for specific calibration D-PAD **
  
• Added hot-key [VOL-] & [L2] to reset current profile ***
  

* Now you can assign horizontal or vertical tilt to one of the axes of the sticks. With this option, you can play many N64 or PSX titles (preferably on emulators that support analog), and the inclination to use the console to control the action in games. Example: Mario Kart 64 may play a "Wiimote Style" or Forsaken, can be controlled by tilting the tablet.

** The D-PAD, as already explained is analog, but which behaves as digital.
There is a problem with the D-PAD and their center (neutral position) is shifted to the right, so the analog calibration can influence the response of the D-PAD, for example, that in some games and emulators respond correctly to one side, usually to the left.

To avoid this, in games / emulators that specifically use a d-pad instead of analog, recalibrate the driver is suggested to use the D-pad as the main entrance. To do this, simply open the tool and select "Calibrate" in the Stick 0, and use the D-PAD to calibrate the device.

Note: The calibration is stored in the profile of the game, so it will not affect other profiles created with KeyMapper.

*** This combo is useful if you experiment problems or get stucked with your current keymapper layout. You can use in any time to reset profile to values.

Requirements

Having installed the rom-SXELROM TheXSample v2.0 before installing this patch.

About this article

This article is a summarized version and only contains the most relevant features..

To read the full article check the previous link


Features



(SXELROM beta, showing some features)

Only features present
at the time of the writing of this review are listed.

(Separate external and internal mount points)

• Based on Skelrom v1.0 for JXDS7300B, private 1.4stock firmware sources and JXD 1.5. Includes all Skelrom and last official firmware fixes.
  
• Clean code. Official sources only. No alien code.
  
• New mount points. Now internal and external mount points are at the same level in the filesystem and not one inside the other. Swap is easier.
  
• Deep sleep improvements. WiFi disable when sleep saves a lot of battery.
  
• New Kernel features by Skelton andTincore (check Kernel chapter)
  
• New specific governors tailored to device hardware. Specially new "ondemand" scores more than 10000 Antutu points with console processor running at 1.3GHz (No cpu stress needed)
  
• New "ondemand" governor allows cooler execution.
  
• 50Hz to 60Hz screen fix, The same that we suggested JXD to incorporate in his 1.5 firmware (Check screen refresh note)
  
• New Tincore input kernel driver. It provides lower input lag and lots of extra configuration options to support new sticks and buttons operation modes.
  
• "Tincore Keymapper", UI Mapping tool to configure specific input kernel driver options (check Tincore Keymapper chapter)
  

About new Kernel

This firmware's kernel has been created using JXD 1.4 sources. Those sources, whith some small chanes, have been released as JXD 1.5 firmware.

(new governors added)

More important kernel feautres:

• Chanes in CPU and voltage to improve temperature and stability.
  
• Support CIFS/NFS for seamless net shares filesystem mount.
  
• I/O schedulers and NAND optimizations. Improve read/write operations and memory access.
  
• Mali driver optimizations to speed up 2D and increase graphical memory cache buffer.
  

(Antutu Benchmark result with new firmware improvements, governor “ondemand” and 1.32GHz. Reaching 10000 points which is a bit better than 1.5GHz with performance governor)

About new input kernel driver: Tincore Driver

Tincore provided a new kernel driver to improve latency and support many missing features in original drivers.

(Keymapper, with new features like pointer mode)

Driver improves response times because it is more optimal and faster than the original. This reduces input lag

New driver enables key events for all sticks when mapping tool is disabled, This allows to use right stick as a key pressing digital stick. Because of this it can be used by emulators and games that can be controlled with keyboard.



(Showing some of the new features of the Tincore's Driver)

Keymapper tool features

(Keymapper using original JXD driver)

The new mapping tool supports both JXD driver and, naturally, the new Tincore driver.

The tool supports multiple stick modes (split/combined/pointer...) and allows to define where is the screen pressed when a button or stick is operated.

The tool supports profile save and restore and portrait mode.

Because of its backwards compatibility the tool by itself is a good replacement for the JXD mapping tool. Ley profile support is already a great addition.

Thanks to:

This firmware has been possible thanks to the work of several persons. All valuable contributions have been in the form of coding, suggestions, testing...

Thanks go to Tincore, Skelton, Christian Troy, fun_, fuser-invent, LomaX, Namco69, Yoshi41, Deen0X and more.

Also thanks to web shops Willgoo y Zococity that provided testing devices that allowed tetst and feedback for the team.

(Gracias a que pude contar con mas de una consola, me fué posible realizar una serie de pruebas en paralelo para obtener información útil que se utilizó en el desarrollo de algunas de las características del firmware)

I also want to give special thanks to the couples (wives, etc) several of whom have been working on this project, that it takes patience and an understanding that we do this because we love, and we want to share it with more people.

I hope this project is the starting point for more projects of the same type, which are extremely rich in both technical knowledge in general, but especially on a personal level, because in my case I meet interesting people, who always is rewarding and I hope to keep in touch. ^_^

Zalu2!

Deen0X / TheXSample

Wow ! Impressive !

Thanks Deen0X ! And welcome Here !

The Antutu Benchmark result is amazing

Welcome and Thanks Deen0X.
Note: I am following your youtube channel, it is awesome!

Thanks guys... hope you found interesting and useful my articles that i want to post here from now.

Zalu2!

Yes of course ! you can post here when you want you are always welcome !

I am very happy to see this finally released.

bonjour à tous , j'ai reçu ma tablette cette semaine et il y a dessus la Version officielle 1.5 d’installé sur ma jxd 7300, est ce que je dois installer cette version sur ma tablette ou aucun intérêt?

Salut, oui je te conseille cette version car j'avais des problèmes en sortie de veille avec la rom 1.5 officielle, celle-ci est mieux, plus stable, et l'outil de mappage (tincore) est mieux...
Par contre je viens juste de m'acheter un câble mini hdmi et ça saute sur ma télé, de temps en temps écran noir et hop ça revient, parfois toutes les 15 secondes... Je ne sais pas si ce problème est connu, si ça vient de la rom ?

ok, je te remercie

hdmi problems are related to quality of hdmi cable.

i posted a patch for nova3 game on my blog. if we need to post more fixes,all there will be on my blog, then keep an eye on it for updates (sorry, i try to mantain many forums, but is a mad task try to post the same update on all of them, and i prefer to centralize all updates in one single article)

hope you found useful this rom and to improve the experience with this device.

Zalu2!

Bonjour tout le monde!

Peut être pourriez vous m'aider.
J'ai fait l'acquisition de la JXDS7300B mais n’étant pas très familier d'android, j'ai toutes la peine du monde à installer cette rom custom.
En effet j'ai beau extraire le .rar de la rom dans la racine de la carte:

Allumer la console en mode recovry:

Et essayer tant bien que mal de naviguer dans les menus:

Toujours aucune traces des fichiers de la rom

Merci d'avance.

put all these files on the root of your sdcard
insert this on the device powered off
press and keep VOL+, and power on
keep pressing VOL+
the system automatically start the update (you don´t need to select nothing)

Formate ta MicroSD en FAT =)

L'installation s'est fait sans aucun problème.
Par,contre petite question, j'ai lu dans l'article qu'il propose un patch, donc une fois installé la v1.0,le patch on le met ou?

There are few patches, some of them optionals.

CPU speed and sdcard swap patch. this is optional.
with CPU speed, you change tue default cpu speed to higher or lower GHz. By default, the device runs at 1.32GHz, but you can change this using SetCPU or similar program, and can increase or decrease the speed, but when restart, the scpeed is set to 1.32GHz again (and you can establish that SetCPU increase again on each boot)

but with other kernels, you can simply define the default speed of your CPU.

I suggest to try the default config, before using any other speed patch, specially if you want to overclock the cpu.

The other kind of patch are related to some fixes for the system. For now, we get some reports that Nova3 is not running with the default config (images freezes when game starts). There is a patch that solve this. If you have problems with some game, i suggest to you to apply this patch on your system.

Zalu2!

thanks you

thanks you!
Merci les gars!
En effet c’était juste le système de fichier à changer.

Pas moyen d'accéder à la SD sous windows 7 , j'ai coché /décoché USB debugging ...

y a t il un driver particulier à installer ?

Ben, il me semble qu il a installé les driver automatiquement...

Hi Deen0x, thanks for this release, but I want to report a big issue, the micro stuttering is here again the same as JXD OFW 1.0, 1.1 and 1.3.

After a sleep exit, the sutter is here like older JXD OFW's.

The JXD OFW 1.5 don't have this issue, and the NCCE 1.0 not too, so I uninstalled this custom, to many micro stuttering with this.

JXD 1.0 => 50hz, Micro-Stuttering after Sleep.
JXD 1.1 => 50hz, Micro-Stuttering after Sleep.
JXD 1.3 => 50hz, Micro-Stuttering after Sleep.
JXD 1.5 => 60hz, No Micro-Stuttering after Sleep.
NCCE 1.0 => 60hz, No Micro-Stuttering after Sleep.
TheXSample => 60hz, Micro-Stuttering after Sleep.

Thanks for your great work.

in the article i mention about this

ALL firmwares have this issue, because after sleep, many times the screen is not running at real 60Hz (is a video driver issue)

we are looking for a solution, but for now the only way we know to "recalibrate" the screen is to change governor to Performance and back to your current governor (ondemand, in example)

this trick is not 100% effective, but is the only way we know to get this to work correctly.

thanks for the feedback.

I assure you, the JXD 1.5 ofw don't have this issue, the 60hz is not perfect but no micro stuttering (tested on many 2d snes games).

But with this custom, micros stuttering is here like the JXD 1.0-1.3, so it's strange...

Maybe we don't talk about the same stutter I can't show you because it's very very hard to catpure these stuttering with a camcorder...

I use the Performance Governor @1.5Ghz for all my tests.

Hi,

So, yesterday evening, I flash the S7300.
All is OK.
I try some Android games...and I download spiderman.
I start thé game and he begins to download additional data....

And freeze.... I must turn off thé device and...... go sleeping :-)

These morning, I'll start the console.....and nothing.....

Only a black screen..... and the groen light.

I try enter recovery but impossible :-)

So, I néed your help to debrick the device...

Do you have a tuto somewhere?

thanks

Donc pour ceux qui n auraient pas compris....j ai un joli brick....

Après avoir flashé, j ai voulu lancer spiderman et lors du chargement des données supplémentaires....ça s est planté.
J ai éteint en laissant le doigt longtemps appuyé sur le bouton power....et depuis, plus moyen de la rallumer...
J ai juste un écran noir....et impossible de rentrer en recovery

voilà :-)


ced

Try pressing and keep power button for 20 seconds.

wait for 5 secs

turn on again your device.

most probably is in a deep sleep state, and for this reason is not turning on

about freezes, try downclocking the cpu and test. the wifi is very unstable on this unit and most probably you can get better results if you work with less CPU GHz

try using 1GHz (configure with SetCPU, in example)

alex

i'll tell this issue (stutterings) to the team. but i'm sure is a screen driver related issue and happends on all firmwares for now.

Zalu2!

thanks deen,

I'll try this evening after work :-)

But, i don't have many hope because, thèse morning, I try many times to turn on, turn off...enter recovery...keep long time power button....

So, we will sée :-)
