When you update the device from SD card with the firmware IMG format or OTA updates of the device partition 'Kernel' not updated! When you update the device from SD cards with the firmware from the device manufacturer it is not recommended to use the 'TWRP Recovery' and it is recommended to restore the original recovery, which was before installing the 'Recovery TWRP'! Especially when on different devices, the backup folder will be marked the same! In your 'TWRP Recovery' in the process of creating a backup folder is created with the name 'rk30sdk' that can cause problems when restoring if the partitions 'Boot' and 'Recovery' will contain the 'Kernel'. It can be used on various compatible devices if the process of mounting partitions is the same. Most tablets use a 'TWRP Recovery' without a 'Kernel'. When you killed the partitions 'Boot' and 'Recovery', the device is loaded in the mode 'BootLoader'. To restore the firmware through RKBatchTool, enough working 'BootLoader' in the device (is not contained in the Kernel!), drivers installed on PC and full firmware in IMG format. 'Kernel' - something like a drivers needed for Android OS under the device. A sense to make a backup of the kernel? If you create a backup of Android enough to have saved the sections 'Boot', 'System' and 'Data', which actually should not be tied to the 'Kernel'?īoot partition can contain an updated 'Kernel', if it is newer than what is contained in the section 'Kernel'.
