| Are you using the pure Android firmware without Ubuntu ?  If that's the case, you can try the following steps. 
 (WARNING: Please backup all of your important data first!!!) 
 1. Go to http://wiki.t-firefly.com/index.php/Fir ... h_image/en to get ready for the flashing evironment,   such as installing rockusb driver, connecting device and configuring AndroidTool. 
 2. In the extracted directory of AndroidTool_Release_v2.3.rar, use a text editor to open     "rockdev\rk3288-3.10-uboot-data1G.parameter.txt". 
 The line prefixed with "CMDLINE:" contains the partition info: Copy the codeCMDLINE:console=ttyFIQ0 androidboot.hardware=rk30board androidboot.console=ttyFIQ0 board.ap_has_alsa=0 init=/init initrd=0x62000000,0x00800000 mtdparts=rk29xxnand:0x00002000@0x00002000(uboot),0x00002000@0x00004000(misc),0x00008000@0x00006000(resource),0x00008000@0x0000e000(kernel),0x00010000@0x00016000(boot),0x00010000@0x00026000(recovery),0x0001a000@0x00036000(backup),0x00040000@0x00050000(cache),0x00002000@0x00090000(kpanic),0x00180000@0x00092000(system),0x00002000@0x00212000(metadata),0x00200000@0x00214000(userdata),0x00020000@0x00414000(radical_update),-@0x00434000(user)
 
 
 The Android data partition is "0x00200000@0x00214000(userdata)", which is in format of "SIZE@OFFSET(PARITION)" with 512 bytes (a traditional disk sector size) as unit. Therefore, the userdata partition as a size of 0x00200000 * 512 = 1G bytes. 
 If you want to expand it to 2G bytes. Just change the size to 0x00400000, and adjust all offsets of partitions afterwards. Here is the full example of 2G userdata partition: Copy the codeFIRMWARE_VER:4.4.2

 Save it as new file "rk3288-3.10-uboot-data2G.parameter.txt" in the same directory of the 1G variant. 
 3. Run AndroidTool.exe (with administrator right if neccessary), follow the steps as shown in the follow image: 
 
 
 4. The device will reboot into Android again. Please do a factory reset and wipe alll the data. |
