The threads which originally published this information, of which I have taken part in generating this entry are as follows
Skelrom v1.0 (Forum on Spanish , English )
ClockworkMod Recovery (Forum on English )
For direct inquiries and information regarding these issues, I suggest posting in the forums mentioned.
Introduction
As some of you know, the last time I've been helping to try some custom roms being developed for the console JXDS7300B, and of these, which is the best feature has finally been released.
Led by Skelton, known as the android console scene for his series of custom firmware that greatly enhance the experience of using these devices comes the (long awaited) Skelrom custom firmware v1.0 for JXDS7300B, and to make a summary, I copy and paste part of your readme.txt

Key Features:

  • Based on the latest stock firmware (v1.3)
  • All applications and Chinese emus eliminated Gamex becomes a user application and system
  • Improved Google Play almost all apps should be no problems
  • And zipalign Deodex. (Makes auto-zipalign on every boot if necessary)
  • Fix for q emulators were not consistent and improved the compatibility with gameloft games (Nova 3, Modern Combat 4 ... etc)
  • Includes SetCPU XDA donation version installed with default profile.
  • Fixed problem with ac3 and dts codec in hardware mode with mkv files, so no more noisy sound every second with these codecs.
  • Support for uinput
  • Battery percentage shown
  • Support for init.d scripts.
  • Improved build.prop to improve the consumption of the ram, screen response, etc ...
  • SetCPU donation version installed profile series.

The ROM does wipe automatically, this means you will delete all data you have on the console (quiet, only the data from the console and from the internal memory. Microsd will not sound) so keep that you want to keep your data before installing the rom.

Installation:

  • Unzip the downloaded zip to the root of the micro SD.
  • This should give you the following files in the SD: Factory_para_update_aml, update.zip, uImage_recovery
  • Turn the s7300B JXD recovery mode with Power + menu and wait for it to finish the whole process

Considerations:
In this ROM, or future (if any) will not be included payment software, to avoid licensing and distribution problems.
SetCPU version is the version of donation and the author's permission to include it.
The default speed is 1.32 ghz, you can climb to 1.5 with another kernel included in the extras folder. or using SetCPU. Note: You can also directly upload speed with SetCPU without flashing another kernel (tested by me)
The kit includes the following extras:
Kernel1500.zip - (It is not necessary, as mentioned above, but if you want to try flashing this file from recovery if you put 1.5 ghz)
Kernel1320.zip - To return to 1.32 ghz
SWAP_ON: This file will exchange the internal and external memory, so that the external is / sdcard / and internal / sdcard / external_sdcard /. Thus keep in mind that if you're removing the microSD disassembled the inner well.
SWAP_OFF: SWAP To remove the console and put the partitions to their original state.
More specific instructions in the Extras folder to install these files.
About SWAP_ON / SWAP_OFF ??
This method works without problems, but had some strange behavior with large capacity cards.
Some cards of 32GB, and (to my knowledge) all have 64GB a problem starting the console, and is not properly mounted at boot android. If so, how to solve this problem is to remove and re-insert the microSD slot is mounted correctly.
This has a parallel problem. In the event that not mount properly at boot microsd system will not generate the / sdcard / external_sdcard, this means that when we mount the microSD manually in the system properties see "duplicate" information from the microSD in external memory, and can not access the device's internal memory.
Therefore, if you do not mind losing some Gigas 6 and we have available in the internal memory, microsd have a large capacity, then uses this system. If not the case, then I suggest using the traditional system or GL2SD DirectoryBind to link content to external microsd.
In addition, there is possibly a problem when trying to display the memory capacity (storage) and system settings are closed. For this case, simply create the folder "external_sdcard" on microsd to system settings stop close (fail stop)
ClockworkMod for JXDS7300B
In addition to custom firmware, has launched a fully functional version of ClockworkMod for JXDS7300B. Skelton Besides having worked in this port, we must thank the real creator of this custom recovery, Christian Troy, and thanks to him and his help has been fully carry this Recovery, which for those who know him know the importance , is that you can do with nandroids complete the device.
What's a Nandroid?
Basically, it is a byte for byte image of the contents of the flash device, and turns in a file, which can later be retrieved the system, programs and settings that we had when generating the nandroid.
Furthermore, this method allows the creation and distribution of custom roms, without preparing kitchens dedicated to the device, or in other words, anyone who wants to dare can generate your custom rom without complications. Yes, watch the personal settings that can go in the file, because this nandroid saves everything from the name of the wifi we have at home, so we use google key to enter the market.
Features of this version of CWM.
Unlike what is normally seen, this CWM is started directly from a microSD, because for security reasons not flashing in the device (this recovery partition is larger than the device, and may generate a full flashearla brick) , but it's almost better, which means that the device runs with its serial Recovery unchanged, and we can boot a custom recovery from external media.
For more information CWM, suggest looking at these threads
In Spanish, in gp32spain
In English, OpenHandhelds
and samples, a video where some of this work ahead
Final Words
That said, we've been testing this custom for a few days, looking for bugs and polishing (well, skelton in this case) as best we could, and I think the result is significantly better than the official firmware for JXD offered.
I hope (hope, will speak on behalf of the "team" has been working on this custom) firmware that will be useful for owners of a JXDS7300B, and henceforth we await that follow JXD releasing firmwares that effectively fix problems that have been detected in the device.
