Head Unit Dead

Hello everyone, I have a Pumpkin RQ0255 (rk3188) unit: rk3188-eng4.4.4 29032016 firm
What happened is that I wanted to upgrade to the firm Malasyk, but after installation is complete, the unit will not boot again, the screen is dead.
When I press the reset button, the lights blink one second, but nothing happens.
Anyone can guide me ??
Thank you
Had the same issue, read through this! I used a windows 10 laptop and it all worked great!

You do not have a Pumpkin, they are sellers, you probably have a Klyde but you cant find out until you get your screen on. I suspect that the problem is that the Malaysk ROM that you tried to load looks for a "C" at the end of the MCU name and it is a later MTCC based ROM, you can probably upgrade your MCU to an MTCC one and not have the problem, but first I would install @dsa8310's ROM from here :

Post in that thread for more help.
I dont think @shawndak's suggestion is likely to help because it is for MTCD units.

Its in the MTCD forum but my unit is a MTCB. So it will work on a MTCB! Just flash the proper factory rom

Ah, I see.
No need to flash the factory ROM - @dsa8310's xposed mod fools the ROM into thinking theres a "C" at the end of the MCU version number, so it will work on any MTCB unit KLD MTCC MCU or not.

Good to know! I did factory after I got the black screen. Was nervous i'd mess it up even more if I flashed a different rom!

Panlelo / Ezonetronic Model: RM CT0011 Not starting

Helow,
I bought a navigation with android Panlelo (but after several searches I found out that it is produced by Ezonetronic) Model: RM CT001. After a month of use has stuck in the logo screen, starts the logo for 10 seconds and then resets. I would also need to write the andoid's software directly to mcu but I do not find this firmware to do that. Someone can help me with this. I received something from the producer, but it is an update to the system and it does not work unless the boots system. Something that does not happen to me. I need this help to keep it out just a dust support after I give the money on it.
Thanks in advance
