Gents,

this a Flash-Tool by CrewRKTablets which provides:

a) generic TWRP's 2.8.4.0 for landscape and portrait orientation
b) a generic CWM 6.0.5.1
c) a root-script to be installed via TWRP/CWM

So, it can be used on any rk32board and to root any rk32board

- generic, that means no kernel and resouce included in the image
- full touch and usb-mouse support (not supported by some kernel)
- volume rockers support (only CWM)
- backup and restore of all partitions (boot, kernel, resource, recovery, system, data)
- backup and restore of internal sdcard (only TWRP)
- advancend restore (i.e. restore data)
- advanced backup (only TWRP)
- install zip from external sdcard (i.e root-script, gapps, fixes, themes)
- wipe (factory reset) and advanced wipe
- possibility to theme the UI
- some more functions, which we do not need (so, untested)

Flash instructions are included in the download pack.

FAQ

Q: Which resolutions for TWRP are available?
A: Landscape 1280x800, 1920x1080, 1920x1200, 2048x1536, 2560x1600 and Portrait 800x1280, 1200x1920, 1536x2048, 1600x2560. Orientation is defined by the orientation of your kernel logo.

Q: Why can TWRP not mount internal sdcard?
A: What is a valid reason to restore a backup? When the build is crashed or you try a new/other firmware. In both cases you have to wipe the NAND. So, internal sdcard (partition on the NAND) is lost. That's why we think working on/with internal sdcard is not very useful. On the other hand you have most likely game data (obb and user) on the internal sdcard, which will also get lost. Disabling the internal sdcard in the TWRP code will give the benefit to also backup/restore the internal sdcard.

Q: Why shows TWRP an error mounting sdcard?
A: Latest RK32 builds has unified internal storage, which is btw. Google standard since long. So no internal sdcard partition any longer. The error shown is irrelevant.

Q: Why can TWRP not mount usb storage?
A: This is an unsolved bug by now.

Q: Why can I not shut-off the tab from TWRP?
A: Rebooting options depends on the power management chip and it's programming. In some cases proper function of the chip is not independend from the kernel because the kernel flashes every times code in the chip. The majority of the tabs comes with an "always power on strategie", which means only Power Button and USB-port to communicate with the loader. That's the reason why these tabs boot into Android when usb cable will plugged in. Also tab will not shut down when usb cable is plugged. So, that's not a kernel issue it is a kernel feature.

Q: Can I theme TWRP?
A: Yes, there are some PLAY themes in the pack, to be installed via install zip. Happy if somebody can provide more themes, especially for landscape.

Be aware: it is your own risk!
