Hello. I have CX-919 with RK3188-T and RTL8723BS for bluetooth and wifi. I tried to flash the stock rom again using Rockchip Batch tool. The process succeded but after that ,the tv stick wont boot. I have to say that i didnt changed anything in the development menu such as usb debugging options . what can i do now? does the stick have to be connected to tv while flashing a new rom?

As far as i am aware the only way out is to reflash the stock firmware, without usb your a bit stuck. what is the problem with the usb connection?
i am trying 3 systems xp w7-64 w7-32 all are device not recognized error in device maneger is yellow mark unknown device
You need to install the usb recovery drivers. They are on the advent/pov websites. I assume there the same as your tab.
i cant access my tablet because i have usb not recognized error i want any alternat method to flash my tablet rom like sd card or usb drive thanks
no one solved my problem any idea if i use usb to serial cable or usb to lpt cable
You need to sort the usb driver issue. That will solve your problem. As far as i am aware flashing the stock rom with any other cable is not possible.

Hi guys,
I have a massive problem.
I recently updated to 4.3 rooted etc, after a few days of not using my nexus 7 on the pc I wanted to flash a new rom.
Now my N7 is only shown as an "Unknown Device" in my Device Manager.
I tried to deinstall Drivers, install, everything, I tried every possibilty in Wug's toolkit, nothing worked. I also tried it on another Notebook where i have never connected any mobile device, same message and i'm not able to install the drivers.
I also tried several ports and cables(the original one included)
Here is the message:http://i.imgur.com/tgxOeZQ.jpg
Translation: The optimal driver software for your device is already installed.
After this I flashed back to 4.2.2 (downloaded the rom on my N7) while performing a normal factory reset, I can't wipe everything because then I am not able to flash anything.
So after flashing to 4.2.2 my N7 was shown as a portable device in my device-manager. I then turned on USB-Debugging to stock+unroot, it was then shown again as a Unknown device, in both modes, USB-Debugging turned Off and On.
So now my question, is there a solution to this? I searched for possibilites to get back to stock without USB but most of them were a bit sketchy or had dead links. Please help me (sorry for my bad english)
Edit:
I just the cable of my old Motorola Defy, and it randomly connects and disconnects(still shown as unknown), so basically I think it is possible that my USB plug is broken(it takes about 6 hours to load the battery which I think might be as well a reason for a broken USB plug).
But to send it back to Google I need to Stock Unroot first so here my problem is again!
greetings
hello
i have a problem with my g928f
my issue is that it can not be regognized by the windows
i have tried at my desktop with win 10 and at my laptop with windows 7 and at both says unknown device,
i have tried everything i know of
unistall everything from the pc regarding samsung drivers
install it again , nothing
install smart switch , nothing
install kies, nothing
run odin , not even see the phone at download mode
made factory reset from recovery , nothing
charge is working just fine both from pc and my wall charger
i tried mhl hdmi and nothing happened
tried just now otg cable with a usb drive , again nothing
just a week ago i was using it just fine with my pc
should i take it to a store to check my micro usb port??
noone??
today i replaced the screen with a new one witch had a new usb dock on it and the problem is still here
i can not connect it to any pc.
i cann't flash the stock rom because odin is not see it also
is it possible to be a rom problem????
i can't flash the stock one because of the usb issue
but i think i can download another lollipop rom to give it a try.
Have you made sure that it is set as MTP?
Setting - Storage - USB.
Check if the device gets connected in Fastboot mode. If it doesn't then it would be your USB.
sideload is not working either
usb is brand new and original.
is there a way to flash stock rom via recovery?
Hello everyone,
first sorry for my english.
I have Nexus 2012 with 3G modem. I had android 5.1.1 witch root and twrp, but was slowly and i made wipe. Then system doesn't work. I decide to install again 5.1.1 via nexus tool kit - tablet work. I connected rtl sdr dongle install sdr scanner - it's working. Reboot tablet and it doesn't work. So i tryed to install android 4.4.4 - and i have the same situation (of course have root) first install and sdr is working, reboot and it doesn't work. I have info " no connected device". Before i made wipe and tablet work slow everything worked fine. I use active hub, connect directly to otg cable - the same problem.
I don't have any idea. Could you help me? Dongle sdr connected to computer work.
Regards

Hello! I was wondering if someone could give me a hand. I have researched and tried several things to unbrick my TV box but no luck so far. I was using PhoenixSuit to flash a firmware to my Vontar V6 (H616) box and during the process Windows crashed. After the PC reboot, I noticed Windows 10 recognize the TV box (Device Manager) as Universal Serial Bus controllers -> USB Device (VID_1f3a_PID_efe8) but PhoenixSuit is unable to recognize it again as a device. I tried also flashing the firmware via PhoenixCard as well as accessing the box via adb and fastboot but no luck at all. Based on what I have researched, I believe the bootloader of the box is damaged. So any help or guidance to fix it would be mega appreciated. Thanks in advance, Marcello.
