[XDA Assist] dassad:
Hy there,

(forlinks please scroll down to bottom of the post since i couldn't post them being first time poster)

I bought a few days ago a "Captiva Pad 10.1 QUAD HD" used from a friend. The battery suddenly died in the way that run

out of battery and never started again, started and worked fine if it was put on charger. In settings/Batter showed

the battery 100% charged and 0s left.

This is the smaller issue now since I managed to brick it. Have rooted few tablets and phones in the past and

installed stock or custom rooms so I'm not a complete noob but for sure a newbie. Searching for it found nothing

about, removed the back of the tablet and saw that runs on a RockChip so tried that way and managed to root it. Super

SU everything was working just fine so was time to install a new ROM on it. Since there isn't any stock ROM released

by the manufacturer tried to find one based on the chip.

This is the point where things gone bad since i didn't made any backup at all. (I know, noob mistake)

There wasn't any driver for it so I just rewrote the Google Driver and worked fine, was recognized by RKBatchTool

which is basically like Odin and works the same way only that this one is for RockChip as I understand.

So everything was set up, downloaded 3 different ROMs in the HOPE that one of them will work... Downloaded these ROMs

from various places so can't give a link to them but here they are, maybe the filenames say something:

Geekbuying_TV BOX_RK3188T_Android 4.4_official_AP6210 (which I thought that will work since is the same chip)

kasty-rkm_mk902-442-20140515-rooted4 (just a random one i stumbled upon during my searches) (can't install as

noticed later)

radxa_rock_android_upgrade_from_sdcard_140314_update (another random one)

First run was given for the "Geekbuying" since at least had the same chip, the installing went fine with RKBatchTool

but the tablet never started again and had just a blank screen and there could be heard a THICK when powering

on so there was some life in it which gave HOPE but. To enter in download mode until now you had to push Volume UP +

Plug the USB in the meantime and this was working fin until now but not after installing this new ROM.

Today after searching more after it and learning some so i can manage somehow to get it working i came across a forum

which said that putting on short two of the NAND chip connectors can get you into download mode. Tok off again the

back of the tablet, and to make things even complicated there were two identical chips both NAND as I recognize them.

Nothing to loose, I tried the first one, the thread said that you have to short circuit the 4th and 5th connectors but

wasn't working for me, so tried other and worked with 8-9 connectors. I was again in download mode so could try other

ROM's. Downloaded from various places, read a lot about them but looks like not enough.

Here are all off them: I can list them by name if there is any need: (LINK 1)

The top three ones come from the Captiva page: (LINK 2) (none of them working)

Also figured out that Captiva is a product or "Nexoc" German company so tried my luck here to:

(LINK 3) (none of them working)

The one ROOM with which i can get the best results is the third mentioned above

"radxa_rock_android_upgrade_from_sdcard_140314_update" don't even know from where but as i have to realize now, this

ROM is made TV USB stick or a Media Box. I have installed this one and with this currently I have these results:

- The screen shows some light o the front but still dark and nothing shows up

- on the back the screen is bright white: (LINK 4)

- It is recognized by RKBatchTool, and i can even "Switch" between Normal and Download mode from it

- It was recognized as "radxa rock" by my PC and different Hadware id which was strange but wrote again the Google

Driver for it and it recognized perfectly in the PC and the content of the mounted drive is completely blank which is

also strange

- I had to try if it's working at all or is a screen problem so grabbed three different android screencast JS APPS and

all three show up this screen: (LINK 5)

- In one of the screencast apps I can even open a website but nothing else works from them, i can't push any button or

anything, tried chmod 777 dalvik-cache everything i could imagine

- ADB Shell works as far as i can use it

Some more details and under the hood:

- "adb shell getprop" prints the following:

C:\android\sdk\platform-tools>adb shell

I have tried basically everything i could come up, still not giving up and want to get this tablet running again at

least from charger if the battery won't work. So I would like to know what else i can try with it to get it working, i

can install other rooms and did that but had to put back this one since this is the best result I can get. Do you have

any suggestion what else i can check and what other ROM canI try, modified or stock i don't really care about it.

Looking for your help girls and guys if you have any TIP for me.

Tried to give as much details as i could but just ask if i missed anything or if you need any extra details.

Best regards,

daSSad
