CrewRKTablets_RK30_Genio by Oma_CM10.1_v1.3.5

CrewRKTablets_RK30_Genio by Oma_JB_4.2.2_multi window_v1.0

CrewRKTablets_RK30_Genio by Oma_AOSP_4.2.2_v3.3

RK30 Genio by Oma – 4.2.2 Beta Build v3.2


Important: from one noob to another – before actually trying ANY of these ROM installs for yourself, first root your device, install ArcTools and CWM and make a Nandroid backup of your current system (see my other or other people's posts in this forum for details) so you can GET BACK to where you started. (If you feel brave enough, do a restore with it too.) Second, if you think you've bricked your tablet, don't panic, there's usually a way around it (comments from more experienced users please??) such as getting it into CWM (recovery) or update mode (bootloader).

Quote from another thread by Oma:

You cannot brick a Rockchip device.


CrewRKTablets_RK30_Genio by Oma_CM10.1_v1.3.5

as recommended to me by Oma that I try first because "The CM10.1 build is more generic and can be better adapted for your tab".

Erase IDB, flash as normal.

Re-flash using "Oma_RK30_generic stock recovery" recovery.img (which is in fact CWM and with only 'Parameter' and 'Recovery' ticked in the RKTools window.

Booted up OK into Android 4.2.2.

WiFi or Bluetooth not working; everything else seems OK.

CWM window always shows Can't mount or open /cache/recovery/log errors.

Impossible to restore other CWM Nandroid backups without getting format error in /dev/block/mtdblock9 error.

CWM exits almost immediately during 'Saving boot.img....' if you try to make a backup on sdcard or ext sdcard.


CrewRKTablets_RK30_Genio by Oma_JB_4.2.2_multi window_v1.0

Erase IDB, flash as normal.

Boots up with boot animation and then through to Android desktop but display has the wrong resolution and weird colours. No touchscreen capability.

Reflash with Erase IDB but substituting provided kernel.img (3.0.8+) for RK30_kernel_3036_s1s_pipo (3.06+). Boots into v6.03.1 CWM.

Only Volume+ button working for navigation purposes.

Wipe data/factory reset.

Pipo splash screen and Oma's bootanimation screen with lightning flashes and it boots successfully to desktop with normal resolution and colours. The soft-button icons for sound, back and recent apps are on the bottom of screen on bottom, time and battery indicator at top, all on a solid black background wallpaper (ie no wallpaper).

Screen option comes on screen to choose Launcher as well as various SU requests, but none can be responded to as there is again no touch capability. (Still only Vol+ button working.)

Reboot gives date and time with slide unlock screen but with no touch it cannot be unlocked. Stalemate!!


CrewRKTablets_RK30_Genio by Oma_AOSP_4.2.2_v3.3

Erase IDB, flash as normal.

After reboot into CWM, run format_NAND fix.

Then endless loop of reboot system now, back into CWM, never reaches the boot animations.

Don't know what to do to resolve this.


RK30 Genio by Oma – 4.2.2 Beta Build v3.2

Two versions of this -

First: CrewRKTablets_RK30_Genio by Oma_AOSP_4.2.2_20130501

Erase IDB, flash as normal.

Does not reboot into CWM or JB.

Then: CrewRKTablets_RK30_Genio by Oma_AOSP_4.2.2_20130518

Likewise as per the other version - no boot into CWB or JB, just a blackscreen, no response from power button, only possibility is go into update mode with rockusb driver.



Erase IDB, flash as normal.

Reboots into Odys and then JellyBean splash screen.......then screen goes black with a bit of white light spill at the edges - and stays that way.

Hard reboot works, normal power on to same splash screens and nothing.

Re-flash using "Oma_RK30_generic stock recovery" recovery.img - success. Gets you into Genio JB 4.1.1.

Problems: home screen and apps drawer do not rotate to portrait (only landscape, both ways) but other pages such as settings and ES File manager do. WF turns on dut does not find any networks. BT does not turn on at all.

In File Explorer, says SD card (internal) is empty, unmounted or not present.

After rooting device (with the Kingo app) and installing ArcTools, I was able to reboot into CWM. From here I could use CWM Restore to reload from my Nandroid backups JB4.1.1 which was the FW that was originally installed on the device when it was delivered.


Tip: Having trouble rebooting into CWM? Then do this - hard reset (power button held down till device clicks). Press and hold Volume+ (up) while pressing power on for about 4 secs till first boot screen. Release both buttons, then press for a short time Volume+ (up) button. Worked for me!!


Conclusions (so far):

Although superficially the Genio and Fusion seem very similar tablets (same board, same CPU/architechture/both 7-inch/both the same colour(!!)) but they have different Wifi chips, so porting a ROM designed for the first device to the other one is not as straightforward as I first thought. Maybe impossible.......? Who knows?

Best bet so far seems CM10.1 – but no WF or BT functionality yet. Watch this space!!

[EDIT: Post#49

Oma says: It seems we cannot "correct" the strange "behaviour" of your kernel on the Android side. Sorry.

End of edit]


Still to come with further testing on my Fusion (someone please tell me if they know of a reason why I shouldn't bother....):

Oma RK30 JB v1.3
Oma RK30 JB v1.4 Win8 UI
Oma RK30 JB v1.5 SDK 2.0
Oma RK30 JB v2.4
Oma RK30 CM10 v1.2


[EDIT 2: No more testing possible because my Fusion developed a defective NAND and I am now in the market for another tab - suggestion for make and model please?]
