Today I’d like to share with all the stock firmware for CX-921 Quad Core TV Box with Bluetooth Function, and the update method, the same method with K-R42

2 Power on the CX-921 tv box with the power adapter in package;
3. Unzip the flash tool to your desktop or other convenient location and locate the folder RKBatchTool1.6 – inside this folder is the flash tool program RKBatchTool and the USB drivers for the CX-921 – Don’t open anything yet!
4. Unzip the stock firmware you just download, and you will get a file named: RK3188_BOX_U42-1_BT4.0_20130819 (1).img or similar, this is the actual firmware file.
5. Next you need your CX-921 and the mini USB – standard USB cable that came with the device.
6. See the pictures below. You need to press the small recovery button on the back which show in the photos
I got a CX-921 – from geekbuying and it all seems great
But I need expert help – I flashed walter77_V1_ROM.zip on to the device and was wondering if any of you geniuses know how to change a parameter file over to my specifications. I would love a parameter file for this rom setup that basically divides the memory into 8*8 as every parameter file I tried from other ROMS will not work with it. Below is a copy of the original file.
FIRMWARE_VER:4.1.1
MACHINE_MODEL:rk30sdk
MACHINE_ID:007
MANUFACTURER:RK30SDK
MAGIC: 0x5041524B
ATAG: 0x60000800
MACHINE: 3066
CHECK_MASK: 0x80
KERNEL_IMG: 0x60408000
#RECOVER_KEY: 1,1,0,20,0
CMDLINE:console=ttyFIQ0 androidboot.console=ttyFIQ0 init=/init initrd=0x62000000,0x00800000
mtdparts=rk29xxnand:0x00002000@0x00002000
(misc),0x00008000@0x00004000
(kernel),0x00008000@0x0000C000
(boot),0x00008000@0x00014000
(recovery),0x000C0000@0x0001C000
(backup),0x00040000@0x000DC000
(cache),0x00400000@0x0011C000
(userdata),0x00002000@0x0051C000
(kpanic),0x00100000@0x0051E000(system),-@0x0063E000(user)
I think I only need to adjust the last 2 lines but I don’t know how – this is the original file with internal storage set at 2gb and nand having the rest of the 16 gb
I would love it if someone could tell me how to memory into equal halves.
you can email me the answer if you would like.
