Hi there
Thank you for your reply
But I'm a little bit confused, the video shows exactly the radio turns on, but in the previous message, you said the radio is totally brick and do not turn on any more? Did I misunderstanding something? Sorry for my poor English, but I'm really confused.Please do not care the recovery issue now, just make sure the system and mcu are updated, you can check the version info. on the setting my friend.
Regards!

OK, once again. You are confused. This is schema/schledule of my head unit:

Unit = Pumpkin radio

10/2015 - New head unit arrived from seller star_cardvd from Ebay

11/2015 - instaled in my car. Starting problems with connect an interface Connects2 to unit. Not solved to nowdays. Interface works correctly, but Unit didnt decode signal.

12/2015 - I found the problem with hard reset of Unit- I tried to make correct procedure (as is shown in this topic(and in others) from you) - without result. The Unit couldnt get to recovery menu.

1/2016 - Radio app crashes - I wrote this topic to solve that - after reinstal the app this problem has got OK.

31/1/2016 - I asked to you how i can to turn off the radio app without reboot.
I also pointed out the problem with reset of Unit. I made a video (second half of video with coments)

01/2/2016 - You advise to me to reinstal whole system, at step 1200 in reinstaling MCU unit got completely brick on black screen.

01/2/2016 - to now - Unit is still bricked on black screen. Iso cable is instaled rightly, Unit was 20 minutes without current for test. I reconected it back, made procedure to hard resset, but nothing happens. Still black screen.

Please read this topic from first subscribe.

Hi there
Thank you for your reply!
I'm sorry about that, but normally the firmware installation will not cause the radio brick, unless there are other operation done during updating or any power current unstable or card issue. You can see the video I sent to you, it is not have problem after updating. As it is now already become brick, please directly conect the retailer from ebay to return the item back for repair, ok? If you want direct ask me to help you return the item, I can help you do that too, but please personal message me as it is include your private information on it, ok?
Hope you can understand!
Regards!
