This picture is SOM. SOM is not MCU. Read forums/search for MCU fixes. Enjoy your time at xdaHi all, I have a Dasaita PX5 for Peugeot 208, unfortunately after installing the MCU (wrong version), the car radio no longer starts, useless attempts to enter recovery, nothing.
The touch keys keep flashing but nothing is seen and nothing is heard if I press the buttons, so I came across this guide and made the connections, slightly different because mine is a 76 pin SOM, HCT-PX5 rev10 , in any case, after a few attempts I saw that the pc reads the device quietly and also the rockchip tool sees the device, but when I load the android 6 image and press update I get this error "TEST DEVICE FAIL" it is not that apparently everything seems ok but there is a problem with the connection? or should I try with Android 8 if it comes out by default with that version? the chip is the RK3368 it is reported on hwdinfo on the Platform item, the MCU version is MTCE_HA, do you have any idea?
This SOM is a 76 Pin board, maybe that error program for some wrong connection, does anyone have a more detailed picture of how to connect the wires?
As for the resistors, I'm not sure I've connected them well, today I should receive a package from Amazon containing all the resistors needed.
I hope someone can help me. Thanks all in advanceView attachment 5973285
I also faced this question myself and this thread did not contain a workable answer for me. I have the impression that the pins to short in order to force mask rom mode are not on the SOM board but on the mainboard and hence vary from device to device. But I may be completely wrong.
Hi, what ROM version did you have before uploading the second ROM, I assume different ANDROID versions, that's why the BOOT partition got damaged. It is necessary to make a boot sd card.Hello, sorry for my English, I live in Germany. My px6 car stereo with rk3399 chip got stuck on the Android boot screen during firmware update. I made a USB cable as instructed, but the computer doesn't recognize the connection. I installed all the drivers and did everything correctly. Which contacts do I need to short to enter maskrom mode? The board revision is 10. Thank you for your help in advance!
Yes, on the first page of the thread you will see PX5 boards, both the green one and the blue one.
No, you can cut and use any USB cable that have at least one male plugs at its ends.
