CX-919 II android TV stick bricked?

I bricked my device too

I don't think you bricked your device; first, try using a different hdmi cable or different display/monitor
if that doesn't work, it might be a software thing, after some research on your device, you'll find some flashing tools which you can use to flash different roms, if that is the problem, go to this thread http://xdaforums.com/showthread.php?t=2677979 , it is on rooting your device but i'm sure somewhere in the thread, you'll find the flash tool, if you don't, then download Finless ROM 1.6b (I've installed it on my cx919 ii 8gb rom, it is rooted and works perfectly [but there seems to be a bt problem]) http://www.freaktab.com/showthread.php?7553-UPDATED-CX919-4-2-2-Finless-ROM-1-6b
when you connect your device(windows only), you must manually install the provided driver in the file, don't let stu stu windows to install it, if you don't do it correctly, restart
here's how:

P.S. Yea... just hope you had the settings: usb debugging: off, connect to pc: yes/check mark, and connect as mass storage (not camera or mtp or something)

1. Open the flash tool (it should say something like: 'rk device not found' depending on the one u have)
2. Unplug your device from any power source
3. Connect a micro usb to usb cable to the otg port (i used a blackberry cable that was laying around, i believe the provided cable will work)
4. Then connect the usb to a port and imedeately press the 'fn' button (aka the one on the side)
5. Then in the device manager, manually update the driver for it with the one provided in the finless rom, be sure to update the device itself and not the drive/nand flash/ "memory"
6.Then in the flash tool, it should've found the device
7. erase nand memory/ idb
8. finally flash all the preselected items (that's how i bricked my device, when installing ubuntu, the files didn't have a recovery image so i couldn't conect it to my pc and reflash it)
Moment of truth, turn on ur device! u might wanna change some time settings cause some little problems with the rom like the time can bug u a bit

Hope it worked!
If i were u, i would do some more research, that's how i got this, u might stumble upon something and it might be a better guide then mine so just research it!

Now I'm gonna go find out how to fix mine!




Good luck flashing!

CX-919 II android TV stick bricked

Hi! I just purchased CX-919 II android TV stick. I was having wifi connection issues, so I decided to change the firmware with 4.4 kitkat. The problem was that when I was going to downgrade to 4.2 I had the usb debugging checked on. so now It seems my device is brick. the blue power light comes on, but the tv screen continues black with no sign og the system booting.
I´m RKbatch tool 1.7 and CX-919 4.2.2 Finless 1.6b with cx919-rk3188-4.2-6210-20131209 firmware
Can anyone help me unbrick my device, please?

Been there, done that.
When connected to the RKbatch tool, what message do you get?
Do you connect to a WINXP, 7, 8?

I messed my CX919II up when I flashed it using a WIN8 laptop. I tried everything to reconnect to my WIN8 laptop but with no luck.
I then tried on my old WINXP laptop and after installing the USB driver I managed to connect and flash my CX919II.
Now it's up'n,running again

Hope it works for you.
Cheers

Unbricking only with the short circuit mehod

I flashed it with win7. I already figured out what went wrong. it´s up and running again. I had to open the case of the CX-919 II / J22 / EKD03 Quad Core Rk3188 Android Smart TV Stick. Although it still connected to the RKbatchtool 1.7 it was always hanging up on the IDB preparing. - IDB fail. So I had no other choice but to short circuit the 7-8 pins of the nan chip in order to flash it again.
I´ll try to leave a detailed guide in this thread:

It might be useful to anyone who buys the CX 919 from ebay chinese sellers.

Short pins 8 and 9

I experimented with mine and unbricked it, Thnx everyone, but I figured it out already, just put a metal thing like a knife or a paper clip on pins 8 and 9,it worked for me, ur tool will see it as maskrom mode, this isn't very specific so unless u no exactly what I mean, don't Try it pls, (I'm really busy these days with homework) ?good luck
