seems to BRICK my MK812A !

After update, there is only endless android boot logo running on the screen
(well at least for an hour, then I have disconnected it).

Also I can not connect my device any more to PC for another firmware update,
there is no Windows ping, and RKBatchTool.exe v1.7 does not recognize the device !

Please advice, what to do to un-brick my device .

By the way, it is MK812A with Bluetooth and 1 GB RAM, bought from AliExpress.

Step by step (writing by memory, because I can not do it any more again)

Installed drivers from RockusbDriver_3.5 - x86 - Win7 .

Started RKBatchTool.exe from Rockchip_Batch_Tool_v1.7 .

Program recognizes device and field 1 was green.

Selected your firmware image rk3188-bt-0626.img , and started upgrade.

Program writed firmware and checked it, last line was green.

Connected device to TV, applied power and android logo started running on screen.

And it is still running (after trying it few times, even for full hour).

Please help.

Answer to your question

Were you able to enter into the update model? You should not see anything on the screen in the model. If you saw Android Logo on the screen, it meant you have not entered the model yet. In this case, check out your update steps, and do it all over again.

Please see my previous post :

Not wanting to offence you, but from your first post in this thread I see you are from
customer service department. Please ask some of your technical guru what I have to do.
Please help.

Hi doobol,

The firmware is great. Thank you for posting it here.

We are looking for a 1080p ROM. Could you please make a true 1080p Rom and post it here.

The device is great too. Thank for creating such a wonderful device.

Also is there sources available for this ROM? Can you publish the sources in a git hub or some where?.

Thank you once again for the support!!.
