About My player JXD 921

I have 5 days back recently purchased JXD 921 I thought it was 921+ but it was old version 921
Techical problem.
My player was working fine. I check the JXD web site that jxd 921+ have additional features like RM, RVM which does not need conversion of media format. Picture viewing in 3D display so I thought to upgrade the firmware to make my player with add on features.
So No update was present on JXD site and nor in English version of JXD new web site.
So I tried search of firmware on google and found a thread. He uploaded a Aimg, Bimg and firmware files following are the files
Ref img http://i604.photobucket.com/albums/tt123/manujsingh/JXD/filesdwnload.jpg
Files download
a) Aimg Size 52.0MB
b) Bimg Size 2 MB
c) Firmware (.bin ) Size 4.63MB
What I did
I switch on 921 JXD player than gone to Tools option >select update option > selected USB mode.
After that I opened FRM v2.6.24 when it loaded on basic menu I can see on top ISP ver [0000.0853] ref picture (FRM.jpg)http://i604.photobucket.com/albums/tt123/manujsingh/JXD/FRM.jpg

Even if I clicked on USB button after few seconds the popup shows :-
“USB Device connected!ISP VER: 0.853”

Than I moved to advanced column than Set Working folder > selected the folder on desktop named FRM the files came under working folder on right side
than I select A folder on working folder right side and right click on options selected "burn selected" same did with B and Firmware(.bin)
options coming on right side on right click. Refe image http://i604.photobucket.com/albums/tt123/manujsingh/JXD/mistakefig2.jpg

JXD 921 snap when GREEN light glows and LCD does not turn, but this device is detected by my computer as a 2 removable drives 1st as internal memory which contains the default files, and 2nd my SD 2 GB kingston card.
I reconnected to USB cable my system shows me 2 removable drives one for internal which contains same folders like DCIM, Ebook, flash, game, mp3 (ref image aft mistake01) Ref picture “Folder auto create files screenshot”

and When I try to delete or format the I:\ removable drive ( which is JXD internal Memory) it completely deletes all the folder than when I again restart the JXD 921 my computer shows 2 removable drives and internal Memory still gets the folders back in I:\ which were formatted.I tried again using the FRM so that my player can be reset to original from has I have files of JXD 921 of my player as a back up

You are in a Meizu Forum JXD is another chinese brand....

This player has a serious complicated firmware upgrade?
I say this only once – you not going find much help in here. Besides this brand is completely unknown to me.

Still I think I can help you direct to the right place to find that help you want.
