Hi, i am new here and i have a tablet O+ 9.76 pad, it has:

 

rk3066 chipset

linux kernel 3.0.8+ zjw@tchipserver2

android 4.1.1 JB

16gb internal storage

1gb ram

9.7in IPS screen

3mp and 0.3mp dual cam

8000mah battery

 

i followed the cwm recovery installation from arctools, downloaded and installed thru arctools but it only shutdowns the tablet upon selecting restart recovery option from arctools. I tried pressing vol up + power button for a minute and up but it doesnt go to boot recovery, it didnt startup either. But it startsup when I only press the power button. 

 

Can someone help me install CWM in this tab and if any custom roms available for this? Thanks..

Is the stock firmware available or is the tab rooted so we can dump the system files?

I foolishly edited build.prop thru ES File Manager for a bravia engine tweak, installed it thru pimp my rom but only the xloud and clearaudio were inside build.prop. I rebooted and boom presto! Bootloop..

 

I have a backup of my old build.prop in my external SD card..

I also have an adb backup (backup.ab)

I cant access recovery menu, tried all possible combinations (vol up/down + power) same result, either wont boot or just normally boots then bootloop..

I also cant access fastboot mode so I can push the old build.prop..

ADB cant recognize my tablet due to the bootloop, I cant turn usb debugging on..

Moborobo either cant access my device..

 

What should I do? Help me please..

Sounds not good. Is this a full backup of the firmware? Pls upload the backup to an filehoster and post a link. I will check.

Nothing useful in this file. You may can do a backup of the firmware by RKFlashtool: http://www.freaktab.com/showthread.php?10129-Backing-up-your-RK-device-%28ROM%29-with-the-new-RK-2-1-tool

I saw this from the tutorial link you gave me..

 

"BIG NOTE:
This is really for backing up and restoring. This is NOT for trying to recover from a brick!
So only use this if you know how to flash a ROM and have a ROM available you know works already!
The reason is this procedure will not be flashing loader or repartitioning NAND!
Thus you need a good loader from a good ROM already flashed on your device!
In fact to even backup, your device must be working or this will get you no where!"

 

Q: How can I enter flashmode? 

RK flashtool only reads 1 MSC device found when I plug my device..

Yes, we need at least the kernel. Put all cable (usb and charger) in. Press power and vol up until you hear a sound on the PC. Then relase power. After RKFlashtool shows "found" you can release vol up.

I am following the instructions, RK flashtool showed "Found One MSC Device"

 

I am doing this part now:

"To do ANY dumping we need to dump the parameter file of the ROM from NAND.
Why? because we need the start (offset) and count (size) of the partition or we can’t dump anything.
1) Click the advance functions tab.
2) At the bottom is the "export image" button and to empty boxes, Start and Count.
3) To get the parameter file put a 0 in the start box and a 2 in the count.
4) Now press the export image button."

But when I press the export image button, an error occured saying "Match device type failed, stop running!"

geez..

Ok, your system is corrupted anyway, so we can flash a CWM into the tab.

http://crewrktablets.arctablet.com/?wpfb_dl=410

Flash according to instructions. When boot into CWM then do a backup to external sdcard. Upload the backup.

Ok, i followed the insturction..

 

RKAndroid tool detected my device as "Found RKAndroid Mass Storage Usb"

 

1. Copy Oma_Odys_Genio_Root_Script.zip to the root directory of you SDcard.

2. Hard power off your Odys Genio (hold power button until it powers off)
3. While holding Volume+ (up) button
4. Plug USB into your PC (update mode)
5. Install missing drivers from driver folder if you have not already

6. Run RKAndroidTool.exe
7. Unselect option 2 (Parameter)
8. Select Flash Rom

 

When I select Flash Rom, an error occured saying "MSC Device can't do upgrade"
