Password is geekbuying.com
Updates:
1. Solve problems of some apk software can not be installed;
2. Replace the default input method to Iflytek input method PAD version;
3. Improve system stability;
4. Solve problems of some apk software can not be searched in Google Play store;
5. Part preinstalled Apk software updates.
Upgrade Method:
Note:
1 Recommends Tablet PC power above 60%, to prevent power shortage caused by a failed upgrade.
2 Please backup important personal data, prevent file loss.
Steps:
1 Download the firmware, extract the following five documents:
patch.zip
update.zip
factory_update_param.aml
recovery.img
u-boot.bin
2 Prepare a TF card capacity 16GB or less, then take the TF card formatted to FAT32 format on your computer.
3 Please copy five files to the TF card.
4 Power off the tablet, insert TF card.
5 Press and hold the volume + key, then press the power button until the tablet is displayed a small green robot on the screen, release the button, the tablet will be updated automatically.
6 When the tablet turn on automatically, the upgrade is complete.
Maybe there are some doubts about this tablet:
Q: V975M support 4K video?
A: Yes, V975M can support 4Kx2K video decoding play, so 4K video and 2160P video playback is no problem absolutely. In video playback, Onda will constantly optimize video playback through firmware upgrades.
Q: Why is marked capacity of 32GB, only display 23GB?
A: Available user space on the tablet is divided into two parts:
1, Due to the memory algorithms of the total space are not the same in manufacturer and device system, resulting in visible capacity of the system is less than the nominal capacity is displayed . To 32GB V975m models, for example :
storage algorithms for manufacturer: 1GB = 1000MB, 1MB = 1000KB, 1KB = 1000byte; therefore 32GB nand memory show in bytes as: 32GB = 32 * 1000MB = 32 * 1000 * 1000KB = 32 * 1000 * 1000 * 1000byte
storage algorithms for device system: 1GB = 1024MB, 1MB = 1024KB, 1KB = 1024byte; therefore 32GB nand memory show in bytes as: 32GB = 32 * 1024MB = 32 * 1024 * 1024KB = 32 * 1024 * 1024 * 1024byte
Due to hardware manufacturers and software algorithms are not the same , 32G nand converted to the system ‘s algorithm , the actual size is: 32 * 1000 * 1000 * 1000byte = (32 * 1000 * 1000 * 1000) / (1024 * 1024 * 1024) GB = 29.802GB
2, The software and systems will take up some memory, showing below:
The factory bad blocks ( 2.5% or less ( about 745M))
uboot region space ( about 32M)
Drive reserved area (48blocks, 96MB or 192MB)
recovery partition memory ( about 32M)
misc partition memory ( about 32M)
logo partition memory ( about 32M)
system partition memory ( about 1024M)
cache partition memory ( about 256MB)
data partition memory ( about 2048M)
FTL algorithm of partition memory will take up about 1.2GB
User visible capacity = Actual capacity – Factory bad block – uboot region space – drive reserved area – recovery partition memory – misc partition memory – logo partition memory – system partition memory – cache partition memory – data partition memory – file system overhead – FTL algorithm of partition memory = about 23.9GB (Process of system operation will cause some additional consumption, may be smaller than the actual capacity of 300MB)
