PUMPKIN CAR STEREO SUPPORT CENTER

Hey,
i´am from the german site China-RNS. I have a big Problem an other user say that i must contact you (sorry for my englisch ).
I have a Pumpkin SKU:12-RQ0415-DE-ADE 4.4.4 Android Radio.
i started a flash Update 5.1.1 FUSE 1024x600_RK3188_06_MAL_30_10_2016_MTCB
the "update" wasn´t succesfull, 25% at the installation, the radio restart and the screen are grey.
i hold the power button for 30sec for recovery, but nothing happens- the radio get off. restart is only possible when turn acc off and on or press reset button- the screen is grey again.

where can i find the recovery mode? is the radio malfunction?

Hi,
I can send you the original firmware to check, but I'm not sure it could make your unit back to work.
Here is the link for you.

You can refer the below video to enter the recovery mode and flash the unit. Hope some help.

I have to remind you kindly, Please don't install any other update firmware or mcu, it's easy to damage the unit.
Regards
