now its gone to bootloop and i cant access recovery, HELP PLEASE!

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..

its only 37mb, i guess that wasnt a firmware backup.. What I did was adb backup /all

 

Attached file..

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..

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, 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"
